Popular Science - How To Choose LED Light?

- Nov 29, 2017 -

1, LED is not as bright as possible

Ordinary consumers easily into a misunderstanding, when a white LED lights and a warm LED lights put together, that white light than the warm light of the lamp, mistakenly think the white light is better. In fact, our long-term residence, the place to stay, should be selected 4000K and below the color temperature of LED lights, which can effectively reduce or avoid the impact of blue light on human health, for the protection of eyesight is also of great significance. Figure 1 can be very intuitive display 4000K and below color temperature.

2, choose less harmonic content of the lamp

Harmonic more professional, the average consumer is not easy to understand, when the lights can not determine the harmonic content of more and less. Our AC is a 50Hz sine wave, but due to the use of a large number of electronic products and other non-linear load, resulting in our power supply or line current is not a pure sine wave, mixed with other frequency waveforms, the higher the harmonic content, The greater the impact. Harmonic has many kinds of harm, to the user, the energy consumption has increased, will produce the interference to the radio equipment and so on.

3, to reduce the impact of stroboscopic effect

Strobe effect is also a professional term, that is, in a certain frequency of light irradiation, the observed object motion showing static or different from the actual state of the phenomenon. Consumers do not understand well. Stroboscopic effect is also caused by the 50Hz AC, then we put the 50Hz AC into a higher frequency or into DC This problem not solved? ! Indeed, we can take a cell phone or camera shooting video mode to determine, if the display on the screen LED display more jitter, indicating strobe more serious, people's eyesight will be harmful.
