<P>PROBLEM TO BE SOLVED: To provide an LED lighting apparatus capable of changing brightness and color temperature with a simple structure. <P>SOLUTION: The LED lighting apparatus includes an LED module 100 with an LED chip A120a having an input terminal 121a and an output terminal 122a as well as an input-side conductor pattern 111a and an output-side conductor pattern 111b on a mounting surface 102, a ring member 300 arranged to surround a periphery of the LED module 100 with a ring inner peripheral surface 320 and having a spring 200 with conductivity protruded from the ring inner peripheral surface 320, and a guide housing an edge of the ring inner peripheral surface 320 so as for the ring member 300 to turn around the LED module 100. When the spring 200 is arranged at a first position P10 as the ring member 300 turns along the guide, the spring comes in contact to conduct with the input-side conductor pattern 111a and the output-side conductor pattern 111b, the input terminal 121a and the output terminal 122a are short-circuited so as to turn off light of the LED chip A120a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
