Abstract:
A light guide having a light guide body plate having a plurality of elongated light channels extending substantially parallel to each other; the light guide having an out-coupling arrangement for coupling light propagating in the light channels out of the light guide body plate through the first and/or the second main surface. In a horizontal transverse direction, each light channel is confined between two confining stripes formed of a solid confining material having a second refractive index lower than the first refractive index, confining stripes between two adjacent light channels having a height less than the thickness of the light guide body plate.

Claim (Index 10):
Method for manufacturing a light guide ( 100 ), comprising:\n providing a light guide body plate ( 110 ) having a first main surface ( 111 ) and a substantially parallel second main surface ( 112 ) opposite to the first main surface and separated therefrom in a vertical direction by a thickness of the light guide body plate, the light guide body plate being made of a light guide material having a first refractive index; forming in the light guide body plate a plurality of elongated light channels ( 120 ) extending substantially parallel to each other and to the first and the second main surfaces; and forming an out-coupling arrangement ( 140 ) for coupling light propagating in the light channels out of the light guide body plate through the first and/or the second main surface; wherein forming the plurality of elongated light channels comprises: forming a plurality of grooves ( 124 ) in the light guide body plate ( 110 ), each light channel ( 120 ) being confined, in a horizontal transverse direction, between two grooves, grooves between two adjacent light channels having a height less than the thickness of the light guide body plate so that the light guide body plate forms a continuous structure; and filling the grooves so as to form confining stripes ( 130 ) formed of a solid confining material having a second refractive index lower than the first refractive index by a refractive index difference to enable total internal reflection at interfaces ( 123 ) between the light channel and the confining stripes.
