After night falls, the electric light will help us solve the lighting problem. Electric lights are essential appliances in the home. The lamps sold on the market are mainly divided into LED lamps and incandescent lamps. Is it correct that led lights are more energy efficient than incandescent lights? What is the difference between led lights?
Is it correct that led lights are more energy efficient than incandescent lights?
It is correct that led lamps are more energy efficient than incandescent lamps, because the luminous efficiency of led lamps is much higher than that of incandescent lamps. With the same brightness, led lights consume much less power than incandescent lights, and the brightness of led lights is much higher than that of incandescent lights.
In the same environment, a 100-watt LED lamp can achieve satisfactory brightness, while an incandescent lamp requires 200 watts to achieve satisfactory brightness. As we all know, the higher the wattage, the higher the power consumption, so it is correct that LED lights are more energy efficient than incandescent lights.
The difference between incandescent lamps and led lamps
The first difference between incandescent lamps and LED lamps is the different light-emitting principles. Incandescent lamps, also known as light bulbs, work on the principle that current flows through the filament to generate heat, and the spiral filament continuously gathers heat so that the filament temperature reaches more than 2000 degrees Celsius, and the filament is in an incandescent state, just like burning iron can emit light.
The higher the temperature of the filament, the brighter the light, so it is called an incandescent lamp. When an incandescent lamp emits light, a large amount of electrical energy is converted into heat energy, and only a small amount is converted into useful light energy.
LEDs are green light sources. The LED lamp is driven by DC, no flash, no infrared and ultraviolet components, no radiation pollution, high color rendering, and strong luminous direction.
Not only that, the dimming performance of LED light is good, and there is no visual error when the color temperature changes. In addition, the cold light source has low heat and can be safely touched. It can not only provide a comfortable light space, but also meet people’s physical health needs. It is a healthy light source that protects eyesight and is environmentally friendly.
