hi,
could you provide some more details, please? I've finished the circuit board and find that the power supply is 19.xxV but the voltage I need is 12V. I can't use a 78L12 coz of the large current the LED takes. So use another power supply which provide correct voltage you need with. The supply is 19V but the Vmax of LED is 12V. I have never seen a LED which is 12V-powered. Are there current-limit resistors used there in serie with LEDs? If they present then just increase their values. Regards, Oleg |
