Apa yang dimaksud dengan Cahaya Alami

Cahaya alami adalah sumber pencahayaan yang secara dekat meniru penerangan yang diberikan oleh sinar matahari. Cahaya alami dicirikan oleh suhu kelvin sekitar 5.000 derajat kelvin dan indeks rendering warna (CRI) 100. The suhu kelvin Cahaya alami dapat bervariasi sepanjang hari, biasanya berkisar antara 5.000 hingga 6.000 kelvin, tergantung pada faktor-faktor seperti waktu dan tutupan awan. CRI adalah metrik yang digunakan untuk menggambarkan seberapa akurat sumber cahaya menghasilkan warna dibandingkan dengan cahaya matahari alami. Agar sumber pencahayaan diklasifikasikan sebagai cahaya alami, umumnya dianggap tepat untuk memiliki CRI di atas 90.

Beberapa perusahaan mungkin memiliki interpretasi sendiri mengenai apa yang dimaksud dengan pencahayaan alami, tetapi secara umum disepakati bahwa lampu dengan temperatur warna 6.500 kelvin dan CRI 82-84 tidak memenuhi kriteria pencahayaan alami. Demikian pula, lampu dengan suhu warna 4.100 kelvin dan CRI tinggi tidak dapat dianggap sebagai sumber pencahayaan alami, karena warna cahayanya menyimpang secara signifikan dari cahaya matahari dan hanya memiliki sedikit kemiripan dengannya.
