Description

The automobile lamp that goes between daytime

Technical field

The utility model relates to a kind of automobile lamp that goes between daytime.

Background technology

The automobile lamp " day time running light " that goes between daytime, be a kind of when car engine automatic-opening novel signal lamp.This lamp installation when vehicle is gone by day, improves the visibility of other road users to automobile at body forward structure significantly, increases road safety.The early stage automobile lamp that goes between daytime is that what satisfy that standard-required mostly adopts is based on halogen bulb, but along with the progress of science and technology, and the present automobile that the designs lamp that goes between daytime adopts the led light source of high brightness; Can significantly reduce the electric energy that needs use, increase the life-span of battery, and the most normal long-life more reaches 8000 hours; The service life that almost is equal to vehicle, the lamp but automobile went between daytime is owing to require luminous flux of light source high, and its luminous intensity distribution performance is wanted the centering luminous intensity must not be lower than 400cd and is not higher than 800cd; Be lower than 400cd and just do not have prompting function; Being higher than 800cd then can influence other drivers' sight line, and therefore the generation that causes the accident easily has only the high-power LED of use; To the reasonable distribution and the utilization of its luminous energy, could satisfy basic demand; The high-capacity LED caloric value is big simultaneously; Its optical attenuation equistability receives Influence of Temperature very big; Therefore the heat that reduces and produce when distributing LED work; Becoming go between the daytime key factor of lamp behaviour stability of automobile, also is that can go between the daytime luminous intensity distribution performance of lamp of automobile reach the indispensable factor of country and international standard.More than two factors be that the LED automobile lamp that goes between daytime needs problem demanding prompt solution.

The utility model content

The utility model technical problem to be solved is the deficiency that overcomes prior art, provide a kind of light distribution requirements rationally, good heat dissipation effect, the more stable automobile of the performance lamp that goes between daytime.

The technical scheme that the utility model adopted is: the utility model comprises the aluminium alloy lamp housing, be positioned at the aluminum-based circuit board and the reflector of aluminium alloy lamp housing, be fixedly installed on the said aluminum-based circuit board and pass the LED lamp group of said reflector; Said LED lamp group comprises several LED lamps, and the position that is positioned at said LED lamp on the said reflector is provided with many reflective surfaces.

Said LED lamp group comprises at least three LED lamps; At least three said LED lamp circle distribution is on said reflector; Light the redistributing, superposeing that said many reflective surfaces send said LED lamp group through each reflective surface; Make the center luminous intensity of said LED lamp group be higher than 400cd and in any direction on be lower than 800cd, the illumination that said many reflective surfaces send said LED lamp group is mapped to each 20 ° of reference center's left and right directions, each luminous intensity distribution of 10 ° zone of above-below direction.

The outside of said aluminium alloy lamp housing is provided with radiating fin, and said aluminum-based circuit board is close to said aluminium alloy lamp housing.

Said lamp housing open top end is provided with light transmission piece, and said light transmission piece is pushed down said reflector.

The beneficial effect of the utility model is: since the utility model comprise lamp housing, be positioned at lamp housing wiring board and reflector, be fixedly installed on the said wiring board and pass the LED lamp group of said reflector; The said aluminum-based circuit board and the said aluminium alloy heat-dissipating casing that have good thermal diffusivity through use; Reduce LED and wiring board operating temperature; Improve its heat endurance; Said LED lamp group comprises several LED lamps; The position that is positioned at said LED lamp on the said reflector is provided with many reflective surfaces, and the optical optimization design through to said the above many reflective surface of reflector improves every LEDs light efficiency greatly; Thereby make its luminous intensity distribution performance reach GB23255-2009 " automobile go between daytime lamp luminous intensity distribution performance " and ECE R87 " the unified regulation of the authentication of the lamp that goes between daytime " standard-required about motor vehicle, thus the utility model light distribution requirements rationally, good heat dissipation effect, performance be more stable.
