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.
Claims18
A lighting device or lamp having two or more operating modes, the lighting device or lamp comprising:
- a housing having one or more light emitting diode (LED) packages mounted therein, at least a portion of the one or more LED packages being distributed in a ring arrangement;
- and
- 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, wherein at least a portion of the plurality of secondary optical elements are distributed in a ring arrangement in an alternating pattern;
- wherein:
- 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, and
- each operating mode is defined by at least one of a beam angle or a beam profile, the plurality of secondary optical elements of the at least one secondary optic disc are configured to define the at least one of the beam angle or the beam profile of each operating mode, the beam profile describing the intensity of light at points along a diameter of a beam of light emitted by the lighting device or lamp in a plane that is transverse to a direction of propagation of the beam of light.
A lighting device or lamp having two or more operating modes, the lighting device or lamp comprising:
- a housing having one or more light engines mounted therein, at least a portion of the one or more LED packages being distributed in a ring arrangement;
- and
- at least one secondary optic disc comprising a plurality of secondary optical elements, the secondary optical elements comprising two or more types of secondary optical elements, at least a portion of the plurality of secondary optical elements being distributed in an alternating pattern in a ring arrangement;
- wherein:
- an operating mode of the two or more operating modes corresponds to each of the one or more light engines 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 moveable with respect to the housing,
- movement of the secondary optic disc from a first position to a second position causes a switching of the operating mode of the lighting device or lamp from a first operating mode to a second operating mode, and
- each operating mode is defined by at least one of a beam angle or a beam profile, the plurality of secondary optical elements of the at least one secondary optic disc are configured to define the at least one of the beam angle or the beam profile of each operating mode, the beam profile describing the intensity of light at points along a diameter of a beam of light emitted by the lighting device or lamp in a plane that is transverse to a direction of propagation of the beam of light.
