Description
Technical field
The utility model relates to technical field of lighting fixtures, particularly a kind of automobile head light led light source.
Background technology
Automotive luminaire is occupied extremely important status in lighting field, its output accounts for about 10% of whole lighting source total output.Headlamp is throw light on when the night running light fixture of road ahead of automobile, is one of vitals that ensures the automotive safety operation.Nineteen twenty-five previously used car headlamp almost be the acetylene headlamp entirely.1913, the gas-filled incandescent lamp of band coiled filament came out, and because of it has higher brightness, had opened up wide prospect for the electric light source headlamp.Incandescent lamp utilizes red-hot tungsten filament to produce light radiation, makes the electric light awns that emits a brilliant light.In the mankind long-term practice and scientist's long term studies, halogen tungsten lamp was trial-produceed successfully in nineteen fifty-nine.It is to utilize the principle of halogen tungsten circulation to make, and it is longer than traditional incandescent headlamp life-span, brightness is bigger.What present automobile major part adopted all is this headlamp.People study and have invented xenon lamp after Halogen lamp LED, and the illumination brightness that it sends is 2 times of common Halogen lamp LED, and energy consumption only be its 2/3, can reach 10 times of common Halogen lamp LED service life.
Be filled with some halogen gases (normally iodine or bromine) in the glass shell of Halogen lamp LED, its operation principle is: when the filament adstante febre, tungsten atom is evaporated the back and moves to the glass tube walls direction, when near glass tube walls, the tungsten steam be cooled to about 800 ℃ and and halogen atom combine, formation tungsten halide (tungsten iodide or tungsten bromide).Tungsten halide continues to move to glass tube central authorities, get back to again on the oxidized filament, because tungsten halide is a kind of very unstable compounds, it can resolve into halogen vapour and tungsten again after meeting heat again, tungsten under deposition on the filament, remedies the part that is evaporated again like this.By this regeneration cycle process, not only obtained the service life of filament prolonging greatly (almost be incandescent lamp 4 times), simultaneously since filament can be operated under the higher temperature, thereby obtained higher brightness, higher colour temperature and the luminous efficiency of Geng Gao.The principle of luminosity of xenon lamp is: in the quartzy quartz glass tube of UV-cut uvioresistant, with the number of chemical gas filling, wherein major part is xenon and iodide etc., and then see through booster DC voltage moment of 12 volts on the car is pressurized to 23000 volts voltage, excite the xenon electronics in the quartz ampoule free through the high pressure amplitude of vibration, between two electrodes, produce light source, Here it is so-called gas discharge.And, can improve the light color temperature value by the white superpower arclight that xenon produced, and the sunshine in similar daytime, the required magnitude of current only is 3.5A during xenon lamp work, and brightness is three times of traditional based on halogen bulb, and service life is than long 10 times of traditional based on halogen bulb.
In the prior art shortcoming of automobile head light Halogen lamp LED be to use the life-span short, photoelectric transformation efficiency is low, and (electric energy only has 12%-18% can be converted into luminous energy, and remainder all scatters and disappears with the form of heat energy), and the shortcoming of automobile head light xenon lamp be cost an arm and a leg, optically focused is bad, penetration power deficiency in misty rain weather, can influence the safety that the driver drives, brightness is too high in addition also shakes easily to driver's eyes, has certain potential safety hazard.The glass lamp body of these glow discharge spot lamps is frangible, has increased the use and the maintenance cost of light source greatly, and simultaneously also because of social consumption increases, the Related product resources of production consume and pollute and increase, and in inadequate resource environment not good today, not environmental protection of the utmost point seems.
