For solving this technical problem, the technical scheme that the utility model adopted is as follows:

A kind of electric vehicle illuminating lamp, it includes reflective housing and headlamp, and described headlamp is made of a plurality of LED, fix with reflective housing, the luminous site of described headlamp is in reflective surface the place ahead of reflective housing, described LED serial or parallel connection, and link to each other luminous with battery of electric vehicle by lead.

Described LED is multi-row staggered distribution.

Described electric vehicle illuminating lamp also has left and right steering indicating light, also is to adopt a plurality of LED to be in series or in parallel to form.Described LED forms arrowhead form or arranges more and put.

Described reflective housing is provided with the corresponding bowl-type groove with LED, and described bowl-type groove is provided with through hole, and described LED embeds in the through hole.

Adapted dropping resistor when described LED connects, adapted decompression voltage regulator when LED is in parallel.

It also includes lampshade and backboard, and on reflective housing in the corresponding draw-in groove, fix by screw and reflective housing rear portion by described backboard by some snap fit for described lampshade.

Described electric vehicle illuminating lamp is symmetrical structure, by fixing with electric motor car hold-down support and electric motor car.

The LED of described headlamp has 13, is scattered in 3 rows, and first and third row respectively is that 4, second row are 5, and it is the center symmetrical distribution that other 6 LED arrange the 2nd and the 4th LED with the 2nd respectively.

Reflective housing is the integrative-structure that adopts plastics or resin integral molded plastic to form.

LED utilizes the recombination radiation of semiconductor in conjunction with the carrier in the portion, so do not follow heating, light efficiency height, radiationless, low-power consumption, the spectrum of LED almost all concentrates on visible light frequency band, its luminous efficiency can reach 80-90%, therefore, can improve energy efficiency, extending battery life significantly, in the motionless electric motor car of battery band, and battery has brightness and the light that does not also influence this illuminating lamp under the situation of little electricity, and the life-span of LED itself is also long than incandescent lamp bulb, and continuous illumination can reach more than 60,000 hours.

The beneficial effect of the utility model electric vehicle illuminating lamp is, energy-conservation, durable, optically focused is good, brightness is high, the illumination distance far away, especially do not influence the use of illuminating lamp during power shortage night yet, when turning round, also can play illumination and point out the left and right effect that turns to, and the light emitting diode in this product adopts high-brightness LED to satisfy and the necessary optically focused LED that adopts, so with low cost.
