Abstract

The present invention relates to a candle which includes a base unit and a candle body which is mounted to the base unit. The candle body includes a wick and a fibre optic running therethrough. The base unit includes a light sensor configured to detect light from the wick, when lit. There is additionally provided a light source configured to operate in dependence on detection of light by the light sensor.

First claim

The invention claimed is:

1. A candle, comprising:
a base unit and a candle body removably mounted to the base unit;
wherein the candle body comprises a wick and a fibre optic running therethrough; and,
the base unit comprises: a light sensor configured, in use, to detect light emitted from the wick and transmitted via the fibre optic; and,
a light source configured to operate in dependence on detection of light by the light sensor: sensor; and,
a proximity sensor configured, in use, to detect the presence of a candle body mounted to the base unit, wherein the proximity sensor is operable, in use, to: output a control signal for disabling operation of the light source in dependence on the absence of a candle body mounted to the base unit and/or output a control signal for enabling operation of the light source in dependence on the presence of a candle body mounted to the base unit.

2. The candle of claim 1 , wherein the candle body comprises a recess in a portion thereof.

3. The candle of claim 2 , wherein the recess is provided in a lower portion of the candle body and is configured to receive at least a portion of the base unit for removably mounting the candle body to the base unit, in use.

4. The candle of claim 2 , wherein the base unit comprises a raised upper portion configured to be received within the recess provided within the candle body.

5. The candle of claim 1 , wherein the light source comprises one or more light emitting members.

6. The candle of claim 1 , wherein the light sensor is operable to output a signal indicative of: the presence or absence of light incident on
and/or a level of light incident on the sensor.

7. The candle of claim 6 , wherein the light sensor is operable to output a control signal for enabling or disabling operation of the light source in dependence on the presence, absence and/or level of light incident on the light sensor.

8. The candle of claim 1 , wherein the fibre optic runs substantially parallel to the wick along the length of the candle body and/or the fibre optic is exposed at an end thereof, the exposed end being positioned proximal to the light sensor of the base unit, in use.

9. The candle of claim 1 , wherein the proximity sensor is configured, in use, to identify the candle body mounted to the base unit; and to control operation of the light source in dependence on the identified candle body type.

10. The candle of claim 9 , wherein the base unit is configured to adjust the intensity and/or colour of light emitted from the light source in dependence on the identified candle body type.

11. The candle of claim 1 , wherein the candle body comprises a recess in a portion thereof, and,
further wherein the proximity sensor is configured to detect a depth of the recess within the candle body, the depth of the recess within the candle body being indicative of the size or type of the candle or type of candle mounted to the base unit.

12. The candle of claim 1 , wherein the proximity sensor is configured, in use, to identify a rotational position of the candle body mounted on the base unit, and to control operation of the light source in dependence on the rotational position of the candle body mounted on the base unit and/or wherein the base unit is configured to adjust the intensity of light emitted from the light source and/or adjust the colour of light emitted from the light source in dependence on the rotational position of the candle body.

13. The candle of claim 1 , wherein the proximity sensor is configured, in use, to detect variations in a surface of the candle body indicative of the rotational position of the candle body on the base unit.

14. The candle of claim 1 . wherein the candle body comprises a recess in a portion thereof, and further wherein the proximity sensor is configured, in use, to detect variations in a surface within the recess provided within the candle body.

15. The candle of claim 6 , wherein the light sensor is operable to output a control signal for activating or deactivating the light source in dependence on the presence, absence and/or level of light incident on the light sensor.
