Technical field
The invention belongs to public illumination field, more particularly to a kind of specular removal changed based on the magnetic padlock that pattern-recognition is developed
Street lamp.
Background technology
LED (Light Emitting Diode), light emitting diode is a kind of semiconductor devices of solid-state, and it can be straight
Connect and electricity is converted into light.LED heart is the chip of a semiconductor, and one end of chip is attached on a support, and one end is negative
Pole, the other end connects the positive pole of power supply, makes whole chip by epoxy encapsulation.Semiconductor wafer is made up of two parts,
A part is P-type semiconductor, and hole is occupied an leading position inside it, and the other end is N-type semiconductor, and electronics is mainly in this side.
But when both semiconductors are connected, one " P-N junction " is just formed between them.When electric current by wire acts on this
When individual chip, electronics will be pushed to P areas, and then electronics will be sent with hole-recombination in the form of photon in P areas
Energy, here it is principle luminous LED.I.e. and the color of the wavelength light of light, be to be determined by the material for forming P-N junction.
The practical and commercialization of high performance lED, makes lighting engineering face a new revolution.By multiple super brightness
The pixel lamp of red, blue, green three-color LED composition can not only send the various coloured light of wavelength continuously adjustabe, and can be sent out
Brightness turns into lighting source, incandescent lamp and LED solids for identical luminosity up to the white light of tens to one hundred candle light
For illuminating lamp, the power consumption of the latter only accounts for the former 10%-20%.
The white light LEDs produced now are made of largely by covering one layer of faint yellow fluorescent coating on blue-ray LED
, this yellow phosphor is a kind of dense typically by being blended in after the yag crystal for having mixed cerium is clayed into power
It is made in adhesive.When LED chip sends blue light, some blue light will be efficiently converted into a light very much by this crystal
The light of the wider predominantly yellow of spectrum, the feux rouges and green glow acceptor in naked eyes can be stimulated due to gold-tinted, the indigo plants of LED in itself are remixed
Light, makes it appear like white light.
LED modules are exactly that light emitting diode is encapsulated again together as necessarily regularly arranged, are added at some waterproofs
The product of reason composition is exactly LED modules, and LED modules are to apply wider product in LED product, in configuration aspects and electronics side
Face is there is also very big difference, and simple is exactly just into a LED module, again with a wiring board and shell equipped with LED
Miscellaneous makes LED life and luminous intensity more preferable plus some controls, constant-current source and related radiating treatment.
