Luminaire

A modular LED light for explosive areas includes a housing module including a central power supply module, at least one LED module receiving element, and an LED power supply interface arranged in the LED module receiving element such that the LED power supply interface is in the housing module. At least one LED module is configured to be detachably attached to the housing module. The LED power supply interface supplies electrical power to the at least one LED module when the at least one LED module is attached to the housing module in a usage positon.

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.

Explosion-proof housing and method for producing the same

A modular LED light, in particular for explosive areas, has at least one LED module and one central power supply module. At least the LED module is detachably attached to a housing module. The housing module has two arrangement planes in the vertical direction, wherein at least power supply connectors for the LED lights and connection lines to the central power supply module and to the LED module are arranged in the upper arrangement plane and the LED module and a driver device on an LED module receiving element or on the central power supply module are arranged in the lower arrangement plane. The housing module has at least one LED module receiving unit that is arranged lateral to the central power supply module and in which an LED power supply interface for supplying electrical power to the LED module in its usage position is arranged in the LED module receiving element.

The invention relates to an explosion-proof housing and to a method for connecting a housing part and a cover part, wherein the housing is formed at least from a metal housing part with at least one housing opening and/or receiving surface and a support edge which borders said housing opening and/or receiving surface and with a cover part which covers the housing opening or receiving surface and comprises a peripheral cover edge. The cover part and the housing part are connected together in an explosion-proof manner. In order to improve such a housing such that a corresponding connection of the housing part and cover part can be produced in a simple and secure manner without the use of adhesive in order to form an explosion-proof housing and such that the housing part and the cover part have a high degree of connection stability, a plurality of connection points between the support edge and the cover edge is formed as interlocking depressions and protrusions, the protrusions being formed by partial melting the cover edge.
