Lamp selection element one: anti-glare
Glare is one of the important causes of visual fatigue, the choice of anti-glare lamps can effectively reduce unnecessary harm.
One is that the lamp itself has a shading Angle, which effectively reduces glare. The optical design of the lamp, with a honeycomb barrier or reflective cup, etc., this optical design to reduce glare can also be anti-glare; There is another, related to the color of the lamp itself, if the lamp is black, it can also effectively reduce glare.
Lighting selection element two: no stroboscopic
Stroboscopic is actually because of fluctuations in the internal current of the lamp, causing its light to flicker a little. Stroboscopic lamps can cause visual fatigue and even cause certain damage to the human eye. Consumers usually buy lights, you can use the camera lens of the mobile phone to shoot this lamp, if in the process of shooting found a stripe condition, it may be a problem with the strobe of the lamp.
Lamp selection element three: high Color Rendering Index
The color rendering index, as the name suggests, is the ability of the light of the lamp to restore the color of the item. We can think that the sun's ability to restore the color of the item is 100, if the color rendering index of the lamp can reach 90, 95 or even 98, it means that its color rendering index is very good. In the home life, the restaurant has fruits, meals, the color index of this place is relatively high, it will make people's appetite increase; In addition, where children play or draw, the color rendering index should also be relatively high.
Lamp selection element four: illuminance value
Illuminance is actually our usual understanding of the room light is not bright enough, we generally for the living room or study requires its illuminance will be higher. In writing places, such as children's desks or adults writing and reading writing surface, the national "GB50034-2004 architectural lighting design standards" require it to reach 300 (lx) or more, for general living places, the illumination can reach 150 (lx).
