Problems solved by technology

[0006] Overall, there is the problem that a simple change in the light intensity distribution or light emission characteristics of the lens is not easily possible in this way, since a corresponding change has so far necessitated the replacement of the entire optical element , resulting in a correspondingly high cost
Furthermore, considerable costs are incurred as a result of the production of the additional optical elements by injection molding, since a special tool or mold has to be produced for each alternative embodiment, which results in high costs

Embodiment Construction

[0025] As already stated, image 3 An arrangement 1 known from the prior art for emitting light is shown. The arrangement 1 for emitting light has a housing 3 which includes a light outlet opening, wherein an LED light source 4 is arranged in the housing and the light outlet opening is closed by an optical element 2 . In this case, the optical element 2 consists of a plurality of lenses 6 arranged in front of the LED light source 4 in the light emission direction. figure 1 An optical element 2 of this type consisting of a plurality of lenses 6 is shown by way of example.

[0026] figure 2 and Figure 4 Two different light emission characteristics or light intensity distribution curves of such a lens 6 in the C0 / C180 plane and thus in the transverse direction relative to the optical element 2 are shown. figure 2 The light intensity distribution curves shown are suitable, in particular, for example for shops selling goods, in which in each case shelves are arranged along t...

Abstract

The invention relates to an arrangement (1) for emitting light comprising at least one LED light source (4) and at least one lens (6) arranged in front of the LED light source (4) in the light emission direction. A reflector (7, 8) is arranged in front of the lens (6) in the light emission direction to influence the light emitted from the lens (6).

Description

technical field [0001] The invention relates to an arrangement for emitting light comprising at least one LED light source and at least one lens arranged in front of the LED light source in the light emission direction. Background technique [0002] In the case of elongated lighting devices or light-emitting arrangements used in the commercial sector, for example fluorescent lamps have hitherto often been used as light sources. Currently, the advancing development of LEDs has more and more implications, for example fluorescent lamps are being replaced by corresponding LEDs. This is primarily caused by the fact that LED light sources have significant advantages with regard to service life and energy efficiency compared to conventional lighting devices. Secondly, for example, the light intensity achievable with the help of LEDs has at the same time become sufficiently high that LED light sources can easily replace conventional light sources, such as fluorescent lamps.
