Flame effect fire with simulated LED flame patterns

摘要

A combustion effect device for use in a heating apparatus 10 comprises an array of light sources 28, which may be light emitting diodes, whose illumination is independently controllable. Light from the plurality of light sources is arranged to impinge on a display 32, which may be a translucent screen 32, to simulate flames. The light may also be directed towards a translucent simulated fuel bed 34 to simulate a glowing bed. The array of LEDs 28 may be circular and they replace the spinner used in conventional flame effect fires. The independent control may consist of a microprocessor (40, Figure 2), The LEDs 28 and microprocessor 40 may be located on a substrate (36, Figure 2) that may be planar. The light sources 28 may produce light of the same colour or of two or more different colours. The microprocessor 40 may be programmed to produce a range of different LED patterns (Figures 2 and 3) that realistically produce a flame effect when they illuminate the screen 32. The apparatus may also include a heater 26 that may be electric or gas-fuelled. The main use is as a domestic household flame effect fire.
