Unconsciously, light-emitting diodes (LEDs) with significant energy-saving characteristics are playing an increasingly diverse role in people's lives - serving as the light source for mobile phone buttons, indicator lights for laptops, anti fog lights for cars, lights... At the Shanghai World Expo, the stunning scenery they bring is particularly eye-catching. In the field, there are currently over 270000 medical and health institutions in China, with a huge number of shadowless surgical lamps and a vast market for energy-saving renovations. This business opportunity has attracted strong interest and capital investment from the industry. According to the news released by the Ministry of Science and Technology, the major project 'Application of LED in Medical Equipment' of the National 'Eleventh Five Year Plan' 863 Program New Material Technology Field Project undertaken by Haige Technology Development Co., Ltd. recently passed the acceptance organized by the Ministry of Science and Technology. This progress further highlights the promising prospects for the application and industrialization of LED cold light source accessory modules in the medical field.

It has the characteristics of point light source and solid-state light source, with a long emission life, energy saving, high shock resistance, small size, fast response, and high color saturation. In recent years, based on the demand for environmental protection and energy conservation, the European Union, Canada, some states in the United States, Australia and other countries have successively announced specific plans to ban the sale or use of incandescent light bulbs, encourage the development of technology, and China and Japan have also formulated incentive plans for the development of LED medical electronic components. Industry insiders analyze that in the medical field, in addition to surgical shadowless lamps, local inspection lighting fixtures such as oral lamps and endoscope lamps are also used; Surgical room lighting and surgical preparation lighting used for regional illumination; Light therapy equipment used for the treatment of special diseases, such as photodynamic therapy devices, neonatal jaundice treatment devices, ultraviolet disinfection lamps, etc., are suitable for promoting LED cold light source accessory modules for medical lighting.

The undertaking unit for the application project in medical equipment is Haige Technology Development Co., Ltd. After 3 years of research and development, the researchers used high-power white light-emitting diodes to replace traditional halogen lamps as the lighting source for shadowless lamps, and finally developed a new type of medical LED surgical shadowless lamp. According to relevant information, this surgical shadowless lamp can achieve multi-level illumination control. The most obvious problem with LED in the past was heat dissipation, and improper heat dissipation may lead to a decrease in the brightness and service life of LED lighting fixtures. In response, the research team has developed a patented technology for low thermal resistance bonding between heat sinks and power devices, achieving a fully metalized heat dissipation channel from aluminum heat sinks, effectively reducing the system's thermal resistance. The technical indicators of the product meet the requirements of the national pharmaceutical industry standard YY 0627-2008.

According to experts, compared with traditional light source shadowless lamps, LED surgical shadowless lamps have the following advantages: the lifespan of the light source is much better than traditional halogen lamps, and energy saving can reach more than 40%; Having color characteristics distinct from traditional shadowless lamps, it increases the color difference between human blood and other tissues and organs, making the field of view clearer and providing better assurance for successful surgery; No infrared or ultraviolet radiation, can effectively prevent surgical wound dehydration and infection; The illumination of the work surface can be adjusted through the illumination remote control system, making the light more comfortable and reducing visual fatigue for doctors.The clinical research carried out by the Second 11 Hospital of the Chinese People's Liberation Army and the Second Affiliated Hospital of Harbin Medical University for more than one year shows that this LED surgical shadowless lamp can meet the needs of normal clinical applications.
