The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing and concrete embodiment.

The utility model provides a kind of LED car light, comprise LED light source, also comprise reflector, lens and substrate, described LED light source and described reflector are fixed on the first surface of described substrate, described lens scioptics fixed mount and described reflector are tightly connected, and described substrate, reflector and lens package surround described LED light source; The light of LED light source emission penetrates by lens through the reflector reflection.Preferably, described LED light source, reflector and lens are two.

Fig. 1 a and Fig. 1 b show the decomposition texture schematic diagram of the utility model LED car light.As shown in Fig. 1 a and Fig. 1 b, described LED car light comprises LED light source 1, reflector 2, lens 3 and substrate 5.Described LED light source 1 and described reflector 2 are fixed on the first surface of described substrate 5, and described lens 3 scioptics fixed mounts 4 are tightly connected with described reflector 2, and described substrate 5, reflector 2 and lens 3 surround described LED light source 1.When LED light source 1 work, at first its light of launching pass through the reflection of reflector 2, after carrying out reasonable disposition, then sends out via lens 3, realizes illuminating effect.Described lens 3 are preferably planoconvex spotlight.

In one embodiment of the present of invention, described LED light source 1 is to be fixed on the first surface that is fixed on again described substrate 5 on copper coin 6 afterwards.This is because described substrate generally uses aluminum alloy materials, is unsuitable for being welded and fixed of LED light source.In order to fix LED light source more firm, after can being welded on described LED light source 1 on copper coin 6, copper coin be arranged on the first surface of described substrate 5.Be understandable that, also can make LED light source need not copper coin and directly be fixed on described substrate by other any means, for example copper coin is used as substrate, LED light source directly can be weldingly fixed on described substrate.

Fig. 2 is the structural representation of reflector in embodiment of the utility model.As shown in Figure 2, described reflector comprises reflecting surface.Preferably, the reflecting surface of described reflector is comprised of a plurality of miniature free form surfaces.Described LED light source 1 is surrounded by reflector 2, substrate 5 and lens 3, and described LED light source 1 can be placed in any position of described substrate 5, as long as the light of light source emission can be entered lens by the reflector reflection.For example, described LED light source 1 can be placed in any one focus place that is arranged in described a plurality of miniature free form surfaces on described substrate.The reflecting surface that has the free form surface composition of a plurality of combinations due to reflector, the light of LED light source emission can strengthen the light intensity that reflects reflector thus through a plurality of free form surfaces reflections, has improved the light source utilization rate.

Described reflecting surface can also be that 1/4th spherical or elliposoidals or class are spherical, can be also other any shapes, enters lens as long as reflecting surface can reflect away with the light that allows LED light source 1 launch coordinating of LED light source 1.When this reflecting surface is 1/4th when spherical, light source 1 can be arranged at this spherical centre of sphere place.Again for example, when this reflecting surface is elliposoidal, this light source 1 can be arranged at a focus place of this elliposoidal, thereby utilizing emitted light is directional light.It will be appreciated by persons skilled in the art that this reflecting surface can be other any suitable shape, the class that for example has complicated shape is spherical, thereby forms required reflecting effect.

In an embodiment of the present utility model, the first groups of fins is installed on second of described substrate; Be provided with heat pipe in described substrate and the first groups of fins, described heat pipe passes described substrate and the first groups of fins; Described heat pipe is U-shaped, and the one end passes described substrate, and after the U-shaped bend, the other end passes described the first groups of fins; Described heat pipe process substrate is positioned at the position under LED light source; Also be provided with the second groups of fins on the first surface of described substrate.

Fig. 3 and Fig. 4 show respectively the combining structure schematic diagram of LED light source, substrate and fin in embodiment of the utility model and along the axial cutaway view of A-A.As shown in Fig. 3 and Fig. 4, the first groups of fins 7 is installed on second of described substrate 5, the dissipation of heat that produces when being used for LED light source is worked is gone out.Be provided with heat pipe 8 in 7 groups of described substrate 5 and the first fin, described heat pipe 8 passes described substrate 5 and the first groups of fins 7.Preferably, described heat pipe 8 is U-shaped, and the one end passes described substrate 5, and after the U-shaped bend, the other end passes described the first groups of fins 7.More preferably, described heat pipe 8 is positioned at position under LED light source 1 through substrates 5.Owing to having adopted heat pipe, and heat pipe is through under LED light source, when LED light source is worked, the heat of its generation can be conducted to rapidly the first groups of fins by heat pipe, fin evenly distributes heat, thereby reduces the operating temperature of LED light source, extends its service life.

As shown in Fig. 3 and Fig. 4, the second groups of fins 9 is installed also on the first surface of described substrate 5.At this moment, be distributed with two groups of fin on substrate 5, make the rapider of dissipation of heat, greatly improved heat-sinking capability.

In an embodiment of the present utility model, be provided with the breach that can allow the part fin of the first groups of fins expose on described substrate.As shown in Figure 3, be provided with the breach 10 that can allow the part fin of the first groups of fins 7 expose on described substrate 5.Because the part fin of the first groups of fins 7 is out exposed, make the contact area of fin and air become large, therefore area of dissipation also enlarges, thereby has improved radiating efficiency.The shape of described breach can be any shape, as long as it can make the contact area of fin and air become large.Preferably, the bottom shape of the shape of that a part of substrate of being fixedly connected with of described breach 10 1 sides and described reflector and reflector is consistent.This kind mode had not only guaranteed that reflector can be fixed on substrate but also to make breach go out the fin area that rosy clouds go out maximum, thereby farthest improved radiating efficiency.

LED car light of the present utility model can also comprise protecting the housing of lens.As shown in Fig. 1 a and Fig. 1 b, described LED car light also comprises housing 11, and it is connected with lens fixed mount 4, and lens 3 are surrounded, and lens are formed protection.

Preferably, LED car light of the present utility model is provided with baffle plate in described LED light source the place ahead, and described baffle plate is arranged on the 3rd of described substrate.Fig. 5 shows the combination schematic diagram of baffle plate, substrate and reflector in embodiment of the utility model.As shown in Figure 5, LED car light of the present utility model also comprises baffle plate 12, and baffle plate 12 is arranged on the 3rd of described substrate 5, is positioned at the place ahead of LED light source 1.When using this LED car light, when especially using as dipped headlights, the light of LED light source 1 emission is through reflector 2 reflections, the unnecessary veiling glare that baffle plate 12 will reflect sponges, form "cut-off"line clearly, thereby in the time of can effectively preventing meeting, headlamp causes dazzlingly to the other side, improves traffic safety.

The lighting demand of the applicable all kinds car class of the utility model LED car light is particularly useful for the distance-light illumination of car headlamp.When being applied to car headlamp, housing can also be designed to different patterns, realize the illuminating effects such as angel's eye, flake, lamp eyebrow, promote the class of headlamp.
