What kind of eye protection desk lamp is a good desk lamp?
What kind of eye-protecting desk lamp is a good desk lamp? A few years ago, many experts discussed this matter together, and everyone agreed that a good desk lamp for school-age children should meet the following 9 criteria.
1 Certification
The study table lamp must pass the national compulsory CCC certification.
2 light colors
The warm white light color with a color temperature of 30003300K meets the visual needs of children at this stage; if the color temperature is too low, it is easy to get tired, and if the color temperature is too high, it will be excessively stimulated, and there is a risk of injury.
3 Glare
During normal use, there is no dazzling light.
4 Illumination
The desktop illumination is preferably 700-1000lx.
5 Color rendering
Children's eyes are more sensitive, so Ra>90 is recommended.
6 Power
The power should not be too small, the lamp usage time is short, and energy saving is not the main consideration.
7 Strobe
Low-frequency flickering can cause eye fatigue and mental irritability.
8 Range
With a certain height, the lighting surface should be larger and more uniform.
9 Structure
The bracket has a certain length, which is easy to stretch and shrink, and is suitable for multi-purpose use such as computer, painting, and piano.
The above 9 items are summarized based on national standards and application experience. For the consideration of most readers, they only describe their meanings and are not described in accordance with the standard provisions.
