Definitions
- one aspect of the invention provides: a universal power supply for at least one LED light engine, the power supply comprising: an input; an AC/DC converter downstream of the input; a current regulation module connected downstream of the AC/DC converter; the current regulation module acting to provide current to the LED light engine; and a current setting module in communication with the current regulation module; the current regulation module and the current setting module acting to provide constant current to an LED light engine.
- the current regulator 210 will govern the maximum possible operating current as discussed above.
- current setting module 212 is preferably employed to select a desired constant operating current up to or including the aforementioned maximum (e.g., via jumper or switch selection).
- the maximum current associated with the power supply could be configured as needed per LED specifications (e.g., at 0.300, 0.500, 0.700 or 1.00 amps).
- the power supply 200 will preferably be packaged into an enclosure for weatherproofing compliance (e.g., ANSI IP67 rating compliance).
