DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1, there is seen a transparent or semi-transparent container body 1 that is made in various shape. The container body 1 is fully or partially filled with wax candle 2 having a wick 21. A luminescent module 3, placed at the bottom of the wax candle 2 and on the base 6, includes a power source 31, a control module 32 connected to the power source 31, a photosensitive circuit and one or a plurality of LEDs (Light Emitting Diode) 34. A photosensitive component in the photosensitive circuit is a photosensitive resistance R2 housed in a darkroom 33 shielding light around to avoid being affected by unexpected light. The photosensitive resistance R2, the darkroom 33 and the LEDs 34 are placed on the upper surface of the base 6. As shown in FIG. 4, an alternative embodiment includes the photosensitive resistance R2, the darkroom and the LEDs 34 placed in the base 6 that can be made of transparent materials. A light-guide fiber 4, placed along the wick 21, has one entrance end thereof arranged close to the part of the wick 21 and sticking out the wax candle and the exit end thereof 41 touching the upper surface of the photosensitive resistance R2 to allow the photosensitive resistance R2 to sense the light from the wax candle.

The top surface 22 of the wax candle 2 is arranged lower than the opening surface 11 of the container body 1 to define a space in the container body 1 for burning wick 21, which allows the wick flame to burn stably therein, therefore makes the LEDs 34 illuminate stably, and also prevent the flame from reaching other articles.

Referring to FIG. 2, it shows a circuit diagram of the luminescent module 3. The photosensitive circuit includes the photosensitive resistance R2 and a first resistance R1 which are serially connected between an anode B+ and a cathode B− of the power source 31. The photosensitive resistance R2 can be a positive photosensitive resistance or a negative photosensitive resistance. The connection between the photosensitive resistance R2 and the power source 31 is random. The photosensitive resistance R2 can be connected to a cathode B− or an anode B+ of the power source 31. The serial node between the photosensitive resistance R2 and the first resistance R1 is connected to the input of the control module 32. The anode of each LED 34 is connected to the output of the control module 32. The cathode of each LED 34 is connected to the cathode B− of the power source 31.

The power source 31 is preferred to be a button battery. The control module 32 is an integrated circuit or a chip with embedded software.

When the wick 21 is burnt, candle light is transmitted via the light-guide fiber 4 to the photosensitive resistance R2. Where the photosensitive resistance R2 is positive, its resistance will go up with the increase of light intensity. Simultaneously the photo-voltage generated in the control module 32 will also go up. The control module 32 compares the generated photo-voltage with a pre-stored valve voltage. If the generated photo-voltage is higher than the pre-stored valve voltage, the control module 32 output a high tension signal to activates the LEDs 34 for luminescence.

The anode of each LED may be connected to the anode B+ of the power source 31 and the cathode of each LED 34 is connected to the output of the control module 32. Just same with the above, the LEDs 34 is activated for luminescence by the control module 32.

Referring to FIG. 3, a cap 5 is adapted to fit over the opening 11 of the container body 1 and has an opening at the top thereof to admit air. The cap 5 can be made in various shapes to shield airflow, have candle burning safe and make a decoration.

When the cap 5 is adapted over the container body 1, the top surface of the wax candle can be arranged higher than or aligned with the opening 11 of the container body.

Referring to FIG. 4, the wax candle 2 is divided as a layer 23 close to the luminescent module and a layer 24 far away from the luminescent module. In this embodiment, the layer 23 has a higher melting point than the layer 24 to prevent the layer 23 from burning. After the layer 24 is burned out, the flame of the wax candle will be out to avoid heating the luminescent module 3 and causing smoke or even fire hazards.

In order to avoid influences from environmental light, the photosensitive resistance shall be housed in a darkroom. Where the top surface of the photosensitive resistance is not sealed, the darkroom cannot function well. Where top surface of the photosensitive resistance is sealed, a hole shall be defined to allow the light-guide fiber to attach to the top surface of the photosensitive resistance. Therefore, environmental light still can pass through the hole to impact the photosensitive resistance. Referring to FIG. 4, a resilient cushion 35 can be used on the top surface of the photosensitive resistance to seal the photosensitive resistance with the darkroom and the base so as to avoid influence of environmental light. The resilient cushion 35 is of certain thickness and has a hole to allow the light-guide fiber 4 to be passed through. Since this resilient cushion is elastic, the light-guide fiber can be clamped tightly by it to prevent the environmental light from getting through and also to fix the position of the light-guide fiber so that it is helpful for the wax candle to be filled in the container body. The preferred embodiment for this resilient cushion could apply to sponge, rubber or other elastic materials.

It is provided one or more LEDs producing one or more colors. The preferred embodiment is to provide three LEDs placed on the luminescent module in an equilateral triangle configuration and respectively producing the color of red, green and blue. Under the control of the control module, the three LEDs produce in turn light, intensity of which varies from weak to strong and then from strong to weak. When the light of the first LED becomes weak, the second LED is activated and produces a light varying from weak to strong. When the light of the second LED becomes weak, the third LED is activated and produces the light varying form weak to strong. This circulates among the three LEDs. In accordance with the color mixing principle, the wax candle will illuminates variable and colorful lights promoting a pleasant sociable environment.

Although the present invention has been described with reference to preference to specific embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention as defined by the appended claims.
