Embodiment Construction

[0039] figure 1 A schematic diagram of an optical module 10a according to a first embodiment of the present invention is shown. The light module 10a has an excitation radiation source 12 which can in particular comprise a blue laser and / or one or more laser diodes which emit excitation radiation 14 in particular in the blue spectral range between 440 nm and 480 nm. Furthermore, the light module 10 a has a color wheel 16 , which is rotatable about an axis of rotation A, in particular at a constant rotational frequency.

[0040] The color wheel 16 is in figure 2 is shown in top view, ie in a plane perpendicular to the axis A of rotation. The color wheel 16 can be divided into two regions, a first outer region B1 and an inner second region B2 , which should be illustrated by a boundary line 17 between these two regions B1 and B2 . Furthermore, the color wheel 16 has a plurality of sectors, here by way of example eight sectors 16a, 16b, 16c, 16d, 16e, 16f, 16g and 16h.

Abstract

The invention relates to an optical module (10a; 10b; 10c) with an excitation radiation source (12), a light module (16a; 16b; 16c; 16d; 16e; 16f; 16g; 16h; 40a; 40b ; 40c; 40d; 40e; 40f; 40g; 40h) of the rotatable color wheel (16; 40), the sector can be sequentially irradiated by the excitation radiation source (12) when the color wheel (16; 40) rotates According to. Here, in the first area (B1) at least in the sector (16a; 16b; 16c; 16d; 16e; 16f; 16g; 16h; 40a; 40b; 40c; 40d; 40e; 40f; 40g; 40h) A wavelength conversion element (18; 20; 42) is arranged in one. Furthermore, at least one subregion (24) of the second region (B2) of the color wheel (16; 40) is at least partially designed to be transparent to light emitted by the at least one wavelength conversion element (18; 20; 42) An output (26) of the light module (10a; 10b; 10c) can be guided through the subregion (24).

Description

technical field [0001] The invention is based on a light module for generating wavelength-converted light. The light module has an excitation radiation source for generating excitation radiation having at least one wavelength in a first wavelength range, a color wheel rotatable about an axis of rotation, the color wheel being divided into first regions (B1) and a second area, said first area and said second area do not overlap and are mutually arranged in a radial direction such that one of these two areas is an inner area of ​​said color wheel, and this One of the two regions is an outer region of the color wheel, wherein the color wheel has a plurality of sectors, wherein in the first region at least one of the sectors of the color wheel is provided There is a wavelength conversion element designed to convert radiation having a wavelength in a first wavelength range into light having a dominant wavelength in a second wavelength range different from the first wavelength rang...
