    • An illumination lamp (40) includes at least one solid-state lighting member (41) for radiating light, and a lampshade (10) being arranged corresponding to the at least one solid-state lighting member. The lampshade includes an array of lenses (11). Each lens has an incidence surface (110) for incidence of the light into the lampshade, and an opposite emitting surface (112) for emission of the light from the lampshade into ambient. At least one of the incidence surface and the emitting surface is a concave surface. The concave surface extends along a first direction. At least one micro-structure (111) is formed on the concave surface. The at least one micro-structure is long and narrow, and extends along the first direction. The micro-structure is configured for increasing radiating area of the light entering into the lampshade along a second direction intersecting the first direction.
    • 照明灯(40)包括用于照射光的至少一个固态照明部件(41)和对应于该至少一个固态照明部件设置的灯罩(10)。 灯罩包括一组透镜(11)。 每个透镜具有用于将光入射到灯罩中的入射表面(110),以及用于将来自灯罩的光发射到环境中的相对的发射表面(112)。 入射面和发射表面中的至少一个是凹面。 凹面沿着第一方向延伸。 在凹面上形成至少一个微结构(111)。 所述至少一个微结构是长而窄的并且沿着所述第一方向延伸。 微结构被配置为沿着与第一方向相交的第二方向增加进入灯罩的光的辐射面积。
