HIGH-PERFORMANCE HIGH-POWER LED LIGHTING SYSTEMS AND METHODS THEREOF

摘要

A Light-Emitting Diode (LED) light apparatus has a housing and a printed circuit board (PCB) received in the housing. The PCB has one or more first openings and one or more LEDs on a front side thereof about the first openings. The housing has a rear-wall structure with a plurality of fins spaced from each other and one or more second openings at locations corresponding to those of the first openings for heat management. The LED light apparatus may also have a plurality of rotatable LED panels having PCBs and LEDs thereon. The LED panels are spaced from each other with gaps therebetween for heat management, and are rotatable for controlling light distribution, light angular-span, and light direction. A LED grow-light system uses a light-distribution structure such as reflectors and/or fiber-optic cables for distributing at least a portion of the light towards the plant.
