Component.
To achieve the above object, the present invention uses following technical proposals：
A kind of baffle plate assembly of high reflectance for lens module, it includes light barrier, fixed baffle, barn door and U
Shape hood, fixed baffle and barn door are horizontally fixed on the top of U-shaped hood, bottom surface respectively；Light barrier is horizontally fixed on solid
Determine the upper surface of baffle；The front end face of light barrier is the curved surface of indent, is used to form the "cut-off"line of dipped beam；The material of light barrier
The mirror face stainless steel of high reflectance is selected, and its surface is carried out including the process aluminized, improves reflectivity, reflectivity energy
Reach 0.6-0.95.
Further, lens module forms "cut-off"line by light barrier, saves and pass through solenoid valve when dipped beam is lighted
Adjusting form "cut-off"line, this mode not only makes entire lens module compact-sized, while can also reduce product cost.
Further, U-shaped hood is fixed in the cavity of lens carrier；Lens carrier is circumferentially closed and front and back ends
For open-like shape；The front end of lens carrier is equipped with lens, and the rear end of lens carrier is connected with radiator.
Further, immediately ahead of lens module, the left side plane of light barrier is higher than the right plane.
Further, light barrier is fixed on the upper surface of fixed baffle by way of cold riveting；The thickness of light barrier is
0.1mm-0.4mm；The thickness of fixed baffle is 0.4mm-0.6mm.
Further, fixed baffle is fixed on the top surface of U-shaped hood by way of rivet hot；
Setting is provided with corresponding four rivetings there are four riveting column and two positioning columns on U-shaped hood on fixed baffle
Hole and two location holes, one of location hole are kidney slot；
Barn door is fixed on the bottom surface of U-shaped hood by four riveting columns, prevents light focusing, while can also keep maximum
Luminous flux.
Further, the front end of U-shaped hood is positioned by two positioning columns and lens carrier, and the side by locking screw
Formula is reinforced.
Advantageous effect：
1. the lens module of the present invention forms "cut-off"line when dipped beam part works by the effect of light barrier, and
It is not to drive baffle to form "cut-off"line by solenoid valve, not only reduces the production cost of the lens module in this way, also make
The lens module is compact-sized.
2. the present invention improves the reflectivity of light barrier by the techniques such as aluminize, the efficiency of LED is substantially increased.
