LED in the field of medical equipment

Date:2018-04-16Views:1897Tags:
Unconsciously, light-emitting diodes (also called light-emitting diodes, abbreviated as LED), which have significant energy-saving characteristics, are playing an ever-increasing role in people's lives - the light source of mobile phone keys, the indicator light of notebook computers, and the automobile defense system. Fog lights, indoor lights... At the Shanghai World Expo, the brilliant landscape brought by LED products is particularly eye-catching. In the field of medical lighting, at present, there are more than 270,000 medical and health institutions in China, and there is a huge amount of surgical shadowless lights. The LED energy-saving market is very broad. This opportunity has attracted the industry's strong interest and funding. According to information released by the Ministry of Science and Technology, Harbin Haige Science and Technology Development Co., Ltd. was responsible for the "Semiconductor Lighting Project" major project in the national "Eleventh Five-Year Plan" 863 Plan new materials technology project "LED application in medical equipment", not long ago Successfully passed the acceptance of the Ministry of Science and Technology. This progress made people further see the good prospects for the application and industrialization of LEDs in the field of medical lighting.

  Medical lighting energy-saving appeal
  Research shows that LED has the characteristics of point light source and solid-state light source, and its long lifetime of light emission can save energy, high shock resistance, small size, fast response, and high color saturation. In recent years, based on the demands of environmental protection and energy conservation, the European Union, Canada, some states in the United States, and Australia have successively announced specific plans to prohibit the sale or use of incandescent light bulbs, encourage the development of LED lighting technology, and China and Japan have also formulated LED reward programs for development.

  Industry analysis, in the medical field, in addition to surgical shadowless lights, partial inspection of lighting fixtures, such as oral lights, endoscopic lamps; surgical room lighting for regional lighting, surgical preparation lighting; light therapy for the treatment of special conditions Equipment, such as photodynamic therapy instrument, neonatal jaundice treatment instrument, ultraviolet disinfection lamp, etc., are suitable for promoting LED medical lighting.

  LED surgical shadowless energy saving 40%
  It is understood that the subject of the "LED application in medical equipment" subject is Harbin Haige Technology Development Co., Ltd. After three years of research and development, R&D personnel used high-power white light emitting diodes instead of traditional halogen lamps as shadowless lighting sources, and eventually developed a new type of medical LED surgical shadowless lamp.

  Relevant data show that this surgical shadowless lamp can achieve multi-level illumination control. In the past, the obvious problem of the LED was heat dissipation. Improper heat dissipation may cause degradation of the luminosity and the service life of the LED lamp. In this regard, the research group developed a patented technology for low thermal resistance bonding of heat sinks and power devices, and realized a fully metalized heat dissipation path from LED chips to aluminum heat sinks, effectively reducing the thermal resistance of the system. The technical indicators of the products meet the requirements of the national pharmaceutical industry standard YY0627-2008.

  According to experts, compared with the traditional light source shadowless lamp, LED surgical shadowless lamp has the following advantages: light source life is much better than traditional halogen lamp, energy saving reaches more than 40%; has the characteristics of different colors from the traditional shadowless lamp, increased human blood and The color difference of other tissues and organs makes the vision more clear and provides better protection for the success of the operation. Without infrared and ultraviolet radiation, it can effectively avoid the loss of water and infection in the surgical wound; the illumination of the working surface can be adjusted through the illumination remote control system. The light is more comfortable and reduces the doctor's visual fatigue. A year-long clinical study carried out by the Chinese People's Liberation Army No. 21 Hospital and the Second Affiliated Hospital of Harbin Medical University showed that this LED surgical shadowless lamp can meet the needs of normal clinical applications.

  Relevant experts also stated that medical lighting belongs to the medical device category and that entry barriers are high. Developed countries have just started in this respect. The gap between China and the international advanced level is relatively small. The setting of “LED application in medical equipment” is subject to It is of great significance to improve China's LED medical lighting technology and promote the application of LED in the field of medical lighting and industrial development in China.
