Window for a vehicle comprising a light scattering layer configured to redirect light from a purality of light emitting diodes
First Claim
1. A window for a vehicle, the window comprising:
- first and second glass substrates;
a plurality of light emitting diodes (LEDs) provided between the first and second glass substrates, wherein the light emitting diodes (LEDs) are configured to emit light toward a central area of the window;
a light scattering layer provided between the first and second glass substrates, the light scattering layer comprising light scatterers, the light scatterers configured and arranged in the light scattering layer and relative to the light emitting diodes (LEDs) so that light received from the LEDs is to be redirected in a direction substantially normal to major surfaces of the first and second glass substrates.

Abstract
Certain example embodiments relate to a vehicle window (e.g., sunroof). Side-firing LEDs are provided between first and second substantially parallel substrates and emit light towards central regions of the window. A liquid-crystal inclusive switchable film is provided between the first and second substrates. The liquid crystals are sized such that light received from the LEDs is redirected in a direction substantially normal to major surfaces of the first and second substrates. The switchable film is operable in at least first and second modes, with the window in the first mode having a visible transmission of less than 1%, and with the window in the second mode having a visible transmission of 7-15%. The switchable film and the LEDs are operable independently of one another in connection with the LEDs emitting light and the switchable film controlling visible transmission therethrough.
