Abstract

The invention provides an integrated large-power LED medical illumination chip which can be used as a light source with adjustable color temperature for medical operating illumination, inspection illumination, and whole illumination in an operating room; the chip mainly comprises an LED tube core, a substrate, a heat dissipation plate, a power switchover line and an LED driving controller; LED tube cores with different colors are integrated on the substrate of a circuit board by a certain array; the substrate is connected on the heat dissipation plate; according to different colors of LED tube cores, the integrated chip is divided into a plurality of groups which are used for power supply respectively. Brightness of various colors can be adjusted independently, the integrated large power LED chip can be adjusted in the range of 3500K-6500K to have any color temperature and brightness according to the mixed color proportion of the LED tube core series of different colors, the chip can be used for illumination in operating rooms, inspection rooms, environment with special color temperature requirement and the like, is especially applicable for medical illumination and the like, and is beneficial for improving the medical illumination quality and reducing the medical negligence.

Description

technical field [0001] The invention relates to a light source, especially an integrated high-power LED medical lighting chip with adjustable color temperature used as a light source in medical lighting, which is most suitable for operation, inspection lighting and overall medical lighting in operating rooms and examination rooms used as a light source. Background technique [0002] Lighting sources are routine and necessary equipment in hospitals, and the use of medical lighting systems is a necessary working condition and prerequisite for many medical work. At present, the shadowless lamp and examination lamp used in the operating room of the hospital are composed of an umbrella-shaped lamp housing and a group of halogen bulbs to form a lamp head as a whole. It has some design and application problems, such as the color temperature cannot be adjusted, the temperature rise is too high, the brightness of the central spot is uneven, the power consumption is large, the color ...
