Abstract
The utility model relates to an optical control timing device used for the automatic control of road lamps, neon lamps, etc., and comprises a power supply circuit, an optical control circuit, a timing circuit, a control box, etc. The optical control circuit is used to automatically control the switching on of a road lamp at night and the switching off of a road lamp at day break. The timing circuit can arbitrarily adjust the time of switching on within eight hours. The utility model has the advantages of simple structure and safety.
Description
The utility model relates to a kind of light-operated timing controller, is applicable to control automatically such as street lamp, neon light.
For the advertising lamp of neon light one class, require to turn on light at dusk, switch on and close automatically after several hours, all through the night light yellow.At present the light-operated power down switch of design does not have the effect that timing is regulated usually, and it is bright that put out night the daytime that can only realize street lamp, neon light, can't reach the requirement of light-operated timing.
The purpose of this utility model is to provide a kind of existing light-operated controller that time action is arranged again.
The purpose of this utility model realizes by the following technical solutions: according to the switch of intensity of illumination with light-operated circuit control street lamp, regulate the time of turning on light with timing circuit.It is made up of power circuit, light-operated circuit, timing circuit and controller box.Light-operated circuit is by relay K A
