Of course, in some other embodiments, the face ring portion 120 may also be configured for lamp body 1 mounting.

Referring to fig. 2 and 3, the mounting portion 130 is connected to the housing 100 for mounting the clamp spring 300. For a description of the circlip 300, please refer to the following, which is not described herein.

Referring to fig. 1, the mounting portion 130 is formed of an additional sidewall disposed on the sidewall 112. For example, the additional sidewall is formed with a mounting finger and a T-shaped groove for positioning the clip spring 300.

Referring to fig. 1 to 4, after the assembly is completed, the side wall 112 and the bottom wall 111 of the housing 100 are respectively in contact with the optical element 210, so that heat generated by the lighting module 200 can be dissipated, and the influence on the service quality and the service life of the lighting module 200 due to an over-high temperature in the housing 100 can be avoided.

As shown in fig. 1, 2 and 3, the illumination module 200 includes an optical element 210, a diffusing element 220 and an optoelectronic module 230. The optical element 210 is made of a reflective plastic, and a part of the light emitted by the optoelectronic module 230 enters the diffusing element 220 after being reflected by the inner surface of the optical element 210, so that the utilization rate of the light emitted by the optoelectronic module 230 is increased.

As shown in fig. 4 and 5, the optical element 210 has opposite mounting ends 211 and light exit ends 212. The mounting end 211 is a closed end, and the light-emitting end 212 is open.

As shown in fig. 4 and 5, in the present embodiment, the optical element 210 has a receiving cavity 2100 and a light emitting end 212 communicating with the receiving cavity 2100.

Referring to fig. 1, fig. 2 and fig. 3, in this embodiment, the optical element 210 is in a hollow truncated cone shape as a whole, and the optical element 210 includes a mounting bottom plate 213 and a reflective sidewall 214, the reflective sidewall 214 is disposed along an edge of the mounting bottom plate 213, the mounting bottom plate 213 and the reflective sidewall 214 together form the receiving cavity 2100 and the light emitting end 212, and the light emitting end 212 corresponds to the mounting bottom plate 213.

Referring to fig. 2, in order to electrically connect the optoelectronic module 230 to an external power source, a lead channel 202 is disposed on a side of the optical element 210 facing the receiving cavity 101, allowing a lead between the optoelectronic module 230 and the external power source to pass through for guiding the lead, and achieving the purpose of pressing the lead and preventing the lead from being pulled.

In a preferred embodiment, the mounting base plate 213 is provided with a lead channel 202, and the lead channel 202 penetrates through the thickness of the mounting base plate 213 to allow a lead wire between the optoelectronic module 230 and an external power source to pass through.

Further, the lead channel 202 protrudes from the outer surface of the mounting base plate 213 (i.e., the surface of the mounting base plate 213 away from the accommodating cavity), so that the lead can be led out of the housing 100, thereby preventing the lead from contacting the housing 100, and improving the reliability and insulation of the lamp.

Referring to fig. 1, when the lighting module 200 is assembled in the housing 100, the lead channel 202 extends into the through hole 103 and further protrudes to be flush with the through hole 103 or flush with the through hole 103. The arrangement is that, on one hand, the lead wire is separated from the shell 100 by the lead channel 202, so that the lead wire is prevented from contacting the shell 100, and the metal shell is prevented from being electrified; on the other hand, referring to fig. 1 and fig. 3, the corresponding relationship between the lead channel 202 and the through hole 103 (referring to fig. 1 and fig. 3) can enable the lighting module 200 and the housing 100 to be aligned more quickly during assembly.

Referring to fig. 5, a heat-fusible column 215 is disposed on a surface of the mounting base plate 213 facing the receiving cavity 2100. The heat-melting column 215 is used for assembling, positioning and heat-melting fixing the photovoltaic module 230 and the mounting base plate 213.

When mounting, the heat-fusible column 215 of the mounting base plate 213 is first inserted through the through hole of the photovoltaic module 230. The rear portion of the heat-fusible column 215 is then heated by heat-fusing, so that the mounting base plate 213 is fixed to the photovoltaic module 230 through the heat-fusible column 215.

In particular, in order to improve the insulation reliability of the lighting module, the optical element may be made of an insulating material. Such as a plastic optical element.

In other embodiments, the back surface of the optoelectronic module 230 may also be used as the mounting base 213 of the optical element 210, and then the optoelectronic module 230 is directly welded to the reflective sidewall 214. Generally, the mounting base plate 213 may be a part of the whole structure of the optical element 210, or may be a separate component welded to the optical element 210, or may use the back surface of the optoelectronic module 230 as the mounting base plate 213, which is more beneficial to the light-weight design of the lighting module 200.

Referring to fig. 1, 2, 4 and 5, the diffusing element 220 is disposed at the light-emitting end 212 of the optical element 210, and the diffusing element 220 is fixed on the optical element 210.

Further, the diffusing element 220 can seal the light exit end 212 of the optical element 210. Referring to fig. 1 and fig. 2, in this case, the diffusing element 220 and the optical element 210 together form a closed package 10, and the package 10 can encapsulate the entire optoelectronic module 230, so as to obtain a reliable-insulated lighting module 200.

Since the package case 10 is closed, the package case 10 can cover the whole lighting module 200. With such an arrangement, the lighting module 200 can be prevented from contacting the housing 100, the packaging effect and reliability of the lighting module 200 can be improved, and the assembling steps and the assembling difficulty of the lamp can be reduced.

In order to improve the insulation performance of the lighting module 200 and prevent the housing from being charged, the package 10 may be an insulating package.
