It is inevitable to choose a good lamp for home decoration, and the shape of the lamp needs to be coordinated with the style and function of the decoration. The style and shape of the lamps are things that the benevolent sees benevolence, and the wise sees wisdom. Needless to say here. This article mainly tells ordinary consumers how to choose suitable lamps, especially LED lamps, which can not only meet the needs of the lighting environment, but also meet the requirements of healthy lighting.

1. LED lights are not as brighter as possible
Ordinary consumers tend to fall into a misunderstanding. When a white LED lamp and a warm color LED lamp are put together, they think that the white light is brighter than the warm color, and mistakenly think that white light is better. In fact, in places where we live and stay for a long time, we should choose LED lights with a color temperature of 4000K and below, which can effectively reduce or avoid the impact of blue light on human health, and it is also very important for protecting eyesight.

2. Choose a lamp with less harmonic content
Harmonics are more professional, and it is not easy for ordinary consumers to understand, and they cannot judge the amount of harmonic content when choosing a lamp. Our AC power is a 50Hz sine wave, but due to the use of a large number of electronic products and other non-linear loads, the current on our power supply or line is not a pure sine wave, which is mixed with other frequency waveforms, the higher the harmonic content, The greater the impact. Harmonics have many kinds of hazards. For users, energy consumption increases, and it will cause interference to radio equipment.

How can we simply judge harmonics? You can take a semiconductor radio and put it close to the LED light. If the noise of the radio is louder, the higher the harmonic content of the LED light is and the more severe the radio interference.

3. Reduce the impact of stroboscopic effect
The stroboscopic effect is also a professional term, that is, under the irradiation of light that changes at a certain frequency, the observed motion of an object appears to be static or different from its actual motion state. Consumers do not understand. The stroboscopic effect is also caused by 50Hz alternating current. Then we can change the 50Hz alternating current to a higher frequency or become a direct current. This problem will not be solved? ! Indeed, we can use the video mode of the mobile phone or camera to judge. If the LED light displayed on the display screen is jittery, it indicates that the stroboscopic flicker is serious and will harm human eyesight.
