Abstract:
In a single lighting device including a large number of light-emitting elements (LEEs), the LEEs are divided into separately powered groups, and different combinations of the groups are fully energized to achieve the desired overall brightness. In some embodiments, the number of LEEs in each group has a binary relationship to the other groups. The resolution of the dimming is the brightness of the smallest group. In one example of five binary weighted groups of LEEs, 32 brightness levels can be achieved while the LEEs in the energized groups are fully ON. Thus, since there is no high frequency switching, there is substantially no power dissipation by the dimming control system, and there is limited noise or EMI created. The dimming control can be easily implemented with a logic circuit controlling a transistor switch for each group.

Claim (Index 40):
A lighting device comprising:\n multiple groups of light-emitting elements (LEEs), the groups being independently energizable, each of the groups comprising one or more LEEs, the groups configured to provide different amounts of light when energized, a first one of the groups configured to provide a minimum amount of light, each one of the remaining groups providing twice an amount of light of another one of the groups; and a controller operatively connected to the multiple groups and configured to determine a binary dimming code based on a received dimming signal, the binary dimming code having multiple bits, each of the groups of LEEs associated with exactly one bit of the dimming code, the controller further configured to energize each of the groups of LEEs when a corresponding bit of the dimming code has a predetermined bit value.
