PROBLEM TO BE SOLVED: To provide a luminaire with a simple structure that improves the emission efficiency in a predetermined direction, of the light emitted from a light source.SOLUTION: A luminous module 1 includes a light guide plate 2 that guides light emitted from an LED 4 and makes the light exit from a first face 2a and a second face 2b, protective glass 3a disposed facing the first face 2a and the protective glass 3b disposed facing the second face 2b. The protective glass 3a and 3b have light transmissivity and differ in light reflectivity. |
