Description

background

[0001] Portable work lights are used to provide illumination in environments where work needs to be carried out. The term "portable" here means that something is movable and can be easily lifted and moved from one place to another by a user with one hand. Portable work lights may include a housing containing a light source and often have an adjustable stand that allows the light to be directed where needed. The light source may be an incandescent bulb, a light-emitting diode (LED), or an LED panel, often providing a high-intensity, point-source or near-point-source light source. This type of light often casts shadows when directed at a complex and densely packed target, such as when used to illuminate a vehicle's engine compartment or a drainpipe under a sink.In some cases, the bright point light can also distract the user because the light shines directly into their eyes or is reflected from nearby surfaces. For these reasons alone, it is desirable to provide a work light that is portable, offers high light output, and is a distributed light source. Furthermore, other portable work lights are known. For example, GB 2,558,945 A describes a safety device for illuminating an articulated vehicle. GB 2,511,436 A describes a lighting device that can form a loop that can be worn as a belt or sash, the loop being arranged to generate and emit light. CN 2,092,457,771 U also describes an anti-fall magic light bar. US 6,925,967 B 1 describes an illuminated, retractable pet leash. Brief description

[0002] The work light is portable and cordless. It comprises an elongated, flexible light assembly that can be stored in a robust housing, for example, by winding the assembly onto a spool provided within the housing. The housing is generally disc-shaped and at least partially translucent. The flexible light assembly is a structurally reinforced light strip capable of emitting light along its entire length.

[0003] The work light can be configured in several ways, allowing it to be adapted to different work environments with varying lighting requirements. For example, the flexible light assembly can be fully retracted into the housing for storage and easier portability. In this fully retracted configuration, the flexible light assembly can be powered, emitting light from the translucent parts of the housing. In this configuration, the work light provides diffused light, similar to a conventional work light, for general illumination. In other configurations, the flexible light assembly can be extended relative to the housing.In these configurations, both the housing and the flexible luminaire assembly emit light, allowing the housing and the flexible luminaire assembly to work together to provide an elongated, distributed light source.

[0004] In some embodiments, the distal end of the flexible light assembly can terminate in a spotlight. The spotlight emits a relatively intense and focused light compared to the flexible light assembly. Because the spotlight is located at one end of the flexible light assembly, it can be easily aimed as needed when the work light is extended and inserted into confined spaces to provide workplace illumination. When the work light is in the retracted configuration, the spotlight can be accommodated in a recess of the housing, allowing the work light to maintain a clean appearance and / or low profile. In the retracted configuration, the spotlight can be aimed as needed by appropriately positioning the housing.

[0005] In other embodiments, the distal end of the flexible light assembly can terminate in a hook, which can be used to suspend the work light from suitable structures. The work light can be supported by the hook, or alternatively, a flat surface of the housing can rest on a support surface. The housing can also include a foot, which is stored in a recess of the housing. The foot can be unfolded to serve as a stand, allowing the housing to be aligned on one of its edge surfaces. In the unfolded configuration, the foot can alternatively serve as a hanger from which the housing can be suspended.

[0006] The work light provides a wide, diffused light that minimizes shadows in areas with poor visibility. The flexible light assembly itself delivers a distributed light that is less intense per unit area compared to a typical work light, thus reducing glare and reflections.

[0007] In some embodiments, the flexible lighting assembly includes a light strip in which light sources, such as LEDs, and other supporting electronic components are distributed along an area of ​​a substrate. The electronic components may include, for example, resistors. The substrate is in the form of a very thin, flexible, conductive strip or film. The substrate may be very thin, for example, about 0.1 mm to 0.5 mm thick, and made of metal such as copper or another conductive material. If unsupported, the substrates may be fragile, particularly with respect to tensile strength, as well as resistance to repetitive stress, lateral bending, and torsional stress. The substrate may tear or wrinkle, or the non-flexible components, including the light sources and resistors, may be damaged or detach.The light strips also lack tensile strength in the longitudinal direction. For this reason, the substrate in the flexible lighting assembly is reinforced. For example, the substrate is provided with a reinforcing layer on the side opposite the light emitters. This reinforcing layer can be a flexible strip of metal or plastic that serves as a base for the substrate. The reinforcing layer is a strengthening element that can absorb the tensile load while simultaneously resisting off-axis bending and twisting.

[0008] The substrate, the reinforcement layer, and the light emitters are enclosed in a flexible, waterproof sheath that also serves as a light guide. The sheath can be made of silicone, but also of other flexible and transparent materials. The sheath itself can be further reinforced. In some embodiments, for example, the sheath may contain embedded fibers or cords that provide additional strength.

[0009] In some embodiments, the housing for the work light is an elongated, flexible exoskeleton. In this embodiment, the flexible light assembly, including the substrate, the reinforcing layer, and the light emitters enclosed in the flexible, waterproof casing, is arranged in a flexible, elongated housing that acts as a superstructure and surrounds the flexible light assembly substantially along its entire length. The exoskeleton can take two forms: The first form is a single reinforcing body attached to the outside of the flexible light assembly, offering similar advantages to an internal rigid icing element. The second form is a segmented or hinged assembly that bends around an axis.The segments connected in series by hinges would allow bending in one direction, but resist movements in off-axis directions, twisting or pulling directions.

[0010] According to some definitions, a lighting device comprises a housing and a light-emitting first body located within the housing. The housing includes a stator with a side wall and an end wall that closes one end of the side wall. The stator is opaque. The housing includes a rotor that closes the other end of the side wall. The second end is opposite the first end. The rotor, the side wall, and the end wall together define a housing interior. The rotor includes a cylindrical coil that projects into the housing interior, and at least part of the rotor is transparent. The light-emitting first body is located within the housing and serves as the light source. The first body comprises a substrate with a length, a width, a thickness, a first end, and a second end opposite the first end.A length dimension of the substrate is much larger than a width dimension of the substrate. The width dimension is much larger than a thickness dimension of the substrate. The second end is separated from the first end by the length dimension. The length dimension is larger than a maximum dimension of the housing interior. The first body also includes light emitters arranged on a first surface of the substrate such that they are spaced apart in a direction parallel to the length dimension. The first end of the first body is connected to the coil. Furthermore, the light source is configurable between a retracted configuration, in which the first body is located inside the housing interior and light emitted by the first body is transmitted through the rotor, and an extended configuration.In the extended configuration, the first end of the first body is located inside the housing, while the second end and a central portion of the first body are located outside the housing. Part of the light emitted by the first body is transmitted through the rotor, and another part originates outside the housing. The second end of the first body terminates in a second light-emitting body. Furthermore, the housing includes a recess configured to accommodate the second body, and when the light source is in the retracted configuration, the second body is positioned within this recess.

[0011] In some embodiments, the rotor is rotatable relative to the stator about an axis of rotation that runs parallel to the side wall and concentric to the coil, and a rotation of the rotor relative to the stator causes the first body to wind onto or off a surface of the coil.

[0012] In some embodiments, the stator includes an opening, the first body extends through the opening, and the second end of the first body is secured so that it is located outside the housing.

[0013] In some embodiments, the first end of the first body is connected to the coil via a swivel joint.

[0014] In some embodiments, the first body retracts into the housing when the coil is rotated so that the first body winds onto the coil.

[0015] According to the invention, the second end of the first body terminates in a light-emitting second body.

[0016] In some embodiments, the second body is a headlight.

[0017] In some embodiments, the second body is shaped and dimensioned in such a way as to prevent the second end of the first body from being drawn in through the opening.

[0018] According to the invention, the housing includes a recess configured to accommodate the second body, and when the light source is in the retracted configuration, the second body is arranged in the recess.

[0019] In some embodiments, the first body is enclosed in a waterproof casing that includes structural reinforcement configured to improve tensile strength.

[0020] In some embodiments, the first body includes a hook that protrudes from the second end.

[0021] In some embodiments, the lighting device includes a power source, wherein the power source is supported by the coil.

[0022] In some embodiments, the housing includes a foot. The foot comprises a proximal end rotatably connected to the housing and a distal end opposite the proximal end. The foot is movable between a stowed configuration, in which the distal end rests against the housing, and an angled configuration, in which the distal end is spaced away from the housing.

[0023] In some embodiments, an outward-facing surface of the rotor includes a pair of finger grip openings shaped and sized to accommodate a user's fingertips.

[0024] According to some definitions, a lighting device comprises a housing and a light-emitting first body located within the housing. The housing includes a rotor, which is at least partially translucent, and a stator, which together with the rotor defines an interior space. The stator has an opening that allows a connection between the interior space and an exterior of the housing. The light-emitting first body is located within the housing and serves as the light source. The first body includes a substrate. The substrate has a length, a width, a thickness, a first end, and a second end opposite the first end. A length dimension of the substrate is much greater than a width dimension of the substrate, and the width dimension is much greater than a thickness dimension of the substrate. The second end is separated from the first end by the length dimension.The length dimension is greater than a maximum dimension of the interior. The first body also incorporates light emitters arranged on a first surface of the substrate such that they are spaced apart in a direction parallel to the length dimension. The first body extends through the opening. The first end of the first body is secured so that it is located within the interior. The second end of the first body is secured so that it is located outside the housing. The light source is configurable between a retracted and an extended configuration. In the retracted configuration, the first end and a middle portion of the first body are located within the interior, and light emitted by the first body is transmitted through the rotor.In the extended configuration, the first end of the first body is located inside the housing, while the second end and the middle portion of the first body are outside. Furthermore, some of the light emitted by the first body is transmitted through the rotor, and another portion originates outside the housing. In this configuration, the second end of the first body terminates in a second light-emitting body. The housing also includes a recess configured to accommodate the second body, and when the light source is in the retracted configuration, the second body is positioned within this recess.

[0025] In the Fig. Figures 1 to 9 depict a portable, wireless lighting device 1, 201 comprising a housing 2 and a flexible lighting assembly 100. The flexible lighting assembly 100 is an elongated, flexible strip resembling a tape or ribbon and contains light-emitting elements, such as LEDs, distributed along its length, thus providing the light source for the lighting device 1, 201. The housing 2 includes translucent parts. Furthermore, the flexible lighting assembly 100 can be stored or operated in a retracted configuration, in which it is wound up within the housing 2, or alternatively, in an extended configuration, in which it protrudes from the housing 2.Since the lighting device 1,201 is capable of assuming multiple configurations that provide general lighting, task lighting, or both, it is ideally suited to serve as a work light capable of meeting the lighting requirements of various work environments. Details regarding the configurability of the lighting device 1,201 are described below. Furthermore, the flexible luminaire assembly 100 incorporates structurally reinforcing features that provide a reliable and durable light strip, even when used in diverse work environments. Details of the flexible luminaire assembly 100, including its structurally reinforcing features, are described below.

[0026] The housing 2 of the lighting device 1, 201 is rigid, generally disc-shaped, and has a size and weight that allow the housing 2 to be easily lifted and moved from one place to another by a user with a single hand. The housing 2 includes a stator 10 and a rotor 50, which is rotatably mounted on the stator 10.

[0027] According to Fig. 12 and Fig. The stator 10 includes a circular side wall 11 that surrounds a center line 14 of the stator 10. The stator 10 includes a stator end wall 17 that closes a first end 12 of the side wall 11. The side wall 11 and the stator end wall 17 give the stator 10 the shape of a flat shell. In addition to the side wall 11 and the end wall 17, the stator 10 also includes a foot 26 that is movable between a folded and an unfolded configuration, the foot 26 serving, in the unfolded configuration, to hold the housing 2 in an upright orientation.

[0028] The stator 10 has a low profile in that the axial dimension a1 of the side wall 11 is small in relation to the diameter d1 of the side wall 11. In the illustrated embodiment, the axial dimension a1 of the side wall is, for example, about one-tenth of the side wall diameter d1.

[0029] The side wall 11 includes a side wall opening 16, which allows passage between an interior space 3 of the housing 2 and the environment of the lighting device 1, 201. The side wall opening 16 is sufficiently large to allow the flexible lighting assembly 100 to pass through it.

[0030] The stator end wall 17 includes a central opening 18 centered on the stator centerline 14. The central opening 18 is large relative to the size of the stator end wall 17. In the illustrated embodiment, for example, the central opening 18 has a diameter d2 that is approximately half the side wall diameter d1, where the side wall diameter d1 corresponds to a diameter of the stator end wall 17.

[0031] An outwardly facing surface 17(1) of the end wall 17 can contain a recess 24 surrounding the central opening 18. The recess 24 has a profile corresponding to a circumferential shape of the foot 26, which is pivotally attached to the outwardly facing stator surface 17(1). In the illustrated embodiment, where the foot 26 has the shape of a flattened ring, the profiles of the foot 26 and the recess 24 are generally circular. In particular, the recess 24 includes a circular part 24(1) that receives the foot 26 and a straight part 24(2) that receives a hinge block 22, which serves to receive a pin (not shown) connecting a proximal end 32 of the foot 26 to the end wall 17. The recess 24 is sufficiently deep to fully or substantially fully accommodate the foot 26 when the foot 26 is in a folded configuration.When the foot 26 is in an extended configuration, a distal end 34 of the foot 26 is spaced away from the stator end wall 17. When the housing 2 rests on a horizontal surface over the folded foot 26 (as in . Fig. (as shown in Figure 1), the lighting device 1, 201 can be operated in a horizontal orientation. If the housing stands on a horizontal surface via the extended foot 26 (as shown in Figure 1), the lighting device 1, 201 can be operated in a horizontal orientation. Fig. (as shown in Figure 2), the lighting device 1, 201 can be operated in a vertical or upright orientation.

[0032] An outwardly facing surface 11(1) of the side wall 11 may include projecting flat, linear ribs 15. The ribs 15 are spaced apart along a circumference of the side wall 11 and extend in a direction parallel to the stator centerline 14. In some embodiments, the ribs 15 give the stator 10 a roughened surface texture, which makes it easier for a user to grip the stator manually.

[0033] The stator 10 is opaque. In this context, "opaque" means that no light, or substantially no light, is transmitted. "Substantially no light transmission" means that a maximum light transmission of zero to three percent of the emitted light is possible. Although the stator 10 in the illustrated embodiment is made of a hard, durable plastic suitable for injection molding, any suitable material can be used to manufacture the stator 10.

[0034] As in Fig. As shown in Figures 6 to 11 and 14 to 16, the rotor 50 includes a rotor end wall 51 and a coil 58 projecting from an inwardly facing surface 51(1) of the rotor end wall 51. The coil 58 is a hollow cylinder with an outer diameter d3, which allows the coil 58 to project in a sliding fit through the central opening 18 of the stator 10. The coil 58 is centered on the stator center line 14, and a rotation of the rotor 50 relative to the stator 10 results in a corresponding rotation of the coil 58 about an axis of rotation 54 that coincides with the stator center line 14. The coil 58 has an axial dimension a2 (e.g., a dimension in a direction parallel to the axis of rotation 54) that is equal to or slightly larger than an axial dimension of the stator 10.

[0035] The hollow interior of the coil 58 is divided into three separate compartments by a first inner wall 66 and a second inner wall 68. The first and second inner walls 66, 68 do not intersect each other. Both the first and second inner walls 66, 68 are slightly curved, and a central space 67 is located between them. During operation, the central space 67 between the first and second inner walls 66, 68 houses a power supply for the lighting device 1, 201 in the form of a battery 90, as will be explained in more detail below.

[0036] The rotor end wall 51 includes a pair of finger openings 55, 56 located within the area enclosed by an inner surface 58(1) of the coil 58. A first finger opening 55 of the pair of finger openings 55, 56 is defined between the first inner wall 66 and a first section 58(1a) of the coil's inner surface 58(1). Similarly, a second finger opening 56 of the pair of finger openings 56 is defined between the second inner wall 68 and a second section 58(1b) of the coil's inner surface 58(1). The first and second finger openings 55, 56 are elongated in a direction perpendicular to the axis of rotation 54 and can be dimensioned to accommodate a user's fingertip. The first and second finger openings 55, 56 can be grasped by the fingers of a user when he rotates the rotor 50 relative to the stator 10.

[0037] The coil 58 includes an axial slot 60 at a point that intersects the central space 67. At a point diametrically opposite the slot 60, an outer surface 58(2) of the coil 58 has a flattened portion 58(3). The rotor includes a stop 62 that projects inwards from the inwardly facing surface 51(1) of the rotor end wall. The stop 62 runs parallel to the flattened portion 58(3) and is located a short distance from it. The facing surfaces of the flattened portion 58(3) and the stop 62 contain mirror-image recesses 58(4), 62(1) which are shaped and dimensioned to receive and retain a first end 101 of the flexible lighting assembly 100. Through this configuration, the flattening 58(3) and the stop 62 work together to connect the first end 101 of the flexible lighting assembly 100 to the coil.In the illustrated embodiment, the first end 101 of the flexible lighting assembly 100 is slightly enlarged compared to the rest of the flexible lighting assembly 100 to facilitate this connection.

[0038] A rotation of the rotor 50 relative to the stator 10 in one direction leads to the flexible lighting assembly 100 being wound onto the coil 58 and to the flexible lighting assembly 100 being drawn into the housing 2. A rotation of the rotor 50 relative to the stator 10 in the opposite direction leads to the flexible lighting assembly 100 being unwound from the coil 58 and to the flexible lighting assembly 100 being advanced out of the housing 2.

[0039] The rotor 50 is made of a translucent material. In some embodiments, the material used to form the rotor 50 is translucent. The term "translucent" here refers to a transmission and scattering of light such that objects located behind the material are not clearly visible. In other embodiments, the material used to form the rotor 50 is transparent. The term "transparent" here refers to the property of transmitting light without significant scattering, so that objects located behind the material are clearly visible. Although the rotor 50 in the illustrated embodiment is made of a hard, durable plastic suitable for injection molding, any suitable material with appropriate light transmission properties can be used to form the rotor 50.

[0040] Since the rotor 50 is translucent and at least part of the flexible lighting assembly 100 is always located in the housing interior 3 defined between the stator 10 and the rotor 50, the housing 2 serves as a light source when the flexible lighting assembly is supplied with power.

[0041] According to Fig. 10 and Fig. In the illustrated embodiment, the housing 2 includes an overmolded element 80 that covers a circumferential section of the outwardly facing surface 51(2) of the rotor end wall 51 as well as a circumferential edge 51(3) of the rotor end wall 51. The overmolded element 80 can be attached to the rotor 50 by a snap-fit ​​connection or another conventional joining method. In some embodiments, the overmolded element 80 can be used to protect the rotor 50 from impacts. In other embodiments, the overmolded element 80 can have a contrasting color and / or translucency compared to the rotor 50 and can be used to give the housing 2 a more attractive appearance. For this purpose, an inner circumferential edge 80(1) of the overmolded element 80 can have an irregular and / or curved shape.

[0042] As in Fig. As shown in Figures 6 to 9, the lighting device 1, 201 includes the battery 90, which supplies power to the flexible lighting assembly 100. The battery 90 is housed in a battery holder 92, which in turn is located in the central space 67 defined in the coil 58 between the first and second inner walls 66, 68. The battery holder 92 may also include a control switch (not shown), a circuit board (not shown), and / or power control electronics (not shown). Thus, the battery 90 and the associated electronics are housed in the central space 67 of the coil 58, which is formed integrally with the rotor 50. Consequently, the battery 90 and the associated electronics rotate with the coil 58, so that no electricity or signals need to be transmitted between two rotating bodies. This configuration also allows for a more compact housing 2.

[0043] The control switch can be a simple on / off switch or, alternatively, a multi-mode selector switch that allows a choice between an "off" mode and various "on" modes. The various on modes can allow a choice between one or more constant on modes and various intermittent on modes (fast flashing, slow flashing, etc.) and / or a choice between different power levels (high intensity, medium intensity, low intensity). The circuit board can be electrically connected to the power source via the control switch and can carry the power control electronics and / or an "amplifier board" 94, which regulates a voltage supplied to the flexible lighting assembly.

[0044] During operation, the battery holder 92 is held in the central space 67 by a battery cover 98. In some embodiments, the battery cover 98 is connected to the open end 58(5) of the coil 58 by fasteners such as screws (not shown). The battery cover 98 may include a switch opening 99 through which the control switch protrudes from the housing 2 and is accessible to a user.

[0045] As in Fig. As shown in Figures 17 to 21, the flexible luminaire assembly 100 provides the light source for the lighting device 1, 201. The flexible luminaire assembly 100 comprises a first assembly end 101 and a second assembly end 102 opposite the first assembly end 101. The flexible luminaire assembly 100 has an assembly centerline 103 that extends between the first and second assembly ends 101, 102.

[0046] The flexible lighting assembly 100 is elongated and has the shape of a strip or tape. The flexible lighting assembly 100 has, for example, a length dimension measured in a direction parallel to the assembly centerline 103. In the illustrated embodiment, the length dimension is at least ten times a width or thickness dimension of the flexible lighting assembly. Furthermore, in some embodiments, the width-to-thickness ratio is 1:1. In other embodiments, the width-to-thickness ratio is 2:1. In further embodiments, the width-to-thickness ratio is 5:1 or greater. In a non-limiting example, the flexible lighting assembly can have a length of 0.30 m or more, a width of 15 mm, and a thickness of 5 mm.

[0047] The flexible luminaire assembly 100 comprises a substrate 110, light-emitting elements 130, and additional electrical components 132, which are mounted on the substrate 110. The flexible luminaire assembly 100 includes a casing 120 that encloses the substrate 110, the light-emitting elements 130, and the additional electrical components 132. Furthermore, the flexible luminaire assembly 100 includes structures 107 and 140 that provide structural reinforcement, as will be explained in more detail below.

[0048] The substrate 110 can be a very thin, electrically conductive strip or film ( Fig. 19) In some embodiments, the substrate 110 is, for example, a copper strip. In other embodiments, the substrate 110 may be a flexible printed circuit board containing embedded electrical conductors that connect the light-emitting elements 130 and the additional electrical components 132 to the battery and, in some embodiments, to a control circuit.

[0049] The substrate 110 comprises a first end 111 and a second end 112 opposite the first end 111. The substrate 110 has a rectangular cross-section and thus four sides. The four sides of the substrate 110 comprise a first side 113 and a second side 114, which is opposite the first side 113 and spaced apart from the first side 113 in a thickness direction of the substrate 110. The four sides of the substrate 110 also comprise a third side 115 and a fourth side 116, which is opposite the third side 115 and spaced apart from the third side 115 in a width direction of the substrate 110. The light emitters 130 and additional electronic devices such as resistors, etc., are arranged on the first side 113 of the substrate 110, as explained in more detail below.

[0050] The substrate 110 has proportions that are generally similar to those of the flexible lighting assembly 100. In particular, the substrate 110 has a length dimension, measured between the first substrate end 111 and the second substrate end 112, that is much greater than its width or thickness. In the illustrated embodiment, the substrate can have a length of 0.30 m or more, a width of 10 mm, and a thickness of 0.1 mm to 0.5 mm. In the illustrated embodiment, the first substrate end 111 coincides with or is in close proximity to the first end 101 of the flexible lighting assembly, and the second substrate end 112 coincides with or is in close proximity to the second end 102 of the flexible lighting assembly.

[0051] According to Fig. 20 and Fig. In the illustrated embodiment, the substrate 110 is not only electrically conductive but also very flexible. However, due to its thinness and, in some cases, its material properties, the substrate 110 is not tensile strong and can tear when twisted. To increase its robustness, a reinforcing layer 140 is attached to the second side 114 of the substrate 110, for example, with an adhesive. The reinforcing layer 140 can have a length and width corresponding to the length and width of the substrate 110. The reinforcing layer 140 is made of a material with higher strength than that of the substrate 110. In the illustrated embodiment, the reinforcing layer 140 is made of a very thin metal strip. In a non-limiting example, the reinforcing layer 140 can be a steel strip with a thickness of 0.1 mm. In other embodiments, the reinforcing layer 140 can be made of plastic or a fabric.By providing the substrate 110 with a reinforcement layer 140 as a base, the reinforcement layer 140 can absorb loads in the tensile direction and at the same time resist off-axis bending and twisting.

[0052] The light emitters 130 are attached to the first substrate side 113 and electrically connected to the battery 90 via the substrate 110. In the illustrated embodiment, the light emitters 130 are LEDs, but they are not limited to this type of light emitter.

[0053] Each of the light sources 130 can use one or more LEDs. In particular, the light sources 130 can be provided as surface-mounted LEDs, separate LED packages, or as conventional LEDs housed in an epoxy lens / encapsulation. In some embodiments, the light source 130 can produce white light by using three individual LEDs emitting three primary colors (i.e., red, green, and blue) or by coating the LEDs with a phosphor material. In other embodiments, one or more of the LEDs can be RGB LEDs to produce light in several different colors by selectively illuminating the LEDs to mix the colors.

[0054] The casing 120 provides a flexible, waterproof enclosure for the substrate 110, the light emitters 130, and the reinforcement layer 140. The casing 120 includes a first casing end 121, which coincides with the first end of the assembly 101, and a second casing end 122, which coincides with the second end of the assembly 102.

[0055] The casing 120 has a rectangular cross-section and thus four sides. The four sides of the casing 120 include a first side 123 and a second side 124, which is opposite the first side 123 and spaced apart from the first side 123 in a thickness direction of the casing 120. The four sides of the casing 120 also include a third side 125 and a fourth side 126, which is opposite the third side 125 and spaced apart from the third side 125 in a width direction of the casing 120.

[0056] Furthermore, the casing 120 includes an inner cavity 128 that extends in a direction parallel to the assembly centerline 103. In some embodiments, the inner cavity 128 extends between the first and second ends of the casing 121, 122. The substrate 110, the reinforcing layer 140, and the light emitters 130 are arranged in the inner cavity 128 such that the first substrate side 113 faces the first casing side 123, the second substrate side 114 faces the second casing side 124, and the reinforcing layer 140 is arranged between the substrate 110 and the second casing side 124.

[0057] At least parts of the sheathing 120 are translucent. In some embodiments, the sheathing 120 can, for example, be made of a translucent and flexible material such as silicone, and all parts of the sheathing 120 are translucent. In other embodiments, one pair of opposite sides of the sheathing 120, for example the third and fourth sides 125, 126 of the sheathing 120, is translucent, while the other pair of opposite sides of the sheathing 120, for example the first and second sides 123, 124, is opaque. Fig. 3) In another embodiment, the first side 123 of the sheath 120 is translucent, while the second, third, and fourth sides 124, 125, 126 are opaque. In further embodiments, the second side 124 of the sheath 120 is opaque, while the first, third, and fourth sides are translucent. The translucent parts of the sheath 120 can be transparent or translucent, depending on the application. In some embodiments, the opaque parts of the sheath 120 can be made opaque by coating or overmolding them with an opaque material. In other embodiments, the opaque parts of the sheath 120 can be made opaque by selecting the appropriate material.This means that the translucent parts of the casing 120 can be made of a translucent material, while the opaque parts of the casing 120 can be made of an opaque material.

[0058] The flexible lighting assembly 100 is flexible. For example, the flexible lighting assembly 100 is flexible enough that the first assembly end 101 can bend relative to the second assembly end 102 about an axis perpendicular to the assembly centerline 103 and parallel to the width of the flexible lighting assembly 100, such that the assembly centerline 103 can assume a radius of curvature in a range of 1.3 centimeters to 10.2 centimeters. In the illustrated embodiment, the flexible lighting assembly 100 is flexible enough that the first assembly end 101 can bend relative to the second assembly end 102 about the axis 104 perpendicular to the assembly centerline 103, such that the assembly centerline 103 can assume a radius of curvature of 5.1 centimeters.

[0059] The sheath 120 protects the substrate 110 and the light emitters 130 from the environment and can provide structural reinforcement of the substrate 110. In some embodiments, the sheath 120 can include embedded reinforcing fibers or cords 129 to provide enhanced structural reinforcement of the substrate 110. The reinforcing fibers or cords 129 can be randomly distributed and / or oriented, or arranged or ordered within the sheath material to optimize desired strength properties.

[0060] In the illustrated embodiment, the first sheath end 121 can be closed by a cap 127, which is shaped and dimensioned to fit into the recesses 58(4) and 62(1) provided in the flattened area 58(3) of the coil 58 and in the stop 62 facing the flattened area 58(3). The cap 127 can include one or more openings (not shown) for electrical conductors (not shown) extending between the battery 90 and the substrate 110.

[0061] With reference to Fig. 22 and Fig. In other embodiments, the first sheath end 121 can terminate in a pivoting bracket 138, which allows the flexible lighting assembly 100 to pivot about an axis parallel to the assembly centerline 103 relative to its connection point on the coil 58. This feature advantageously allows the flexible lighting assembly 100 to be pivoted between a first, in Fig. 22 shown orientation and a second one, in Fig. to rotate to the orientation shown in 23. In the Fig. 22 and Fig. Figure 23 shows the lighting device 1, 201 in a schematic cross-sectional view. Fig. 22 A lateral direction of the flexible lighting assembly runs parallel to an axial direction of the coil 58, which enables the flexible lighting assembly to be wound and unwound around the coil 58. In Fig. 23 is the flexible lighting assembly 100 compared to the one in Fig. The 22 shown are rotated 90 degrees. The swivel function allows light to be directed in a desired direction.

[0062] With renewed reference to Fig. 1 to 3 The second end of the flexible lighting assembly 102 can terminate in a secondary light source, such as a spotlight 180. The spotlight 180 can be electrically connected to the battery 90 via the substrate 110. The spotlight 180 includes light sources, which can be LEDs or, alternatively, another type of light source, such as, but not limited to, one or more incandescent bulbs. The spotlight 180 can be mechanically connected to the second sheath end 122 in such a way that it closes the second sheath end 122. Furthermore, the spotlight 180 can be mechanically connected to the second sheath end 122 in such a way that the light emitted by the spotlight 180 is generally directed in a direction parallel to the center line 103 of the flexible lighting assembly. This can correspond to the direction of light emission from the primary light source (e.g.,of the flexible lighting assembly 100), which generally runs perpendicular to the center line 103 of the flexible lighting assembly. In some embodiments, the quality, color, and / or intensity of the light emitted by the headlight 180 differs from that of the flexible lighting assembly 100. In some embodiments, the headlight 180 can be configured to direct a narrow, intense beam of light onto a small area.

[0063] In the illustrated embodiment, the headlight 180 is larger than the second casing end 122 and the side wall opening 16. This configuration prevents the headlight 180 from being retracted into the housing 2 and the flexible lighting assembly 100 from being retracted too far. In some embodiments, the housing side wall 11 may include a recess 11(2) near the side wall opening 16, which is dimensioned and shaped to accommodate the headlight 180. Thus, when the flexible lighting assembly 100 is fully retracted, the headlight 180 is located in the side wall recess 11(2), protecting the headlight 180 during storage and transport and maintaining a uniform appearance on the outer surface of the housing 2.

[0064] With renewed reference to Fig. 4 and Fig. 5, Fig. 8 and Fig. In an alternative embodiment of the lighting device 201, as described in figures 9, 17, and 18, the second end 102 of the flexible lighting assembly can terminate in a mechanical connector 210, such as a rigid hook, instead of in a headlight 180. All other elements of the lighting device 201 are described above with respect to the lighting device 1, and common reference numerals are used to refer to common elements. The mechanical connector 210 can be used to attach the lighting device 201 to an external support structure, such as a bracket, a protruding nail, or a cable.The mechanical connector 210 is not limited to a hook and can be any other mechanical connector that can be used to suspend the lighting device 1, such as a closed ring, a clip, a carabiner, a spring hook, a magnet, a clamp, a flexible wire, etc., depending on the requirements of the specific application. The mechanical connector 210 can be made of an opaque or a translucent material.

[0065] According to Fig. 24 and Fig. Reference numeral 25 includes a further alternative lighting device 301, the flexible lighting assembly 100 described above, and common reference numerals are used to refer to common elements. The lighting device 301 differs from the lighting devices 1, 201 described in earlier embodiments in that the disc-shaped housing 2 is omitted and replaced by an alternative housing 302. The housing 302 is elongated and flexible and provides support and protection for the flexible lighting assembly 100.

[0066] The housing 302 is a segmented, hinged assembly that is bendable about a single axis. Specifically, the housing 302 comprises individual hollow housing segments 304 connected in series to form an elongated, hollow, chain-like structure. Each housing segment 304 is connected to the adjacent housing segments 304 via hinge pins 305. Furthermore, the hollow interior of each housing segment 304 communicates with the cavity of the adjacent housing segments 304 to provide an internal passage 306 extending along the length of the housing 302. The flexible luminaire assembly is arranged within this internal passage 306. In some embodiments, each housing segment 304 is translucent. In other embodiments, each housing segment 304 is opaque and includes an opening or window 310 (in Fig. 25 shown), which allows light emitted from the flexible luminaire assembly 100 to exit the housing 302.

[0067] The housing segments 304 are hinged in parallel, allowing the housing 302 to be bent about a single axis. In this embodiment, the housing 302 is bendable about a "folding axis" 308, which runs parallel to the hinge pins 305 (e.g., the axis 308 runs parallel to the width direction of the housing 302). The housing 302 with the housing segments 304 hinged in series resists bending about axes orthogonal to the folding axis 308, including rotation. Furthermore, the housing 302 with the housing segments 304 hinged in series also withstands tensile loads (e.g., loads in a direction parallel to the center line 103 of the flexible luminaire assembly).

[0068] The lighting device 301 can include a power supply 312, which is electrically connected to one end of the housing 302. The power supply 312 can be permanently wired to the substrate 110 of the flexible lighting assembly 100 or alternatively detachably connected to it.

[0069] The lighting device 301 can be operated in a curved (shown), coiled, partially coiled, or extended (linearly arranged) configuration. Furthermore, the lighting device 301 can be rolled up for storage or convenient transport.

[0070] One or both ends of the housing 302 can terminate in mechanical connectors such as hooks, clamps, clips, mounting brackets 314 (shown), etc. Alternatively, one or both ends of the housing 302 can terminate in a secondary light source (not shown), for example, a headlight.

[0071] In the above with reference to Fig. The lighting device 1 described in Figures 1 to 23 comprises a housing 2, a stator 10, and a rotor 50 rotatably mounted on the stator 10. However, in some embodiments, a modified version of the rotor 50 can be used, which is fixed relative to the stator 10, and the flexible lighting assembly 100 can be manually wound around the coil 58. The modified rotor would still be translucent, making the housing 2 similar to that described in Figures 1 to 23. Fig. Figures 1 to 23 show an opaque side and a translucent side.

[0072] In the above with reference to Fig.In the housing 2 described in sections 1 to 23, the stator 10 includes the annular base 26, which serves as a stand. The base 26 is not limited to an annular shape. In some embodiments, for example, the base 26 may have a partially annular shape that acts as a hook, allowing the base 26 to serve as a stand in some environments and as a suspension device in others. In other embodiments, the base may include a magnet to facilitate connection with external structures. In further embodiments, the stator 10 itself may include a magnet to facilitate connection with external structures.

[0073] Selected illustrative embodiments of the lighting device are described in detail above. It is understood that only structures deemed necessary for explaining the lighting device have been described here. It is assumed that other conventional structures and those of additional and auxiliary components of the lighting device are known and understood by those skilled in the art. Furthermore, although working examples of the lighting device have been described above, the lighting device is not limited to these examples; various modifications can be made without deviating from the lighting device as presented in the claims.
