Abstract

Light emission device (1) comprising: - at least one emission module (ME) comprising: - a luminescent crystal called a concentrator crystal (CL) having at least six parallel faces in pairs, including a first and a second face called lateral faces (FL1, FL2) perpendicular to a direction x and separated by a distance L corresponding to a horizontal dimension of said concentrator in the direction x; - a first mirror (M1) configured to at least partially cover said first lateral face (FL1), defining a surface covered (SR1) by said first mirror and at least one surface not covered (SFS1) by said first mirror defining an associated output face (FS1, FS1<1>, FS1<2>), - a second mirror (M2) configured to cover at least 95% of said second lateral face (FL2), - a luminescence trigger element (ED) adapted to generate an emission of luminescence radiation (LF) in said luminescent crystal; a ratio R between the uncovered surface (SFS1) and a surface (SL) of the first lateral face (FL1) being determined so that rays of the luminescence radiation are reflected on said first and second mirrors and propagate over an average distance Lmoy » L within the luminescent crystal before crossing at least one output face (FS1<1>, FS1<2>), forming an output beam (Lout).
