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).

Lighting systems that include an LED and a silicone module designed to contain a lens are described herein.

The present disclosure relates to a molded article provided with a resin part formed with a thermoplastic resin composition. The molded article is provided with a resin part formed with a thermoplastic resin composition. The thermoplastic resin composition containing a thermoplastic resin, cellulose, and an ionic compound, wherein a content of the cellulose is 1 to 100 parts by mass based on 100 parts by mass of the thermoplastic resin, and a content of the ionic compound is 0.001 times or more and less than 1.000 times the content of the cellulose.

The present invention relates to lighting fixtures which are mounted into architectural finished surfaces such as ceilings, walls and floors, and is applicable to new installations as well as the renovation of existing surface-mounted fixtures. One embodiment relates to a modular lighting device for retro-fitting to an existing lamp housing which is flush mounted or countersunk into an opening of a ceiling or interior surface of a building, the modular lighting device comprising a lamp-fitting configured for receiving a light source and configured for attachment to the existing lamp housing, and reflector for reflecting and/or modifying light from the light source, the reflector comprising a narrow top section configured for attachment to said lamp-fitting, and a wider bottom section for covering said opening.

An explosion-proof housing includes at least one metal housing part having at least one of a housing opening or receiving surface, and a support edge bordering said at least one of a housing opening or receiving surface. A cover part covers said at least one of a housing opening or the receiving surface. The cover part includes a peripheral cover edge which is connected to the support edge in an explosion-proof manner such that in the event of an explosion inside the housing, the explosion is prevented from crossing over to an explosive atmosphere surrounding the housing. A plurality of connection points are formed between the support edge and the cover edge. The connection points include interlocking depressions and protrusions. The protrusions are formed by partial melting of the cover edge. The depressions and the protrusions interlock with play in a longitudinal direction of the housing.

A modular system may include a plurality of magnets that may be provided to self-align a casing with an accessory. Self-alignment of the casing and the accessory may provide a secure connection of the casing with the accessory. At least one detent and at least one locking arm may mate and lock the casing against the accessory in a mounted position. The at least one detent and the at least one locking arm may unlock in an insertion position. Self-alignment may occur when a first set of magnets attracts a second set of magnets in which opposite polarities attract and automatically initiate movement of the casing towards the accessory.
