Accompanying drawing explanation
Accompanying drawing 1 is the circuit working schematic diagram of the light-operated LED road lamp embodiment that the utility model provides.
Embodiment
According to the light-operated LED road lamp circuit working schematic diagram shown in accompanying drawing 1 and accompanying drawing explanation, and according to annexation between components and parts in each several part circuit described in utility model content, and components and parts technical parameter described in execution mode requires and circuit production main points are carried out enforcement and can be realized the utility model, is further described correlation technique of the present utility model below in conjunction with embodiment.
The technical parameter of components and parts and selection requirement thereof
