Abstract
An automotive rear fog lamp comprises a lens (1), a lamp housing (2), a reflector bowl (3), an aluminum based PCB (4), an LED lamp (5), a driving power supply (6) and aluminum radiating blocks (7). The reflector bowl (3), the driving power supply (6) and the aluminum radiating blocks (7) are fixed on the lamp housing (2) by virtue of screws. The automotive rear fog lamp is characterized in that the LED lamp (5) is fixed on the reflector bowl (3) of the lamp housing (2). A 5 W high-power LED is adopted to drive the driving power supply to control the using current of the aluminum based PCB, so that the high-light effect of the LED rear fog lamp is ensured. Radiating fins on the aluminum radiating blocks are arranged, so that a good radiating effect can be obtained.
Description
Technical field
The present invention relates to lamp for automobile, particularly a kind of Auto Rear Fog Lamp.
Background technology
Rear Fog Lamp vehicle lamp light source is in the market mainly bulb and LED. Because the design of bulb source is subject to the restriction of the reasons such as space, moulding, life-span be short; And all large in the colour temperature adjustable range of advocating environmental protection, particularly LED all over the world, be conducive to use, it has, and operating voltage is low, power consumption is little, so LED will be widely used in the use of automobile tool lamp as green light source. Described LED Rear Fog Lamp, its LED is the luminous tube with diode characteristic, it can only one direction energising. Conventionally brightness is exported and is directly proportional by LED electric current, but great power LED there will be saturated phenomenon under large electric current, and luminous efficiency can significantly decline, and even loses efficacy. Therefore the use electric current of great power LED can not exceed the rated value of its regulation. So with regard to this high-power LED, need to increase driving power, this driving power, in order to ensure the water proofing property of light fixture, is arranged on lamp interior. Described LED Rear Fog Lamp, it can produce a large amount of heat in the time of work. In the time that multiple LED are densely arranged, the gathering of heat will be even more serious. If as early as possible this heat is not shed, thing followed fuel factor will be very obvious, and this will cause chip internal heat accumulation, causes the series of problems such as light efficiency decline and shortening in service life. So in LED Rear Fog Lamp tool, the structural design of external heat sink is very crucial, it directly has influence on the heat-sinking capability of whole system.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of Auto Rear Fog Lamp, particularly a kind of vapour automobile-used LED Rear Fog Lamp tool, has good external heat sink effect.
Technical scheme of the present invention is achieved in the following ways: a kind of Auto Rear Fog Lamp, formed by lens, lamp housing, reflector, aluminum-based circuit board, LED lamp, driving power and aluminium radiating block, reflector, driving power and aluminium radiating block are screwed on lamp housing, it is characterized in that: described LED lamp is fixed on lamp housing (on reflector.
Described aluminum-based circuit board is arranged on the wiring board limited post in lamp housing, after spacing to aluminum-based circuit board left, right, front and rear, reflector be pressed in lamp housing and by cover of upholstery position-limit foot to reflector carry out upper and lower spacing after, lamp housing and lens pass through welded seal.
Structure of the present invention, employing be 1 5W great power LED, it controls aluminum-based circuit board use electric current by driving power, has ensured the high light efficiency of LED Rear Fog Lamp. Heat radiation gear piece on aluminium radiating block, can obtain better radiating effect.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Known by Fig. 1, a kind of Auto Rear Fog Lamp is characterized in that: by lens 1, lamp housing 2, reflector 3, aluminum-based circuit board 4, LED lamp 5, driving power 6 and aluminium radiating block 7 form, reflector 3, driving power 6 and aluminium radiating block 7 are screwed on lamp housing 2, and described LED lamp 5 is fixed on the reflector 3 of lamp housing 2. LED lamp 5 is a 5W great power LED, controls the use electric current of aluminum-based circuit board 4 by driving power 6. Aluminium radiating block 7 is provided with the gear piece with multiple heat radiations.
Aluminium radiating block 7 of the present invention is a hot good conductor with a lot of heat radiation gear pieces. In the time of design radiator structure, first aluminum-based circuit board 7 will have certain thickness, in order to resist the impact of transient thermal load. In the time switching on power, LED driving power drives aluminum-based circuit board 7 to keep certain current range to light, first LED is delivered on conduction estersil by aluminum-based circuit board lighting the heat producing in process, be delivered on aluminium radiating block by conduction estersil more afterwards, by the base plate on aluminium radiating block 7, the heat of generation is derived from lamp interior again, finally by the gear piece structure on aluminium radiating block 7 by dissipation of heat in air ambient.
