Color-temperature-adjustable integrated large-power LED medical illumination chip

Abstract

An integrated large-power LED medical illumination chip can be used for medical operation illumination, medical examination illumination as well as integral illumination in an operation room as a color-temperature-adjustable light source. The integrated large-power LED medical illumination chip mainly comprises LED tube cores, a base plate, a heat dissipating plate, a power supply adapting wire and an LED driving controller. Different colors of LED tube cores are integrated on the base plate of a circuit board according to a certain array, and the base plate is connected to the heat dissipating plate. The LED tube cores in the integrated chip are separated into multiple groups according to colors and separately powered. The brightness of the LED tube cores with various colors can be independently regulated. Through regulating the color mixing ratio of different colors of LED tube core strings, the integrated large-power LED chip can be regulated to have any color temperature and brightness in a range of 3500K to 6500K. The integrated large-power LED medical illumination chip can be used for illumination in environments with special color temperature requirements, such as the operation room and an examination room, is particularly suitable for medical illumination and the like, and is favorable to improving medical illumination quality and reducing medical accidents.

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 ...

AI Technical Summary

Problems solved by technology

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 difference is large, the volume is large, and it cannot meet the requirements of vertical and horizontal air laminar flow. Used in high-demand clean operating rooms, etc., low lighting quality affects doctors' identification of tissues
