<P>PROBLEM TO BE SOLVED: To improve the color mixture uniformity of first color light and second color light. <P>SOLUTION: In a bulb compatible type LED lamp 100, LED light sources mounted on a substrate 2 are stored in a lamp case 5 and a cover lens 6. In the bulb compatible type LED lamp 100, a reflecting member 3 having generally cone-shaped holes at positions corresponding to the LED light sources annually arranged is disposed on the substrate 2. Translucent resin containing a first fluorescent body emitting first color light to the plurality of holes, and translucent resin containing a second fluorescent body emitting second color light are alternately injected. Particulate reflecting materials reflecting a part of the first color light and the second color light emitted from the plurality of holes to be returned to the substrate 2 side is contained in the cover lens 6. In order to reflect the first color light and the second color light which are returned to the substrate 2 side, parts between the plurality of holes of the reflecting member 3 are configured by curved surfaces. <P>COPYRIGHT: (C)2012,JPO&INPIT |
