Abstract
Provided is an LED ceiling-mounted lamp (bulb lamp) with the double power saving function. As the name suggests, double power saving is achieved as follows: on the premise that the LED lamp itself has the power saving function, a timer circuit is further utilized to make the lamp start a voltage/light regulation circuit in the lamp in the period after midnight to reduce about 30% luminance of the lamp, and therefore more electric energy is saved. According to the LED ceiling-mounted lamp (bulb lamp) with the double power saving function, the stepless voltage/light regulation circuit of a unidirectional SCR is adopted, the voltage/light is regulated by changing the length of conduction time in each period of the unidirectional SCR, and therefore the goal of double power saving is achieved.
Description
Technical field
The present invention relates to the LED ceiling light (bulb lamp) of a kind of pair of power saving.
Background technology
With it, energy-conservation advantage has entered resident's residential lighting field to LED ceiling light (bulb lamp), the LED ceiling light (bulb lamp) used as street lamp, due to the voltage rising of circuit after midnight, again in the time period after zero morning, the stair passage of residential building the few is walked about, in this time period, if continue to allow LED ceiling light (bulb lamp) keep vehement bright illumination, obviously there is no need.If allow LED ceiling light (bulb lamp) be operated under overvoltage situation after midnight, will make light fixture accelerate light decay, the danger even damaged.
Summary of the invention
The LED ceiling light (bulb lamp) of a kind of pair of power saving, adopt thyristor SCR stepless voltage regulation (light) circuit, and circuit reaches the purpose of pressure regulation (light) by changing the ON time length of thyristor SCR within each cycle.Be that LED ceiling light (bulb lamp) is while starting working, allow it be in vehement bright illumination state, then after continuous operation 5 hours, now, be again in the line voltage distribution superelevation, export a high level signal by timer circuit (3 pin of IC1), the effect relay J discharges, and its normally opened contact J disconnects resistance R 5 branch roads in relaxation oscillating circuit, makes the resistance in relaxation oscillating circuit become large, the conduction angle that causes thyristor SCR reduces, and reaches the purpose of pressure regulation (light).
The accompanying drawing explanation
Accompanying drawing is the circuit theory diagrams of the LED ceiling light (bulb lamp) of a kind of pair of power saving.
Embodiment
As shown in drawings, LD is LED ceiling light (bulb lamp), and the working condition of LD is being subject to the control of thyristor SCR, and the angle of flow aperture of thyristor SCR, controlled by the value of parallel resistance R4, R5 and capacitor C 1 in relaxation oscillating circuit.When R4, two resistance parallel connections of R5, by parallel circuits, to be known, its total resistance is little value.And little resistance can make the angle of flow of thyristor SCR increase, LED ceiling light (bulb lamp) is operated in brighter operating mode; When the normally opened contact J by relay disconnects R5, during only remaining R4, it is large that the resistance R in its relaxation oscillating circuit becomes.Large resistance value can make the current value of thyristor SCR diminish, as long as choose the value of R4, will allow thyristor SCR control LED ceiling light (bulb lamp) and reduce by 30% brightness from vehement bright state, thereby reach on the power saving basis that LED ceiling light (bulb lamp) has at itself, save electric energy by the brightness that reduces lamp again, reach the function of two power savings.
Reduce in the second half of the night the brightness of LED ceiling light (bulb lamp), a benefit in addition is, can allow LED ceiling light (bulb lamp) escape the harm of line over-voltage, makes LED ceiling light (bulb lamp) life-span longer.
As shown in drawings, IC1 is long timer circuit, and its model is CD4060.As long as adjust the value of R9, R10 and C3, just can realize the regularly overlength timing of 5 hours.R7, C2 are that electrifying self-resetting and the timer of timer starts timing circuit, at circuit, rigidly connect in energize, the 3 pin output low level signals of IC1, triode T conducting, the relay J adhesive, its normally opened contact J connects the R5 branch road, at this moment, relaxation oscillating circuit is opened greatly the thyristor SCR angle of flow, and the LD light fixture is operated in vehement bright state; When the timing of timer IC1 then, by the high level of 3 pin outputs of IC1, now, triode T cut-off, relay J tripping, its normally opened contact J off resistance R5 branch road, resistance list in the relaxation oscillator circuit is comprised of R4, increases the resistance value in original branch road.In the relaxation oscillator formed by R4, C2 and unipolar transistor B, because the R4 value has increased, to the angle of flow of thyristor SCR be reduced, thereby the illumination of LED ceiling light (bulb lamp) is reduced, make LED ceiling light (bulb lamp) under the prerequisite that itself there is power saving, save again the part electric energy by the illumination that reduces light fixture, realized the purpose of two power savings.
