Description
Technical field
The present invention relates to lamp for automobile, especially a kind of Auto Rear Fog Lamp.
Background technique
Rear Fog Lamp vehicle lamp light source currently on the market is mainly light bulb and LED.Due to bulb source design by space, make
The limitation for the reasons such as type, service life be short；And it is all environmentally protective in promotion all over the world, the color temperature adjustment range of especially LED is big, has
Conducive to use, small power consumption low with operating voltage, so LED will be widely used automobile tool lamp as green light source
In use.The LED Rear Fog Lamp, LED are the luminous tubes with diode characteristic, it can only one direction energization.It is usually bright
Degree output is directly proportional to by LED current, but great power LED will appear saturated phenomenon under high current, and luminous efficiency can be substantially
Degree decline, or even failure.Therefore great power LED using electric current no more than rated value as defined in it.So with regard to this big function
It for the LED of rate, needs to increase driving power, which is mounted on lamp interior to guarantee the waterproofness of lamps and lanterns.Institute
The LED Rear Fog Lamp stated, can generate a large amount of heat at work.When multiple LED are densely arranged, the aggregation of heat will be more
Seriously.If this heat does not shed as early as possible, the following fuel factor will clearly, this will cause chip interior heat
A series of problems, such as assembling, leading to light efficiency decline and reduced service life.So in LED Rear Fog Lamp tool, external heat sink
Structure design it is very crucial, directly influence the heat-sinking capability of whole system.
Summary of the invention
To solve the above problems, the purpose of the present invention is to provide a kind of Auto Rear Fog Lamp, especially a kind of automobile LED
Rear Fog Lamp tool, has good external heat sink effect.
The technical scheme is that be accomplished by the following way: a kind of Auto Rear Fog Lamp is it is characterized by: by light distribution
Mirror, lamp housing, reflector, aluminum-based circuit board, LED light, driving power and aluminum substrate composition, reflector, driving power and aluminium heat dissipation
Block is screwed on lamp housing, it is characterised in that: the LED light is fixed on the reflector of lamp housing.
The LED light is the LED of more 0.25W, and aluminum-based circuit board is controlled by driving power uses electric current.
The aluminium radiating block is equipped with the gear piece with multiple heat dissipations.
The lens inner surface is coated with one layer of anti-film that hazes；And venthole there are two being set at the lamp housing back side.
Structure of the invention uses the LED for being more 0.25W, making for aluminum-based circuit board is controlled by driving power
With electric current, the high photosynthetic efficiency of LED Rear Fog Lamp ensure that.Heat dissipation gear piece on aluminium radiating block, available better heat dissipation effect.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Known by Fig. 1, a kind of Auto Rear Fog Lamp it is characterized by: by lens 1, lamp housing 2, reflector 3, aluminum-based circuit board 4,
LED light 5, driving power 6 and aluminium radiating block 7 form, and reflector 3, driving power 6 and aluminium radiating block 7 are screwed in lamp housing 2
On, the LED light 5 is fixed on the reflector 3 of lamp housing 2.LED light 5 be more 0.25W LED, by driving power 6 come
Control aluminum-based circuit board 4 uses electric current.Aluminium radiating block 7 is equipped with the gear piece with multiple heat dissipations；Table in the lens 1
Face is coated with one layer of anti-film that hazes；And set at 2 back side of lamp housing there are two venthole, a venthole arranges the temperature of lamp interior
Out, another venthole enters new air, and the temperature of lamp interior is adjusted, and is hazed by anti-on lens 1
When film prevents the extinguishing of LED light 5 in lamps and lanterns, the situation that hazes of new air outflow appearance.
Aluminium radiating block 7 of the invention is the good conductor of one piece of heat with many heat dissipation gear pieces.When designing radiator structure,
Aluminum-based circuit board 7 will have certain thickness first, to resist the impact of transient thermal load.When energized, LED driving electricity
Source drives aluminum-based circuit board 7 that certain current range is kept to be lighted, and the heat that LED is generated in ignition passes through first
Aluminum-based circuit board is transmitted on conduction estersil, is transmitted on aluminium radiating block by conduction estersil again later, then by aluminium radiating block 7
Bottom plate by the heat of generation from lamp interior export, distribute heat to sky finally by the gear piece structure on aluminium radiating block 7
In compression ring border.
