Abstract
Disclosed is an illumination controller for use with at least one LED module. The illumination controller includes an input, a control output, and a processor. The command input receives at least one illumination control packet. The control output pulse modulates a signal that powers an illumination level. The processor controls the control output in accordance with an illumination level parameter associated with a first illumination control packet received at the input and a scaling parameter associated with a second illumination control packet received at the input.
Claims30
An illumination controller for use with at least one three-color LED module, comprising:
- an input for receiving at least one illumination control packet;
- a first color control output for pulse modulating a first signal that powers a first illumination level for a first color;
- a second color control output for pulse modulating a second signal that powers a second illumination level for a second color;
- a third color control output for pulse modulating a third signal that powers a third illumination level for a third color;
- and
- a processor that controls the first color control output in accordance with a first color level parameter associated with a first illumination control packet received at the input and a scaling parameter associated with a second illumination control packet received at the input, controls the second color control output in accordance with a second color level parameter associated with the first illumination control packet and the scaling parameter;
- and controls the third color control output in accordance with the third color level parameter associated with the first illumination control packet and the scaling parameter.
