Description

Automatically control LED illuminating lamp

Technical field

The invention belongs to a kind of decorating lighting lamp, relate to a kind of high-power LED light source energy-saving lamp.

Background technology

LED is English light emitting diode(light-emitting diode) abbreviation; its basic structure is an electroluminescent semi-conducting material, is placed on a leaded shelf, then surrounding epoxy sealing; play the effect of protection internal core, so the anti-seismic performance of LED is good.LED(Light Emitting Diode), light-emitting diode, 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 comprised of two parts, and a part is P type semiconductor, in its hole, the inside, occupies an leading position, and the other end is N type semiconductor, here, is mainly electronics.But when these two kinds of semiconductors couple together, between them, just form a P-N knot.When 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 light wavelength color of light is namely to be determined by the material that forms P-N knot.Initial LED is as the indication 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.The red traffic lights of 12 inches of take are example, in the U.S., are to adopt the long-life originally, and 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, comprise circuit loss, power consumption is 14 watts altogether, can produce same light efficiency.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.Compare with the illumination effect of conventional light source, LED light source is low pressure microelectronic product, has successfully merged computer technology, the network communications technology, image processing techniques and embedded Control technology etc.The chip size using in tradition LED lamp is 0.25mmX0.25nm, and the size of illuminating LED generally all will be more than 1.0mmX1.0mm.Working platform type structure, inverted pyramid structure and the flip-chip design of the moulding of LED nude film can be improved its luminous efficiency, thereby send more light.The innovation of LED package design aspect comprises the substrate of high-conductivity metals piece, flip-chip design and naked dish casting type lead frame etc., adopt these methods can design the device of high power, low thermal resistance, and the illumination of these devices is larger than the illumination of traditional LED product.A typical high light flux LED device can produce several lumens to the luminous flux of tens of lumens, the design of upgrading can be in a device integrated more LED, or a plurality of devices are installed in single assembly, thereby are made the lumen number of output be equivalent to miniature incandescent lamps.For example, high-power 12 chip monochromatic LED devices can be exported the light energy of 200lm, and the power consuming is between 10～15W.The application of LED light source is very flexible, can make the various forms of compact products of point, line, surface; The control of LED is very convenient, as long as adjust electric current, just arbitrarily light modulation; Different photochromic combinations are changeful, utilize sequential control circuit, more can reach colourful dynamic change effect.LED has been widely used in various lighting apparatus, as battery powered photoflash lamp, miniature acoustic control lamp, safety flare, outdoor road and interior stairs illuminating lamp and building and mark continuous illumination lamp.The appearance of white light LEDs is substance one step that LED steps out to illumination functions from identification function.White light LEDs approaches daylight most, more can reflect preferably the true colors of irradiating object, so from technical standpoint, white light LEDs is undoubtedly the most advanced technology of LED.White light LEDs has started to enter some applications, and the products such as emergency light, flashlight, photoflash lamp are come out one after another, but because price is very expensive, so be difficult to popularize.The universal prerequisite of white light LEDs is prices, and prices must be after White LED forms certain market scale just likely, and both fusions finally depend on technological progress.ED wall lamp is again line style LED flood light etc., because its profile strip, also there is people that it is called to LED line lamp, mainly only to use for doing building decoration illumination, be used in addition sketching the contours the profile of heavy construction, traditional prior art is all with power supply of single configuration, and manufacture process bothers relatively, and use is the not easy-maintaining damaging.So make attendant's workload increase, the numerous prices of the similar LED light fixture of existing market kind are also relatively costly, the fail safe of using at product and all process imperfection in short problem the useful life of product, can not be fully and lifetime of LED match, lack a kind of deficiencies such as power supply of long service life.
