Description

The LED automobile tail light
(1), technical field: the utility model relates to a kind of automobile tail light, particularly a kind of LED automobile tail light.
(2), background technology: energy problem has become the hot issue of mankind nowadays society; Energy savings and environmental issue have become one of major issue that various countries' city illumination construction need consider; There is at present 21% power supply to be used for illumination approximately; If can save the half the energy in the solid state lighting field, then can make huge contribution to the energy conservation of entire society.
LED (Light Emitting Diode; Light emitting diode) be a kind of solid-state semiconductor devices, it can directly be converted into luminous energy to electric energy, and the heart of LED is a semi-conductive chip body; Wafer is fixed on the support with colloid; One end is a negative pole, and the other end connects the positive pole of power supply, and entire wafer is got up by epoxy encapsulation.The semiconductor die lamellar body is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside; The other end is a N-type semiconductor, mainly is electronics here, when these two kinds of semiconductors couple together; Just formed a P-N knot between them, when electric current acted on this P-N knot through lead, electronics will be pushed to the P district; Electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in the P district.The light wavelength that LED sends is the color of light just, is to be determined by the material that P-N ties.
LED is directly had following advantage as lighting: the LED consumed energy is less with the incandescent lamp of light efficiency; LED does not have poisonous metal, can not produce pollution to environment; LED uses low-tension supply, and supply voltage is below 24V, and it is that a ratio uses the safer power supply of high voltage source, is specially adapted to the public place.
But also there are some defectives in the LED light fixture, and is lower like brightness ratio, will exceed doubly much though compare every watt luminous efficiency with ordinary lamp and lantern, still has been low a bit from whole lamp brightness; LED is a cold light source, when applying to the LED lamp on the automobile tail light, if brightness of illumination is not enough, will have influence on mental awareness, even may cause traffic accident.Thereby, when using LED, must solve the problem of LED luminance shortage as automobile tail light.
(3), utility model content: the technical problem that the utility model will solve is: to the prior art deficiency, provide a kind of brightness high, low in energy consumption LED automobile tail light.
The technical scheme of the utility model: a kind of LED automobile tail light; Contain LED luminescence chip body, reflector and housing, be provided with a plate shaped heat dissipation base in the housing, reflector is the reflector of falling the truncated cone shape; The bottom surface of the reflector of falling the truncated cone shape is fixed on the upper surface of heat dissipation base; LED luminescence chip body also is fixed on the upper surface of heat dissipation base, and LED luminescence chip body is positioned at the middle part of the reflector of falling truncated cone shape bottom surface, and the upper bottom surface of the reflector of falling the truncated cone shape is provided with plate shaped lampshade; The middle part of plate shaped lampshade is a cross optical transmission window, and the remainder of plate shaped lampshade is light tight.
The material of cross optical transmission window is a light transmission glass plate, and the material of all the other lightproof parts of plate shaped lampshade is the glass plate that is mixed with fluorescent material, and this is mixed with on the upper surface of glass plate of fluorescent material and scribbles light tight coating.
On the upper surface of heat dissipation base and be positioned at the reflector of falling the truncated cone shape and be provided with a hemispherical diffuser, the hemispherical diffuser covers on LED luminescence chip body wherein.
The material of heat dissipation base is gold, nickel, copper, chromium, silver, golden nickel alloy, gold copper, golden evanohm, electrum, monel, nichrome, bazar metal, chromiumcopper, Kufil or chromium silver alloy.Heat dissipation base can distribute the heat of LED luminescence chip body.
The material of the reflector of falling the truncated cone shape is a glass.The optical accuracy height of this glass, undeformed memory, heatproof.
The beneficial effect of the utility model: 1. the upper bottom surface of the reflector of falling the truncated cone shape of the utility model is provided with plate shaped lampshade; The middle part of plate shaped lampshade is a cross optical transmission window; The material of all the other lightproof parts of plate shaped lampshade is the glass plate that is mixed with fluorescent material; A part of light that LED luminescence chip body penetrates is mapped on the inwall of the reflector of falling the truncated cone shape after reflecting through the glass plate that is mixed with fluorescent material, and then after the inwall reflection of the reflector of falling the truncated cone shape, penetrates from the cross optical transmission window, like this; The light intensity that penetrates from the cross optical transmission window has obtained reinforcement; Can increase the light efficiency of 20%-40% effectively, solve the problem of LED automobile tail light luminance shortage, guarantee the safety traffic of automobile.Because the LED light fixture has characteristics such as low-power consumption, volume be little, thus can power saving, fuel-efficient, save space, reduce the waste of resource.In addition, the heat that LED luminescence chip body sends also can dispel the heat through the reflector of falling the truncated cone shape effectively, reduces junction temperature of chip, improves the performance of LED automobile tail light.
