AI Technical Summary
Technical Problem
Existing signal lighting devices experience inhomogeneous light emission due to multiple light deflections, leading to loss of light intensity and non-uniform luminous output.
Method used
The device incorporates optical structures along the first light guide channel to deflect light rays such that they become more parallel to the main emission direction, ensuring uniform light intensity across the output coupling area by reducing angles between light rays and the emission direction through total internal reflection and prismatic deflections.
Benefits of technology
Achieves homogeneous light emission by aligning light rays to be parallel to the main emission direction, resulting in a uniformly bright output surface with consistent light intensity.
