Accompanying drawing explanation
Accompanying drawing 1 is the circuit working schematic diagram of a light-operated LED road lamp provided by the invention embodiment.
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 summary of the invention, 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 present invention, is further described correlation technique of the present invention below in conjunction with embodiment.
The technical parameter of components and parts and selection requirement thereof
RG is photo resistance, and the technical parameter of photo resistance is resistance in the dark >=1M Ω, bright resistance≤8K Ω;
VT1 is NPN type triode, and the model selected is 2SC9013 or 3DG12, requires β >=100;
