Zaprojektuj lampę biurkową dla inżynierów do elektroniki i precyzyjnej pracy ręcznej, która łączy dużą szklaną lupę, regulowaną biel o wysokim CRI z natywnych białych diod (1800–6000 K) i przełączane oświetlenie kontrastowe z wielu kątów, dzięki któremu widać kontury, rysy i kształt lutów — wszystko w jednej, dobrze sterowanej głowicy na długim, stabilnym ramieniu, w cenie wyraźnie niższej niż dzisiejsze lampy z lupą klasy premium.

Zdanie dla wariantu (po angielsku)
Design an engineering desk lamp for electronics and fine manual work that combines a large glass magnifier, tunable high-CRI white light from native white LEDs (1800-6000 K) and switchable multi-angle contrast lighting that makes contours, scratches and solder shapes visible, in one well-controlled head on a long, stable arm, at a price well below today's premium magnifier lamps.
Te wymagania widzi każdy wariant i według nich oceniamy projekty. Cel to poziom mocnego projektu, próg to minimum — poniżej progu wymaganie nie jest spełnione.

Pytania do Pawła i Marcina
Lampa v0 — pytania do Marcina
Arkusz v0 jest gotowy i stoi na założeniach poniżej, więc runda otwarcia może ruszyć bez czekania.
Twoje odpowiedzi trafią do wersji v1 (v0 zostaje bez zmian, bo przebiegi na nim stoją).
1. Lupa
Założenie: szklana lupa ≥ 160 mm, 3–3,5 dioptrii (ok. 1,75–1,9×), ok. 25 cm wolnego miejsca pod głowicą
na narzędzia, plus wymienna albo odchylana druga soczewka 8 dioptrii (3×) do drobnej roboty.
Pasuje? Chcesz większe powiększenie, inny kształt (prostokątna) albo kamerę zamiast drugiej soczewki?
2. Oświetlenie kontrastowe — co najważniejsze?
Założenie: obowiązkowo (a) sektory wokół lupy (światło z wybranej strony, ≥ 8 sektorów) i (b) światło
z niskiego kąta (≤ 20°, krawędzie i rysy). Jako cele dodatkowe: (c) warstwy RGB jak w pierścieniu
Vision Datum (kolor = nachylenie lutu), (d) polaryzacja (bez odblasków z lutów), (e) UV 365 nm
(lakier, topnik). Którą kolejność ważności przyjmujesz? Coś pominęliśmy?
3. Ramię i mocowanie
Założenie: zasięg ≥ 1 m, ramię trzyma pozycję bez opadania (≤ 3 mm na godzinę), zacisk do blatu
8–80 mm + gniazdo na trzpień 13 mm; bez ciężkiej podstawy. OK?
4. Cena i zasilanie
Założenie: ok. 349 € (ok. 1500 zł) brutto, koszt produkcji ≤ 95 € przy 1000 szt., zasilanie USB-C PD
(zasilacz 45 W w zestawie), wersja bezpieczna dla ESD w standardzie. Zapłaciłbyś więcej za coś lepszego,
czy cena ma być niższa?
5. Sterowanie i dokumentowanie
Założenie: pokrętło na głowicy (nie przesuwa lampy), ≥ 6 presetów, gniazdo przełącznika nożnego,
sterowanie z komputera przez USB; aplikacja niepotrzebna; kamera jako opcjonalny moduł (1080p).
Czego brakuje (np. pilot, aplikacja, wbudowana kamera z ekranem)?
