1.1 تغطي هذه المواصفات أساسًا التصميم والتصنيع واختبار المصنع ،
تسليم وضمان لنظام الإضاءة.
2- تعاريف
2.1 التدفق الضوئي ( f ):
هي الكمية الإجمالية للضوء المنبعث في ثانية واحدة من مصدر الضوء ويقاس بواسطة لومن (Lm) - العلاقة بين الطاقة الكهربائية و
التجويف هو: -
1 واط = 681 شمعة.
في 2.2 كمية الضوء (س):
إنها كمية الضوء المنبعثة ساعة واحدة نتيجة التدفق الضوئي الذي يساوي 1 لومن من مصدر الضوء ويقاس بالساعة لومن (Lm.hr).
F = f x t Lm .hr
وهو مشابه لوحدة الطاقة الكهربائية واط. ساعة (wh).
2.3 الكثافة المضيئة (I):
أنا = و م / ش.
ث
حيث: f هو التدفق المضيء و w هي الزاوية الصلبة أمام السطح والتي يتم قياسها بالستريديان (st).
2.4 الإضاءة (E):
يكون التدفق الضوئي عموديًا على مساحة وحدة السطح ويقاس بالكس (LX).
E = و لوكس
ا
حيث A = w ص 2 م²
و = ث أنا
\ E = w I = I Lm / م²
w ² r²
أي 1 لوكس = 1 Lm / م²
2.5 كفاءة مضيئة ( ح ):
هي النسبة بين خرج التدفق الضوئي إلى الطاقة الكهربائية المستهلكة في مصدر الضوء وقياسها بواسطة لومن / واط (Lm / w):
h = الإخراج المضيء Lm / w
قوة فعالة
2.6 عامل استخدام الغرفة ( h R ):
هي النسبة بين التدفق الضوئي ( f ) الموجه إلى السطح (A) ، إلى إجمالي التدفق الضوئي ( S f ) الناتج عن مصادر الإضاءة في الغرفة.
2.7 عامل الاستخدام ( h B ):
هي النسبة بين التدفق الضوئي ( f ) الموجه إلى السطح (A) ، إلى إجمالي التدفق الضوئي المعين.
