SMOOTH DIMMING OF SOLID STATE LIGHT SOURCE USING CALCULATED SLEW RATE

SMOOTH DIMMING OF SOLID STATE LIGHT SOURCE USING CALCULATED SLEW RATE

A method and system are provided for smoothly dimming a solid state light (SSL) source. The method includes measuring a dimming angle (S322) of a voltage received from a dimmer, determining a target brightness (S323) of light to be output by the SSL source corresponding to the dimming angle, determi...

description A method and system are provided for smoothly dimming a solid state light (SSL) source. The method includes measuring a dimming angle (S322) of a voltage received from a dimmer, determining a target brightness (S323) of light to be output by the SSL source corresponding to the dimming angle, determining a current brightness (S324) of light currently output by the SSL source, and determining a slew rate (S325) based on the current brightness and the target brightness. The current brightness of the light currently output by the SSL source is adjusted (S326) to the target brightness using the nonlinear slew rate.
