Abstract
The invention relates to an LED automobile headlamp which comprises an LED chip (1), a copper substrate (2), a radiator (3), a collimator (4) and a free-form surface microlens array (5). The LED chip is welded to the copper substrate, the copper substrate, the collimator and the free-form surface microlens array are all mounted on the radiator, the light-emitting face of the LED chip faces the incident plane of the collimator, and light passes through the collimator and then is emitted out as parallel light beams which are vertically incident to the incident plane of the free-form surface microlens array. According to the LED automobile headlamp, the special radiator is used, the radiating effect is good, a light source is stable, the service life is long, the number of parts of the microlens array type headlamp is few, the structure is simple and stable, mounting is convenient, the radiating efficiency is high, there is no need of a light barrier for light distribution, the consumption to light energy of a light distribution system is reduced, and the utilization rate of the light energy is improved.
Description
Technical field
The invention belongs to luminescence display technical field, be specifically related to a kind of LED car headlamp.
Background technology
LED light source has long, energy-efficient, the advantage such as volume is little, environmental protection of life-span, extensively be applied by aspects such as lamps in brake lamp, steering indicating light, taillight and the instrument of vehicle at present, research in headlamp application is also more and more, and LED is about to become the main flow in vehicle lamp light source market.Along with the application of LED in Vehicular illumination system constantly expanded, the improving constantly of application technology, LED will replace traditional incandescent lamp and halogen tungsten lamp gradually, becomes " the 4th generation " light source of car light, and this will be also the development trend of the application of car lighting from now on.
But the heat dissipation problem of LED car headlamp is one of technical problem urgently to be resolved hurrily in this area, it is related to the service life of LED and the aesthetics of light source.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of LED car headlamp, simple and stable structure, be convenient to install, radiating efficiency is high and do not need light barrier to carry out luminous intensity distribution, has reduced the loss of light distributing system to luminous energy, has improved the efficiency of light energy utilization.
Technical scheme of the present invention is as follows.
A kind of LED car headlamp, comprise LED chip 1, copper base 2 and radiator 3, collimater 4 and free curved surface micro-lens array 5, LED chip is welded on copper base, copper base, collimater and free curved surface micro-lens array are installed on radiator, the light-emitting area of LED chip is towards the plane of incidence of collimater, light after collimater with collimated light beam outgoing, and the plane of incidence of vertical incidence free curved surface micro-lens array;
Described radiator 3 comprises a main structure body, this main structure body is made up of structure seat and many groups conducting strip of being arranged on structure seat, described conducting strip is the fin type structure that rule is arranged, described structure seat and conducting strip are processed by pure aluminum material combination, described structure seat and described conducting strip are the stamping forming combining structure of integral type, described structure seat is the combining structure not being fixedly connected with described conducting strip, and structure seat and conducting strip adopt 1060 high heat conduction aluminium flakes to combine.
Preferably, described radiator thermal conductivity factor is not less than 53.
Compared with prior art, tool of the present invention has the following advantages and technique effect: LED car headlamp provided by the invention has adopted specific radiator, good heat dissipation effect, light stability, long service life, microlens array type headlamp spare and accessory parts are few, simple and stable structure, be convenient to install, radiating efficiency is high and do not need light barrier to carry out luminous intensity distribution, has reduced the loss of light distributing system to luminous energy, has improved the efficiency of light energy utilization.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of LED car headlamp of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.In accompanying drawing 1:
A kind of LED car headlamp, comprise LED chip 1, copper base 2 and radiator 3, collimater 4 and free curved surface micro-lens array 5, LED chip is welded on copper base, copper base, collimater and free curved surface micro-lens array are installed on radiator, the light-emitting area of LED chip is towards the plane of incidence of collimater, light after collimater with collimated light beam outgoing, and the plane of incidence of vertical incidence free curved surface micro-lens array; Described radiator 3 comprises a main structure body, this main structure body is made up of structure seat and many groups conducting strip of being arranged on structure seat, described conducting strip is the fin type structure that rule is arranged, described structure seat and conducting strip are processed by pure aluminum material combination, described structure seat and described conducting strip are the stamping forming combining structure of integral type, described structure seat is the combining structure not being fixedly connected with described conducting strip, and structure seat and conducting strip adopt 1060 high heat conduction aluminium flakes to combine.Described radiator thermal conductivity factor is 55.
LED car headlamp provided by the invention has adopted specific radiator, good heat dissipation effect, light stability, long service life, microlens array type headlamp spare and accessory parts are few, simple and stable structure, be convenient to install, radiating efficiency is high and do not need light barrier to carry out luminous intensity distribution, reduce the loss of light distributing system to luminous energy, improved the efficiency of light energy utilization.
Although above-described embodiment has been made detailed description to the present invention; but it is only the present invention's part embodiment; rather than whole embodiment, people can also obtain other embodiment according to the present embodiment under without creative prerequisite, and these embodiment belong to protection domain of the present invention.
