Key Takeaways
- Diffusers scatter light to create a soft, widely distributed illumination with minimal shadows.
- They suit various environments like homes, hotels, offices, and educational settings for comfortable lighting.
- Lenses focus light into a directed beam, ideal for retail and large spaces needing targeted illumination.
- Using lenses effectively highlights products and minimises energy waste by preventing light spread.
- The REVO luminaire showcases the advantages of both a diffuser and a lens in lighting applications.
Diffusers and lenses play different roles, in order to fulfil different requirements. Here, you can read the fundamental difference between diffusers and lenses – and the range of environments in which they are applicable.
Diffusers
A diffuser typically sits over the light source and the space being lit. As the light hits the diffusers, the light beams are scattered, resulting in a soft, widely distributed light.
The purpose of a diffuser is to create a lit environment with minimal shadows.
Commonly seen in the home and hotel in decorative fixtures, diffusers are also applicable for commercial applications, offices and educational environments, using the soft light to create comfortable working spaces.
Lenses
A lens is designed to control and focus the light from the light source (such as LED chips) to direct it into a focused beam pattern. Lenses are beneficial in retail environments, making use of shadows and brighter areas, to draw customer focus towards certain products and items.
They are also used where light is required to travel a distance before it lights anything; shopping malls, airport terminals, sports stadia, warehouses and factories all have the same requirement for directed light. A diffused light would waste energy because the light would be spread too broadly around the space.
The REVO is a high output luminaire that highlights the benefits of both lenses and diffusers.
Frequently Asked Questions
A diffuser typically sits over the light source and works by scattering light beams to create a soft, widely distributed light with minimal shadows. In contrast, a lens is designed to control and focus the light (such as from LED chips) to direct it into a specific, focused beam pattern.
Diffusers: These are used in homes, hotels, offices, and educational environments to create comfortable working spaces through soft illumination.
Lenses: These are ideal for retail environments to draw customer focus toward products. They are also used in large-scale spaces like shopping malls, airport terminals, sports stadia, warehouses, and factories where light must be directed over a distance.
In environments where light must travel a significant distance, a lens is required to direct the light effectively. Using a diffuser in these spaces would waste energy because the light would be spread too broadly around the area rather than being focused where it is needed.
