灯光层次
Overview
Lighting design in layers — ambient, task, and accent — creates flexible, comfortable spaces. This skill covers layering strategy, fixture placement, and daylight coordination.
When to Use
- Designing a complete lighting scheme for a room or building
- Selecting fixtures for specific tasks (reading, cooking, display)
- Balancing natural and artificial light
- Specifying dimming controls and scenes
Key Principles
- Three layers — ambient (general fill), task (focused work light), accent (highlight features).
- Daylight first — design around natural light; supplement where it falls short.
- Color temperature — 2700-3000K residential, 3500-4000K commercial, 5000K+ industrial.
- Glare control — shield bright sources from direct eye view; use indirect or diffused fixtures.
- Dimming — every layer should dim independently for scene flexibility.
Process
- Assess daylight availability (window orientation, shading).
- Plan ambient layer — ceiling fixtures, cove lighting, or indirect pendants.
- Add task layer — under-cabinet, desk lamp, reading sconce.
- Place accent layer — track spots, wall washers, in-ground uplights.
- Specify controls — dimmers, scenes, occupancy sensors.
- Review light levels against IESNA recommendations.
Common Pitfalls
- Relying on a single central fixture — flat, shadowless light.
- Ignoring vertical surfaces — wall washing adds perceived brightness.
- Wrong color temperature mixing — inconsistent CCT feels unsettling.
- No dimming — spaces need different light levels for different activities.
Verification Checklist
- [ ] All three layers present in each room
- [ ] Daylight integrated before artificial light
- [ ] Color temperature consistent within zones
- [ ] Glare sources shielded
- [ ] Dimming controls specified for each layer
