Abstract

The utility model provides a reflection-type automobile head lamp which comprises a lamp housing and is characterized in that a light-distributing mirror is arranged at the front end of the lamp housing, a lower-beam LED lamp and a high-beam LED lamp are arranged inside the lamp housing, a radiating fin is connected with the bottom surfaces of the integrated circuit boards of the two LED lamps, reflecting mirrors are covered above the two LED lamps respectively, and the bottom surfaces of the reflecting mirrors are fixedly connected with the radiating fin. The reflection-type automobile head lamp has the advantages of low heat value of the light source, no radiation, reduction of the water fog production, long service life, high luminous efficiency of the light source, low energy consumption, small volume, good appearance and novel design.

Description

Reflective car headlamp

Technical field

The utility model relates to a kind of reflective car headlamp, belongs to the automobile lamp field.

Background technology

Mostly traditional car headlamp is incandescent lamp, Halogen lamp LED if adopting, gas-discharge lamp etc. are as light source, and after headlamp was lighted, temperature was higher in the lamp, very easily produces water smoke, not only influence each parts service life of lamp, and power consumption is also bigger, is unfavorable for energy-conservation.Adopt reflective headlamp, a speculum has occupied most of volume of lamp body, makes whole lamp configuration design be subjected to spatial constraints, and in addition, most of reflective headlamps need adopt light shield, and light shield is more loaded down with trivial details at design aspect.

Summary of the invention

The purpose of this utility model provides a kind of reflective car headlamp, and its energy energy savings increase the service life, and volume is little, helps inside and outside handsome in appearanceization design.

The technical solution of the utility model is: a kind of reflective car headlamp, has lamp housing, it is characterized in that: the lamp housing front end is equipped with lens, dipped beam LED lamp and distance light LED lamp are housed in the lamp housing, be connected with fin below the circuit circuit board of two LED lamps, the top of two LED lamps is covered with speculum respectively, and speculum bottom surface and fin are connected.

Led light source is high-power white light source, and behind the power connection, the light that the LED lamp sends is penetrated on speculum, sees through lens through the light of mirror reflects, can be met light type and brightness value that the GB4599 GB requires.Led light source belongs to cold light source, and caloric value is low, and radiationless, and operating temperature so reduced the water smoke phenomenon, has prolonged product service life about 60 ℃.Because led light source luminous efficiency height is not wasted any light, so than conventional lights energy-conservation at least 60%.Because led light source adopts the chip integrated technology, volume is little, reduces half with the required working space of the matching used speculum of led light source than prior art, for more space has been reserved in indoor design, make whole lamp appearance and modeling design freer, more be tending towards attractive in appearanceization and noveltyization.

Description of drawings

Fig. 1 is the structural representation of the reflective car headlamp of the utility model.

Fig. 2 is the A-A profile of Fig. 1.

Fig. 3 is the vertical view of Fig. 2.

1 lens among the figure; 2 low beam reflector; 3 high beam reflector; 4 dipped beam LED lamps; 5 fin; 6 distance light LED lamps; 7 lamp housings; 8 adjusting devices.

The specific embodiment

Reflective car headlamp has lamp housing 7, the front end of lamp housing is equipped with lens 1, dipped beam LED lamp 4 and distance light LED lamp 6 are housed in the lamp housing, two LED lamps are high power light sources, adopted the chip integrated technology, volume is little, be connected with fin 5 below the circuit circuit board of LED lamp, fin is connected by adjusting device 8 with lamp housing, fin adopts aluminum alloy materials, play heat radiation and supporting light sources effect, the instant and near light source is shared fin can reach the increase that has suppressed volume when dispelling the heat purpose.The top of LED lamp 4,6 is covered with low beam reflector 2 and high beam reflector 3, two speculum bottom surfaces respectively and is supported by fin and be connected.

During dipped beam work, light dipped beam LED lamp, the light that sends makes the light redistribution by the low beam reflector reflection ray, and the lens of process lamp body front end once forms "cut-off"line clearly.During distance light work, light distance light LED lamp, the light that sends sees through lens by the high beam reflector reflection ray and penetrates.Present technique has made full use of the led light source luminous efficiency, does not waste any light, can reach the requirement of GB4599 GB.

Claims

1. reflective car headlamp, has lamp housing, it is characterized in that: the lamp housing front end is equipped with lens, dipped beam LED lamp and distance light LED lamp are housed in the lamp housing, be connected with fin below the circuit circuit board of two LED lamps, the top of two LED lamps is covered with speculum respectively, and speculum bottom surface and fin are connected.
