Specific embodiment
In order to further explain the technical solution of the present invention, being explained in detail below by specific embodiment the present invention
It states.
As shown in Figure 1, a kind of small array LED lamp group circuit board of the present invention, including U-shaped circuit band 10, the U
Shape circuit band 10 is made of the first straight-arm 11, linking arm 12 and the second straight-arm 13.
First straight-arm 11 and the second straight-arm 13 are respectively formed on several for the welding position 20 of LED wafer welding, often
A welding position 20 is made of positive terminal 21, negative pole end 22 and isolation channel 23.
In being reversed, the U-shaped circuit band 10 powers on welding position 20 on first straight-arm 11 and the second straight-arm 13
Stream successively passes through each on each welding position 20 on the first straight-arm 11, linking arm 12 and the second straight-arm 13 from the end of the first straight-arm 11
