摘要

本論文係以低成本可回收之PLA塑料，作為環保LED固態照明球泡燈的燈殼，以取代傳統球泡燈之金屬燈殼。本文以公規E27接頭來製作，其製作過程皆以保護環境為製作理念。透過繪圖軟體來繪製其燈殼，把環氧樹脂混和石墨粉並批覆在PLA燈殼表面做散熱處理，此外並以迷你風扇來移除LED發光源產生之餘熱。本研究發現，在有加裝迷你風扇的模組下，8W LED球泡燈的散熱機構在環氧樹脂混合石墨粉比例以2:1為較佳，其螢光膠體表面平均溫度僅102.07℃。最後PLA具有成本低、輕巧及環保可回收等優勢，其在生產過程也是無毒的，並定位於中、高功率LED燈具，材料成本僅市售LED球泡燈具的30%，具有市場競爭力。

In this thesis, the light shell of a solid-state LED light bulb was made by the low-cost recyclable polylactide (PLA) plastics. It was used to replace the current widely used shell made by the metal. The standard of electric head is the formal E27. The concept here obeys that the process should protect the environment. The lamp envelope was drawn by using the graphics software. In order to do the heat treatment, the graphite powder was mixed into epoxy the resin and covered onto the housing surface of the PLA lamp. In addition, a mini fan was adapted to remove heat generated from the LED light source. It was found that in the installation of mini-fan modules, the best cooling mechanism of a 8W LED bulb has an epoxy resin mixed graphite powder ratio of 2:1. The average surface temperature of the fluorescent colloid was only at 102.07 ℃. Finally, PLA has a low cost, light weight, recyclable and environmental advantages, it is non-toxic in the production process, and located in the high power LED lamps, the material cost is only 30% of commercially available LED bulb lamps, with market competitiveness.
