Abstract
A lighting device includes a housing having a cavity and a translucent area, a plurality of discrete light emission points (DLEPs) positioned in the cavity for emitting light through the translucent area, a power source, and a controller causing the DLEPs to simulate a burning wax candle. The housing is configured to imitate a wax candle. The controller actuates a first of the DLEPs according to sequential first intensity values, and actuates a second of the DLEPs according to sequential second intensity values. The sequential first intensity values are determined by sequentially combining first change values to an initial first intensity value, and the sequential second intensity values are determined by sequentially combining second change values to an initial second intensity value. Sequential increases/decreases in the first intensity values simulate increases/decreases in optimal flame chemistry, and sequential increases/decreases in absolute value of the first change values simulates increases/decreases in turbulence.
