<P>PROBLEM TO BE SOLVED: To provide an intelligent and energy saving LED lamp having a low light and total light emission. <P>SOLUTION: The LED lamp has a lamp base 11 and a lamp head 111 at the bottom end of the lamp base, and an LED substrate 14 is installed inside the lamp base, while a plurality of LEDs 141 are installed at the top end. An infrared sensor 13 is installed inside the lamp base and an infrared sensor head 131 is installed at the top end. A lamp cap 15 is combined to the top end of the lamp base and a projecting cap 152 corresponding to the infrared sensor head is installed at the outer end face of the lamp cap. When the light of the outside environment is perceived sufficiently, the LEDs do not emit light, and when the light of the outside environment is insufficient and the infrared sensor head does not perceive movement of an object, the LEDs emit a prescribed light, whereas, when the light of the outside environment is insufficient and the infrared head perceives movement of the object, the LEDs emit total light. <P>COPYRIGHT: (C)2013,JPO&INPIT |
