Description

A kind of structure of automobile headlamp LED lamplight module
Technical field
The invention belongs to LED automobile illumination technical fields, in particular to a kind of automobile headlamp LED lamplight module Structure.
Background technology
With the gradually decline of the continuous development of LED manufacture technology and maturation and production cost, LED light source has been opened Beginning is widely used in the fields such as auto lamp, special lighting lamps and lanterns, public illumination, has huge development potentiality, it is considered to be 21 Century light source most with prospects.
As the essential safety component of running car, effect of the automobile lamp in terms of automobile active safety to close weight It wants.LED is highly reliable, service life is long, excitation purity is high, fast response time, small convenient for design, to automobile appearance bring Zhuo The advantages that more changing makes it obtain more and more common application in terms of illumination outside vehicle.Into 21st century, LED car lamp is Through the new lover as automobile trend, it is widely used on the signal lamps such as steering indicating light, Brake lamp.In addition in recent years, people couple The energy-efficient cry of automobile environment-protection is higher and higher, and the advantages of LED energy conservation and environmental protections also results in the extensive concern of people, this is LED Application on automobile lamp provides great space.
LED automobile lamp on the market is chiefly used in rear indicator light at present, and single LED power need not be solved in 0.2W or so Certainly LED heat problem, LED lamplight module design are relatively easy, it is easy to just reach the requirement in terms of reliability, involved by the present invention And LED lamplight module in automobile headlamp, LED lamplight module function to be daytime running lamps, using the LED of single 0.5W, The heat of LED sent out needs just reduce by rational structure design, increases the reliability of product.
Invention content
Present invention solves the technical problem that:A kind of structure of automobile headlamp LED lamplight module is provided, LED lamplight module Structure size is 140mm (L) × 20mm (W) X32mm (H), and the structure of LED lamplight module includes plastic stent, LED light source mould Block, LED drive control modules.
Technical scheme is as follows:
Plastic stent material is heat safe PC/ABS polymeric materials, and injection molding, there are six ladders in plastic stent front Facet, each facet correspond to the LED in LED light source module, and LED light source module is riveted on plastic stent front;LED Drive control module is fastened on the back side of plastic stent with screw, one pressing plate of LED drive module input terminal two lines beam and Screw is fastened on the plastic stent back side, and vehicle vibration is avoided to damage LED drive control modules;LED light source module is by FPCB, heat dissipation Aluminium flake, LED lamp bead are constituted;LED is welded on the fronts FPCB, and radiating aluminium sheet is bonded in the back sides FPCB, and the heat that LED is sent out passes through aluminium Piece radiates.
