Abstract
An illumination lamp () includes at least one solid-state lighting member () for radiating light, and a lampshade () being arranged corresponding to the at least one solid-state lighting member. The lampshade includes an array of lenses (). Each lens has an incidence surface () for incidence of the light into the lampshade, and an opposite emitting surface () 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 () 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.
