<P>PROBLEM TO BE SOLVED: To provide an LED bulb enabled to irradiate downward and capable of obtaining efficient light distribution, even in case one is attached aslant or sideways. <P>SOLUTION: A base 27 is mounted on a socket 52 in rotation, by which, power is supplied to a power source device 23, and the LED 26 mounted on an LED substrate 25 is lit on. At that time, since the LED substrate 25 mounting the LED 26 and an opening 221 fitted to a body 22 are arranged in a slanted direction to a rotation center CL of the base 27, downward irradiation is possible even in case the LED bulb 10 is mounted aslant, hence, efficient light distribution. <P>COPYRIGHT: (C)2012,JPO&INPIT |
