PROBLEM TO BE SOLVED: To provide a luminaire which achieves high efficiency in extraction of light flux emitted from light emitting elements.SOLUTION: A luminaire uses semiconductor light-emitting elements as light sources and has a translucent cover member which integrally covers a substrate and the semiconductor light-emitting elements mounted on a substrate surface. A shape of a portion covering the semiconductor light-emitting elements is formed into a hemispherical shape in which the semiconductor light-emitting elements are located at a substantially center thereof.SELECTED DRAWING: Figure 2 |
