Led lamps are more energy-efficient than incandescent lamps, right?
Correct.
LED lamps are light-emitting diodes, which use solid semiconductor chips as luminescent materials. Compared with traditional lamps, LED lamps are energy-saving, environmentally friendly, and have good color rendering and response speed.
(1) Energy saving is the most prominent feature of LED lights
In terms of energy consumption, the energy consumption of LED lamps is one-tenth that of incandescent lamps and one-fourth that of energy-saving lamps. This is one of the biggest features of LED lights. People nowadays advocate energy saving and environmental protection, and it is precisely because of this feature of energy saving that the application range of LED lights is very wide, making LED lights very popular.
(2) LED can work in high-speed switching state
When we usually walk on the road, we will find that every LED screen or picture is unpredictable. This shows that LED lights can be switched on and off at high speed. However, for the incandescent lamps we usually use, it cannot achieve such a working state. In normal life, if the switch is switched too many times, it will directly cause the filament of the incandescent lamp to break. This is also an important reason for the popularity of LED lights.
(3) Environmental protection
The LED lamp does not contain any heavy metal materials such as mercury, but the incandescent lamp contains it, which reflects the environmental protection characteristics of the LED lamp. Nowadays, people attach great importance to environmental protection, so more people are willing to choose environmentally friendly LED lights.
Incandescent lamp
1. Working principle: Incandescent lamp is also called tungsten lamp. A large amount of heat is generated when the current passes through the filament, making the temperature of the filament above 2000 degrees Celsius and in an incandescent state, so it is called an incandescent lamp.
2. Advantages: The incandescent lamp is closest to sunlight, with good color rendering index 99-100; the price is cheap.
3. Disadvantages: Only about 10% of the electric energy consumed by incandescent lamps can be converted into light energy, and the rest is lost in the form of heat energy, and the service life usually does not exceed 1000 hours. Two words: no energy saving, short life span.
