An embodiment of the present disclosure provides a lighting device including a light emitting module. According to different power or size, the light emitting module can have various specifications, and correspondingly, the lighting device can also have various specifications. 1A-1D are schematic diagrams of the three-dimensional structure of four kinds of lighting devices with different specifications, showing the light-emitting surface of the light-emitting module; Schematic diagram of the three-dimensional structure under the viewing angle, showing the back of the light-emitting module. The light-emitting surface of the light-emitting module is arranged opposite to the back.

As shown in FIGS. 1A-1D and FIGS. 2A-2D , a lighting 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 lighting device 10 . FIGS. 3A-3D are three-dimensional structural diagrams of light-emitting modules of the four lighting devices shown in FIGS. 1A-1D and 2A-2D, respectively, showing the backside of the light-emitting module. The light-emitting surface of the light-emitting module can refer to FIGS. 1A-1D . 4 is a schematic cross-sectional structural diagram of a light-emitting module in the lighting device of FIG. 1A , the upper side is the side where the light-emitting surface is located, and the lower side is the side where the back side is located.

As shown in FIG. 1A and FIG. 4 , the light-emitting module 100 includes a base 110 , a light-transmitting component 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. According to the number of the light emitting units 130 included in the light emitting module 100 , the light emitting module 100 is divided into different specifications. For example, as shown in FIGS. 1A , 2A and 3A, the light emitting module 100 includes one light emitting unit 130; as shown in FIGS. 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 FIGS. 1D, 2D and 3D, the light-emitting module 100 includes four light-emitting units 130.

It should be noted that, FIG. 3A-FIG. 3D schematically show the light-emitting module 100 with four different specifications, which does not mean that the light-emitting module 100 is limited to these four specifications, and may have other specifications. Not limited.

For example, as shown in FIGS. 1A-1D , each light-emitting unit 130 may include dozens of light-emitting elements 131 , and the dozens of light-emitting elements 131 are arranged in a certain pattern to form the light-emitting unit 130 . It should be noted that, each light-emitting unit 130 may also include one or other number of light-emitting elements 131 , which is not limited in the embodiment of the present disclosure.

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

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

For example, as shown in FIG. 4 , the light-transmitting component 120 includes at least one lens portion 121 . The lens portion 121 and the light-emitting element 131 are arranged in one-to-one correspondence. The light-transmitting component 120 is used to distribute the light emitted by the light-emitting element 131 . For example, the lamp bead of each LED corresponds to a lens part 121, and the lens part 121 can integrate the light emitted by the LED into parallel light or divergent light with a certain angle range, or other required light.

The base 110 plays a role of supporting the light-emitting element 130 and the light-transmitting component 120 . For example, as shown in FIG. 4 , the base 110 is located on the back side of the light emitting module 100 . The base 110 includes a bottom plate 111 and a side wall 112 . The light-transmitting component 120 is located on one side of the light-emitting surface 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 component 120 and the side wall of the base 110 to seal the light-emitting unit 130 in the accommodating space to prevent external water and oxygen from corroding the light-emitting element 131, thereby improving the service life of the light-emitting module . For example, the sealing member may be a sealing ring or a sealant. For example, the side wall of the light-transmitting component 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 between the two, so as to seal the above-mentioned accommodating space and seal the transparent The optical assembly and the base plate are fixed together. Based on the above configuration structure, the fixing between the light-transmitting component of the light-emitting module and the bottom plate does not require any screws, which improves the sealing effect and simplifies the process.

The multiple installation areas of the base 110 may be of an integrated structure. For example, in each light-emitting module, the base is an integral structure, and different areas on the base are set as the above-mentioned multiple installation areas.

For example, as shown in FIG. 3A , the light-emitting module 100 further includes a heat sink 140 , which is disposed on the back of the light-emitting module 100 (ie, the side of the base 110 away from the light-transmitting component 120 ) for dissipating the heat generated by the light-emitting element 131 spread out. The heat sink 140 includes a plurality of heat sinks 141 , and the heat sinks 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 FIGS. 1A-1D and FIGS. 2A-2D , the lighting device 10 further includes a mounting bracket 200 , a power supply component 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 power connector 150 may be a waterproof connector.

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

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

As shown in FIG. 5 and FIG. 6 , the lighting device 20 includes: a light-emitting module array 21 and a side 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 (towards the Z direction in the figure) and a back surface (the reverse of the Z-direction in the figure) opposite to each other, and the light-emitting surfaces of the at least two light-emitting modules 100 face the same On the side, the first direction X is parallel to the light emitting surface of the light emitting module 100 (the light emitting surface is parallel to the XY plane). The side beams 22 extend along the first direction X, and the side beams 22 are respectively connected with each light-emitting module 100 in the light-emitting module array 21 to combine at least two light-emitting modules 100 together. It should be noted that the three directions of X, Y, and Z are perpendicular to each other, forming a space rectangular coordinate system. For example, the array of light-emitting modules here is a one-dimensional array, that is, the light-emitting modules are arranged in one direction to form an array. Therefore, 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, that is, the light-emitting surfaces may be located in the same plane.

In the embodiments of the present disclosure, by arranging side beams and combining at least two light-emitting modules, lighting devices 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 a basic light-emitting module including four light-emitting units 130 as shown in FIG. 3D , that is, two basic light-emitting modules including four light-emitting units 130 are composed of eight light-emitting units. 130 of the light-emitting module array 21 . 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 two light-emitting units 130 and a basic light-emitting module including three light-emitting units 130 may form the light-emitting module array 21 including five light-emitting units 130, or two may include three light-emitting units 130. The basic light-emitting module of the unit 130 is composed of a light-emitting module array 21 including 6 light-emitting units 130, or a basic light-emitting module including three light-emitting units 130 and a basic light-emitting module including four light-emitting units 130. The light-emitting module array 21 of the seven light-emitting units 130 . Of course, the light emitting module array may also adopt other combinations or include more basic light emitting modules, and the embodiments of the present disclosure do not limit the specifications of the light emitting module array.

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

For example, as shown in FIG. 5 and FIG. 6 , the lighting device 20 is provided with two side beams 22 , and the two side beams 22 are respectively located at opposite side edges of the lighting device 20 in the second direction Y, and the second direction Y is parallel. on the light-emitting surface of the light-emitting module and perpendicular to the first direction X. Setting two side beams can increase the connection stability of the lighting module.

For example, as shown in FIG. 6 , the plane on which the heat sink 141 of the heat sink is located is substantially perpendicular to the first direction X, and the two ends of the heat sink in the second direction Y are respectively recessed along the Z direction to form a space between the two side beams. The structure is matched with the matching parts, and the side beams are connected to the matching parts at both ends of the heat sink.

For example, as shown in FIG. 5 and FIG. 7 , in the Z direction, after the side beam is connected to the matching part of the heat sink, the upper surface of the part between the two matching parts of the heat sink is roughly flush with the upper surface of the side beam .

For example, as shown in FIG. 6 , the side beam 22 is provided with a plurality of first connection holes 221 , the heat sink 141 or the base 110 is provided with first threaded holes 161 , and the side beam passes through the first connection holes 221 through a plurality of screws 231 Screw into the first threaded hole 161 to connect the side beam 22 with the matching portion of the heat sink.

For example, as shown in FIG. 6 , the lighting device 20 further includes: an inner gear plate 501 fixed on the side surface of the lighting device perpendicular to the first direction X; an outer gear plate 502 engaged with the inner gear plate 501 and fixed on the bracket portion 220 and screws 503, which pass through the bracket portion 220 and the outer chainring 502 and are connected with the inner chainring 501, and are configured to compress or loosen the teeth of the inner chainring 501 and the teeth of the outer chainring 502.

For example, the teeth of the outer chainring are distributed on the end face, and the teeth of the inner chainring are also distributed on the end face. And the internal toothed disc can be meshed with each other.

By arranging the outer toothed disc and the inner toothed disc which can be meshed with each other, the rotating connection between the bracket part and the light emitting module array can be realized. When the screw 503 is pressed, the teeth of the inner toothed disc 501 and the tooth of the outer toothed disc 502 are pressed tightly, the two toothed discs are meshed together, and the light-emitting module array is fixedly connected to the bracket; when the screw 503 is loosened, the inner toothed disc 501 The teeth of the outer tooth plate 502 are disengaged from the teeth of the external toothed plate 502. At this time, the light-emitting module array and the bracket can be rotated relative to each other. The light-emitting module and the bracket can be rotated to the required angle manually, and then tighten the screw 503. The adjusted angle is fixed. For example, as shown in FIG. 7 , the light-emitting module array can be rotated 360 degrees relative to the bracket portion.

For example, as shown in FIG. 6 , the mounting brackets are respectively connected with the light emitting module array on both sides along the X direction, and inner toothed discs and outer toothed discs are provided at the two connections.

For example, the inner gear plate 501 is fixedly arranged on the side wall of the light emitting module. The outer chainring 502 may be a casting chainring obtained by casting, or a sheet metal chainring obtained by stamping. Compared with the sheet metal chainrings, the casting chainrings have a larger thickness, higher structural strength, higher precision of the teeth, and higher meshing accuracy with the internal chainrings, which are suitable for lighting devices with heavier weight and higher precision requirements. ; The thickness of the sheet metal toothed plate is small, and the manufacturing cost is also small, which is suitable for lighting devices with small weight and low precision requirements, which is conducive to saving costs. Of course, the inner chainring and the outer chainring can also be manufactured by machining, which is not limited in the present disclosure. The type of external chainring can be selected according to product needs.

For example, as shown in FIG. 5 and FIG. 6 , the lighting device 20 further includes a power supply bracket 400 , which is connected to a side of the side beam 22 away from the light-emitting module array 21 . There are at least two connection points between the power support bracket 400 and each side beam 22 , and in the first direction X, each side of the two adjacent sides of the junction of the two adjacent light emitting modules 100 includes at least one connection point.

At the junction of the two light-emitting modules, the side beam is subjected to relatively large bending stress, and the junction is the weak position of the side beam. By arranging the connection points of the power supply bracket and the side beam on both sides of the junction, the power supply bracket can play the role of strengthening the structural strength of the side beam at the junction position, thereby enhancing the service life and safety of the lighting device.

There are various specific connection methods between the power support bracket and the side beam. For example, as shown in FIG. 5 , the power support 400 and the two side beams 22 have two connection points respectively, and the two connection points on each side beam are respectively located on the two light-emitting modules 100 , that is, the two connection points are respectively It is located on both sides of the junction of the two light-emitting module arrays. Of course, the embodiments of the present disclosure are not limited to this, as long as both light emitting modules have connection points, the structural strength of the side beam can be enhanced to a certain extent.

For example, when the light-emitting module array 21 includes three or more light-emitting modules 100 , a power supply bracket 400 may be provided at the junction 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 supply bracket 400 includes a plurality of first mounting holes 401 and a plurality of second mounting holes 402 . For the sake of clarity, FIG. 2E shows a schematic plan view of the arrangement of the first mounting holes 401 and the second mounting holes 402 . The first mounting holes 401 are elongated and extend in the third direction, and a plurality of first mounting holes 401 are arranged in the fourth direction; the second mounting holes 402 are elongated and extend in the fourth direction, and a plurality of second mounting holes 402 are elongated and extend in the fourth direction. The mounting holes 402 are arranged along the fourth direction. The third direction and the fourth direction cross each other and are both 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 component 300 , and the power supply component 300 is mounted on the power supply bracket 400 through the above-mentioned at least one first mounting hole 401 and at least one second mounting hole 402 . For example, as shown in FIG. 6 , the power supply unit 300 and the power supply bracket 400 are connected by screws 601 . For example, the power supply component 300 here may include a component for converting the commercial power into the power required by the lighting device or other control components.
