With the rapid development of led lighting industry, industry competition is becoming more and more intense, many China Led lighting manufacturers focus on other areas, such as hospitals. By means of studying the LED lighting energy saving plan in the first affiliated hospital of Chongqing medical university, analysis feasibility and necessity of its application and dissemination, mainly from the product performance, running effect and economic benefits and market potential and so on. First affiliated hospital of Chongqing medical university, its projects have a total investment of 1.315 million yuan. Among then, LED shadowless lamp for operation is about 700000 yuan, the double side LED lights and LED flat lamp 615000 yuan. After the application of integrated LED lighting solutions, first affiliated hospital of Chongqing medical university power savings amount to 265900 degrees. The payback period of indoor lighting in the first affiliated hospital of Chongqing medical university is 1.9 years (shadowless lamp as a result of itself particularity, the high price, less quantity, not included in energy saving) LED surgery shadowless lamp uses LED shadowless lamp as light source to replace the traditional halogen bulbs. China Led lighting manufacturers explains. Because its small volume, light structure is advantageous to the operating room air convection, and improve the operating room environment. Directional LED light source can more effective use of light source light in the course of optical design, focusing the light spot diameter required for operation. LED wants low voltage dc drive, which can easy to use battery as backup power supply, implement system trouble-free operation, ensure the safety of operation. LED shadowless lamp light efficiency is high and can reach more than 88 color. The color temperature can be adjusted between 3500 k to 5600 k, no radiation, long life, high safety, less maintenance costs. LED flat light use high brightness SMD LED chips as light source, use directional light technology combined with high pervious to light acrylic and diffusion plate of light guide plate, has high light transmission rate and higher rate of light and other characteristics. Network format design of light guide plate makes a light evenly without spots. Double side LED lamp and flat light all use the external type independent constant current drive power supply .This kind of power supply has the functions such as, high efficiency, wide input voltage range (85-265 - v), harmonic, power factor correction, open circuit, short circuit, over voltage protection. Using thermoelectric separation scheme, make the power supply has a good working environment, guarantee the power of long life and high reliability, security; The unique heat dissipation design technology and the high thermal conductivity materials make LED light source life can reach more than 30000 hours; Green environmental protection. Light source adopts the semiconductor light emitting device, do not contain heavy metals such as lead, mercury, so no pollution to the environment.
