EP2363634B1 - Built-in LED light, in particular ceiling light - Google Patents

Description

The invention relates to a flush-mounted LED light, in particular ceiling light, for the electrical and mechanical connection in a commercially available flush-mounted device box, having a support plate owning flush-mounted device base, which a light source and a light source feeding converter including connection unit for 230V power lines has, wherein an additional mounting plate for fixing a lamp element is provided on the flush-mounted device base. The flush-mounted LED light is suitable for installation in a commercially available flush-mounted device box (in particular according to DIN 49073).

From the EP 1 477 726 A2 is a LED downlight known, comprising a unit with at least one LED and a power supply and fasteners for mounting the unit in a commercial electrical installation box, especially flush box. The fasteners have an attachable to the unit mounting portion and attachable to the electrical installation box attachment portion, wherein the assembly and the fasteners are adapted to the inner dimensions of an electrical installation box that the assembly together with attachable to her fasteners and together with Connection means connected mains voltage lines can be inserted into the can. The attachment is made by means of anchoring elements, such as screws.

From the DE 10 2007 017 329 A1 a luminaire for installation in buildings is known as orientation or signal light, with a housing with bulbs and pointing to a front visible side transparent cover. The housing is designed as a socket-like device insert with a frame-like support member such that the device insert is insertable into an electrical installation box while the support member is for abutment with a surrounding mounting surface, wherein the support member with a front, the visible side facing housing substantially flush in a plane. The cover can be attached to the housing via lateral clip-like holding elements.

From the DE 203 13 428 U1 is known from a mounting plate, a light-emitting diodes and possibly other electronic components printed circuit board with power supply lines, a light distribution panel and a frame with a light exit opening existing light known. The power supply lines are led to a connection box arranged essentially behind the luminaire, in which a transformer which can be connected to the power network is arranged. The connection cables of several luminaires behind a wall covering (tiles, tile mirrors) can be routed to a central connection point where a low-voltage source (transformer) is installed.

From the DE 10 2007 001 850 B3 an installation switch or button with device base, rocker and lighting is known, wherein a light guide is arranged on the back of the rocker and wherein in the device base a lamp holder is arranged with a lamp whose light radiates into a light entry surface of the light guide. The rocker has a mounted on its installation switch or button, preferably in the direction of the floor facing side edge on a light exit opening, which receives a light exit surface of the light guide, so that the floor located below the installed installation switch or button is illuminated. When designed as an installation switch with two different positions of the rocker, the lamp is turned on only in the off position of the rocker, while the lamp remains switched off in the on position of the rocker. Although the light exit opening radiates preferably in the direction of the floor, alternatively, the installation switch or -taster but also rotated by 180 ° are mounted so that the light exit opening radiates towards the ceiling, resulting in a very bright, preferably white ceiling for the reflection of the radiated light, whereby the desired floor lighting is realized.

In general, suitable for installation in a standard flush-mounted device box flush-mounted LED lights, especially ceiling lights, the problem of long-term secure attachment. In ceiling lights, a relatively high weight of the lamp body has a direct effect on the mounting and its long-term behavior.

The invention has for its object to provide a flush-mounted LED light, in particular ceiling light, which can be mounted in a simple and reliable manner in the long term.

Bei Verwendung des Rahmens 21 ist eine formschöne Einbindung / Integration der Unterputz-LED-Leuchte in ein Installationsgeräte-Programm respektive Schalter- und Steckdosenprogramm möglich.

In the FIGS. 8 and 9 views are shown on mounting plate / lamp element configurations in different embodiments of the lamp element. It is shown in each case, in which with respect to the mounting plate 10 twisted position, the lamp element 18 is placed on the mounting plate 10. This twisted position is clearly indicated by the markers 16. In this case, differently configured lamp elements 18 can be placed on one and the same mounting plate using one and the same flush-mounted device socket:

• according to Fig. 8 is the filament 19 formed in the form of an acrylic body, which is outwardly visible bordered by any frame,
• according to Fig. 9 the lamp body 19 is enclosed by a visible from the outside in the mounted position frame 21. When using the frame 21 a shapely integration / integration of the flush-mounted LED light in an installation equipment program respectively switch and socket program is possible.
