Description

The LED car light

Technical field

The utility model relates to the car light that a kind of LED of employing is the lamp source, particularly relates to a kind of LED car light that is mainly used in electric motor car.

Background technology

At present, the headlight of electric motor car adopts incandescent lamp mostly, and there is the defective of two aspects in this headlight, and the one, brightness is not enough, brings potential safety hazard to the bicyclist; The 2nd, it is excessive to consume energy, and has shortened the distance travelled of electric motor car.And the LED lamp plate is because power consumption is low, brightness is high, the life-span is long, replace incandescent lamp and become trend, as the disclosed a kind of high-power LED car light of Chinese patent patent No. ZL200820167449.7, though the car light of this structure can solve the not enough problem of incandescent lamp brightness, but must pull down the original vehicle lamp assembly of electric motor car when mounted, and sticked into one for vehicle lamp assembly, and have only its structure of destruction could install, therefore installation bothers.The heat that produces of the LED lamp of the LED car light of this structure through pallet, passes through mounting screw earlier afterwards in addition, carry out the heat conduction through the screw thread between mounting screw and the radiator again, could arrive radiator heat is distributed, because heat radiation Lu Jingchang, thermal resistance is big, can not very fast heat be distributed, because this LED car light of ground has also disposed radiator fan, accelerate heat radiation, but it is in a single day out of service because of fan failure, the early ageing of LED lamp will appear in the LED car light so, and brightness reduces, the lost of life.

The utility model content

The purpose of this utility model just provides a kind of simple installation, and heat radiation is good, and the life-span is long, the LED car light that brightness is enough.

Solution of the present utility model is such: the utility model comprises lamp house module, LED lamp plate, the radiating module that connects successively, and the endoporus of described lamp house module is through hole, and front end is the optically focused curved surface; On the described LED lamp plate LED lamp is installed, the light-emitting area of LED lamp is over against the endoporus rear end of lamp house module, and is in the focus place of optically focused curved surface; Described radiating module is close to the back side of LED lamp plate; The external diameter of described lamp house module is connected with angle, utilize angle, can be fit into easily in the electric motor car that uses the H4 bulb, perhaps the external diameter of described lamp house module is a big taper type of little tail, electric motor car reflector junction is inserted at the taper type position, just can use the utility model.

Further: the afterbody of radiating module is the heat radiation branchial plate.

The utility model compared with prior art has following beneficial effect:

1, be easy to install: the utility model can directly be installed on electronic car light reflector lamp hole place, faying face at both is coated viscose glue, after treating that viscose glue is stable, lead of the present utility model is connected to corresponding driving power, car light can normally use, need not change the structure of the original car light lampshade of electric motor car, reflector, need not to open original vehicle lamp assembly yet, quick and easy for installation.

: heat radiation is good: because LED lamp plate of the present utility model is directly to stick on the heat abstractor, the heat that LED produces is by behind its substrate, directly pass on the heat radiation branchial plate, because the heat radiation branchial plate is in the outside of car light lampshade, it is non-confined space, therefore the heat that produces of LED lamp scatters in flow air by fin enough rapidly, guarantees LED lamp operating temperature in safe range, thus the long-life of guaranteeing LED.

The specific embodiment

Embodiment of the present utility model comprises optically focused curved surface 1, angle 2, lamp house module 3, LED lamp plate 4, LED lamp plate lead 5, radiating module 6, through hole 7, through hole 8, screw 9, cavity 10, screw 11, cone 12.

Lamp house module 3 of the present utility model, LED lamp plate 4, radiating module 6 connect successively, and the endoporus of lamp house module 3 is through hole, and front end is optically focused curved surface 1; On the described LED lamp plate 4 the LED lamp is installed, the light-emitting area of LED lamp is over against the endoporus rear end of lamp house module 3, and is in the focus place of optically focused curved surface; Described radiating module 6 is close to the back side of LED lamp plate 4; The external diameter that the external diameter of described lamp house module 3 is connected with angle 2 or described lamp house module 3 is a big taper type of little tail.

Described radiating module 6 afterbodys are the heat radiation branchial plate.

As Fig. 1, Fig. 2, Fig. 3, embodiment one shown in Figure 4, the utility model is made of lamp house module 3, radiating module 6, LED lamp plate 4, LED lamp plate lead 5, screw 9, external diameter in lamp house module 3 is provided with two angles 2, and optically focused curved surface 1 is arranged on the inside of lamp house module 3 front ends.Be provided with a cavity 10 that is enough to hold LED lamp plate 4 at the afterbody of lamp house module 3, cavity 10 is communicated with optically focused curved surface 1.Afterbody in lamp house module 3 also has two for the screw 11 that is connected with radiating module 6.Between the heat-transfer area of radiating module 6 and the back side, also be provided with two through holes 7 and two through holes 8, the through hole that through hole 7 and through hole 8 are used as mechanical connection between lamp house module 3 and the radiating module 6 respectively and the wire guide that is used for passing LED lamp plate lead 5.The afterbody of radiating module 8 can distribute via radiating module 6 for heat radiation branchial plate, the heat that the LED lamp on the LED lamp plate 4 produces when work.Radiating module 6 is to adopt heat conduction good metal material to make.
