Specific Embodiments



[0021] Please refer to FIG. 1, which is a schematic exploded view of a three-dimensional structure of a lamp according to an embodiment of the present disclosure. The lamp includes a power source 10, a central light emitting module 20, and at least one edge light emitting module 30. In this embodiment, two edge light emitting modules 30 are taken as an example for illustration. However, this does not limit the present disclosure. It should be noted that the number of the edge light emitting module 30 in the present disclosure is greater than or equal to 1.

[0022] A venting hole 210 is provided on a center of the central light emitting module 20, the power source 10 is provided over the venting hole 210, and the power source 10 and the central light emitting module 20 are separated by a first gap D1. Here, a plurality of connecting posts 220 are provided on the central light emitting module 20 facing the power source 10, the plurality of connecting posts 220 are provided around a periphery of the venting hole 210, and the power source 10 is fixed on one end of the connecting posts 220 away from the central light emitting module 20 by screws, such that the power source 10 and the central light emitting module 20 are separated from each other by the first gap D1. It is known that the power source and the light emitting module of the lamp generate heat in the work, that is, the power source and the light emitting module are heat dissipation elements of the lamp respectively, and the two heat dissipation elements are isolated from each other in the embodiment of the disclosure, which helps to enhance the overall heat dissipation performance of the lamp.

[0023] In addition, each of the edge light emitting module 30 is provided around a periphery of the central light emitting module 20. Here, the shape of the at least one edge light emitting module 30 includes but is not limited to circular ring or rectangular-liked ring structure. Each of the edge light emitting modules 30 is provided around the periphery of the central light emitting module 20 and forms a concentric annulus or rectangular-liked concentric ring with the central light emitting module 20. The innermost edge light emitting module 30 of the at least one edge light emitting module 30 and the central light emitting module 20, and two adjacent edge light emitting modules 30 of the at least one edge light emitting module 30, are separated by a second gap respectively.

[0024] Specifically, in one case, each of the edge light emitting module 30 of the at least one edge light emitting module 30 and the central light emitting module 20 are in the same plane, and one edge light emitting module 30 of the at least one edge light emitting module 30 that is closest to the central light emitting module 20 and the central light emitting module 20 are separated by a second gap D2, and two adjacent edge light emitting modules 30 of the at least one edge light emitting module 30 are separated by a second gap D2. In other words, two adjacent components of the each edge light emitting module 30 of the at least one edge light emitting module and the central light emitting module 20 have the second gap D2 in a horizontal direction, as shown in FIG. 1. In another case, each edge light emitting module 30 of the at least one edge light emitting module 30 and the central light emitting module 20 are not in the same plane, that is, each edge light emitting module 30 of the at least one edge light emitting module 30 is distributed in a longitudinal direction of the lamp. Like the distribution shown by the exploded view of FIG. 1, each edge light emitting module 30 of the at least one edge light emitting module 30 and the central light emitting 20 are disposed a vertical direction. One edge light emitting module 30 of the at least one edge light emitting module 30 that is closest to the central light emitting module 20 and the central light emitting module 20 are separated by a second gap D2 in height. In other words, two adjacent components of the each edge light emitting module 30 of the at least one edge light emitting module and the central light emitting module 20 have the second gap D2 in height. Here, the second gap D2 is illustrated in two directions (for example, horizontal and vertical). However, in actual application, the second gap D2 may be set according to only one direction, and may also be set both in the two directions at the same time.

[0025] In the above design, by separating the power source 10, the central light source module 20, and each edge light emitting module 30 of the at least one edge light emitting module 30 from each other, the air around the lamp may flow between the first gap D1 and the second gap D2, and perform heat exchange with the power source 10, the central light emitting module 20, and the edge light emitting module 30, thereby achieving independent heat dissipation of a plurality of heat generating individuals, and improving the overall heat dissipation performance of the lamp.

[0026] In addition, it should be noted that the at least one edge light emitting module 30 in the present disclosure can be expanded in an infinite manner, that is, on the basis of ensuring the overall heat dissipation performance of the lamp, the light emitting area of the lamp can be improved. In other words, the technical problem that the heat dissipation performance is still poor in the LED high shed lamp with large light emitting area at the present stage is solved. Referring to FIG. 2, in one embodiment of the present disclosure, each edge light emitting module 30 of the edge light emitting module 30 and the central light emitting module 20 are in the same plane, that is, the light emitting surfaces of the each edge light emitting module 30 of the at least one edge light emitting module 30 and the central light emitting module 20 are in the same plane. One edge light emitting module 30 of the at least one edge light emitting module 30 that is closest to the central light emitting module 20 and the central light emitting module 20 are separated by a second gap D2, and two adjacent edge light emitting modules 30 of the at least one edge light emitting module 30 are separated by a second gap D2, that is, two adjacent components of the each edge light emitting module 30 of the at least one edge light emitting module and the central light emitting module 20 have the second gap D2 in a horizontal direction.

[0027] Here, a first connecting plate 310 is provided on a side of the each edge light emitting module of the at least one edge light emitting module close to the central light emitting module, and the first connecting plate 310 is used to connect the central light emitting module or a side of the each light emitting module 30 away from the central light emitting module 20. Specifically, the first connecting plate 310 is provided along a periphery on a side of the each edge light emitting module 30 close to the central light emitting module 20, and is connected to the central light emitting module 20 or a side of the each edge light emitting module 30 away from the central light emitting module 20 by a screw, to realize connections between the central light emitting module 20 and the innermost edge light emitting module 30 of the at least one edge light emitting module 30, and between two adjacent edge light emitting modules 30 of the at least one edge light emitting module 30.

[0028] Referring to FIG. 3, in another embodiment of the present disclosure, each edge light emitting module 30 of the edge light emitting module 30 is located at a side of the central light emitting module 20 depart from the power source 10, and in the direction of the power source 10 to the central light emitting module 20.

The each edge light emitting module 30 of the at least one edge light emitting module 30 and the central light emitting module 20 are respectively disposed in a vertical direction. The each edge light emitting module 30 of the at least one edge light emitting module 30 that is closest to the central light emitting module 20 and the central light emitting module 20 are separated by a second gap D2 in height, and two adjacent edge light emitting modules 30 of the at least one edge light emitting module 30 are separated by a second gap D2 in height. In other words, two adjacent components of the each edge light emitting module 30 of the at least one edge light emitting module and the central light emitting module 20 have the second gap D2 in height.

[0029] Here, a second connecting plate 320 is provided on a side of the each edge light emitting module 30 of the at least one edge light emitting module 30 close to the central light emitting module 20, and a top of the second connecting plate 320 is used to connect a bottom of the central light emitting module 20 or a bottom of the a side of the each edge light emitting module 30 away from the central light emitting module 20.

In other preferred embodiments of the present disclosure, in order to increase the compactness of the closed space 410, a sealing ring 420 is provided between the heat sink 40 and the lens 60. Here, the sealing ring 420 is generally made of elastic material, such as a silica gel or the like. Moreover, since each edge light emitting module 30 of the edge light emitting module 30 and the central light emitting module 20 are annular structures, the sealing ring 420 has an inner ring and an outer ring, which are respectively located on an inner side and an outer circumference of the heat sink 40, so that the compactness at the inner and outer openings of the closed space 410 is ensured.
