PROBLEM TO BE SOLVED: To provide an on-vehicle LED lamp enabled to light on/out a light source and to change the illumination intensity and color temperature of the light source by the motion of a hand.SOLUTION: An LED lamp 1 comprises: a light source part 2 having an LED as a light source; a detector 3 for detecting the action of a hand in a detection area to output a signal; and a control part 4 for controlling the lighting of said light source part 2 by a signal outputted from said detector 3. Said control part 4 lights on/off said light source part 2 when the hand shades the detection area, and said control part 4 changes the color temperature of an outgoing beam from said light source part 2, when the hand is turned in the detection area, and changes the illumination intensity of the outgoing beam from said light source part 2 when the hand is moved up and down in the detection area. |
