Background technology
In recent years, in Korea S, the energy that is used to throw light on reaches 18% of total power consumption, and along with the raising of people's living environment, this index is all increasing substantially every year.Now, according to the trend of globalization of earth environment protection, the energy efficiency by improving lighting field and by the energy-conservation electric energy that effectively uses, thus environmental pollution is reduced to minimum, people are very positive makes this effort.
Usually, for example, using the most general power equipment is incandescent lamp, fluorescent lamp or the like.
Owing to adopt the exemplary illumination system of this power equipment all to have mains switch, this mains switch only can be opened or close by user's manual operation, so, when the people leaves and switch when still being in opening, will waste electric energy, because this power equipment is still continuing illumination.And also there is another problem in traditional illuminator, that is, when wanting to open or close this power equipment at every turn, user's console switch of having to.
By current disclosed human body sensing illuminator, can address these problems greatly.
People are in frequent zone of using, for example, in inlet, Qianmen, corridor, stair, elevator entrance, warehouse or other places, this human body sensing illuminator is installed, when illuminance is lower than predetermined value and user and enters this zone, the automatic turns on power equipment of this system, and when illuminance be higher than predetermined value and should the zone in when not having the user, then this system closes this power equipment automatically.This human body sensing illuminator can provide illuminating effect, and the user need not be at every turn run switchs all, so just improved the convenience that uses, and the electric energy of avoiding waste, thereby can use electric energy effectively.
This human body sensing illuminator will be described below in further detail.This illuminator detects the infrared ray (6.5 μ m～15 μ m) that sends from human body, utilize contactless thermoelectric pickup to move at the remote human body that detects in the detection range, the infrared transmission that to send from human body by Fresnel lens is to the thermoelectric (al) type infrared sensor then, and then the output voltage with transducer is transferred to first amplifier circuit.This first amplifier circuit is used as band pass filter and amplifier, and has the amplification level of about 40dB.The small-signal that amplifies is transferred to second amplifier circuit through coupling capacitor for the first time, and the signal from the output of second amplifier circuit is transferred to window comparator then.Output square wave when output predetermined voltage and above signal, thus open or close this power equipment through timing circuit and triode ac switch ON/OFF circuit.
Here, triode ac switch ON/OFF circuit comprises the illumination sensor with CDS element, wherein this CDS element is made by the mixture that cadmium (Cd) and sulphur (S) mix mutually, when detecting predetermined amounts of light rays, its resistance can reduce fast, and its resistance can also be increased to hundreds of ohms (Ω).Therefore, this triode ac switch ON/OFF circuit can change according to illuminance and comes optionally opening and closing circuit, thereby provides lighting environment corresponding to illuminance.
As mentioned above, if above-mentioned any one element is omitted, the human body sensing illuminator that then has above-mentioned operation logic can not show its function, and can not use it at sealing area, for example the toilet.Just, when the user entered the toilet, this human body sensing illuminator detected user's turns on power equipment then.Afterwards, when not detecting the user and move, then this human body sensing illuminator is closed this power equipment after the section at the fixed time automatically, thereby it has increased sense of discomfort at one's leisure.
And, this human body sensing illuminator is that the user provides convenience owing to possessing automatic unlatching and closing automatically, but its shortcoming is, detect under the state that surpasses predetermined illuminance value in illumination sensor, when the user wants to open this power equipment so that when work, the user is can not be according to the wish of self manually opened easily or close this power equipment.And, this human body sensing illuminator also has some other shortcoming, promptly, when variation causes the illuminance excessive variation fast because of weather, frequent opening and closing meeting causes the life-span of this power equipment to shorten, and illumination sensor can frequently be made mistakes, and must replace whole human body sensing illuminator when illumination sensor loses its function.
In addition, as mentioned above, because the CDS element that is applied to this illumination sensor is made by the mixture of cadmium (Cd) and sulphur (S), and this mixture is harmful and pollute the environment, and must collect separately and processing so another problem of this human body sensing illuminator is this mixture.
CDS element as being applied to this illumination sensor can use photoelectric tube, phototransistor, photodiode or the like, and they can provide the effect that is similar to the CDS element.Yet they can not be applied to this human body sensing illuminator, because its volume is excessive, and because its too expensive meeting increases manufacturing cost, and can not realize compact human body sensing illuminator.And, because their principle is not that the lifting according to resistance value comes the switch related circuit as the CDS element, but produce electric current according to the radiation of light, the user must be especially careful when using this illuminator, because electric discharge phenomena can occur, like this, they just can not be applied to this human body sensing illuminator.
Therefore, people expect to obtain a kind of like this lighting device, it can omit illumination sensor, can be automatic and/or manually opened or close power equipment, thereby improvement ease of use, and, even manually opened or close under the situation of power equipment, it also can avoid waste of energy, except infrared sensor, also have multiple sensors can be applied to be used in this lighting device detect mobile human body, and it can provide a kind of simple structure and improved circuit design, thereby reduce error rate and manufacturing cost significantly.
