Abstract
The utility model designs an automobile lamp structure convenient for heat dissipation of an LED lamp. The automobile lamp structure comprises an LED, other devices and a PCB (printed circuit board), and is characterized in that heat dissipation copper sheets are arranged at the LED of the PCB; the devices are forbidden to be placed in the range that the pin of the LED serve as a central point and the radius is 5mm; via heat dissipation holes are formed in the positions of pole pins of the LED; the heat dissipation copper sheets laid at positive pole pins of the LED are smaller than those laid at negative pole pins of the LED; the number of the via heat dissipation holes formed in the positive pole pins of the LED is smaller than that of the via heat dissipation holes formed in the negative pole pins of the LED; the via heat dissipation holes formed in the negative pole pins of the LED form a fan shape. The automobile lamp structure has the advantages that the temperature of the LED is greatly reduced; the heat dissipation effect of the LED is improved by more than 80 percent; the light emitting efficiency of the LED is improved; the service life of the LED is prolonged; the number of bad products is effectively decreased; the production cost is greatly reduced; the product quality is improved.
Description
Technical field
The utility model relates to a kind of car light knot of the LED of being convenient to lamp heat radiation, particularly a kind of plate level technology that is specifically designed to Super Flux LED radiating treatment.
Background technology
Existing Super Flux LED car light, does not all have well to bring in and consider LED heat dissipation problem from design.Causing a lot of products after entrucking, occur quality problems, there is " burning to death " phenomenon in a lot of LED.These find that through detecting 80% is that shorten service life because the LED that causes that " heat " causes shifts to an earlier date " aging ".In view of above situation, be badly in need of the method for the problem of finding a kind of reasonable solution Super Flux LED car light product heat.
Summary of the invention
The purpose of this utility model is to solve in prior art there is no the existing car light LED of the fine design problem of " aging " in advance in the heat radiation of LED lamp, and a kind of Vehicle lamp structure of the LED of being convenient to lamp heat radiation is provided.Can effectively solve LED product and seriously shorten because excess Temperature shifts to an earlier date " aging ", service life, affect product quality.A kind of Vehicle lamp structure of being convenient to the heat radiation of LED lamp of the utility model design, comprise LED, other device, PCB plate, it is characterized in that: the LED place on PCB plate is provided with radiating copper sheet, point centered by the Pin of LED pin, firework control device within radius 5mm scope, becomes to arrange Via louvre in the position of the utmost point pin at LED.The radiating copper sheet that lay at the anodal pin place of nearly LED is less than the negative pole pin place of LED.The Via heat radiation hole count arranging at the anodal pin place of LED is less than the Via heat radiation hole count at the negative pole pin place of LED.Via louvre at the negative pole pin place of LED becomes fan-shaped setting.The advantage of this practical new technology: significantly fallen the temperature of LED, the radiating effect of LED improves more than 80%.Improve the luminous efficiency of LED, improved the service life of LED, effectively reduced the quantity of bad product, significantly reduced production cost, and promoted product quality.
Accompanying drawing explanation
Accompanying drawing is the new schematic diagram of this practicality.
The specific embodiment
Below in conjunction with accompanying drawing, this practical heat treatment technics is described.
Figure comprises LED1, other device 3, and PCB plate, is characterized in that: the LED place on PCB plate is provided with radiating copper sheet 4, point centered by the Pin of LED pin, firework control device within radius 5mm scope, becomes to arrange Via louvre 2 in the position of the utmost point pin of LED.The radiating copper sheet that lay at the anodal pin place of nearly LED is less than the negative pole pin place of LED.The Via heat radiation hole count arranging at the anodal pin place of LED is less than the Via heat radiation hole count at the negative pole pin place of LED.Via louvre at the negative pole pin place of LED becomes fan-shaped setting.
In actual design, LED does by harassing and wrecking source and considers, avoids other thermals source harassing and wrecking LED, so other thermals source are better away from more from LED, through much experiments, finally confirms the green line scope that spacing between the two must be greater than 5mm(and sees R5 in figure).This distance is realistic in time, ideal again.As 3 position in accompanying drawing.
LED does thermal source and considers, so the heat treatment that LED must be produced is fallen, according to law of conservation of energy, this part heat can not be removed from PCB plate completely, can only derive a part of heat to air from pcb board.So increase Via hole (as 2 expressions in accompanying drawing), particular location is as figure, the position in figure draws through our a large amount of experiment.In LED "-" utmost point position, become fan-shaped placement.
PCB plate is rigidity printed substrate,
Super Flux LED is superhigh brightness LED
Via louvre is thin copper pipe communication line plate, the reverse side heat radiation by the thermal conductance in wiring board front to wiring board
Pin pin is the welding pin of LED.
