Application

Unconsciously, light-emitting diodes (also known as light-emitting diodes, or LEDs) with significant energy-saving features are becoming more and more popular in people's lives - the light source of mobile phone keys, the indicator light of notebook computers, and automobile protection. Fog lights, indoor lighting... At the Shanghai World Expo, the beautiful 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 the number of surgical shadowless lamps is huge. The LED energy-saving transformation market is very broad. This business opportunity has attracted a lot of interest and capital investment from the industry. According to the news released by the Ministry of Science and Technology, Harbin Hager Technology Development Co., Ltd. is responsible for the “Electrical Equipment Project” in the new material technology field of the “Eleventh Five-Year Plan” 863 Program. Successfully passed the acceptance inspection organized by the Ministry of Science and Technology. This progress has led to further seeing the good prospects of LED application and industrialization in the field of medical lighting.

Energy-saving appeals for medical lighting Research shows that LEDs have the characteristics of point light source and solid-state light source, and have a long light-emitting life, which can save energy, high shock resistance, small volume, fast response, and high color saturation. In recent years, based on the demands of environmental protection and energy conservation, the EU, Canada, some states in the United States, Australia and other countries have announced specific plans to ban the sale or use of incandescent light bulbs, and encourage the development of LED lighting technology. China and Japan have also developed incentive plans for LED development.

According to industry analysts, in the medical field, in addition to surgical shadowless lamps, local inspection of lighting fixtures, such as dental lamps, endoscope lamps; surgical lighting for regional lighting, surgical preparation lighting; light therapy for the treatment of special diseases Equipment, such as photodynamic therapy devices, neonatal jaundice treatment devices, ultraviolet disinfection lamps, etc., are suitable for promoting LED medical lighting.

LED surgery shadowless lamp energy saving 40%
It is understood that the "LED application in medical equipment" project is undertaken by Harbin Hager Technology Development Co., Ltd. After three years of research and development, the R&D personnel replaced the traditional tungsten halogen lamp with a high-power white light-emitting diode as a light source for the shadowless lamp, and finally developed a new medical LED surgical shadowless lamp.

Relevant data show that this kind of surgical shadowless lamp can achieve multi-level regulation of illumination. In the past, the obvious problem of LEDs was heat dissipation. Improper heat dissipation may cause the luminosity and service life of LED lamps to be attenuated. In this regard, the research team developed a patented technology for low thermal resistance bonding of heat sinks and power devices, which realized a fully metallized heat dissipation channel 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 without shadow, the LED surgical shadowless lamp has the following advantages: the life of the light source is much better than the traditional tungsten halogen lamp, and the energy saving is over 40%; it has the characteristics of the color product different from the traditional shadowless lamp, which increases the human blood and The color difference of other tissues and organs makes the field of vision clearer, which provides better guarantee for the success of the operation; no infrared or ultraviolet radiation can effectively avoid the water loss and infection of the surgical wound; the illumination of the working surface can be adjusted by the illumination remote control system, so that The light is more comfortable and reduces the visual fatigue of the doctor. A more than one year of clinical research conducted by the 21st Hospital of the Chinese People's Liberation Army and the Second Affiliated Hospital of Harbin Medical University showed that this LED surgery shadowless lamp can meet the needs of normal clinical applications.

Relevant experts also said that medical lighting belongs to the category of medical devices, and the threshold for entry is 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 for It is of great significance to improve China's LED medical lighting technology and promote the application and industrial development of LED in China's medical lighting field.
