AI Technical Summary
Existing outdoor stair lights are thick and have a non-tilted structure, resulting in a small solar panel area that receives little light. They also lack waterproofing and are prone to water ingress during heavy rain.
The lamp body adopts a laminated composite structure, integrating the solar panel, energy storage module and LED light source into a 15mm thick body and sealing it with PU glue. The bottom plate of the lamp body is designed with an inclined surface, combined with an asymmetrical inclined structure to maximize the light-receiving area of the solar panel, and a fully enclosed three-dimensional structure is used to improve waterproof performance.
The lamp body features an ultra-thin design, maximizing the power generation efficiency of the solar panels while also possessing excellent waterproof performance to ensure that water does not enter during rainy days.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1-3 As shown, this utility model discloses a solar staircase light, which includes: a lamp body 1, a solar panel 2, a lamp panel 3, a lithium battery 4, and a driver board 5. The lithium battery 4 is connected to the solar panel 2 and the driver board 5 respectively, and the driver board 5 is used to drive the lamp panel 3. The front side of the lamp body 1 is provided with a groove for installing the solar panel 2 and the lamp panel 3. The lamp panel 3 and the solar panel 2 are respectively installed in the groove and fixed by filling with PU glue 6. The bottom plate of the groove for installing the solar panel 2 of the lamp body 1 is inclined, so that the solar panel 2 has the largest light-receiving area after installation.
[0017] With the above structure, this utility model adopts a laminated composite structure, integrating the solar panel, energy storage module, LED light source, and its control system into a lamp body within 15mm, thus achieving an extremely thin and light structure.
