1. A modular construction system light matrix comprising:
a housing having side walls, an end wall and a front edge encircling a front opening of said housing opposite to said end wall;
an array of light emitting elements arranged on a printed circuit board, the printed circuit board being arranged in said housing;
a compartment grid arranged in said housing, and having compartment grid walls extending from said printed circuit board towards said front opening of the housing, and forming an array of compartments, one compartment for each light emitting element; and
a light diffusing element arranged at said opening of the housing,
wherein the diffusing element comprises a plurality of diffuser tiles, each diffuser tile for covering a compartment of the compartment grid,
wherein each diffuser tile has a front surface, a back surface and sidewalls formed perpendicularly to the front surface,
wherein the diffusing element comprises a diffuser grid providing a barrier between mutually facing sidewalls of the diffuser tiles,
wherein the diffuser grid is formed in a material different from a material of the diffuser tiles, and
wherein a lower side of the diffuser grid is adapted to abut against an upper side of the compartment grid, to prevent light bleeding between the array of compartments.
