Description

Human body induction energy saving illumination light modulating device

Technical field

This design is by operational amplifier, controllable silicon, light-sensitive device, screw type lamp holder and screw type lamp socket, and discrete Resistor-Capacitor Unit is formed, realize general lighting lamp Automatic Control, it is the upgraded product of existing common corridor acoustic control lamp, can be widely used in occasions such as public corridor, passageway, corridor, family room's intraoral illumination, have the considerable energy saving characteristic, significantly prolonged the useful life of bulb, daily cost of use is very cheap.

Background technology

At present, public corridor lighting generally uses electricity-saving lamp or acoustic control lamp.Electricity-saving lamp has the characteristics of photochromic soft, saves energy, but the cost height, every price of certified products is all more than 20 yuan, at a low price be not real electricity-saving lamp, but make with substitution material, actual energy-saving effect is had a greatly reduced quality.Another big shortcoming of electricity-saving lamp is unsuitable frequent light on and off, can cause the life-span significantly to shorten like this.The acoustic control lamp that is to use common bulb of extensive use in the residential building building corridor, with respect to early stage " altar lamp ", the appearance of acoustic control lamp has been played certain effect for electrical energy saving, but also there is misoperation often, no matter whether people's process arranged, as long as there is certain sound of movement can cause that all electric light lights, thereby cause waste of electric energy, in addition, frequent misoperation also can make the life-span of bulb greatly reduce, and has increased electricity charge spending and manual maintenance cost.This design is surveyed by human body is moved, and the lighting and extinguish gradually and carry out of real realization the " people Lai Dengliang, turn off the light when you leave ", particularly bulb makes light change very soft, nature, cordiality, has more hommization.

Summary of the invention

The purpose of this utility model provides a kind of full automatic human body induction energy saving illumination light modulating device.At the many drawbacks of acoustic control lamp misoperation, whether the design has adopted induction coil to discern has human body to walk about nearby.At the easiest in a flash drawback of burning that the filament of common bulb is lighted in energising, the design has adopted the mode of lighting gradually and extinguishing gradually to control bulb, has prolonged the useful life of common bulb greatly.The course of work of this design is: can not move daytime at ordinary times, human body be arranged when annex moves when night, electric light will be lighted automatically, and is to light gradually by extinguishing state, as long as there is human body to move in investigative range, then electric light will continue to light.When human body away from after, through tens of seconds time-delay (delay time is predeterminable), electric light will extinguish gradually.Finish once action thus.

The design has adopted following measure to prolong the useful life of bulb and has saved electricity consumption:

Whether the mode that adopts induction coil to survey has the detection of people's process.On control circuit board, produce microwave oscillation signal, launch towards periphery by induction coil, under the situation of unmanned process, the microwave signal that induction coil is launched is stable not to be changed, through out-of-date, the microwave signal that induction coil is launched is through mobile human body reflected back induction coil as the people, and small variation will take place microwave signal on coil, after this variable signal was discerned by operational amplifier, the control controllable silicon was lighted bulb.Therefore

Adopt this induction coil identification mode control bulb, the possibility of misoperation is very little, and it is the sort of any acoustic control lamp can not occur

Big sound all can cause the phenomenon that bulb is lighted, and has both prolonged the useful life of bulb greatly, has saved valuable electric energy again.

The damage of common bulb is being lighted in a flash often, and filament rises to 3000 ℃ incandescent state from room temperature moment, repeatedly back and forth impacts, thereby causes filament to damage.The design adopts the mode of gradual change, has avoided the filament temperature sudden change, thereby has effectively prolonged the useful life of bulb.And the acoustic control lamp operational environment was in dark state in the past, lighting suddenly and extinguishing of bulb has tangible sense of discomfort to human eye, adopt the mode of gradual change also to make light become very soft, eliminated that bulb is bright, the sudden change of going out is to the stimulation of human eye, demonstrates fully humanized design concept.Lighting and extinguishing of bulb controlled the silicon controlled angle of flow by operational amplifier and realized, when induction coil has recognized the people through out-of-date, operational amplifier is increased to 180 degree with the silicon controlled angle of flow gradually from 0 degree, bulb is lighted gradually, after leaving investigative range, human body delays time again a bit of time, operational amplifier drops to 0 degree with the silicon controlled angle of flow gradually from 180 degree, and bulb is extinguished gradually.
