Description

A multifunctional LED desk lamp

technical field

The invention belongs to the field of solid optoelectronic application technology, and in particular relates to a multifunctional LED desk lamp integrating lighting, mite removal and physiotherapy functions.

Background technique

In recent years, with the rapid development of optoelectronic technology, LED technology has become more and more mature. LED light source has achieved high power, long life, low price, and developed multiple bands of red light, blue light, yellow light, ultraviolet light and suitable for lighting White LED light source; At present, products based on LED lighting are gradually replacing traditional lamps and becoming an emerging industry that saves electricity and protects the environment. In addition to lighting applications, LED light sources also have good application prospects in non-lighting fields. Among them, red LEDs illuminate biological tissues, which can produce positive biomedical effects, improve local blood circulation, enhance the oxygen-carrying capacity of red blood cells, and promote tissue regeneration. Metabolism, enhance the vitality of the immune system, play anti-inflammatory and analgesic, regulate secretion, relieve fatigue and other physiotherapy functions. At the same time, the LED light source has a narrow spectrum, and the same light source does not contain harmful bands. Therefore, LED red light is also called "the light of health". The medical effect was first studied by NASA and applied to astronauts' health physiotherapy; the ultraviolet LED light source has a bactericidal effect and can be used to kill bacteria and mites on pillows and bedding. At present, LED lamps and related patents on the market only focus on the lighting or aesthetic functions of LEDs, such as "a multi-functional LED desk lamp" (patent number 201220455659.2), and some patents use LEDs as special physical therapy equipment, such as "New LED Light Therapy Health Care Device" (Patent No. 201110086214.1); therefore, there is no desk lamp that can realize the lighting function of LED light and non-lighting functions such as physical therapy and mite removal. In fact, LED light-emitting tubes with different wavelengths have exactly the same requirements for power supply. With the control system, the lighting function of LED light and non-lighting functions such as physiotherapy and mite removal can be fully integrated. Compared with other special lighting or physiotherapy products, it is not only more economical, but also in It also brings great convenience in use.
