<P>PROBLEM TO BE SOLVED: To provide a lamp capable of efficiently taking out light from a light source to the outside without enlarging an outer diameter of the lamp. <P>SOLUTION: A lamp envelope of the lamp 1 consists of a globe 2, a holder 3, and a case 5 arranged between the holder 3 and a base 4. An LED module 6 as a light source is arranged on the surface of the holder 3 faced inside the globe 2. A lighting-up circuit board 8 mounting a group of circuit elements 8b is held in the globe 2 in erection against the light source with a resin holding member 7. The lighting-up circuit board 8 is arranged so as to make the light source viewed through a gap of the group of circuit elements 8b mounted on the lighting-up circuit board 8, when the LED module 6 is viewed from a globe 2 side in a direction orthogonal to the LED module 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
