Overview of LED lighting for refrigerated display merchandisers.

Author(s) : ANDERSON T. D.

Summary

Conventional fluorescent lighting used to illuminate products within refrigerated merchandisers can account for as much as 30% of the energy consumed by a case. Solid-state lighting using LEDs presents a substantial opportunity to reduce both direct electrical and indirect power consumption (i.e. load capacity) of commercial refrigerated display merchandisers. The transition from linear T-8 fluorescent lamps to LED luminaires is not straightforward and requires careful consideration of a number of criteria when designing or implementing solid-state lighting fixtures into display merchandisers. These factors include the directionality and usable light of an LED luminaire, thermal management of the LED lamps, power supplies (drivers), correlated colour temperature, colour quality, useful life of the luminaire, and dimming control of the light output. This report looks at these factors and their effect on design and selection of LED luminaires.
