Development case 1
Lens for power window switches
Illuminate 7 switches with only one LED as a light source
Oshino Lamps clears the high demand mission。
The space is extremely limited around the power window switches in an automotive. This application requires that the sections that need to be illuminated are separated over other parts and the each lighting area of the lens is small.
Also, parts of the switches are push buttons that stay at high or low position, and maintaining the same amount of lighting was required. We solved this challenge by designing an additional lens that can move high and low with the push button, and using the light indirectly by reflecting the light source from the base lens.
Because of this clever solution, we made it possible to reduce the number of parts used, and the number of assembly processes. Furthermore, because only one LED is used to illuminate the multiple areas, this eliminates the variations of colors.

Oshino Lamps Ltd. uses “Optis Works” which is an optical simulation software.This enables us to perform ray-trace, luminance distribution and analysis. After the simulation, the most appropriate form of light guide is created.
