Problems solved by technology

[0005] The purpose of the present invention is to provide an LED outdoor light box to solve the problems of high heat generation, large space occupation and long response time in the above-mentioned background technology. Because it is not easy to maintain, it will generate a lot of unnecessary costs and consume a lot of energy. The lifespan is not long, the light color is messy, and the internal circuit will be damaged in a humid or vibrating environment, causing circuit hazards, and it cannot be moved arbitrarily.
