New Cooling Design and Analysis for Park-Garden Lighting Fixtures
Abstract
New lighting technologies make life easier and promise to better lighting conditions.
However, when luminaires aren't planned properly, the lifetime of the luminaire can be
shorter than expected. Increasing efficiency of LED technology helped LED's to having
more space in our lives with lighting. LED manufacturers say that their LED's have
50.000-60.000 hours lifespan with test reports. But, these tests were performed under
specific temperature conditions. Therefore, when designing luminaires and LED
modules, LED heatsink must provide these conditions. In this study, a new generation
LED based park-garden lighting fixture cooler body was designed. This design (LED
luminaire) can replace compact fluorecent lamp based fixtures operate on principle of
direct lighting up to 100W and 70, 100, 150W metal halide based fixtures which operate
on indirect lighting principle. Also this new design and LED based luminaire will save
40-60% energy.
