Problems solved by technology

If the different emission characteristics of the optical body are associated with specific light-emitting diodes, for example by means of a Fresnel lens, then there is a considerable installation effort for up to 1000 light-emitting diodes for the lighting unit, in particular due to the need for sorting

Embodiment Construction

[0026] exist figure 1 An optical array 14 is shown in , and has a carrier plate 15 in which, for example, twelve optical bodies 12 are accommodated. These optical bodies 12 are shown by way of example from the front side, which reflects the exit side for the light exit of the optical array. In order to fasten the optical array 14, for example on several spacer bolts, in particular for the arrangement in front of the printed circuit board and thus on the heat sink of the lighting unit, a plurality of mounting holes 18 are introduced in the carrier plate 15, said mounting holes exemplarily The ground is introduced into the carrier plate 15 in the middle region between the optics bodies 12 . The exemplary embodiment shows a total of six mounting holes 18 through which fastening elements, for example screw elements, can be passed in order to fasten the optical array 14 to spacer screws.

Abstract

The invention relates to a lighting unit (1) for a device for identifying foreign parts during spinning preparation, said lighting unit (1) comprising a plurality of light emitting diodes (10) at least indirectly arranged on at least one circuit board (11) and configured to irradiate into an inspection channel of the device through which fibre material to be cleaned can be conducted, wherein an optical element (12) is associated with each of the light emitting diodes (10) and is used to shape the beam of the light (13) emitted by said light emitting diodes (10). According to the invention, a plurality of optical elements (12) form a single-piece optical array (14), wherein a plurality of optical arrays (14) are arranged in front of the light emitting diodes (10) such that each optical body(2) is associated with the light emitting diodes (10).

Description

technical field [0001] The invention relates to a lighting unit for a device for detecting impurities in a textile preparation device, wherein the lighting unit has a plurality of light-emitting diodes arranged at least indirectly on at least one printed circuit board and is designed for , irradiating light into the inspection channel of the device through which the fiber material to be cleaned can pass, and the light-emitting diodes are each associated with an optical body for beam shaping of the light emitted by the light-emitting diodes . Furthermore, the invention relates to an optical array with a carrier plate and a plurality of optical bodies for such a lighting unit. Background technique [0002] DE 10 2013 010 468 A1 discloses a device for foreign matter detection in a textile preparation device, which has a lighting unit with a plurality of light emitting devices arranged at least indirectly on at least one printed circuit board diodes, and the lighting unit is c...
