Protective effect, while certain cooling effect can be played, such as by 1 surface of shell fitting copper base, and shell is set
Into Heat Conduction Material, so that a heat part for copper base 1 is distributed by shell.
Shell is to prevent the radiator 4 of high temperature from directly being connect with neighbouring plastic cement base part in the effect of 4 peripheral part of radiator
Touch cause plastics components aging even damage, so as to reduce the failure of LED car lamp and increase LED car lamp use the longevity
Life.
Shell is with being provided with the first structure for propagating light on 3 corresponding position of LED luminescence chips.
There are many forms for first structure, can be the form of opening or the film of permission spread fiber.
Shell is with being provided with the first opening 6 for heat dissipation on 4 corresponding position of radiator.
In order to which radiator 4 is prevented to be in direct contact with other plastic cement base parts, at the same again in order to ensure the heat dissipation of radiator 4 imitate
Rate, the first opening 6 of casing part setting in 4 periphery of radiator.
The quantity of first opening 6 can be two, be separately positioned on the outside of two radiating surfaces of radiator 4.
The shape of first opening 6 is not construed as limiting, can be round or rectangular, in order to increase radiating efficiency, can be incited somebody to action
First opening 6 is shaped to coordinates contoured with radiator 4, make the radiating surface of radiator 4 as much as possible directly with outside
Air contacts.
Further,
Heat conducting pipe 2 is heat conducting pipe, and compared to the heat conducting pipe 2 of traditional aluminium, faster, light decay is low for heat conducting pipe heat conduction, and light efficiency is more
It is high more stable.
Further,
Copper base 1 is bonded by complete tin cream welding technique structure with heat conducting pipe, and heat conductive silica gel or heat conduction are used with existing
Silicone grease filling bonding heat conducting pipe is compared with copper base 1, can snugly more securely not shifted, keep the stability of light light type,
Improve heat transfer efficiency；And typical thermal-conductive silicone grease silica gel thermal conductivity factor is 0.8-4w/m.k, conventional tin cream welding thermal conductivity factor 50-
80w/m.k, so the utility model is bonded with heat conducting pipe and can largely be improved by complete tin cream welding technique structure
From to heat conducting pipe the heat transfer efficiency of copper base 1.
Referring to Fig. 5, a kind of installation signal of the LED luminescence chips 3 for LED car lamp that the utility model embodiment provides
Figure；
In the present embodiment, it is flat by heat conducting pipe, and two apparent surfaces are upper symmetrical fixed in order to simulate vehicle halogen lamp
There is copper base 1, two LED luminescence chips 3 being fixed on copper base 1 are also symmetrical, than high by LED luminescence chips 3
Size and the scale error of vehicle rule halogen lamp are controlled within 5%.
Further,
As shown in Figure 1, for more preferable simulation vehicle halogen lamp, first structure is the second opening 7, and low at the second opening 7
Case surface in the second 7 both sides of opening.
From figure 1 it appears that shell be designed as declining in opening it is step-like so that the light that LED luminescence chips 3 are sent out
It is not blocked, can preferably distribute by shell；So that both sides shine, light carpenters square cun is only two copper bases 1 for such design
With the overall thickness of heat conducting pipe, become larger when will not because shell block.
Referring to Fig. 3, the structure diagram at a kind of LED car lamp radiator 4 that the utility model embodiment provides；
LED car lamp further includes the radiator fan 10 for being arranged on 4 side of radiator.
Radiator fan 10 can be connect by screw 11 with radiator 4, and the presence of radiator fan 10 causes the utility model
LED car lamp can be radiated by passively radiating with active heat removal two ways, improve radiating efficiency.
Further,
Shell includes being distributed in the first main body 51 and the second main body 52 of heat conducting pipe both sides；
First main body 51 is connected with the second main body 52 by fixation kit.
Referring to Fig. 4, the structure diagram at a kind of LED car lamp limiting locking cap 8 that the utility model embodiment provides；
Fixation kit include limiting locking cap 8, limiting locking cap 8 be socketed in the first main body 51 and the second main body 52 composition
Outer casing end.
As shown in Figure 1 and Figure 4, in order to make limiting locking cap 8 more secured in combination with shell, the first main body 51 and the second master
It is respectively arranged on body 52 with limiting the ordinatedly sunk structure of locking cap 8.
The utility model embodiment replaces screw 11 to connect the first main body 51 and the second main body 52 using limiting locking cap 8,
Due to limiting locking cap 8 will not can be occupied as screw 11 between first main body 51 and the second main body 52 inner space, this shown reality
The ratio that can make LED car lamp of new embodiment is relatively thin, and size is smaller, facilitates installation.
Referring to Fig. 2, a kind of partial enlargement of the annular lamp base 9 for LED car lamp that the utility model embodiment provides shows
It is intended to；
In the utility model with providing a kind of LED car lamp another embodiment, fixation kit can also include socket
In the annular lamp base 9 of case surface, annular lamp base 9 can be with the clamping adjustable angle of shell.
Annular lamp base 9 is other than fixing shell, also by being assembled to install LED car lamp with other component, so
In practical applications, annular lamp base 9 is that immovably, shell and annular 9 ground of lamp base clamping pedestal 9 are adjustable so that
LED car lamp light emitting angle can adjust, effectively coordinated car light have reflector difference reflecting angle adjustment so that irradiation
Light type and light efficiency higher are more accurate.
As shown in Fig. 2, case surface is provided with protrusion 13, annular 9 inner ring of lamp base is provided with gear 14, so protrusion 13
It can be stuck in the different intervals of gear 14, accordingly, the light emitting angle of LED car lamp is just different.And the quantity of gear 14 is got over
More, the light emitting angle of LED car lamp can adjust more accurate.
As shown in Figure 1, it is additionally provided with flexible positioning between annular lamp base 9 and radiator 4 partly shell
Rubber ring 12, when firmly pinning annular lamp base 9 downwards, positioning rubber circle 12 is extruded, at this time the tooth of 9 inner ring of annular lamp base
Wheel 14 and the protrusion 13 of case surface in the same plane, can not realize the relative rotation of annular lamp base 9 and shell, when turn
When moving predeterminated position, unclamp hand, at this time annular lamp base 9 can be returned under the action of the restoring force of positioning rubber circle 12 with outside
The position of shell clamping, so as to which gear 14, protrusion 13 and the cooperation of positioning rubber circle 12 realize that annular lamp base 9 is clamped angle with shell
Degree can adjust.
The above-mentioned one way in which for only realizing annular lamp base 9 and shell clamping adjustable angle, also there are other
Various ways, no further details here.
Further, the first opening 6 is arranged on shell side, and radiator fan 10 is to 6 blowing of the first opening, with existing bottom
Portion's air-out mode is compared, and will not be blocked air inlet because of the waterproof cover of bottom, is conducive to air circulation and take away heat.
More than, above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to before
Embodiment is stated the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be with
It modifies to the technical solution recorded in foregoing embodiments or equivalent replacement is carried out to which part technical characteristic；And
These modifications are replaced, the spirit for various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
And range.
