Abstract: A novel holographic electric simulated flame generating device, characterized in that it comprises a light-diffusing plate and an electric circuit board disposed behind the light-diffusing plate; a group of LED electronic scanning light source array which irradiates directly upon the light-diffusing plate is disposed on the electric circuit board; each LED light on the LED electronic scanning light source array is controlled by a controller. The present invention attains simulated flaming effects by a specially processed light-diffusing plate and programming control method. It has the advantages of being noiseless, low-voltage, low power consumption and low manufacturing costs. The present invention is relatively simple in structure and therefore may be made lighter and thinner and then applied to a simulated flame apparatus as a flame generating device. As a result, the practical applications of the present invention are more diverse and human-oriented.
