Photo-controlled electronic music candle

Abstract

An interchangeable photo-controlled electronic music candle that reliably plays the music includes candle containing fusible optical fiber wick, fusible optical fiber, base, photosensitive device, a condensing chip above the photosensitive device with the optical fiber disposed at where in relation to the condensing chip; the photosensitive device receives any light source within the radius of the condensing chip to increase sensitization area to reduce consumption of photo energy; and the optical fiber is not necessarily to aim at the photosensitive device for playing the music to reduce production cost while maintaining good performance in repeated use.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The present invention is related to a photo-controlled electronic music candle, and more particularly, to one that is with its components interchangeable. [0003] (b) Description of the Prior Art [0004] As taught in U.S. Pat. No. 5,921,767, a photo-controlled electronic music candle providing a good companion for leisure and entertainment is comprised of candle, wick containing fusible optical fiber wick, music candle base, and photosensitive device. Wherein, the photosensitive device functions as the control switch to play the music. The switch is closed when subject to light and disconnected when not subject to light or to weak light. Once the candle is lighted, the candlelight passes through the optical fiber in the wick to the photosensitive device in the base of the photo-controlled to start playing the music. Upon the candle is consumed, the residual ashes on the wick completely cover up the optical fiber to b...

Benefits of technology

[0007] The primary purpose of the present invention is to provide an interchangeable photo-controlled electronic music candle that allows reliable playing of the music and repeated use.

[0008] Another purpose of the present invention is to provide an interchangeable photo-controlled electronic music candle with improved use safety, extended service life and convenient repeated use.

[0009] To achieve the purposes, the present invention is essentially comprised of a candle, a wick containing fusible optical fiver, a fusible optical fiber, a music candle base, a photosensitive device, and a condensing chip. Wherein, the condensing chip is disposed on the upper surface of the base at where above the photosensitive device. The fusible optical fiber is in alignment with the condensing chip. Only the fusible fiber is exposed out of the lower surface of the candle in alignment with the condensing chip. A fireproof shade is provided to the base and the fusible fiber penetrating a through hole on the fireproof shade to be in alignment with the condensing chip. The fusible optical fiber is tightly tied in with the through hole on the fireproof shade. The peripheral of the through hole of the fireproof shade is raised. The condensing chip is provided on the fireproof shade. An opening is provided on the upper surface of the base; a source contact switch is disposed in the base with the contact point penetrating the opening and exposed on the upper surface of the base. The condensing chip provided over the photosensitive device receives any light source emitted within the radius of the condensing chip to increase the sensitization area and reduce consumption of optical energy. Accordingly, the wick containing the fusible optical fiber is not necessarily to precisely aim at the photosensitive device to play the music thus to reduce the production cost and allow repeated use while maintaining good performance of the music candle.

[0010] Whereas the fusible fiber is the only element that is exposed out of the lower surface of the candle in alignment with the condensing chip, and the lower end of the wick is cleared away from the condensing chip for a certain distance, the flame will not contact the condensing chip when the wick is consumed. Therefore, the fusible optical fiber becomes noninflammable. No contact of the flame with the condensing chip guarantees the safety of the condensing chip, the photosensitive device and the base.

[0011] The fireproof shade provided at the bottom of the candle keeps the melting wax from flowing into the candle base to destroy the circuit in the base, and even from causing the fire alarm. Furthermore, the melting wax will not cover up the surface of the photosensitive device to allow convenient repeated use of the music candle.

[0012] With the presence of the touch switch, the circuit is disconnected from the source when there is no candle placed on the candle base to prevent the music from playing when subject to stronger light. Once the candle is in place, the circuit is connected as the switch is closed to guarantee that the music plays when the candle is lighted. Whenever the candle is moved away from the base, the circuit is cut off immediately. Accordingly, further assurance of playing the music is guaranteed.

Problems solved by technology

No contact of the flame with the condensing chip guarantees the safety of the condensing chip, the photosensitive device and the base.
