Lighting system with lens-retaining structure

Abstract

A lighting system utilizing light-emitting diodes (LEDs) and methods for configuring lanterns thereof are disclosed. The lantern includes a roof or canopy that includes fans that span directly between the electronics and LEDs for improved heat dissipation, the fans preferably formed integral with the canopy. The LEDs are mounted on easily mounted and removed modular printed circuit boards, in at least two different sizes and numbers of LEDs, and optical lenses of at least two different lighting patterns are provided, so that the lantern may be assembled or retrofit according to a desired application including candlepower and lighting pattern for cast light. The optical lenses are individually provided, utilize refraction to diminish reflection, and, in one form, incorporate an integral reflector to assist in defining a lighting pattern. In some forms, a securement may be provided for individual securement of lenses with the PCB.
