Compensation light mixing method of adjustable color temperature lamp

Abstract

The application provides a compensation light mixing method of a color temperature adjustable lamp, and relates to the technical field of illumination control, and comprises the following steps: in a factory detection stage, a first LED lamp string and a second LED lamp string are caused to emit light together at a middle color temperature grade, a compensation LED lamp string is not connected, and a basic light mixing color point is detected; the compensation LED lamp string is connected in at least two candidate compensation states, and a compensation light mixing color point is detected; a target compensation grade is determined according to the basic light mixing color point, the compensation light mixing color point and a black body locus reference point; the target compensation grade is solidified as a compensation connection parameter; and in a use stage, a switching unit controls the compensation LED lamp string to be connected to a current loop according to the compensation connection parameter. According to the method, the compensation connection parameter can be determined according to the factory detection result, and the light color consistency at multiple color temperature grades is improved.
