Abstract: The present invention relates to a lens (100) for an illumination device (200). The illumination device (200) is particularly designed as a light box which comprises a lamp cover (4), a lens (100) arranged on the bottom surface (41) of the lamp cover (4), and a light source (5) arranged in the accommodation cavity of the lens (100). As can be seen from the figure, the light emerging from the lens (100) all illuminates the region to be illuminated of the side surface (43) of the lamp cover (4), and no light goes to the top surface (42) opposite to the bottom surface (41).

Abstract: Various embodiments may relate to a lens for an illumination device, including an incident surface, an emergent surface, and a reflective surface connected between the incident surface and the emergent surface. The lens includes a first axis as an optical axis of the lens, a second axis perpendicular to the first axis and extending in a longitudinal direction of the lens, the first axis and the second axis defining a symmetrical surface of the lens, and a third axis perpendicular to the symmetrical surface, a first portion of light from a light source is incident upon the incident surface, refracted by the emergent surface, and then emerges to form a first light beam, and a second portion of light from the light source is incident upon the incident surface, reflected by the reflective surface, refracted by the emergent surface, and then emerges to form a second light beam.
