  • Patent number: 10506679
    Abstract: The present invention belongs to the technical field of decorative lights, and discloses an LED light and an electronic candle. The LED light includes: an encapsulant body having a light condensing surface; at least two light-emitting dies packaged in the encapsulant body and spaced apart from each other, wherein, light emitted by the at least two light-emitting dies as a whole is emitted from the light condensing surface of the encapsulant body; and a dimming control circuit, outputting a varying dimming current to the at least two light-emitting dies according to dimming control signals, the dimming control signals corresponding to the at least two light-emitting dies are different, and the effect of simulated flame swing can be realized by a single LED light. The electronic candle includes the LED light, and the electronic candle has the characteristics of good simulation effect, reasonable structure setting and low production cost.
