GENERAL INSTRUCTIONS FOR WIRING OF LUXEON LEDS AND CONSTANT CURRENT POWER SUPPLIES:

WARNING: The following points MUST be adhered to

Always use a constant current LED driver

Why? – If you wire a LUXEON led to a conventional transformer or constant voltage LED driver, the LED will be destroyed. LUXEON LEDs are high power LEDs and must be run on constant current. Each LED requires supplying with a different voltage in order to be fed with a 350 mA or 700 mA constant current. For this reason they must be wired in series. 

Do not connect the power supply to the mains supply before connecting to the LED

Why? – Constant current power supplies will ‘ramp up’ to their maximum voltage in the event of an open circuit. When the LED is then connected they are being connected to a massive over-voltage. If the power supply has been connected to the mains supply with an open circuit, ensure the output terminals are short circuited to discharge the power supply internal capacitors before connecting any LEDs.

Do not switch the LED on the low voltage side of the power supply

Why? – For the same reasons as previous question.

There must be proper thermal control for the LED

Why? – The LUXEON LED is a high power LED. It has a small core where the light is produced. This core gets hot very quickly. Overheating of LED will severely shorten the life of the LED, and reduce light output. It is therefore necessary to ensure proper thermal design of all LED applications to ensure that the heat is removed from the core of the LED and dissipated elsewhere.

IMPORTANT INFORMATION:
• High power LEDs must be used in conjunction with constant current output power supply PLR, PLU, PLS, PLD or RGBox
• A maximum of 9 LEDs may be connected to one power supply (PLU/350 1-9)
• Always ensure that the temperature of the circuit board does not exceed 85oC
• When wiring High power LEDs they must be wired in series and not in parallel
