It penetrates on bowl, reaches sidelight lens by the reflection of reverberation bowl, reflected away across sidelight lens；Effectively prevent the prior art
Using projection-type scheme, baffle is needed to realize "cut-off"line function, and to installing, positioning requirements are higher, when baffle position occurs
Offset, actual dipped beam light type will necessarily shift, and then cause the consistency of whole lamp production poor, influence safe driving and
The problem of driver experiences, no setting is required baffle reduce the deviation in components installation process, save installation when
Between, improve efficiency.
Scheme as a preference of the above scheme, sidelight lens are non-spherical lens.Non-spherical lens has more preferably
Radius of curvature can maintain good lens error correction, to obtain required performance.
Scheme as a preference of the above scheme is covered with the decorative pattern of protrusion on reverberation bowl.It is covered on reverberation bowl convex
Decorative pattern out reflects away light as much as possible by reverberation bowl.
Scheme as a preference of the above scheme, reflection bowl surface are coated with aluminium film.Reflection bowl surface is coated with aluminium film, makes anti-
Bowl is penetrated preferably to reflect.
Scheme as a preference of the above scheme, PCB luminescence component include the area source fixed on a heat sink and set
The power supply module set in radiator and be electrically connected with area source.Area source is mainly used for shining, and power supply module is mainly used for face
Light source power supply.
Scheme as a preference of the above scheme, area source paste radiator by the heat-conducting silicone grease with stickiness
On.Heat-conducting silicone grease can conduct heat and area source can be made fixed on a heat sink.
Scheme as a preference of the above scheme, sidelight lens are convex lens.Sidelight lens are convex lens, enable light
It is reflected away through sidelight lens.
The beneficial effects of the utility model are:
1. the utility model effectively prevents the prior art using projection-type scheme, baffle is needed to realize "cut-off"line
Function, higher to installation positioning requirements, when baffle position shifts, actual dipped beam light type will necessarily shift, in turn
Cause the consistency of whole lamp production poor, influence safe driving and the problem of driver experiences, no setting is required baffle reduces zero
Deviation in component installation process, improves efficiency at the time of the installation of saving；
2. the radiator of the utility model can support PCB luminescence component and radiate to PCB luminescence component, reverberation bowl is mainly used
In the reflection of light, sidelight lens can be such that light refraction passes through and can change the direction of light；
3. the utility model has the advantages of simple structure, easy to operate.
