25 September 2014 Lightweight LED Fluorescent lamp using engineering poly carbonate
Author Affiliations +
In this study, we developed lightweight LED fluorescent lamp using thermally conductive engineering PC a heat sink instead of metal. In order to secure price competitiveness, we used double extrusion molding which extrude both the heat sink plate and diffuser plate simultaneously. Fabricated fluorescent lamp has less than 20% of weight as compare to glass fluorescent lamp and power consumption is 20.2 watts, luminous efficiency 123.9 lm/W, respectively. Despite the heat conductive plastic is adopted, the system temperature is maintained less than 35℃ and the thermal resistance is 25 ℃/W.
