Description
Technical field
It the utility model is related to automobile lamp lighting technical field, and in particular to a kind of more curved surface dipped beams of LED lens group are anti-
Light microscopic.
Background technology
Low beam is the light fixture that automobile illuminates road ahead in night running, it luminous intensity distribution design be influence lighting quality and
The key factor of effect.Projection optical unit is applied on automobile low beam and increasingly popularized, because projection optical unit is not
Be only capable of to whole low beam bring it is high-grade feel and it has high light-gathering, good horizontal development width, it is also more attractive.
With the appearance of LED light source, LED light source as green light source with its is green, energy-conservation the advantages of transported extensively
For each lighting field；Dipped beam projection optical unit is also promoting the use of LED light source；But the projection of existing LED light source
Optical unit easy produced problem when carrying out luminous intensity distribution performance detection has：1st, dipped beam 75R brightness is inadequate；2nd, more than dead line
The brightness value of each point of IIIth area standard requirement is inadequate or uneven.
The content of the invention
For disadvantage mentioned above, the utility model purpose is to provide a kind of LED lens group more curved surface dipped beam reflective mirrors, LED
During light source luminescent, reflected respectively by three sections of curved surfaces on reflector, first paragraph curved surface ensures the bright of dipped beam 75R test points
Degree meets standard requirement, and second segment curved surface ensures that once each test point meets standard requirement to dead line, and the 3rd section of curved surface is to cut-off
III more than line area's each point carries out the supplement of light so that each test point meets standard requirement.
The technical scheme of the utility model technology is achieved in the following ways：A kind of more curved surface dipped beams of LED lens group
Reflective mirror, including reflective mirror body, described reflective mirror body are made up of installation region I, retroreflective regions and installation region II；Institute
The installation region I stated on installation region II with being equipped with locating dowel and mounting hole；Described retroreflective regions are symmetrical anti-by two
Light bowl connection composition, described reflective bowl bottom are provided with a notch, notch long 12.5-17.5mm, deep 1-2mm；Its feature exists
In：Described reflector is made up of three sections of surface joinings, three sections of curved surfaces be respectively first paragraph curved surface, second segment curved surface, the 3rd section
Curved surface；Second segment curved surface is located between first paragraph curved surface and the 3rd section of curved surface, and area is maximum；The upper edge arc length of first paragraph curved surface
The maximum distance of 12-13mm, upper edge and notch is 2.5-3.8mm；The upper edge arc length 45-55mm of second segment curved surface, thereon
The maximum distance at edge and reflector top surface is 10-15mm.
Described reflector has cover side at the top edge of the 3rd section of curved surface, is carried out a part of no light by cover side
Block, while part light is reflected to the 3rd section of curved surface, and IIIth more than dead line area is respectively clicked through by the 3rd section of camber reflection
The supplement of row light so that each test point meets standard requirement.
The utility model, simple in construction, production and processing is convenient, is reflected respectively by three sections of curved surfaces on reflector,
First paragraph curved surface ensures that the brightness of dipped beam 75R test points meets standard requirement, and second segment curved surface ensures that dead line once respectively detects
Point meets standard requirement, and the 3rd section of curved surface carries out the supplement of light to III more than dead line area's each point so that each test point meets
Standard requirement.
