The embodiment of the application provides a lamp.

Referring to fig. 3 to 5, in one embodiment, the lamp includes a lamp housing 100, a first diffusion cover 200, a light source assembly 300, and a second diffusion cover 400. The first diffusion cover 200 and the lamp housing 100 are matched, spliced and enclosed to form an installation cavity; the light source assembly 300 is arranged in the installation cavity, the light source assembly 300 comprises a substrate 310 and a plurality of light sources 320 arranged on the substrate 310, and the substrate 310 and the inner wall surface of the first diffusion cover 200 enclose a first sub-cavity 120; the second diffusion cover 400 is built in the first sub-chamber 120, the second diffusion cover 400 has a light source chamber 410 opened toward the base plate 310, the second diffusion cover 400 is connected to the base plate 310, and all the light sources 320 are built in the light source chamber 410.

It should be noted that the technical solution of the present application is particularly suitable for flat-type bulb lamps, but the technical solution of the present application can also be suitable for other types of lamps with suitable structures. In this embodiment, the light sources 320 are specifically LED lamp beads, and the plurality of light sources 320 are compactly distributed on the substrate 310 and completely covered by the second diffusion cover 400, and the first diffusion cover 200 completely covers the second diffusion cover 400 and the substrate 310. The first diffusion cover 200, the second diffusion cover 400 and the lamp housing 100 may be made of a plastic material by injection molding, for example, but not limited to, the first diffusion cover 200 and the second diffusion cover 400 may be made of a PC (Polycarbonate) material, so as to reduce the cost.

Based on the structural design, in the embodiment, since the second diffusion cover 400 is disposed in the first diffusion cover 200, and the second diffusion cover 400 covers all the light sources 320, when the lamp emits light, the light emitted from the light sources 320 is firstly diffused by the second diffusion cover 400 to emit light, the light emitting angle is increased, then the light with the increased light emitting angle is diffused by the first diffusion cover 200 to emit light, the light emitting angle is further increased, the average light emitting angle is greater than or equal to 200 degrees, and the effect of uniform light spots is achieved on the surface of the first diffusion cover 200. In other words, in the technical solution of the present application, besides simple structure, convenient assembly and easy realization of automated production, the light source 320 can be compactly distributed in the light source cavity 410 of the second diffusion cover 400, and the light emitted by the light source can be diffused by the first diffusion cover 200 and the second diffusion cover 400 in sequence, so as to effectively increase the light emitting angle.

Referring to fig. 1 to 3, in the present embodiment, the outer surface of the first diffusion cover 200 is a flat arc surface, and the second diffusion cover 400 is tapered in a direction away from the lamp housing 100. Certainly, in other embodiments, the first diffusion cover 200 and the second diffusion cover 400 may be disposed in other shapes, but in this embodiment, the optimized shape design of the first diffusion cover 200 and the second diffusion cover 400 may obtain a better light diffusion effect, which is further beneficial to further increase the light emitting angle of the lamp. Further, referring to fig. 3 to 5, in the present embodiment, the outer surface of the second diffusion cover 400 is an arc surface tapering in the direction away from the lamp housing 100, so that the appearance is more beautiful, and by the effect of the tapering arc surface, a better light diffusion effect can be obtained, and the light emitted by the first diffusion cover 200 is more uniform and softer.

Further, as shown in fig. 3, in the present embodiment, a gap is provided between one end of the second diffusion cover 400 away from the lamp housing 100 and the inner wall surface of the first diffusion cover 200. Specifically, the height of the second diffusion cover 400 is about 0.8 times the height of the first diffusion cover 200, i.e., the second diffusion cover 400 is slightly shorter than the first diffusion cover 200. It can be understood that the gap between the inner wall surfaces of the second diffusion cover 400 and the first diffusion cover 200 is not only beneficial to the heat dissipation of the light source 320, but also can avoid the occurrence of uneven light emission of the lamp due to the fact that the light at the top end of the second diffusion cover 400 is too concentrated after contacting the first diffusion cover 200.

It should be noted that in the present embodiment, the haze of the first diffusion cover 200 is smaller than that of the second diffusion cover 400. It can be understood that, on the premise that the lamp maintains the present appearance, the light emitting angle is increased by mainly using the second diffusion cover 400 which is tapered in the direction away from the lamp housing 100 to fold and scatter the light of the LED light source 320 to the side wall of the first diffusion cover 200, and then the first diffusion cover 200 uniformly diffuses the light again. If the haze of the first diffusion cover 200 is greater than that of the second diffusion cover 400, that is, if the haze of the first diffusion cover 200 is increased, the high-angle light generated by the second diffusion cover 400 is scattered again in the local space formed between the second diffusion cover 400 and the first diffusion cover 200 for many times, which results in partial loss of the high-angle light emitted from the second diffusion cover 400; if the haze of the first diffusion cover 200 is reduced, the light mixing capability in the local space is reduced, and instead, the high-angle light generated by the second diffusion cover 400 can be better protected, and the light loss is reduced.

Further, referring to fig. 3 to 5, in the present embodiment, the second diffusion cover 400 is further provided with a positioning leg 420 and a connecting buckle 430, the positioning leg 420 and the connecting buckle 430 are both formed by extending from the open edge of the second diffusion cover 400 at intervals toward the lamp housing 100, the positioning leg 420 and the connecting buckle 430 are oppositely arranged at intervals, and the base plate 310 is provided with a positioning hole 311 for the positioning leg 420 to be adapted and inserted, and a buckle hole 312 for the connecting buckle 430 to be adapted and inserted. In the actual assembling process, the positioning legs 420 can be partially inserted into the positioning holes 311, and then the connecting fasteners 430 are fastened into the fastening holes 312, so that the assembling process is very convenient, and the second diffusion cover 400 can be limited and fixed in the front-back left-right direction through the positioning legs 420 and the connecting fasteners 430 which are arranged at intervals.

Further, in this embodiment, the open edge of the second diffusion cover 400 is further provided with a connection lug 440, and the connection lug 440 is provided with a screw hole. Specifically, after the positioning legs 420 and the connecting fasteners 430 are assembled, the connecting lugs 440 are attached to the surface of the substrate 310, and then the second diffusion cover 400 is more firmly mounted on the substrate 310 through screws or other connecting members passing through the screw holes, so that the second diffusion cover is not easily loosened and removed. Here, the connecting lug 440 is preferably disposed adjacent to the positioning leg 420, and the connecting lug 440, the positioning leg 420 and the connecting buckle 430 are matched, so that screw assembly can be reduced as much as possible on the premise of ensuring stable connection, and the assembly convenience of the lamp can be further improved.

Referring to fig. 3 to 5, in the present embodiment, the light source assembly 300 further includes a control module 330, the control module 330 is integrally mounted on the substrate 310, and the control module 330 is located at the periphery of the second diffusion cover 400. Specifically, in order to reduce the occupied space, a notch is formed on one side of the substrate 310, and the control module 330 is similar to an L shape, and a partial region thereof is overlapped and connected with the substrate 310. Here, the notch of the substrate 310 is beneficial for heat dissipation of the control module 330 and connection between the control module 330 and the driving module 600. In addition, in this embodiment, in consideration of spatial integration, the substrate 310 is provided with the intelligent control module 330, so that the LED light sources 320 are not arranged in the middle, but the scheme of the multi-layer diffusion cover in the present application can not only increase the light emitting angle, but also can well solve the problem of uneven light distribution at two sides of the first diffusion cover 200 caused by the fact that the LED light sources 320 slightly deflect to one side on the substrate 310.

Further, as shown in fig. 3 and 5, in the present embodiment, the lamp further includes a heat dissipation member 500, and the substrate 310 is fixed on the heat dissipation member 500. By such a design, the substrate 310 can be located close to the heat sink 500, and the light source 320 can not be well dissipated. Specifically, the heat dissipation member 500 is preferably made of aluminum with good heat dissipation, and is shaped like a disc, and the outer edge thereof can be overlapped with the inner wall of the lamp housing 100 and clamped inside the lamp housing 100. A plurality of screw holes are formed in the vacant regions of the substrate 310, and the substrate 310 may be detachably coupled to the heat sink 500 by screws passing through the screw holes. However, the design is not limited thereto, and in other embodiments, the substrate 310 and the heat sink 500 may be detachably connected by other methods such as clamping.

Further, as shown in fig. 3 and 5, the heat dissipation element 500 and the inner wall surface of the lamp housing 100 form a second sub-cavity 130, the lamp further includes a driving module 600, the driving module 600 is disposed in the second sub-cavity 130, and two connecting ends of the driving module 600 are connected to the light source 320 and the control module 330 respectively after penetrating through the heat dissipation element 500, so that driving control of the lamp can be achieved, and the driving module 600 can be vertically installed to save space. In addition, a lamp cap 700 is further disposed at an end of the lamp housing 100 away from the first diffusion cover 200, one end of the lamp cap 700 is connected to an external power source, and the other end is connected to the driving module 600, and the driving module 600 provides electric energy for the control module 330 and the light source 320.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
