Description
Technical field
The utility model relates to lighting device for vehicle fields, specifically, being to be related to a kind of integral LED car light.
Background technique
In existing automotive illumination applications, with being most widely used for halogen lamp, since halogen lamp is shone using tungsten wire,
And the light efficiency of halogen lamp is low, the service life is short, present a part of automobile begins to use LED light replacing halogen lamp as the vehicle of automobile
Lamp.But since the LED chip that LED light uses generates a large amount of heat at work, once the temperature of LED chip is excessively high, it is easy
There is the phenomenon that LED chip is burnt out, influences the service life of LED car lamp.Therefore, how to solve the problems, such as LED chip heat dissipation at
For the key technology of LED car lamp, and the key factor of raising LED car lamp power.
It is provided with radiator and substrate in existing some LED car lamps, LED chip is encapsulated on substrate, and substrate
It is thermally connected with radiator, such as LED substrate is directly contacted with radiator.In this way, the heat that LED chip generates when working passes through base
Plate is conducted to radiator, and is dispersed into air in time by radiator.In order to improve radiating efficiency, existing some LED vehicles
Lamp is provided with fan in one end of radiator, accelerates the flowing of air by the wind that fan is blown out, to accelerate distributing for heat.
But existing LED car lamp fan is the other end that radiator is blowed to from one end of radiator, due to LED car lamp
It is to be installed along substantially horizontal direction, the wind of fan blowout is also to blow out along horizontal direction.And hot-air is often along lead
Hammer direction flows up, and therefore, the fan set-up mode of existing LED car lamp is unfavorable for the flowing of hot-air, and heat dissipation effect is not
Obviously, LED car lamp is caused not to be available high-power LED chip, the brightness of illumination of LED car lamp can not improve.
If necessary to use high-power LED chip, then need to increase the volume of radiator, this will lead to LED car lamp
Volume it is larger, be often unfavorable for the installation of LED car lamp.On the other hand, after the halogen lamp damage that existing automobile uses, one
A little car owners are desirable for LED car lamp replacing halogen lamp, once the volume of LED car lamp is excessive, will be unable to be installed to and are formerly used for pacifying
In the lamp shade body for filling halogen lamp, the popularization and use of LED car lamp are limited.
Summary of the invention
The purpose of the utility model is to provide a kind of integral LED car lights of good heat dissipation effect.
To achieve the above object, a kind of integral LED car light provided by the utility model includes radiator, and radiator has
Multi-disc cooling fin, radiator are provided at least one optical transmission window；It further include substrate, at least part of substrate is located at radiator
It is interior, it is respectively arranged with LED chip on two opposite surfaces of substrate, LED chip is in optical transmission window, and substrate and radiator
It is thermally connected；Wherein, it is additionally provided with fan in radiator, on the installation direction perpendicular to integral LED car light, fan is located at base
The lower section of plate, and cooling fin is located at the top of fan, the blowing direction of fan is perpendicular to installation direction.
By above scheme as it can be seen that being arranged fan in radiator, and radiator is located under substrate and cooling fin
Side, in this way, the wind of fan blowout from the bottom up pass through cooling fin and substrate, to make the heat on substrate and cooling fin empty
Gas rapidly rises to which quick heat guides, and the heat that LED chip generates avoids the temperature mistake of substrate also with regard to Quick diffusing
Work that is high and influencing LED chip.
One Preferable scheme is that, multi-disc cooling fin is arranged in parallel, and the plane where cooling fin is parallel to fan
Blowing direction.
It can be seen that having gap between multi-disc cooling fin, the contact area of cooling fin and air can be increased, thus fastly
The distributing heat into air of speed, improves the radiating efficiency of LED car lamp.
Further embodiment is that integral LED car light is additionally provided with power socket, and power socket setting is separate on a heat sink
One end of LED chip；Multi-disc cooling fin is between LED chip and power socket, and one end of certainly close LED chip is to close to electricity
One end of source(-)holder, multi-disc cooling fin are gradually incremented by relative to the height of fan.
As it can be seen that close to LED chip one end cooling fin height it is smaller, and close to power socket fin height compared with
Height can may insure that in this way LED chip issues to avoid the light for blocking LED chip sending due to the excessive height because of cooling fin
Light can be incident in reflector, and then ensure that the light emission luminance of LED car lamp.
Further embodiment is that thickening heat-conducting part is provided on radiator, on perpendicular to installation direction, thickeies heat-conducting part
Positioned at the lower section of LED chip, further, one end and a piece of cooling fin for thickening heat-conducting part are adjacent
It can be seen that thickening heat-conducting part by setting, heat can be allowed quickly to pass through thickening heat-conducting part and conducted to heat dissipation
Piece improves the radiating efficiency of LED car lamp.
One optional scheme is that hot device is provided with mounting base, and mounting base is located at the one end of cooling fin far from LED chip,
And mounting base is fluted close to the setting of the middle part of integral LED car light axis, groove is recessed to LED chip direction.
As it can be seen that groove is arranged in mounting base, it can be ensured that the fastener in LED car lamp installation on spot lamp holder can be detained
It closes in groove, so that LED car lamp is fixed in spot lamp holder, it is ensured that the firm installation of car light.Also, the utility model
LED car lamp is identical as existing halogen lamp size, can be convenient replacement halogen lamp.
Further scheme is that mounting base is provided at least one locating piece, and the peripheral wall of locating piece self installation seat is along peace
Dress seat extends radially outwardly；Plane where the symmetrical center line and substrate of locating piece tilts.
It can be seen that the symmetrical center line of locating piece is not Chong Die with the plane where substrate, in this way, after installation
The substrate of LED car lamp and plummet face shape lesser angle at an angle, can satisfy different regions to car light light spot shape
It is required that.
Further scheme is that LED chip includes dipped beam LED chip and distance light LED chip；Screening is provided on radiator
Light part, on perpendicular to installation direction, shading piece is in the lower section of dipped beam LED chip.
As it can be seen that the light of dipped beam LED chip sending is blocked by shading piece, to avoid dipped beam LED chip to issuing
Light out is incident in reflector, so that the light for avoiding dipped beam LED chip from issuing is reflected from the top half of reflector
It goes, to form dipped beam hot spot.
Further scheme is that radiator includes two pieces and is mutually butted radiator, and cooling fin is symmetrically arranged in two pieces
On radiator, it is preferred that substrate is clamped between two pieces of radiators.
It can be seen that radiator is arranged to two radiators, when forming LED car lamp, LED chip can will be welded with
Substrate be placed between two radiators, and two radiators are linked together using screw etc..In this way, LED car lamp
Assembling is very simple, reduces the production cost of LED car lamp.
