Description

Telescopic table lamp

Technical Field

The utility model relates to the technical field of lighting lamps, in particular to a telescopic desk lamp.

Background

The desk lamp is a common indoor lighting lamp in people's life, is used for illuminating at night in a small range, and most of desk lamps in the existing market adopt an LED lamp to provide illumination.

However, although the desk lamp can illuminate, it cannot play other beneficial roles in human body. Modern people often stay indoors for a long time without going out due to living habits, and have less chance to directly receive solar illumination even going out, so that calcium deficiency is easily caused. The principle of sunlight for supplementing calcium to human bodies is that although a large amount of calcium is taken by human bodies every day, the absorption of calcium is very limited. The UVB band ultraviolet light (specific wavelength is 265-228 nm) in sunlight can promote the 7-dehydrocholesterol contained in the epidermis and dermis of a human body and an animal body to be converted into vitamin D3, so that the absorption of calcium by an intestinal tract is promoted, the calcium phosphorization of bones is induced, and the aim of calcium supplement is achieved. Even if people get warm by shining the sun indoors, more than 50% of ultraviolet light can be filtered by indoor window glass, and the human body cannot receive the ultraviolet light irradiation, so that the aim of supplementing calcium by using sunlight cannot be achieved even if the people shine the sun indoors.

Most of table lamps in the market mainly increase the mechanical function of table lamps, such as increasing the function of a mobile phone support and increasing the function of a pen container.
