Designed for optimal light diffusion and a sleek finish, these aluminum profiles are ideal for under-cabinet, wall, and display applications. Compatible with various LED strip lights for versatile use.

LED aluminum channel is an important partner for professional LED strip lighting installation. Due to its low height, LED aluminum channel can be installed anywhere, and it is also suitable for places with limited spaces. Compared with the large size and prominent appearance of traditional lamps, 45 degree LED channel has the advantages of a wider range of applications. It can also be set to direct the light to a specific angel, and to provide lighting for desired areas.

Types of 45 Degree LED Channels

There are several types of 45 degree LED channel that is often to be installed at corners.

The One type comes with a semicircular light diffuser. This type offers a large angel of lighting.

The second type is designed with a square shape of light diffuser. With a 90 degree angel, the square diffuser makes itself a bolder finish, which is not seen in a semicicular diffuser.

The third type offers lighting that is more focused and directed at 45 degree from the corner. This type extends the aluminum walls of both sides inward to reduce the width of the diffuser, obtaining a smaller angle of lighting.

Using a Diffuser Cover for Enhanced Lighting

The addition of a diffuser cover is essential for achieving soft, uniform lighting without harsh spots or lines. Diffuser covers blend the light emitted by individual LED chips into a smooth beam, enhancing both functionality and aesthetics.

Advantages of Adding a Diffuser Cover:

1. Eliminates Hotspots:
Diffuser covers scatter the light evenly across the surface, eliminating visible LED chip hotspots for a professional finish.

2. Creates a Softer Glow:
The diffused light reduces harshness, making the illumination more comfortable for the eyes, especially in task-heavy areas like kitchens or offices.

3. Protects the LED Strip:
The cover acts as a shield, protecting the LED strip from dust, moisture, and accidental contact, which can prolong its lifespan.

  • Under Office Shelves: Illuminate desks or workspaces effectively without causing eye strain.
  • Display Cabinets: Showcase collectibles or products with evenly diffused accent lighting.

Installation Tips for 45-Degree LED Channels

1. Choose the Right Installation Location

  • Ensure the installation location suits the 45-degree lighting design, such as under cabinets, corners, or display cases.
  • Check that the surface is flat, clean, and free of dust or grease.

2. Reserve Cable Pathways

  • Make sure there is enough space near the installation site to arrange the cables for easy wiring.
  • Plan the power source location and cable length in advance to minimize unnecessary connections.

3. Fix the Aluminum Channel

  • Use double-sided adhesive tape or mounting brackets to secure the channel firmly.
  • If using screws, pre-drill holes to avoid damaging the channel.

4. Install the LED Strip

  • Before placing the LED strip into the channel, ensure it functions properly and clean the adhesive backing.
  • Align the LED strip carefully to avoid misplacing the LED chips away from the diffuser center.

5. Install the Diffuser Cover

  • Slide the diffuser cover into the channel from one end, ensuring even and soft light diffusion.
  • If the diffuser is difficult to fit, use a small amount of lubricant to assist.

6. Prioritize Safety

  • Avoid handling the LED strip or channel while the power is on.
  • Be cautious of the channel's edges to avoid cuts; gloves are recommended if necessary.
