摘要 |
A luminaire (L) includes a plurality of light-emitting elements (LED (2)), and an optical member (3). The optical member (3) is formed a refractive area (3b1R, 3b2R, 3b3R) of a Fresnel lens (3b1, 3b2, 3b3) for each of the light-emitting elements individually and a reflective area (3b1L, 3b2L, 3b3L) of the Fresnel lens (3b1, 3b2, 3b3) between the refractive areas. |
