Problems solved by technology
The pressure inside and outside the lamp cavity is equal, and the sealing and protection performance is poor. After a period of use, foreign matter such as dust can easily enter the cavity of the lamp and deposit inside the lamp, which reduces the lighting effect of the lamp, especially in rainy environments and places with a lot of dust Under the environment, it seriously affects the normal use of the lamps. It is necessary to frequently disassemble the lamps for maintenance and clean the inner cavity of the lamps, which is time-consuming and laborious, and the product cost is high.

Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. Such as figure 1 As shown, a lighting device provided by an embodiment of the present invention includes a light-emitting member (not shown in the figure) and a housing assembly 100. The housing assembly 100 includes an upper housing 110 and a lower housing 120. The upper housing 110 It is fixedly connected with the lower shell 120 and forms a sealed inner cavity 130, the light-emitting component is fixed in the sealed inner cavity 130, and the air pressure in the sealed inner cavity 130 is higher than that of the outside of the housing assembly 100 Through this design, the air pressure in the seale...

The invention is applicable to the field of the illumination device, and discloses an illumination device, which comprises a luminous component and a shell component, wherein the shell component comprises an upper shell and a lower shell, the upper and the lower shells are fixedly connected with each other, a closed inner cavity is formed between the upper and the lower shells, the luminous component is fixed inside the closed inner cavity, and the shell component is fixedly provided with an air nozzle part which is supplied for gas to flow into the closed inner cavity in a single direction, so the air pressure of the closed inner cavity is higher than that outside the shell component. The pressure of the closed inner cavity of the product is higher than the air pressure outside the product, so foreign matters outside the product are difficult to enter the closed inner cavity of the product, the sealing protective performance is good, the cleanliness of the inner cavity of the product is ensured, the product is free from being frequently disassembled to maintain, the time and labor are saved, and the application cost of the product is low.
Description
technical field [0001] The invention belongs to the field of lighting devices, in particular to a lighting device with good sealing and protection performance. Background technique [0002] At present, the main junction of the lamp includes two parts, the upper cover and the bottom case, which are sealed by a sealing ring. The pressure inside and outside the lamp cavity is equal, and the sealing and protection performance is poor. After a period of use, foreign matter such as dust can easily enter the cavity of the lamp and deposit inside the lamp, which reduces the lighting effect of the lamp, especially in rainy environments and places with a lot of dust In the environment, the normal use of the lamps is seriously affected. It is necessary to frequently disassemble the lamps for maintenance and clean the inner cavity of the lamps, which is time-consuming and laborious, and the product cost is high. Contents of the invention [0003] The object of the present invention i...
