Description

Technical Field

[0001] The present invention generally relates to a lighting arrangement. More particularly, the present invention relates to a lighting arrangement comprising a rotatable lighting unit. Background Art

[0002] The use of spotlights for lighting purposes is used in a large number of areas, such as hospitals and different types of stage performances, as well as for private use in the home. The property of a spotlight to be able to produce lighting with a well-defined cross section may be desirable in the mentioned areas as well as in additional implementation areas.

[0003] In some spotlight designs, rotation of the spotlight may be possible, allowing the direction of the emitted light beam from the spotlight to be changed. This enables the space in which the spotlight is located to be further illuminated, thus providing a more versatile spotlight. Some designs provide individually rotatable spotlights, while other designs disclose linear rotatable spotlights with several light sources.

[0004] Having light emitting diodes (LEDs) as light sources in spotlights further expands the area of ​​use of spotlights. LEDs have many advantages over traditional light sources, such as being more energy efficient, having a longer life and higher efficiency, and providing design flexibility. Using LEDs in spotlights can also allow different settings of the emitted light to be modified in an accessible manner, such as adjusting the intensity of the light, i.e. dimming.

[0005] The emitted light can also be redirected manually via rotation, such as directing the emitted light beam toward the ceiling to create an indirect lighting experience. This arrangement may require additional space for the spotlight, which may otherwise be disadvantageous because it is generally preferred to have a relatively compact spotlight. A more compact spotlight may be consistent with the desired aesthetic and facilitate handling of the spotlight.

[0006] It is therefore of interest to provide an alternative to prior art spotlights in order to improve the use of such spotlights in the areas of space efficiency and versatility of use.

[0007] DE202016101553U1 discloses a recessed lamp with a rotating LED light source. Summary of the invention

[0008] It is an object of the present invention to provide a lighting arrangement which can combine several lighting functions while being compact and / or space efficient.

[0009] This and other objects are achieved by a lighting arrangement having the features of the independent claim.Preferred embodiments are defined in the dependent claims.

[0010] Thus, according to the present invention, a lighting arrangement is provided, comprising: at least one lighting unit comprising at least one light emitting diode LED as a light source arranged to emit light; and a housing comprising a reflective inner surface. The housing further comprises an opening extending in a plane P, wherein the opening is arranged opposite to the reflective inner surface (a part thereof, such as a part of its curved portion). The at least one lighting unit is rotatably fastened to at least one first rotation axis A of the housing. i , wherein the at least one first rotation axis A i is arranged adjacent to the opening and parallel to the plane P. Furthermore, at least one lighting unit can rotate about at least one first axis A i The at least one lighting unit is rotatable through the opening between a first position and a second position. In the first position, the at least one lighting unit is at least partially surrounded by the cavity of the housing, i.e. is recessed into or accommodated in the cavity of the housing, wherein the at least one lighting unit is arranged to illuminate the reflective inner surface to output light through the opening via reflection at the inner surface. In the second position, the at least one lighting unit is at least partially arranged outside the housing. The lighting unit can rotate within the housing around at least one first rotation axis A. i The rotation is through an inner rotation angle α, which is ≥ 90°, so that when the lighting unit is in the first position, i) the projection of the opening and the lighting unit along the normal of the plane P do not overlap, and ii) the lighting unit emits light into the housing in a direction away from the opening.

[0011] Thus, the present invention is based on the concept or idea of ​​a compact lighting arrangement or system that is capable of providing multi-purpose light by enabling a lighting unit to be rotated at least partially within a housing with a reflective interior. Thus, for a rotation of the lighting unit relative to the housing and its reflective interior, the exit light from the lighting arrangement can be used for different lighting purposes.

[0012] It will be appreciated that the lighting arrangement is relatively compact. The lighting arrangement is relatively compact because it is arranged in an arrangement through the axis of rotation A. i Several lighting functions are provided. Hence, the lighting arrangement requires less space and is easier to handle, for example during transport and / or installation, than prior art arrangements.

[0013] It should also be noted that the lighting arrangement is capable of providing multi-purpose light, for example diffuse light, downlight, and accent light. This may reduce the need for several different lighting arrangements to provide the desired lighting functions. This may be advantageous in different environments where specific light settings may be desired and / or light requirements may vary, such as in hospitals, museums and theaters, etc., as well as in private homes. When the lighting unit is in the first position (i.e., housed inside the inner cavity of the housing), the lighting arrangement is in an indirect mode and provides indirect lighting. In the indirect mode, the interior of the housing acts as a mixing chamber so that the opening has a uniform light intensity with substantially no distortion caused by the lighting unit. Alternatively or additionally, in the first position, the outline of the lighting unit is not visible through the opening in a viewing direction along the normal.

[0014] A further advantage of the invention is that it provides a safer lighting arrangement with respect to at least some external forces, e.g. during transport and / or installation of the lighting arrangement. Lighting arrangements may often need to be handled with care, as they may be fragile and / or comprise sensitive components, such as light sources and electrical wiring etc. Since the lighting unit comprising the light source can be rotated such that the lighting unit is at least partially surrounded by the housing, the light source of the lighting arrangement may be protected.

The lighting arrangement 100 comprises a housing 130, which comprises a reflective inner surface 140 and an opening 150. Thus, the reflective inner surface 140 may occupy only part or all of the interior of the housing 130. The reflective inner surface 140 may obtain its reflective properties by including, for example, a reflective coating or sheet. In addition, the type of reflection from the reflective inner surface 140 may be, for example, specular reflection and / or diffuse reflection. The type of reflection may be obtained by the properties of the reflective inner surface 140 (for example, portions of its surface are regular and / or irregular). In addition, the opening 150 extends in a plane P, wherein the opening 150 is arranged opposite to the reflective inner surface 140. Figure 1 The housing 130 is disclosed as being in the shape of a quarter cylinder having an elliptical cross-section. However, it should be noted that the housing 130 may take alternative shapes, such as a half cylinder, a sphere, a triangular prism, and the like.

[0039] The lighting arrangement 100 also includes at least one lighting unit 110, which further includes at least one light source 120. Therefore, the lighting arrangement 100 may include a plurality of lighting units 110. Similarly, the lighting unit 110 may include a plurality of light sources 120. In the case where there are a plurality of light sources 120, the light sources 120 may be arranged directly adjacent to each other, or slightly spaced apart. In addition, the plurality of light sources 120 may be arranged in a linear array. For example, the light source 120 may preferably be or include a light emitting diode LED, but may alternatively be or include an incandescent light source, a fluorescent light source, etc. In the case where there are a plurality of lighting units 110, the lighting units 110 may be arranged in a linear array. The lighting arrangement 100 may also include a single lighting unit 110 and a single light source 120. In this case, the single lighting unit 110 and the single light source 120 may constitute a linear (light) array.

[0040] The lighting unit 110 is rotatably fastened to the first rotation axis A of the housing 130. i . First rotation axis A i The lighting unit 110 is arranged adjacent to the opening 150 and parallel to the plane P. The lighting unit 110 can rotate around the first rotation axis A between the first position and the second position through the opening 150 i Therefore, the lighting unit 110 can rotate around the first rotation axis A iThe lighting unit 110 is rotated between various positions positioned between the first position and the second position. In the first position, the lighting unit 110 is at least partially surrounded by the cavity 135 of the housing 130, or is at least partially recessed or accommodated in the cavity 135 of the housing 130, wherein the lighting unit 110 is arranged to illuminate the reflective inner surface 140 to output light through the opening 150. The reflective inner surface 140 can be fully illuminated or only partially illuminated. In the second position, the lighting unit 110 is at least partially arranged outside the housing 130. Therefore, the lighting unit 110 in the second position can illuminate the reflective inner surface 140 to a certain extent or not illuminate the reflective inner surface 140 at all.

At least one lighting unit 110 comprises at least one optical unit 160, in the figure a reflective element (but it may alternatively or additionally comprise a refractive body, such as a lens element), which is configured to guide light. The optical unit 160 may guide light via, for example, optical guidance of light and collimation of light.

[0042] The lighting arrangement 100 further comprises an aperture, wherein the optical unit 160 is arranged perpendicular to the at least one first rotation axis A. i Directly (and therefore not reflected by the reflective element) a portion of the light is directed through the aperture. In addition, the optical unit 160 is rotatably fastened to at least one first rotation axis A at the periphery of the aperture. i . Figure 2 A plurality of first rotation axes A1 and A2 are disclosed. Thus, the optical unit 160 is rotatably fastened to the first rotation axes A1 and A2 along the light emitting window of the lighting unit 110, respectively.

[0043] The lighting arrangement 100 further comprises a control unit 170, which is configured to individually control the light sources 120 via at least one setting of the light sources 120. The control unit 170 may be connected to the light arrangement 100 by wire or wirelessly. Because the control unit 170 may independently control the light sources 120, different light sources 120 may have different settings, for example regarding brightness and / or color. The control of the light sources 120 via the settings is based on input from at least one of a sensor 175 and / or a user. In the case where the control is based on input from the sensor 175, the sensor 175 may be configured, for example, to detect movement. For example, if any movement (of a person) is detected, the sensor 175 may generate a sensor signal and send the generated signal to the control unit 170, and the control unit 170 may control the light sources 120 to, for example, increase brightness and / or color. Furthermore, the control of the light sources 120 is based on the rotation of the lighting unit 110 around at least one first axis of rotation A. i Rotation between a first position and a second position. For example, the light source 120 may have different settings for whether the lighting unit 110 is completely surrounded by (or contained in) the cavity 135 of the housing 130 or is arranged completely outside the housing 130. The setting may be at least one of the color of the light, the color temperature, the intensity, the beam direction, and the beam distribution. For example, the color may be adjusted to, for example, present a cool white light output to mimic the sky, a pleasing ambient color defined by a potential user, or the color may be based on a color derived from a light scene active in the space in which the lighting arrangement 100 is located.

[0044] It should be noted that the setting determinants may be performed manually and / or automatically, i.e. the setting is based on the rotation of the lighting unit 110 and / or input from the sensor 175 and / or the user. For example, the sensor 175 may automatically detect any movement within the space where the lighting arrangement 100 is located in order to be able to change, for example, the photometric value, whereas the lighting unit 110 may be rotated manually in order to be able to change, for example, the color of the emitted light.
