Abstract
The invention relates to a variable-color-temperature automobile lamp. Compared with a common halogen light source which is low in color temperature, low in lighting effect and limited in illumination distance on highways, the variable-color-temperature automobile lamp taking a xenon lamp as a light source is high in color temperature and can generate strong glare in the urban area. The variable-color-temperature automobile lamp comprises an aluminum substrate (1), light sources (2) are arranged on the aluminum substrate in a surface-mounted manner through reflow soldering, reflection cups (3) are assembled on the light sources, a Fresnel lens (4) is assembled right ahead the reflection cups, a color temperature regulating plate (5) is assembled at the focus position of the Fresnel lens, and a diaphragm (6) and a lens (7) are assembled right ahead the color temperature regulating plate according to imaging relation.
Description
technical field:
the present invention relates to a kind of automobile lamp of variable color-temperature.
background technology:
mostly existing car headlamp is to using that halogen bulb is as light source, more commonly H1 and H7 type, and the colour temperature of this light source is on the low side, belongs to the warm white in white light, and the light efficiency of this light fixture is very low, and on highway, irradiation distance is limited; Also have the automobile of some high configurations to adopt xenon lamp as light source, this light fixture colour temperature is higher, belongs to cold white light, produces very strong dazzle in urban district.
this car headlamp is usingd blue-ray LED as light source, by reflector, the blue light of wide-angle is become to quasi-parallel light, by Fresnel Lenses, blue light is being converged in a very little region, at the convergent point of blue light, place adjustable colour temperature plate, it is two states of the gentle warm colour temperature of cool colour that colour temperature plate is controlled changeable by frame for movement, after colour temperature plate, be placed to picture diaphragm and imaging lens, finally form the distance-light pattern of car headlamp.While travelling, be switched to the state of warm colour temperature in urban district, when guaranteeing illumination, reduce the dazzle of light fixture, when expressway, be switched to the state of cool colour temperature, make brightness reach high state.
summary of the invention:
the object of the present invention is to provide a kind of automobile lamp of variable color-temperature.
the object of the present invention is achieved like this:
a kind of automobile lamp of variable color-temperature, its composition comprises: aluminium base, light source by Reflow Soldering paster to aluminium base, reflector is assembled on described light source, Fresnel Lenses is assembled to the dead ahead of described reflector, colour temperature adjustable plate is assembled to the focus place of described Fresnel Lenses, diaphragm and camera lens are assembled to the dead ahead of described colour temperature adjustable plate according to imaging relations.
the automobile lamp of described variable color-temperature, described light source adopts blue-ray LED.
a kind of automobile lamp luminescent method of described variable color-temperature, car headlamp is usingd blue-ray LED as light source, by reflector, the blue light of wide-angle is become to quasi-parallel light, by Fresnel Lenses, blue light is being converged in a region, at the convergent point of blue light, place adjustable colour temperature plate, colour temperature plate is controlled and is switched to cool colour temperature or two states of warm colour temperature by frame for movement, is placed to picture diaphragm and imaging lens after colour temperature plate, forms the distance-light pattern of car headlamp; While travelling, be switched to the state of warm colour temperature in urban district, when guaranteeing illumination, reduce the dazzle of light fixture, when expressway, be switched to the state of cool colour temperature, make brightness reach high state.
beneficial effect:
1. the present invention coordinates the combination of blue-ray LED by colour temperature plate, and the combination that has replaced traditional halogen bulb and Xe lamp bulb to coordinate, is merged into a light fixture by original two light fixtures, has saved space, is of value to the design of headlamp moulding.
2. by blue light source, coordinate the light that is combined to form two colour temperatures of colour temperature plate, can greatly reduce the cost of product.
3. the present invention utilizes the LED can be compared with conventional lamp energy-conservation 50% as light source.
4. the present invention is simple in structure, and manufacturing process is also very easy, and development and production cost significantly reduces.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.
the specific embodiment:
embodiment 1:
a kind of automobile lamp of variable color-temperature, its composition comprises: aluminium base 1, light source 2 by Reflow Soldering paster to aluminium base, reflector 3 is assembled on described light source, Fresnel Lenses 4 is assembled to the dead ahead of described reflector, colour temperature adjustable plate 5 is assembled to the focus place of described Fresnel Lenses, diaphragm 6 and camera lens 7 are assembled to the dead ahead of described colour temperature adjustable plate according to imaging relations.
embodiment 2:
according to the automobile lamp of the variable color-temperature described in embodiment 1, described light source adopts blue-ray LED.
embodiment 3:
according to the automobile lamp of the variable color-temperature described in embodiment 1 or 2, car headlamp is usingd blue-ray LED as light source, by reflector, the blue light of wide-angle is become to quasi-parallel light, by Fresnel Lenses, blue light is being converged in a very little region, at the convergent point of blue light, place adjustable colour temperature plate, colour temperature plate is controlled and changeablely for two states of the gentle warm colour temperature of cool colour, is placed to picture diaphragm and imaging lens after colour temperature plate, the distance-light pattern of formation car headlamp by frame for movement.While travelling, be switched to the state of warm colour temperature in urban district, when guaranteeing illumination, reduce the dazzle of light fixture, when expressway, be switched to the state of cool colour temperature, make brightness reach high state.
Claims (3)
1. the automobile lamp of a variable color-temperature, its composition comprises: aluminium base, it is characterized in that: light source by Reflow Soldering paster to aluminium base, reflector is assembled on described light source, Fresnel Lenses is assembled to the dead ahead of described reflector, colour temperature adjustable plate is assembled to the focus place of described Fresnel Lenses, diaphragm and camera lens are assembled to the dead ahead of described colour temperature adjustable plate according to imaging relations.
