Abstract
The utility model relates to an LED (light-emitting diode) automobile lamp, which is mainly used for illumination of an automobile headlamp and comprises an LED lamp and a control circuit board, wherein the LED lamp is connected with the control circuit board; the control circuit board is arranged below the LED lamp; a radiator is arranged below the control circuit board; a fan is arranged below the radiator; the control circuit board is clung to the radiator; and the radiator is fixed on the fan. The radiator is arranged below the control circuit board of the LED lamp, and clung to the control circuit board, so that internal heat is introduced into the radiator very well; the fan brings the heat in the radiator out directly, so that a radiating effect is accelerated; and the defects that light failure is caused and the service life of the automobile lamp is shortened due to heat energy accumulation in a lampshade of the LED lamp are overcome.
Description
Technical field
The utility model relates to automotive field, relates in particular to a kind of LED auto lamp.
Background technology
The LED auto lamp refers to that vehicle lamp light source all adopts the LED technology, is used for throwing light on.LED's is firm in structure, is not easy affected by vibrationly, and in use procedure, the light output brightness can obviously not descend yet.The LED auto lamp is suitable for the various illuminations of automotive electronics to be used, and comprises headlight (high beam and dipped headlights), fog lamp, taillight, brake lamp, turn signal lamp, the day driving lamp, courtesy light, instrument panel lamp, license plate lamp, vehicle door lamp, room light lamp, side-marker lamp, navigation, entertainment systems, backlight and indicator lamp etc.
The advantage of LED auto lamp is:
One, energy-conservation: the LED lamp is to be directly luminous energy by electric energy conversion by light emitting diode, only is equivalent to 1/10 of conventional lights than the power consumption of general-utility car bulb, can better save oil consumption, and the protection automobile circuit is not burnt out by too high load current.
Two, environmental protection: there is no ultraviolet ray and infrared ray in spectrum, both there is no heat, also there is no radiation, dazzle is little, and discarded object is recyclable, does not pollute not contain mercury element, can safe touch, belong to typical green illumination light led source.
Three, the life-span is long: there is no loosening part in lamp body yet, do not have the easily shortcomings such as burning, heat deposition, light decay of filament light-emitting, under appropriate electric current and voltage, can reach 8-10 ten thousand hours service life, and longer more than 10 times than the conventional light source life-span.
Four, high brightness, high temperature resistant.(electric energy directly is converted to luminous energy, generates heat little, and complete available hand touches, and safety is relieved).
Five, volume is little.The meter person is conversion light fixture pattern arbitrarily, makes the vehicle configuration variation.The favor LED of automobile vendor is that the advantage of LED itself determines fully.
Six, stability is good, and the led anti-seismic performance is strong: resin-encapsulated, and not easily broken, easily store and transport.
Seven, luminance purity is high, and color is clear bright-coloured, need not lampshade and filters, and the light wave error is in 10 nanometers.
Eight, reaction speed is fast, need not the thermal starting time, can be luminous in microsecond, and traditional glass bulb bulb has delay in 0.3 second, can prevent from knocking into the back, and guarantees traffic safety.
But in the LED lamp that headlight for vehicles uses, the control circuit board of LED lamp is in long-time use procedure, produce a large amount of heat energy, and the gathering of other heats, its thermal diffusivity is bad, and radiating treatment of the prior art is only by aluminum thermal fin is set on every side, and heat dispersion is poor, be easy to cause light decay, affect the service life of car light.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and the LED auto lamp that provides.
The utility model is to realize like this, a kind of LED auto lamp, be mainly used in the headlight for vehicles illumination, comprise LED lamp and control circuit board, described LED lamp is connected with control circuit board, and control circuit board is located at the below of LED lamp, the below of described control circuit board is provided with radiator, the below of described radiator is provided with fan, described control circuit board held against heat sink, and described radiator is fixed on described fan.
Further, the direction of the light-illuminating on described LED lamp is provided with lens.
Further, the lower end of described radiator is provided with groove.
Further, described fan comprises pedestal and flabellum, and described flabellum is located on pedestal, and the upper end of pedestal is provided with the boss with described groove phase close-fitting, and described radiator and fan mutually block and fix by groove and boss.
Further, described pedestal is provided with for fixing through hole.
The advantage of the LED auto lamp that the utility model provides is: by below the control circuit board of LED lamp, radiator being set, and radiator is close to control circuit board, well internal heat is imported in radiator, directly the heat in radiator is being taken out of by fan, accelerate radiating effect, the interior heat energy of lampshade that prevents the LED lamp gathers, thereby causes light decay, reduces the service life of car light.
