Abstract

The utility model discloses an automobile light-emitting diode (LED) daytime running light. The automobile LED daytime running light comprises a base, a transparent cover and LED luminous chips, wherein the transparent cover is arranged on the base, and the LED luminous chips are arranged on a printed circuit board (PCB) which is arranged on one side of the base; and half-slotted reflection cups are opposite to the LED luminous chips which are toward the inner side of the PCB board. The automobile LED daytime running light has the advantages of downy light rays without glare, simple structure and convenience in installation and maintenance, and forms an area light source.

Description

Automobile LED day portable lighter

Technical field

The utility model relates to a kind of automobile LED day portable lighter or Fog-proof light that is used for before and after the automobile.

Background technology

The existing LED day portable lighter that is used for automobile generally comprises an arc-shaped base, on arc-shaped base, is provided with a plurality of prefocus cups of arranging continuously, is provided with a LED luminescence chip in the bottom of each prefocus cup, on said base, is provided with a translucent cover.The light that the LED luminescence chip sends is behind prefocus cup optically focused, through translucent cover and to front irradiation.This LED day portable lighter has the brightness height, energy-saving advantages, still, and this defective that has the following aspects, the one, this LED day portable lighter looks like by spot light one by one the people and forms line source in use, when turning on light, seems not too attractive in appearance; The 2nd, this LED day portable lighter sends after through optically focused, and is dazzling especially when using at night, especially evening meeting the time, to relatively and the pilot's line of vision on the vehicle of row has very big influence, have traffic safety hidden danger; The 3rd, existing LED day portable lighter, because the corresponding LED luminescence chip of each prefocus cup, there is complex structure like this in the corresponding circuit board of each luminescence chip, installs and keep in repair the problem that all compares difficulty.

The utility model content

The purpose of the utility model is to the problems referred to above, provides a kind of light soft not dazzling automobile LED day portable lighter to society.

Another purpose of the utility model is: to society a kind of automobile LED day portable lighter that is area source of having seen is provided.

Another purpose of the utility model is: to society automobile LED day portable lighter a kind of simple in structure, easy to installation and maintenance is provided.

The technical scheme of the utility model is: design a kind of automobile LED day portable lighter; Comprise base, be arranged on the translucent cover on the said base and be arranged on the LED luminescence chip on the pcb board; Said pcb board is arranged on said base one side; Said LED luminescence chip is being provided with half flute profile reflector towards interior with respect to the LED luminescence chip.

As improvement, on the inner surface of said reflector, be provided with the reflex streak that protrudes from inner surface to the utility model.

As the further improvement to the utility model, said reflex streak interweaves in length and breadth and constitutes reflective grid.

Further improvement as to the utility model is provided with the refraction striped on the inner surface of said translucent cover.

As the further improvement to the utility model, said LED luminescence chip is more than two, and is arranged on the same pcb board; Said half flute profile reflector is more than two, and interconnects and become one.

Dorsal part at said pcb board is provided with heat sink.

As the further improvement to the utility model, said heat sink is aluminium sheet or aluminium alloy plate.

As the further improvement to the utility model, said base is made with engineering plastics.

As the further improvement to the utility model, said translucent cover is the plastic, transparent cover.

As the further improvement to the utility model, said translucent cover and base are fastened and connected through grab and convex edge each other.

The utility model is owing to adopted said pcb board to be arranged on said base one side, and said LED luminescence chip is towards interior, in the structure that is provided with half flute profile reflector with respect to the LED luminescence chip; With penetrating light behind traditional optically focused, change the refraction back into and penetrate light, especially on the inner surface of reflector, be provided with the reflex streak that protrudes from inner surface; Diffusion effect after it is reflective can be better; Therefore, it is soft not dazzling to the utlity model has light, has seen the advantage that is area source; In addition; The utility model has also adopted plural LED luminescence chip has been arranged on the same pcb board, and plural said half flute profile reflector interconnected becomes one, like this; The utility model also has advantage simple in structure, easy to installation and maintenance.
