Abstract
The utility model provides a projection-type automobile head lamp which comprises a lamp housing and a light-disturbing mirror arranged on the lamp housing. The projection-type automobile head lamp is characterized in that a convex lens is arranged at the inside front end of the lamp housing, a light shading plate is arrange at the middle part of the lamp housing, an LED lamp is arrange at the rear end of the lamp housing, a free-form-surface reflecting mirror is arranged oppositely to the upper part of the LED lamp, the integrated circuit board below the LED lamp is supported by a heat radiator, and the heat radiator and the lamp housing are connected through an adjusting device. The projection-type automobile head lamp makes full use of the luminous efficiency of the light source, saves the energy and prolongs the service life. Besides, the projection-type automobile head lamp has small volume and is reserved with larger inner space, thereby ensuring reasonable distribution inside the lamp, attractive appearance and novel design.
Description
Technical field
The utility model relates to a kind of projection 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.Adopt the headlamp of projection, a dipped beam group has occupied most of volume of lamp body, thereby whole lamp configuration design is very limited.After the tradition headlamp was lighted, temperature was higher in the lamp, very easily produces water smoke, influence other component life of outward appearance and lamp, and power consumption is also bigger, is unfavorable for energy-conservation.
Summary of the invention
The purpose of this utility model provides a kind of projection car headlamp, its energy energy savings, and the length that increases the service life, and volume is little, helps rational deployment, attractive in appearanceization of appearance and modeling and noveltyization design in the lamp.
The technical solution of the utility model is: a kind of projection car headlamp, has lamp housing, lens is housed on the lamp housing, it is characterized in that: the lamp housing Inner Front End is equipped with convex lens, shadow shield is equipped with at the middle part, and the LED lamp is equipped with in the rear end, and LED lamp top is relative with free-form surface mirror, surface-mounted integrated circuit below the LED lamp is supported by radiator, and radiator is connected by adjusting device with lamp housing.
Adopt technique scheme,, can make the interior layout of lamp more reasonable because the led light source volume is little; Free-form surface mirror has become semi-section by the original surfaces of revolution, has reduced certain volume, has reserved more space for indoor design, makes whole lamp appearance and modeling more be tending towards attractive in appearanceization and noveltyization; Adopt led light source can make that temperature is reduced to below 60 ℃ in the lamp, significantly reduce the possibility that water smoke produces, can prolong each parts service life of lamp; By the design of semi-section, when reducing volume, made full use of light source light-emitting efficiency, do not waste any light, can economize on electricity 70%; Adopt the free form surface luminous intensity distribution, make the light type more clear, luminous intensity distribution is more accurate, and outward appearance is more novel, and can reach the requirement of GB GB4599.
Description of drawings
Fig. 1 is the structural representation of the utility model projection car headlamp.
Fig. 2 is the A-A profile of Fig. 1.
1 free-form surface mirror, 2LED lamp, 3 radiators, 4 shadow shields, 5 convex lens, 6 lens, 7 lamp housings, 8 adjusting devices among the figure.
The specific embodiment
On the lamp housing 7 of projection car headlamp lens 6 is housed, lamp housing 7 Inner Front Ends are equipped with convex lens 5, shadow shield 4 is equipped with at the middle part, free-form surface mirror 1 is equipped with in the rear end, LED lamp 2 is housed in the lamp housing, the LED lamp is relative with free-form surface mirror, and the surface-mounted integrated circuit below the LED lamp is supported by radiator 3, and radiator and lamp housing are connected by adjusting device 8.LED lamp 2 is high-power white light source, and radiator adopts aluminum alloy materials, is fixed in the heat radiation of light source surface-mounted integrated circuit below, plays the supporting light sources effect simultaneously.Free-form surface mirror 1 adopts the semi-section structure, carries out luminous intensity distribution by the free form surface design, can reflect the light that the LED lamp sends with light to redistribute.Operation principle: behind the power connection, the light that the LED lamp sends blocks a part of light through shadow shield after reflecting by free-form surface mirror, and "cut-off"line penetrates through forming clearly behind the convex lens again.
