<P>PROBLEM TO BE SOLVED: To provide a light emitting diode lamp in which safety is secured. <P>SOLUTION: A light emitting diode lamp includes: two first pins 61, 62 which are provided at one end thereof; two second pins 63, 64 which are provided at the other end thereof; a light emitting diode module part 1 which is provided at the middle thereof; and a circuit connecting at least two of the two first pins and the two second pins to the light emitting diode module part. The light emitting diode lamp includes a protection circuit part provided with a fuse 5 to protect the light emitting diode module part at the time of generation of a high voltage. The protection circuit part further includes: rectifier diodes 2 which are respectively mounted to one of the two first pins and one of the two second pins in a forward direction; transient voltage suppression diodes 3 which respectively connect between the two first pins and between the two second pins; and bridge diodes 4 which respectively connect between the two first pins and between the two second pins in a state of non-polarity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
