Liczba wymagań: 59
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 v1 — pytania do Marcina

Arkusz stoi na założeniach poniżej (v0: pierwsze przebiegi, v1: poprawki po recenzji, te same liczby). Twoje odpowiedzi trafią do wersji v2 (v0 i v1 zostają bez zmian).

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)?

Rozpoznanie konkurencji i źródła

Lampa v1 — research i konkurencja

Wersja v1 = v0 z poprawkami arkusza (lista w CHANGES.md); treść badań bez zmian.

Streszczenie (dla Marcina i Pawła)

Rynek ma trzy piętra. Tanie lampy z lupą za 100–350 zł mają zimne 6500 K, małe soczewki i słabe ramiona. Średnie za 1000–2150 zł (Luxo LFM/Wave, Daylight Omega) dają CRI 80 przy stałych 4000 K albo 3 presety barwy. Premium za 2650–4700 zł (Luxo Wave ESD, Waldmann TEVISIO) mają Ra ≥ 90, R9 ≥ 50, szkło z powłoką AR i 4 przełączane sektory — ale nadal stałą barwę i żadnego światła z niskiego kąta.
Luka potwierdzona: nikt nie łączy dużej szklanej lupy, płynnej bieli 1800–6000 K z natywnych diod z CRI 95, oświetlenia kontrastowego (sektory, niski kąt, warstwy RGB), polaryzacji, kamery i dobrego ramienia. Najbliżej są Aven Mighty Vue (lupa + kamera + 3500–6500 K, ok. 425–645 USD) i TEVISIO (sektory, ok. 4300 zł).
Diody: natywne białe 1800 K istnieją (Nichia R9050, Yuji 1800 K; CRI 90–95, ok. 25 % mniej wydajne). Mieszanie tylko dwóch kanałów 1800 K i 6000 K daje odchyłkę od krzywej Plancka Duv ≈ −0,014 (widoczny zielono-różowy nalot) — potrzebne co najmniej trzy kanały białe albo kanał korekcyjny (OBLICZENIE). Migotanie: PWM ≥ 3 kHz (strefa „bez efektu” IEEE 1789) albo prąd stały; w UE SVM ≤ 0,4.
Oświetlenie kontrastowe to główne wyzwanie konstrukcyjne. Pierścień wokół lupy na wysokości ok. 25 cm świeci pod kątem 60–70° — to nie jest „niski kąt”. Światło ślizgowe 10–30° (krawędzie, rysy) wymaga źródeł blisko blatu, np. niskiego pierścienia albo listew, które nie przeszkadzają rękom. Warstwy RGB jak w AOI: czerwony z góry, zielony ze środka, niebieski nisko — kolor pokazuje nachylenie lutu. Polaryzacja zabiera 7–10× światła; UV 365 nm pokazuje lakier i topnik.
Na co narzekają użytkownicy: opadające ramię (najczęściej), za mała odległość robocza przy 5–8 D (lutownica i pędzel uderzają w lupę), małe soczewki ze zniekształceniami i barwnymi obwódkami, zimne i ostre światło, odblaski z lutów, migotanie na kamerze, brak presetów, przyciski na głowicy, które ją przesuwają. Wielu w końcu używa samej lampy bez lupy.
Normy: EN 60598-1 + EN 60598-2-4 (oprawy przenośne), EN 62471 / IEC TR 62778 (światło niebieskie z 200 mm), EMC EN IEC 55015 + EN 61547, ekoprojekt (UE) 2019/2020 (wymienne źródła światła, migotanie), etykieta 2019/2015 (EPREL), zasilacz 2019/1782. Lampa zasilana z USB-C (bez sieci w środku) jest poza dyrektywą niskonapięciową i podlega GPSR. USA: FCC Part 15B, UL 153 + UL 8750.
Cena w v0: 349 € (ok. 1500 zł) w detalu, koszt produkcji ≤ 95 € przy 1000 szt. (poniżej progu 2–3 tys. zł, o którym pisał Marcin).

Wszystkie liczby z etykietą pochodzenia; ceny widziane 30.10.2026. Szczegóły poniżej (po angielsku).

1. Scope and method

Six parallel web-research agents (2026-10-30, 03:22–03:32 Warsaw), one slice each: magnifier lamp market (L1), contrast/inspection lighting (L2), LEDs and photometry (L3), standards (L4), customer voice and alternatives (L5), mechanics and magnifier optics (L6). Every number in the raw data carries its URL; manufacturer claims are marked. Raw data (not in git): /srv/dd-data/w3/research/L*.json, checksums in /srv/dd-data/w3/research/SHA256SUMS. Known limits: Reddit and some shop pages were blocked (403/429) — customer complaints are a tally of distinct sources; the Vision Datum page returned 429 to one agent but was read by another (L2).

Observations (SOURCE unless marked):

Adjustable CCT exists only as 2-3 presets (Daylight 2700/4000/6000 K) or a narrow white + amber mix (Aven 3500-6500 K). Continuous native-white tuning down to 1800 K: none found.
Contrast/directional light: only TEVISIO (4 segments, 3 scenes), Eschenbach varioLED flex (ring/segment) and Luxo Wave (left/right modules). No low-angle (raking) light on any lamp.
Camera: only Aven Mighty Vue Inspector (1080p30, HDMI + USB-C, 419-645 USD) and Mantis PIXO (from 6,855 USD).
Lux claims use incompatible distances (15 cm, 30 cm, „focal length”, none) and conflict for the same model (Luxo KFM 3000 vs 5700 lx at 13 in) — so v0 fixes the measurement plane (the focal plane).
Flicker metrics: none of the lamps publishes any.
Crowdfunding: no magnifier/inspection lamp campaign found; high-CRI desk lamps do well (Redgrass R9 SOLO CHF 378,731 from 2,560 backers, Jan-Feb 2025; CRI 98.5 claim).

3. LEDs and photometry

Native white parts (SOURCE: L3): Nichia Optisolis NF2W/NF2L757G-F1 (3030; Ra ≥ 95, R9 ≥ 80-85, 2700-6500 K, 122-134 lm/W, ~0.99 EUR each at small quantities); Nichia NFSW757H-V1 R9050 at 1800 K (CRI 90 class, 15-25 lm); Yuji BC 2835 1800-20,000 K (Ra 95+ typ., min 93 at 1800 K, TLCI 97 claim, ~90 lm/W); Seoul SunLike 3030 (CRI ≥ 95, R9 > 85, no 1800 K part found); Samsung LM301H CRI 90; Lumileds LUXEON 3030 2D (CRI 90 bins, R9 ≥ 50 at 6500 K). The 1800 K channel is ~25 % less efficient than 2700 K (Yuji strip data, CALCULATION).
Duv when mixing (CALCULATION, L3, CIE 1960 uv with endpoints on the locus): 2 channels 2700/6500 K worst Duv = -0.0063 at ~3900 K; 1800/6000 K -0.0144 at ~3000 K; 1800/6500 K -0.0158. A third (mid-CCT or mint) channel brings it within ±0.003. Duv > ~0.002 is visible; ANSI C78.377 tolerance is commonly ±0.006.
Colour rendering: premium lamps are Ra 80-90; only Waldmann publishes R9 (≥ 50). TLCI (EBU Tech 3355) bands 85-100 / 75-85 matter for camera documentation.
Flicker (SOURCE): IEEE 1789-2015 low-risk: modulation % ≤ 0.08 × f (90-1,250 Hz), no limit above 1,250 Hz; no-observable-effect: % ≤ 0.0333 × f → 100 % PWM needs ≥ ~3 kHz. EU 2019/2020 (amended by 2021/341): Pst LM ≤ 1.0, SVM ≤ 0.4 from 1 Sept 2024 (applies to mains light sources; the containing-product rule can make the whole lamp the light source). Camera banding: PWM > 1 kHz avoids phone banding; 20 kHz used for film/TV.
Illuminance (SOURCE): EN 12464-1 — precious stones 1,500/2,000 lx (Ra 90, Uo 0.70), jewellery 1,000/1,500 lx, watchmaking 1,500/2,000 lx, very fine electronic assembly 1,000 lx (Ra 80); values may be raised one step for small, low-contrast details. Watchmaking practice 1,500-3,300 lx. Flux budget (CALCULATION, L3): 2,000 lx on a Ø300 mm field needs 141 lm on the task (~280 lm source at 50 % utilisation); 5,000 lx needs ~710 lm.
Glare (SOURCE + CALCULATION): EN 12464-1 shielding angles 15°/20°/30° for 20-50 / 50-500 / ≥ 500 kcd/m²; a bare 3030 LED is ~1,200 kcd/m², so emitters must be hidden or diffused ~60× to get below 20 kcd/m².
Photobiological (SOURCE): EN 60598-1 4.24.2 with IEC TR 62778 — blue-light assessment at 200 mm; portable luminaires above RG1 at 200 mm need marking; most white power LEDs are RG2 at 200 mm unless diffused; the 6000 K channel and any blue tier are the critical cases.
Lumen maintenance (SOURCE/CALCULATION): LM-80/TM-21 example (Samsung LM281B) L90 ≈ 23,000 h at Ts 85 °C; +10 °C junction typically costs 30-50 % of life (vendor heuristic).

Bright field vs dark field (SOURCE, Edmund/Advanced Illumination): bright field 45-90° elevation; dark field 0-45°, in machine vision down to 10-15°. Low-angle light makes flat surfaces dark and edges, scratches, engravings and solder profiles bright; it needs short distances (Edmund: ~50 mm; SVL RM140-4Z WD 50-200 mm).
Colour-coded tiers (SOURCE, Omron): three elevation levels — red from the upper, green from the middle, blue from the lower; gently tilted solder shows red, steep shows blue. Typical wavelengths: R 620-630, G 520-530, B 465-475 nm. Omron VT-M12 uses 39 channels (13 directions × RGB).
Segmented/quadrant rings (SOURCE): microscope 4-zone rings 64-144 LEDs, ~4 W, 81-264 USD (AmScope), 470-1,350 PLN in Poland; machine-vision segmented rings 410-480 EUR net (MBJ); Vision Datum KR multi-layer RGB ring from 609 USD (Ø73 mm), sizes up to Ø250 mm.
Geometry (CALCULATION, L2): elevation θ = atan(h/r). A ring Ø190 mm around a Ø160 lens at h = 150 / 250 / 400 mm gives 57.7° / 69.2° / 76.6° — bright field only. 30° from the head at h = 150 mm would need a Ø520 mm ring. A low ring Ø200 mm with emitters 30 mm above the work gives 16.7° at the field centre (31° at the near edge, 11° at the far edge of a Ø100 mm field). Horizontal illuminance drops with sin(θ): 3.5× less at 16.7° than overhead.
Cross-polarisation (SOURCE + CALCULATION): polariser films 100:1 to 11,000:1 at ~38 % transmission; light through polariser and analyser ≈ 14 % of the unpolarised case (≈ 7× dimmer; VA Imaging measured ~10×).
UV (SOURCE): IPC-CC-830 conformal coatings fluoresce under ~365 nm; 365 nm gives better contrast than 395 nm; IEC 62471 UV-A eye limit 10 W/m² for t > 1,000 s; risk groups Exempt < 10, RG1 < 33, RG2 < 100 W/m² (IEC 62471-6:2022 for UV lamps).
What „contours visible” can mean as a test (proposal, L2): reference samples (scratched polished aluminium, embossed part, PCB solder fillets), camera through the lens at fixed exposure, Michelson contrast of the features ≥ 0.3 and ≥ 3× the uniform bright-field contrast — v0 uses the factor (LAM-PRF-13) as an ASSUMPTION to calibrate.

5. Customer voice

SOURCE: L5 slice (EEVblog, elektroda.pl, hobby forums, reviews). Main themes:

arms that droop, drift or wobble; clamps that slip; buttons on the head that push it down;
wrong working distance — 5-8 D lenses put the focal point closer than a brush or soldering iron („don't go over 3 dioptres”; Polish users swapped 8 D lamps for 5 D);
small lenses, distortion, red/blue fringes, reflections; inflated „10X” claims (8 D ≈ 3x);
cold, harsh, point-like light; poor colour; glare on shiny solder (3,500-4,500 K preferred by some);
flicker and banding on camera at low dimming;
shadows from hands and tools; multiple shadows;
heat in cheap heads (overheating driver transistors);
controls in the base, no presets, no hands-free control;
many owners end up using the lamp without the lens (OptiVisor 55-70 USD is the most recommended alternative); stereo microscopes „nothing beats” for SMD. Buyers: electronics engineers and repair techs, watchmakers, jewellers, miniature painters, model makers, QA. Price expectations: hobby 50-80 USD for a durable lamp, premium 150-300 USD; Polish market as in §2.

6. Optics, mechanics and standards

6.1 Optics (SOURCE: L1, L6 unless marked)

Magnification conventions: M = 1 + D/4 (trade; 3 D = 1.75x, 3.5 D = 1.88x, 5 D = 2.25x, 8 D = 3.0x) vs M = D/4 (250 mm near point). Viewed from 300-400 mm the real angular magnification is closer to D/4 — so the design must name the convention.
f = 1000/D mm: 3 D 333 mm, 3.5 D 286 mm, 5 D 200 mm, 8 D 125 mm; Luxo working distances 292-318 mm (3 D) and 165-190 mm (5 D).
Two-eye field (CALCULATION, L6): common field = (D_lens − 63 mm) × f / l; a 127 mm 5 D lens at l = 350 mm gives only ~37 mm — large low-power lenses are needed for binocular viewing.
Lens mass (CALCULATION, L6, crown glass 2.51 g/cm³, 2.5 mm edge): 127 mm 3 D 268 g; 150 mm 3 D 479 g; 150 mm 5 D 743 g; 178 mm 3 D 890 g; 178 mm 5 D 1,435 g.
AR: uncoated glass ~4 % per surface (~15 % at 60°); single-layer MgF2 ≤ ~1.3 %; multilayer ≤ 0.5 %.
Materials: N-BK7 n 1.517, Abbe 64; PMMA n 1.49, Abbe 57-58 (scratches, hazes); polycarbonate Abbe ~30 (fringes).

6.2 Mechanics (SOURCE: L6 unless marked)

Balance: exact spring balance at every angle needs a zero-free-length spring, k = m·g·r / (b·c); example (CALCULATION) 1.2 kg at r = 0.5 m, b = 0.04 m, c = 0.08 m → k = 1.84 N/mm, max tension 221 N.
Friction joints: torque tolerance ±30 %, ~80 % retention at end of life → nominal torque ≈ 1.8 × holding need.
Gas springs: narrow load window (±10 %), temperature-dependent; mechanical springs tolerate ±25 %.
Reach on the market: TEVISIO 784 mm, Luxo 762-1,143 mm, Daylight 1,080-1,180 mm, Anglepoise 1227 900 mm.
Clamp/mount (CALCULATION): overturning moment at 1 m reach 11.8-23.5 N·m (head 0.8-1.8 kg); a free-standing base would need 10-20 kg (Luxo sells an 18.6 kg base) → clamp or pin socket is the primary mount.
Cables (SOURCE): EN 60598-1 4.14.3 — joints must not twist cables more than 360°; flexing test 1,500 cycles for frequently adjusted luminaires; cord anchorage 25 pulls at 60 N + 0.15-0.25 N·m torque.

6.3 Standards and regulations (SOURCE: L4)

Safety: EN IEC 60598-1:2021+A11:2022 with EN 60598-2-4:2018 (portable general-purpose luminaires; stability on a 6° incline indoors). Table 12.1: means of adjustment 60 °C (metal) / 75 °C (non-metal).
A 5-20 V USB-C lamp sold without a mains adapter is outside the LVD (50-1,000 V AC); its safety falls under GPSR 2023/988 with EN 60598 as the state of the art; a bundled mains adapter brings LVD (EN 62368-1) and EPS Ecodesign (EU) 2019/1782 (no-load ≤ 0.10-0.30 W; 45 W multi-voltage ≥ 84.7 % average efficiency).
Photobiological: EN 62471 + IEC TR 62778 (assessment at 200 mm; mark if above RG1).
EMC: EN IEC 55015:2019+A11:2020 (emissions), EN 61547 (immunity: ESD ±4 kV contact / ±8 kV air), EN 61000-3-2 Class C / -3-3 for mains-connected parts; EN 55032/55035 for a camera.
Ecodesign (EU) 2019/2020: light sources and control gear replaceable with common tools (or a technical justification); standby and networked standby ≤ 0.5 W; CRI ≥ 80; Ponmax ≈ 11.7-12.3 W for a directional 800 lm CRI 95 source (CALCULATION). Energy labelling (EU) 2019/2015: high-CRI tunable lamps tend to land in class F/G; EPREL registration and a manual statement.
Radio (only if BLE/Wi-Fi): RED 2014/53/EU with EN 300 328, EN 301 489-1/-17, EN 62479 (≤ 20 mW exclusion); internet-connected → RED cybersecurity 2022/30 with EN 18031 (from 1 Aug 2025); Cyber Resilience Act 2024/2847 (reporting since 11 Sep 2026, full duties from 11 Dec 2027).
RoHS (EU) 2015/863, WEEE 2012/19/EU (Poland: BDO register), GPSR labelling and EU responsible person.
US: FCC Part 15 Subpart B (SDoC; LED drivers are unintentional radiators), §15.247 + §15.212 modular FCC ID for a radio; UL 153 Ed. 13 (2025, covers USB-powered portable luminaires; 8° stability; 90 °C external surface, „CAUTION: Hot surface” up to 150 °C), UL 8750 for LED parts, adapter UL 62368-1 / UL 1310 Class 2 and DOE Level VI.
Voluntary: IEC 61340-5-1:2024 (ESD; work surfaces Rg < 1e9 Ω), ISO 15253 (magnifier metrics: magnification, working distance, distortion).

7. Price, cost and unit economics

v0 price target 349 EUR incl. VAT (≈ 1,500 PLN; ASSUMPTION: under the 2-3 thousand PLN where Marcin found nothing with options, at the branded-mid price level), threshold 499 EUR (≈ 2,150 PLN).
Unit economics (CALCULATION, illustrative): 349 EUR incl. 23 % VAT → 284 EUR net; distributor sale at ~35 % margin → ~185 EUR to the brand; at 95 EUR unit cost the gross margin is ~49 %, at 140 EUR ~24 %.
Rough cost structure at 1,000 units (ASSUMPTION, to be replaced by the designs' BOMs): AR-coated 160 mm glass lens 8-20, white LEDs (3 channels, ~100-150 LEDs) 15-45, RGB/UV/low-angle LEDs 8-20, multi-channel driver + MCU + USB-PD board 10-18, arm/joints/springs/clamp 15-30, head housing and diffusers 6-12, 45 W USB-C adapter 6-10, packaging 4, assembly + calibration + test 5-10 EUR → 77-169 EUR. Hence the 95 EUR target and 140 EUR threshold.

8. Gaps and uncertainties

The contour-visibility factor (LAM-PRF-13) and the drift limits are proposals, not measured values.
Native 1800 K high-CRI parts are few (Nichia R9050 is an older model; Yuji is a smaller vendor); availability at 1,000-unit volumes was not checked.
Whether Ecodesign 2019/2020 treats a USB-C (non-mains) lamp's flicker limits as binding depends on the containing-product classification; v0 sets the limits as requirements anyway.
Exchange rates (1 EUR ≈ 4.3 PLN) and several retailer prices are snapshots; Polish prices are mostly gross, distributor prices net (marked in the tables).
