Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

As illustrated, this many matrix reflective LED head lamps, mainly include lens 1 and lamp body 3, lens 1 and lamp body 3 mutually fasten one cavity of formation, and optical module, heat dissipation element and light modulation part are provided with cavity, and optical module includes distance light Part, dipped beam part, position and DRL parts and turning member, distance light part mainly include high beam reflector 2 and distance light LED core Piece 4, dipped beam part mainly include low beam reflector 7 and dipped beam LED chip group 8, position and DRL parts mainly include LED chip, Photoconduction 10 and heavy wall moulding I 9, DRL and position lamp realize luminous intensity distribution Standard, turning member by photoconduction 11 and light guide plate Mainly include LED chip and heavy wall moulding II 11；Heat dissipation element includes that the PCB support 12 in each functional part is propped up with radiating Frame, heat dissipation element adopt ALDC materials, are that die casting amounts to 5 module radiators, and structure is different；Light modulation part is mainly included Light dimming electric motor 6.High beam reflector 2 is located at the top of distance light LED chip 4, and distance light LED chip 4 is connected with distance light cooling stand 5. Distance light LED chip 4 includes two LEDs, horizontally arranged distribution.Low beam reflector 7 is located at the top of dipped beam LED chip group 8, dipped beam Reflecting mirror 7 is connected with light dimming electric motor 6.Dipped beam LED chip group 8 includes three LEDs, and echelon formation is distributed, following two LED, One LEDs of top.Heavy wall moulding II 11 is connected with PCB support 12.LED chip is driven and is driven using constant-current source.

This utility model does not adopt cooling fan with reduces cost, mainly reaches heat by the distribution of fin and steam vent Amount dissipation effect.This utility model adopts Philip ALTILON light source, the encapsulation of LED using it is transparent, do not absorb luminescent material and serve as a contrast Bottom so that with higher light efficiency, improve the luminous efficacy of LED, reduces light in its internal loss, is provided with reflection Light is reflexed to mirror the surface of semi-conducting material, can increase underlay substrate reflectance, so that as far as possible many light can be saturating Shoot out, reach the purpose for improving luminous efficacy.

Temperature is a key factor for affecting LED performances, and although generation heat low in energy consumption is few for LED, and heat is but all accumulated Inside small chip, the temperature at die junction raises the life-span for not only having influence on LED, and can reduce its luminous effect Can, therefore its problem for radiating can not be ignored, low power LED typically adopts epoxy encapsulation, and its heat conductivity is poor but Also in controlled range；And for the radiating of great power LED especially needs to pay attention to, by being used as envelope from some highly heat-conductive materials Dress substrate can improve the heat-sinking capability of LED itself well, and LED encapsulation can select the advanced ceramics materials such as aluminium oxide and aluminium nitride Material, the pyroconductivity of aluminium oxide is 55 times of epoxy resin, and the pyroconductivity of aluminium nitride is 400 times of epoxy resin, high at present Power LED package substrate is used mostly the aluminum that pyroconductivity is 237W/ (mK), or pyroconductivity is 400W/ (mK) Copper metal package substrate.This utility model fin adopts ALDC materials.Because single led power is very low, luminous flux Less and luminous angle difference is very big, so in the design of LED automobile light fixture, it is general using many LED arrangements, The selection of the lighting angle of LED is also extremely important, and rational lighting angle to can ensure that and reach requirement in lamp distribution performance Under the premise of, the quantity of LED is minimized to reduce power consumption and manufacturing cost.This utility model is completed from 5 great power LEDs Realize distance-light.Dipped beam is, using 3 great power LEDs, as light light distribution requirements must have 15 ° of "cut-off"lines, to prevent from dazzling Mesh causes other road occupations generation vehicle accident, using following 2 LEDs, 1 LEDs of top, by the arrangement of this form Light distribution requirements are reached, while also improving road surface irradiation performance, wherein dimming mode is arranged on mirror support, one of Reflecting mirror can realize luminous intensity distribution Standard after needing light modulation.Distance light realizes that using 2 great power LEDs luminous intensity distribution performance will Ask, while distance-light needs to meet the installation light modulation regulation of motor vehicles, on dimming mode lower angle according on the mirror, left and right Light modulation is fixed on reflecting mirror cooling stand.This utility model is full LED headlamp, and steering indicating light and DRL and position lamp pass through LED light source is realizing.

In addition to the implementation, this utility model can also have other embodiment.All employing equivalents or equivalent change The technical scheme to be formed is changed, the protection domain of this utility model requirement is all fallen within.
