Abstract
The invention provides a light-control LED bulb lamp controlled by a thyristor. The LED bulb lamp is simple in circuit structure, the number of needed elements is small, and by means of a thyristor control circuit and the control function of a photoresistor, the LED bulb lamp can be automatically turned off in the day and automatically turned on at night.
Description
Technical field
The present invention relates to a kind of light-operated LED bulb lamp of thyristor control.
Background technology
LEDbulb lamp is high with its electricity-saving rate, the advantage that durability is strong is widely used in the illumination of residential building stairs port, and school, institutional settings office building stairs port, corridor illumination, if the lamp in these places LEDbulb lamp of light-controlled lamp, by reduce administrative staff labour intensity.
Summary of the invention
The light-operated LED bulb lamp of a kind of thyristor control of the present invention, utilizes light-operated and thyristor control function, allows LEDbulb lamp, and daytime turns off the light automatically; Night turns on light automatically.
A kind of light-operated LED bulb lamp of thyristor control, the profile of lamp continues to use the lamp body of common LED bulb lamp, only at lamp housing, a photo resistance is installed outward, thyristor and related control circuits are arranged on the inner chamber of lamp, utilize the change in resistance that photo resistance is different with night by day, control LEDbulb lamp and work automatically.
A light-operated LED bulb lamp for thyristor control, its circuit structure is made up of capacitance-resistance voltage reduction circuit, rectification circuit, thyristor control circuit, light-operated circuit and LED luminous plaque.
Accompanying drawing explanation
Fig. 1 is a kind of circuit theory diagrams of light-operated LED bulb lamp of thyristor control.
Embodiment
As shown in drawings, R1, C1 form capacitance-resistance voltage reduction circuit, utilize resistance-capacitance circuit to have constant-current characteristics, and choose C value and LEDbulb lamp can be made to have specified working current value, capacitance-resistance voltage reduction circuit carries next stage circuit after alternating current 220V is reduced some volts.The B of accompanying drawing is individual event full-wave rectifier, alternating current is become the direct current of pulsation.
As shown in drawings, IC1 is three terminal regulator, and its output connects filter capacitor C3, after voltage stabilizing and filtering, the direct current of pulsation is become more stable direct current supply light-operated circuit.
IC2 and peripheral circuit composition light-operated circuit, IC2 model is 555 time-base circuit chips, and 3 ends are output, connects the control end of thyristor, controls the conduction angle aperture of thyristor, thus controls the watt level of LEDbulb lamp; R5 is photo resistance, and its change in resistance controls the work of LEDbulb lamp.By day, light irradiates R5, and its resistance diminishes, and 2, the 6 pin current potentials of IC2 raise, then 3 end output low levels, and thyristor B does not obtain triggering level and ends, and LEDbulb lamp does not work; When The night screen has hung down, the resistance of R5 becomes large, 2, the 6 pin current potential step-downs of IC2, and 3 pin export high level, and thyristor B obtains trigger voltage and becomes conducting from cut-off, and LEDbulb lamp is bright.
As shown in drawings, LED is luminous plaque, and power and the connected mode of its LED chip are selected as required, and LED work is by thyristor control, and C2 is filter capacitor, the Rectified alternating current of SCR-output is become more stable direct current supply LED working power.
As shown in drawings, V is piezo-resistance, plays overvoltage protection effect, and C3 is filter capacitor, strobes, and R3, C4 are disturbing pulse absorbing circuits, can prevent the normal work because of of short duration light thunderous lighting light, lights of vehicle interfered circuit.
