ARCHITECTURAL DIGITAL MONOGRAPH // CV25

CONVEX C-25

Sub-miniature plaster-in concealed cove and millwork profile

Designed for knife-edge ceiling perimeter reveals and architectural joinery. Delivers a continuous 120° batwing indirect wash across ceiling slabs with zero socket shadows or color shifting across 20-meter continuous runs.

Engineered Light Emission Hierarchy.

Inspect the mechanical and optical layering inside CONVEX C-25. Every optical interface is calibrated to minimize Fresnel reflection loss and eliminate glare.

01 // PASSIVE THERMAL HEAT SINKAEROSPACE 6063-T6

CNC-turned aluminum body dissipating thermal load without fans, ensuring L90B10 > 100,000h diode life.

02 // SOLID-STATE COB EMITTERSDCM ≤ 1.5 // 2700K

Custom phosphor-converted LED array delivering 98 CRI with high R9 saturation (96) and strict sub-1.5 MacAdam ellipse.

03 // TOTAL INTERNAL REFLECTION (TIR) QUARTZFWHM 85°

Total Internal Reflection collimator focusing 92% of emitted photons into the primary cone without stray halo light.

04 // SPECULAR DARKLIGHT BAFFLE & HONEYCOMB55° CUTOFF

Secondary anti-glare cellular louver absorbing all off-axis photons to keep aperture appearance completely dark.

05 // ARCHITECTURAL APERTUREContinuous reveal slot 30mm

Perforated mud-in plaster bead allowing drywall compound flush feathering with zero visible metal collar.

SHIELDING & GLARE SUPPRESSION

Darklight Visual Comfort

CONVEX C-25 incorporates a physical 65° shielding angle. Observers seated or walking through the space experience zero direct line-of-sight exposure to the glowing LED chip, maintaining clean sightlines and eliminating eye-adaptation fatigue.

UGR CLASSIFICATIONUGR < 3 (Indirect Concealed)

Exceeds WELL Building Standard v2 Part L04 glare requirements.

05 // PHOTOMETRIC BEAM PHYSICS

Polar Candela Distribution.

Real-world laboratory goniophotometric curve measured per ANSI/IES LM-63. Interactive angle inspection proves zero stray candlepower beyond the 65° visual shield.
