Share
What is Cove LED Lighting?
Cove LED lighting is a modern lighting technique where the light source is hidden, and only the light itself is perceived. It is created with LED strips placed in ceiling coves, niches, under cabinets, and behind walls.
Areas of Use
- Ceiling cove: Light strip running around the ceiling
- Niche lighting: LEDs placed in wall recesses
- Under cabinet: Under kitchen counters, wardrobe bottoms
- Behind TV: Ambient light behind the screen
- Stairs: LEDs under or next to steps
- Headboard: Wall strip behind the bed
- Bathroom mirror surround: LEDs around the mirror
Required Materials
| Material | Recommended | Note |
|---|---|---|
| LED strip | COB or SMD 2835 | COB ideal for homogeneous light |
| Transformer (driver) | 12V or 24V | Select according to wattage calculation |
| Aluminum profile | With diffuser | Dissipates heat, softens light |
| Diffuser cover | Matte or transparent | Matte = soft light |
| Connection cable | 2x0.75mm | Low voltage is sufficient |
| Dimmer (optional) | PWM dimmer | Atmosphere control |
How to Install Ceiling Cove Lighting?
- Measurement: Measure the perimeter of the ceiling
- Profile cutting: Cut the aluminum profile according to the measurement
- Installation: Secure the profile to the ceiling with screws
- Strip placement: Adhere the LED strip to the profile
- Connection: Connect to the transformer, use connectors at corners
- Diffuser: Attach the matte cover
- Test: Power on, check for even light distribution
Transformer Calculation
Formula: Total Wattage = Meters x W/m + 20% allowance
| Area | Meters | LED (10W/m) | Transformer |
|---|---|---|---|
| Living room cove | 16m | 160W | 200W transformer |
| Bedroom | 12m | 120W | 150W transformer |
| Kitchen counter | 3m | 30W | 40W transformer |
Color Temperature Selection
| Area | Recommended Kelvin | Effect |
|---|---|---|
| Living room cove | 2700-3000K | Warm, luxurious atmosphere |
| Headboard | 2700K | Relaxing, romantic |
| Kitchen counter | 4000K | Functional, clear |
| Behind TV | 6500K or RGB | Reduces contrast |
| Bathroom mirror | 3000-4000K | Natural color |
Common Mistakes
- ❌ Not using aluminum profile — light spots visible
- ❌ Insufficient transformer — LED flickers or turns off
- ❌ Cutting errors at corners — use connectors
- ❌ Too bright strip — 5-8W/m is sufficient
- ❌ IP rating — use IP44+ strip in bathrooms

FAQs
Is an electrician needed for cove LED lighting?
An electrician is recommended for transformer connection. You can install the strip yourself.
COB or SMD?
COB strips provide more homogeneous light for cove lighting, no visible spots.
Is an aluminum profile necessary?
Yes. It dissipates heat, softens light, and provides a professional look.
How many watts/meter should I choose?
5-8W/m for ambient cove lighting, 10-14W/m for task lighting.
