[0014] In some embodiments of the present application, a circumferential protrusion is provided at the junction of the light-transmitting portion and the circumferential edge area. The protrusion protrudes toward the lamp housing and is arranged opposite to the second accommodating groove. The sealing ring is provided with an annular slot. The protrusion is inserted into the annular slot and squeezes the sealing ring into the second accommodating groove.
[0015] In some embodiments of the present application, the sealing ring is further provided with a sealing peripheral edge, and when the protrusion squeezes the sealing ring into the second receiving groove, the sealing peripheral edge abuts against the side wall of the second receiving groove.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0042] According to the first aspect of the present application, Figures 1 to 5As shown, the first LED street lamp provided by the embodiment of the present application includes a lamp housing 10, a lens 20, a sealing ring 30 and an LED light source component 40. The lamp housing 10 forms a housing cavity 12 having a light outlet 11, the LED light source component 40 is arranged in the housing cavity 12, the lens 20 is installed on the lamp housing 10 and located at the light outlet 11, the LED light source component 40 emits light to the light outlet 11, that is, to the lens 20, and the light is transmitted through the lens 20 for illumination. The lens 20 has a light-transmitting portion 21 opposite to the LED light source component 40 and a circumferential edge area 22 surrounding the light-transmitting portion 21. When the sealing ring 30 and the lens 20 are installed on the lamp housing 10, the sealing ring 30 is arranged between the lamp housing 10 and the lens 20, and the sealing ring 30 forms a sealing arrangement between the lamp housing 10 and the circumferential edge area 22. Furthermore, the circumferential edge region 22 is provided with a first accommodating groove 221 along the circumferential direction, and the vertical distance between the bottom of the first accommodating groove 221 and the LED light source component 40 is greater than or equal to the vertical distance between the side surface of the light-transmitting portion 21 facing away from the LED light source component 40 and the LED light source component 40, and the sealing ring 30 has a white extension portion 31 along the circumferential direction, and the extension portion 31 is accommodated in the first accommodating groove 221.
[0043] When the LED street lamp provided by the present application is used, the LED light source 40 emits light, and the light is irradiated onto the lens 20, wherein most of the light is directly transmitted from the light-transmitting portion 21 for illumination, and a part of the light propagates horizontally in the lens 20 toward the circumferential edge region 22. Since the circumferential edge region 22 is provided with a circumferential first receiving groove 221, the vertical distance between the bottom of the first receiving groove 221 and the LED light source 40 is greater than or equal to the vertical distance between the side surface of the light-transmitting portion 21 away from the LED light source 40 and the LED light source 40, and the white extension portion 31 of the sealing ring 30 is accommodated in the first receiving groove 221, therefore, this part of the light propagating in the horizontal direction will be reflected by the extension portion 31 when irradiating the white extension portion 31, and this part of the light is reflected to the light-transmitting portion 21 and emits light for illumination. In this way, compared with the current LED street lamp, the LED street lamp of the present application can utilize the stray light propagating in the horizontal direction in the lens 20 for illumination, thereby reducing the light loss of the LED street lamp and improving the light utilization rate.
[0044] Furthermore, the end surface of the extension portion 31 is flush with the surface of the side of the light-transmitting portion 21 away from the LED light source 40, or the end surface of the extension portion 31 exceeds the surface of the side of the light-transmitting portion 21 away from the LED light source 40. In this way, the extension portion 31 can reflect almost all of the stray light propagating in the horizontal direction and emit light for illumination, further reducing the light loss of the LED street lamp and improving the light utilization rate.
[0045] like Figure 5As shown, an electrical cavity 15 is formed on the side of the lamp housing 10 away from the accommodating cavity 12. The electrical cavity 15 is used to install electrical components such as a driving module and a sensing module. In addition, the electrical cavity 15 is connected to the accommodating cavity 12 to lay wires to connect the driving module and the LED light source 40. After the driving module, the sensing module and other electrical components are installed in the electrical cavity 15, the electrical cavity 15 is sealed by closing the top cover 16. Figures 1 to 4 As shown, external water vapor is prevented from intruding into the electrical cavity 15. Further, as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a plurality of heat dissipation fins 17 are provided in an area of the lamp housing 10 opposite to the accommodating cavity 12 on one side thereof. The heat dissipation fins 17 can improve the heat dissipation efficiency of the heat generated when the LED light source 40 emits light.
[0046] like Figure 4 and Figure 6 As shown, the lamp housing 10 is provided with a second accommodating groove 13 along the circumferential direction. When the sealing ring 30 is installed, the portion of the sealing ring 30 away from the lens 20 is accommodated in the second accommodating groove 13. In this way, the second accommodating groove 13 can position the sealing ring 30, so that the sealing ring 30 will not move relative to the lamp housing 10 during the installation process, and the relative position between the sealing ring 30 and the lamp housing 10 is ensured to be stable, so that the sealing ring 30 can be quickly installed between the lamp housing 10 and the first accommodating groove 221 of the lens 20, thereby improving the accuracy and efficiency of assembling the sealing ring 30.
[0047] like Figure 2 and Figure 6 As shown, a circumferential protrusion 23 is provided at the junction of the light-transmitting portion 21 and the circumferential edge region 22. The protrusion 23 protrudes toward the lamp housing 10 and is arranged opposite to the second receiving groove 13. Figure 6As shown, the sealing ring 30 is provided with an annular slot 32, and the protrusion 23 is inserted into the annular slot 32 to squeeze the sealing ring 30 into the second receiving groove 13. When installing the sealing ring 30, the sealing ring 30 can be initially positioned and placed in the second receiving groove 13, and then the protrusion 23 is aligned with the annular slot 32, and then the lens 20 is pushed toward the lamp housing 10, so that the protrusion 23 pushes the sealing ring 30 to continue to squeeze into the second receiving groove 13 while being inserted into the annular slot 32. Alternatively, when installing the sealing ring 30, the annular slot 32 of the sealing ring 30 can be initially positioned and placed on the protrusion 23, and then the end of the sealing ring 30 away from the protrusion 23 is aligned with the second receiving groove 13, and then the lens 20 is pushed toward the lamp housing 10, so that the protrusion 23 pushes the sealing ring 30 to continue to squeeze into the second receiving groove 13 while being inserted into the annular slot 32. In this way, the sealing ring 30 is squeezed by the protrusion 23 and the groove wall of the second receiving groove 13, so that a sealing arrangement is formed between the lamp housing 10 and the circumferential edge area 22 to prevent water vapor from the external environment from invading the receiving cavity 12 and causing a short circuit to the LED light source component 40.
[0048] In order to make the sealing ring 30 easily squeeze into the second receiving groove 13 and ensure the sealing performance, Figure 6 As shown, the sealing ring 30 is further provided with a sealing peripheral edge 33, and the sealing peripheral edge 33 has elastic deformation performance. When the protrusion 23 squeezes the sealing ring 30 into the second receiving groove 13, the sealing peripheral edge 33 can be elastically deformed, thereby adapting to the groove width of the second receiving groove 13, so as to easily squeeze into the second receiving groove 13. In addition, when squeezing into the second receiving groove 13, the sealing peripheral edge 33 abuts against the side wall of the second receiving groove 13. That is, the sealing peripheral edge 33 is squeezed by the side wall of the second receiving groove 13 and the protrusion 23 and elastically deforms, so that a sealing arrangement is formed between the lamp housing 10 and the circumferential edge area 22.
[0049] Specifically, Figure 6 As shown, the sealing peripheral eaves 33 include a first peripheral eaves 331 and a second peripheral eaves 332, and the first peripheral eaves 331 and the second peripheral eaves 332 are symmetrically arranged relative to the annular slot 32. In this way, two seals can be formed between the protrusion 23 and the groove wall of the second receiving groove 13 by the first peripheral eaves 331 and the second peripheral eaves 332, thereby further ensuring the sealing between the lamp housing 10 and the circumferential edge area 22.
[0050] In the embodiment of the present application, the sealing ring 30 is an integrally molded component. In addition, the sealing ring 30 is injection molded using materials such as silicone, rubber, fluororubber, polytetrafluoroethylene, acrylic rubber, polyurethane, and chloroprene rubber, with high molding efficiency and good molding consistency. Among them, the material used for the sealing ring 30 can be a white base material, so that a white sealing ring product is molded to reflect stray light propagating in the horizontal direction; or, the sealing ring 30 needs to be plated after molding, so that the entire outer layer of the sealing ring 30 is white or a white layer is plated on the side of the extension portion 31 facing the light-transmitting portion 21, so as to reflect stray light propagating in the horizontal direction.
[0051] like Figure 2 , Figure 4 and Figure 6 As shown, the circumferential edge region 22 is provided with a plurality of hanging ears 24, which are spaced apart along the circumference, and the hanging ears 24 are located on a side of the first receiving groove 221 away from the light-transmitting portion 21. Figure 4 and Figure 6 As shown, the lamp housing 10 is provided with a plurality of hooking protrusions 14 corresponding to the plurality of hanging ears 24, and the hanging ears 24 are hooked on the hooking protrusions 14. When the lens 20 is pushed toward the lamp housing 10, the hanging ears 24 will pass over the hooking protrusions 14 and then hook on the hooking protrusions 14. Since the process of pushing the lens 20 toward the lamp housing 10 forms an extrusion compression on the sealing ring 30, after the external force pushing the lens 20 is withdrawn, the sealing ring 30 rebounds and generates a reaction force on the lens 20, so that the hanging ears 24 are more stably hooked on the hooking protrusions 14, and the sealing ring 30 is always in an extrusion deformation state, so as to ensure the sealing between the lamp housing 10 and the circumferential edge area 22.
[0052] In the embodiment of the present application, the lens 20 is an integrally formed component. Specifically, the lens 20 includes but is not limited to being made of materials such as acrylic material and transparent resin.
[0053] According to the second aspect of the present application, the present application embodiment also provides a second LED street lamp, such as Figure 7 and Figure 8 shown.
[0054] Specifically, Figure 8 As shown, the groove wall of the second receiving groove 13 away from the receiving cavity 12 is provided with an extension section 131, the extension section 131 extends into the first receiving groove 221, and the extension portion 31 is clamped between the groove wall of the first receiving groove 221 and the extension section 131. In this way, the extension section 131 can always limit the extension portion 31, thereby preventing the extension portion 31 from turning over, ensuring that the extension portion 31 always remains flat, and improving the reflection efficiency of the extension portion 31 to stray light.
[0055] In the LED street light of this embodiment, the extension section 131 is a continuous circle, so that the extension section 131 forms a continuous restriction on the extension part 31 along the circumferential direction, ensuring that the extension part 31 always remains flat, and improving the reflection efficiency of the extension part 31 to stray light. Alternatively, there are multiple extension sections 131, and the multiple extension sections 131 are spaced apart along the circumferential direction. The extension part 31 can also be restricted by the multiple extension sections 131 spaced apart along the circumferential direction, ensuring that the extension part 31 always remains flat, and improving the reflection efficiency of the extension part 31 to stray light.
[0056] The second LED street lamp provided in the present application is similar to the first LED street lamp in structure except for the above differences, and thus will not be described in detail here.
[0057] According to the third aspect of the present application, the application embodiment also provides a third LED street lamp, such as Fig. 9 and Fig.10 shown.
[0058] Specifically, in the LED street lamp, the sealing ring 30 is an integrated sealing ring with a circular cross section. Moreover, the sealing ring 30 is white as a whole, so as to effectively reflect stray light, so that stray light can also be used for light illumination, thereby improving light utilization. During assembly, a portion of the sealing ring 30 is embedded in the first receiving groove 221, and the other portion is embedded in the second receiving groove 13, so as to effectively reflect stray light. Moreover, when the hanging ear 24 is hooked on the hooking protrusion 14, under the extrusion force formed by the hooking, the groove wall of the first receiving groove 221 and the groove wall of the second receiving groove 13 squeeze the sealing ring 30, thereby forming a sealing arrangement between the lamp housing 10 and the circumferential edge area 22, preventing water vapor from the external environment from invading the receiving cavity 12 and causing a short circuit to the LED light source component 40.
[0059] Compared with the first LED street lamp, the third LED street lamp provided in the present application has the same structure except for the sealing ring 30 having a different structure, so it will not be described in detail here.
[0060] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
