Abstract
The utility model relates to a headlamp for a motor vehicle, in particular to a laser headlamp. The laser headlamp for the motor vehicle comprises a transparent lamp shell, a laser source base is arranged in the lamp shell, the laser source base is provided with a laser source, the position above the laser source is provided with a reflecting mirror used for reflecting laser beams, the reflecting mirror is arranged on an arc-shaped yellow phosphorus filter lens base at the top of the lamp shell, the yellow phosphorus filter lens base is further provided with a yellow phosphorus filter lens used for allowing the laser beams to transmit, and a reflecting bowl used for reflecting the laser beams penetrating through the yellow phosphorus filter lens and collecting the laser beams to white light source rays is arranged below the yellow phosphorus filter lens. The laser headlamp is small in size, high in brightness, long in service life and high in fog-transmitting capacity and radiates little heat.
Description
Technical field
The utility model relates to a kind of motor vehicle headlight, is specifically related to a kind of laser headlight.
Background technology
In prior art, headlight is widely used on vehicle, and especially for sedan limousine, its requirement to headlight is higher.Automobile front lamp is from halogen regenerative-cycle headlamp to xenon headlight, then to even OLED headlight of full LED headlight, the light source of car light is constantly being evolved, and applies at present maximum still halogen regenerative-cycle headlamps.But halogen regenerative-cycle headlamp brightness is not high, the brightness of hernia headlight is high, but penetration capacity is poor, and its inferior position significant reaction of misty rain weather out.The bottleneck of its application of restriction because its heat radiation of LED lamp is bad always.
Summary of the invention
The purpose of this utility model provides a kind of motor vehicle laser headlight for the deficiencies in the prior art, and the large lamp assembly volume of this laser is less, heating is lower; Have benefited from the comparatively narrow hot spot of laser headlight itself, range of exposures or penetration power are all outstanding compared with LED, and especially at driving at night and misty rain weather, it is openr that therefore driver's seat also becomes, and can more early make danger judgement.
The technical scheme that the utility model provides is:
Motor vehicle laser headlight, comprise transparent lamp case, in described lamp housing, be provided with laser light source(-)holder, on described laser light source(-)holder, LASER Light Source is set, the top of corresponding LASER Light Source is provided with the speculum for reflect beams of laser light, speculum is arranged on the curved yellow phosphorus optical filtering microscope base in lamp housing top, on described yellow phosphorus optical filtering microscope base, be also provided with the yellow phosphorus optical filtering for transmission laser light beam, the below of described yellow phosphorus optical filtering is provided with for reflecting through the laser beam of yellow phosphorus optical filtering and makes it accumulate the reverberation bowl of white light source light.
Concrete, described laser light source(-)holder is three, and corresponding LASER Light Source is three, and corresponding speculum has three, and corresponding yellow phosphorus optical filtering has one.
Concrete, described LASER Light Source is laser diode.
The principle of laser headlight provided by the utility model is to allow the laser experience that LASER Light Source launches " penetrate, penetrate, two reflections, amount to " Four processes, first the blue laser that three beams is launched by laser diode first penetrates, then pass through the reflection of laser mirror, then focus on yellow phosphorus optical filtering and form white light, afterwards through reverberation bowl secondary reflection again, the white light beam that finally forms cover penetrates again.Laser headlight volume provided by the utility model is little, brightness is high, it is little to generate heat, long service life, mist transmitting performance are strong.
Brief description of the drawings
Fig. 1 is the structural representation that dissects of laser headlight described in the utility model.
1 lamp housing 2 laser light source(-)holder 3 LASER Light Source 4 speculum 5 yellow phosphorus optical filterings
6 yellow phosphorus optical filtering microscope base 7 reverberation bowls.
Detailed description of the invention
Be illustrated in figure 1 the cut away view of the motor vehicle laser headlight that the utility model provides, comprise transparent lamp case 1, in described lamp housing 1, be provided with three laser light source(-)holders 2, three lasing laser diode LASER Light Sources 3 of corresponding installation on described laser light source(-)holder 2, the top of corresponding laser diode light source 3 is provided with three speculums 4 for reflect beams of laser light, speculum 4 is separately positioned on the curved yellow phosphorus optical filtering microscope base 6 in lamp housing 1 top, on described yellow phosphorus optical filtering microscope base 6, be also provided with for 5 one of the yellow phosphorus optical filterings of transmission laser light beam, the below of described yellow phosphorus optical filtering 5 is provided with for reflecting through the laser beam of yellow phosphorus optical filtering 5 and makes 7 one of the reverberation bowls that it accumulates white light source light.
In this detailed description of the invention, laser diode 3 produces blue laser beam ejaculation, described blue laser beam is irradiated on speculum 4, reflexed on yellow phosphorus lens 5 by speculum 4, blue laser beam becomes white light after seeing through yellow phosphorus lens 5, then be irradiated on reverberation bowl 7, finally by the effect of reverberation bowl 7, white light reflection is arrived to front, reach radiation response.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement detailed description of the invention of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
