Description

The present invention relates to a recessed luminaire, in particular for force-reducing and stepless 360 ° adjustment.

Known recessed lights, in particular recessed lights for attachment to a wall or ceiling, the radiation direction of a light arranged in the recessed downlight only limited, difficult or even not set. Such known recessed lights are often rigidly mounted in the wall or ceiling and radiate only in a predetermined direction of the lamp. Other known recessed lights are designed to be pivotable in stages, so that the lamps arranged therein remain in a plurality of predetermined holding positions.

Recessed lights are also known, which are infinitely movable and adjustable by means of bearings. Such recessed lights are mounted uniaxially or biaxially rotatory. In order to release a rotational movement, these recessed lights preferably have an inner ring and an outer ring, which are connected to one another via a guide rod and corresponding recesses on the respective other inner or outer ring. So that a recessed light can move in a second rotational axis, a further ring between the outer and the inner ring is arranged, which has on the inside or outside another guide rod. This further guide rod is preferably arranged offset by 90 ° to the other guide rod. Just like the recessed luminaires with only one rotational degree of freedom, the recessed luminaires with two degrees of rotational freedom do not have the possibility of a 360 ° adjustment. To achieve this, another ring would be needed, such as an Aerotrim designed for pilot training.

The known recessed lights therefore have the disadvantage that they can either achieve no 360 ° -Justage and / or frequent adjustment of the holding position, the construction is more susceptible to interference by more parts and also priced more expensive and possibly unprofitable.

The object of the present invention is to provide a recessed luminaire which does not have the above disadvantages.

This object is achieved by a recessed luminaire according to claim 1.

The recessed light extends in the plan view preferably substantially around the central longitudinal axis (z). The preferred complete penetration of the socket with the Gelenkpfannenausnehmung distinguishes the socket of the recessed light from the socket of the anatomy, which is open only on one side.

The web 109 prevents excessive rotational movement or over-rotation of the condyle 100 in the Gelenkpfannenausnehmung 222 of the socket 200. The web 109 does not have the second radius r ₂ and blocks rotation as soon as it comes into contact with the Gelenkpfannenseitenwand 204. Inside the condyle 100 a Gelenkkopfausnehmung 122 is arranged. At a lower end of the condyle inner surface 107, a bottom part is arranged, which extends to the central longitudinal axis z and the Gelenkkopfausnehmung 122 of the condyle 100 closes towards the bottom. Centered on the bottom part 110 is arranged on this a light-emitting bulb 112, which extends into the Gelenkkopfausnehmung 122 inside.

The annular disk 160 of the inner ring 150 extends with its longitudinal extent at right angles to the central longitudinal axis z. Below the annular disc 160, a threaded wall 170 is arranged, which is integrally connected to the annular disc 160. Via the threaded wall 170, an external thread 162 (see Fig. 6 ), is the inner ring 150 with the inner surface of the joint head 107 connected. The annular disk 160 extends with its longitudinal extension on an upper side of the threaded wall 170 preferably in the direction of the central longitudinal axis z. Furthermore, the annular disc 160 extends on the upper side of the threaded wall 170 to a part removed from the central longitudinal axis z. The part of the inner ring 150 which is removed from the central longitudinal axis z lies partially on the upper condyle 102. The inner ring 150 is, exclusively of the external thread 162, formed rotationally symmetrical about the central longitudinal axis z around. The annular disk 160 of the inner ring 150 has the annular recess 152 in the center, extending around the central longitudinal axis z. On the inner ring 150 adjacent to the annular recess 152, a shoulder 154, which is formed as an undercut arranged. The shoulder 154 of the inner ring 150 is a recess on a bottom part 110 facing side of the inner ring 150th

Between the annular recess 152, the light exit means 240 is arranged. The light exit means 240 extends tapering or funnel-shaped tapered to the bulb holder 112 of the condyle 110. At a lower slender opening of the light exit means 240, a light source 250, which is held by the bulb holder 112, arranged. The light-emitting means 250 extends dome-shaped, starting from the light-emitting means 112 in the direction of an upper wide opening of the light exit means 240. At the upper wide opening of the light exit means 240 this is held in the annular recess 152 laterally from the shoulder 154 of the inner ring 150 form fit. As long as the thread wall 170, which is connected to the latter below the inner ring 150, is screwed to the condyle side wall 104 via the external thread 162, the light exit means 240 is fixed on the light bulb socket 112.

The condyle sidewall 104 has a diameter d over the condyle outer surface 105. The acetabular inner surface 207, which is substantially in abutment about the central longitudinal axis (z) in contact with the articular head surface 105, extends from the upper articular end 202 toward the lower articular end 208 (see FIG Fig. 3 ) to at least the diameter d of the condyle outer surface 105 of the condyle 100.

Fig. 3 shows the recessed light 10 according to Fig. 1 in a side view of the joint socket 200 and the condyle 100. Side of the socket 200, the two retaining springs 216 are arranged, which are connected via their respective spring units 217 with the socket 200. The retaining springs 116 extend from a lower end of the socket 200 approximately at a 40 ° angle away from the socket 200 toward an upper end of the socket 200. Centered between the two retaining springs 116 is disposed on the socket 200 one of the two pressure plates 218 , Adjacent to the lower socket end 208, the socket side wall 204 has four stop plates 219. The further stop plates 219 are not apparent from this perspective view. The stopper plates 219 are formed substantially rectangular with rounded corners and are in a thickness D (see Fig. 5a ), relative to a height H and width B of the stopper plates 219, thin-walled. On an inside ( Fig. 3 not shown), the stop plates 219 have approximately the first radius r ₁ (see Fig. 1 ) on. The stopper plates 219 are slightly inwardly extending toward the central longitudinal axis z, arched or bent, so that the stopper plates 219 extend in the direction of the lower joint cup end bent to the condyle 100. Due to the thin-walled thickness D, the stop plates 219 are designed to be elastic and allow removal of the condyle 100 downwards as soon as a corresponding force F is exerted on the condyle 100. Upon removal of the condyle 100, the stopper plates 219 are pressed outward, away from the central longitudinal axis z, and the condyle 100 can be removed. The condyle sidewall 104 has, adjacent to the lower condyle 108, the web 109 which is circumferentially formed around the central longitudinal axis z.

Fig. 4 shows the recessed light 10 according to Fig. 1 in a bottom view of the condyle 100 and the socket pan 200. The two retaining springs 216 and the two pressure plates 218 are arranged alternately at 90 ° to each other about the central longitudinal axis z around the sides of the socket 200. Furthermore, it can be seen that the spring units 217 of the retaining springs 216 are formed spirally. Next, the joint socket 200 a total of eight stop pads 219, which are arranged adjacent to the lower joint cup end 208. Each four stop plates 219 are on one side of the x-axis (see Fig. 1 ) are arranged on the joint socket 200 and the four further stop plates 219 are arranged mirror-symmetrically over the x-axis on the other side.
