High Lumen Street Light Housing Supplier Introduces How To Use Table Lamps

High Lumen Street Light Housing Supplier introduces how to use the lamp correctly so that it will not hurt your eyes?

1. The illuminance is inversely proportional to the square of the distance. Because the illuminance of the writing surface under the table lamp is about one time different, it will definitely affect the eyesight, so it is best not to use the table lamp as the writing light source. When writing at night, ensure that the entire room has sufficient brightness. It is strictly forbidden for students to use the lamp to read and write. If reading and writing are inseparable from the lamp, it is a bad eye habit in itself.

2. Keep a distance between the desk lamp and the head, and you cannot directly see the filament of the lighting bulb when you look up. The brightness of the desk lamp should be within the range of reasonable lighting, not too dark or too bright. The upper limit of brightness is based on looking up and seeing the indoor wall scenery immediately, otherwise it will produce “light source near vision”.

3. The light retention generated by close eyes under strong light will weaken the effect of sleep to restore vision and cause genetic dominance. Therefore, the total illuminance of table lamps and indoor lighting cannot be too strong. If you close your eyes and there are book light and shadows, the total illuminance of the writing surface is too strong, which results in light retention. At this time, you should increase the distance between the table lamp and the book, or add a hood to the table lamp to reduce its illuminance. The yellow-green shade of the visible light is best.

4. The color temperature of the yellowish tungsten bulb is more suitable for writing lighting. Some areas have stipulated the use of yellow-green textbooks and workbooks. Except for adult fine work (tracing, assembling, repairing watches, engraving) using desk lamps, the writing desk lamps used by students for learning can only use thermoluminescent light sources such as tungsten light bulbs.
