Problems solved by technology

[0004] However, such fixing of the optical element on the printed circuit board does not have the desired accuracy, especially of the relative position of the lens with respect to the light source.
As a result, the lighting characteristics of the lighting device may deviate from the desired lighting characteristics to an undesired degree

Embodiment Construction

[0068] figure 1 Shown for the production of lighting device 2 (see figure 2 ) Schematic block diagram of device 1. The device 1 comprises at least one SMD placement device 3 . The optical element embodied as an aspherical lens 4 can be positioned on the radiation source 5 embodied as an LED by means of the SMD mount device 3 . For this purpose, the SMD placement device 3 comprises a movable part 6 . The movable part 6 is movable to a storage device 7 of the optical element 4 , wherein the storage device 7 can be embodied, for example, as a belt, or as a tray, or as a blister. The movable part 6 can grip or pick up the optical element 4 from the storage device 7 by means of a vacuum gripping device 8 . The optical element 4 grasped in this way can then be transported to a radiation source 5 arranged on a printed circuit board 9 . In this case, a plurality of radiation sources 5 are arranged on a printed circuit board 9 . Furthermore, the optical element 4 is arranged by ...

Abstract

The invention relates to a method and a device for producing a lighting device (2, 16), comprising at least the following method steps: - providing a radiation source (5), - providing an optical element (4), - the optical element (4) Arranged in the desired spatial position relative to the radiation source (5), wherein the optical element (4) is positioned in the desired spatial position by the SMD patch device (3), wherein, in the Before and / or during the process of arranging the optical element (4) in the desired spatial position, an optical connection means (15) is applied in the region of the radiation source (5).

Description

technical field [0001] It is known to produce lighting devices comprising one or more LEDs as light source. The LEDs can also be arranged on a printed circuit board by means of an automatic SMD placement machine. [0002] Furthermore, it is known to use optical elements such as lenses in order, inter alia, to shape and / or direct the light emitted by the light source in a desired manner. Furthermore, it is known to use optical elements, in particular lenses, for LEDs arranged on printed circuits. Background technique [0003] DE 10 2005 051 807 A1 and DE 10 2004 051 379 A1 disclose a printed circuit board on which an electrical device and at least one component are mounted, wherein the respective component comprises at least one holding area, the at least one holding area A constriction and a thickening adjacent thereto are included, wherein the thickening is provided in the region of a plated-through hole of the printed circuit board and is held in place by solder material...
