## Abstract

The present disclosure relates to field of an arrangement of multiple optical elements to generate multiple beam patterns. The arrangement (100) of multiple optical elements to plurality of fasteners (112), and an optics plate (106). The array board (102) having LEDs (104) mounted thereon in a plurality of first blade patterns (124a-124d). The optics plate (106) is removably fastened to the array board. The optics plate (106) defines lenses (108) in a plurality of second blade patterns (126a-126d) and reflectors (110) in a plurality of third blade patterns (128a-128d), identical to the first blade pattern (124a-124d). The optics plate (106) is manually rotated into a first configuration to align the second blade pattern (126a-126d) with the first blade pattern (124a-124d) and into a second configuration to align the third blade pattern (128a-128d) with the first blade pattern (124a-124d) to generate multiple beam patterns.

## Claims

### Claim 1

An arrangement (100) of multiple optical elements to generate multiple beam patterns, said arrangement (100) comprising:
an array board (102) having a plurality of sets of LEDs (104) mounted thereon in a plurality of first blade patterns (124a-124d); and
an optics plate (106) configured to be removably fastened to said array board (102), said optics plate (106) defining a set of lenses (108) configured thereon in a plurality of second blade patterns (126a-126d) and a set of reflectors (110) configured thereon in a plurality of third blade patterns (128a-128d), each of said second blade patterns (126a-126d) and each of said third blade patterns (128a-128d) being similar to each of said first blade patterns (124a-124d), said optics plate (106) configured to be manually rotated into a first configuration to align said second blade pattern (126a-126d) with said first blade pattern (124a-124d) and into a second configuration to align said third blade pattern (128a-128d) with said first blade pattern (124a-124d) to generate multiple beam patterns.

### Claim 2 (depends on 1)
