Traditional long-term medical lighting are halogen lamp, and later, it began to use metal halide lamp as a light source. Halogen lamps, metal halide lamps are light in all directions, the whole space of the typical divergence divergent light. Compared with traditional medical lighting products, LED has inherent advantages in the realization of fixed point, directional lighting, high-intensity lighting, dimming control, to achieve high color, low spectrum damage, etc., can overcome the lack of a strong conventional medical lighting.
From the application, there are two types of LED medical, one hospital general lighting, such as wards, offices and corridor using various lighting; the second is healthcare dedicated light source, such as: (1) peep lighting for lesion detection, observation lighting; (2) surgical lighting, LED operation shadowless lamp; (3) disinfection, sterilization radiation light source, the use of ultraviolet light for medical equipment, medical equipment and medical utensils disinfection and sterilization, high speed, high efficiency advantages ; (4) phototherapy - optical radiation therapy sources, the use of the biological effects of light with a specific wavelength of light so that the body skin or certain tissue cells or inhibiting the growth spawned long to achieve therapeutic purposes; (5) the pathological examination of the light source, with 570nm green light can be measured ESR, with 640nm and 900nm IR light ray can detect chlorine content of the blood, it can be diagnosed with a 488nm blue whether bladder cancer.
From the LED light source is, LED have many medical applications, such as: (1) ultraviolet light, can be sterilization, treatment of skin diseases, beauty, and so on; (2) infrared light, can in anti-inflammatory, analgesic, promote metabolism, etc. ; (3) Blu-ray, 425nm ~ 475nm range to treat neonatal jaundice, 446nm ~ 477nm range is conducive to enhancing the vitality of the human brain, and the like; (4) red light, can promote cell synthesis, and promote wound healing, treatment of many diseases ; (5) are mixed with white light, can satisfy different treatment needs, different color temperature of white light irradiation can be used to adjust the treatment of insomnia.
LED medical market potential, good prospects, it is obvious to see. However, LED medical technology high gold content, in order to do a good job is not easy. But the other way round, now is precisely the intense competition in the LED market is no technical gold products. So, we do not develop, to develop on the gold market from art to start. Moreover, in addition to medical care abroad LED giants, the current level of domestic enterprises is generally not high, I would like to develop still have a chance.
