Points to Note When Choosing A Table Lamp

Posted by Trade Global on August 9th, 2022

There are many types of table lamps today, 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 want is a product that is practical, energy-efficient, and reliable. In daily life, when children do homework, draw, and read picture books, they must pay attention to the problem of lighting. A suitable eye protection lamp has the characteristics of a comfortable light source, no flickering, and reduced visual fatigue.

The correct placement of the table lamp should be in front of the left hand, not directly above or right above. Comparing the size of the shadow area under different placement positions, it is obvious that when placed in the upper left, the shadow area is relatively small.

Table lamps belong to individual lighting, the light is right in front of you, and inappropriate light can easily cause eye discomfort. The light source of the eye protection table lamp requires stable, comfortable, and non-flickering, reducing visual fatigue. In addition, the illuminance of the table lamp needs to meet the 300-500Lux illuminance of the work table, and the bright light should avoid the appearance of myopia.

When the lamp is in the normal working position, the main optical performance requirements are three points:

(1) Shading

In a normal sitting position, people's eyes look in the horizontal direction, and they should not see the inner wall of the lampshade and the light source;

(2) Desktop illumination requirements

The working area illuminated by the desk lamp should be 250lx-500lx, and the minimum illumination should be ≥120lx.

(3) Illumination uniformity requirements

It should be ensured that in the working area irradiated by the desk lamp, the illumination is relatively uniform, and no particularly bright or dark spots can be produced. Only by ensuring these three basic optical performance requirements can reduce eye fatigue and be called a high-quality desk lamp.
