Aluminium profiles normally include a diffuse or clear plastic cover, end caps and fixings as appropriate.
Using profiles can be important for 3 important functions:
1. Heat Management
By installing LED strip directly on the aluminium profile the heat generated by the LED chips can be dissipated effectively to prolong the life of the strip.
2. Light Diffusion
A diffuse cover helps to reduce glare and create a more uniform band of light.
Once installed inside profile with a clear or diffuse cover on top, the LED strip is protected from physical damage and build up of dust while the cover can easily be wiped clean.
