Abstract
In one embodiment, an apparatus includes circuitry configured to receive a dimming input to control a dimming level of a lamp. Also, the apparatus includes circuitry configured to generate a control signal based on the dimming input. The control signal indicates the dimming level for a converter of the lamp and the converter is configured to interpret the control signal to control to the dimming level of the lamp using a sinusoidal signal.
Claims20
An apparatus comprising:
- circuitry that receives a dimming input to control a dimming level of a lamp;
- and
- circuitry that generates a control signal being a sinusoidal signal, the control signal based on the dimming input, wherein the control signal indicates the dimming level for a converter of the lamp, the converter interprets the control signal to control the dimming level of the lamp using the sinusoidal signal.
An apparatus comprising:
- circuitry that receives a control signal being a sinusoidal signal, the control signal based on a dimming input to control a dimming level of a lamp;
- circuitry that interprets the control signal to determine the dimming level for a converter of the lamp;
- and
- circuitry that controls the dimming level of the lamp by adjusting a dimming level for a load of the lamp using the sinusoidal signal.
