It is high.
Utility model content
Switching construction for the distance-light of the existing bis- optical lens mould groups of LED of solution is not compact, and the problem that manufacturing cost is high,
The utility model provides a kind of compact-sized, easy for installation, can reduce the high reflectance for lens module of manufacturing cost
Baffle plate assembly.
To achieve the above object, the utility model adopts the following technical solutions:
A kind of baffle plate assembly of the 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；Light barrier with a thickness of
0.1mm-0.4mm；Fixed baffle with a thickness of 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 being also able to maintain maximum
Luminous flux.
Further, the front end of U-shaped hood is positioned by two positioning columns and lens carrier, and passes through the side of lock screw
Formula is reinforced.
The utility model has the advantages that
1. the lens module of the utility model forms light and shade cut-off when dipped beam part works, through the effect of light barrier
Line, rather than drive baffle to form "cut-off"line by solenoid valve, the production cost of the lens module is not only reduced in this way,
Also make the lens module compact-sized.
2. the utility model improves the reflectivity of light barrier by the techniques such as aluminize, the efficiency of LED is substantially increased.
