Pengukuran Nilai Reflektansi Cahaya (LRV)<\/h2>\n

LRV adalah ukuran persentase cahaya tampak yang dipantulkan oleh suatu permukaan, yang diukur berdasarkan sensitivitas mata manusia.<\/p>\n

LRV berkisar antara 0 hingga 100. Nilai 100 menunjukkan reflektansi absolut, sedangkan 0 menunjukkan tidak adanya reflektansi atau penyerapan cahaya total. LRV digunakan untuk menentukan dan mengontrol kontras antara berbagai material, perlengkapan, perlengkapan, dan permukaan dalam lingkungan binaan.<\/p>\n

Beberapa peraturan dan kode praktik saat ini seperti BS 8300:2009 dan BS8493:2008+A1:2010 menetapkan nilai CIE Y sebagai metode tunggal yang konsisten. Didefinisikan bahwa kontras visual akan mencukupi jika LRV permukaan yang kontras, dengan pencahayaan lebih besar dari 200 lux, berbeda minimal 20 poin. Kontras ini dihitung menggunakan rumus berikut: (B1 \u2013 B2) x 100 \/ B1, dimana B1 dan B2 masing-masing adalah LRV untuk area terang dan area gelap.<\/p>\n

LRV dapat diperoleh dengan menggunakan nilai CIE Y yang diukur di bawah pencahayaan D65 (cahaya alami) dan pengamat 10\u00b0<\/a>. Pengukuran ini dapat dilakukan dengan mudah menggunakan berbasis bola<\/a> spektrofotometer seperti Konica Minolta Spektrofotometer CM-25d<\/a> yang memilik ikalibrasi<\/a> sertifikat yang dapat ditelusuri ke standar internasional.<\/p>\n

\"\"<\/p>\n

CM-25d berbasis bola portabel d:8\u00b0 sangat ideal untuk pengukuran di lokasi, baik untuk menilai bangunan secara keseluruhan atau untuk menguji dampak paparan sinar matahari, keausan, dan pembersihan seiring waktu.<\/p>\n

Selain pengukuran LRV, CM-25d, dengan kemampuan pengulangan yang tinggi yaitu \u03c3\u2206E*ab 0,04 dan baik perjanjian antar instrumen<\/a> dari \u2206E*ab< 0,12 (rata-rata Ubin BCRA 12), juga ideal untuk pengukuran kaca arsitektur<\/a> dan lantai keramik<\/a>.<\/p>\n
