<P>PROBLEM TO BE SOLVED: To provide a lamp which is restrained in reduction of a quantity of light in a light-emitting direction caused by existence of a circuit unit as much as possible, in the lamp with a structure wherein the circuit unit is arranged in a globe. <P>SOLUTION: In the lamp 1, an LED module 3 and the circuit unit 9 are stored in an envelope including the globe 7 and a base 11. The LED module 3 is arranged in a posture where an emitting direction of light is faced to a direction opposite to the base 11, and the circuit unit 9 is arranged at a side of the LED module 3 opposite to the base 11. The globe 7 has diffuse reflectance, and its diffuse reflectance becomes lower from a base end part 7c to a tip end part 7a of the globe 7. <P>COPYRIGHT: (C)2012,JPO&INPIT |
