Konsep efikasi cahaya memperhitungkan distribusi spektral cahaya yang dipancarkan oleh suatu sumber. Konsep ini mempertimbangkan kemampuan sumber cahaya untuk menghasilkan radiasi dalam kisaran panjang gelombang yang terlihat. Jika sumber cahaya memancarkan lebih banyak panjang gelombang di luar kisaran yang terlihat, fluks bercahaya (cahaya tampak) akan berkurang secara proporsional dengan fluks radiasi total. Akibatnya, kemanjuran cahaya dari sumber cahaya juga akan berkurang.<\/p>
Dalam industri pencahayaan, efikasi cahaya adalah parameter penting yang digunakan untuk menilai efisiensi dan efektivitas sumber cahaya yang berbeda. Hal ini memungkinkan para profesional pencahayaan untuk membandingkan dan mengevaluasi efisiensi energi dan performa berbagai teknologi pencahayaan, membantu dalam pemilihan sumber cahaya yang paling sesuai untuk aplikasi tertentu.<\/p>
Untuk menghitung efikasi cahaya dari suatu sumber cahaya, kita perlu membagi total fluks cahaya (dalam lumen) dengan daya listrik yang dikonsumsi (dalam watt). Contohnya, jika bola lampu 90 watt memancarkan 900 lumen cahaya tampak, maka efikasi cahaya akan dihitung sebagai berikut:<\/p>
