Abstract

See full text

A light-guiding cover includes a light input surface defining a central axis and a light output surface. The light-guiding cover has a reflecting portion formed therein and substantially symmetrical about the central axis. The reflecting portion surrounding the central axis has an outer reflecting surface and an inner reflecting surface. The light input surface is defined into two regions, an inner region and an outer region, by the reflecting portion. The outer reflecting surface of the reflecting portion is arranged away from the central axis, the inner reflecting surface of the reflecting portion is arranged near to the central axis. Thus, the light-guiding cover of the instant disclosure can guide the light beams emanated from a LED to travel in certain optical paths and provide uniformly distributed lighting. Moreover, the instant disclosure also provides an illumination device having the light-guiding cover that can omni-directionally illuminate.
