Swiveling recessed luminaire

The invention relates to a swiveling built-in lamp with a stationary mounting ring and a mounting ring opposite this lamp holder pivoted on all sides.

The usual built-in lights with a lamp holder that can be swiveled in all directions consist of one that is open at the bottom spherical housing that lies on a mounting ring and remains aligned in every possible pivot position. The manufacture of the ball housing, which usually takes place in the metal spinning process, is complex. As a result, the known recessed spherical lights are also relatively expensive.

Based on this prior art, the invention is based on the object of providing a recessed luminaire of the known type to improve so that they are made of inexpensive manufacturable, possibly made of plastic injection molded individual parts can be put together.

This object is achieved according to the invention in that the lamp socket is gimbaled in one first carrier, which is pivotable about a first pivot axis

is bar and in a second, pivotable about a stationary, perpendicular to the first pivot axis second carrier.

The provision of a cardanic suspension for the lamp socket enables a particularly simple and inexpensive design the built-in lamp according to the invention. The two supports, which can be moved about mutually perpendicular axes, can be inserted into the Forms that are cheapest for low-cost production and are produced using the most cost-effective methods, for example as a plastic injection-molded body or as simple stamped parts made of metal. It is through appropriate training the bearing points of the two carriers possible, the frictional forces between the different bearing parts completely to be chosen according to the requirements. In the construction according to the invention, it is just as possible that To make recessed lights particularly easy to swivel or - if this makes sense according to the desired application appears - stiff.

According to the invention it is also proposed that the second Pivot axis penetrates the mounting ring. Such a design allows the mounting ring to be used as a bearing point.

It has also proven to be useful that the first carrier is an annular body concentric to the mounting ring. One Such a configuration is expedient because it ensures that the built-in lamp is in all possible pivoting positions offers a harmonious view from below.

In a preferred embodiment, the second carrier is designed as a basket with four arms, two of which are opposite arms articulated with the mounting ring and two further arms, which are offset by 90 ° with respect to the first arms, are articulated to the first carrier. The training of the second carrier as a basket with different arms is

especially suitable for production. It also allows first-class heat dissipation from the recessed spotlight to the one above Surroundings. This is particularly important for recessed spotlights using halogen or high-pressure quartz lamps.

In a particularly advantageous manner, the pivot axes are formed by pins molded onto the first and / or the second carrier and recesses corresponding to this are formed in the counterparts. The one-piece molding of the pins and bearings promotes the solution to the task of creating a particularly inexpensive recessed luminaire.

Finally, it is also proposed according to the invention that at least some, electrically non-conductive parts of the built-in spotlight are designed as plastic injection molded parts.

Below is a preferred embodiment of the invention described in detail with reference to the drawing.

The recessed luminaire shown is fixed in a ceiling or wall 2 with an installation ring 1, which is only shown schematically. The mounting ring 1 has two diametrically opposed bearing bores 3 and 4 in the matching bearing journals 5 and 6 engage a basket-like so-called second carrier. The basket-like second carrier is about the axis a pivotable and, in addition to its two arms 7a and 7b carrying the trunnions 5 and 6, has two further arms 7c and 7d, which are arranged in a plane which is perpendicular to the plane determined by the pivot axis a. The arms 7c and 7d carry at their lower ends at the level of the pivot axis a running bearing bores 8 and 9, which the bearing points for two journals 10 and 11 form. The bearing journals 10 and 11 are integrally formed on a first, circular ring-shaped one Carrier, - which is designated as a whole by 12. The pivot axis a forms in the alignment according to Figure 1 a common plane with the pivot axis b, which through the bearing pin 10 and of the first carrier and the corresponding bearing bores 8 and 9 is formed.

The first carrier 12 has in its center a hub-like body 14, which via radially extending spokes 15 with the circular cylindrical outer area is connected. The hub-like central body is used to accommodate the lamp socket 16, which is screwed to the first carrier with the aid of a metal tab 17 and a fastening screw 18. At 19 and 20 are electrical supply lines. The recessed luminaire shown is equipped with a small Kalogen bulb 21. A The reflector 22 is also attached to the first carrier 12. Below the reflector 22 is a diffuser 23 in a circumferential groove 24 of the first carrier used. The lamps-
