The automatic electrodeless dimming LED lamp employs the photoresistor, thereby enabling the variable resistor to be automatically adjustable and being more automatic and intelligent; and the LED lamp can enable the brightness thereof to be automatically adjusted according to external light intensity, thereby not only increasing comfort level but also saving electric energy.
Description
Technical field:
The utility model relates to a kind of LED lamp, the electrodeless change light of especially a kind of automation LED lamp.
Background technology:
Now on the illumination market; The general lighting lamp is replaced by various electricity-saving lamp; The led lamp also is wherein a kind of, and the led lamp is not only energy-conservation, durable, and light is soft; But the led lamp on the market can not be regulated light intensity according to the strong and weak realization of extraneous light mostly automatically continuously now, realizes the energy-conservation and automation of bigger meaning.This is the existing in prior technology weak point.
Summary of the invention:
The purpose of the utility model is exactly not enough to existing in prior technology, can regulate the strong and weak electrodeless change light of the automation LED lamp of light automatically and provide a kind of.
This programme is realized through following technical measures: the electrodeless change light of the utility model automation LED lamp; Comprise power supply, control circuit, charge-discharge circuit, thyristor gating circuit, led lamp pearl; Described power supply comprises live wire, zero line; Described control circuit is formed bridge rectifier by first diode, second diode, the 3rd diode, the 4th diode, and described charge-discharge circuit is made up of variable resistor, resistance a, electric capacity, and described variable resistor is a termination bridge rectifier after photo resistance, described photo resistance, resistance a, the capacitances in series; Other end ground connection; Described thyristor gating circuit is made up of voltage-stabiliser tube, resistance b, optocoupler, controllable silicon, and described resistance b and controllable silicon one end also connect and meet at power firestreak, and described resistance b and controllable silicon one end connect the 6th pin and the 4th pin of optocoupler respectively; First pin of described optocoupler is connected between resistance a and the electric capacity, and the 3rd pin of described optocoupler connects ground connection behind the voltage-stabiliser tube.Described led lamp pearl is connected between controllable silicon and the zero line.
Influence when photo resistance receives the ambient light line strength, when resistance changes, change the charging rate of electric capacity, thereby change the ON time of optocoupler, utilize the ON time of optocoupler, realize that thyristor operating angle changes, thereby realize that power is adjustable continuously automatically.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to adopted photo resistance, makes the variable resistor automatic and adjustable; Automation is with intelligent more, and the led lamp also can not only improve comfort level but also practiced thrift electric energy according to the strong and weak adjusting automatically of extraneous light brightness; This shows; The utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
