Light generating system with triangular light guide panel

Abstract

The invention provides a light generating system (1000) comprising a lighting arrangement (100) of a triangular light guide panel (130) and a light source arrangement (110), wherein: the triangular light guide panel (130) comprises a first triangular face (136) and a second triangular face (139), wherein the triangular light guide panel (130) further comprises a first side face (131), a second side face (132), and a third side face (133), 5 bridging a distance (d1) between the first triangular face (136) and the second triangular face (139), wherein the first side face has a first length (L1); the light source arrangement (110) comprises a plurality of light sources (10) configured in an array (115) aligned with the first side face (131), wherein the light sources (10) are configured to provide light source light (11) having a luminous flux, wherein the light sources (10) comprise solid state light sources; 10 the triangular light guide panel (130) comprises light outcoupling elements (120), wherein the light outcoupling elements (120) are arranged in the triangular light guide panel (130), and/or on the first triangular face (136), and/or on the second triangular face (139); and wherein the light outcoupling elements (120) are configured to facilitate light outcoupling from the triangular light guide panel (130); the light source arrangement (110) and the 15 triangular light guide panel (130) are configured such that in a first operational mode of the light generating system (1000) (a) at least part of the light source light (11) enters the triangular light guide panel (130) via the first side face (131) to provide incoupled light source light (12), wherein the triangular light guide panel (130) is configured to guide the incoupled light source light via total internal reflection, and (b) at least part of the incoupled 20 light source light (12) is coupled out from the triangular light guide panel (130) via the first triangular face (136); a density of the light outcoupling elements (120) increases with increasing normal distance (ND) from the first side face (131); and in the first operational mode, the light source light (11) incident on the first side face (131) has a luminous flux gradient along at least 20% of the first length (L1).
