It is necessary to choose lamps and lanterns for home decoration. The shape of lamps and lanterns needs to be coordinated with the style and function of decoration. The style and shape of lamps and lanterns are matters of different opinions of people with different opinions and wise people with different opinions. There is no need to say more here. This paper mainly tells ordinary consumers how to choose suitable lamps, especially LED lamps, which can not only meet the needs of lighting environment, but also meet the requirements of healthy lighting.

1. LED lamp is not the brighter the better

Ordinary consumers are apt to enter a misunderstanding. When a white LED lamp and a warm LED lamp are put together, they think that the white lamp is better than the warm-tone lamp. In fact, in places where we live and stay for a long time, we should choose LED lamps with color temperature below 4000K, which can effectively reduce or avoid the impact of blue light on human health. It is also very important to protect our eyesight.

2. Choose lamps with less harmonic content

Harmonic is more professional, ordinary consumers are not easy to understand, when choosing the lamp can not judge the harmonic content of more or less. Our AC is a 50 Hz sinusoidal 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 sinusoidal 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, interference to radio equipment and so on.

How can we judge harmonics simply? You can take a semiconductor radio, close to the LED lamp. If the noise of the radio is greater, the higher the harmonic content of the LED lamp, the more serious the radio interference.

3. Reducing the impact of stroboscopic effect

The stroboscopic effect is also a professional term, that is, the observed motion of an object appears to be stationary or different from its actual state of motion under the irradiation of light with a certain frequency change. Consumers don't understand. The stroboscopic effect is also caused by 50Hz alternating current, so we can turn 50Hz alternating current into higher frequency or direct current. Indeed, we can distinguish the shooting video mode of mobile phones or cameras. If the LED lamp screen on the display screen is more jittery, it shows that stroboscopic is more serious, which will harm people's vision.
