Description
Technical field
The utility model relates to LED lamp controller for opening and closing, especially a kind of based on human body infrared induction and with the LED lamp controller for opening and closing of exclusive disjunction.
Background technology
Inclusive-OR operation circuit, claims again OR-gate.In several conditions, as long as there is a condition to be met, certain event will occur, and this relation is called "or" logical relation.The circuit with "or" logical relation is called OR-gate.There are multiple inputs, only have an output.As long as have one when the level"1" in input, output be just level"1", only has in the time that all inputs are level "0" entirely, and exporting is just level "0".Logic OR is also referred to as logic add, and OR-gate expression formula is: F=A+B.
With door, claim again " with circuit ".Carry out the basic gate circuit of AND operation.Can there be several inputs, only have an output.In the time that all inputs are level"1" simultaneously, output is just level"1", otherwise is output as level "0".Logical expression: Y=AB, calls the turn at Hardware description language, and AND gate represents with " AND ".
BISS0001 is that a transducing signal with superior performance is processed integrated circuit.It is equipped with pyroelectric infrared sensor and a small amount of outward element and forms the pyroelectric infrared switch of passive type.It can open the devices such as all kinds of incandescent lamps, fluorescent lamp, buzzer, automatically-controlled door, electric fan, dryer and automatic hand washing sink automatically fast.
Light-emitting diode is referred to as LED.The diode of being made up of the compound of gallium (Ga) and arsenic (AS), phosphorus (P) can give off visible ray in the time of electronics and hole-recombination, thereby can be used for making light-emitting diode.In circuit and instrument as indicator light, or composition word or numeral show.Gallium arsenide phosphide diode glows, gallium phosphide diode green light, silicon carbide diode Yellow light-emitting low temperature.
LED is a kind of solid-state semiconductor device that can be visible ray by electric energy conversion, and it can directly be converted into light electricity.The heart of LED is a semi-conductive wafer, and one end of wafer is attached on a support, and one end is negative pole, and the other end connects the positive pole of power supply, makes whole wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is P type semiconductor, occupies an leading position in its hole, the inside, and the other end is N type semiconductor, is mainly electronics here.But when these two kinds of semiconductors couple together, between them, just form a P-N knot.In the time that electric current acts on this wafer by wire, electronics will be pushed to P district, and in P district, electronics, with hole-recombination, then will send energy with the form of photon, the luminous principle of LED lamp that Here it is.And the namely color of light of light wavelength is to be determined by the material that forms P-N knot.
Initial LED is as the instruction light source of instrument and meter, and various photochromic LED were widely applied in traffic lights and large-area displays screen afterwards, had produced good economic benefit and social benefit.Taking the red traffic lights of 12 inches as example, be to adopt the long-life originally in the U.S., 140 watts of incandescent lamps of low light efficiency are as light source, and it produces the white light of 2000 lumens.After Red lightscreening plate, light loss 90%, the ruddiness of only remaining 200 lumens.And in newly-designed lamp, Lumileds company has adopted 18 red LED light sources, including circuit loss, 14 watts of power consumptions, can produce same light efficiency altogether.Automobile signal light is also the key areas of LED light source application.
For general lighting, people more need white light source.The LED emitting white light for 1998 succeeds in developing.This LED is packaged together GaN chip and yttrium-aluminium-garnet (YAG) to make.GaN chip blue light-emitting (λ p=465nm, Wd=30nm), sends sodium yellow after the YAG fluorescent material containing Ce3+ that high temperature sintering is made is subject to this blue-light excited and penetrates, peak value 550nm.Blue-ray LED substrate is arranged in bowl-type reflection cavity, covers to be mixed with the thin resin layer of YAG, about 200-500nm.The blue light part that LED substrate sends is absorbed by fluorescent material, and the yellow light mix that another part blue light and fluorescent material send can obtain obtaining white light.For InGaN/YAG White LED, by changing the chemical composition of YAG fluorescent material and the thickness of adjusting phosphor powder layer, can obtain the white light of all kinds of colour temperature 3500-10000K.This method that obtains white light by blue-ray LED, simple structure, with low cost, technology maturity is high, therefore uses at most.
