| Title: |
Lighting System of Adjustable Color Temperature |
| Abstract: |
A lighting system capable of adjusting color temperature is provided. The
lighting system mainly comprises a light source module and a mixing
assembly. The light source module produces red-color, blue-color, and
green-color lights so as to control the color temperature of a white
light resulted from mixing the color lights. The mixing assembly is
located at a side of the light source module and comprises a first, a
second, and a third mixing device sequentially arranged along the light
transmission path. The function of the first and third mixing devices is
for light mixing by causing the lights to undergo multiple internal
reflections. The second mixing device directs the lights passing through
the first mixing device in a reverse direction (180 degrees) and enters
into the third mixing device.
