Description

Technical Field

[0001] The present invention relates to a light generating system. The present invention also relates to a lighting device (comprising such a light generating system). Furthermore, the present invention relates to an arrangement (of such a light generating system). Background Art

[0002] Pivotable light generating devices are known in the art. For example, US20160102824A1 describes a lamp comprising a housing comprising a back and a plurality of side walls extending from the back, the back and the plurality of side walls defining an opening and an interior located in the opening. A light source is fixed to the back within the interior. A hinge is coupled to the housing and positioned within the interior, the hinge comprising a first portion and a second portion, the first portion and the second portion being configured to reflect light emitted from the light source. The first portion and the second portion can be simultaneously moved from the first portion (wherein substantially all of the light from the light source is reflected in a first direction away from the housing) to a second position (wherein substantially all of the light is reflected away from the housing in a second direction different from the first direction).

[0003] WO2015121761A1 discloses a tubular lighting fixture comprising a second strip of LED-based light sources movable around an arc relative to a first strip of LED-based light sources. Summary of the invention

[0004] More and more linear lighting devices are being introduced into the market. An example is the Hue Signe, which is a wall flusher that can be positioned in front of a wall to create a wall flush ambience effect. Linear LED arrays enable compact wall flushers, such as the Hue Signe. However, the Signe can be located at different locations, such as in the middle of a wall or in a room corner, which would require different beam widths and intensities. Current linear lighting devices are limited in their ability to adjust their beam width and intensity accordingly depending on the orientation of the lighting device. Furthermore, linear lighting devices are difficult to properly transport or store due to their rigid shape (i.e., limited flexibility).

[0005] Therefore, one aspect of the present invention is to provide an alternative linear light generating device, which preferably also at least partially eliminates one or more of the above-mentioned disadvantages. As stated in the accompanying claims, the present invention may have the object of overcoming or ameliorating at least one of the disadvantages of the prior art or providing a useful alternative.

Furthermore, the system can provide flexibility, i.e., it allows the linear orientation of the light sources relative to each other to be changed to achieve (manual or motorized) beam width adjustment. This flexibility can also enable easy transportation and storage of the light generating system.

[0008] In the following, some general embodiments of the system are first described, followed by some more specific embodiments.

[0009] In an embodiment, the light generating system may comprise the light generating device and the pivotable component. In particular, the light generating system may comprise a unit, wherein the unit comprises the light generating device and the pivotable component.

[0010] In an embodiment, the light generating device may include a first linearly arranged light generating device and a second linearly arranged light generating device. In an embodiment, the first linearly arranged light generating device and the second linearly arranged light generating device may have a first linearly arranged light generating device length L d1 and the length L of the second linearly arranged light generating device d2 In particular, in the embodiment, L d1 and L d2 L may be independently selected from the range of 0.5-150 cm, for example from the range of 1-100 cm, such as from the range of 1-50 cm, in particular from the range of 5-15 cm. Therefore, in an embodiment, the first linearly arranged light generating device and the second linearly arranged light generating device may have a selected length such that L d1 Can be equal to L d2 , that is, L d1=L d2 However, in an alternative embodiment, L d1 May not be equal to L d2 , that is, L d1 ≠L d2 In addition, in an embodiment, the first linearly arranged light generating device and the second linearly arranged light generating device may respectively have a first cross-sectional size D d1 and the second cross-sectional dimension D d2 . First section dimension D d1 and the second cross-sectional dimension D d2 The maximum value of can be independently selected from the range of ≤50 mm, for example, from the range of ≤25 mm, such as from the range of ≤15 mm, in particular from the range of ≤10 mm, more particularly from the range of ≤5 mm. In addition, in an embodiment, the first cross-sectional dimension D d1 and the second cross-sectional dimension D d2 The minimum value of may be independently selected from a range of ≥1 mm, for example, from a range of ≥2 mm, such as from a range of ≥5 mm, in particular from a range of ≥10 mm. Therefore, in an embodiment, the first linearly arranged light generating device and the second linearly arranged light generating device may have a selected cross-sectional size such that D d1 Can be equal to D d2 , that is, D d1 =D d2 However, in an alternative embodiment, D d1 May not be equal to D d2 , that is, D d1 ≠D d2 .

[0011] Additionally or alternatively, the first linear arrangement of light generating devices and the second linear arrangement of light generating devices may have an aspect ratio, which may be defined as the length of the linear arrangement of light generating devices in a cross-sectional dimension, i.e., a first aspect ratio L d1 / D d1 and the second aspect ratio L d2 / D d2 In an embodiment, the aspect ratio L d1 / D d1 and L d2 / D d2 The value of may be independently selected from a range of ≥3, such as a range of ≥4, particularly a range of ≥5, such as a range of ≥10, such as a range of ≥50, particularly a range of ≥100, more particularly a range of ≥1000. Therefore, in an embodiment, the first aspect ratio L d1 / D d1 and the second aspect ratio L d2 / D d2 However, in an alternative embodiment, the first aspect ratio Ld1 / D d1 and the second aspect ratio L d2 / D d2 May not be equal. In addition, the light generating device may be configured to generate device light. In particular, the light generating device of the first linear arrangement may be configured to generate the first device light. Similarly, the light generating device of the second linear arrangement may be configured to generate the second device light.

[0012] As already stated, in embodiments, the pivotable component may include a first pivotable component and a second pivotable component. The first and second pivotable components may be configured to be pivotable relative to each other. Thus, in embodiments, the first pivotable component and the second pivotable component may have a variable absolute orientation and / or relative orientation relative to each other.

[0013] In particular, in an embodiment, the first pivotable member and the second pivotable member can rotate around the axis of rotation. The first pivotable member can have an extension axis. For example, the mutual angle β1 between the first pivotable member and the axis of rotation can be, for example, selected from 0° and 90°, but can also be selected from the range of 0-90°. When the mutual angle β1 is 0°, the first pivotable member and the axis of rotation are configured to be parallel. When the mutual angle β1 is 90°, the first pivotable member and the axis of rotation are configured to be orthogonal. The mutual angle β2 between the second pivotable member and the axis of rotation can (also) be, for example, selected from 0° and 90°, but can also be selected from the range of 0-90°. When the mutual angle β2 is 0°, the second pivotable member and the axis of rotation are configured to be parallel. When the mutual angle β2 is 90°, the second pivotable member and the axis of rotation are configured to be orthogonal. In particular, in an embodiment, the two mutual angles are the same. Assuming that the mutual angles between the first pivotable component and the rotation axis and between the second pivotable component and the rotation axis are both 0°, the first pivotable component, the rotation axis and the second pivotable component can be configured to be parallel. Assuming that the mutual angles between the first pivotable component and the rotation axis and between the second pivotable component and the rotation axis will be 90°, both the first pivotable component and the second pivotable component can be configured to be orthogonal to the rotation axis.

[0014] Optionally, at least one of the pivotable components may additionally extend along the axis O of the respective pivotable component. Lx The upper portion can be pivotable, for example, within an angular range of 180°.

[0015] Further, in an embodiment, the first pivotable member may be configured to support a first linear arrangement of light generating devices. Likewise, in an embodiment, the second pivotable member may be configured to support a second linear arrangement of light generating devices. In this way, the first linear arrangement of light generating devices and the second linear arrangement of light generating devices may be configured to pivot relative to each other.

[0016] In an embodiment, the first pivotable member and the second pivotable member may be configured to be perpendicular to each other in length, that is, the first pivotable member and the second pivotable member are perpendicular to the central support element in length. In other embodiments, the first pivotable member and the second pivotable member may be configured to be parallel to each other in length. In other embodiments, the first pivotable member and the second pivotable member may be configured to be diagonal to each other in length. Further, in an embodiment, the first pivotable member and the second pivotable member may be configured at a symmetrical angle relative to each other and the surface to be illuminated. However, in an embodiment, the first pivotable member and the second pivotable member may also be configured to be at an asymmetrical angle relative to each other and the surface to be illuminated. Therefore, in an embodiment, the first pivotable member and the second pivotable member may be pivoted relative to each other during operation, so that the light generating system can be switched between multiple different configurations.

[0017] Further, in an embodiment, the light generating device of the first linear arrangement may include one or more first solid-state light sources. Similarly, in an embodiment, the light generating device of the second linear arrangement may include one or more first solid-state light sources. The number of the first solid-state light source and / or the second solid-state light source may be individually selected from the range of 1-2000, such as selected from the range of 2-2000, such as selected from the range of 10-1000, particularly selected from the range of 25-500, more particularly selected from the range of 50-200. Therefore, in an embodiment, the amount of the first solid-state light source may be equal to the amount of the second solid-state light source. However, in other embodiments, the amount of the first solid-state light source may not be equal to the amount of the second solid-state light source. Further, the first and second solid-state light sources may be solid-state light sources selected from a group including LEDs, OLEDs, PLEDs and other solid-state light sources (also see below) in an embodiment.

[0018] Furthermore, in embodiments, the light generating system may have at least a first operating mode. In the first operating mode of the light generating system, in embodiments, the first device light and the second device light may differ in color point (see also below). In embodiments, the light generating system may have a plurality of operating modes.

[0019] In an embodiment, the first linearly arranged light generating device may be configured to generate a first linear beam of first device light. Therefore, in an embodiment, the first linearly arranged light generating device may include a plurality of linearly arranged first solid-state light sources. Furthermore, the first solid-state light sources may be configured to generate first solid-state light source light. In an embodiment, the first device light may include at least a portion of the first solid-state light source light of one or more of the first solid-state light sources. In particular, in an embodiment, the first device light may include at least a portion of the first solid-state light source light of one or more of the linearly arranged first solid-state light sources.

[0020] In an embodiment, the second linearly arranged light generating device may be configured to generate a second linear beam of second device light. Therefore, in an embodiment, the second linearly arranged light generating device may include a plurality of linearly arranged second solid-state light sources. In addition, the second solid-state light source may be configured to generate second solid-state light source light. In an embodiment, the second device light may include at least a portion of the second solid-state light source light of one or more of the second solid-state light sources. In particular, in an embodiment, the second device light may include at least a portion of the second solid-state light source light of one or more of the linearly arranged second solid-state light sources.

[0021] A linear beam of device light may be defined as a linear beam of device light having a light distribution that is extended such that the beam extends in a length direction at least twice or three times more than the light extending in a transverse direction.

[0022] Further, in an embodiment, one or more of the first linearly arranged light generating device and the second linearly arranged light generating device may include one or more of the following: (i) an LED filament, (ii) an LED strip, and (iii) an elongated light guiding element including a linearly arranged light output coupling component. Thus, in an embodiment, the first linearly arranged light generating device may include one or more of the following: (i) an LED filament, (ii) an LED strip, and (iii) an elongated light guiding element including a linearly arranged light output coupling component. In particular, in an embodiment, the first linearly arranged light generating device may include an LED filament. In an alternative embodiment, the first linearly arranged light generating device may include an LED strip. In yet another alternative embodiment, the first linearly arranged light generating device may include an elongated light guiding element, the elongated light guiding element including a linearly arranged light output coupling component. The second linearly arranged light generating device may include one or more of the following that are substantially the same as the first linearly arranged light generating device: (i) an LED filament, (ii) an LED strip, and (iii) an elongated light guiding element (including a linearly arranged light output coupling component). However, in an embodiment, the second linear arrangement of light generating devices may include one or more of the following that are substantially different from the first linear arrangement of light generating devices: (i) LED filaments, (ii) LED strips, and (iii) elongated light guide elements (including linearly arranged light coupling output components) (functionally coupled to the light source).

[0023] In particular, the LED filament may be configured to provide LED filament light. The term "LED filament light" may refer to the light of the LED filament during operation of the LED filament. In an embodiment, the LED filament may include a plurality of light emitting diodes (LEDs), in particular the LEDs are arranged in a linear array.

[0024] The linear array can be a 1D or 2D array of n*m LEDs, wherein n in an embodiment can be selected from the range of 1-4, for example from the range of 1-3, such as from the range of 1-2 (for example in Example 1 or Example 2), and m can be selected from a range greater than n, for example in particular from a range of at least 4 (when n<4), such as from a range of at least 6, for example from a range of at least 8.

[0025] In addition, the LEDs may be arranged to emit, for example, LED light of different colors or spectral power distributions. In embodiments, two or more LEDs may be configured to provide light having substantially the same spectral power distribution. Even more particularly, in embodiments, all LEDs may be configured to provide light having substantially the same spectral power distribution. In other embodiments, two or more LEDs may be configured to provide light having different spectral power distributions.

[0026] In an embodiment, the LED filament may have a length L and a width W, in a specific embodiment, L ≥ 5 W. The LED filament may be arranged in a straight configuration or a non-straight configuration, for example a meandering configuration, a (2D or 3D) spiral configuration or a helical configuration.

[0027] In a particular embodiment, the LEDs may be arranged on an (elongated) carrier (e.g. a substrate). In an embodiment, the (elongated) carrier may be rigid (e.g. made of polymer, glass, quartz, metal or sapphire) or flexible (e.g. made of polymer or metal (e.g. film or foil)).

[0028] In case the carrier comprises a first main surface and an opposite second main surface, the LED is arranged on at least one of these surfaces. In an embodiment, the carrier may be light reflective, in particular reflective for the filament. In an embodiment, the carrier may be light transmissive, such as translucent, and in a specific embodiment transparent.

[0029] In an embodiment, the LED filament may include an encapsulant that at least partially covers at least a portion of the total number of LEDs (of the plurality of LEDs). In a particular embodiment, the encapsulant may also at least partially cover at least one of the first major surface or the second major surface.

[0030] The encapsulant may comprise a polymer material which in embodiments may be flexible, such as silicone. In embodiments, the encapsulant may comprise a resin.

[0031] In an embodiment, the encapsulant may include one or more of a luminescent material and a light scattering material. One or more of the luminescent material and the light scattering material may be embedded in an encapsulation material (such as a polymer material). The luminescent material may be configured in particular to convert the LED light at least partially into converted light. The luminescent material may also be indicated as a "phosphor". The luminescent material may include a phosphor (e.g., an inorganic phosphor) and / or quantum dots or rods.

[0032] Thus, in certain embodiments, LED filament light may include one or more of LED light and converted light ("luminescent material light").

[0033] In an embodiment, an LED filament may include multiple sub-filaments.

[0034] As described above, in embodiments, the LED filament may include a plurality of light emitting diodes. However, in the context of an LED filament, the term LED may also refer to a solid-state light source (generally). Thus, the LED filament may include one or more of an LED, a laser diode, and a superluminescent diode. In particular, the LED filament includes a plurality of light emitting diodes (LEDs).

[0035] In an embodiment, the LED strip may comprise a plurality of LEDs (see also below). The LED strip may be flexible. Further, in an embodiment, the first and / or second linearly arranged light generating device may comprise a plurality of LED strips. For example, n LED strips may be applied. In particular, the LED strip may comprise a flexible support portion configured to support the plurality of LEDs and comprising electrical conductors for electrically connecting the LEDs to a power supply.

[0036] A light guide element comprising linearly arranged light outcoupling means may in particular be an elongated light guide comprising outcoupling elements at its surface and / or in the volume of the light guide material. The light guide material is in particular a light-transmitting material. In particular, the material has a light transmittance in the range of 50%-100%, in particular in the range of 70%-100%, for light having a wavelength selected from the visible wavelength range. Here, the term "visible light" in particular relates to light having a wavelength selected from the range of 380-780 nm.

[0037] The transmittance (or light transmittance) can be determined by providing light of a specific wavelength having a first intensity to a light-transmitting material under vertical irradiation, and correlating the intensity of the light at that wavelength measured after transmission through the material with the first intensity of light provided to the material at the specific wavelength (see also E-208 and E-406 of CRC Handbook of Chemistry and Physics, Vol. 69, 1088-1989).

[0038] In specific embodiments, a material can be considered to be transmissive when the transmittance of radiation at a certain wavelength or wavelength range (especially within the wavelength or wavelength range of radiation generated by a radiation source as described herein) through a 1 mm thick material layer, especially even through a 5 mm thick material layer (in the case of vertical radiation using said radiation) is at least about 20%, for example at least 40%, such as at least 60%, for example in particular at least 80%, for example at least about 85%, for example even at least about 90%.

[0039] The light-transmitting material has light-guiding or wave-guiding properties. Therefore, the light-transmitting material is also referred to herein as a wave-guiding material or a light-guiding material. The light-transmitting material will typically have (some) transmittance of one or more of (N)UV light, visible light and (N)IR radiation (e.g., at least visible light in an embodiment) in a direction perpendicular to the length of the light-transmitting material. In the absence of an activator (dopant) such as trivalent cerium, the internal transmittance in the visible light may be close to 100%.

[0040] For example, the transmittance of the light-transmitting material for one or more luminescence wavelengths may be at least 80% / cm, such as at least 90% / cm, even more particularly at least 95% / cm, such as at least 98% / cm, such as at least 99% / cm. This means that, for example, under vertical illumination with radiation having a selected luminescence wavelength (e.g. corresponding to the wavelength of the emission maximum of the luminescence of the luminescent material of the light-transmitting material), the light-transmitting material of the light-transmitting material is 1 cm 3 A cube-shaped block of light-transmitting material will have a transmittance of at least 95%.

[0041] Here, the values ​​of the transmittance refer in particular to the transmittance without taking into account the Fresnel losses at interfaces (with, for example, air). The term "transmittance" therefore refers in particular to the internal transmittance. For example, by measuring the transmittance of two or more bodies with different widths (over which the transmittance is measured), the internal transmittance can be determined. Based on such measurements, the contribution of the Fresnel reflection losses and (therefore) the internal transmission can then be determined. Therefore, in particular, the values ​​of the transmittance indicated in this document neglect the Fresnel losses.

[0042] In an embodiment, an anti-reflective coating may be applied to the light emitter to suppress Fresnel reflection losses (during the light coupling process).

[0043] In addition to the high transmittance of the wavelength of interest, the scattering of this wavelength may be particularly low. Therefore, the mean free path of the wavelength of interest, considering only the scattering effects (thus, not considering possible absorption (due to the high transmittance, the absorption should be low anyway)), may be at least 0.5 times the body length, such as at least the body length, such as at least twice the body length. For example, in an embodiment, the mean free path considering only the scattering effects may be at least 5 mm, such as at least 10 mm. The wavelength of interest may in particular be the wavelength at the maximum emission of the luminescence of the luminescent material. The term "mean free path" is in particular the average distance that a light ray will travel before experiencing a scattering event, which will change the direction of propagation of the light ray.

[0044] In an embodiment, the element comprising a light transmissive material may consist essentially of the light transmissive material. In a particular embodiment, the element comprising a light transmissive material may be a light transparent element.

[0045] In particular, the light-transmitting element (such as a light-transparent element) may in an embodiment have an absorption length and / or a scattering length which is at least the length (or thickness) of the light-transmitting element, such as at least twice the length of the light-transmitting element. The absorption length may be defined as a length over which the intensity of the light along the propagation direction decreases by 1 / e due to absorption. Similarly, the scattering length may be defined as a length along the propagation direction along which the light is lost due to scattering and thus decreases to 1 / e. Here, the length may therefore particularly refer to the distance between a primary face and a secondary face of the light-transmitting element, wherein the light-transmitting material is arranged between the primary face and the secondary face.

[0046] The light guide element comprising the linearly arranged light outcoupling components may be functionally coupled to a light source configured to generate light source light. The light guide element (such as its primary face or its secondary face) may be configured to be in light receiving relationship with the light source. In particular, such a light source may be a solid state light source.

[0047] The term "light receiving relationship" and similar terms may mean that an item can receive light from a light source (such as a light generating device or a light generating element or a light generating system) during operation of the light source. Therefore, the item can be arranged downstream of the light source. An optical device can be arranged between the light source and the item. For example, in the context of light propagation, the terms "upstream" and "downstream" may particularly relate to the arrangement of items or features relative to the propagation of light from a light generating element (here particularly a light generating system), wherein, relative to a first position in a light beam from the light generating element, a second position in the light beam that is closer to the light generating element (than the first position) is "upstream", and a third position in the light beam that is farther away from the light generating element (than the first position) is "downstream". For example, instead of the term "light generating element", the term "light generating device" may also be applied.

[0048] Furthermore, in an embodiment, the first and / or second linearly arranged light generating means may comprise a diffuser.

[0049] In an embodiment, in a first operating mode of the light generating system, the first color point of the first device light and the second color point of the second device light may differ by at least 0.03 for u' and / or may differ by at least 0.03 for v' (see also below).

[0050] By means of the present system, light having at least two different colours or shades may be provided. Additionally or alternatively, light having a colour gradient may be provided.

[0051] In an embodiment, in a first operating mode of the light generating system, the first device light may have a first color point and the second device light may have a second color point. In particular, in an embodiment, the first color point of the first device light and the second color point of the second device light may differ by at least 0.03 for u' and / or by at least 0.03 for v', such as by at least 0.05 for u' and / or v', such as by at least 0.1 for u' and / or v', and in particular by at least 0.25 for u' and / or v'. Thus, in an embodiment, the first color point may have the same value for u' as the second color point, but differ by at least 0.03 for v'. Likewise, in other embodiments, the first color point may have the same value for v' as the second color point, but differ by at least 0.03 for u'. In yet another embodiment, the first color point and the second color point may differ by at least 0.03 for both u' and v'. For example, in an embodiment, the first device light may be blue light, and the second device light may be green light. Furthermore, u' and v' may be color coordinates of light in the CIE 1976 UCS (Uniform Chromaticity Scale) diagram.

[0052] In an embodiment, the pivotable member may include a pivotable member length L p Furthermore, in an embodiment, the pivotable components may include a plurality of pivotable members perpendicular to the length L of the corresponding pivotable components. p Maximum cross-sectional dimension D p In particular, in the embodiment, L p / D p ≥5. Therefore, in certain embodiments, the pivotable member may include a pivotable member length L p and the maximum cross-sectional dimension Dd, where L p / D p ≥5. In particular, in the embodiment, the length L of the pivotable component p It can be selected from the range of 5-150 cm. In addition, in an embodiment, the maximum cross-sectional dimension can be selected from the range of 2-50 mm.

[0053] The pivotable component length may be defined as the length of the largest side of the pivotable component. The pivotable component length may be selected individually for the pivotable component. Thus, in an embodiment, the first pivotable component may have a first pivotable component length L p1 Likewise, the second pivotable member may have a second pivotable member length L p2 In an embodiment, the length L of the pivotable member p It may be selected from the range of 5-150 cm, for example from the range of 10-100 cm, such as from the range of 25-80 cm, in particular from the range of 30-60 cm.

[0054] In an embodiment, the pivotable components may include a plurality of pivotable components perpendicular to the length L of the corresponding pivotable components. p Maximum cross-sectional dimension D p The maximum cross-sectional dimensions may be selected individually for the pivotable components. Thus, in an embodiment, the first pivotable component may have a first maximum cross-sectional dimension D p1 Likewise, the second pivotable member may have a second maximum cross-sectional dimension D p2 In the embodiment, the maximum cross-sectional dimension D p It may be selected from the range of 2-50 mm, such as from the range of 2-30 mm, like from the range of 5-20 mm, in particular from the range of 8-15 mm.

[0055] Furthermore, in the embodiment, for each pivotable component, the pivotable component length L p and maximum cross-sectional dimension D p The ratio L p / D p It may be individually selected from a range of ≥3, for example from a range of ≥4, in particular from a range of ≥5, such as from a range of ≥10, for example from a range of ≥50, in particular from a range of ≥100, more particularly from a range of ≥1000.

[0056] Additionally or alternatively, in an embodiment, the first (and / or second) linearly arranged light generating device may be arranged at a length L of the corresponding pivotable member. p at least 50% of the length L of the pivotable member, such as pAt least 60% of the length of the first (and / or second) device light is emitted, such as at least 70%, in particular at least 80%, more particularly at least 90%, such as at least 95% (including more than 100%). Therefore, in an embodiment, the first (and / or second) linearly arranged light generating device can emit the first (and / or second) device light over at least a portion of the entire length of the corresponding pivotable component. In particular, in an embodiment, the first (and / or second) linearly arranged light generating device can emit the first (and / or second) device light over the entire length of the corresponding pivotable component.

[0057] As already mentioned, in embodiments, the first pivotable component and the second pivotable component may have a mutual orientation on the pivot axis Op at a variable pivot angle α. In particular, in embodiments, the difference between the minimum pivot angle α1 and the maximum pivot angle α2 may be at least 45°, such as at least about 90°. Additionally or alternatively, in embodiments, the difference between the minimum pivot angle α1 and the maximum pivot angle α2 may be selected from the range of 90-360°, or even 45-360°. Thus, in particular embodiments, the first pivotable component and the second pivotable component may have a mutual orientation on the pivot axis Op at a variable pivot angle α, wherein the difference between the minimum pivot angle α1 and the maximum pivot angle α2 may be at least 45°.

[0058] The light generating system may be configured to generate system light. In an operation mode of the light generating system, the system light may include device light of at least one of the light generating devices. In particular, in an embodiment, the system light may include at least one of a first device light and a second device light.

[0059] The pivot axis Op may be defined as an imaginary line perpendicular to the direction in which system light propagates out of the light generating system.The pivot axis Op may be centered between the first pivotable component and the second pivotable component.

[0060] In an embodiment, the first pivotable component and the second pivotable component may have a mutual orientation on the pivot axis Op such that a variable pivot angle α may exist. The variable pivot angle α may have a minimum pivot angle α1 and a maximum pivot angle α2. In an embodiment, the minimum pivot angle α1 may be selected from the range of 0-315°, such as from the range of 45-270°, such as from the range of 90-180°. Therefore, the minimum pivot angle α1 may be ≤315°, such as ≤180°, such as ≤90°, in particular ≤45°, more particularly ≤15°, including 0°. In an embodiment, the maximum pivot angle α2 may be selected from the range of 45-360°, such as from the range of 90-315°, such as from the range of 180-270. Therefore, the maximum pivot angle α2 may be ≥45°, such as ≥90°, such as ≥180°, in particular ≥270°, including 360°.

[0061] In addition, in an embodiment, the difference between the minimum pivot angle α1 and the maximum pivot angle α2 can be at least 45°, such as at least 60°, such as at least 90°, in particular at least 120°, and more in particular at least 180°. In an embodiment, the difference between the minimum pivot angle α1 and the maximum pivot angle α2 can be selected from the range of 45-360°, such as from the range of 90-330°, such as from the range of 150-300°, in particular from the range of 180-270°. For example, in a specific embodiment, the variable pivot angle α can vary between a minimum pivot angle α1 of 180° and a maximum pivot angle α2 of 225°, and thus, the variable pivot angle α can vary over a range of 45° here. In yet another example, the variable pivot angle α can vary between a minimum pivot angle α1 of 0° and a maximum pivot angle α2 of 90°, and thus, the variable pivot angle α can vary over a range of 90° here.

[0062] In an embodiment, at least one of the first linear arrangement of light generating devices and the second linear arrangement of light generating devices may be configured to generate colored device light. In a specific embodiment, both the first linear arrangement of light generating devices and the second linear arrangement of light generating devices may be configured to generate colored device light. In other embodiments, the first linear arrangement of light generating devices may be configured to generate colored device light, while the second linear arrangement of light generating devices may not be configured to generate colored device light. The colored device light may be, for example, violet light, blue light, blue-green light, green light, yellow light, orange light, or red light.

[0063] The terms "violet light" or "violet emission" and similar terms may particularly relate to light having a wavelength in the range of about 380-440nm. In a specific embodiment, the violet light may have a centroid wavelength in the range of 380-440nm.

In a specific embodiment, the orange light may have a centroid wavelength in the range of 590-620 nm. The terms "red light" or "red emission" and similar terms may particularly relate to light having a wavelength in the range of about 620-750 nm. In a specific embodiment, the red light may have a centroid wavelength in the range of 620-750 nm. The terms "cyan light" or "cyan emission" and similar terms may particularly relate to light having a wavelength in the range of about 490 nm to 520 nm. In a specific embodiment, the cyan light may have a centroid wavelength in the range of 490-520 nm. The terms "amber light" or "amber emission" and similar terms may particularly relate to light having a wavelength in the range of about 585-605 nm, such as about 590-600 nm. In a specific embodiment, the amber light may have a centroid wavelength in the range of 585 nm to 605 nm. The phrase "light having one or more wavelengths within a wavelength range" and similar phrases may indicate, among other things, that the indicated light (or radiation) has a spectral power distribution having at least one intensity or multiple intensities at the one or more wavelengths within the indicated wavelength range. For example, a blue emitting solid-state light source will have a spectral power distribution having intensities at one or more wavelengths within the wavelength range of 440-495 nm. The terms "visible", "visible light" or "visible emission" refer to light having a wavelength within the range of about 380-780 nm.

[0064] Further, in an embodiment, at least one of the first linearly arranged light generating device and the second linearly arranged light generating device may be configured to generate device light having a controllable spectral power distribution. In an embodiment, the first linearly arranged light generating device light may include a first spectral power distribution. Similarly, the second linearly arranged light generating device light may include a second spectral power distribution. In a specific embodiment, both the first linearly arranged light generating device and the second linearly arranged light generating device may be configured to generate device light having a controllable spectral power distribution. In other embodiments, the first linearly arranged light generating device may be configured to generate device light having a controllable first spectral power distribution, while the second linearly arranged light generating device may be configured to generate device light having a fixed second spectral power distribution.

[0065] Furthermore and as mentioned earlier, in embodiments, the light generating system may comprise a control system (see also below). In embodiments, the control system may be configured to control a controllable spectral power distribution of device light of at least one of the first linear arrangement of light generating devices and the second linear arrangement of light generating devices.

[0066] In embodiments, the control system may be included in the arrangement. In other embodiments, the control system may be configured external to the arrangement and may be functionally coupled thereto (particularly to a linear arrangement of light generating means). In embodiments, the light generating system may comprise a control system directly coupled to the light generating means. However, in embodiments, the light generating system may be functionally coupled to an external control system.

[0067] In an embodiment, the light generating system may include a second operating mode. In particular, in the second operating mode of the light generating system, the spectral power distribution of at least one of the first device light and the second device light is along the pivotable member length L of the corresponding pivotable member. p The color points of at least a portion of the image may be different in space.

[0068] In an embodiment, in the second operating mode of the light generating system, the spectral power distribution of both the first device light and the second device light is 100° along the pivotable member length L of the respective pivotable member. p In other embodiments, in the second operating mode of the light generating system, only one of the first device light and the second device light is rotatable along the pivotable member length L of the corresponding pivotable member. p The color points of at least a portion of the image may be different in space.

[0069] In an embodiment, the first (and / or second) device light is arranged along the pivotable member length L of the corresponding pivotable member. pAt least a portion of may have two or more different colors. For example, in an embodiment, the first (and / or second) device light may be arranged along the pivotable member length L of the corresponding pivotable member. p In other embodiments, the first (and / or second) device light may be provided along the pivotable member length L of the corresponding pivotable member. p At least a portion of the first (and / or second) device light may have two or more colors in a regularly alternating pattern. In further embodiments, the first (and / or second) device light may be arranged along the pivotable member length L of the corresponding pivotable member. p At least a portion of the first (and / or second) device light may have two or more colors in an irregular alternating pattern. In further embodiments, the first (and / or second) device light may be arranged along the pivotable member length L of the corresponding pivotable member. p Thus, in an embodiment, the first (and / or second) device light may be pivotable along the pivotable member length L of the corresponding pivotable member. p At least a portion of the light generating system has a color gradient. These described embodiments may be viewed as examples of different operating modes of a light generating system as discussed above and further discussed below.

[0070] In an embodiment, the light generating system may be configured to generate system light. In particular, in the operation mode of the light generating system, the system light may include a device light of at least one of the light generating device. More specifically, in an embodiment, in the operation mode of the light generating system, the system light may include a device light of at least one of a first device light and a second device light. Further, in an embodiment, the light generating system may include a control system configured to control the device light. In particular, in an embodiment, the control system may be configured to control the device light according to one or more of an input signal of a user interface, a sensor signal of a sensor, and a timer. Therefore, in a specific embodiment, the light generating system may be configured to generate system light, wherein in the operation mode of the light generating system, the system light may include a device light of at least one of a first device light and a second device light, wherein the light generating system may further include a control system configured to control the device light according to one or more of an input signal of a user interface, a sensor signal, and a timer.

[0071] This may be advantageous as it may enable the light generating system to automatically adjust light settings based on detection of the relative orientation (eg, opening angle) and absolute orientation (vertical vs. horizontal) of the first and second linearly arranged light generating devices.

[0072] As described above, the light generating system may have a first and a second operating mode. However, in an embodiment, the light generating system may have additional or alternative operating modes. For example, in the operating mode of the light generating system, the system light may include a device light of at least one of the light generating devices. In particular, in an embodiment, in the operating mode of the light generating system, the system light may include a device light of at least one of the first device light and the second device light. Therefore, in an embodiment, the light generating system may include an operating mode that includes the first linearly arranged light generating device or the second linearly arranged light generating device being turned on. In another operating mode, both the first linearly arranged light generating device and the second linearly arranged light generating device may be turned on. In another operating mode, both the first linearly arranged light generating device and the second linearly arranged light generating device may be turned off.

[0073] Furthermore, in an embodiment, the light generating system may include a control system (see also above and below) configured to control the device light according to one or more input signals. Such input signals may be, for example, one or more of a user interface, a motion sensor, a distance sensor, an integrated orientation sensor, a timer, and an input signal generated by a mobile device controlled by a user.

[0074] The sensor can detect the absolute orientation of the linearly arranged light generating device (e.g., vertical or horizontal orientation), the relative orientation of the linearly arranged light generating device (e.g., variable pivot angle), and the distance of the linearly arranged light generating device to the effect surface (e.g., wall or ceiling). Based on such detection, the sensor can send a signal to the control system, which in turn can control the device light.

[0075] In an embodiment, the sensor as discussed above may be configured to be attached or engaged into the light generating device. However, in other embodiments, the sensor may also be a sensor located outside the light generating device but functionally coupled (such as attached or integrated) in the pivotable component. In further embodiments, the sensor may be configured elsewhere in the arrangement, or even external to the arrangement.

[0076] In particular embodiments, each pivotable component may include a sensor, such as an accelerometer, configured to generate an orientation signal.

[0077] The term "sensor" may also refer to a plurality of (different) sensors.

[0078] In an embodiment, the sensor may include one or more sensors selected from the group of an ambient light sensor (e.g., for sensing light in a space such as a room), an outdoor light sensor, a temperature sensor, a proximity sensor, a motion sensor, and the like.

[0079] The term "timer" may refer to a clock and / or a predetermined timing scheme.

[0080] The term "control" and similar terms refer in particular at least to determining the behavior of an element or supervising the operation of an element. Therefore, herein, "control" and similar terms may, for example, refer to applying behavior (determining the behavior or supervising the operation of an element) to an element, such as measuring, displaying, actuating, opening, moving, changing temperature, etc. In addition, the term "control" and similar terms may additionally include monitoring. Therefore, the term "control" and similar terms may include applying behavior on an element, and also include applying behavior on an element and monitoring the element. The control of an element may be accomplished using a control system, which may also be represented as a "controller". Therefore, the control system and the element may be functionally coupled at least temporarily or permanently. The element may include the control system. In an embodiment, the control system and the element may not be physically coupled. Control may be accomplished by wired and / or wireless control. The term "control system" may also refer to a plurality of different control systems, which are particularly functionally coupled, and in the plurality of different control systems, for example, one control system may be a master control system, and one or more other control systems may be slave control systems. The control system may include a user interface or may be functionally coupled to a user interface.

[0081] The control system may also be configured to receive and execute instructions from a remote control. In an embodiment, the control system may be controlled via an application (App) on a device, such as a portable device such as a smartphone or I-phone, tablet computer, etc. Thus, the device is not necessarily coupled to the lighting system, but may be (temporarily) functionally coupled to the lighting system.

[0082] Thus, in an embodiment, the control system may (also) be configured to be controlled by an application on a remote device. In such an embodiment, the control system of the lighting system may be a slave control system or a controller in slave mode. For example, the lighting system may be identified with a code, in particular a unique code of the corresponding lighting system. The control system of the lighting system may be configured to be controlled by an external control system, which has access to the lighting system based on knowledge of the (unique) code (e.g. input by a user interface with an optical sensor such as a QR code reader). The lighting system may also include means for communicating with other systems or devices, e.g. based on Bluetooth, Thread, WIFI, LiFi, ZigBee, BLE or WiMAX, or another wireless technology.

[0083] The system, or device, or apparatus may perform actions in a "mode" or "operating mode" or "mode of operation". The term "operating mode" may also be indicated as a "control mode". Similarly, in a method, actions or phases or steps may be performed in a "mode" or "operating mode" or "mode of operation". This does not exclude that the system, or device, or apparatus may also be adapted to provide another control mode, or a plurality of other control modes. Similarly, this may not exclude that one or more other modes may be executed before and / or after the execution of a mode.

[0084] However, in an embodiment, the control system may be available, i.e. adapted to at least provide a control mode. Assuming that other modes are available, the selection of such modes may in particular be performed via a user interface, but other options (e.g. performing a mode in dependence on a sensor signal or a (time) scheme) are also possible. In an embodiment, an operating mode may also refer to a system, or a device, or an apparatus that can only be operated in a single operating mode (i.e. "on" but without further adjustability).

[0085] As described above, in an embodiment, the control system may be configured to control the device light according to the variable pivot angle α. This may be advantageous, for example, when the light generating system may be used as part of a vertical wall flusher. The intensity (e.g., brightness or color gradient) of the light output may be adjusted according to the variable pivot angle α of the first and second linearly arranged light generating devices pivotably arranged relative to each other. Therefore, in an embodiment, the control system may be configured to increase or decrease the brightness of the first (and / or second) linearly arranged light generating device when the variable pivot angle α increases. However, the control system may also be configured to increase or decrease the brightness of the first (and / or second) linearly arranged light generating device when the variable pivot angle α decreases. In other embodiments, the control system may be configured to change the color (gradient) of the first (and / or second) linearly arranged light generating device in response to a change in the variable pivot angle α.

[0086] In another example, when the light generating system can be used as a ceiling light structure (e.g. above a table), a productive light setting can be activated by the control system when all linearly arranged light generating devices are directed downwards. Additionally or alternatively, an atmosphere creating setting can be activated for the linearly arranged light generating devices directed upwards to the ceiling (possibly combined with a productive light setting directed downwards to the table to obtain a dual function mode). Other examples of light settings depending on the variable pivot angle α are also possible.

[0087] Therefore, the light generating system according to the present invention may have the following characteristics: control of the system light according to the variable pivot angle (α) is related to at least one of the following items: i) the intensity level of at least one of the first device light and the second device light; ii) the intensity ratio of the first device light and the second device light; iii) the emission spectrum of at least one of the first device light and the second device light; and iv) the difference in color, color temperature or correlated color temperature between the first device light and the second device light.

[0088] Furthermore, in an embodiment, the control system may be configured to control the device light according to the distance to the surface illuminated by the light generating device. This may be advantageous because it may allow the light generating system to adjust the light setting according to its distance to, for example, a wall. In this way, a lamp including the light generating system may be able to provide improved optical performance in different orientations.

[0089] In an embodiment, the light generating system may be configured to face the surface to be illuminated. For example, in an embodiment, the light generating system may be configured to face a wall. In other embodiments, the light generating system may be configured to face a floor or a ceiling. In other embodiments, the light generating system may be configured to face a horizontal work surface, such as the surface of a round table, the surface of a trimmer, or the surface of a square table. The light generating system may also be configured to face any other surface, such as the surface of an object. In an embodiment, the control system may include a sensor capable of detecting the distance between the light generating system and the surface to be illuminated. In particular, the control system may be configured to control the intensity or color of the device light in response to a change in distance. So, in an embodiment, the control system may be configured to increase or decrease the brightness of the first (and / or second) linearly arranged light generating device when the distance to the surface illuminated by the light generating device increases. However, the control system may also be configured to increase or decrease the brightness of the first (and / or second) linearly arranged light generating device when the distance to the surface illuminated by the light generating device decreases. In other embodiments, the control system may be configured to change the color (gradient) of the first (and / or second) linear arrangement of light generating devices in response to a change in the distance to the surface illuminated by the light generating devices.

[0090] In an embodiment, the control system may be able to detect the distance between the light generating device and the surface illuminated by the light generating device. For example, the control system may include a sensor for detecting the distance between the light generating device and the surface illuminated by the light generating device. In particular, the sensor can detect the distance from the light generating device to the wall or to the ceiling. Then, such a sensor signal can be converted into an option for the light setting suitable for the distance, wherein the light output of the light generating device can be adjusted accordingly. In an embodiment, the detection of a short distance can lead to a decrease in the light output (e.g., brightness or color gradient). In other embodiments, the detection of a short distance can lead to an increase in the light output (e.g., brightness or color gradient). Similarly, in the case of a long distance between the light generating device and the illuminated surface, the light output (e.g., brightness or color gradient) can be adjusted. Thus, in an embodiment, the light generating system can use a sensor to detect its distance to the surface. However, in an embodiment, the control system of the light generating system can also receive a signal by means of an external smart phone sensor or by using input from a user.

[0091] Further, in an embodiment, the light generating system may include a baffle element. In particular, in an embodiment, the baffle element may be functionally coupled to at least one of the pivotable components. Further, in an embodiment, the baffle element may be at least partially configured between the first linearly arranged light generating device and the second linearly arranged light generating device. Still further, in an embodiment, the baffle element may be configured to limit the overlap of light beams of the first device light and the second device light. Therefore, in a specific embodiment, the light generating system may include a baffle element, which is functionally coupled to at least one of the pivotable components, is at least partially configured between the first linearly arranged light generating device and the second linearly arranged light generating device, and is configured to limit the overlap of light beams of the first device light and the second device light.

[0092] Therefore, in an embodiment, the light generating system comprises a unit comprising the light generating device, the pivotable part, the central support and the baffle element.

[0093] Inclusion of a baffle element into a light generating system may be beneficial as it may allow a user to separate the light beams of two or more light generating devices. For example, when two light generating devices are configured to generate device lights, each device light having a different color, the baffle element may ensure separation of the light beams of the device lights and may therefore prevent mixing of the colors. The baffle element may also provide the benefit of generating decorative light beam patterns. When a baffle having a patterned shape is used, the baffle may allow partial mixing of the light beams, which may provide a decorative light beam pattern.

[0094] In an embodiment, the light generating system may comprise a baffle element. In an embodiment, the baffle element may be a sheet, a plate or a rod. In particular, the baffle element may be a sheet or a plate of rectangular shape.

[0095] The baffle element may have a length L relative to the pivotable part. p For example, in an embodiment, the baffle element length Lb may be equal to the pivotable member length L p , that is, L b =L p However, in other embodiments, the baffle element length Lb may not be equal to the pivotable member length L p , that is, the baffle element may be longer than the pivotable component length L p Longer or shorter.

[0096] In an embodiment, the baffle element may further have a width selected from the range of 2-50 cm, for example selected from the range of 5-25 cm, such as selected from the range of 5-10 cm. In an embodiment, the baffle element may also have a thickness selected from the range of 2-100 mm, such as selected from the range of 5-50 mm, such as selected from the range of 10-25 mm.

[0097] Further, in an embodiment, the baffle element may be functionally coupled to at least one of the pivotable components. In an embodiment, the baffle element may be functionally coupled to both the first pivotable component and the second pivotable component, i.e., the baffle element may be coupled between the first pivotable component and the second pivotable component (or coupled to a hinge of the first pivotable component and the second pivotable component). In particular, in an embodiment, the baffle element may be at least partially arranged between the first linearly arranged light generating device and the second linearly arranged light generating device.

[0098] Furthermore, in an embodiment, the baffle element may be configured to be pivotable relative to one or more of the first pivotable part and the second pivotable part. Thus, the baffle element is capable of pivoting relative to one or more of the first pivotable part and the second pivotable part on the pivot axis Op. In an embodiment, the baffle element may be pivotable relative to the first (and / or second) linearly arranged light generating device at a baffle pivot angle α. b1 and / or α b2 Pivot. Baffle pivot angle α b1 and / or α b2 It may be selected from the range of 5-355°, such as from the range of 35-315°, such as from the range of 30-270°, in particular from the range of 35-180°, such as from the range of 45-180°.

[0099] In particular, in an embodiment, the baffle element may be configured to limit the overlap of the light beams of the first device light and the second device light. Therefore, in an embodiment, the baffle element may at least partially include a material that may be opaque. In other embodiments, the baffle element may at least partially include a material that can reflect the incident light beam. In an embodiment, the baffle element may at least partially include a material selected from the following group, the group including: metal, polymer material, ceramic material, wood material, glass or 3D printed material. In an embodiment, for example, the first device light may be blue light and the second device light may be yellow light. In such a case, the baffle element may limit the overlap of the blue light beam with the yellow light beam, that is, the baffle element may prevent the light beams from combining into green light.

[0100] Additionally or alternatively, in an embodiment, the baffle element may have a shape selected from the group consisting of a rectangular shape, a triangular shape, a crescent shape, an elliptical shape, and an irregular shape. However, in an alternative embodiment, the baffle element may also have a patterned shape, such as a pattern selected from the group consisting of a sawtooth pattern, a rectangular pattern, a triangular pattern, and a sinusoidal pattern. In such an embodiment, the baffle may be configured to only partially limit the overlap of the light beams of the first linear arrangement of light generating devices and the second linear arrangement of light generating devices. Therefore, in an embodiment, the resulting light incident on the illuminated surface may consist of a pattern of mixed light beams and unmixed light beams.

[0101] In an embodiment, the light generating system may further include a central support element. In particular, in an embodiment, the pivotable components may be configured to be pivotable around the central support element. In addition, the light generating system may include a central support element light generating device. The central support element light generating device may be configured to generate support element device light. Further, in an embodiment, the central support element light generating device may include one or more central support element solid-state light sources. In an embodiment, the central support element may be configured to support the central support element light generating device. Therefore, in a specific embodiment, the light generating system may further include a central support element, and the pivotable components may be configured to be pivotable around the central support element; wherein the light generating system may further include a central support element light generating device, the central support element light generating device being configured to generate support element device light; wherein the central support element light generating device may include one or more central support element solid-state light sources; and wherein the central support element is configured to support the central support element light generating device.

[0102] Hence, in an embodiment, the light generating system comprises a unit comprising the light generating device, the pivotable part and the central support.

[0103] By means of the present system, a light generating system with at least three different light sources can be provided, which can provide the possibility to generate three different colors of light simultaneously. Furthermore, an improved color light gradient can be generated. Additionally or alternatively, the present system can improve the adjustability of the beam angle, beam shape and beam color.

[0104] In an embodiment, the light generating system may include a central support element. In particular, in an embodiment, the central support element may have a support element length L cp . Support element length L cp In an embodiment, the length L of the support element may be selected from the range of 2 cm-10 m, for example, from the range of 10 cm-5 m, such as from the range of 50 cm-3 m, and in particular from the range of 100 cm-1 m. cp can be chosen so that 0.01≤L cp / L p ≤100, such as 0.5≤L cp / L p ≤50, especially 1≤L cp / L p ≤25.

[0105] Furthermore, in an embodiment, the central support element may have a shape selected from the group consisting of: a (semi) cylinder, a (polygonal) prism, a tube, and a rod.

[0106] Furthermore, in embodiments, the pivotable component may be configured to pivot about a central support element.

Further, in an embodiment, the system light may include at least one or more of a first device light, a second device light, and a support element device light. In an embodiment, the central support element light generating device may include one or more central support element solid-state light sources.

[0108] The light generating device may in particular be configured to generate device light. In particular, the light generating device may comprise a light source. The light source may in particular be configured to generate light source light. In embodiments, the device light may consist essentially of the device light. In other embodiments, the device light may consist essentially of converted light source light. In other embodiments, the device light may comprise (unconverted) light source light and converted light source light. The light source light may be converted into luminescent material light with a luminescent material and / or into upconverted light with an upconverter (see also below). The term "light generating device" may also refer to a plurality of light generating devices that may provide device light having substantially the same spectral power distribution. In specific embodiments, the term "light generating device" may also refer to a plurality of light generating devices that may provide device light having different spectral power distributions.

[0109] The term "light source" may in principle relate to any light source known in the art. It may be a conventional (tungsten) bulb, a low-pressure mercury lamp, a high-pressure mercury lamp, a fluorescent lamp, an LED (light emitting diode). In a specific embodiment, the light source comprises a solid-state LED light source (such as an LED or a laser diode (or "diode laser")). The term "light source" may also relate to a plurality of light sources, such as 2-2000 (solid-state) LED light sources. Therefore, the term LED may also refer to a plurality of LEDs.

[0110] Furthermore, in an embodiment, the term "light source" may also refer to a so-called chip-on-board (COB) light source. The term "COB" refers in particular to an LED chip in the form of a semiconductor chip, which is neither encapsulated nor connected, but is directly mounted on a substrate (such as a PCB). Thus, a plurality of light-emitting semiconductor light sources may be arranged on the same substrate. In an embodiment, a COB is a plurality of LED chips that are configured together as a single lighting module.

[0111] The term "light source" may also refer to a chip scale package (CSP). A CSP may include a single solid-state die on which a layer containing a luminescent material is disposed. The term "light source" may also refer to a mid-power package. A mid-power package may include one or more solid-state dies. The die may be covered by a layer containing a luminescent material. The die size may be equal to or less than 2 mm, for example in the range of 0.2-2 mm. Therefore, in an embodiment, the light source comprises a solid-state light source. Further, in a particular embodiment, the light source comprises a chip-scale packaged LED. In this document, the term "light source" may also refer in particular to a small solid-state light source, for example, having a micro size or a micro size. For example, the light source may include one or more of a micro LED and a micro LED. In particular, in an embodiment, the light source may include a micro LED or a "micro LED" or a "μLED". Here, the term micro size or micro LED particularly refers to a solid-state light source having a size (such as a die size, especially a length and a width) selected from the range of 100 μm–1 mm. Here, the term μ size or micro LED particularly refers to a solid-state light source having a size (such as a die size, especially a length and a width) selected from the range of 100 μm and smaller.

[0112] The light source may have a light escape surface. With reference to conventional light sources such as light bulbs or fluorescent lamps, this may be the outer surface of a glass or quartz housing. For an LED, this may be, for example, the LED die, or, when a resin is applied to the LED die, the outer surface of a resin. In principle, it may also be the terminal end of an optical fiber. The term "escape surface" particularly relates to that part of the light source, where light actually leaves or escapes from the light source. The light source is configured to provide a light beam. The light beam (therefore) escapes from the light exit face of the light source.

[0113] Likewise, the light generating device may comprise a light escape surface, such as an end window. Further, likewise, the light generating system may comprise a light escape surface, such as an end window.

[0114] The term "light source" may refer to a semiconductor light emitting device, such as a light emitting diode (LED), a resonant cavity light emitting diode (RCLED), a vertical cavity laser diode (VCSEL), an edge emitting laser, etc. The term "light source" may also refer to an organic light emitting diode (OLED), such as a passive matrix type (PMOLED) or an active matrix type (AMOLED). In a particular embodiment, the light source comprises a solid-state light source (such as an LED or a laser diode). In an embodiment, the light source comprises an LED (light emitting diode). The term "light source" or "solid-state light source" may also refer to a superluminescent diode (SLED).

[0115] The term LED may also refer to a plurality of LEDs.

[0116] The term "light source" may also relate to a plurality of (substantially identical (or different)) light sources, such as 2-2000 solid-state light sources. In an embodiment, the light source may comprise one or more micro-optical elements (an array of micro-lenses) downstream of a single solid-state light source (such as an LED) or downstream of a plurality of solid-state light sources (i.e., for example, formed by a plurality of LEDs). In an embodiment, the light source may comprise an LED with on-chip optics. In an embodiment, the light source comprises a pixelated single LED (with or without optics) (in an embodiment providing on-chip beam steering).

[0117] In an embodiment, the light source may be configured to provide a primary radiation that is used as follows: such as a blue light source, such as a blue LED; or a green light source, such as a green LED; and a red light source, such as a red LED. Such LEDs that may not include a luminescent material ("phosphor") may be indicated as direct color LEDs.

[0118] However, in other embodiments, the light source may be configured to provide primary radiation, and a portion of the primary radiation is converted into secondary radiation. Secondary radiation may be based on conversion by luminescent material. Therefore, secondary radiation may also be indicated as luminescent material radiation. In an embodiment, the light source may include the luminescent material, such as an LED having a luminescent material layer or a dome including luminescent material. Such an LED may be indicated as a phosphor-converted LED or a PCLED (phosphor-converted LED). In other embodiments, the luminescent material may be configured at a certain distance ("away") from the light source, such as an LED having a luminescent material layer that is not in physical contact with the die of the LED. Therefore, in a particular embodiment, the light source may be a light source that emits at least light of a wavelength selected from the range of 380-470nm during operation. However, other wavelengths are also possible. The light may be partially used by the luminescent material.

[0119] In an embodiment, the light generating means may include a luminescent material. In an embodiment, the light generating means may include a PCLED. In other embodiments, the light generating means may include a direct LED (i.e., without a phosphor). In an embodiment, the light generating means may include a laser device, such as a laser diode. In an embodiment, the light generating means may include a superluminescent diode. Thus, in a specific embodiment, the light source may be selected from the group of a laser diode and a superluminescent diode. In other embodiments, the light source may include an LED.

[0120] The light source may in particular be configured to generate a source light having an optical axis (O), (beam shape) and a spectral power distribution. In embodiments, the source light may comprise one or more frequency bands having a bandwidth as known for lasers.

[0121] The term "light source" may (thus) refer to such a light generating element, such as a solid-state light source, or for example a package of a light generating element (e.g. a solid-state light source), and one or more of the luminescent material including the element and (other) optics (e.g. lenses, collimators). A light converter element ("converter element" or "converter") may comprise an element comprising a luminescent material. For example, a solid-state light source such as a blue LED is a light source. A combination of a solid-state light source (as a light generating element) and a light converter element (e.g. a blue LED and a light converter element optically coupled to the solid-state light source) may also be a light source (but may also be indicated as a light generating device). Thus, a white LED is a light source (but may also be indicated as a (white) light generating device, for example).

[0122] The term "light source" herein may also refer to light sources including solid state light sources, such as LEDs or laser diodes or super luminescent diodes.

[0123] In embodiments, the term "light source" may also (therefore) refer to light sources that are (also) based on light conversion, such as light sources combined with luminescence conversion materials. Thus, the term "light source" may also refer to a combination of an LED and a luminescent material configured to convert at least a portion of the LED radiation, or a combination of a (diode) laser and a luminescent material configured to convert at least a portion of the (diode) laser radiation.

[0124] In an embodiment, the term "light source" may also refer to a combination of a light source (such as an LED) and a filter, which may change the spectral power distribution of the light generated by the light source. In particular, the term "light generating device" may be used to refer to a light source as well as further (optical components) (such as filters and / or beam shaping elements, etc.).

[0125] In an embodiment, the phrase "different light sources" or "a plurality of different light sources" and similar phrases may refer to a plurality of solid-state light sources selected from at least two different groups. Likewise, in an embodiment, the phrase "same light source" or "a plurality of same light sources" and similar phrases may refer to a plurality of solid-state light sources selected from the same group.

[0126] The terms "solid-state light source" or "solid-state material light source" and similar terms may particularly refer to semiconductor light sources, such as light emitting diodes (LEDs), diode lasers or superluminescent diodes.

[0127] Therefore, in embodiments, the central support element solid state light source may be configured to generate central support element solid state light source light. In particular, the central support element device light may include central support element solid state light of one or more central support element solid state light sources.

[0128] Furthermore, in embodiments, the central support element light generating means may be configured to generate a central support element linear beam of central support element means light.

[0129] In certain embodiments, the central support element device light may be colored light.

[0130] The light generating system may be part of or may be applied in, for example, an office lighting system, a home application system, a shop lighting system, a home lighting system, an accent lighting system, a spotlighting system, a cinema lighting system, a fiber optic application system, a projection system, a self-luminous display system, a pixelated display system, a segmented display system, a warning sign system, a medical lighting application system, an indicator sign system, a decorative lighting system, a portable system, an automotive application, a (outdoor) road lighting system, a city lighting system, a greenhouse lighting system, a horticultural lighting, digital projection or an LCD backlight. The light generating system (or illuminator) may, for example, be part of or may be applied in an optical communication system or a disinfection system.

[0131] In yet another aspect, the present invention also provides a lighting device, such as a lamp or illuminator, comprising a light generating system as defined herein. Such a lighting device may be beneficial because the hinged linear structure contained by the lighting device can easily fold the lighting device. The easy folding of the lighting device can lead to more compact storage and transportation of the lighting device. The illuminator may also include a housing, an optical element, a shutter, etc. The lamp or illuminator may also include a housing that encloses the light generating system. The lamp or illuminator may include a light window or a housing opening in the housing, through which the system light can escape from the housing. Therefore, in one aspect, the present invention also provides a light generating device selected from the group consisting of a lamp, an illuminator, a disinfection device, and an optical wireless communication device, including a light generating system as defined herein. The light generating device may include a housing or a carrier, which is configured to accommodate or support one or more elements of the light generating system. For example, in an embodiment, the light generating device may include a housing or a carrier, which is configured to accommodate or support one or more of the light generating device, a pivotable member, and a central support element.

[0132] For example, in an embodiment, the lighting device may include two or more linearly arranged light generating devices. Further, in an embodiment, the lighting device may include two or more pivotable components, and the pivotable components are configured to support the two or more linearly arranged light generating devices. Additionally or alternatively, in an embodiment, the lighting device may include one or more central support elements, such as one central support element, such as two central support elements, and in particular three central support elements.

[0133] Furthermore, in an embodiment, the lighting device can be of a type selected from the group consisting of a standing lighting device, a tabletop lighting device, a hanging lighting device, a handheld lighting device, or a hanging lighting device. Thus, in a particular embodiment, the lighting device can be a chandelier comprising three pivotable components configured to support three light generating devices. The three pivotable components can be further configured to pivot around two central support elements.

[0134] Furthermore, in embodiments, the lighting device may include a linear arrangement of light generating devices that may be at least partially configured in a vertical orientation. In other embodiments, the lighting device may include a linear arrangement of light generating devices that may be at least partially configured in a horizontal orientation.

[0135] In an embodiment, the lighting device may comprise a rectangular shape.

[0136] In alternative embodiments, the lighting device can have a curved shape, for example, a shape selected from the group consisting of: circular, cylindrical, elliptical, beaded, (double) crescent or moon-shaped, heart-shaped, other types of regularly curved shapes, or irregularly curved (or "asymmetric") shapes.

[0137] In yet another aspect, the present invention also provides an arrangement comprising the light generating system. In particular, the light generating system can be configured to provide the first device light and the second device light to two corresponding items selected from the group consisting of a floor, a ceiling, a first wall and a second wall (different from the first wall).

[0138] In an embodiment, the arrangement may include a standing lamp arranged to face (the center of) a wall and configured to illuminate the wall. In other embodiments, the arrangement may include a standing lamp arranged in a corner of a room, i.e., facing two different adjacent walls, and configured to illuminate the two walls. In yet another embodiment, the device may include a chandelier or a hanging lamp arranged to hang from a table or floor. In this case, the lamp may be configured to illuminate one or more of a table, a floor and a ceiling.

[0139] The term "white light" and similar terms herein are known to a person skilled in the art. It may particularly relate to light having a correlated color temperature (CCT) between about 1800K and 20000K (such as between 2000 and 20000K, in particular 2700-20000K) for general lighting, which is particularly in the range of about 2000-7000K (such as in the range of 2700K and 6500K). In an embodiment, for example, for the purpose of backlighting, or for other purposes, the correlated color temperature (CCT) may particularly be in the range of about 7000K and 20000K. Further, in an embodiment, the correlated color temperature (CCT) is particularly within about 15SDCM (standard deviation of color matching) from the BBL (black body locus), particularly within about 10SDCM from the BBL, even more particularly within about 5SDCM from the BBL.

[0140] In certain embodiments, the correlated color temperature (CCT) may be selected from the range of 6000-12000 K, such as from the range of 7000-12000 K, such as at least 8000 K. Furthermore, in embodiments, in combination with a CRI of at least 70, the correlated color temperature (CCT) may be selected from the range of 6000-12000 K, such as from the range of 7000-12000 K.

[0141] In an embodiment, the light source may also provide a source light having a correlated color temperature (CCT) between about 5000 and 20000 K, for example a direct phosphor converted LED (e.g. a blue light emitting diode with a thin phosphor layer to obtain, for example, 10000 K). An advantage of a relatively high color temperature may be that there may be a relatively high blue component in the source light.

[0142] The terms "visible", "visible light" or "visible emission" and similar terms refer to light having one or more wavelengths in the range of about 380-780 nm. Herein, UV may particularly refer to wavelengths selected from the range of 190-380 nm, such as a wavelength in the range of 200-380 nm.

[0143] The terms "light" and "radiation" are used interchangeably herein, unless it is clear from the context that the term "light" refers only to visible light. Thus, the terms "light" and "radiation" may refer to UV radiation, visible light, and IR radiation. In specific embodiments, particularly for lighting applications, the terms "light" and "radiation" refer to (at least) visible light.

[0144] Instead of the term "illumination device" or "illumination system" and similar terms, the term "light generating device" or "light generating system" (and similar terms) may also be applied. A lighting device or a lighting system may be configured to generate device light (or "illumination device light") or system light ("or lighting system light"). As mentioned above, the terms light and radiation may be used interchangeably.

[0145] In specific embodiments, the term UV radiation may refer to near UV radiation (NUV). Therefore, the term "(N)UV" is also used herein to refer to UV in general and to NUV in specific embodiments. In this document, UV (ultraviolet) may particularly refer to wavelengths selected from the range of 190-380 nm, but in specific embodiments, other wavelengths are also possible.

[0146] Here, IR (infrared) may particularly refer to radiation having a wavelength selected from the range of 780-3000 nm, for example 780-2000 nm, for example up to a wavelength of about 1500 nm, such as a wavelength of at least 900 nm, but other wavelengths are also possible in certain embodiments. Thus, the term IR may herein refer to one or more of near infrared (NIR (or IR-A)) and short wavelength infrared (SWIR (or IR-B)), particularly NIR.

[0147] The term "centroid wavelength", also denoted λc, is known in the art and refers to the wavelength value where half of the light energy is at shorter wavelengths and half of the light energy is at longer wavelengths; the value is expressed in nanometers (nm). The wavelength divides the entirety of the spectral power distribution into two equal parts, as represented by the formula λc = Σλ*I(λ) / (ΣI(λ)), where the summation is over the wavelength range of interest, and I(λ) is the spectral energy density (i.e., the product of wavelength and intensity is integrated over the emission band normalized to the integrated intensity). The centroid wavelength can be determined, for example, under operating conditions. BRIEF DESCRIPTION OF THE DRAWINGS
