“…There are several aspects having been studied in heat dissipation, such as package design [1][2][3][4], thermal interface material [5], low thermal resistance heat sink material [6][7][8][9], and cooling systems [10][11][12][13][14]. The best-known devices for effective heat transfer or heat spreading with the lowest thermal resistance are heat pipes with vapor chambers which are two-phase heat transfer devices with excellent heat spreading and heat transfer characteristics [15,16].…”

“…This structure gives the junction between the LED chip and metal PCB, which is formed by soldering, a large thermal resistance, so heat that is generated by the chip is rapidly transferred to the heat sink, but this heat transfer is limited by the die attachments and thermal conductivity grease, each of which have a high thermal resistance. Several recent studies have tried to improve the thermal conductivity of the base substrates by using alumina ceramic, AlN ceramic, silicon and Al metal PCB [8][9][10][11]. Several studies have reported noticeable improvements in the performance of LED s when ceramics with high thermal-conductivity are used to coat substrates [12][13][14][15].…”

“…Tasarımdan aldıkları simetrik çeyrek için MATLAB kullanarak analitik çözüm yapmışlar ve ısı dağılım grafiklerini elde etmişlerdir. Sonuç olarak çoklu LED paketleme yöntemi ile optimum dizilime sahip bir armatürün ısıl dağılım farkının, tek tip LED armatürlere göre çok daha düşük olacağını ortaya koymuşlardır [6] . Nuttall ve arkadaşları (2008) yaptıkları çalışmada tüm yönleriyle bir LED yol aydınlatma sistemi tasarlamışlardır.…”
