Abstract

The invention discloses a multi-channel LED geometric light mixing method. The method includes the following steps: Step 1. After selecting four LEDs, draw the largest external triangle in the CIE chromaticity coordinate system and connect the fourth point in the middle Form a connection line with one of the vertices; step 2, take a certain point on the connection line; step 3, in the coordinate system, calculate the proportional relationship between the points according to the length of the line segment between the coordinate points, and finally get The light radiation power ratio of each LED at a certain target light color point. The method can accurately design the power ratio of each LED in the mixed light of multiple LEDs, can accurately realize any light color required by black body radiation or sunlight curve, meets design requirements, and improves the lighting quality of LED lamps.

Description

technical field [0001] The invention relates to the technical field of application of LED lamps, in particular to a multi-channel LED geometric light mixing method. Background technique [0002] With the continuous expansion of the application field of LED lamps, there is an increasing demand for dimming and color-tuning LED lamps. Especially in some special places, strict requirements are put forward for optical parameters such as brightness, color temperature, and color rendering of LED lamps. For example, LED lamps are required to be able to simulate the change of natural light color and so on. [0003] In the design of dimming and toning LED lamps, there are many ways to realize dimming and toning. However, the general principles are similar, and multiple LEDs with different color temperatures are used as light sources, and the light is mixed according to different proportions, so that the mixed light color meets the design requirements. Although the principles are si...
