इंग्रजी मध्ये LUMINOUS EFFICACY म्हणजे काय?
चमकदार कार्यक्षमता
प्रकाशयुक्त परिणामकारकता एक प्रकाश स्रोत आहे जो प्रकाशझोत दृश्यमान प्रकाश तयार करतो. हे सशक्त प्रकाशाचे प्रमाण आहे. संदर्भाच्या आधारावर, ऊर्जा एकतर स्त्रोताच्या आउटपुटचे उज्ज्वल प्रवाह असू शकते किंवा स्रोत द्वारे वापरण्यात येणारी एकूण ऊर्जा असू शकते. या शब्दाचा कोणत्या अर्थाचा हेतू आहे हे सहसा संदर्भातून अनुमान काढले जाऊ शकते, आणि काहीवेळा अस्पष्ट आहे. जुन्या अर्थाने कधीकधी किरणोत्सर्वाचे चमकदार परिणामकारण म्हटले जाते, आणि स्त्रोताच्या नंतरच्या प्रकाशाची कार्यक्षमता. स्त्रोताची चमकदार कार्यक्षमता ही कार्यक्षमतेचा एक मोजमाप आहे ज्यात स्त्रोत वीजपासून दृश्यमान प्रकाश पुरवतो. रेडिएशनची चमकदार कार्यक्षमता, स्त्रोतांमधून दिलेली इलेक्ट्रोमॅग्नेटिक रेडिएशन किती प्रमाणात दृश्यमान प्रकाश उत्पन्न करते त्याचे वर्णन करते: चमकदार प्रवाह पासून उज्ज्वल प्रवाह करण्यासाठीचे गुणोत्तर मानवी डोळ्यांच्या वर्णक्रमानुसार संवेदनशीलतेमुळे मानवी दृश्याला उत्तेजन देणारे सर्व तरंगलांबी तितकेच दृश्यमान किंवा तितकेच प्रभावी आहेत; स्पेक्ट्रमचे अवरक्त आणि अतीनीय भागांमधले रेडिएशन प्रदीपनसाठी निरुपयोगी आहे.
इंग्रजी शब्दकोशातील luminous efficacy व्याख्या
शब्दकोशात चमकदार कार्यक्षमतेची परिभाषा म्हणजे किरणोत्सर्ग आणि त्याच्या सुसंगत प्रकाशाचा प्रवाह कश्मीरच्या प्रकाशाचा प्रवाह होय. प्रकाशाच्या प्रभावाची इतर परिभाषा विकिरण स्त्रोताच्या उत्सर्जित प्रकाशाचा भाग आहे आणि ती वापरलेली शक्ती. तो वॅट ηv, Φv प्रति lumens मध्ये मोजली जाते.
