Abstract[English]
A micro LED projector comprise a micro LED panel(201,202,203) and a collimator unit(14). The micro LED structure in the micro LED panel(201,202,203) comprises a mesa structure and a micro lens(11) configured to collimate the ray emitted from the micro LED panel(201,202,203) to a preset objective position; the micro LED panel(201,202,203) has a light emitting area and the collimator has an input surface, the light emitted from the light emitting area of the micro LED panel(201,202,203) enters into the input surface of the collimator, so as to control the chief ray angle of the micro LED structure and reduce the loss of the light emitting from the sidewall of the mesa, and to decrease the volume and the weight of the micro LED projector.[French]
L'invention concerne un projecteur à micro-DEL comprenant un panneau de micro-DEL (201, 202, 203) et une unité de collimateur (14). La structure de micro-DEL dans le panneau de micro-DEL (201, 202, 203) comprend une structure mesa et une microlentille (11) configurées pour collimater le rayon émis par le panneau de micro-DEL (201, 202, 203) à une position d'objectif prédéfinie ; le panneau de micro-DEL (201, 202, 203) a une zone d'émission de lumière et le collimateur a une surface d'entrée, la lumière émise à partir de la zone d'émission de lumière du panneau de micro-DEL (201, 202, 203) pénètre dans la surface d'entrée du collimateur, de manière à commander l'angle de rayonnement principal de la structure de micro-DEL et à réduire la perte de la lumière émise par la paroi latérale du mesa, et pour diminuer le volume et le poids du projecteur à micro-DEL.
