| 摘要 |
The present invention relates in a first aspect to a device for simulating combustion (2). The device (2) comprises at least one combustion-simulating element, preferably in the form of a flame-simulating element (20), having at least one fluorophoric region (20b) containing fluorophores which are capable of emitting visible light upon irradiation at a predetermined wavelength. The device (2) also comprises a radiation source (18) relatively positioned so as to irradiate said at least one fluorophoric region (20b) of the or each combustion-simulating element (20). In use, the or each fluorophoric region (20b) emits visible light by fluorescence due to irradiation by the radiation source (18), thereby simulating combustion. The device (2) is particularly suitable as a heating device, in which case a heat source (24) is provided. The present invention also relates to a spark simulating device (22) which comprises at least one optical fibre (50), and a light source (52), with the light source being operably coupled to the optical fibre(s) (50). The device (22) is arranged to transmit light from a first end of the fibre(s) (50a) to a second end (50b). There is also provided means for creating an observable pulse of light at the second end of the fibre(s) (50b) so as to simulate a spark. |
