hello,
building a nightvision IR LED module..
(6 IR LED + 47 ohm serial ) x 8 Row.
in the datasheet of IR LED, the continuous LED current is max 50mA.
i set the resistors to flow 35mA current in each LED. but the board heats with resistors(1/2 watts) and LEDs.
is it normal or harmful ?
do i have to increase the LEDS numbers and decrease the current to ~25 mA.
thanks.
