#88795 - "spider" LEDs are cool Responding to: ???'s previous message |
At least for the "spider" LEDs that I intend to use, it'll be somewhat conservative to think about overheating. They have four metal leads and each two leads are connected to each other through the LED body: a perfect heat transfer to the PCB tracks on the board. 32 x 32 LEDs plus the one layer PCB constitutes a nice 40cm x 40cm home made dotmatrix. |
