Description
Technical field
The present invention relates to field of photoelectric technology, especially a kind of indicator light with threshold function.
Background technique
LED(Light Emitting Diode), light emitting diode is that one kind can convert electrical energy into consolidating for visible light
The semiconductor devices of state, it can directly be converted electricity to light.The heart of LED is the chip of a semiconductor, one end of chip
It is attached on a bracket, one end is cathode, and the other end connects the anode of power supply, is encapsulated entire chip by epoxy resin.
Semiconductor wafer consists of two parts, and a part is P-type semiconductor, and hole is occupied an leading position inside it, another
End is N-type semiconductor, is mainly electronics in this side.But when both semiconductors connect, just formation one between them
A P-N junction.When electric current acts on this chip by conducting wire, electronics will be pushed to the area P, and electronics is with sky in the area P
Cave is compound, and energy then will be issued in the form of photon, and here it is the principles that LED light shines.And the wavelength i.e. light of light
Color, be to be determined by the material of formation P-N junction.
LED can directly issue the instruction that the initial LED of red, yellow, blue, green, green, orange, purple, white light is used as instrument and meter
Light source, later various photochromic LED are widely applied in traffic lights and large-area displays screen, produce well
Economic benefit and social benefit.It was using long-life, low light view originally in the U.S. by taking 12 inches of red traffic light as an example
For 140 watts of incandescent lamps of efficiency as light source, it generates the white light of 2000 lumens.After Red lightscreening plate, light loss 90% is only surplus
The feux rouges of lower 200 lumens.And in newly-designed lamp, Lumileds company uses 18 red LED light sources, including circuit damages
Including mistake, 14 watts of power consumption altogether can produce same light efficiency.Automobile signal light is also the key areas of LED light source application.
For general illumination, light source of the people with greater need for white.The LED to emit white light is succeeded in developing within 1998.It is this
LED is that GaN chip and yttrium-aluminium-garnet (YAG) are packaged together and are made into.GaN chip blue light-emitting (λ p=465nm, Wd=
30nm), the YAG fluorescent powder containing Ce3+ made of high temperature sintering issues yellow light emission, peak value 550nLED lamp after by the excitation of this blue light
m.Blue-ray LED substrate is mounted in bowl-type reflection cavity, is covered to be mixed with the thin resin layer of YAG, about 200-500nm.LED substrate
The blue light components of sending are absorbed by fluorescent powder, and another part blue light is mixed with the yellow light that fluorescent powder issues, available white light.
For InGaN/YAG White LED, by changing the chemical composition of YAG fluorescent powder and adjusting the thickness of phosphor powder layer,
The assorted white light of colour temperature 3500-10000K can be obtained.This method that white light is obtained by blue-ray LED, simple structure, cost
It is cheap, technical maturity is high, therefore with most.
Currently, the overwhelming majority, due to the interference of electromagnetic field, will appear micro- at low voltage without threshold function in indicator light
Bright phenomenon.
