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.

Modular LED light

The invention relates to electrical/electronic equipment, such as a high-powered lamp, switching device, control device, transformer, signaling device, display device, or the like, having a housing () and at least one cooling fluid supply apparatus () arranged in the housing or allocated thereto. Said cooling fluid supply apparatus has a cooling fluid inlet apparatus and a cooling fluid discharge apparatus on the housing and a cooling fluid guide apparatus within the housing. In order to improve such equipment such that safe actuating of the equipment is possible, together with a compact and competitive design, with simultaneously efficient cooling, in particular also in potentially explosive areas, at least the cooling fluid inlet apparatus is allocated a safety switching apparatus for interrupting the cooling fluid supply, in particular in the case of a pressure drop in the cooling fluid. The invention also relates to a corresponding method.

Electronic component and method for cooling

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.

LED module

An explosion-proof LED module has at least one light-emitting diode, a heat sink connected to this and an LED cover that covers the LED at least in the emission direction. The LED cover extends into an insertion recess of the heat sink. In this insertion recess, the LED cover is surrounded by a casting compound resulting in sealing of the LED relative to an outer and possibly explosive atmosphere. As a result, an explosion-proof LED module can be provided whereby the manufacture of said explosion-proof LED module is relatively simple and possible in an economic manner in a short time from prefabricated parts. At the same time, the explosion-proof module is furthermore characterized in that sufficient cooling corresponding to the ignition protection type 'intrinsic safety' and an embedding of the component according to ignition protection type 'encapsulation' are given.

Explosion-proof LED module

An explosion-proof luminaire comprises a plurality of light-emitting diodes. These are assigned to a ballast for electrical power supply. A contactless power transmission device is formed between at least a group of LEDs and the ballast. This yields an explosion-proof luminaire which is simplified and improved in terms of structure and light output while permitting many possible arrangements of the LEDs in the corresponding luminaire at the same time.

Explosion-proof lamp

A lamp has a plurality of LEDs which are arranged behind one another in the lamp's longitudinal direction and in LED spacing by means of an LED carrier. Each LED emits light in a certain solid angle area around a beam center direction. The solid angle area is directed towards a lamp reflector for indirect light emission of the lamp. The number of LEDs and/or the LED spacing is selected in such a way that the solid angle areas of all LEDs after reflection at the light reflector overlap at least partially at an illumination surface distance from an underside of the lamp of at least 0.2 to 2.5 times the distance between the LEDs that are spaced the farthest apart from each other.
