As a common household item in daily life, desk lamp is a kind of lighting equipment, which is usually placed on tables, desks, bedside or other work spaces to provide local light sources for people to read, work, write or engage in other activities at night or in poor light.

The history of desk lamps can be traced back to ancient times. The earliest lighting devices were usually based on fire, such as candles, oil lamps and gas lamps. However, there are some safety and convenience problems in these lighting methods. With the development of science and technology, electric lighting has gradually replaced the traditional lighting mode, and electric lighting has become a new choice.

The first generation of desk lamps usually use light bulbs as light sources, which are simple in design and mainly used to provide basic lighting. With the passage of time, the design and function of desk lamps are constantly innovating to meet different needs. Modern desk lamps usually use LED lamps or energy-saving bulbs to reduce energy consumption and provide brighter and more lasting light sources.

There are various types and designs of desk lamps to meet the needs and aesthetics of different groups of people. The following are some common table lamp types and designs:
