Therefore, when choosing the style of the lamp, it is necessary to pay attention to whether the material of the lampshade can soften the light.

Light source selection:

The light sources of bedside folding Table Lamps generally fall into three categories: incandescent lamps, tungsten halogen lamps and fluorescent lamps. The three types of light sources have their own advantages and disadvantages. Different people may like the light color and brightness of different light sources, and they should be suitable for each person. In order to project most of the light onto the desktop, the light source of the bedside folding Table Lamp is usually installed horizontally or downward.　

When the bedside folding Table Lamp is in the normal working position, there are three main optical performance requirements: 　
(1) Light-shielding: When a person is in a normal sitting posture, the eyes should be horizontal, and the inner wall of the lampshade and the light source should not be seen; 　
(2) Desktop illumination requirements: the working area illuminated by the folding Table Lamp should be ≥250lx, and the minimum illumination should be ≥120lx; 　
(3) Illumination uniformity requirements: It should be ensured that the illuminance is relatively uniform in the work area illuminated by the folding Table Lamp, and no particularly bright or dark spots can be produced. Only by ensuring these three basic optical performance requirements can the eye fatigue be relieved and the eye can be weighed. It deserves to be a writing folding Table Lamp.　

When purchasing a writing folding Table Lamp, in addition to checking its optical performance, you should also check whether other performances are qualified.　One, one pull, two adjustments, three shakes, four touches. "Pull" means to unplug the power cord from the socket and pull the power cord out of the lamp cavity to see if the power cord is firmly connected. The power cord cannot fall off from the lamp cavity. "Adjustment" refers to adjusting the various working positions of the folding Table Lamp. When adjusting, no sound can be made, and the working position should be able to be easily and reliably locked after adjustment. "Shaking" refers to adjusting the folding Table Lamp to the most unfavorable working position, and then gently shaking the surface on which the folding Table Lamp is placed, to see whether the folding Table Lamp is easy to tip over, and the folding Table Lamp is not stable and easy to tip over. "Touch" refers to whether the lampshade and other heat-generating parts that are easy to touch during use are hot after the folding Table Lamp has been lit for a period of time (2 hours), so as to prevent accidental burns when using it in the future.
