## Abstract

A lighting device or lamp having two or more operating modes are provided. The lighting device or lamp comprises a housing having one or more light emitting diode (LED) packages mounted therein. The lighting device or lamp further comprises at least one secondary optic disc comprising a plurality of secondary optical elements. The secondary optical elements comprise two or more types of secondary optical elements. An operating mode of the two or more operating modes corresponds to each of the one or more LED packages being aligned with a secondary optical element of a predetermined type. The secondary optic disc is mounted to the housing so that the secondary optic disc is selectively rotatable with respect to the housing.

## Claims

### Claim 1

A lighting device or lamp comprising:
a plurality of light engines distributed in a ring arrangement;
at least one secondary optic disc comprising a plurality of secondary optical elements, the plurality of secondary optical elements comprising at least two types of secondary optical elements;
a housing, wherein the plurality of light engines are mounted within the housing; and
a selector positioned exterior to the housing and configured to rotate the secondary optical element, the selector comprising two or more predetermined selector positions, each position corresponding to alignment of at least a portion of the plurality of light engines with a corresponding type of secondary optical element of the at least two types of secondary optical elements,
wherein:
a center point of the ring arrangement and a center point of the secondary optic disc define an optical axis of the lighting device or lamp,
the ring arrangement and the at least one secondary optic disc are rotatable with respect to one another about the optical axis,
alignment of at least the portion of the plurality of light engines with secondary optical elements of a first type of the at least two types of secondary optical elements causes light emitted by the lighting device or lamp to have at least one of a first beam angle or a first beam profile in a plane that is transverse to a direction of propagation of the light,
alignment of at least the portion of the plurality of light engines with secondary optical elements of a second type of the at least two types of secondary optical elements causes the light emitted by the lighting device or lamp to have at least one of a second beam angle or a second beam profile in the plane that is transverse to the direction of propagation of the light, and
the first beam angle is different from the second beam angle and the first beam profile is different from the second beam profile.

### Claim 2 (depends on 1)

The lighting device or lamp of claim 1, wherein the selector is operably connected to an axle, the axle being affixed to the secondary optic disc such that movement of the selector from a first selector position of the two or more selector positions to a second selector position of the two or more selector positions causes rotation of the secondary optic disc with respect to the ring arrangement from a first position corresponding to the alignment of at least a portion of the plurality of light engines with the secondary optical elements of the first type to a second position corresponding to the alignment of at least a portion of the plurality of light engines with the secondary optical elements of the second type.

### Claim 3 (depends on 2)

The lighting device or lamp of claim 2, wherein the axle is affixed directly to the selector, and wherein the selector is positioned on the optical axis.

### Claim 4 (depends on 2)

### Claim 9 (depends on 8)

The lighting device or lamp of claim 8, wherein (a) the secondary optical elements of the first type correspond to a first beam angle, the secondary optical elements of the second type correspond to a second beam angle, and the secondary optical elements of a third type of the three types of secondary optical elements correspond to a third beam angle, (b) the first beam angle is within a predefined angle from the range of 5 to 45°, (c) the second beam angle is within a predefined angle from the range of 35 to 80°, and (d) the third beam angle is within a predefined angle from the range of 70-120°.

### Claim 10 (depends on 1)

The lighting device or lamp of claim 1, wherein the selector comprises positioning teeth that are configured to maintain a selected position of the two or more predetermined selector positions.

### Claim 11 (depends on 10)

The lighting device or lamp of claim 10, wherein the one or more positioning teeth are configured to rotate with the selector.

### Claim 12 (depends on 1)

The lighting device or lamp of claim 1, wherein at least one of the plurality of light engines is mounted within the housing such that light emitted by the at least one of the plurality of light engines is emitted in a direction toward the secondary optic disc.

### Claim 13 (depends on 1)

The lighting device or lamp of claim 1, wherein an axis of the housing is aligned with the optical axis of the lighting device or lamp.

### Claim 14 (depends on 1)

The lighting device or lamp of claim 1, wherein each optical element of the first type is neighbored by at least one optical element of the second type.
