  • 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.

  • Patent number: 10184628
    Abstract: An electronic candle with electromagnetic drive unit includes a casing, a wick assembly, a light source module, an electromagnetic drive unit, and a driving circuit. The casing has a top provided with an opening having a support, and the support is provided with an aperture. The wick assembly includes a wick element having a wick plate and a counterweight element which has a counterweight block. The counterweight block is combined with a magnet. The wick assembly swings freely by being supported by the support. The light source module projects light to the wick plate. The electromagnetic drive unit drives the magnet. The driving circuit electrically controls the light source module and the electromagnetic driving unit.

  • Patent number: 9322524
    Abstract: An electronic candle includes a casing, a wick assembly, and a light source module. The casing has a top provided with an opening, the opening has an end internally provided with a support, and the support is provided with an aperture. The wick assembly includes a wick element having a wick plate and a counterweight element having a counterweight block. The wick plate has an end provided with a first connecting rod. The counterweight block has an end provided with a second connecting rod. The first connecting rod extends through the aperture and is connected with the second connecting rod in order for the wick assembly to swing freely while supported by the support. The light source module is provided in an interior of an opposite end of the opening and which is composed of at least three LEDs so arranged as to project light to the wick plate.
