If only two or three strings are wired in parallel then it is recommended to add resistors (e.g. 0.5R) to each string to help balance out the LED currents in each string. All strings must share a common heatsink for better current matching. 1st LED Last LED String 1 1st LED Last LED String 2 RACD60 1st LED Last LED String n A typical 1W high brightness white LED has a forward voltage of around 3.3V at its operating temperature and draws 350mA. Thus each LED actually draws about 1.15W. Similarly, 3W white LEDs have usually the same forward voltage but can be run at 700mA or more. Using the LED datasheet specification, the optimum LED arrangement and the best driver for each application can be worked out. The tables below show some examples. Other LED combinations may have different forward voltages at their recommended operating currents. 1W LEDS 24 26 28 30 33 35 35 36 39 42 42 42 45 LED Arrangement 2 Strings of 12 2 Strings of 13 4 Strings of 7 3 Strings of 10 3 Strings of 11 5 Strings of 7 7 Strings of 5 3 Strings of 12 3 Strings of 13 3 Strings of 14 7 Strings of 6 14 Strings of 3 3 Strings of 15 AC/DC Driver RACD60-700 RACD60-700 RACD60-1400 RACD60-1050 RACD60-1050 RACD60-2100 RACD60-2400 RACD60-1050 RACD60-1050 RACD60-1050 RACD60-2400 RACD60-4200 RACD60-1050 3W LEDS 12 14 18 18 LED Arrangement 12 in series 2 Strings of 7 3 Strings of 6 6 Strings of 3 High Power LEDs Cree CXA2011 Cree XM-L Lumiled Rebel Osram Dragon Bridgelux RS Helieon LED Arrangement Single Array 6 in series 13 in series 14 in series Single Array Single Module AC/DC Driver RACD60-700 RACD60-1400 RACD60-2100 RACD60-4200 AC/DC Driver RACD60-1050 RACD60-2100 RACD60-700 RACD60-1050 RACD60-2100 RACD60-1400 The product information and specifications are subject to change without prior notice.
