The invention relates to a method for forming a luminaire (1), which has a trough-shaped luminaire housing (10, 110) having a region (25, 125) for accommodating illuminants, which is surrounded by a seal (40), a cover (70, 80) which spans the region (25, 125) and abuts the seal (40) in a peripherally closed manner, a frame-like holding element (50, 150), which presses the cover (70, 80) into abutment with the seal (40). For the luminaire housing (10 110), the cover (70, 80) and the holding element (50, 150), are each available in at least two different variants, which can be combined in any way, wherein in order to form the luminaire (1) according to desired output properties and/or properties with regard to heat dissipation or moisture resistance, a suitable luminaire housing (10, 110), a cover (70, 80) and a holding element (50, 150) are in each case selected and the selected components are assembled to form the luminaire (1).

A modular lighting system adapted to be installed in and illuminate an environment. The lighting system includes a first light fixture including a first canopy assembly adapted to engage a desired surface in the environment, a first light-emitting diode (LED) module, and a second LED module. The first LED module has a first connector assembly configured to mechanically and electrically connect the first LED module to the first light fixture via the first canopy assembly, the second connector assembly is configured to mechanically and electrically connect the second LED module to the first LED module, and the first LED module is interchangeable with a third LED module including a third connector assembly configured to mechanically and electrically connect the third LED module to both the second LED module and the first light fixture via the first canopy assembly.

Example embodiments provide lighting fixture mounting kits for mounting a flat panel lighting fixture to a mounting surface. The lighting fixture mounting kits may comprise a mounting portion (e.g., a mounting plate) and a lighting fixture. The mounting portion may be secured relative to a mounting surface and may comprise mounting catches. The lighting fixture may be secured relative to the mounting portion, and may comprise fixture catches configured to selectably engage the mounting catches. The lighting fixture may be slidable relative to the mounting portion between an engaged configuration in which the fixture catches are engaged with the mounting catches; and a disengaged configuration in which the fixture catches are disengaged from the mounting catches. When in the disengaged configuration, the lighting fixture is pivotable away from the mounting portion to facilitate access to a back portion of the lighting fixture.

The present invention relates to an optical device that enables the projection of the light to be controlled such that it comes out parallel to a non-active multi-cell shielding device, wherein said shielding device is not illuminated by the light beam, the user perceiving the light with all its intensity, without loss of intensity due to the reflection of said shielding device, wherein furthermore, due to the low profile thereof, the optical device enables same to be integrated into a luminaire with a reduced height dimension, which is also object of the present invention.

An improved dimming apparatus is disclosed. Major economies are achieved by the ability to distribute groups of dimmers in proximity to the lamp loads that they control. Variations in the location and distance between the apparatus and lamp loads, as well as in the differing connector types installed on such loads, are addressed by terminating the six power stages contained in a common enclosure in a six-circuit multi-pole connector, such that a variety of prior art “break-out” adaptors between said multi-pole connector and individual circuit connectors can be selected among. The power input to the enclosure can be made re-configurable.

An organic light-emitting diode comprising an organic layer sequence, a radiation exit area and an encapsulation. The organic layer sequence comprises at least one radiation-emitting region which generates electromagnetic radiation in the spectral range from infrared radiation to UV radiation during operation. The radiation exit area is structured, so that the electromagnetic radiation has a directional emission profile. The encapsulation forms a seal of the organic layer sequence against environmental influences.

A lens system for LED based light fixtures having a substantially coplanar array of LED's with a requirement for a wide angle of illumination. And in particular, light fixtures comprising LED lights used in low bay applications.
