LED lamp capable of free color temperature conversion and color temperature conversion method of LED lamp using the same

摘要

The present invention relates to an LED lamp capable of freely converting color temperature and a color temperature conversion method of an LED lamp using the LED lamp, and includes a monochromatic light or white light LED, a fixed filter, and a movable filter for color temperature conversion. By configuring the overlapping region of the color temperature conversion movable filter with respect to the fixed filter so that it can be gradually and reversibly expanded and reduced, the user can realize illumination light having a desired color temperature and color rendering property. It can be used and has high convenience and economy. [Selection] Figure 1
