Abstract
The utility model relates to a light control light fixture, the output of a power supply circuit of the utility model is led out from both ends of a bridge rectifier, both ends of the bridge rectifier are respectively connected with both ends of a branch circuit and both ends of a power supply of a trigger integrated block, and a photoresistor is connected in series with a potentiometer to form the branch circuit; the input end of the trigger integrated block is connected with the connection point of the series branch circuit, the input adjusting end of the trigger integrated block is connected with the sliding end of the potentiometer, and a relay and a reverse diode are connected in parallel between the output end of the trigger integrated block and the negative power supply end of the trigger integrated block; another potentiometer is connected between the positive and the negative power supply ends of the trigger integrated block, the sliding end of the potentiometer is connected with the output adjusting end of the trigger integrated block, and the normally open contact of the relay is connected in series between a light tube of the light fixture or a light filament of a light bulb and an AC power supply return circuit.
Description
The utility model relates to a kind of light fixture, particularly a kind of light-operated light fixture.
Existing various light fixture does not all have light-operated function, can not illuminating or closing and go out according to ambient light illumination automatic control lamp tool, people particularly the student sometimes in when read-write, tend to occur in time do not turn on light when day dark or day brighter forget again turn off the light, the former can influence people's eyesight, and the latter then can cause meaningless waste.In addition, the ambient light illumination of people sensation is inaccurate, and very big deviation is arranged, and often sensation does not have brightlyer when need not to turn on light, and in fact illuminance is not enough, and this also is a reason that causes people's eyesight to descend.
The purpose of this utility model is exactly in order to address the above problem, provide a kind of can be according to the light-operated lamp that has light-operated switch of the light on and off of ambient light illumination automatic control lamp tool.
Technical solution of the present utility model:
A kind of light-operated lamp that has light-operated switch, it includes by power transformer B, bridge rectifier D, power circuit and light fixture that filter capacitor C forms, the output that it is characterized in that power circuit is drawn from the two ends of bridge rectifier D, connect photo resistance RG is connected in series the two ends of branch road and triggers ic chip with potentiometer W1 both ends of power respectively, input 6 pin of IC are connected in series RG in the branch road with above-mentioned, the tie point of W1 links to each other, the input adjustment of IC holds 2 pin to connect the sliding end of potentiometer W1, between output 3 pin of IC and its negative power end 1 pin and be connected to relay J and backward diode D1, between the positive-negative power end of IC, be connected to potentiometer W2, the sliding end of W2 holds 5 pin to link to each other with the output adjustment of IC, and the normally opened contact Ja of relay J is serially connected between the filament and ac power supply circuit of the fluorescent tube of light fixture or bulb L.
The utility model can be according to the light on and off of ambient light illumination automatic control lamp tool; light fixture is opened automatically when ambient light illumination is lower than 250LX; when greater than 1000LX; light fixture extinguishes automatically; its control precision height, accuracy is good, and can adjust at any time according to actual needs; sight protectio to people is very helpful, and also can reduce some unnecessary power wastages simultaneously.The utility model can be widely used in desk lamp, reading lighting and place to operate schools etc., and effect is very good.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is an electric theory structure schematic diagram of the present utility model.
As Fig. 1, the utility model includes by power transformer B, bridge rectifier D, power circuit and light fixture that filter capacitor C forms, characteristics of the present utility model are, the output of power circuit is drawn from the two ends of bridge rectifier D, connect photo resistance RG is connected in series the two ends of branch road and triggers ic chip (model can be 555) with potentiometer W1 both ends of power respectively, input 6 pin of IC are connected in series RG in the branch road with above-mentioned, the tie point of W1 links to each other, the input adjustment of IC holds 2 pin to connect the sliding end of potentiometer W1, between output 3 pin of IC and its negative power end 1 pin and be connected to relay J and backward diode D1, between the positive-negative power end of IC, be connected to potentiometer W2, the sliding end of W2 holds 5 pin to link to each other with the output adjustment of IC, and the normally opened contact Ja of relay J is serially connected between the filament and ac power supply circuit of the fluorescent tube of light fixture or bulb L.
The utility model is connected to the serial connection branch road of resistance R and light-emitting diode D2 between another output 7 pin that trigger ic chip and its positive power source terminal, it is used to refer to operating state of the present utility model.
The course of work of the present utility model is, when ambient light illumination is low, as be lower than 250LX, then the internal resistance of photo resistance RG changes, its triggering signal triggers ic chip work, and then the output signal of IC output makes the line bag of relay J get electric work, its normally opened contact Ja closure, then the fluorescent tube of light fixture or bulb L light automatically, guarantee indoor enough illuminance that has.
Otherwise, when the fluorescent tube of light fixture or bulb L have thrown light on, if ambient light illumination is enough, as greater than 1000LX, then the internal resistance of photo resistance RG also changes, and by triggering ic chip relay J is discharged, and then normally opened contact Ja is opened by normally closed often reverting to, automatically cut off lamp power, conservation of power.
The resistance of regulator potentiometer W1, W2 can realize the adjustment of the utility model to the illuminance control range, to satisfy the needs of various occasions.
