Description

The invention generally relates to a particularly easily remodeling light, so a lamp that can be particularly easily redesigned both for use as ceiling, surface-mounted, built-in, Wandanbau- and as a pendant.

State of the art

In particular, the invention relates to a luminaire with a gear device comprehensive equipment for mounting on a developer, a lamp body with a comprehensive LED bulbs, and a lamp cover for covering and / or glare generated by the LEDs luminous flux or cover of the lamp body. Device carrier and lamp body incl. Luminaire cover represent insofar assemblies that can be combined with each other differently, a luminaire either as a surface-mounted luminaire below a developer, as a recessed luminaire inserted into an enclosing element, e.g. a suspended ceiling as a wall or as a pendant, so with a ceiling mount, a wire suspension and the hanging hanging on the wire suspension lamp body.

The device carrier is often used as a light housing denotes and includes the electrical and / or electronic devices for operating the lamp, so ballasts, terminals, etc. In the present case, the lamp body and the ring together form the lamp.

The US 2011/0242815 A1 discloses a lamp for LED with a heat sink, a removable insert with LED light source and a heat sink engaging on the retaining part, which can hold a lampshade, for example.

Disadvantages of the prior art

Known lights are usually determined for the particular installation situation or determined for a particular installation situation either as built-in or surface mounted pendant lamp and must be elaborately redesigned according to the particular installation situation by the operating devices are arranged at different locations in the lamp. This is time-consuming and costly, because it also increases the number of variants and thus the storage costs.

Technical problem / task

Based on this prior art, the present invention seeks to at least partially avoid these disadvantages and in particular to provide a luminaire, which allows a simple change to different types of luminaires, ie as a growing, wall mounted, recessed or pendant.

invention

According to the invention this object is already in a luminaire of the type mentioned by the features of characterizing part of the independent claims. Advantageous further developments are given in the subclaims.

According to the invention this is achieved in that a separable from the lamp body mounting body is provided, which is connectable to the developer and includes the necessary for the operation of the LEDs operating equipment, so the entire electrical and / or electronic functions of the lamp takes over. This makes it possible to integrate the luminaire ring or the luminaire body, which realizes the light function, without reshaping with the various solution concepts. The lamp body is preferably designed as a heat sink for the removal of the heat generated by the LEDs, which is particularly preferably carried out by training as a metal profile, because of the low weight particularly preferably as an aluminum profile.

In the simplest embodiment, the device carrier and the lamp body are thus designed to either together with each other built as surface or recessed lighting designed or separated from each other as a pendant.

Another feature of the invention is the multifunctional design of the connection element or the connection areas of the lamp body, which realize several functions simultaneously, namely the mechanical connection function to the mounting body, the electrical connection function to the operating devices, the electrical connection function between different segments of the LED modules and the mechanical locking of the lamp cover to the lamp body. Preferably, the connection element can be closed by a detachably fastened connection cover, which is preferably also designed such that it realizes the locking of the luminaire cover.

In a preferred embodiment, the lamp body is formed as a lamp ring, which consists of an annular, closed aluminum profile that receives LED modules on its underside and on its upper side fastening means or connecting means for connection to the equipment carrier and an enlarged free Has surface to improve the cooling performance. Furthermore, a luminaire cover acting as an optic is usually fastened to the underside, which can consist of a translucent plastic body, for example, which transforms the point-type light generated by the LEDs into diffused light.

The luminaire according to the invention can thus be converted from a ceiling luminaire into a pendant luminaire simply and virtually without tools, in which the luminaire body is separated from the mounting body (device carrier), e.g. by a rotation and thereby releasing a bayonet lock and then led out of the assembly body as three cables acting as cables and mechanically and electrically connected to the lamp body. In this case, the first line can form the phase, the second line the neutral conductor and the third cable the protective conductor or the fall protection, in that the protective conductor is screwed to the housing with an eyelet. In this embodiment, the mounted on the ceiling mounting body thus acts like a canopy, from which extend the lines to the lamp body.

The lamp may for this purpose have an automatic return device for the ropes, so that the height of the lamp body in relation to the mounted on the ceiling mounting body can be easily changed.

A separate aspect of this invention is the particular strain relief that combines multiple functions in a particularly small and compact component. On the one hand, this closes the connection area. Furthermore, this acts as a backup for the lamp cover against unwanted loosening. The light cover can be connected to the light ring eg via a bayonet lock. In the installation position, the connection region comprises a blocking element, preferably designed as a blocking nose, which engages in the closed position in a counter-element, for example a correspondingly formed undercut on the lamp cover and this fixed inextricably in the desired position.

In order to reduce the rejects during production, the board is divided into three segments which, when assembled, form the closed ring adapted to the structure of the lamp body. For the connection technology or the supply technology, this means that electrical terminals are provided for connecting the individual ring segments to one another at the joints in the connection areas.

Several preferred embodiments of the invention are shown by way of example and not limitation in the drawings and will be described in more detail below.
