When be fine day, sometimes rain and fog weather, different weather environment requires the colour temperature of headlamp light different.When fine day,
High color temperature illumination, such as Xenon headlamp are usually required, can make to seem brighter on the human eye sense organ of headlamp in this way, more extremely
It dazzles.When meeting rain and fog weather, it usually needs low color temperature illuminates, such as halogen headlamp, and such low color temperature has higher
Penetration capacity driver can be seen in rain and fog weather farther, becomes apparent from.No matter automobile lamp at this stage uses which
Kind light source is all that can not reach best illuminating effect under the driving situation of different weather using the white light of fixed colour temperature,
Therefore a kind of color temperature-tunable car headlamp is needed to allow driver that can cope with different weather variation.
Utility model content
To solve the problems, such as that current car headlamp can not adjust colour temperature in real time, the utility model provides a kind of adjustable color temperature
Vehicle laser headlamp.
To achieve the above object, the utility model uses following technical proposals：
A kind of color temperature-tunable vehicle laser headlamp, the laser headlamp include Laser output mouth, optical fiber, system chassis

After light beam homogenization, by optical fiber, which is carried out expanding integer by lens group in Laser output mouth and grating,
Headlamp light type is exported, while the PWM duty cycle of three primary colours RGB is adjusted to carry out the adjusting of colour temperature by controller；
Laser headlamp uses photodetachment structure.
Further, the laser light source of laser headlamp is the white light made of three primary colours RGB laser coupleds.
Further, the material of optical fiber is quartz, glass or plastics.
Further, the material of lens group is PC, PMMA or glass in Laser output mouth.
Further, anti-reflection film is plated on the surface of lens group in Laser output mouth.
Further, system chassis includes babinet, laser radiating module, laser diode module and drive module, laser

Cold heat-dissipating pipe connection, while forcing the gas of laser diode module surrounding quickly to flow by fan, and each fixed connection place
Use heat-conducting glue or heat-conducting silicone grease.
Further, drive module uses constant-current source ACC working methods.
Advantageous effect：
Drive vehicle in the case of different weather, by the utility model adjust colour temperature can get better penetration power and
Visual characteristic, due to sharing a set of lamp optical system, does not interfere with car light type, need not change when adjusting colour temperature output

White light made of conjunction.As shown in Fig. 2, system chassis 3 is connected by optical fiber 2 with Laser output mouth 1.The laser headlamp uses light
Electrically separated structure can reserve more spaces and carry out shape-designing to automobile.
In the present embodiment, after laser beam that the laser diode module in system chassis 3 is sent out homogenizes, by optical fiber 2,
The laser beam is carried out by lens group in Laser output mouth 1 and grating to expand integer, headlamp light type is exported, leads to simultaneously
It crosses controller 4 and adjusts the PWM duty cycle of three primary colours RGB to carry out the adjusting of colour temperature.
In the present embodiment, the material of optical fiber 2 is quartz, glass or plastics, flexible to a certain extent, can also be realized
" flexibility " of light is propagated.
In the present embodiment, system chassis 3 includes babinet, laser radiating module, laser diode module and drive module, is swashed
Light radiating module, laser diode module and drive module are bolted in babinet；Laser diode module and drive module are logical
