MODULAR STEPPED REFLECTOR

摘要

Provided herein are optical reflectors having a plurality of specially designed reflective surfaces and geometrical arrangement to provide improved illumination of a target area. Also provided are related methods for growing plants with the optical reflectors described herein. The reflective surfaces provde substantially normally aligned light over the entire target area, thereby minimizing shading issues of conventional optical reflectors. Also disclosed herein are efficient cooling by air and/or fluid that can substantially reduce cooling requirements by conventional air conditioning with attendant power savings.
