A lighting system for providing uniform bright lighting of products within in a glass door refrigerated cabinet. The lighting system has a frame member with an angled wing extending therefrom that wraps around a side edge of a light-transmitting optical shield, and a LED lighting strip positioned between the frame member and the optical shield. The LED lighting strip has a plurality of spaced-apart LED lights mounted therealong with a coined reflective facet optic mounted around each LED light. The angled wing(s) reflects light emitted laterally outwards from the at least one LED lighting strip such that the light can be re-directed to evenly illuminate products in a refrigerated cabinet. The angled wing(s) also protects a user's fingers from cracking the plastic optical shield which can become brittle in the cool or cold temperatures of the refrigerated cabinet.

A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.
