DEVICE PROVIDING COORDINATED EMISSION OF LIGHT AND VOLATILE ACTIVE

摘要

A flameless candle comprises at least one LED that emits a flickering light to emulate a flame of a candle. It has a receptacle that receives one or more batteries to provide power to said at least one LED to control circuitry includes at least one of (i) a current source controller that controls a current supplied to said at least one LED and (ii) a charge pump that ensures a supply voltage to said at least one LED that exceeds a forward voltage of said at least one LED, when the voltage provided by the one or more batteries falls below the forward voltage; and a support structure that supports said at least one LED, said receptacle, and said control circuitry, said support structure including a diffuser that diffuses the flickering light emitted by said at least one LED.
