CA 2632707

The invention specifies a light-emitting diode module (20) having at least two light-emitting diode chips (1), a memory unit (2), in which values for the brightness and the color locus of each light-emitting diode chip (1) are stored, and a control unit (3), which is suitable for controlling an operating current through each light-emitting diode chip (1) as a function of the stored values. Such a light-emitting diode module (20) makes particularly precise and reproducible white point representation possible. Furthermore, the invention specifies a method for producing a light-emitting diode module (20) and an optical projection apparatus having such a light-emitting diode module (20).

La présente invention concerne un module (20) de diodes électroluminescentes avec au moins deux puces (1) de diodes électroluminescentes, une unité d'enregistrement (2), dans laquelle des valeurs pour la clarté et le coloris de chacune des puces (1) de diodes électroluminescentes sont enregistrées, et une unité de commande (3) qui convient pour commander un courant de fonctionnement à travers chacune des puces (1) de diodes électroluminescentes en fonction des valeurs enregistrées. Un tel module (20) de diodes électroluminescentes permet une représentation de points blancs particulièrement exacte et reproductible. L'invention concerne en outre un procédé de fabrication d'un module (20) de diodes électroluminescentes ainsi qu~un dispositif de projection optique comportant un tel module (20) de diodes électroluminescentes.
