Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a small explosion-proof LED lighting module. Background Technology

[0002] In the lighting field, LED light source components and LED driver components are usually used together to achieve long-term stable lighting. When applied in locations with hazardous gases, ensuring the explosion-proof performance of both the LED light source components and LED driver components is crucial.

[0003] Currently, common explosion-proof methods still have some drawbacks: for LED light source components, they are generally placed in a closed explosion-proof cavity consisting of a transparent cover and a metal shell; for LED driver components, there are usually two methods: one is to place them in another explosion-proof metal shell, and the other is to add a shell to the LED driver component and use other explosion-proof methods, such as potting or sand filling. However, these current explosion-proof methods make the entire LED lighting module bulky. Multiple independent explosion-proof cavities or additional shells not only occupy more space but also increase material costs. At the same time, the complex structure makes the production process more complicated, further increasing manufacturing costs. Utility Model Content
