The HS-HB1504-75W LED high bays
from Liangfeng Lighting put great emphasis on thermal management with the specially designed heat sink. The rugged, die-cast aluminum housing consists of a driver compartment and a plurality of heat dissipating fins with a large surface area to to facilitate more efficient dissipation into the ambient. The effective removal of thermal energy from the semiconductor junction and surrounding structure allows the LEDs to be driven at higher power levels without suffering degradation of materials utilized in the LED, such as phosphor or encapsulate, which eventually impacts both the life and intensity of the LEDs. Coupled with the high efficiency Philips Xitanium driver, the high performance Lumileds/Nichia LED light engines used in HS-HB1504-75W deliver a minimum of 155 lumens per watt for maximum efficacy in high-bay applications. The high bay fixture is designed with multiple photometric distributions of 45°, 60°, 80°, 90° and 120°to accommodate a range of industrial, commercial, manufacturing, gymnasium and other applications where exceptional optical performance and light distribution coverage are critical. The HS-HB1504-75W high bays are compatible with 1-10V/Dali dimming systems, motion sensors and Zigbee control.
