LED candles use light-emitting diodes (LEDs) as a light source, instead of a traditional flame. The LED is a small semiconductor chip that produces light when an electrical current is passed through it. The LED is typically housed in a clear or frosted bulb that diffuses the light and creates a soft, warm glow.
When you turn on an LED candle, the electrical current flows through the LED, which emits light in a specific wavelength and color. This light is then diffused by the bulb, creating a warm, candle-like glow.
One of the main advantages of LED candles is that they are much safer than traditional candles, as they do not have an open flame. They also tend to be more energy efficient, as they use less electricity to produce the same amount of light as a traditional candle. Additionally, LED candles can be used for many hours without needing to be replaced, making them a convenient and long-lasting lighting option.
