摘要： A condensing system and method with a plurality of LEDs is disclosed. The LEDs are positioned on the same plane. A first condensing lens is disposed at front of each LED, a second condensing lens is disposed at front of each first condensing lens, a third condensing lens is disposed at front of each second condensing lens, and a fourth condensing lens is disposed at front of all the third condensing lenses. After the light emitted by each LED is condensed by the corresponding first condensing lens, second condensing lens and third condensing lens, the divergence angle of the light becomes smaller, forming a bunch of nearly parallel light beams. The bunches of nearly parallel light beams simultaneously transmit through the fourth condensing lens, and then combine. The condensing system can be used as the light source with imaging lenses disposed therebehind to form an imaging system.

摘要： A method for mixed color correction is provided. Based on the variations of the chromaticity coordinates required for adjusting between the target color and the actually-measured color, variations of illuminances of one or two of RGB of the three colors are calculated for adjusting the actually-measured color to achieve the variations of the chromaticity coordinates required for adjusting according to the correlation between the chromaticity coordinates and the tristimulus values, until the required variations of chromaticity coordinate are within a required range. This method can quickly and accurately correct and adjust the actually-measured color, guarantee the consistency of lamp colors, and is convenient for application.
