Candle stand with audio and visual effect
US 20020119413 A1
Abstract
A candle stand detects the candlelight from a candle and provides audio and visual effect according to the detected candlelight. The candle stand has a through hole thereon and a light detector corresponding to the through hole. The light detector detects light from the candle through the through hole and triggers a controller to provide audio and visual effect.

Description
BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a candle stand, especially to a candle stand, which detects the candlelight and provides audio and visual effect according to the detected candlelight.

[0003] 2. Description of the Prior Art

[0004] The conventional candle stand is generally a fixed structure and functions only for mounting candle. Therefore, the conventional candle stand cannot provide dynamic effect for decoration.

SUMMARY OF THE INVENTION

[0005] To overcome the drawback of the conventional and provide add-on function to the candle stand, the present invention provides a candle stand, which has a light detector to detect the candlelight and provides audio and visual effect according to the detected candlelight and with the help of a controller, thus providing dynamic decoration effect.

[0006] The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:

[0009]FIG. 3 shows the circuit diagram of the first preferred embodiment of the present invention;

[0010]FIG. 4 shows sectional view of the second preferred embodiment of the present invention; and

[0011]FIG. 5 is the perspective view of the third preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] With reference now to FIG. 1, the present invention is intended to provide a candle stand with audio and visual effect. As shown in this figure, the candle stand 2 comprises a switch 35, a volume-adjusting knob 34 and an LED indication lamp 32. The topside of the candle stand 2 can be used to mount a candle.

[0013] With reference to FIG. 2, a candle 1 is placed atop the candle stand 2 and the candle stand 2 has a through hole 21 at center part thereof and corresponding to the candle 1. A light detector 31 is placed within the candle stand 2 and corresponding to the through hole 21. When the candle 1 is lighted on, the light detector 31 can detect the light emitted from the candle 1 and then triggers a controller 3. The controller then commands the LED indication lamp 32 to emit decoration light, or commands a loud speaker 33 to play musical effect. More particular, the candle 1 contains a candlewick 11 and an optical fiber 12 parallel to the candlewick 11. The candle 1 is placed atop a supportive tray 13 on the candle stand 2, and the supportive tray 13 has a hole 131 through which the bottom end of the optical fiber 12 passes. When the candlewick 11 of the candle 1 is burned, part of the candlelight is guided by the optical fiber 12 and emits from the bottom end of the optical fiber 12. The light emitted from the bottom end of the optical fiber 12 is detected by the light detector 31.

[0014] With reference now to FIG. 3, after the light detector 31 detects the light emitted from the bottom end of the optical fiber 12, the light detector 31 triggers the controller 3. The controller 3 generates a musical signal and sends the signal to the loud speaker 33 to provide audio effect and simultaneously trigger the LED indication lamp 32 to provide visual effect. The loudness of the loud speaker 33 is controlled by the volume-adjusting knob 34. The electrical power supplying to the candle stand 2 is provided from a power source 30 connected through the switch 35 to the candle stand 2.

[0015]FIG. 4 shows sectional view of the second preferred embodiment of the present invention. In this embodiment, the candle stand 2 is provided with a thermal sensor 40. The thermal sensor 40 can detect the radiated heat when the candlewick 11 of the candle 1 is burned and then triggers the controller 3. The controller 3 generates a musical signal and sends the signal to the loud speaker 33 and simultaneously trigger the LED indication lamp 32. Moreover, a thermal conductive metal rod 4 is provided parallel to the candlewick 11 of the candle 1 and the lower end of the thermal conductive metal rod 4 is in contact with the thermal sensor 40 through the hole 131 on the supportive tray 13.

[0016]FIG. 5 is the perspective view of the third preferred embodiment of the present invention. The candle stand 2 in this preferred embodiment of the present invention is of L-shape and comprises a vertical part 23 and a horizontal part 22 for placement of a candle 1. The vertical part 23 has a through hole 21 corresponding to the position of the candle 1 and a light detector 31 is placed within the through hole 21. The light detector 31 detects the light emitted from the candle 1, and then triggers the controller 3 (not shown) to activate audio and visual effect.

[0017] The light detector 31 is adapted to have detecting wavelength matching with the emitting wavelength of the candlelight, thus reducing noise from background light.

[0018] Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
