Technical field
The utility model relates to a kind of, especially a kind of explosion-proof type automatic flash energy-saving warning lamp control circuit.
Background technology
At present architectural engineering is more, as digs down water channel, laying-out etc., and the engineering construction location must be placed warning sign or warning lamp is installed.For present installation warning lamp on-site, because warning lamp light yellow always at night causes useful life short; Adopt the LED lamp as warning lamp although have at present, because the LED lamp needs stable electric current, present unsettled electric current is easy to cause the LED light decay quite serious etc., and the life-span shortens.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of explosion-proof type automatic flash energy-saving warning lamp control circuit is provided, and has stable electric current supply, adopts the LED lamp, by photoelectrical coupler control, adopts in the photoelectrical coupler from glimmering diode.
The utility model solves the technical scheme that its technical problem adopts: this explosion-proof type automatic flash energy-saving warning lamp control circuit, comprise power supply, power supply connects dropping equipment, rectifying device and filtering voltage regulation device successively, the filtering voltage regulation device is connected with the photoelectric eye that forms with photo-resistor, photoelectric eye connects photoelectrical coupler, wherein the photoelectrical coupler one group of LED lamp of connecting.Photoelectric eye is (when illumination is bright) energy autoshutdown warning lamp by day, and evening (when illumination is dark) is the opening warn lamp automatically, need not labor management.Whole circuit working is at contactless state, and LED lamp string is cold light source, can be used for the inflammable and explosive environment such as thread such as liquefied gas station.
Wherein photoelectrical coupler is by forming from flashing diode and light-receiving device.
Wherein photo-resistor comprises biasing resistor R
2With photo resistance RD, biasing resistor R
2And the base stage of the connection of the link between photo resistance RD NPN triode, the collector and emitter of NPN triode connects respectively photoelectrical coupler.
Wherein dropping equipment comprises decompression capacitor C parallel with one another
1With bleeder resistance R
