Abstract

A lens cover for a plurality of light emitting devices is provided. The lens cover includes a substrate and an optical lens element. An optical lens element extends from the substrate and defines a focus center. The optical lens element includes a length and a width, and includes an outer surface and an inner surface. The outer surface extends from the substrate along the outer periphery and is centrosymmetric with respect to the focal point. The inner surface is centrosymmetric relative to the focal point.

Description

technical field [0001] The apparatus described below generally relates to a light fixture comprising an array of light sources for illuminating an indoor growing facility. Each light source includes a light emitting diode (LED), a lens cover, an encapsulant material disposed between the LED and the lens cover, and a protective coating disposed on the outer surface of the lens cover. Background technique [0002] Indoor growing facilities, such as greenhouses, include lamps that provide artificial lighting for plants to encourage growth. Each of these light fixtures typically includes multiple LEDs that generate artificial light for the plants. However, the environment within these indoor growing facilities may contain different types of gaseous and / or airborne fluid particles that can cause the optical quality of the LEDs to degrade (e.g., yellow) over time. SUMMARY OF THE INVENTION [0003] According to one aspect of the present disclosure, a lens cover for a plurality ...
