Introduction to architectural indoor lighting

The Architectural outdoor lighting uses light fixtures to enhance the look and function of building exteriors and landscapes. It highlights key features, improves safety, and makes outdoor areas usable at night. Well-designed lighting creates a welcoming atmosphere and ensures visibility.

Wall washer and landscape lighting are commonly used for:

       •      Building façades

       •      Architectural features

       •      Public spaces

       •      Outdoor landscapes

The main purpose is to highlight vertical surfaces with controlled light distribution and minimal spill light.

Lighting Objectives

Key objectives include:

       •      Uniform vertical illuminance

       •      Clean and defined beam edges

       •      Controlled cut-off to avoid light pollution

       •      Visual emphasis of architectural elements

Secondary optics are critical to achieve precise beam control in these applications.

Beam Types 

Wall washer optics typically use:

       •      Asymmetric beam patterns for uniform vertical lighting

       •      Elliptical distributions for wide coverage

       •      Sharp cut-off designs to control spill light

Symmetric optics are generally not recommended for wall washing due to inefficient light utilization.

Optical Design Considerations

Important design factors include:

       •      Beam uniformity across the wall surface

       •      Sharp cut-off at the top edge

       •      Resistance to outdoor environmental conditions

       •      Compatibility with various mounting distances

Our wall washer optics are designed using application-specific simulations and validated in real projects.
