Abstract
The utility model discloses an LED automobile tail lamp comprising a lamp holder, a circuit board and a lamp housing, wherein a mounting groove is formed on the lamp holder, the circuit board is arranged in the mounting groove, and a plurality of LED lamps are arrayed on the circuit board and are connected via lead wires; and the lamp housing is covered on the lamp holder, refraction waves are formed on the inside wall surface of the lamp housing, arc-shaped flanges with the same number of the LED lamps are arranged on the top surface on the inner side of the lamp housing, and a plurality of annular pearl edges are formed on the peripheries of the arc-shaped flanges. By virtue of the refraction waves, the arc-shaped flanges and the annular pearl edges, light rays emitted from the LED lamp are collected via the refraction waves on the lamp housing and are then reflected to achieve the purpose of enhancing the intensity of light source; and meanwhile, by virtue of the annular pearl edges on the peripheries of the arc-shaped flanges on the inside wall of the lamp housing, cross refraction of the light rays is realized, so that the brightness and irradiation range of the automobile tail lamp is expanded, and the safety of driving is ensured.
Description
Technical field
The utility model relates to a kind of automobile tail light, especially relates to a kind of LED automobile tail light.
Background technology
LED (Light Emitting Diode), light emitting diode is a kind of solid-state semiconductor devices, it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer by lead, electronics will be pushed to the P district, and 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.And the light wavelength color of light just is by the material decision that forms the P-N knot.
LED is directly had the following advantages as lighting: 1, the LED consumed energy reduces 80% with the incandescent lamp of light efficiency; 2, LED does not have poisonous metal mercury, can not pollute environment; 3, LED uses low-tension supply, and supply voltage is between 6-24V, and is different and different according to product, so it is a safer power supply of ratio use high voltage source, is specially adapted to the public place.
But also there are some defectives in the LED lamp, and is lower as brightness ratio.The luminous efficiency of comparing every watt with ordinary lamp and lantern be to exceed doubly a lot, but from whole lamp brightness still relatively the end a bit.When especially using the LED lamp to 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.
The utility model content
The utility model has designed a kind of LED automobile tail light, and it has solved the problem of the luminance shortage that can exist when automobile tail light uses LED.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of LED automobile tail light comprises lamp socket, circuit board and lamp housing, is provided with mounting groove on described lamp socket, and described circuit board is positioned in the described mounting groove, is arranged with a plurality of LED lamps and is provided with lead to connect on described circuit board; Described lamp housing covers on described lamp socket, is provided with the refraction ripple in described lamp housing interior sidewall surface, is provided with several curved flanges such as corresponding with described a plurality of LED lamps at the inboard end face of described lamp housing, and described curved flanges periphery is provided with a plurality of annular ring lines.
Being arranged with a plurality of LED lamps on the described circuit board connects by parallel connection or series system.
Also be provided with the lead perforation on described lamp socket, described lead passes described lead perforation.
Described lamp socket both sides are provided with connecting hole.
Described lamp housing both sides also are provided with connecting hole.
This LED automobile tail light is compared with existing automobile tail light, has following beneficial effect:
(1) the utility model is owing to be provided with refraction ripple, curved flanges and annular ring line, and the light when the LED lamp penetrates converges light by refraction ripple on the lamp housing and reflects to realize increasing the purpose of the intensity of light source again; Simultaneously, utilize the annular ring line of the curved flanges periphery on the lamp housing madial wall again, make light produce the intersection refraction action again, thereby realize enlarging automobile tail light brightness and range of exposures, the final safety that guarantees driving.
(2) the utility model is owing to use led light source as the taillight light source, because LED etc. have the low-power consumption characteristics, thus can power saving, reduce the waste of resource.
