Abstract
The utility model relates to the automobile lighting technical field, in particular to a lighting-emitting diode (LED) automobile headlight holder using a corrugated convex mirror with far light, near light and side light integrated. By adopting of an optical design of the corrugated convex mirror, a good extension effect of the corrugated convex mirror is utilized, and requirements of international spot graphics are met. Therefore, rationality of arrangement of high-power integrated light-source LED chips and structure of a lamp body is guaranteed. In a simple way, steering controlled side-lighting function is achieved.
Description
Affiliated technical field: the utility model relates to the automotive lighting technical field, is a kind of far away, near, sidelight integral LED vehicle front lighting lamp holder that adopts the ripple convex lens.
Background technology: at present, the design of known LED car headlamp mainly is divided into two large types: the one, and column type light source, led chip are arranged in cylinder and top, realize that by reflector and convex lens light beam focuses on, pass by the electric gear mating plate, open, realize dipped beam and far and near effect of light.This class lamp can direct substitution halogen or hernia car light, but its power is subject to the restrictions such as wick diameter and heat radiation factor, can only accomplish 30W at present.The 2nd, figure area source, led chip is arranged on the substrate of integrated optical source according to the spot pattern that GB requires, and realizes that by biconvex mirror light beam focuses on, and subregion, minute loop setting by the distance-light chip realize dipped beam and far and near effect of light.This class lamp can be realized the car light of relatively high power, but because the restriction of graphic length direction, has limited that chip is arranged, the reasonability of lamp body structure, so that the expansion of high power level car light.
Summary of the invention
For the problems referred to above, the technical solution of the utility model is: at first according to lamp power requirement, corresponding integrated light source substrate, heat abstractor etc., (not considering first the requirement of spot pattern length direction) designs simple and direct, the rationally distributed chip arrangement of technique.By selecting the ripple convex lens (seeing Fig. 1) of corresponding extension coefficient, replace outer convex lens again, realize the requirement of GB spot pattern length direction.And outside dipped beam paster zone, small pieces sidelight paster zone is set, thereby realize far away, near, sidelight integral LED vehicle front lighting lamp holder.
Scheme implementation: the luminous flux requirement of at first will be respectively far away, near according to car light, sidelight.Respectively according to formula: luminous flux divided by chip light efficiency (lumens/watt), divided by light fixture leaded light efficient (%), equals required number of chips divided by chip rated power again.According to far away, near, sidelight number of chips, design, layout area.Because biconvex mirror focal imaging, hot spot figure Rotate 180 degree, the dipped beam chip portfolio so will the rectangular region on center line arrange, and a small region (seeing Fig. 2) the sidelight chip portfolio of arranging, the rectangular region of the distance light chip portfolio of arranging under the center line are set at the edge.
Far, closely, the sidelight chip portfolio is respectively by first parallel connection, rear coupled in series, three public termination power cathodes of tandem compound.The positive terminal of (seeing Fig. 3) dipped beam chip portfolio connects by dipping switch with power positive end.Normal heat radiation is played in blower fan and the parallel connection of dipped beam chip portfolio, and temperature compensation function.The positive terminal of distance light and sidelight chip portfolio connects by distance light and sidelight switch with the positive terminal of dipped beam chip portfolio.After dipping switch was opened, the dipped beam of left and right sides car light head was opened; At this moment the distance light switch will be controlled the unlatching of both sides distance light simultaneously; The left and right sides photoswitch is controlled respectively the unlatching of both sides sidelight.
Owing to adopted the optical design of ripple convex lens, utilized the good extension effect of ripple convex lens, reached the requirement of GB spot pattern, ensured that high-power integrated light source led chip is arranged and the reasonability of lamp body structure.And by simple and direct mode, realized that turns to a controlled sidelight function.
The utility model is a kind of far away, near, sidelight integral LED vehicle front lighting lamp holder that adopts the ripple convex lens.It is to be made of institutes such as lamp housing, silica gel ring, convex lens frame, interior convex lens, integrated optical source substrate, base, radiator, blower fan, instant and near light chip portfolios.Its technical characteristics is: outer convex lens is the ripple convex lens, outside the zone of dipped beam chip portfolio, is provided with sidelight chip portfolio zone.

The specific embodiment
Embodiment: a 68W adopts far away, near, the sidelight integral LED vehicle front lighting lamp holder of ripple convex lens.The ripple convex lens of diameter Ф 80cm, extension coefficient 1.8 has been adopted in the outer convex lens (1) at its top design.Evagination mirror holder (2) installs silica gel ring (3) additional the ripple convex lens is tightened on the lamp housing (4), and silica gel ring is thicker, and the trace that can make focal length is regulated (adjust qualified after, sealing).Again fixed mount (7) is fixed on the lamp housing.
Integrated optical source substrate (8) coating heat-conducting cream adopts fastened by screw on base (9).Convex picture frame (6) also is tightened on the integrated optical source substrate with interior convex lens (5).The integrated optical source substrate is fixed on radiator (10), and blower fan (11) is fixed under the radiator.Consist of the removable section of car light.The removable section of car light is added the cover silica gel ring, and in the precession lamp housing (4), silica gel ring is thicker, and the trace that can make focal length is regulated (adjust qualified after, sealing).
Car light design total light flux 13600 lumens, wherein: dipped beam 8000 lumens, distance light 4000 lumens, sidelight 1600 lumens.Appraise and decide whole lamp leaded light efficient 85%, 1 watt of rated power, light efficiency 120 lumens/watt led chips are adopted in design.Because biconvex mirror focal imaging, hot spot figure Rotate 180 degree, the dipped beam chip portfolio (13) so will the rectangular region on center line arrange, and at the border area sidelight chip portfolio (12) of arranging, the rectangular region under the center line distance light chip portfolio (14) of arranging.
Far, closely, three of the sidelight chip public termination power cathodes of tandem compound.The positive terminal of dipped beam chip portfolio connects by dipping switch (15) with power positive end.Normal heat radiation is played in blower fan and the parallel connection of dipped beam chip portfolio, and temperature compensation function.The positive terminal of distance light and sidelight chip portfolio connects by distance light switch (16) and sidelight switch (17) with the positive terminal of dipped beam chip portfolio.After dipping switch was opened, the dipped beam of left and right sides car light head was opened; At this moment the distance light switch will be controlled the unlatching of both sides distance light simultaneously; The left and right sides photoswitch is controlled respectively the unlatching of both sides sidelight.
