There are many kinds of table lamps now, and the bulbs are divided into energy-saving lamps, incandescent lamps and LED bulbs. Control methods include: switch control, touch control, adjustable brightness and even voice control. But what consumers need is practical, energy-saving and reliable products. Under the national 11th Five-Year Plan, the popularity of energy-saving products such as LED has been further promoted.

Table lamp basic requirements:
1, shading
In a normal sitting position, when people look horizontally, they should not see the inner wall of the lampshade and the light source.
2, desktop lighting requirements
The working area irradiated by the desk lamp should be 250lx-500lx, and the minimum illumination should be greater than 120lx.
3, lighting uniformity requirements
In the work area where the desk lamp is illuminated, it is necessary to ensure that the illumination is relatively uniform, and no special bright spots or black spots can be generated. Only by ensuring these three basic optical performance requirements can we alleviate eye fatigue, which is the so-called writing desk lamp.
