DETAILED DESCRIPTION

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Figure 1-Figure 3 The following is a schematic diagram of the overall structure of a protective LED smart street lamp of the utility model. Figure 1-Figure 3 A protective LED smart street lamp in this embodiment includes an LED lamp body 10 and a protective cover 20, wherein the LED lamp body 10 is installed on the inner side of the lower end of the protective cover 20; the protective cover 20 includes a U-shaped inner cover 201 which is embedded in the LED lamp body 10 except the bottom, and the U-shaped inner cover 201 is made of a high thermal conductive material, and the outer side of the U-shaped inner cover 201 is fixedly covered with a U-shaped outer cover 202, and a heat collecting and conducting cavity 203 is provided between the U-shaped outer cover 202 and the U-shaped inner cover 201, and the outer side wall of the U-shaped inner cover 201 has evenly distributed heat sinks 204, and one end of the heat collecting and conducting cavity 203 has an installation room, and a fan 205 is installed in the installation room, and one end of the bottom of the U-shaped outer cover 202 has an exhaust hole 202a corresponding to the air outlet end of the fan 205.

[0022] The inner side of the U-shaped outer cover 202 also has a heat-insulating coating 202b, and the U-shaped outer cover 202 is also coated with anti-rust paint. The U-shaped outer cover 202 provides external basic protection for the LED lamp body 10 and the entire device, and can provide shade and rain protection. At the same time, by coating the heat-insulating coating 202b on the inner wall of the outer cover, the additional heat brought to the lamp body by outdoor high temperature and sunlight can be effectively reduced, thereby achieving the effect of auxiliary heat dissipation.

[0023] Furthermore, a removable filter 206 is provided on the inner side of the exhaust hole 202a, which can prevent external flying insects and dust from entering the protective cover 20 and the heat collection and diversion cavity 203, while also protecting the fan 205. Furthermore, a temperature sensor can be provided inside the protective cover 20. As long as the temperature inside the diversion cavity or the temperature of the LED lamp body 10 reaches the set limit value, the control unit will immediately start the fan 205 and perform exhaust and heat dissipation, which is simple and effective.

[0024] It can be understood that a detachable inspection cover is provided on the top of the U-shaped outer cover 202, and after being disassembled, the fan 205 can be easily disassembled and assembled and the wiring can be performed.

[0025] A thermally conductive foam 207 is also attached to the inner side of the U-shaped inner cover 201 and is in contact with the outer side of the LED lamp body 10. The thermally conductive foam 207 also has evenly distributed heat dissipation holes 207a. In order to better dissipate the heat of the LED lamp body 10, the thermally conductive foam 207 can effectively increase the contact area between the LED lamp body 10 and the U-shaped inner cover 201. The excellent thermal conductivity of the thermally conductive foam 207 can quickly transfer the heat of the LED lamp body 10 to the U-shaped inner cover 201 and the heat sink 204, thereby improving the heat exchange efficiency. At the same time, the plurality of heat dissipation holes 207a can further reduce the heat accumulation of the thermally conductive foam 207, which is beneficial to the rapid dissipation of heat.

[0026] In this embodiment, during use, the U-shaped outer cover 202 can effectively reduce the additional heat brought to the lamp body by outdoor high temperature and sunlight with the cooperation of the thermal insulation coating 202b. At the same time, the LED lamp body 10 can quickly transfer heat to the U-shaped inner cover 201 and the heat sink 204 through the thermal conductive foam 207, so that the heat is accumulated in the heat collection and conduction cavity 203. At this time, the fan 205 can continuously suck the heat collection and conduction cavity 203, so that the internal heat is quickly taken away through the exhaust hole 202a. At the same time, the heat exchange efficiency of the heat sink 204 is also efficiently utilized, so that the heat of the LED lamp is difficult to accumulate. It has the characteristics of simple structure and good heat dissipation effect, provides good protection for the LED lamp, and is conducive to the long-term use of the lamp body.

[0027] Furthermore, mounting ears 208 matching the lamp pole are provided on both sides of one end of the U-shaped outer cover 202. The mounting ears 208 can be used to facilitate positioning and installation of the LED street lamp assembly, thereby improving its practicality.

[0028] Furthermore, the LED lamp body 10 and the protective cover 20 are connected by bolts. Here, a simple threaded connection can be used between the LED lamp body 10 and the protective cover 20 to facilitate installation and disassembly. Of course, other installation methods can also be used as long as they are convenient for installation and disassembly.

[0029] In summary, in the protective LED smart street lamp of the present embodiment, during use, the U-shaped outer cover 202 in cooperation with the thermal insulation coating 202b can effectively reduce the additional heat brought to the lamp body by outdoor high temperature and sunlight. At the same time, the LED lamp body 10 can quickly transfer heat to the U-shaped inner cover 201 and the heat sink 204 through the thermal conductive foam 207, so that the heat is accumulated in the heat collection and conduction cavity 203. At this time, the fan 205 can continuously suck the heat collection and conduction cavity 203, so that the internal heat is quickly taken away through the exhaust hole 202a. At the same time, the heat exchange efficiency of the heat sink 204 is also efficiently utilized, so that the heat of the LED lamp is difficult to accumulate.

[0030] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
