Abstract

The utility model provides an automobile-used light-emitting diode (LED) light source working under voltage below 48 V. The LED light source comprises an LED module, a lamp cap, a current limiter and a lamp shade, wherein, the LED module comprises one or more LEDs which are connected in series or in parallel; one end of the current limiter is connected with the LED module, and the other end thereof is connected with the lamp cap; the outline of the lamp shade can be plane-shaped, rectangular, circular, or elliptical bulb-shaped, and also can be spherical, cylindrical, conical, or prismatic; the lamp cap can be a straight inserting lamp cap; one, two, three or more pins can be arranged at one end of the lamp cap; a metal radiator is arranged on the pins at the parts connected with the lamp cap; the lamp shade can be made of light-transmitting glass or light-transmitting colloid; and the LED module shaded by the lamp shade can be a white-light LED, a red light LED, or an LED of another color. The utility model can meet the illumination requirements of the inner part, the front part, the side part and the rear part tail light of an automobile; the power of the LED light source can be configured according to the requirements of a lamp; and the modes of the lights are diverse.

Description

A kind of automobile-used LED light source

Technical field

The utility model relates to automobile-used electric light source, particularly is a kind of automobile-used LED lamp.

Background technology

Semiconductor light-emitting-diode LED is a kind of new type electro source, and its basic functional principle is to utilize the solid semiconductor chip as luminescent material.When the LED two ends add voltage, the son that dams in the semiconductor takes place compoundly to cause photo emissions and produce light, the only non-radiative light that is gone out, photochromic pure, light beam concentrated, high, the good temp characteristic of colour rendering index.It has advantages such as electric quantity consumption is low, stable performance, the life-span is long, pollution-free, use is simple.The tradition car light is because power consumption is big, and service life is short, and poor reliability is brought inconvenience to driving at night, and urgent need is a kind of reasonable in design on the market, and lifetime of system is long, can satisfy the illuminator that driving requires.

Summary of the invention

Purpose of the present invention is exactly that a kind of a kind of automobile-used LED light source that is used for vehicling lighting will be provided.It is operated in 48 volts of following power supplys, form by led module, lamp holder, current limiting device, lampshade, led module is made up of one or plurality of LEDs serial or parallel connection, these LED are welded on the circuit board of heat conduction and form led module, one end of current limiting device connects led module, and the other end and lamp holder link.Lampshade seals led module and current limiting device within it, and its profile can be a planar shaped.The lampshade profile is rectangle or garden shape or oval bulb also, can also be spherical cylindrical conical or prismatic.But lamp holder straight cutting lamp holder, one end of lamp holder can have one or two or three or many legs, mutually insulated between leg and the leg and between the shell of leg and lamp holder has symmetrical mount pin on the outer surface of lamp holder, the part that is connected with lamp holder can have metal heat sink.But lampshade transparent glass or printing opacity colloid, it prevents dust, discharges water, but the led module white light LEDs or red-light LED or other color LED that are got up by the lampshade cover, power is changeable.The utility model can satisfy the illumination needs of vehicle interior, front portion, side and rear portion taillight, and its power is by the requirement configuration of lamp.The pattern of lamp can be varied.
