Abstract

The flush-light emitting diode-lamp has a flush-device socket (3) with a carrier plate (5), where the flush-device socket has a light unit (4) and converter including connection unit. An additional mounting plate (10) is provided for fastening a light element at the flush-device socket. The plastic coatings are arranged at the rear sides of the mounting plate.

Description

The invention relates to a flush-mounted LED light, in particular ceiling light, for installation in a commercially available flush-mounted device box (in particular according to DIN 49073).

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 light exit opening at its mounted on the installation switch or switch, preferably in the direction of the floor side edge, which picks up a light exit surface of the light guide so that the floor below the installed installation switch or push 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 pushbutton can also be mounted rotated by 180 °, so that the light exit opening radiates towards the ceiling, which leads to 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.

In addition, the support plate with at least two receptacles 8 for plastic spacers (see reference numeral 12 in the FIGS. 2 and 3 ) Mistake.

Provided with a central recess 11 mounting plate 10 has on its back the above-mentioned plastic spacers, which have an accessible from the front of the mounting plate 10 bore 13, in which spreading means inserted, preferably mounting screws 14 are screwed. In general, two diagonally oppositely arranged receptacles 8 / plastic spacers with bores 13 are sufficient. The mounting plate 10 further has on its front side a plurality of guide / holding means 15, which serve to fasten the lamp element. In the embodiment shown are four in symmetrical manner arranged guide / holding means 15 is provided. Finally, at the edge of the front side of the mounting plate 10 a plurality of markings 16 are mounted, which facilitate the mounting of a lamp element to the mounting plate and for this purpose indicate the position at which the lamp element is to be placed on the mounting plate.

It is first the mounting plate 10 with its central recess 11 and the two arranged diagonally opposite Plastic spreaders 12 with their holes 13 to recognize. On the edge side, the mounting plate 10 is surmounted by the luminaire element 18 with its frame 21. In this case, the luminous body of the luminous element 18 at the location of the central recess 11 optionally have a formed in the form of an optical lens light-emitting surface 20. At the location of the guide / holding means 15, the mounting plate 10 windows so that cooperating with the guide / holding means 15 of the mounting plate 10 holding means 22 of the lamp element 18 respectively the frame 21 can be seen through these windows.

In the FIGS. 6 and 7 Sections are represented by mounting plate / light element configurations from different perspectives. In both cases, it can be seen that the retaining means 22 (for example pin-shaped) connected to the frame 21 of the luminous element 18 engage under the (eg hook-shaped) guide / retaining means 15 of the mounting plate 10, so that the desired locking is effected. In Fig. 7 is the z. B. formed in the form of an acrylic cuboid, connected to the frame 21 filament 19 of the lamp element 18 in addition to recognize.

• gemäß Fig. 9 wird der Leuchtenkörper 19 von einem auch in der montierten Position von außen sichtbaren Rahmen 21 umschlossen. 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.
