Description

Adjustable desk lamp

Technical Field

The utility model belongs to the field of illumination, and particularly relates to an adjustable table lamp.

Background

The desk lamp generally refers to an electric lamp with a base, which is placed on a desk, but with the progress of technology, the appearance and the shape of the desk lamp are also continuously developed, and the magnetic desk lamp capable of being adsorbed at any position is gradually developed, so that the desk lamp is small and exquisite and convenient to carry. The desk lamp has the main functions of lighting, is convenient for reading, learning, working and the like, and has far exceeded the value of the desk lamp.

Many parents buy eye-protecting lamps for children to protect eyesight, and first, the degree of the lamp bulb is proper. If the degree is too low, the light rays on the book are darker, and the handwriting cannot be easily seen, so that the visual fatigue is caused, the myopia is caused for a long time, and the myopia treatment becomes daily necessary. If the degree of the bulb is too high, the too strong light can be reflected to our eyes through the white paper surface, so that glare is generated, the pupils are continuously contracted, and eye pain and headache are caused. Second, the height of the desk lamp is also important. Usually, when eyes are 30 cm away from books, handwriting can be seen clearly, excessive fatigue can not be caused, the calculation is carried out, the height of the desk lamp is 40 cm to 50 cm away from writing, and therefore sufficient reading illumination is ensured, and the surrounding environment has certain brightness. If the desk lamp is too low, the light can be radiated to an excessively small range, and a piece of paint is black around the desk lamp. The reference object for long-range viewing is lost, so that each eye regulating system is in a tension and compression state only in the near region, eye fatigue is easy to occur, and the eye fatigue is accumulated rapidly, so that 'light source myopia' is caused. If the desk lamp is too high, the light rays can directly illuminate eyes of people to generate glare; meanwhile, the short-distance strong light can cause light retention phenomenon on retina, can tighten eye muscles and accelerate vision decline, so that knowledge for treating myopia is mastered at ordinary times.

It is therefore important to obtain a table lamp which overcomes the above drawbacks and enables a highly controllable training of myopia prevention with respect to the angle.
