초록 ▼

A flame simulating device includes a substantially translucent shell having a hollow interior, a plurality of colored light sources, positioned within the hollow interior of said shell and a light source driving device for selectively activating each of said plurality of light sources. Each of the light sources are alternately and individually activated to have active periods and such that the surface of said shell is illuminated to produce an animated flame effect. In one example implementation, yellow, orange and red LEDs are positioned at varying heights within the flame-shaped shell and activated on and off in a sequence that follows a set of color transition rules in order to provide a close simulation of the flickering of a flame. During their active periods, LEDs are blinked on and off to conserve power.

대표청구항 ▼

The invention claimed is: 1. A flame simulating device comprising: (a) a substantially translucent shell having a hollow interior and a directional axis; (b) a plurality of colored light sources, adapted to be positioned within the hollow interior of said shell, wherein said light sources include a first light source emitting light having a first frequency, a second light source emitting light having a second frequency and a third light source emitting light having a third frequency and wherein said third frequency is greater than said second frequency and said second frequency is greater than said first frequency; (c) a light source driving device for selectively activating said first, second and third light sources according to the following transition rules: i. if the first light source is active then activate the second light source next; ii. if the second light source is active then activate either the first light source or the third light source next; and iii. if the third light source is active then activate the second light source next; (d) each of said first, second and third light sources being sequentially activated such that the surface of said shell is illuminated and produces an animated flame effect. 2. The device of claim 1, wherein said plurality of light sources include light sources selected from the group consisting of: yellow, orange and red light sources. 3. The device of claim 1, wherein each of said light sources are activated on a mutually exclusive basis to minimize power requirements for the device. 4. The device of claim 1, wherein when one of said plurality of light sources is activated, said light source driving device turns the light source on and off at a selected frequency such that the of periods are not perceivable by a human eye to minimize power requirements for the device. 5. The device of claim 1, wherein said first light source is located below said second light source as measured along the directional axis of said shell and said second light source is located below said third light source as measured along the directional axis of said shell. 6. The device of claim 1, wherein the duty cycle of said second light source is greater than the duty cycle of said third light source and greater than the duty cycle of said first light source. 7. The device of claim 1, wherein said plurality of light sources are positioned in a spaced apart manner at different heights as measured along the directional axis of said shell. 8. The device of claim 7, wherein said plurality of light sources are activated in consecutive order up and down the directional axis of said shell. 9. The device of claim 1, wherein the shape of the shell is selected from the group consisting of: flame-shaped, spherical, tubular, rectangular box. 10. The device of claim 1, further comprising an audio sensor, wherein light source driving device is deactivated when the audio sensor detects sound. 11. The device of claim 10, wherein the audio sensor is positioned in close proximity to the plurality of light sources. 12. The device of claim 1, further comprising a light sensor wherein said light source driving device is deactivated when the light sensor detects light and activated when the light sensor no longer detects light.
