Title (EN) MULTI-MODE ILLUMINATION MODULE AND RELATED METHOD
(FR) MODULE D’ÉCLAIRAGE MULTIMODE ET PROCÉDÉ ASSOCIÉ
Abstract:
(EN) The illumination module for emitting light (5) can operate in at least two different modes, wherein in each of the modes, the emitted light (5) has a different light distribution. The module has a mode selector (10) for selecting the mode in which themodule operates, and it has an optical arrangement. The arrangement includes - a microlens array (LL1) with a multitude of transmissive or reflective microlenses (2) which are regularly arranged at a lens pitch P (P1); - an illuminating unit for illuminating the microlens array (LL1).The illuminating unit includes a first array of light sources (S1) operable to emit light of a first wavelength L1 each and having an aperture each. The apertures are located in a common emission plane which is located at a distance D (D1) from the microlens array (LL1). In a first one of the modes, for the lens pitch P, the distance D and the wavelength L1 appliesP2 = 2⋅L1⋅D/N wherein N is an integer with N ≥ 1.
(FR) Le module d’éclairage de l’invention, servant à émettre une lumière (5), peut fonctionner dans au moins deux modes différents, la lumière émise (5) présentant dans chacun des modes une distribution de lumière différente. Le module comporte un sélecteur de mode (10) servant à sélectionner le mode dans lequel le module fonctionne, et il comporte un agencement optique. L’agencement comprend : un réseau de microlentilles (LL1) comprenant une pluralité de microlentilles (2) transmissives ou réflectives qui sont agencées régulièrement suivant un pas de lentille P (P1) ; une unité d’éclairage servant à éclairer le réseau de microlentilles (LL1). L’unité d’éclairage comprend un premier réseau de sources de lumière (S1) conçues pour émettre chacune une lumière d’une première longueur d’onde L1 et ayant chacune une ouverture. Les ouvertures sont situées dans un plan d’émission commun qui est situé à une distance D (D1) du réseau de microlentilles (LL1). Dans un premier mode, pour le pas de lentille P, la distance D et la longueur d’onde L1 vérifient P2 = 2⋅L1⋅D/N, où N est un entier et N ≥ 1.
