HL-A004 — Marunouchi Gallery Hall, Tokyo Ceiling-Corner Cove Lighting

Project City

Tokyo, Japan

Project Description

Marunouchi Gallery Hall, a 2-storey art space in Tokyo’s Marunouchi business district, installed ceiling-corner cove lighting along every gallery wall and the central circulation spine. The HELIAN HL-A004 ceiling-corner profile was selected for its strict PC-only diffuser family, which satisfied the gallery’s fire / smoke classification in a single material declaration.

User Pain Points and Needs

  • Need 1 — Single-material fire-safety documentation. The gallery authority required all plastic diffusers to be the same chemistry, with a single fire-test report.
  • Need 2 — Dual-direction corner illumination. Both the wall and the ceiling in the corner required independent LED channels.
  • Need 3 — Visual continuity. Gallery walls up to 24 m required single-direction light lines with no visible joints.

Решение

HELIAN supplied the HL-A004 profile from its A-Series:

  • Body: AL 6063 aluminium with anodised or painted silver surface.
  • Lighting source width: max 13 mm / max 7 mm.
  • Cover (PC only): PC; Cover Model BAPL02S.
  • Accessories: End Cap, Clip, Suspended Rope (Set), Connector.
  • Длина: 4 m / max.
  • Application: Потолочное угловое освещение.

Implementation Results

  • Single-material fire approval. The PC-only diffuser family cleared the gallery authority’s fire review in a single material submission.
  • Asymmetric corner wash. 13 mm / 7 mm channels delivered the gallery’s desired wall-emphasis lighting scheme.
  • Long gallery runs. Wall runs up to 24 m were formed by clean 4 m stock joints with no visible mid-span joints.
  • Quantified outcome. 410 m of HL-A004 installed across 2 floors; the fire-clearance review completed in one cycle with zero additional submissions.
