## Abstract

An arrangement for emitting light having at least one LED-light source and at least one first lens arranged in front of the LED light source in the light-emitting direction, wherein a second lens is arranged in front of the first lens in the light emitting direction for influencing the light emitted from the first lens.

## Claims

### Claim 1

An arrangement for emitting light comprising at least one LED light source and at least one first lens arranged in front of the LED light source in the light emission direction, wherein a second lens for influencing the light emitted from the first lens is arranged in front of the first lens in the light emission direction.

### Claim 2 (depends on 1)

The arrangement for emitting light as claimed in claim 1, wherein the light intensity distribution curve of the light emitted from the first lens in the C0/C180 plane has two substantially symmetrical, mutually separate wings which lie in each case substantially in an angular range of 0° to 90° relative to an axis parallel to the light emission direction through the light centroid of the first lens and have in each case a peak region and flank regions adjacent thereto on both sides, on which flank regions the light intensity falls to a significantly lower value than in the peak region, wherein the peak region lies at angles of greater than 0° and one of the flanks falls toward the angular range around 0°, wherein the angle between the two peak regions of the wings corresponds to the aperture or emission angle of the light emitted from the first lens.

### Claim 3 (depends on 1)

The arrangement for emitting light as claimed in claim 1, wherein the aperture or emission angle of the light emitted from the first lens is greater than 0°.

### Claim 4 (depends on 1)

The arrangement for emitting light as claimed in claim 1, wherein the second lens is designed and arranged in front of the first lens in such a way that the aperture or emission angle of the light emitted from the first lens is reduced by the second lens.

### Claim 5 (depends on 1)

The arrangement for emitting light as claimed in claim 1, wherein the second lens is designed and arranged in front of the first lens in such a way that the aperture or emission angle of the light emitted from the first lens is increased by the second lens.

### Claim 6 (depends on 1)

The arrangement for emitting light as claimed in claim 1, wherein the arrangement for emitting light has a plurality of LED light sources and a plurality of first lenses wherein the first lenses are joined together to form an optical element.

### Claim 7 (depends on 6)

The arrangement for emitting light as claimed in claim 6, wherein in each case exactly one first lens of the optical element is assigned to each LED light source.

### Claim 8 (depends on 6)

The arrangement for emitting light as claimed in claim 6, wherein second lenses are assigned only to a portion of the first lenses.

### Claim 9 (depends on 1)

The arrangement for emitting light as claimed in claim 1, wherein the arrangement for emitting light has a housing having a light exit opening, wherein the at least one LED light source is arranged in the housing and the at least one first lens closes the housing in the light emission direction.
