2017年LED照明降低5.7億噸碳排放

作者 : Dylan McGrath

根據IHS Markit的最新調查報告,2017年,LED用於建築物照明和室外照明減少了大約 5.7億噸的二氧化碳(CO2)排放量。

相較於傳統的白熾燈和螢光燈,發光二極體(LED)的效率是該技術最受歡迎的優點之一。根據IHS Markit的最新調查報告,2017年,LED用於建築物照明和室外照明減少了大約 5.7億噸的二氧化碳(CO2)排放量。

在 2017 年在產生同樣亮度的情況下,LED 的平均消耗功率分別比螢光燈和白熾燈少 40% 和 80%。

市場研究機構IHS Markit估計,所減少的排放量大約相當於162座燃煤電廠,讓LED元件和照明公司在2017年大約減少了1.5%的全球碳足跡。

IHS Markit照明和LED部門首席分析師Jamie Fox認為,LED有助於LED元件和照明公司促進其產業轉型。他說,這些公司「較其他產業更能夠有效率地面對氣候變化問題,因而應該給予支持。」

Fox補充說:「相較於其他產業,LED公司的員工更能實在地說,透過銷售更多的產品,他們協助了減緩全球暖化的問題。」

Fox指出,在產生同樣亮度的情況下,LED照明的平均消耗功率比螢光燈更少40%,也比白熾燈的的平均消耗功率低80%。隨著全球安裝更多的LED,他預期LED對於減少全球碳足跡的影響力將會更加顯著。

根據IHS對於LED元件供應商的市佔率資料分析,日本LED供應商日亞化學(Nichia Corp.)對於減少碳足跡的貢獻最多,節省了大部份的碳。該公司由於在2017年使用LED而減少了大約10%的CO2排放,約5,700萬噸。

Cree則以8%的CO2排放量成績緊追在後。其他像是Lumileds、首爾半導體(Seoul Semiconductor)、木林森(MLS)、三星(Samsung)和LG Innotek的減碳量約佔 4%至7%。
