In the state of use, the LED diode 25 is illuminated, and the light passes through the translucent material of the base 3 to generate soft light, and cooperates with the protruding machine. The dynamic combustion effect of the simulated real fire generated by the display surface at the top of the seat 3 makes the product more enjoyable.

In other embodiments, the illumination device provided by the present invention may further include a sensor that acquires a wind signal or a gas flow signal in a state of being windy or airflow, and the control panel 7 converts the wind signal or the airflow signal measured by the sensor into electricity. The signal is used to drive the LED chip to illuminate or flicker, so that in the state of wind or airflow, a flame that flickers by the wind or the airflow is formed on the LED display surface to achieve a dynamic combustion effect; in the absence of wind or airflow In the state of the LED, the LED display surface is not bright, so that the illumination device of the present invention is closer to the actual candle burning state.

In addition to being used for home lighting, in other embodiments, the lighting device of the present invention can also be used in lanterns, wishing lamps, torches, fireplaces, outdoor lighting, wall lighting, etc., when used in home lighting products. When the LED display surface can form a dynamic flame burning effect, or all or part of the LED can be brightly lit to achieve the lighting effect, according to special needs, the LED display surface can also adopt a colorful LED to make the illumination device of the invention blink. Different colors, such as colored lights in wall lighting products.

The above is a further detailed description of the present invention in connection with the specific embodiments, and the specific embodiments of the present invention are not limited to the description. A number of simple derivations or substitutions may be made by those skilled in the art without departing from the inventive concept.
