<p>The present invention provides an LED lamp which has a simple circuit configuration and is capable of emitting light with a low color temperature as well as sensing light like a light bulb. The LED lamp, which receives an input DC current of a size varied by a light modulation operation to be lit, includes: a first LED; and a second LED (20) which emits light at a lower color temperature than the first LED (18); and an impedance circuit which is connected to the first LED(18) in parallel and to the second LED (20) in series.</p> |
