DETAILED DESCRIPTION

(7) In the following, identical or functionally identical components in an exemplary embodiment are identified by the same reference symbols. For the sake of clarity, not all parts that are the same or functionally the same in the individual figures are provided with a reference number.

(8) The exploded view according to FIG. 1 shows a built-in light and/or camera 1 which is configured to be inserted into a receiving opening 4 of a wall 5. The wall 5 can be an inner wall of a machine (not shown), which encloses a process chamber in which the machining of workpieces can take place, at least in some areas. Such walls 5 can be formed from a planar material with a wall thickness t, wherein the material is typically a metallic material. The wall 5 has a first side and a second side opposite the first side, the first side of the wall 5 facing the process chamber.

(9) The receiving opening 4 can be designed in the shape of a cuboid, and the edges can be rounded. The installation opening 4 has a width B3 and a length L2.

(10) For the sake of simplicity, the built-in light and/or camera 1 is first described in the configuration as a pure built-in light 1 and also designated as such.

(11) The built-in light 1 comprises a housing 10 with a front side area 11 and a rear side area 13, wherein the rear side area 13 is able to protrude through the installation opening 4. The rear side area 13 has a rear side 14 and the front side area 11 has a front side 12, wherein the front side 12 is arranged on the first side of the wall 5 and the rear side 14 on the opposite second side of the wall 5 when the built-in light 1 according to FIG. 3 is in the inserted state.

(12) The housing 10 is preferably cuboid and, as shown, can have four side walls 15, 16, 17, 18, the housing 10 having a width B1, a length L1 and a height H1. On the front side area 11, the housing 10 has a preferably circumferential flange 22, which protrudes from the side walls 15, 16, 17, 18 and forms a stop 20. As can be seen from FIG. 4, the built-in light 1 has a width B2 and a length L2 measured with the stop 20 in the front side area 11, the width B2 being greater than the width B1 and the length L2 being greater than the length L1. The stop 20 specifies how far the housing 10 can penetrate through the installation opening 4 into the wall 5.

(13) One or more light sources 40 can be arranged in the housing 10, wherein the light sources 40 are preferably LED light sources, which are arranged on one or more plates, preferably in a grid. In addition, the housing 10 has a housing opening 42 in the front side area, through which the light emitted by the light source 40 can be emitted. The housing opening 42 can be closed by a plate 45 in the front side area 11, the plate 45 preferably being a transparent plate 45.

(14) In order to fasten the built-in light 1 or the built-in light and/or camera 1 in the installation opening 4, several fastenings 50 are provided, which protrude from the side walls 16, 18. In a preferred embodiment, at least one fastening 50 is arranged on opposite side walls 15, 16, 17, 18, that is to say on side walls 16, 18 and/or on side walls 15 and 17.

(15) The fastenings 50 are inserted into a cut-out 60 in the relevant side wall 15, 16, 17, 18, and protrude from the cut-out 60 over the relevant side wall 15, 16, 17, 18.

(16) The cut-out 60 can be incorporated or molded into the side wall 15, 16, 17, 18 of the housing 10 as a semicircular groove, for example by means of a fillet milling or a plate milling, and can continue to run out in a longitudinal direction. The semicircular groove has a diameter D2, wherein the depth of the semicircular groove is preferably greater than ½ D2 and less than D2.

(17) Undercuts 65, which preferably face the front side area 11 and/or the rear side area 14, can be formed in the cut-out 60. Each undercut 65 can—as can be seen from FIGS. 2-4—be formed by a recess 66, which is incorporated or molded into the housing 10 from the rear side area or the rear side 13 and connects the rear side 13 to the cut-out 60.

(18) The fastening 50 protrudes from the cut-out 60 and, adjacent to the cut-out 60, projects beyond the relevant side wall 15, 16, 17, 18 in a V or U shape with two flanks which meet in a dome. By means of two flanks, the fastening 50 can make an elastic evasive movement in the manner of a door latch when the built-in light and/or camera 1 is inserted. In this case, the fastening 50 is pressed elastically in the direction of the relevant side wall 15, 16, 17, 18 via a first flank. As soon as the dome has passed the installation opening 4 of the wall, the fastening 50 springs back and presses the wall 5 with the second flank into a spring-loaded form fit, whereby the wall 5 is clamped between the stop 20 and the fastening 50. The built-in light and/or camera can be pulled into the wall 5 via the fastening 50 and is automatically centered in relation to the installation opening 6. The dome protrudes at a distance from the relevant side wall 15, 16, 17, 18 and the width B1 or the length L1 and twice the distance of the dome is greater than a width or length of the installation opening 6. However, the width B1 or the length L1 and twice the distance between the dome and the relevant side wall 15, 16, 17, 18 are smaller than the width B2 and the length L2. The dome preferably protrudes approximately 3 mm to 10 mm, preferably approximately 5 mm, from that of the relevant side wall 15, 16, 17, 18.

(19) As shown in FIGS. 1-5, the fastening 50 can have two leg spring sections 52 and a bracket section 58. The two leg spring sections 52 are arranged at a distance from one another and are connected to one another via the bracket section 58. The bracket section 58 is oriented substantially in the longitudinal direction.

(20) The leg spring section 52 has a first leg 53 and a second leg 54, wherein it is possible for a helical spring section having a winding direction W to be arranged between the first leg 53 and the second leg 54. The first leg 53 forms a free end, whilst the second leg 54 is connected to the bracket section 58.

(21) The helical spring section of the leg spring section 52 has a diameter D1, the diameter D1 roughly corresponding to the diameter D2 of the semicircular groove or cut-out 60.

(22) The first leg 53 protrudes from the helical spring section and engages in the undercut 65 in the cut-out 60, as shown in FIGS. 2 and 3.

(23) The second leg 54 is V-shaped and forms the first flank, the second flank and the dome of the fastening 50. The second leg 54 protrudes inclined from the cut-out 60 and projects beyond the relevant side wall 15, 16, 17, 18 in such a way that the dome is arranged in the direction of the front side area 11 beyond the cut-out 60. The bracket section 58 is pressed by the elastic spring force in the winding direction W against the relevant side wall 15, 16, 17, 18.

(24) The bracket section 58 is arranged at an angle to the second leg 54 and rests on the relevant side wall 15, 16, 17, 18. In addition, the bracket section 58 can rest against the stop 20 or the flange 22, wherein a recess 23 adapted to the bracket section 58 is preferably incorporated or molded into the flange 22 and accommodates the bracket section 58. The bracket section 58 can be pressed against the stop 20 by the spring force of the fastening 50.

(25) Due to the form fit of the first leg 53 in the undercut 65 and/or the form fit of the bracket section 58 in the recess 23, the fastening 50 can be clipped into the cut-out 60 and is held there in a loss-proof manner.

(26) With reference to FIG. 4, it can be seen that the built-in light 1 and/or camera has an electrical connection 80, wherein the electrical connection is arranged on a surface 85 inclined by 45° to the rear side 14 on an edge between two side walls 15, 16, 17, 18. The electrical connection 80 is rotatably arranged on the inclined surface 85, wherein the electrical connection 80 is preferably rotatable through 180° on the inclined surface 85.

(27) The electrical connection can be single-pole or multi-pole and serves, on the one hand, to supply current to the built-in light and/or camera 1 and/or to exchange data.

(28) As can be seen from the further development according to FIG. 5, a camera 30 which is inserted into the housing opening 42 can also be provided. The camera 30 can—as shown in FIG. 5—be arranged in the housing opening 42 in such a way that the camera 30 is surrounded by light sources 40 in the front side area. This configuration corresponds to a combination of a built-in light and camera 1, wherein the fastening 50 is not shown in this illustration. Alternatively, in a further development, not shown, the housing 10 can accommodate at least one camera 30 and have no light sources 40, wherein this configuration corresponds to a built-in camera 1.
