How It Works

Lumina uses Konva.js, a high-performance 2D canvas library, to render the lighting design. The canvas supports:

Zoom Control: 0.3x to 5x magnification using mouse wheel. Perfect for detailed work or overview.

Pan: Hold spacebar + drag or use middle mouse button to pan across your floor plan.

Grid Snap: Toggle snap-to-grid (500mm intervals) for alignment without thinking about coordinates.

Multi-Floor Support: Design multiple floors independently. Switch between floors with tabs.

Multi-Room Support: Create unlimited rooms per floor. All rooms visible simultaneously—active in bright cyan, inactive rooms dimmed.

Fixture Placement: Click to place, drag to position. Double-click to delete. Precision positioning without frustration.

How It Works

IES Lumen Method: Industry-standard calculation using the Inverse Square Law and Cosine Law.

Room Cavity Ratio (RCR): Automatically calculated from room dimensions. Determines how light distributes in different room shapes (long narrow vs square).

Utilization Factor (UF): Lookup table based on ceiling/wall/floor reflectance. Shows how much light is actually used vs wasted.

Maintenance Factor (MF): Default 0.80 (20% light loss over time). Accounts for fixture depreciation and dust accumulation.

Real-Time Updates: Every time you move a fixture, add one, or change settings, lux values recalculate instantly.

Status Indicators: GOOD (on target), OVERLIT (too bright), UNDERLIT (too dim), DIM (critically low).

How It Works

Grid Resolution: The room is divided into a 0.5m × 0.5m grid. Each grid point calculates lux using Inverse Square Law.

Inverse Square Law: Light intensity decreases with the square of distance: E = I / d²

Cosine Correction: Accounts for angle of incidence. Light hitting at 60° is less intense than perpendicular.

6-Stop Color Gradient: Blue (150 lux) → Cyan → Green → Yellow → Orange → Red (600+ lux). Easy visual assessment.

Clipped to Boundary: Heat map respects room edges. No calculation outside walls.

Lux Legend: On-screen legend shows exact lux values for each color band.

How It Works

Toggle & Auto-Assign: Click DALI button. System instantly assigns addresses (D:1, D:2, ...) to all unprotocol'd fixtures.

Node Limit Management: Choose 64 or 128 node limit. When limit reached, system auto-creates new bus line.

Bus Cable Calculation: Calculates total bus cable length + 20% for bends. Shows in electrical panel.

Driver Schedule: Automatically generates driver requirements. Shows mA output, dimming type (DALI 2.0), and node count.

Topology Selection: Choose DAISY (series), STAR (hub), or MIXED topology. System validates wire runs.

Status Indicator: SAFE (< 80% load), WARNING (80-95% load), FULL (at capacity). Visual on canvas.

How It Works

File Support: PNG, JPG (rasterized immediately). PDF (rendered via PDF.js at 4x quality).

PDF Rendering: PDFs loaded via CDN worker for security. Rendered at 4x scale for sharp detail without huge file sizes.

Background Layer: Floor plan becomes canvas background. Grid hides automatically when plan uploaded.

Room Boundary Drawing: Click and drag directly on floor plan to draw rooms. Snaps to grid if enabled.

Dimension Popup: After drawing, popup asks for exact width/height. Unit selector (m/mm/ft/in) in one click.

Multi-Floor: Upload different plans per floor. All managed within one project.

How It Works

PDF Export: 8-page professional report including cover, lux summary, fixture schedule, electrical summary, room layouts, DALI addressing, and design notes.

Excel BOQ: 3-sheet workbook: Fixture List (quantities, wattages, costs), Electrical Components (drivers, cables, control), and Summary (costs by category).

PNG Export: High-resolution canvas snapshot (2x scale) for presentations, emails, or archival.

PDF Generation: Server-side rendering ensures consistent output. Uses PDFKit library for reliable generation.

Excel Generation: Uses ExcelJS for structured worksheets with formatting, formulas, and charts.

File Management: All exports timestamped, stored in user project folder, downloadable anytime.
