<P>PROBLEM TO BE SOLVED: To provide a light emitting device and its light guide member for reproducing light emitting effect of a conventional light bulb by using an LED light source. <P>SOLUTION: The light emitting device includes a light guide member and an LED light source. The light guide member includes a reflection surface, a first refraction surface, and a second refraction surface. A first part of light emitted from the LED light source is reflected by the reflection surface and refracted by the first refraction surface to form a first virtual image in the light guide member. Moreover, a second part of light emitted from the LED light source is reflected by the reflection surface and refracted by the second refraction surface to form a second virtual image in the light guide member. <P>COPYRIGHT: (C)2010,JPO&INPIT |
