Abstract:
A lighting fixture with reduced glare is provided. Lighting fixtures described herein use a lens assembly to redirect light away from a housing in order to reduce a unified glaring ratio (UGR) (e.g., when viewed crosswise or endwise). The lens assembly may further provide diffusive properties which result in a more pleasing and soft light over traditional lighting fixtures. In aspects described herein, the UGR of troffer-style lighting fixtures can be improved (e.g., reduced) through lens assemblies having one or more light redirection features configured to particularly redirect light emitted at high v-angles (e.g., light emitted sideways relative to the housing at v-angles greater than 70 degrees). For example, the lens assembly may include an inner prismatic surface of a lens, an inner lens, a louver assembly (e.g., over or under a lens), or a reflector to achieve this light redirection.
