Description
Technical field
The utility model relates to a kind of led circuit plate, especially a kind of circuit board that helps the low-power LED heat radiation.
Background technology
Plurality of advantages such as LED has that volume is little, simple in structure, little power consumption, life-span long (can reach 100,000 hours), shock-resistant, anti-vibration, its principle of luminosity is solid luminescence, by the solid luminescence physics principle, the spectrum of LED almost all concentrates on visible light frequency band, and luminous efficiency is up to more than 90%.Therefore, LED is described as the 21 century new light sources, promptly it will become after incandescent lamp, fluorescent lamp, high-intensity gas discharge lamp the 4th generation light source, and be acknowledged as one of current ten big cutting edge technologies.
The LED advantage is numerous, but its shortcoming also can not be ignored, and as can producing a large amount of heats in the LED luminescence process, and the temperature resistant capability of LED itself is relatively poor, and these heats will directly have influence on the luminous mass of LED as can't effectively shedding.Therefore, heat radiation is that LED wants one of problem that emphasis solves.Its printed circuit area of traditional led circuit plate is generally less, and the area of the particularly corresponding Copper Foil that is welded with the LED pin is general also very little, and this heat that causes producing in the LED luminescence process is deposited in one and be difficult in time distribute easily.In addition, in the LED welding process, generally be that the pin with LED almost all stretches in the circuit board plate body, even the bulb of LED is close to the circuit board plate body, the more unnecessary pin length of LED in the circuit board plate body another side is cut after having welded.This way is no doubt quite right, but is unfavorable for that LED in time distributes the heat that produces, thereby causes the luminous mass of LED influenced deeply.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, a kind of circuit board that helps the low-power LED heat radiation is provided, and this circuit board that helps the low-power LED heat radiation has improved the heat-sinking capability of led circuit plate greatly by changing printed circuit area, Copper Foil area and the LED pin length on the circuit board plate body.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of circuit board that helps the low-power LED heat radiation comprises a circular circuit board plate body; Around the panel outer of this circle circuit board plate body and mid portion be distributed with many printed circuit bodies, be distributed with correspondence on the printed circuit body and be welded with the Copper Foil of LED pin, be made as than the original structure printed circuit and have more large-area printed circuit sheet corresponding to being used for connecting printed circuit body between the LED; The Copper Foil that correspondence is welded with the LED pin is made as than the original structure Copper Foil has more large-area Copper Foil piece; The pin fraction of this LED stretches in the welding hole of circular circuit board plate body, and the pin major part of this LED is stayed circular circuit board plate body outside.
The pin length of staying circular circuit board plate body outside of described LED is 1～3mm.
The pin length of staying circular circuit board plate body outside of described LED is 3mm.
Described circular circuit board plate body outer is distributed with some square breach, and the mid portion of circular circuit board plate body is provided with a manhole.
Couple together with lead between the printed circuit of position, described circular circuit board plate body outer and the printed circuit of medium position.
A kind of circuit board that helps the low-power LED heat radiation of the present utility model, design has than the original structure printed circuit and has more large-area printed circuit sheet on corresponding to the printed circuit body that is used for connecting between the LED, particularly being welded with on the Copper Foil of LED pin design in correspondence has than the original structure Copper Foil and has more large-area Copper Foil piece, the heat that the LED luminescence process is produced can be delivered on the Copper Foil piece by pin, by the Copper Foil piece heat is distributed again.In addition, the pin length outside the circular circuit board plate body of staying of LED is designed to 1～3mm or 3mm, makes it expose the certain length of circular circuit board plate body, then can enlarge the radiating surface of LED, thereby help the LED heat radiation better.
The beneficial effects of the utility model are: because design has than the original structure printed circuit and has more large-area printed circuit sheet on corresponding to the printed circuit body that is used for connecting between the LED, particularly being welded with on the Copper Foil of LED pin design in correspondence has than the original structure Copper Foil and has more large-area Copper Foil piece, make the heat that produces in the LED luminescence process to be delivered on the Copper Foil piece, by the Copper Foil piece heat is distributed again by pin; Owing to the pin length of the circular circuit board plate body of staying of LED outside is designed to 1～3mm or 3mm, makes the radiating surface of LED increase greatly, thereby improved the heat-sinking capability of led circuit plate greatly.
Below in conjunction with drawings and Examples the utility model is described in further detail; But a kind of circuit board that helps the low-power LED heat radiation of the present utility model is not limited to embodiment.
