Abstract:
A blended color lighting module, comprising a blue LED light source (101), a green LED light source (103), a red LED light source (105), a blue excitation light source (107), a first beam combining device (109), a second beam combining device (110), and a fluorescent powder layer provided on the surface of the green LED light source (103). Joint effects of a switch signal generating device (200) and of a light source driving device (100) are utilized to control the blue LED light source (101), the green LED light source (103), the red LED light source (105), and the blue excitation light source (107) to time-divisionally generate correspondingly a blue LED light beam and/or a green LED light beam and/or a red LED light beam and/or a blue excitation light beam. The output of the blended color lighting module always presents a green fluorescent light beam blended into the blue LED light beam and/or the red LED light beam, thus enriching light source colors, and enhancing lighting light source brightness.
