بررسی پنل بزرگ 200 وات COB LED

If I thought the COB LED panel was big the last time, then this is now officially the biggest I've ever seen. It's based on a solid panel of aluminium with a PCB layer laminated on. The COB aspect (Chips On Board) indicates the way the bare LED chips are bonded directly to the PCB layer and bond wires attached between the chip contacts and the PCB. The board has a dam of silicone piped round the desired outline and is then flooded with a layer of phosphor loaded silicone gel to protect the LEDs
