In an electronic candle, the LED 25 is housed in the base 3 and in an operating state, the LED 25 is lit, the light emitted by the LED 25 passes through the translucent material of the base 3 to generate a soft light and in combination with the dynamic flare effect simulates a real flame generated by the display surface that protrudes from the top of the base 3, a better ornamental value of the product thus being obtained.

In other embodiments, the illumination device provided by the present invention may further comprise a sensor, and in the presence of wind or air flow, the sensor receives a wind presence signal or a an air flow presence signal, and the control panel 7 converts the wind presence signal or the airflow presence signal detected by the sensor into an electrical signal, so as to trigger the ignition of the chips LED with a flashing or permanent ignition, such that a bouncy flame swept by wind or airflow is formed on the LED display surface in the presence of wind or airflow , thereby obtaining a dynamic outbreak effect. In the absence of wind or air flow, the LED display surface is fixedly lit without blinking, so that the lighting device according to the present invention is close to a state of flare. real candle.

In addition to home lighting, in other embodiments, the lighting device according to the present invention can also be used in lanterns, wish lanterns, torches, chimneys, outdoor lighting and lighting. festive wall and other products. When used in household light bulb products, the LED display surface may form a dynamic flare effect, or all or a portion of the LEDs are permanently lit, so as to realize the lighting effect. According to specific requirements, the LED display surface may further comprise LEDs of all colors, so that the lighting device according to the present invention switches between different colors, for example a color lamp in products. wall lighting.

The above content further constitutes a detailed description of the present invention in combination with specific embodiments, and it should in no way be inferred that the specific implementation of the present invention is only limited to these descriptions. For those skilled in the art, several simple withdrawals or replacements can be made without departing from the concept of the present invention.
