A kind of LED headlights

Technical field

It the utility model is related to automobile front lamp lighting area, and in particular to a kind of LED headlights.

Background technology

LED automobile lamp, refers to that in-car outer light source uses LED technology, for exterior and interior lighting.Exterior lighting equipment It is related to thermoae limit and EMC problems, while also has many complicated standards of unloading load testing.LED automobile lamp can widely use LED Auto lamp builds environment inside car, is 50,000 hours with the service life, LED's is firm in structure, it is not easy to and it is affected by vibration, used Light output brightness will not be decreased obviously in journey.LED automobile lamp is suitable for the various illumination applications of automotive electronics, including headlight (high beam and dipped headlight), fog lamp, taillight, brake lamp, turn signal lamp, day driving lamp, courtesy light, instrument panel lamp, board Illuminator, vehicle door lamp, room light lamp, side-marker lamp, navigation, entertainment systems, backlight and indicator light etc..

But since LED headlight costs are higher, many vehicles are not when dispatching from the factory using illuminations of the LED as headlight Light source, therefore there have been many headlight refill-units, by changing original halogen bulb into LED lamp bead, photograph is improved with this Obvious results fruit, reduces the burden of vehicle circuit system.Although now with xenon headlight, xenon headlight needs to excite by high voltage package It can just light, brightness rises slow while also easy in the presence of interference.

At present LED headlights after replacement often there are headlight spotlight effect be deteriorated phenomenon, although some car lights add Lens, but current LED headlight patch lamp beads are often two-sided patch, i.e., the installing plate two sides progress patch on pedestal, one As LED lamp bead light emitting angle be 120 degree, therefore can have a part of luminous dark space, there certainly exist some three face paste pieces LED lamp bead, but equally can there are illumination effect it is poor the problem of, therefore can cause luminous point without image of Buddha halogen lamp or xenon lamp that Sample is uniform.

Utility model content

Based on the above problem, it is good that the utility model aim is to provide a kind of illumination effect, and light distributes uniformly, light-gathering Good LED headlights.

In view of the above problems, provide following technical solution：A kind of LED headlights, including consolidate with headlight for vehicles Interference fit The pedestal of Dingan County's dress, is inserted with heat pipe on the pedestal, the heat pipe, which is located on its end outer post jamb of one end outside pedestal, to be set There are three mounting surfaces being uniformly arranged, one end end face that the heat pipe is equipped with mounting surface is smooth end mounting, the peace Dress face and end mounting are equipped with printed circuit, and a LED lamp bead is equipped with each mounting surface and end mounting, described LED lamp bead is electrically connected its realization that is connected in parallel to each other with printed circuit welding, and the pedestal is relative to its end of one end of heat pipe Face is equipped with heat dissipation copper mesh, is additionally provided with the pedestal for power cord to be led to printed circuit for the mistake to LED lamp bead power supply String holes.

In said structure, by setting 3 LED lamp beads in heat pipe surrounding, and one LED lamp bead is set in heat pipe end, The light emitting angle of 360 degrees omnidirection is formed it into, avoids the occurrence of dark space, while LED lamp bead is directly welded in the printing on heat pipe On circuit, overall structure can be made more compact.

The utility model is further arranged to, and heat-conducting silicone grease is filled between the LED lamp bead back side and printed circuit surface.

In said structure, heat-conducting silicone grease is filled between LED lamp bead bottom surface and printed circuit surface, LED lamp bead can be made Heat is quickly on conduction to heat pipe.

The utility model is further arranged to, and one end that the heat pipe is inserted in pedestal is interference fitted with pedestal.

In said structure, interference fit can effectively ensure that the heat conduction efficiency between heat pipe and pedestal.

The utility model is further arranged to, and the pedestal is equipped with copper mesh mounting groove relative to one end of heat pipe, described to dissipate Hot copper mesh is inserted in copper mesh mounting groove, and the heat dissipation copper mesh is located between one end in copper mesh mounting groove and copper mesh mounting groove Heat-conducting silicone grease is filled with gap, is interference fitted between the heat dissipation copper mesh and copper mesh mounting groove.

In said structure, by filling heat-conducting silicone grease between heat dissipation copper mesh and copper mesh mounting groove, it can pass well Pass heat heat spreader is gone out, copper mesh mounting groove promotees pedestal deformation after heat dissipation copper mesh is installed by gripping base both sides Copper mesh mounting groove is clamped radiating copper net and form interference fit, effectively avoid heat dissipation copper mesh from coming off.

The beneficial effects of the utility model：By setting 3 LED lamp beads in heat pipe surrounding, and one is set in heat pipe end LED lamp bead, forms it into the light emitting angle of 360 degrees omnidirection, avoids the occurrence of dark space, and illumination effect is good, and light distributes uniformly, Light-gathering is good, and heat-conducting silicone grease is filled between LED lamp bead bottom surface and printed circuit surface, and the heat of LED lamp bead can be made quickly to pass It is directed on heat pipe, by filling heat-conducting silicone grease between heat dissipation copper mesh and copper mesh mounting groove, can transmit heat well will Heat spreader is gone out.
