1. The advantages of led lights

The reason why led lights are so popular is because they have many advantages that other lamps do not have.

1. The design of the LED lamp adopts the design form of secondary optics. We illuminate the light of the LED lamp into the area required for illumination, which can make the lighting efficiency higher. Therefore, many places are willing to choose to use the LED lamp. The light-emitting diode of the led lamp is a low-voltage device, the voltage is safe to use, and it is particularly suitable for use in public places.

2. The light decay of the LED lamp is very small, and the service life is also very long. The LED lamp still has a high use value after more than 10 years of use, and it can be used for more than 50,000 hours. They are in the process of continuous use for one year The light decay will not exceed 3%.

3. The light source of the LED lamp is unidirectional, and there will be no diffuse reflection to ensure the efficiency of lighting.

Second, the disadvantages of led lights

Although led lights have many advantages, even the perfect things have their own shortcomings, and led lights also have certain shortcomings. The disadvantages of led lights are as follows:

1. Although the light attenuation of the LED is very low, this is basically for high-power LED lamps, and the light attenuation of low-power LED lamps is still relatively large, and the service life of such low-power LED lamps is far. The time without high-power lamps is long.

2. The light source of the led lamp is white light. Due to the individual defects in the manufacturing process and the matching error of the lens, it will make the led lamp easy to form a yellow circle when it is used. This yellow circle will affect the illumination of the lamp. effect.

3. There is mercury pollution in the production process and after use and disposal. This mercury pollution has a great harm to the natural environment. At present, western countries attach great importance to mercury pollution, and many people in China have increasingly realized the harmfulness of mercury pollution.

4. In fact, this kind of led lamp is also very easy to damage, short life, energy saving but not saving money. This sentence is the most true portrayal of the led lamp.
