Indirect Luminaire

Definition

An Indirect Luminaire is a lighting fixture designed to distribute most of its light upwards, reflecting off the ceiling or walls to provide a soft, diffuse illumination.

Purpose

Indirect luminaires create a comfortable and glare-free lighting environment by using reflective surfaces to distribute light evenly throughout a space.

Examples of Use

• Installing indirect luminaires in office spaces to reduce eye strain and improve worker comfort.
• Using indirect lighting in residential living rooms for ambient illumination.
• Applying indirect lighting in art galleries to highlight artwork without harsh shadows.

Related Terms

• Direct Luminaire: A fixture that directs most of its light downwards or directly onto a surface.
• Ambient Lighting: General illumination that provides overall light for a room or space.
• Reflective Surface: Surfaces that reflect light, enhancing the effectiveness of indirect luminaires.

Notes

Indirect luminaires are particularly effective in spaces where glare reduction and uniform light distribution are critical, such as workspaces and public areas.
