HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (0.2 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Store description

PROJEKTUJESZ SYSTEMY OŚWIETLENIOWE, JESTEŚ INSTALATOREM LUB PASJONATEM MAJSTERKOWANIA? "Obliczenia Oświetleniowe" to ostateczne narzędzie, które zmieni Twój smartfon w najlepszego sojusznika w projektach świetlnych. Zapomnij o złożonych obliczeniach ręcznych i ryzyku błędów projektowych. Dzięki naszej aplikacji masz pod ręką kompletny ekosystem kalkulatorów, konwerterów i tabel, zaprojektowany tak, aby oszczędzić Twój cenny czas na budowie lub w biurze. Technika świetlna nie będzie miała przed Tobą tajemnic! CO MOŻESZ ZROBIĆ Z NASZĄ APLIKACJĄ? ZAAWANSOWANE OBLICZENIA I PROJEKTOWANIE: • Projektowanie pomieszczeń: obliczanie całkowitego strumienia świetlnego, liczby potrzebnych opraw, natężenia oświetlenia i równomierności na powierzchni. • Analiza LED: żywotność diod LED (parametry L, B i C), ryzyko fotobiologiczne i obliczenia zasilaczy do taśm LED. • Efektywność: obliczanie skuteczności świetlnej, oszczędności energii lamp i kompensacja mocy biernej. • Zintegrowane narzędzia: szybkie i precyzyjne dekodowanie kodu fotometrycznego. SZYBKIE I PRECYZYYJNE KONWERSJE: • Lumeny / Luksy / Kandele / Waty (we wszystkich możliwych kombinacjach). • Luksy / Stopokandele (dla standardów międzynarodowych). • Szybkie porównanie mocy między różnymi technologiami oświetleniowymi. • Luminancja i Natężenie oświetlenia / Wartość ekspozycji (EV). • Konwersja temperatury barwowej (Kelvin) na RGB. ZASOBY, TABELE I ZAWSZE AKTUALNE NORMY: • Wymagania normatywne: poziomy natężenia oświetlenia wymagane w pomieszczeniach. • Przewodniki techniczne: typy lamp, trzonki, kształty żarówek i świetlówki. • Jakość światła: diagram Kruithofa, widmo widzialne, temperatura barwowa i wskaźnik oddawania barw (CRI). • Bezpieczeństwo i klasyfikacja: nowa etykieta energetyczna, skala olśnienia (UGR), symbole i jednostki miary. • Focus na LED: typowe cechy i specyfikacje diod LED SMD. EKSKLUZYWNY BONUS: Wewnątrz znajdziesz niezwykle przydatny PEŁNY ZBIÓR WZORÓW ze wszystkimi formułami matematycznymi techniki świetlnej, a także ogólne tabele kompensacji mocy biernej dla lamp 220V. DLA KOGO JEST TA APLIKACJA? Inżynierów, architektów, projektantów oświetlenia, elektryków, studentów i każdego, kto chce uzyskać idealne, skalibrowane i zgodne z normami oświetlenie. RZUĆ ŚWIATŁO NA SWOJE PROJEKTY! Pobierz "Obliczenia Oświetleniowe" już dziś i wznieś swoją pracę na wyższy poziom.
