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.

In a lighting system an optical fiber includes a light incident portion, a light emerging portion, and a wavelength-converting portion. The wavelength-converting portion is provided between the light incident portion and the light emerging portion. The wavelength-converting portion contains a wavelength-converting element which is excited by excitation light and amplifies a spontaneous emission of light, having a longer wavelength than the excitation light, with an amplified spontaneous emission of light. A first light source unit makes the excitation light incident on the light incident portion. A second light source unit makes seed light, which causes the wavelength-converting element excited by the excitation light and the amplified spontaneous emission of light to produce a stimulated emission of light, incident on the light incident portion. A lighting unit, into an external space, light emerging from the light emerging portion of the optical fiber.

Apparatus and methods for deployment of fixtures. The apparatus may include a system for controlling deployed fixtures. The system may receive user commands different devices in different formats. The fixtures may be independently addressable. The fixtures may be magnetically supported by a fixture support. A brace may join two or more fixture supports without reducing space available to support fixtures. The brace may join a fixture support to a fixture support accessory. An accessory may include a variable-angle junction. The fixture may include articulating joints for controlling the direction of a beam. The fixture may include a lens having an electrically controllable beam spread angle. The fixture may be stowable in the fixture support. The fixture may be slidable along a cord to adjust a height of the fixture. The fixture may include an extendable ring. The system may coordinate motions of the fixtures to follow a target. The fixture may include an elongated board. The elongated board may include a non-polar power socket.

The present invention provides an assembling structure for LED luminaire, including a main support, at least one LED luminaire and at least one connecting part. The main support includes front faces on radial side, slide tracks on the front faces, and two side faces. The LED luminaire includes a cap-like housing and a lamp-connecting portion. The connecting part includes a first locating block provided in one slide track, a second locating block passing through each side face and provided in another slide track different from that for the first locating block, and a support body connected with the first and second locating blocks while extending far away from the main support. The support body is connected, at one end far away from the first and second locating blocks, with the lamp-connecting portion, while the connecting part and LED luminaire are pivoted with respect to the main support.
