## What is Lighting Calculations?

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.

### 2/5 — «Ежегодная подписка»? - В «мусорное ведро»!

*2021-02-02*

Обычно каждый из нас платит за какую-то «уникальность». Что такого «уникального» в этом «сборнике», чего я не нашёл бы в «открытых источниках» в Интернете, и за что я согласился бы на квартальную/ежегодную подписку? - Ничего. Приложение - в помойку.

### 5/5 — The Best

*2019-08-18*

I love this app
It has plenty of information

### 5/5 — Fantastic app!!

*2019-01-30*

Great app, I am very grateful to the developers for providing these tools.

### 5/5 — Avis

*2017-12-01*

Super coool

### 3/5 — Free version just allows you to see what the pro version doed

*2017-01-18*

If you're already a professional lighting designer you can probabably work out whether this does what you want from the free version. If you're an amateur (I'm a qualified electrical engineer, but not a lighting specialist) it won't - you can type in the data it wants and get bombarded with ads, but you can't calculate anything.

But the pro version is well worth having and is being actively developed - a good thing in an app.
