Abstract
The utility model discloses an LED (light-emitting diode) circuit board, which comprises an anode copper foil and a cathode copper foil covered on a baseboard, wherein the area of the cathode copper foil is more than the area of the anode copper foil. The LED circuit board has the beneficial effects that the anode and cathode copper foils are reasonably arranged on the PCB (Printed circuit board) board aiming at the characteristic that the heat productivity of the cathode pin of the LED is prominent, the LED cathode is conducted and cooled, and the cooling effect of LED circuit board is efficiently increased based on the original cost.
Description
Technical field
The utility model belongs to LED illuminating lamp cloth lamp technology, relates to a kind of led circuit plate specifically.
Background technology
LED illuminating lamp cloth lamp technology all is that LED is welded on the Copper Foil of pcb board by certain array way, organizes the LED that LED connects successively more.As everyone knows, the technical problem that hinders the LED maximum is that caloric value is big, and a lot of people adopt the mode that strengthens the Copper Foil radiating surface as reducing the LED caloric value.
And LED must generate heat and inhomogeneous, and its heat generating spot mainly is near the negative electrode pin of LED.
The shortcoming of prior art is: do not rake about the main heat generating spot of LED, just carry out the heat conduction cooling of extensive style at LED, its cooling-down effect is limited.
The utility model content
The purpose of this utility model is to provide a kind of led circuit plate, at the outstanding characteristics of the cathode tube human hair combing waste heat of LED, negative electrode on the reasonable Arrangement pcb board and anode Copper Foil are arranged, are primarily aimed at the LED negative electrode and carry out the heat conduction cooling, improve the cooling-down effect of led circuit plate.
The technical solution of the utility model is as follows: a kind of led circuit plate, to form by the anodal Copper Foil and the negative copper foil that cover on the substrate, and its key is: the area of described negative copper foil is greater than the area of anodal Copper Foil.
With the cathode weld of LED on negative copper foil, owing to effectively enlarged the area of negative copper foil, also just increased the radiating effect of LED negative electrode, fundamentally the main heat generating spot to LED dispels the heat, on the basis that does not increase cost, effectively improved the cooling-down effect of led circuit plate.
One end of described substrate is coated with an anodal Copper Foil of master, and the other end is coated with a main negative copper foil, and the area of described main negative copper foil is 2～6 times of main anodal Copper Foil area.
Be furnished with wiring Copper Foil matrix at anodal Copper Foil of described master and main negative copper foil, every block of wiring Copper Foil is the rectangle Copper Foil;
Every block of rectangle Copper Foil is furnished with positive copper foil towards a side of described main negative copper foil;
Every block of rectangle Copper Foil is furnished with cloudy Copper Foil breach towards a side of the anodal Copper Foil of described master;
The positive copper foil of described every block of rectangle Copper Foil stretches in the cloudy Copper Foil breach of its adjacent rectangle Copper Foil;
Be furnished with positive copper foil on the anodal Copper Foil of described master, this sun copper foil stretches in the cloudy Copper Foil breach of its adjacent rectangle Copper Foil;
Be furnished with cloudy Copper Foil breach on the described main negative copper foil, the positive copper foil of its adjacent rectangle Copper Foil stretches in the cloudy Copper Foil breach of described main negative copper foil.
The area of described rectangle Copper Foil is 3～6 times of positive copper foil area.
Have ventilation cooling holes array on the described substrate.
Ventilation cooling holes array can directly be realized the integral body cooling of pcb board, improves cooling-down effect.
Remarkable result: a kind of led circuit plate is provided, at the outstanding characteristics of the cathode tube human hair combing waste heat of LED, negative electrode on the reasonable Arrangement pcb board and anode Copper Foil are arranged, be primarily aimed at the LED negative electrode and carry out the heat conduction cooling, on the basis that does not increase cost, effectively improved the cooling-down effect of led circuit plate.
