Abstract
The utility model discloses an LED automobile headlamp. The LED automobile headlamp comprises an LED lamp arranged on an automobile headlamp base, the LED lamp is provided with a printed circuit board which is connected with the lamp base in a bonded mode through heat conduction glue, the lamp base is connected with one end of a heat conduction tube, a heat absorbing block is arranged at the other end of the heat conduction tube, cooling fins are arranged on the heat absorbing block, and cooling fans are arranged on the cooling fins. The LED automobile headlamp has the advantages of being good in cooling effect, capable of saving electricity, high in luminance, resistant to vibration, long in service life, and free of high-voltage electricity and hidden safety danger, and emitting light through solids, and therefore the LED automobile headlamp can be matched with lamp shells of all automobile types in the market.
Description
Technical field
The utility model relates to a kind of car headlamp, and specifically a kind of LED car headlamp belongs to the car headlamp field.
Background technology
LED (Light Emitting Diode), light emitting diode, be a kind of can be the solid-state semiconductor devices of visible light with electric energy conversion, it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is negative pole, and the other end connects the positive pole of power supply, makes whole wafer by epoxy encapsulation.Semiconductor wafer is comprised of two parts, and a part is P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer by wire, electronics will be pushed to the P district by 1, and then electronics will send energy with the form of photon, the luminous principle of LED lamp that Here it is with hole-recombination in the P district.And the light wavelength color of light namely is to be determined by the material that forms the P-N knot.Yet, at present, because the design of LED lamp radiator structure is complicated, can't do the reasons such as water proof and dust proof design, the LED lamp all is used in the low power ranges such as automotive interior, taillight, not yet is used on the car headlamp and uses.
The utility model content
In order to address the above problem, the utility model has designed a kind of LED car headlamp, and LED is applied to car headlamp, has solved high-powered LED lamp heat radiation and water proof and dust proof problem, economize on electricity, and brightness is high, long service life.
The technical solution of the utility model is:
A kind of LED car headlamp, comprise the LED lamp that is arranged on the vehicle front lighting lamp socket, described lamp socket links to each other with an end of heat pipe, the other end of described heat pipe is provided with heat-absorbing block, described heat-absorbing block is metal derby, for example aluminium block, copper billet, described heat-absorbing block is provided with fin, and described fin is provided with heat emission fan.
Further, described LED lamp is provided with printed circuit board, and described printed circuit board and described lamp socket are bonding by heat-conducting glue.
Further, described LED lamp and lamp socket are arranged in the lamp housing of sealing.
Further, described heat pipe is the copper heat pipe.
The temperature of LED lamp passes to copper printed circuit board (PCB), and PCB and copper lamp socket are bonding with heat-conducting glue, and heat passes to rapidly on the heat pipe, is arranged on the heat-absorbing block heat absorption of heat pipe other end, and the heat of heat-absorbing block blows away by fin and fan.Lamp socket is connected heat pipe with radiator portion and connects, and lamp socket is in lamp housing, and radiator portion is outside lamp housing, and the centre seals lamp housing with encapsulant, has solved the water proof and dust proof problem.
The utility model has the advantage of: LED is applied to car headlamp, high-powered LED lamp heat radiation and water proof and dust proof problem have been solved, radiating efficiency is high, economize on electricity, and brightness is high, solid luminescence, anti-vibration, long service life does not have high-tension electricity, there is not potential safety hazard, can be supporting with the lamp housing of all vehicles on the market.
The utility model is described in further detail below in conjunction with drawings and Examples.
