Document Type and Number:
Japanese Patent JP2016143547
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To express smooth flame by a compact circuit board whose manufacturing is easy when a candle-like flame is expressed by using LED.SOLUTION: Three COB type LEDs with a color temperature of 1600 K to 2200 K and a diffusion angle of 120° or more are arranged in a concentric circular manner in a spacing of 120°, and illumination timing is controlled by a CPU, so that composed light fluctuates like smooth flame and it becomes possible to see the flame through a diffusion raw material such as a Japanese paper.SELECTED DRAWING: Figure 1
