Description
Technical Field
The utility model relates to a car headlight technical field especially relates to a high-efficient radiating car headlight.
Background
Conventional LED headlight for car in the existing market, LED lamp pearl are fixed on the heat conductor, and the heat conductor conducts the heat that LED lamp pearl produced to the radiator, and radiator one end still is provided with the heat dissipation that fan and fan cover were used for the radiator to can reduce the temperature of LED lamp pearl, make the headlight can the continuous work.
In the traditional LED headlamp for the vehicle, wind generated by the fan blows over the radiator along the lamp body direction, but due to the open structure of the radiator and the radiating fins, part of wind is not completely diffused to the periphery through the radiator, and the utilization rate of air cooling is very low, so that the radiating efficiency of the radiator of the structure is low, more energy is wasted, and the heat of the LED lamp bead is directly overhigh. Therefore, the lamp beads can only reduce the power and cannot exert the maximum brightness, so that the brightness is insufficient in the driving process of the vehicle, and the safe driving of the vehicle is influenced; meanwhile, the service life of the lamp bead is shortened sharply, the lamp bead cannot reach the normal service life and is scrapped, and waste is extremely large. Therefore, it is important to invent a vehicle headlamp capable of dissipating heat efficiently.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a high-efficient radiating automobile-used headlight solves traditional automobile-used LED headlight radiator structure radiating effect not good, arouses LED lamp pearl heat too high, leads to the unable maximum brightness influence of performance of lamp pearl to drive safety to and too high temperature leads to the problem that lamp pearl life-span shortens.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a high-efficient radiating automobile-used headlight, includes the lamp body, the lamp panel on the lamp body is established to the cover, the lamp body include LED circuit board, heat conductor, lamp pearl safety cover, lamp panel, radiator, fan casing, LED circuit board laminating heat conductor, LED circuit board and heat conductor on the cover have the lamp pearl safety cover, the heat conductor connect the radiator, radiator one end be provided with the fan casing, the fan casing in be provided with the fan, the outside cover of radiator have the windshield. In order to prevent the windshield and the radiator from loosening, the windshield is fixedly connected with the radiator.
Furthermore, in order to prevent slipping during installation of the lamp body and achieve the decoration effect, a plurality of convex patterns are arranged on the outer surface of the windshield.
The utility model has the advantages that: the utility model discloses automobile-used headlight utilizes the windshield to seal the radiator, and the wind that the fan blew off can only pass through the radiator along the lamp body direction, makes all wind spread all around after passing through the radiator completely, and the radiating efficiency has accomplished the maximize, can maximize the power that promotes LED lamp pearl, has guaranteed the safety of driving a vehicle; meanwhile, the service life of the LED lamp bead is prolonged, and energy waste and material waste are effectively reduced.
The present invention will be described in more detail with reference to the accompanying drawings and examples.
Drawings
Fig. 1 is a structural diagram of a vehicular headlamp with high heat dissipation efficiency.
Fig. 2 is a sectional view and a heat dissipation diagram of a conventional headlamp heat sink.
Fig. 3 is a cross-sectional view and a heat dissipation diagram of the heat sink with a windshield according to the present invention.
Detailed Description
An embodiment, as shown in fig. 1, the vehicle headlamp with efficient heat dissipation includes a lamp body, a lamp panel 7 sleeved on the lamp body, the lamp body includes an LED circuit board 1, a heat conductor 2, a lamp bead protection cover 3, a heat sink 4, and a fan cover 5, the LED circuit board 1 is attached to the heat conductor 2, the LED circuit board 1 is connected to a power supply, the lamp bead protection cover 3 is sleeved on the LED circuit board 1 and the heat conductor 2, the heat conductor 2 is connected to the heat sink 4, and the heat sink 4 can be formed by metal extrusion, machine tool machining, metal sheet folding and the like, and includes all types of heat sinks. The fan cover is characterized in that a fan cover 5 is arranged at one end of the radiator 4, a fan is arranged in the fan cover 5, and a wind shield 6 is sleeved outside the radiator 4.
In order to prevent the windshield 6 and the radiator 4 from loosening, the windshield 6 and the radiator 4 can be fixedly connected in a screw, glue or interference fit manner.
In order to prevent slipping when the lamp body is installed, the friction force between the hand and the outer surface of the windshield 6 is increased, and meanwhile, the decoration effect is achieved, a plurality of convex grains or concave-convex stripes are arranged on the outer surface of the windshield 6, and the friction can be increased by adopting other modes such as changing the surface roughness of the windshield 6.
As shown in fig. 2, in the conventional LED headlamp for a vehicle, the heat sink and the heat dissipation fins are open structures, no obstacle is provided around the heat sink, and a considerable amount of wind is not completely diffused around the heat sink, so that the utilization rate of air cooling is low, and the heat dissipation efficiency is low.
And as shown in fig. 3, the utility model discloses because seal the radiator with the windshield, only leave an export along the lamp body direction, the wind that the fan blew off can only pass through the fin of radiator along the lamp body direction, just to spread all around after making all wind pass through the radiator completely, and the utilization ratio of wind is 100% almost, has improved the radiating efficiency greatly.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited to the above embodiments, and various modifications made by the method concept and technical solution of the present invention or those directly applied to other applications without modification fall within the protection scope of the present invention.
