As explained above, the present invention divides the aluminum base plate into two parts so that the odd-numbered and even-numbered LED arrays are separated and mounted on a predetermined precision basis, so that they can be combined and separated. Since a comb-shaped aluminum base plate is used, the operating characteristics of the LED array mounted on this comb-shaped aluminum base plate can be checked before the comb-shaped aluminum base plate is connected, and defective LED chips can be replaced.
In other words, there are other LEDs on both sides of the defective LED chip.
Since the replacement work is not done with chips installed next to each other, other
It has the effect of not damaging the LED chip. Also,
Defective LED after combining comb-shaped aluminum base plate
The comb-shaped aluminum base plate can be separated even if a chip is found, so in this case, the same procedure as above should be carried out.
LED chips can be replaced.
