PROBLEM TO BE SOLVED: To provide a lamp capable of restraining unevenness of brightness.SOLUTION: A lamp 11 in an embodiment comprises plural light emitting parts that have two kinds of light emitting elements 45a, 45b aligned on a substrate 21 in a predetermined direction, that emit light with different colors, and that can independently control a flux of the emitted light. Also, the lamp 11 in an embodiment comprises a pipe 12 formed to include a translucent material that diffuses the light emitted by the light emitting elements 45a, 45b and whose linear transmissivity is any value from 0% to 50%. In the lamp 11 in an embodiment, a distance a between light emitting elements 45a with the same kind for emitting light with the same color between the different light emitting parts 45 is smaller than an inside diameter r of the pipe 12, and a distance d from a lower part of the pipe 12 to the light emitting elements 45a, 45b is larger than an inside radius (r/2) of the pipe 12. |
