Toppo Lighting Tell You How To Choose LED Lamp

Toppo Lighting tell you how to choose LED Lamp

Home decoration is inevitable to chosee good lamps, the shape of the lamp should be coordinate with decoration style and functions of the lamps. The style and shape of the lamp is the thing  benevolent see benevolence and thewise see wisdom, This article mainly tells the consumer how to choose the right lamps, especially the LED lamps meet the necessary of the lighting environmentand  the requirements of healthy lighting.

1, LED lights are not the brighter the better

Ordinary consumers are easily misunderstanding, when put a white LED lamps and a warm white LED lamps together,they will think the white light brighter than the warm white lamps, the white lamps are better than the warm white. In fact, we should choose the 4000K and warmer white lamps in our long-term living and staying place, which can effectively reduce the impact of blue light on human health, and it is important to protect people’s vision Figure 1 can be very intuitive distuguish 4000K and the lower color temperature.

2, select less harmonic content lamps

Harmonics is technical words for the lamps, ordinary consumers are not easy to understand and not easy to judge the concepts of the harmonic content. Our alternating current is a 50Hz sine wave, power or line current is not a pure sine wave as  we use a large number of electronic products and other non-linear load, our, which is mixed with other frequencies of the waveform, the higher the harmonic content, The greater the impact. Harmonics have many kinds of hazards, the energy consumption increases, the radio equipment will ne influenced and so on.

How can we judge harmonics? We can take a semiconductor radio, close to the LED lights, if the radio noise is greater, it indicate that the harmonic content of LED lights is higher, the radio interference is also more powerful.

3, reduce the impact of stroboscopic effect

 

Strobe effect is a technical term,too. Observed movement of objects showing a static or other different state of motion in a certain frequency of light irradiation. Strobe effect is  caused by 50Hz alternating current, sowhether the problem issolved or not when we use >50Hz alternating current frequency or direct current? It is absolute;y right, we can make a judge based on the conditions when we make a vedio through the phone or camera shooting, if the display screen are more jitter, it means that strobe  effect is more serious, it is harmful to the human eye.
