Abstract
The invention discloses an automatic control system of indoor lamplight. The automatic control system comprises an LED (Light Emitting Diode) lamp, wherein a pyroelectric sensor is mounted indoors, and connected with a signal processing circuit by a lead; the signal processing circuit is connected with a single-chip microcomputer; a light ray detection sensor is connected with the single-chip microcomputer by a lead; the single-chip microcomputer is connected with a PWM (Pulse-Width Modulation) pulse circuit; the PWM pulse circuit is connected with an LED lamp brightness controller by a lead; and the LED lamp brightness controller is connected with the LED lamp by a lead. The automatic control system solves the problems that the existing generally used energy-saving lighting manners include voice-operated and contact switches and the like which have use limitation, an energy-saving purpose of a lighting lamp cannot be well realized, and very serious electric energy waste exists in lighting.
Description
Technical field
The invention belongs to light automatic control technology, particularly relate to a kind of indoor light automatic control system.
Background technology
Along with rapid development of economy, also increasing to the application of electric energy, waste of energy phenomenon is also on the rise simultaneously, and especially in indoor or some public places, illuminating lamp is through usually bright, people no matter whether is had to exist, therefore energy-saving illumination is more and more important, generally adopts now lighting energy saving mode to have acoustic control, touch switch etc., but has it to use limitation, well can not realize the energy-conservation object of illuminating lamp, cause throwing light on upper or there is very serious waste electric energy phenomenon.
Summary of the invention
The technical problem to be solved in the present invention: a kind of indoor light automatic control system is provided, lighting energy saving mode is generally adopted now to have acoustic control, touch switch etc. to solve, but there is it to use limitation, well can not realize the energy-conservation object of illuminating lamp, cause throwing light on upper or there is the problems such as very serious waste electric energy phenomenon.
Technical solution of the present invention:
A kind of indoor light automatic control system, it comprises LED, pyroelectric sensor is had at indoor location, pyroelectric sensor is connected with signal processing circuit wire, signal processing circuit is connected with single-chip microcomputer, and light detecting sensor is connected with single-chip microcomputer wire, and single-chip microcomputer is connected with pwm pulse circuit, pwm pulse circuit is connected with LED brightness controller wire, and LED brightness controller is connected with LED wire.
Light detecting sensor is photo resistance.
Beneficial effect of the present invention:
The present invention is on conventional LED basis, an integrated singlechip controller, by light intensity in sense switch sensing chamber with whether have people, by Single-chip Controlling pwm pulse signal circuit, the output of adjusting brightness of LED lamps controller, the brightness of automatic adjustment LED and switch, solve and generally adopt now lighting energy saving mode to have acoustic control, touch switch etc., but there is it to use limitation, well can not realize the energy-conservation object of illuminating lamp, cause throwing light on upper or there is the problems such as very serious waste electric energy phenomenon.
accompanying drawing illustrates:
Fig. 1 is present system composition schematic diagram.
embodiment:
A kind of indoor light automatic control system, it comprises LED, pyroelectric sensor is had at indoor location, the output signal of pyroelectric sensor is connected with the input wire of signal processing circuit, signal processing circuit is carried out filtering and is put into process, signal after filtering is put into outputs to the analog input end of single-chip microcomputer, light detecting sensor is connected with single-chip microcomputer wire, single-chip microcomputer is connected with pwm pulse circuit, pwm pulse circuit is connected with LED brightness controller wire, and LED brightness controller is connected with LED wire; Pyroelectric sensor is arranged on indoor porch, detects whether someone enters indoor by it, and whether light sensor detects indoor light enough, the need of turning on light, and determines the brightness of light.
Light detecting sensor is photo resistance.
