Brightness of products

Indirect illumination is mostly used for ambient illumination to create mood. The light source is mostly invisible and illuminates surfaces. The illumination of the surface from the top or side highlights the structure in a decent way. Because we reflect light on a surface the perceived brightness diminishes with the reflection behaviour of this surface.  In comparison a direct illumination is when you directly see the last surface of the light system, usually a diffuse plastic element. This element covers the surface, give a haptic end user experience, hides the technology and fixation elements that could be perceived as brightness spots. Direct visible light lines and areas are usually brighter than indirect ones because the light system is more efficient. For this the ambient illumination is mostly used to be seen in darker environment conditions while the direct illumination can be seen during daylight. With high power LED or LED stripes the ambient illumination can become functional as well to create warnings or display the product state.

06/2022 Wiki "light simulation" released (german language)

06/2022 Ambient light systems and avoidable errors in current products

  • Scouting the market for good and bad light in products

  • Sony has prism light guides in his new smart speakers, cool to see the daytime running light automotive appearance and not just uniform light
  • ambient light can be great looking in all products but tiny things in the product will create visible spots, dark areas or unwanted appearance in many other ways. Avoidable during development with knowledge and light simulation as checking tool.

05/2022 Development of light in toys started

  • light simulation & knowledge to create the next generation. More power efficient, more cost efficient and more uniform light in products

  • when the products hit the market we will publish more infos
