Description

The energy-conservation long-life lamp of a kind of semiconductor

Affiliated technical field: novel new unit that relates in the modern lighting field of technical application under this, a kind of new semiconductor light-emitting-diode (LED) is as the energy-conservation long-life lamp of the solid-state illumination-semiconductor of light source.

Background technology:

At present, the lighting that people use on the market is divided into two big classes, i.e. incandescent lamp and fluorescent lamp (comprise compact fluorescent lamp, be called for short electricity-saving lamp)." modern light units and system engineering " Peng Miaoyan writes the People's Telecon Publishing House and publishes the 21st page in February, 2006: " incandescent lamp (for first generation lighting), existing more than 100 year history.Its principle of luminosity is: electric current flows through tungsten filament, produces a large amount of heat energy, makes the filament temperature rise reach that 2400～2900K becomes incandescent shape and luminous.Service life of incandescent lamp is short and light efficiency is not high, is 10～14Im/w, and 93%～94% of its general power all is converted into heat energy "." semiconductor light-emitting-diode and solid state lighting " history state light is write in Science Press's June in 2007 the 2nd page (transition of lighting engineering) and carried: " most of radiant light of incandescent lamp is an infrared ray; general incandescent lamp has only 7% electrical power to convert visible light to, and the general life-span of incandescent lamp is about 750～1000 hours." " Sichuan daily paper " on July 3rd, 2007 the 8th edition, the viewpoint reporter Li Yabiao of Xinhua, Jiang Guocheng report: (energy-saving illumination---the selection that must face), " incandescent lamp has only 6% electric energy to convert luminous energy to, and all the other electric energy convert heat energy to, waste very big ".And another light source " fluorescent lamp " low-pressure mercury fluorescent lamp is commonly referred to as fluorescent lamp, is second generation lighting." modern light units and system engineering " the 21st page: " fluorescent lamp (comprising electricity-saving lamp) belongs to glow discharge spot lamp.It is made up of the glass tube that lamp holder, hot cathode and inwall scribble fluorescent material.The operating circuit of fluorescent lamp is made up of fluorescent tube, ballast and glow starter (abbreviation starter).After the power switch closure, starter produces the glow discharge heating, bimetal leaf expanded by heating in the starter and bending, make the closing of contact, connect negative electrode and produce the glow discharge heating, the emission electronics, just in a flash at this, the ballast that is connected in the circuit produces higher self induction electromotive force, is added in lamp tube ends, makes gas and mercury vapour ionization in the glass tube and conducts electricity.The fluorescent material of the ultraviolet ray excited glass tube inwall that produces during mercury vapor discharge sends visible light.Fluorescent lamp and incandescent lamp contrast, its most outstanding shortcoming is.Colour rendering is relatively poor, and complex structure is installed inconvenience and ornamental relatively poor, starts slower.Starting difficult light efficiency when particularly temperature is low descends ".Power saving fluorescent lamp (being commonly called as electricity-saving lamp) consumes electric power than the incandescent lamp of making illuminator of tungsten filament and lacks, and only just can send and the as many light of incandescent lamp with 20% electricity." " semiconductor light-emitting-diode and solid state lighting " the 4th page: " just towards the compact development of tubule footpath, compact fluorescent lamp (that is: electricity-saving lamp) conversion efficiency can reach 28% to fluorescent lamp, and is higher four times than 100W incandescent lamp.This lamp is because of power saving, and the life-span is long, and can exchange with ordinary lamps, is generally adopted.The disadvantage of fluorescent lamp is that light output is relevant with temperature, at room temperature have maximum power output, increase or reduce temperature optical output power is reduced, other shortcomings are that color rendering is not high enough, be subjected to radio wavelength to influence big and noise is arranged, simultaneously because mercurous influential " environment.Lighting source then gradually develops into fluorescent lamp by incandescent lamp, and following hope then is LED (semiconductor light-emitting-diode).The colour temperature of incandescent lamp is at 2500～3000K, and the colour temperature of fluorescent lamp and white light LEDs all can reach 3000K～10000K.Incandescent lamp is thermoluminescence, and fluorescent lamp is gas luminescence and white light LEDs is chemiluminescence.The life-span of incandescent lamp has only 1000 hours, and fluorescent lamp can reach 10000 little time zones, and white light LEDs then can reach 100000 hours.The reaction time of incandescent lamp is fast, is about 100ms, and power consumption, and is frangible; And the fluorescent lamp reaction time is slower, and contains mercury vapour and can produce atmosphere pollution, and frangible; Then power saving of semiconductor light-emitting-diode (LED), the solid-state components characteristic is strong, vibration resistance, the reaction time is shorter." the Peoples Daily sixth version on July 26th, 2003; reporter: Fei Weiwei report (semiconductor lamp: also used not two a lifetime): ", replace traditional incandescent lamp and fluorescent lamp with solid-state illumination---the semiconductor lamp of semiconductor light-emitting-diode (LED) as new light sources.Under the same brightness, power consumption only is 1/10 of an incandescent lamp, and the life-span then is 100 times.Because semiconductor lamp has advantages such as energy-conservation, long-life, non-maintaining, easy to control, environmental protection, so the insider generally believes that substitute electron tube as semiconductor transistor, it also is trend of the times that semiconductor lamp substitutes conventional lights ".Along with people's growth in the living standard, environmental requirement is more and more higher, and fluorescent lamp can't resolve the stroboscopic problem, and but there is not this problem in semiconductor lamp, is " green illumination " on the real justice meaning.In " Xinmin Evening News " on June 23rd, 2007, report in the wind and cloud literary composition (room lighting how harmonious): " subject study shows that the high colour temperature (cold light source) of 5000K and 6500K is welcome by the student more, is fit to read, and the visual task of having relatively high expectations such as writes.In addition, than under the environment greater than 500Kx, the efficient of visual task is higher at illumination level, and visual experience is better, is more conducive to students ' reading and writes.The head of a family should select the learning desk lamp of high color temperature light source (cold light source) for use when selecting home-use luminous environment, but not the warm colour light source." cold light source said here is semiconductor lamp and energy-saving daylight lamp." China's Industry development report semiconductor lighting " national new material industry production is made every effort to promote into center, country's semiconductor lighting engineering developme and industry alliance compile, China Machine Press publishes the 3rd page the notion and the development course of semiconductor lighting (one) in January, 2006: " semiconductor lighting also claims solid-state illumination, is a kind of solid-state illumination of based semiconductor light emitting diode new type light source.The light emitting diode english abbreviation is LED.It is a kind of novel solid-state cold light source.Light emitting diode is born in the sixties in 20th century, has simple in structurely, and volume is little, and is in light weight, little power consumption, and advantage such as response speed is fast, and anti-seismic performance is good, and is easy to use, the application in electro-optical system is very general.Under spending equally as before, all there are remarkable advantages in the power consumption of LED and life-span than incandescent lamp and fluorescent lamp." thisly have light-focusing function and be particularly suitable for market, road, school, Landscape Lighting, family and use.
