National 863 project LED application in the field of medical equipment by the Ministry of science and technology acceptance

The day before, as the "863 plan new material of semiconductor lighting project" in Harbin, shadowless Haige science and Technology Development Co Ltd developed LED days before surgery, passed the acceptance of experts organized by the Ministry of science and technology.

The results of the use of high-power white LED to replace the traditional halogen lamp as a light source shadowless lamp, successfully solves the problem of high efficiency high color rendering index of high power LED package, high-power LED constant current drive, high-power LED heat dissipation, illumination control, two optical design problem. The light distribution is better than similar foreign products (foreign commonly used lens mode); in control, using the infrared wireless remote control method realizes the control of shadowless lamp illumination light, flexible and convenient; the radiation of high power LED, successfully developed a patented technology of radiator and power devices with low thermal resistance junction. The cooling channel of metal from the LED chip to the aluminum radiator, effectively reduce the system resistance. Products of the technical indicators have reached the national pharmaceutical industry standard YY 0627-2008 requirements, by showing that clinical trials in No.211 Hospital of PLA and the Second Affiliated Hospital of Harbin Medical University for more than a year, the product has to meet the normal requirements of clinical application.

Compared with the traditional light source, has the following advantages of LED operation shadowless lamp:

1, due to the high efficiency, high power LED, so most of the time can be used in full power 50%, the energy saving effect is obvious;

2, the white LED is different from the ordinary operation shadowless lamp light source the chromaticity characteristics, increase the color characteristics of blood and other tissues in the body, making the visual organ, the doctor's surgery is more clear, in the flowing, various organizations, human penetration in the blood is easy to distinguish more organs, this is a common operation shadowless lamp does not have;

3, LED light source without infrared, ultraviolet radiation, can effectively avoid the operation of the wound water loss and infection, but also for doctors to create a more comfortable operating environment;

4, LED light source is the life of the traditional halogen tungsten lamp 20 times, reducing the frequent replacement of the bulb trouble;

5, using two optical design reflector array, spot shape specification, the spot size is increased to 4 times the traditional similar shadowless lamp spot area has a high utilization rate of the light, so that the surgeon's operation more convenient;

6, the use of remote control system, easy to adjust the illuminance, make the light more comfortable, reduce the doctor's visual fatigue.

Data show that the market demand of domestic every year shadowless lamp in 20 thousand above, at the same time, the huge social ownership is in urgent need of energy saving, so the market prospect is very broad LED shadowless lamp. Our province is planning in the township hospitals or medical institutions above the comprehensive promotion of LED operation shadowless lamp. To this end, Hagrid, the company is actively reporting medical equipment production license and product LED shadowless medical device registration, perfect batch production fixtures and all kinds of test equipment for the early investment in mass production.
