## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a candle holder, and more particularly to an electronic candle holder with candle light activated illumination.
2. Description of the Related Art
Candles used to be a popular lighting tool in the past. To securely mount candles, candle holders were invented. However, after the invention of electric lamps, candles are no longer the primary lighting tool of human beings but are used to add a romantic atmosphere in collaboration with candle holders. To increase the variety of candle holders, a candle holder with candle light activated illumination is invented.
With reference to FIGS. 7 to 9, a conventional candle holder with candle light activated illumination has a base 80, a circuit board 90, a display sheet 100, a candle seat 110, and a housing 120. The base 80 is a board with a central portion rising up to form a battery chamber 81. The circuit board 90 is mounted on a top of the rising portion, and has an optical controller 91 and a lamp set 92 mounted thereon. The display sheet 100 is light-transmissive and is mounted around the base 80 to form a tubular layer. A fixing ring 101 is mounted around a periphery of the display sheet 100 and is securely mounted on the base 80. The display sheet 100 has a pattern layer 102 formed on a surface of the display sheet 100. The candle seat 110 is mounted to a top opening of the tubular layer, and only a tailor-made candle 111 can be placed in the candle seat 110 such that the candle holder with candle light activated illumination is only good for one-time operation. The so-called tailor-made candle 111 has a candle wick 112 mounted through a bottom of the candle seat 110. After a light guide strip 113 is mounted in the candle wick 112, the candle wick 112 and the light guide strip 113 are fixed by filling candle wax. An opaque shield 114 covers an exposed portion of the candle wick 112 mounted through the bottom of the candle seat 110 and the optical controller 91 on the circuit board 90 for one end of the light guide strip 113 to be adjacent to the optical controller 91. The housing takes the form of a hollow cylinder and encloses the foregoing elements therein.
With reference to FIG. 10, when users light the candle wick 112, candle light is propagated to the shield 114 through the light guide strip 113 mounted in the candle wick 112, and shines on the optical controller 91 on the circuit board 90 to light the lamp set 92. The resultant light emitted from the lamp set 92 passes through the pattern layer 102 on the display sheet 100 to exhibit a corresponding light and shadow effect to increase visual appeal. However, the circuit board 90 is damage-prone as the melting wax easily flows to the circuit board 90 through the portion of the bottom of the candle seat 110 mounted through by the candle wick 112.
SUMMARY OF THE INVENTION
An objective of the present invention is to provide a candle holder with candle light activated illumination to prevent the melting wax of the candle from flowing into the candle holder and damaging a circuit board in the candle holder.
To achieve the foregoing objective, the candle holder with candle light activated illumination has a base, a circuit board, an optical controller, and a candle seat.
The base has a battery box.
The circuit board is mounted on the base and has a driver and a light-emitting diode (LED) lamp set.
The optical controller is mounted on the base and drives the circuit board to operate after sensing candle light.
The candle seat is mounted on the base and has an opening, a light guide strip, and an inner display sheet.
The opening is formed through one end of the candle seat.
The light guide strip is inverted L-shaped and is formed inside the candle seat. One end of the light guide strip is exposed from an inner portion of the candle seat adjacent to the opening of the candle seat, and the other end of the light guide strip downwardly extends into the candle seat and has a cap mounted thereon to cover the optical controller on the fixing plate.
The inner display sheet is mounted around an outer periphery of the candle seat and the circuit board, and is transparent.
The advantage of the present invention resides in that one end of the light guide strip radially extends beyond an inner wall of the candle seat and is adjacent to a top opening of the candle seat. Accordingly, the melting wax of the candle cannot easily flow into the candle seat through the light guide strip and would not cause damage to the circuit board. Also because the light guide strip is mounted inside the candle seat, operational convenience can be enhanced since regular candles are adequate for lighting to achieve a desired optical control effect through the light guide strip without requiring the use of tailor-made candles.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The fixing wall 32 is formed on and protrudes upwards from a top of the fixing plate 30, and has a recessed edge 33 formed in a top surface of the fixing wall 32. The two positioning rods 34 are oppositely formed on an inner surface of the fixing wall 32 of the fixing plate 30.
The circuit board 40 is mounted on the fixing wall 32 with a perimetric edge abutting against the recessed edge 33 of the fixing plate 30, and has a driver 41, a light-emitting diode (LED) lamp set 42, and an electric wire 43. The electric wire 43 is electrically connected with the optical controller 31 on the fixing plate 30. When sensing light, the optical controller 31 drives the circuit board 40 to operate. The circuit board 40 further has two indentations 44 oppositely formed in the perimetric edge of the circuit board 40 to correspond to the two positioning rods 34 for the circuit board 40 to be held by the positioning rods 34.
With reference to FIGS. 1, 2 and 4, the candle seat 50 is securely mounted on the fixing plate 30 for mounting a candle 51 in the candle seat 50. The candle seat 50 has a top chamber, a bottom chamber, a bevel wall, an inner display sheet 53, and a light guide strip 54. The top chamber and the bottom chamber are separated by a partition wall, and each of the top chamber and the bottom chamber has an opening. The bevel wall is formed on the partition wall and is adjacent to the opening of the top chamber, and has a light guide hole 52 that is inverted L-shaped and is first radially formed in the bevel wall and further downwardly formed through the bevel wall. The inner display sheet 53 is mounted on an outer periphery of the candle seat 50, is transparent, and has a pattern layer formed on the inner display sheet 53. The light guide strip 54 is inverted L-shaped. One end of the light guide strip 54 radially penetrates through the light guide hole 52 on the bevel wall of the candle seat 50, and the other end of the light guide strip 54 downwardly extends into the bottom chamber and has a cap 55 mounted thereon to cover the optical controller 31 on the fixing plate 30. When the candle 51 is lit, a part of the candle light is irradiated to the bevel wall of the candle seat 50 and is further transmitted to the optical controller 31 inside the cap 55 through the light guide strip 54.
The outer display sheet 60 is tubular, is mounted on the driving assembly 20 and surrounds the driving assembly 20, the fixing plate 30, and the candle seat 50 with the candle seat 50 exposed from an opening of the outer display sheet 60. The outer display sheet 60 is rotated along with the driving assembly 20, is transparent, and has a pattern layer formed on the outer display sheet 60.
With reference to FIG. 6, the housing 70 is transparent and tubular, and has a pattern layer formed on the housing 70. The housing 70 is mounted around the base 10 and the outer display sheet 60, and has an inner thread 71 mounted on an inner bottom portion of the housing 70 and being adjacent to a bottom opening of the housing 70 to correspond to the outer thread 16 for the inner thread 71 on the housing 70 to engage the outer thread 16 on the base 10. The housing 70 further has a top opening for the candle seat 50 to be exposed from the top opening
From the foregoing, as one end of the light guide strip 54 radially extends into the candle seat 50 and is adjacent to the candle 51, the light guide strip 54 can be avoided transmitting natural light. When the wick of the candle 51 is lit, the light guide strip 54 transmits candle light to the cap 55. As the light guide hole 52 is radially formed in the bevel wall of the candle seat 50, melting wax of the candle 51 cannot easily flow into the light guide hole 52 to damage the circuit board through the light guide strip 54. Also because the light guide strip 54 is directly formed in the candle seat 50, regular candles are adequate for lighting to achieve a desired optical control effect through the light guide strip 54 without requiring the use of any tailor-made candle. Moreover, after sensing the candle light, the optical controller 31 surrounded by the cap 55 drives the driver 41 on the circuit board 40 to start operating the motor 21 and the LED lamp set 42. The motor 21 drives the driving gear 22 to rotate, the driving gear 22 drives the annular gear 25 engaging with the driving gear 22, and the annular gear 25 drives the outer display sheet 60 to rotate. The light emitted by the LED lamp set 42 generates different light and shadow effects through the inner display sheet 53 of the candle seat 50 and the outer display sheet 60 rotated along with the driving assembly 20 to enhance the visual appeal of the present invention.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
