Abstract

Abstract

Lighting heat gain is a major contributor to the space cooling load in a buildings and it is necessary to determine the lighting heat gain distribution specifically the fractions of convective heat gain, radiative heat gain, conditioned space heat gain, and plenum space heat gain. Traditional lighting heat gain distribution has been determined and the data is available on the ASHRAE Handbook. However, there is a lack of relevant data for the LED lighting heat gain. As the LED lighting fixtures are an emerging lighting technology, the need to identify LED lighting heat gain becomes highly demanded. In this project, fourteen LED lighting luminaries’ heat gain distributions were determined through systematically designed experiments. Specifically, the split between the convective heat gain and the radiative heat gain, and the split between the conditioned space heat gain and ceiling plenum heat gain (if applicable) were determined. This paper describes the approach and official test for determining the LED heat gains.
