The lighting device can be used as a projector or a lamp with other purposes.

The lighting device provided by the embodiment of the disclosure is described in detail below with reference to the accompanying drawings.

An embodiment of the present disclosure provides an illumination device including a light emitting module. The light emitting module may have various specifications according to the difference of power or size, and accordingly, the lighting device may also have various specifications. FIGS. 1A-1D are schematic three-dimensional structures of four different specifications of lighting devices, showing the light-emitting surface of the light-emitting module; fig. 2A to 2D are schematic three-dimensional structures of the four lighting devices shown in fig. 1A to 1D, respectively, at a further viewing angle, and illustrate the back surface of the light emitting module. The light emitting surface and the back surface of the light emitting module are arranged oppositely.

As shown in fig. 1A to 1D and fig. 2A to 2D, an illumination device 10 provided by an embodiment of the present disclosure includes a light emitting module 100, and the light emitting module 100 is configured as a light emitting source of the illumination device 10. Fig. 3A to 3D are schematic three-dimensional structures of the light emitting modules of the four lighting devices shown in fig. 1A to 1D and fig. 2A to 2D, respectively, and show the back of the light emitting module. Fig. 1A to 1D show the light emitting surface of the light emitting module. Fig. 4 is a schematic cross-sectional view of the light emitting module in the lighting device of fig. 1A, in which the upper side is the side where the light emitting surface is located, and the lower side is the side where the back surface is located.

As shown in fig. 1A and 4, the light emitting module 100 includes a base 110, a light transmissive member 120, and at least one light emitting unit 130. Each light emitting unit 130 includes at least one light emitting element 131.

The number of light emitting units 130 included in the light emitting module 100 affects the power and size of the light emitting module. The light emitting module 100 is divided into different specifications according to the number of the light emitting units 130 included in the light emitting module 100. For example, as shown in fig. 1A, 2A and 3A, the light emitting module 100 includes a light emitting unit 130; as shown in fig. 1B, 2B and 3B, the light emitting module 100 includes two light emitting units 130; as shown in fig. 1C, 2C and 3C, the light emitting module 100 includes three light emitting units 130; as shown in fig. 1D, 2D and 3D, the light emitting module 100 includes four light emitting units 130.

It should be noted that fig. 3A to fig. 3D schematically illustrate four light emitting modules 100 with different specifications, and do not indicate that the light emitting module 100 is limited to these four specifications, and other specifications may also be provided, which is not limited in this disclosure.

For example, as shown in fig. 1A to 1D, each light emitting unit 130 may include tens of light emitting elements 131, and the tens of light emitting elements 131 are arranged in a certain pattern to constitute the light emitting unit 130. It should be noted that each light emitting unit 130 may also include one or another number of light emitting elements 131, which is not limited in this embodiment of the disclosure.

For example, in some examples, as shown in fig. 1A-1D, the light-emitting unit 130 has a substantially rectangular shape.

For example, the light emitting element 131 may be a light emitting diode, and may emit white light or colored light.

For example, as shown in fig. 4, the light transmission member 120 includes at least one lens portion 121, the lens portions 121 are disposed in one-to-one correspondence with the light emitting elements 131, and the light transmission member 120 is configured to distribute light emitted by the light emitting elements 131. For example, each light emitting diode bead corresponds to one lens portion 121, and the lens portion 121 can integrate light emitted by the light emitting diode into parallel light or divergent light with a certain included angle range, or other required light.

The base 110 functions to support the light emitting element 130 and the light transmissive member 120. For example, as shown in fig. 4, the base 110 is located on the back side of the light emitting module 100, and the base 110 includes a bottom plate 111 and a side wall 112, the bottom plate and the side wall enclose a receiving groove, and an opening of the receiving groove faces the light emitting surface side. The light-transmitting element 120 is located on a light-emitting surface side of the light-emitting module 100. The light-transmitting component 120 is disposed opposite to the bottom plate of the base 110 with a certain distance therebetween to form an accommodating space, and the light-emitting unit 130 is disposed in the accommodating space. For example, a sealing member is disposed between the light-transmitting member 120 and the sidewall of the base 110 to seal the light-emitting unit 130 in the accommodating space, so as to prevent the light-emitting element 131 from being corroded by external water and oxygen, thereby prolonging the service life of the light-emitting module. For example, the sealing member may be a sealing ring or sealant. For example, the side surface of the light-transmitting member 120 is opposite to the side wall of the bottom plate in a direction substantially parallel to the bottom plate, and at least one of a sealing ring and a sealant may be disposed therebetween, so as to seal the accommodating space and fix the light-transmitting member and the bottom plate together. Based on the configuration structure, no screw is needed for fixing the light-emitting module light-transmitting component and the bottom plate, the sealing effect is improved, and the process is simplified.

For example, as shown in fig. 1B-1D, for a light emitting module 100 including a plurality of light emitting units 130, correspondingly, the base 110 includes a plurality of mounting regions, the light transmitting member 120 forms a plurality of accommodating spaces with the plurality of mounting regions, and the plurality of light emitting units 130 correspond to the plurality of accommodating spaces one to one. The plurality of mounting regions of the base 110 may be a unitary structure. For example, in each light emitting module, the base is a unitary structure, and different regions on the base are provided as the plurality of mounting regions.

For example, as shown in fig. 3A, the light emitting module 100 further includes a heat sink 140 disposed on the back side of the light emitting module 100 (i.e., the side of the base 110 away from the light transmissive member 120) for dissipating heat generated by the light emitting element 131. The heat sink 140 includes a plurality of heat dissipation fins 141, which can increase the heat dissipation area and improve the heat dissipation effect. For example, the heat sink 140 may be integrally provided with the base 110.

As shown in fig. 1A to 1D and fig. 2A to 2D, the lighting device 10 further includes a mounting bracket 200, a power supply part 300, and a power supply bracket 400.

As shown in fig. 2A, the mounting bracket 200 includes a mounting plate 210 and a bracket portion 220 connected to the mounting plate 210. The bracket portion 220 is rotatably coupled to the light emitting module 100, and the mounting plate 210 is configured to be fixed at a mounting position. The mounting plate 210 is used for fixing the lighting device, and the bracket portion 220 can adjust the orientation of the light emitting surface of the light emitting module, so as to change the irradiation angle of the lighting device.

As shown in fig. 2A, the power bracket 400 is connected to the rear surface of the light emitting module 100. The power supply part 300 is mounted on the power supply bracket 400. As shown in fig. 3A, the light emitting module 100 further includes a power connector 150, one end of the power connector 150 is connected to the light emitting unit 130, and the other end is used for connecting to the power component 300. The power connector 150 may be a waterproof connector.

The light emitting module including 1-4 light emitting units can be used as a basic light emitting module to form a lighting device. The light emitting modules described above may also be used in combination to form an array of light emitting modules to form a lighting device with more power specifications, as described further below.

An embodiment of the present disclosure provides another lighting device, fig. 5 is a schematic three-dimensional structure diagram of the lighting device, fig. 6 is a schematic exploded structure diagram of the lighting device shown in fig. 5, and fig. 7 is a view of the lighting device in fig. 6 along an X direction.

As shown in fig. 5 and 6, the lighting device 20 includes: an array of light modules 21 and a border beam 22. The light emitting module array 21 includes at least two light emitting modules 100 arranged along the first direction X. Each of the at least two light emitting modules 100 includes a light emitting surface (facing the Z direction in the drawing) and a back surface (facing the reverse direction of the Z direction in the drawing) opposite to each other, and the light emitting surfaces of the at least two light emitting modules 100 face the same side, and the first direction X is parallel to the light emitting surfaces of the light emitting modules 100 (the light emitting surfaces are parallel to the XY plane). The edge beam 22 extends along the first direction X, and the edge beam 22 is connected to each of the light emitting modules 100 in the light emitting module array 21 to combine at least two light emitting modules 100. It should be noted that X, Y, Z are perpendicular to each other to form a rectangular spatial coordinate system. For example, the array of light emitting modules herein is a one-dimensional array, that is, the light emitting modules are arranged in one direction to form an array. Thus, the array here can also be regarded as a row of light emitting modules or a column of light emitting modules.

For example, the light emitting surfaces of the two light emitting modules 100 are flush, i.e., the light emitting surfaces may be located in the same plane.

In the embodiment of the disclosure, by arranging the edge beam, at least two light-emitting modules are combined together, and the lighting device with various power specifications can be quickly and stably formed according to actual needs.

For example, the light emitting module 100 shown in fig. 5 is the basic light emitting module including 4 light emitting units 130 shown in fig. 3D, that is, two basic light emitting modules including 4 light emitting units 130 form a light emitting module array 21 including 8 light emitting units 130. Of course, the light emitting module array 21 may also be composed of light emitting modules 100 of other specifications. For example, a basic light emitting module including 2 light emitting units 130 and a basic light emitting module including 3 light emitting units 130 may form a light emitting module array 21 including 5 light emitting units 130, two basic light emitting modules including 3 light emitting units 130 may form a light emitting module array 21 including 6 light emitting units 130, or a basic light emitting module including 3 light emitting units 130 and a basic light emitting module including 4 light emitting units 130 may form a light emitting module array 21 including 7 light emitting units 130. Of course, the light emitting module array may also adopt other combination manners or include more basic light emitting modules, and the embodiment of the disclosure does not limit the specification of the light emitting module array.

For example, as shown in fig. 5 and 6, the edge beam 22 is located on the back surface of the light emitting module 100, and at least partially overlaps the light emitting module 100 in a direction (Z direction) perpendicular to the light emitting surface.

For example, as shown in fig. 5 and 6, the lighting device 20 is provided with two edge beams 22, and the two edge beams 22 are respectively located at two opposite side edges of the lighting device 20 in a second direction Y, which is parallel to the light emitting surface of the light emitting module and perpendicular to the first direction X. The connection steadiness of setting up two boundary beams can increase the luminous module.

For example, as shown in fig. 6, the plane of the heat sink fins 141 is substantially perpendicular to the first direction X, and both ends of the heat sink fins in the second direction Y are recessed in the Z direction, respectively, to form engaging portions that engage with the structures of two side beams connected to the engaging portions at both ends of the heat sink fins.

For example, as shown in fig. 5 and 7, when the edge beam is attached to the mating portion of the heat sink in the Z-direction, the upper surface of the portion of the heat sink between the two mating portions is substantially flush with the upper surface of the edge beam.

For example, as shown in fig. 6, the edge beam 22 is provided with a plurality of first connection holes 221, the heat sink 141 or the base 110 is provided with first screw holes 161, and the edge beam is screwed into the first screw holes 161 through the first connection holes 221 by a plurality of screws 231 to connect the edge beam 22 with the mating portion of the heat sink.

For example, as shown in fig. 6, the lighting device 20 further includes: an inner toothed disc 501 fixed to a side surface of the lighting device perpendicular to the first direction X; an outer toothed disc 502 engaged with the inner toothed disc 501 and fixed to the support portion 220; and a screw 503 passing through the bracket portion 220 and the outer toothed plate 502 and connected to the inner toothed plate 501, and configured to press or loosen the teeth of the inner toothed plate 501 and the teeth of the outer toothed plate 502.

For example, the teeth of the outer toothed disk are distributed over the end faces, the teeth of the inner toothed disk are also distributed over the end faces, the two end faces provided with teeth are arranged opposite to each other, i.e. the teeth of the outer toothed disk are arranged opposite to the teeth of the inner toothed disk, and the outer toothed disk and the inner toothed disk can mesh with each other.

The outer fluted disc and the inner fluted disc which can be meshed with each other are arranged, so that the support part can be rotationally connected with the light-emitting module array. When the screw 503 is pressed tightly, the teeth of the inner fluted disc 501 and the teeth of the outer fluted disc 502 are pressed tightly, the two fluted discs are meshed together, and the light-emitting module array is fixedly connected with the bracket part; when the screws 503 are loosened, the teeth of the inner toothed plate 501 and the teeth of the outer toothed plate 502 are disengaged, at the moment, the light emitting module array and the bracket portion can rotate relatively, the light emitting modules and the bracket portion can be rotated to a required angle in a manual mode, then the screws 503 are screwed, and the adjusted angle is fixed. For example, as shown in fig. 7, the light emitting module array may realize 360 degrees rotation with respect to the bracket portion.

For example, as shown in fig. 6, the mounting bracket is connected to the light emitting module array at two sides along the X direction, and an inner gear and an outer gear are disposed at the two connections.

For example, the inner toothed disc 501 is fixedly disposed on the sidewall of the light module. Outer toothed disc 502 may be a cast toothed disc, obtained by casting; the gear plate can also be a metal plate gear plate and is obtained by stamping. Compared with a sheet metal fluted disc, the cast fluted disc has larger thickness, higher structural strength, higher precision of teeth, higher meshing precision with an inner fluted disc, and is suitable for lighting devices with larger weight and higher precision requirement; the thickness of panel beating fluted disc is less, and manufacturing cost is also less, is applicable to the lighting device that weight is less and require less to the precision, is favorable to practicing thrift the cost. Of course, the inner and outer toothed discs may also be manufactured by machining, which is not limited in this disclosure. The type of the external gear disc can be selected according to the product requirement.

For example, as shown in fig. 5 and 6, the lighting device 20 further includes a power bracket 400 connected to a side of the edge beam 22 away from the light emitting module array 21. At least two connection points are formed between the power bracket 400 and each of the edge beams 22, and each of two sides of the boundary between two adjacent light emitting modules 100 includes at least one connection point in the first direction X.

At the juncture of two light-emitting modules, the bending stress that the boundary beam received is great, and this juncture is the weak position of boundary beam. The connecting points of the power supply bracket and the boundary beam are respectively arranged on two sides of the junction, so that the power supply bracket can play a role in strengthening the structural strength of the boundary beam at the junction, and the service life and the safety of the lighting device are enhanced.

The specific connection mode of the power supply bracket and the boundary beam can be various. For example, as shown in fig. 5, the power bracket 400 has two connection points with the two side beams 22, and the two connection points on each side beam are located on the two light emitting modules 100, i.e. the two connection points are located on two sides of the intersection of the two light emitting module arrays. Of course, the embodiments of the present disclosure are not limited thereto, and the function of enhancing the structural strength of the edge beam can be performed to some extent as long as there are connection points on both the two light emitting modules.

For example, when the light emitting module array 21 includes three or more light emitting modules 100, the power bracket 400 may be disposed at an interface of every two adjacent light emitting modules 100.

The structure of the power supply bracket can be referred to fig. 2A. For example, as shown in fig. 2A, the power bracket 400 includes a plurality of first mounting holes 401 and a plurality of second mounting holes 402. For clarity, fig. 2E shows a schematic plan arrangement of the first mounting holes 401 and the second mounting holes 402. The first mounting holes 401 are long and extend along the third direction, and the plurality of first mounting holes 401 are arranged along the fourth direction; the second mounting holes 402 are elongated and extend along the fourth direction, and the plurality of second mounting holes 402 are arranged along the fourth direction. The third direction and the fourth direction are mutually crossed and are parallel to the light emitting surface (XY plane) of the light emitting module. For example, the third direction is parallel to the X direction, and the fourth direction is parallel to the Y direction, but embodiments of the present disclosure are not limited thereto.

The lighting device 20 further includes a power supply part 300, and the power supply part 300 is mounted on the power supply bracket 400 through the at least one first mounting hole 401 and the at least one second mounting hole 402. For example, as shown in fig. 6, the power supply part 300 and the power supply bracket 400 are connected by a screw 601. For example, the power supply unit 300 may include a unit for converting commercial power into power required for the lighting device or other control unit.

According to the lighting device in the embodiment of the present disclosure, the lighting device can be adapted to power supply components with different specifications and different sizes. Through setting up a plurality of first mounting holes and a plurality of second mounting hole, when installing power supply unit to power support on, through making power supply unit simply slide along third direction or fourth direction for power support, can make the connecting hole on the power supply unit of equidimension all can align with first mounting hole or second mounting hole on the power support more easily to can reduce power supply unit and power support cooperation precision, increase the installation convenience.

In the power supply bracket according to fig. 2E, three rows of mounting holes are provided, including two rows of first mounting holes on both sides and one row of second mounting holes in the middle. However, embodiments according to the present disclosure are not limited thereto, and may include a column of first mounting holes and a column of second mounting holes; alternatively, a plurality of rows of first mounting holes and a plurality of rows of second mounting holes may be included. For example, the first and second mounting hole columns may be alternately arranged such that the first and second mounting hole columns are adjacent to each other.

For example, as shown in fig. 6, the power supply unit 300 includes a plurality of power lines 301 respectively connected to the power connectors 150 of at least two light emitting modules.

Fig. 8 is an enlarged schematic view of the structure at I in fig. 7. As shown in fig. 8, the edge beam 22 has a double-layered structure. The edge beam 22 includes a first connecting plate 222 and a second connecting plate 223, and the first connecting plate 222 and the second connecting plate 223 may be disposed in parallel. The first connecting plate 222 and the second connecting plate 223 have a gap therebetween, and are connected by a reinforcing rib. The reinforcing ribs include a first reinforcing rib 241, a second reinforcing rib 242, a third reinforcing rib 243, and a fourth reinforcing rib 244, which are sequentially arranged in the Y direction. The first 241, second 242, third 243 and fourth 244 beads all enhance the resistance to force of the sill 22.
