Background technology

LED is considered to the lighting source of 21 century.The LED luminescent device is cold light source, and light efficiency is high, and operating voltage is low, and energy consumption is low, and under same brightness, the LED energy consumption is 10% of incandescent lamp, 50% of fluorescent lamp.The LED life-span can reach 100,000 hours, is 10 times of fluorescent lamp, 100 times of incandescent lamp.With LED replace incandescent or fluorescent lamp, environment friendly and pollution-free.Safe and reliable, be convenient to safeguard.China's electric consumption on lighting accounts for 12% of gross generation.At present, the lighting of public building is controlled and is mostly adopted hand switch, the phenomenon of timely switch often occurs not having, thus the inconvenience that causes a large amount of energy wastes and use.In addition, unnecessary use, also can shorten useful life of light fixture.

At present, there is the phenomenon that efficiency is low, energy consumption is high in the most domestic intelligent building.With regard to the illuminator of intelligent building, the lamp in many places is often from morning to night to open, no matter whether these rooms or corridor have the people, also no matter How many people is arranged.Perhaps, when natural daylight illumination was fine, lamp can not be closed in time; Otherwise, when natural daylight illumination is difficult to meet people's demand, can not open in time light again.This lighting system, not only cause the waste of the energy, and can not meet the primary demand of people to illumination, caused very large impact also for simultaneously people's eyesight.Modern times throw light on except the basic living that meets the people, study requirement, the facility that will more focus on the saving of energy and use, and the requirement that meets ergonomic individual character aspect.Particularly in mansion, utilize the personnel ratios of computer operation to rise in recent years, quantity and the complexity of the work of different vision requirements increase greatly.So it is reasonable, economical, energy-conservation to accomplish, at first should adopt advanced and mature technology and product, as electric light source, light fixture, Lighting Control Assembly.Therefore, adapt to different individuals and need of work, in conjunction with automatically regulate intelligent illumination system with manual adjustments become essential.

Summary of the invention

Whether main purpose of the present utility model is to provide a kind of intelligent LED Lighting Control Assembly, can be according in operational environment, there being human and environment light filling brightness etc. to come switch and the brightness of self-control lighting.Adopt native system to have the raising power consumption efficiency, saves energy and the advantages such as supply of electric power pressure dual effect of having alleviated peak of power consumption.

In order to achieve the above object, the utility model adopts following technical scheme: a kind of intelligent LED Lighting Control Assembly comprises lighting detecting circuit, pyroelectric infrared sensor and signal processor, single-chip microcomputer and control circuit; Wherein, lighting detecting circuit gathers the strong and weak information of illumination and delivers to single-chip microcomputer, the pyroelectric infrared sensor Information Monitoring is delivered to single-chip microcomputer by signal processor, and single-chip microcomputer is crossed control circuit according to these information exchanges the LED lighting apparatus is carried out to switching manipulation and brightness regulation, thereby realizes illumination control.

Preferably, described pyroelectric infrared sensor is arranged with Fresnel Lenses outward.

Preferably, described Fresnel Lenses bottom is provided with hood for protecting rider, and the inwall of hood for protecting rider is provided with the internal layer that stops the infrared penetration layer.

Preferably, the internal layer of described hood for protecting rider is electroplated metal layer or spary metal powder enamelled coating.

Preferably, the optical sensor spare of described lighting detecting circuit employing is photodiode or triode.

Preferably, described single-chip microcomputer adopts common 8 single-chip microcomputers.

Operation principle of the present utility model is as follows: described lighting detecting circuit and pyroelectric infrared sensor gather whether illumination is strong and weak, indoor has the information such as people to deliver to single-chip microcomputer, single-chip microcomputer is analyzed these information and by control circuit, the LED lighting apparatus is carried out to switching manipulation and automatic brightness adjustment, thereby realize illumination control, reach energy-conservation purpose.

The beneficial effects of the utility model are: (1), can be with the very brightness of high accuracy from 0 to 100% adjusting light owing to being provided with single-chip microcomputer and control circuit; The ability that it has the judgement time period, if when the colour of sky grows dark fully, make LED send 100 ﹪ brightness, and all the other time periods are that the colour of sky is also brighter, make LED send 30-50% brightness, can further save electric energy like this, improves power consumption efficiency.(2) owing to being provided with infrared sensor and lighting detecting circuit, can make the LED illuminating lamp more intelligent, brightness detects to the lighting apparatus periphery by lighting detecting circuit, if brightness not single-chip microcomputer simultaneously detection signal processor whether collected the human body pyroelectricity transducing signal, according to having or not the human body pyroelectricity transducing signal, single-chip microcomputer is controlled at once lighting apparatus and is opened or closed.(3) in addition, due to after in Fresnel Lenses bottom, establishing an inwall hood for protecting rider that stops the infrared penetration layer being arranged, can reduce the investigative range of infrared sensor, make room lighting can, because investigative range excessive causes too much lighting of indoor illumination light fitting, not cause the waste of the energy.
