The number and power of LED panel lights required for living rooms and conference rooms depend on space size, functional needs, and usage preferences. Below is a detailed, optimized guide to help you determine the right configuration for each space, including key calculations, standards, and practical recommendations:
1. LED Panel Light Requirements for Living Rooms
Living rooms prioritize ambient comfort (for relaxation, socializing, or casual activities) and even light distribution. Here’s how to calculate and choose:
Key Standards & Calculations
- Recommended Illuminance: The baseline standard is 100 lux (lx) for basic daily use. For enhanced comfort (e.g., reading, playing with kids), 150–200 lx is preferred.
- Space Utilization Factor: Typically 0.8 for standard living rooms (accounts for light loss from walls, furniture, and ceiling materials).
- Luminous Efficacy of LED Panels: Quality LED panel lights have a luminous efficacy of 70–80 lumens per watt (lm/W).
Example Calculation (for Reference)
For a 50㎡ living room with a 3m ceiling height:
- Required luminous flux = (Recommended illuminance ÷ Utilization factor) × Room area
- At 100 lx: (100 ÷ 0.8) × 50 = 6,250 lm
- At 200 lx: (200 ÷ 0.8) × 50 = 12,500 lm
- Required total power = Total luminous flux ÷ Luminous efficacy
- For 6,250 lm: 6,250 ÷ (70–80) ≈ 80–90W
- For 12,500 lm: 12,500 ÷ (70–80) ≈ 155–180W
Practical Configuration Tips
-
For Small-to-Medium Living Rooms (20–30㎡):
Aim for 80–120W total power. Options include:- 1 large LED panel light (e.g., 600×600mm, 80–100W) as the main light, plus 4–6 5W downlights to fill corners.
- 2 medium panels (e.g., 300×600mm, 40–60W each) for irregular layouts (e.g., long, narrow rooms) to ensure even lighting.
-
For Large Living Rooms (40–60㎡):
Aim for 120–200W total power. Suggestions:- 2 large panels (e.g., 600×1200mm, 80–100W each) installed symmetrically.
- 1 large panel (100–120W) + 8–10 downlights (5W each) + LED strip lights (for ambient glow behind TV or crown molding) for layered lighting.
-
Color Temperature: Choose 4000K (neutral white) — it balances warmth (avoiding a dim, yellowish feel) and clarity (avoiding harsh, cool blue light), ideal for daily relaxation and activities.
2. LED Panel Light (or Display) Requirements for Conference Rooms
Conference rooms focus on functional brightness (for presentations, note-taking, and video conferences) and visibility. Unlike living rooms, they may also use LED displays for presentations — here’s how to plan both lighting and displays:
A. LED Panel Lights for Conference Room Illumination
- Recommended Illuminance: Higher than living rooms, at 200–300 lx (to ensure clear visibility of documents, whiteboards, and screens without eye strain).
- Space Utilization Factor: 0.7–0.8 (conference rooms often have more furniture, e.g., long tables, cabinets, which block light).
Example Calculation (for a 30㎡ Conference Room, 3.5m Ceiling)
- Required luminous flux = (250 lx ÷ 0.8) × 30 ≈ 9,375 lm
- Required total power = 9,375 ÷ (70–80) ≈ 115–135W
Practical Configuration
- Install 3–4 LED panels (e.g., 600×600mm, 30–40W each) in a grid pattern above the conference table — avoid placing lights directly above the presentation screen (to reduce glare on the screen).
- Add 2–4 dimmable downlights (10W each) near whiteboards or projection areas for targeted lighting.
- Color Temperature: 4500–5000K (cool white) — enhances focus and readability, suitable for formal meetings and presentations.
B. LED Displays for Conference Room Presentations
If your conference room requires a display (instead of or in addition to a projector), consider these factors:
| Factor | Recommendations |
|---|---|
| Aspect Ratio | 16:9 or 16:10 (matches most computer resolutions, video formats, and presentation slides). |
| Pixel Pitch | Determined by the distance from the first row of seats to the screen: - ≤3m distance: Choose P1.875 or smaller (for clear details when viewing up close). - 3–5m distance: P2.0–P2.5 (balances clarity and cost). - >5m distance: P3.0 or larger (sufficient for long-distance viewing). |
| Brightness | 500–800 nits (cd/㎡) — bright enough to counter ambient light (e.g., from windows or panel lights) without causing glare. |
| Cost Reference (as of 2024) | - P1.5 pixel pitch: ~¥10,000 per ㎡ - P2.0 pixel pitch: ~¥5,000 per ㎡ - Note: Costs vary by brand, refresh rate, and installation complexity. |
Final Notes
- Avoid Overlapping Glare: For conference rooms, ensure panel lights are not aligned with the display screen — use anti-glare panels or adjust the light angle if needed.
- Dimmable Options: Both living rooms and conference rooms benefit from dimmable LED panels — adjust brightness for different scenarios (e.g., movie nights in living rooms, video conferences in conference rooms).
- Professional Customization: For large or irregularly shaped spaces (e.g., 50㎡+ conference rooms), consult an interior lighting designer to optimize layout, brightness, and energy efficiency.
