Description

A kind of LED front combination lamp illuminator

Technical field

The utility model belongs to LED auto lamp technical field, in particular to a kind of LED front combination lamp illuminator.

Background technology

Along with development and the maturation of LED manufacturing technology, and the progressively decline of production cost, LED light source has started to be widely used in the fields such as auto lamp, special lighting light fixture, public illumination, has huge development potentiality, is considered to 21 century light source most with prospects.

As the requisite safety component of running car, the effect of automobile lamp aspect automobile active safety is most important.LED reliability is strong, long service life, excitation are high, fast response time, volume urine bring the advantages such as remarkable variation in design, to automobile appearance, makes it aspect outer illumination of car, obtain more and more general application.Enter 21st century, LED car light has become the new lover of automobile trend, is widely used on the signal lamp such as steering indicating light, Brake lamp.In addition in recent years, people are more and more higher to the energy-conservation cry of automobile environment-protection, and the advantage of LED energy-conserving and environment-protective has also caused people's extensive concern, and this provides great space for the application of LED on automobile lamp.

Current LED auto lamp mostly on the market is the taillight such as Brake lamp, rear directional signal lamp, and every kind of light fixture is independently to separate.The related LED front combination lamp illuminator of the utility model is headlight signal lamp, and by daytime portable lighter, front directional combine and form LED illuminator.

Utility model content

The utility model is for a kind of applicable cases of LED front combination lamp illuminator, designed a kind of by LED front combination lamp illuminator that daytime, portable lighter and front directional formed.

The technical solution adopted in the utility model is as follows: a kind of LED front combination lamp illuminator, comprise portable lighter in daytime, front directional, and be divided into LED module and control module, it is characterized in that, described LED front combination lamp illuminator adopts electric capacity and resistance parallel connection to protect; Adopt the electric current of the mode control LED of resistance current limliting, respectively to daytime portable lighter and front directional control; LED adopts the mode of string series-parallel connection to arrange; Wiring board comprises LED board and control panel.Adopt and cushion transient voltage and filtering in the mode of input shunt capacitance and resistance, LED is played a protective role.Daytime, portable lighter and front directional adopted respectively the electric current of the mode control LED of 2 2W resistance parallel connection.Daytime, portable lighter and front directional LED divided 4 tunnel parallel connections, the series connection of 3, every road, string series-parallel connection.LED adopts high-power Piranha LED, and LED is all arranged on LED board, and LED board divides two parts; adopt FPCB; the relevant components and parts of Current Control and circuit protection are arranged on control panel, and control panel adopts epoxy PCB, and LED board and control panel link together and be combined into whole lamp.Connected mode between PCB layout and different plate has been carried out to specialized designs.

The beneficial effects of the utility model are: by carrying out filtering and play cushioning effect in the time that unlatching, shutoff and input voltage float at input shunt capacitance and resistance, effectively holding circuit, improves the quality of products; Adopt the mode current limliting of high-power resistance parallel connection except improving power, can also control more accurately LED electric current, reach the light distribution requirements of product; LED adopts the mode of string series-parallel connection can ensure that other LED can normally work in the time having 1 LEDs to open circuit inefficacy; By LED board is separated with control panel, make the LED uncontrolled part warming-up effect of dispelling the heat, effectively reduce LED light decay; LED board FPCB used is divided into two parts, effectively avoid the defect such as processing difficulties, percent defective height causing because product size is long, reduce product Material Cost and processing cost, add stiffening plate at bottom FPCB simultaneously, convenient and reliable while making it can ensure again to assemble with shell in meeting whole lamp modeling requirement; Input and output wire harness is welded on control panel by connector, strengthens reliability and is easy to welding.
