Problems solved by technology

In addition, the selection of illumination light having a desired color temperature and color rendering is limited to preset values, and white LEDs are used, so there are problems in that it makes it difficult to control the uniform dispersion of fluorescent substances as described above, and Reduced lifespan of LED lamps due to reduced heat dissipation characteristics due to phosphor coating on monochromatic LEDs

Abstract

The present invention relates to an LED lamp capable of freely changing color temperature, and an LED lamp color temperature changing method using same, the LED lamp comprising a monochromatic- or white-light LED, a fixed filter, and a variable filter for color temperature changes, and being configured to enable gradual and reversible expansion and reduction of the overlap area of the variable filter for color temperature changing with respect to the fixed filter such that an illumination light, which has a color temperature and a color rendering property desired by a user, can be implemented, thereby being highly convenient of use and economical.

Description

technical field [0001] The disclosure of the present invention relates to an LED (Light Emitting Diode) lamp capable of freely converting color temperature and a method for converting color temperature using the LED lamp, and more particularly relates to an LED lamp capable of freely converting color temperature, the LED lamp comprising a single color or white LED, fixed filter ( ) and movable filter ( ), and the LED lamp can gradually and reversibly expand / decrease the overlapping area (overlap) between the fixed filter and the movable filter, so that the user can achieve the desired color temperature and color rendering according to the atmosphere or situation Permanent illumination light, and relates to a method for converting color temperature using the LED lamp. Background technique [0002] LEDs exhibit high light conversion efficiency and low power consumption, have a semi-permanent lifetime and high response speed, and are suitable for size and weight reduction. ...
