Abstract: An LED lighting system capable of performing a dimming function for adjusting brightness of output light to decrease includes: an LED light source comprising three or more LED channels that are respectively configured to emit light of different color temperatures; and an electric circuit configured to electrically drive the three or more LED channels. The electric circuit is configured to drive the three or more LED channels so that brightness and color temperature of the output light obtained by the LED light source decrease together in conjunction with each other during dimming in which the brightness of the output light decreases.

Abstract: The lamp comprises a light source configured to emit light, a support structure that supports the light source, and an optical component designed to change the characteristics of the light emitted from the light source. The support structure is configured to rotate both the light source and the optical component about a first axis, and the light source and the optical component are designed to move linearly relative to each other along a second axis.
