Abstract
The invention discloses an automobile headlamp, which comprises a reflective bowl, a lampshade and a lamp holder provided with multiple LED (Light-emitting Diode) lamps, wherein the lamp holder is located behind the reflective bowl. The automobile headlamp is characterized in that each LED lamp is provided with a flexible light pipe penetrating through the reflective bowl and facing to a focal point part of the reflective bowl; saw-toothed reflection edges extending along the circumference are arranged on the lower half part of the reflective bowl; each reflection edge is provided with an external reflection plane and an internal reflection plane, so that forward and upward reflected light can be reflected to the upper part and the internal part of the reflective bowl again, and meanwhile, the forward and downward light of the reflective bowl is maintained. Therefore, the pavement irradiation is ensured, meanwhile, the irradiation angle can be controlled, the dazzling light in the front upper part is reduced, and the driving safety is greatly improved.
Description
Technical field
The present invention relates to auto parts machinery field, be specifically related to car headlamp.
Background technology
Along with the development of LED illumination technology, increasing automobile lamp adopts LED, LED car lamp is all utilize the LED array of multiple dispersion to realize throwing light on, even if having employed reflector, also all LED all cannot be placed on the focus place of reflector, other structure therefore must be adopted to become directional light to make scattered light, also have problem be exactly to its front to the irradiation of upper angle often cause opposite meeting driver, pedestrian dazzling, do not see road surface at the moment, cause potential safety hazard.
Summary of the invention
For above-mentioned technical problem, the object of the present invention is to provide a kind of anti-glare LED car light, scattered light can be made to become directional light, avoid causing dazzling to opposite meeting driver or pedestrian simultaneously.
The technical scheme solved the problems of the technologies described above is as follows: car headlamp, comprise reflector, lampshade and be provided with the lamp socket of multiple LED, described lamp socket is positioned at the rear of reflector, it is characterized in that: described LED is provided with one through reflector and towards the flexible light-conducting pipe at reflector focus place, the latter half of described reflector is provided with the jagged reflection rib circumferentially extended, and each reflection rib has external reflectance plane and interior reflective surface.
Rear side and the described lamp socket of described reflector are shrouded by the cover body that an inside is provided with reflector layer.
Have employed such scheme, adopt flexible light-conducting pipe to make heat radiation light become directional light, there is good practicality; The design of the latter half reflecting surface zigzag reflection bar of reflector in addition, original reverberation upwards is forward reflected back reflector top and inside again, remain the light that reflector is downward forward simultaneously, while such guarantee road surface is irradiated, irradiating angle can also be controlled, reduce the dazzling light of front upper place, greatly improve the security of driving.
Accompanying drawing explanation
Fig. 1 is the structural representation of car headlamp of the present invention.
Fig. 2 is A place enlarged drawing in Fig. 1 of the present invention.
1 is reflection rib, and 2 is reflector, and 3 is cover body, and 4 is lamp socket, and 5 is LED, and 6 is flexible light-conducting pipe, and 7 is lampshade, and 11 is external reflectance plane, and 12 is interior reflective surface.
Detailed description of the invention
See figures.1.and.2, car headlamp, comprise reflector 2, lampshade 7 and be provided with the lamp socket 4 of multiple LED 5, described lamp socket 4 is positioned at the rear of reflector 2, described LED 5 is provided with one through reflector 2 and towards the flexible light-conducting pipe 6 at reflector 2 focus place, the latter half of described reflector 2 is provided with the jagged reflection rib 1 circumferentially extended, and each reflection rib 1 has external reflectance plane 11 and interior reflective surface 12.
The rear side of described reflector 2 and described lamp socket 4 are shrouded by the cover body 3 that an inside is provided with reflector layer.
Adopt flexible light-conducting pipe to make heat radiation light become directional light, there is good practicality; The design of the latter half reflecting surface zigzag reflection bar of reflector in addition, original reverberation upwards is forward reflected back reflector top and inside again, remain the light that reflector is downward forward simultaneously, while such guarantee road surface is irradiated, irradiating angle can also be controlled, reduce the dazzling light of front upper place, greatly improve the security of driving.
