New Cooling Design and Analysis for Park-Garden Lighting Fixtures

<span style="font-size: 12.6px; font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif;">Yeni aydinlatma teknolojileri hayati kolaylastirir ve daha iyi aydinlatma kosullari vaat eder. Ancak dogru planlanmadiginda aydinlatma elemanlarinin kullanim ömürleri beklenenden daha kisa olabilir. LED teknolojinde artan verim, aydinlatma ile birlikte hayatimizda daha çok yer edinmeye baslamasina yardimci olmustur. LED teknolojisinde LED üreticileri 50.000-60.000 saate kadar kullanim ömrü oldugunu testlerle belgeler. Ancak bu testler belirli sicaklik kosullarinda gerçeklestirilmistir. Bu sebeple armatür tasarlanirken sogutucu gövde bu kosullari LED modül ve LED’e saglamalidir. Bu çalismada hali hazirda park-bahçe aydinlatmalarinda kullanilan dogrudan aydinlatma prensibinden çalisan, çogunlukla düsük verim 100 W’a kadar kompakt floresan lambali ve endirekt aydinlatma prensibinde çalisan 70, 100, 150 W metal halide isik kaynakli armatürlerin yerine geçebilecek ve bu ürünlere göre %40-60 enerji tasarrufu saglayacak yeni nesil LED isik kaynakli bir park-bahçe armatürünün sogutucu gövdesi tasarlanmistir. </span><span style="font-size: 12.6px; font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif;">New lighting technologies make life easier and promise to better lighting conditions. However, when luminaires aren&#39;t planned properly, the lifetime of the luminaire can be shorter than expected. Increasing efficiency of LED technology helped LED&#39;s to having more space in our lives with lighting. LED manufacturers say that their LED&#39;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.
