    • PROBLEM TO BE SOLVED: To provide a luminaire capable of improving brightness feeling by widening a distribution range of light emitted from a light source unit.SOLUTION: A luminaire of an embodiment includes an apparatus body 1, a light source unit 2, and a cover member 4. The light source unit 2 is disposed in the apparatus body 1 and includes a light-emitting element 22 as a light source. The cover member 4 has translucency and diffusing properties, is formed so as to project from a front side edge portion 11b1, 12b1 of the apparatus body 1, includes a side wall 4a extending along the edge portion 11b1, 12b1 and formed upright within a range of inner angle from 60° to 90° with reference to a horizontal plane at least partly along the edge portion, and covers the light source unit 2 so as to leave a substantially center portion of the apparatus body 1 as an uncovered portion 13.
    • 要解决的问题:提供一种能够通过加宽从光源单元发射的光的分布范围来改善亮度感的照明器。 解决方案:实施例的照明装置包括装置主体1,光源单元2和盖构件4.光源单元2设置在装置主体1中,并且包括发光元件22作为 光源。 盖构件4具有半透明性和扩散性,形成为从设备主体1的前侧缘部11b1,12b1突出,具有沿着边缘部11b1,12b1延伸的侧壁4a, 相对于至少部分沿着边缘部分的水平面,内角为60°至90°,并且覆盖光源单元2,以便将设备主体1的基本中心部分留作未覆盖部分13。 P>版权所有(C)2013,JPO&INPIT
