Abstract

One example embodiment is a photosensitive candle comprising: (a) a candle container comprising an opening; (b) a candle component disposed in the candle container, comprising: a candle body having a surface proximate to or substantially aligned with the opening; a wick with an exposed portion protruding out of the surface of the candle body; and an optical fiber embedded in the candle body and positioned juxtapose to the wick for transmitting flame lights of the wick, wherein the optical fiber comprises a first end proximate to the exposed portion of the wick and an opposing second end; (c) a lighting control component disposed in the candle container, comprising: a casing comprising an interior cavity; a controller and a power source disposed within the interior cavity; and a light sensor connected to the controller, comprising a photosensitive element proximate to the second end of the optical fiber to detect light transmitted therefrom; and (d) at least one light-emitting device connected to the controller. In some embodiments, the controller is configured to receive light signals associated with the flame lights of the wick from the light sensor, and control the at least one light-emitting device based on the received light signals.

A photosensitive candle comprising:

(a) a candle container comprising an opening;
(b) a candle component disposed in the candle container, comprising:
a candle body having a surface proximate to or substantially aligned with the opening;
a wick with an exposed portion protruding out of the surface of the candle body;
and
an optical fiber embedded in the candle body and positioned juxtapose to the wick for transmitting flame lights of the wick, wherein the optical fiber comprises a first end proximate to the exposed portion of the wick and an opposing second end;
(c) a lighting control component disposed in the candle container, comprising:
