Abstract
The utility model discloses a kind of direct-current air cooling formula automotive LED headlamp, comprise a column type lamp body, the front end of lamp body is provided with a porous venting cover, the rear end of lamp body is provided with a blower fan, the column type surface of lamp body offers several air channels be evenly distributed, the two ends in every bar air channel are communicated with blower fan with porous venting cover respectively, are provided with row's LED lamp bead between the air channel of adjacent two.The utility model utilizes the narrow pipe effect of air-flow, carries out direct-current air cooling to LED lamp bead.The high velocity air that narrow pipe effect produces can sweep along the heat produced during LED lamp bead work to flow out from porous venting cover instantaneously, to reach the object of heat radiation, ensure that the front reliability according to head of LED automobile and service life.The utility model can not only reach the radiating effect identical with liquid cooling technology, and volume is smaller and more exquisite, and structure is more simple.So the utility model can directly load in the auto bulb of H4 or H8 standard, without the need to improving the original assembly of automobile or redesign, greatly save cost.
Description
Technical field
The utility model belongs to the technical field of LED illumination of automobile, is specifically related to a kind of direct-current air cooling formula automotive LED headlamp.
Background technology
Nowadays, LED technology has been widely used on the various vehicles, and such as most motor-driven headlamp have employed LED technology all successively.Although in equivalent brightness situation, LED lamp bead is than the economize on electricity of conventional lights pearl, and because LED lamp bead is highly concentrated in this airtight working environment of lampshade, its heat also high concentration produced, how good heat radiating is exactly a problem needing solution badly.
The heat dissipating method of traditional LED is on LED, directly arrange a heat abstractor, and this mode not only radiating efficiency is relatively low, causes shorten the service life of LED headlamp, and the frequency changing headlamp increases, and substantially increases cost of upkeep.
Current employing circulation fluid refrigeration technique carries out dispelling the heat also comparatively general.But just can reach preferably radiating effect owing to needing more refrigerant (refrigerating fluid), so the size of adopting LED headlamp is in this way often larger, not only directly can not load the head lamp of H4 or H8 standard, too increase the counterweight of automobile simultaneously, add Automobile Design difficulty.
Utility model content
For above-mentioned Problems existing, the utility model provides a kind of direct-current air cooling formula automotive LED headlamp, utilizes the narrow pipe effect of air-flow, carries out direct-current air cooling to LED lamp bead, shines reliability and the service life of head before improve LED automobile.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of direct-current air cooling formula automotive LED headlamp, comprise a column type lamp body, the front end of described lamp body is provided with a porous venting cover, the rear end of described lamp body is provided with a blower fan, the column type surface of described lamp body offers several air channels be evenly distributed, the two ends in air channel described in every bar are communicated with described blower fan with described porous venting cover respectively, are provided with row's LED lamp bead between the described air channel of adjacent two.
Further, described air channel is narrow manage-style road narrow in the middle part of two head breadths.
Further, the rear portion of described lamp body is provided with the adjustable plate for regulating described LED lamp bead light focus, and described adjustable plate is between described blower fan and described LED lamp.
Further, described lamp body is six prismatics or column type.
Further, described LED lamp bead is one or both in dipped beam LED lamp bead and distance light LED lamp bead.
The utility model make use of narrow pipe effect, and its operation principle is as follows:
Narrow pipe effect, when air-flow flows into by opening the valley that landform forms, because air quality can not bulk deposition, so accelerate to flow through valley, wind speed increases.When flowing out valley, air velocity can slow down again.This landform valley, on the impact of air-flow, is called " funnelling ", also known as " narrow pipe effect ".
Blower fan rotates and produces air-flow, and gas flows in air channel, and when through middle part stenosis, because gas has compressibility, flow velocity is accelerated, and density also can increase.High velocity air can sweep along the heat produced during LED lamp bead work to flow out from porous venting cover, to reach the object of heat radiation instantaneously.
The beneficial effects of the utility model are as follows:
1, the utility model utilizes the narrow pipe effect of air-flow, carries out direct-current air cooling to LED lamp bead.The high velocity air that narrow pipe effect produces can sweep along the heat produced during LED lamp bead work to flow out from porous venting cover instantaneously, and to reach the object of heat radiation, ensure that the front reliability according to head of LED automobile and service life, making to change lamp all the life becomes possibility.
2, the utility model can not only reach the radiating effect identical with liquid cooling technology, and by comparison, volume of the present utility model is smaller and more exquisite, and structure is more simple.Just because of this, the utility model can directly load in the auto bulb of H4 or H8 standard, without the need to improving the original assembly of automobile or redesign, has greatly saved cost.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
