MULTI-VOLTAGE AND MULTI-BRIGHTNESS LED LIGHTING DEVICES AND METHODS OF USING SAME

摘要

A single chip multi-voltage or multi-brightness LED lighting device having at least two LED circuits having at least two LEDs connected sepes, and electrically unconnected in a parallel relationship, a forward operating dpve voltage of at least six volts and are monolithically integrated on a single substrate, configurable by means of connecting the circuits so as to provide optional operating voltage level and/or desired bnghtness level wherein the electrical connection at the LED packaging level when the single chips are integrated into the LED package Alternatively, the LED package may have external electrical contacts that match the integrated chips within Optionally allowable, the drive voltage level and/or the bnghtness level select-ability may be passed on through to the exterior of the LED package and may be selected by the LED package user, the PCB assembly facility, or the end product manufacturer.
