Description
Affiliated technical field: the present invention relates to the automotive lighting technical field, is a kind of highly integrated LED car headlamp assembly.
Background technology: at present, known LED car headlamp also is in research and development, trial production stage, and the instant and near light lamp is to be divided into two cover mechanisms in development, trial production.
Summary of the invention
Technical scheme of the present invention: for solving the simplification problem of integrity problem that the LED car headlamp uses, production technology; At first design, adopted high-power LED chip; By the requirement of arranging of instant and near light matrix; Integrated being encapsulated on the same LED high power module, as the main light source of car headlamp, and to main light source employing PPTC control mode; Adopted controlled active heat removal mode simultaneously, controlled the operating temperature of LED high power module, ensured that whole lamp service life and car are synchronous; Be the regional specification requirement of light and shade that reaches the illumination pattern, and realize the high light efficiency illumination of light fixture, design, adopted the biconvex mirror type of focusing; More than three aspects constituted the core technology of the integrated headlamp head of instant and near light.The present invention as lampet, is provided with into assembly to fog lamp, steering indicating light with the dipped headlights current limliting assembly of connecting in addition, has realized highly integrated LED car headlamp assembly.
Scheme implementation at first will be confirmed specification, the quantity of led chip according to luminous flux requirement, the rated power of led chip, the photoelectric transformation efficiency (lumens/watt) of instant and near light high-power LED module.That is: luminous flux divided by photoelectric conversion rate, draws led chip quantity divided by whole lamp leaded light efficient divided by chip rated power again.According to the instant and near light number of chips; Design, the matrix of arranging are arranged (because biconvex mirror focal imaging by the hot spot figure requirement of GB light and shade zone; Hot spot figure Rotate 180 degree) the dipped beam bar shaped chipset of arranging on the center line, the distance light rectangle of arranging under center line chipset.The dipped beam chip portfolio passes through also, series connection, connects with the parallel connection combination of corresponding PPTC thermistor and thresholding resistance again, constitutes controlled LED dipped headlights, controlled by the dipped headlights switch.The distance light chip portfolio passes through also, series connection, connects with the parallel connection combination of corresponding PPTC thermistor and thresholding resistance again, constitutes controlled LED high beam, controlled by main furnace building light switch.The dipped beam positive terminal is connected with the parallel connection combination of corresponding PTC thermistor and current-limiting resistance in addition, constitutes controlled LED lampet, controlled by the lampet switch.
Controlled active heat removal mode is about to the instant and near light led module and applies heat-conducting cream, is fastened on the heat radiation aluminium section bar.The NTC negative tempperature coefficient thermistor also is fastened on the heat radiation aluminium section bar, and with the blower fan windings in series, constitute the limit temperature control system.Both ensure the led module groundwork under constant temperature, made the operation of blower fan gap again, ensured service life.
The little convex lens area of the biconvex mirror type of focusing is larger than led module; At first it being close to led module is fixed on the heat radiation aluminium section bar; Big convex lens diameter is about 1.6 times of little convex lens, and adjust its spacing and realize focusing on little convex lens, thus corresponding structure size on definite lamp holder frame.The focusing accuracy claimed range broad here, after mould molding is produced, need not accurate adjustment.
Because the integrated headlamp head of instant and near light quality is bigger, lamp holder frame angular adjustment should adopt turbine and worm mechanism, regulates accurately long-time running, the difficult displacement that produces of jolting like this.The heat radiation aluminium section bar of lamp holder and the assembly of blower fan need be exposed at assembly and mould outside the shell, and displacement is arranged during adjustment, need to adopt ripple type type circle to seal.
Highly integrated LED car headlamp assembly of the present invention is to be moulded institute such as shell to constitute by big convex lens, steering indicating light LED area source, steering indicating light reflection shield, fog lamp LED area source, fog lamp reflection shield, cooling fan, high power module heat radiation aluminium section bar, O-ring seal, steering indicating light heat radiation aluminium section bar, fog lamp heat radiation aluminium section bar, lamp holder adjustment rack, far and near light led module, little convex lens, lampshade, assembly.
Its major technique characteristic is: the matrix of led chip on instant and near light lamp high-power LED module is to arrange by the hot spot figure requirement of GB light and shade zone, lines up the dipped beam stripe matrix on the center line, lines up the distance light rectangular matrix under the center line.The dipped beam chip portfolio passes through also, series connection, connects with the parallel connection combination of corresponding PPTC thermistor and thresholding resistance again, constitutes controlled LED dipped headlights.The distance light chip portfolio passes through also, series connection, connects with the parallel connection combination of corresponding PPTC thermistor and thresholding resistance again, constitutes controlled LED high beam.The dipped beam positive terminal is connected with the parallel connection combination of corresponding PTC thermistor and current-limiting resistance in addition, constitutes controlled LED lampet.The instant and near light high-power LED module is applied heat-conducting cream, be fastened on the heat radiation aluminium section bar.The NTC negative tempperature coefficient thermistor also is fastened on the heat radiation aluminium section bar, and with the blower fan windings in series, constitute the limit temperature control system.The little convex lens area of the biconvex mirror type of focusing is larger than led module; At first it being close to led module is fixed on the heat radiation aluminium section bar; Big convex lens diameter is about 1.6 times of little convex lens, and adjust its spacing and realize focusing on little convex lens, thus corresponding structure size on definite lamp holder frame.
