hi all
currently im building a circuit using series connected leds on aluminium pcb board. for that purpose i have some questions about leds.
on my circuit i will use 18v smd 2835 led chips. max amouth of current on each led will not exceed 27,27mA. on so on i need at least 0.5w led chips. But what if i solder 1W 18V led instead of 0.5W 18V led's ??
As wattage increased it must be much more long life but what happens when 27,27mA of current flows through 1W leds ? Will brighness decrease ? Or when i dimm the current less then from 27mA , what will happens on 1W led.
As you can see i have so much miss understoods about leds wattages , please explain more details.
Thanks
