Abstract
Provided is a light emitting diode (LED) ceiling lamp with timing and automatic dimming functions. A circuit of the LED ceiling lamp is composed of a resistive and capacitive pressure relief circuit, a rectifier circuit, an inductance-capacitance (LC) composite filter circuit, a timer circuit and a lighting plate circuit. The timer circuit is provided with a change-over switch K so that timing change-over in winter and summer is facilitated. In summer, the change-over switch K is located at the turn-off position; and in winter, the change-over switch K is turned on. A relay is automatically tripped when the LED ceiling lamp works continuously for 4h, a capacitor C7 is opened through a normally-open contact, working current of the LED ceiling lamp is automatically reduced, and accordingly the LED ceiling lamp can perform automatic dimming.
Description
Technical field
The present invention relates to a kind of LED ceiling light of timing automatic light modulation.
Background technology
In the residential quarter dwelling house in the cities and towns, ceiling light is almost adopted in the illumination of stair mouth passage, is again the universal use along with the LED lamp at present, and the ceiling light of stair mouth is also brought into use the LED ceiling light.Just, LED ceiling light in the market, its function singleness, do not possess function with an automatic light meter, the LED ceiling light from light beginning just always vehement bright be switched off to the sky bright lamp till, the energy-saving efficiency that makes it the LED ceiling light fails to obtain abundant raising, is again because line voltage distribution major part after midnight all is overrate, causes the LED ceiling light to suffer damage easily.
Summary of the invention
The LED ceiling light of a kind of timing automatic light modulation of the present invention, timer circuit is introduced the control circuit of LED ceiling light, the relay function cut-out capacitance that utilizes the timer circuit output to connect, thereby reduce the operating current of LED ceiling light, reach the effect of light modulation, improved the energy-saving efficiency of LED ceiling light again.
A kind of LED ceiling light of timing automatic light modulation, its circuit structure is made up of resistance-capacitance depressurization circuit, rectification circuit, LC compound filter circuit, LED luminous plaque circuit and control circuit.
Description of drawings
Accompanying drawing is a kind of circuit theory diagrams of LED ceiling light of timing automatic light modulation.
Embodiment
As shown in drawings, R1, C1 and R7 form the resistance-capacitance depressurization circuit, and its capacitive part is made up of two loops.A loop is fixedly connected in the alternating current circuit of 220V by C1; 7 normally opened contact J controls by relay of the capacitor C in another loop are connected in the capacitor C 1.When setting-up time regularly count down to, the automatic tripping of normally opened contact J of relay, excision capacitor C 7, thus the operating current of minimizing LED ceiling light reaches function with an automatic light meter.
As shown in drawings, rectifier carries out rectification to the low-voltage AC of resistance-capacitance depressurization output, the direct current of output ripple.The composite filter of being made up of LC becomes more stably direct current to the direct current of pulsation and exports to the next stage circuit then.
As shown in drawings, IC2 and peripheral circuit are formed circuit with an automatic light meter, and IC2 is that model is the long timer of CD4046.The course of work of timer: the moment that obtains working power at the LED ceiling light, 12 pin presets of IC2 and counting beginning, the low level signal of the 3 pin output locking of IC12, at this moment, triode T becomes conducting by ending, and the LED ceiling light with specified operating current work; At the timing time of LED ceiling light then, 3 pin of IC2 become high level signal locking output by low level, and triode T is become by conducting and ends, the relay J tripping, its normally opened contact J cuts off capacitor C 7, thereby reduces the operating current of LED ceiling light, reaches the function of automatic Regulation.
As shown in drawings, the K on 10 pin of IC2 is the timing diverter switch, and when K was in off-state, the resistance on 10 pin was R4+R5, and the time regularly this moment is about 6 hours, is adapted to winter; When K was in closure state, the time regularly this moment was about 4 hours, is adapted to summer.
As shown in drawings, the luminous plaque of LED ceiling light adopt 6 strings many and circuit structures, accompanying drawing is 3 also, the several power according to the LED ceiling light of branch road in parallel determine.
As shown in drawings, V is piezo-resistance, plays the overvoltage protection effect in circuit; D1 is diode, when IC2 output high level, gives the 11 pin output block level signal of IC2 in circuit, keeps the output of 3 pin.
