自從愛迪生發明改良燈泡後，人類開始脫離了煤油燈、蠟燭燈，也才開始研究各種電力設備，鋪設各種電力措施，到後面直流電、交流電的互相探討。讓人類的科技因為有電，而進入了另一個時代。
電器相關的一切都是因為電的產生，而電是因為燈泡的發明被重視。如果要說電燈做為人類電器的始祖產品也不為過。大約的統計數據顯示全球用電量約有25%是用在了照明設備上。
因應每個地區，或是同地區但不同國家的住家裝修風格不一，使得燈飾在燈泡發明後100多年的今天，各地都有一套獨特的代表性燈飾或風格，像是美國大多的吊燈偏大，喜歡用長管做為連接件，英國則是喜歡用吊鍊做為連接件，且燈體因為房屋的關係較為小型，日本則不喜歡吊燈型的風格，因為日本較易發生地震的關係，反而喜歡使用吸頂燈，且材料一定要是塑膠的，避免因為地震的關係而掉落砸傷人。
各地不同的喜愛尺寸，安裝方式、喜好材料、顏色的變化都使得燈飾有了更多元的面貌，但這一層關係後來也導致了燈飾在2010年時過多的競爭者使得市場上充斥著過多的款式供客戶進行挑選，導致無法達到真正的量產化。
本研究就燈飾各時代的演變來說明燈飾製造業所遇到的困難，並以直昌燈飾為例，探索傳統燈飾廠商如何研擬適當策略並且著手轉型，以突破這些困難，最後達到永續經營的目標。本研究的發現對於同處於燈飾行業的其他廠商，應可給予建議，並有借鑑的價值。

Even since Thomas Edison triumphed over the gas industry by introducing his electric light bulb and establishing his system of electric lighting, the landscape of the lighting of homes and offices transformed dramatically from gas lights into electric lights. Meanwhile, the establishment and triumph of the electric lighting opened the door for the lighting industry to emerge. Nowadays, statistically speaking, about 25% of global electricity usage is for lighting equipment.
The huge demand for different styles of home decoration and installation methods in different countries attracted companies to enter the lighting industry, resulting in tons of different product choices on the market and fierce competitive pressures in the industry since 2010. The multiple product lines also make it hard for those firms to enjoy the benefits of economies of scale.
This study aims to explore the different challenges faced by the lighting industry in the evolution of the industry by a case study of Strength Grand Lighting. By examining how Strength Grand Lighting responded to those challenges in different time periods and achieved sustainable growth, this study provides insight into the strategies the lighting company can employ to overcome those challenges and achieve sustainable growth.
