Technical field
The present invention relates to car lights, in particular it relates to a kind of condenser for dipped beam car light mould group.
Background technique
Currently, application comparative maturity of the LED light source in dipped beam car light mould group, the dipped beam car light mould group of LED light source
It is varied, but mould group minimizes, structure is simple, low cost and high-performance are development trends, and in these areas, there are also many
Development space, have features above car light mould group have good market potential.
Existing car light mould group, condenser generally only have single concentration structure, meet specific regulation (ratio to be formed
Such as ECE R123Class C, V, E regulation) dipped beam light shape, it is necessary to have the parts such as barn door, disadvantage of this is that
Not enough simplify in structure.
Existing car light mould group, in order to meet specific regulation, what is had will be arranged dozens of LED light source, by tens of
Part in a LED carries out bright, control of going out, and realizes that the brightness of specific region in dipped beam light shape changes, disadvantage of this is that,
The cost of mould group because LED light source large number of, higher cost, and mould group space is larger.
Therefore, this neighborhood technical issues that need to address are at present: the existing car light mould group containing condenser, integrated
Degree is lower, in order to form dead line, and reduces the brightness of some regions, and still with the realization of barn door part is increased, this makes
The structure of car light mould group is not simple enough, and volume is not small and exquisite enough；It is either controlled by the light on and off of a large amount of LED specific in dipped beam light shape
The brightness change in region, the cost that does so is inevitable higher, and there are many quantity due to the LED of needs and concentration structure quantity,
The volume of entire mould group is larger.
Summary of the invention
In order to overcome the problems referred above, it is an object of the invention to: a kind of condenser for dipped beam car light mould group is provided, it is described
A kind of technical solution of the condenser for dipped beam car light mould group is as follows:
