Abstract
The utility model discloses a throw car light of two times of light -emitting rate gradings of formula short -distance beam head -light relates to motor vehicle head -light field, and the throw car light of two times of light -emitting rate gradings of formula short -distance beam head -light of the efficiency of light energy utilization improvement twice of formula head -light is throwed the tradition to concretely relates to ability. Including light source, the anti - light cup of ellipsoid surface, light screen, convergent lens, the anti - light cup of hemisphere face, bulb support frame and lens support, axis location installs the light source in the bulb support frame, and bulb support frame installs the front side anti - light cup, anti - light cup comprises anti - light cup of ellipsoid surface and the anti - light cup of hemisphere face, and the lens support is installed to anti - light cup front side, installs 15 degrees or 45 degrees light screens between anti - light cup and the lens support, and anti - light cup is together fixed with lens support butt joint installation, install convergent lens in the lens support. The utility model provides a tradition to throw formula short -distance beam headlamp light can the utilization ratio low, the extravagant energy and the problem that has the potential safety hazard.
Description
Technical field
The utility model is related to automotive headlight field, and in particular to it is a kind of can be by the luminous energy of traditional projection-type headlamp
Utilization rate improves the car light of two times of light emission rate luminous intensity distributions of projection-type lower beam headlamp of twice.
Background technology
The lighting quality of automotive headlight for traffic safety it is critical that.Headlamp is divided into far from irradiation distance
Light lamp and dipped headlights, from version reflective and projection-type is divided into.Because lower beam headlamp light field needs to have anti-dazzle cutting
Only line, so adopting projection-type structure mostly.Traditional projection-type structure by approximate spot light halogen bulb or hernia bulb, ellipse
Spherical reflecting cup, shadow shield and convergent lens are constituted.But automotive headlight light distribution structure only one of which in the market
Ellipsoid reflector, shadow shield blocks the luminous energy of half, so the utilization rate of luminous energy is low.In order to meet brightness demand, producer
Or user has to improve the power of bulb, do so not only wastes the energy, and there is also potential safety hazard.Because bulb
After power increase, electric current and heat are multiplied, and are easily caused that light fixture is aging and lamp holder fusing accelerates, and return generator, protect
Dangerous silk, storage battery bring excessive burden, many spontaneous combustion vehicles to be also due to what the measure of this raising bulb power was caused.
Utility model content
The utility model provides a kind of car light of two times of light emission rate luminous intensity distributions of projection-type lower beam headlamp, and the utility model is solved
The traditional projection-type lower beam headlamp efficiency of light energy utilization is low, wastes the energy and there is a problem of potential safety hazard.
To solve the above problems, the utility model is adopted the following technical scheme that：Two times of light emission rates of projection-type lower beam headlamp
The car light of luminous intensity distribution, including light source, ellipsoid reflector, shadow shield, convergent lens, hemisphere face reflector, bulb rack and lens
Support；Axial location is provided with light source in bulb rack, and bulb rack installed in front has reflector；Reflector is reflective by ellipsoid
Cup and hemisphere face reflector composition, the reflector first half is ellipsoid reflector, and reflector lower half is hemisphere face reflector；Light
There is lens carrier in source in hemispherical sphere center position, reflector installed in front, and 15 degree are provided between reflector and lens carrier
Or 45 degree of shadow shields, reflector is fixed together with lens carrier abutting joint；Convergent lens is installed in lens carrier.Hemisphere
Face reflector can also be replaced with aspherical reflector or the catadioptric lens of plated film.
The ellipsoid reflector lower half of traditional projection-type headlamp is adopted hemisphere face reflector by the utility model,
The hemispherical centre of sphere places spot light, and the light Jing reflectors reflection that spot light sends is returned along original optical path, is led in way is returned to
The ellipsoid reflector that the first half is irradiated to behind spot light position is crossed, it is achieved thereby that lower half luminous energy makes full use of.This reality
It is the twice of traditional projection-type headlamp light emission rate with new headlamp light emission rate, described spot light is before brightness is constant
Putting can reduce a half-power and use, and reach the purpose of energy-conserving and environment-protective, and spot light can also reduce Partial Power and use, and improve
Vehicle lamp brightness, so as to reduce potential safety hazard.

Specific embodiment
Below the utility model is described in detail with optimal embodiment.
As Figure 1-4, the car light of two times of light emission rate luminous intensity distributions of projection-type lower beam headlamp, including light source 1, ellipsoid is reflective
Cup 2, shadow shield 3, convergent lens 4, hemisphere face reflector 5, bulb rack 6 and lens carrier 7；Light source 1 is approximate spot light
Halogen tungsten bulb or hernia bulb, axial location is provided with light source 1 in bulb rack 6, and the installed in front of bulb rack 6 has reflective
Cup；Reflector is made up of ellipsoid reflector 2 and hemisphere face reflector 5, and the reflector first half is ellipsoid reflector 2, reflective
Cup lower half is hemisphere face reflector 5；Light source 1 is in hemispherical sphere center position；Reflector installed in front has lens carrier 7, instead
15 degree or 45 degree of shadow shields 3 are installed, the downside of shadow shield 3 there are two installing holes between light cup and lens carrier 7；Reflector with
The abutting joint of lens carrier 7 is fixed together；Convergent lens 4 is installed in lens carrier 7；The lateral surface of lens carrier 7 has three
Installing hole, lens carrier 7 has above an installing hole, and lens carrier 7 has two installing holes below；Peace above lens carrier 7
Dress hole is bolted on ellipsoid reflector 2, and two installing holes below lens carrier 7 are pacified with two of shadow shield 3
Dress hole is fixed on hemisphere face reflector 5.Hemisphere face reflector can also be with aspherical reflector or the catadioptric lens of plated film
Replace improving light emission rate.
Finally it should be noted that：Obviously, above-described embodiment is only intended to clearly illustrate the utility model example,
And not to the restriction of embodiment.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no need to be exhaustive to all of embodiment.And thus
Among the obvious change amplified out or variation are still in protection domain of the present utility model.
