Abstract
A birthday candle with an automatic lighting effect mainly includes a candle body, a wick connected to the candle body with an end protruding outside an upper end of the candle body, a light sensor configured in the candle body at a position close to the wick and configured for detecting light generated by the wick when the wick burns, a light source, and a control circuit board electrically connected with the light sensor and the light source. The control circuit board is used for controlling the light source according to signals output from the light sensor. The control circuit board turns on the light source once the wick burns and turns off the light source once the wick is extinguished, such that the light source can work synchronously and coordinately along with the wick.
