Description
Technical field
The present invention relates to a kind of LED capacitance touch study adjusting light screen.
Background technology
LED(Light Emitting Diode), light emitting diode, is the semiconductor device of a kind of solid-state that can convert electrical energy into visible ray, and it directly can be converted into light electricity.The heart of LED is the wafer of a quasiconductor, 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, and inside it, occupy an leading position in hole, and the other end is N-type semiconductor, at the most mainly electronics.But the when that both quasiconductors coupling together, between them, it is formed for a P-N junction.When electric current acts on this wafer by wire when, electronics will be pushed to P district, and in P district, electronics is with hole-recombination, then will send energy with the form of photon, here it is the principle that LED is luminous.And the wavelength of light i.e. the color of light, it is to be determined by the material forming P-N junction.
Initially LED is used as the instruction light source of instrument and meter, and the most various photochromic LED are widely applied in traffic light and large-area displays screen, create good economic benefit and social benefit.As a example by the red traffic light of 12 inches, being to use the long-life originally in the U.S., 140 watts of electric filament lamp of low luminous efficacy are as light source, and it produces the white light of 2000 lumens.After Red lightscreening plate, light loss 90%, the HONGGUANG of the most remaining 200 lumens.And in newly-designed lamp, Lumileds company have employed 18 red LED light source, including circuit loss, power consumption 14 watts altogether, same light efficiency can be produced.Automobile signal light is also the key areas of LED light source application.
For general lighting, people are with greater need for the light source of white.The LED emitted white light for 1998 succeeds in developing.This LED is that GaN chip and yttrium-aluminium-garnet (YAG) are packaged together and are made.GaN chip blue light-emitting (λ p=465nm, Wd=30nm), the YAG fluorescent powder containing Ce3+ that high temperature sintering is made sends sodium yellow after being excited by this blue light and penetrates, peak value 550nLED lamp m.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 components that LED substrate sends is absorbed by fluorescent material, and the gold-tinted that another part blue light sends with fluorescent material mixes, and can obtain obtaining white light.For InGaN/YAG White LED, by changing chemical composition and the thickness of regulation phosphor powder layer of YAG fluorescent powder, it is possible to obtain the assorted white light of colour temperature 3500-10000K.This method obtaining white light by blue-ray LED, simple structure, with low cost, technology maturity is high, therefore uses at most.
