- the flange 55 carries threaded holes 56 into which screws 50 inserted through the through-holes 49 can be screwed for mounting.
- Shape and dimensions of the installation niche 52 are chosen so that between the liner 51 and the housing 2 both the back and the side remains a gap.
- the front panel 21 has two mutually opposite sides of its passage opening 23 intended for the windshield 4, in the installation position shown in the example above and below the passage opening 23, in its end wall 22 and in a jacket wall 57 adjoining the end wall 22, respectively a plurality of flow passage openings 58, through which takes place a water exchange between the swimming pool 54 and the space 59, the see between the underwater headlamp 1 and the liner 51 is formed.
- the water 60 in the intermediate space 59 when the housing 2 is heated by the light emitter 5 during operation, is likewise heated, so that an upward flow can occur in the vertical section of the arrangement shown in FIG. 8, cf. the arrows 61.
- FIG. 7 schematically shows, with reference to a preferred exemplary embodiment, a security system 62 according to the invention for monitoring the underwater area in a swimming pool 54.
- this comprises two underwater floodlights 1, which are underwater headlights 1 according to the invention.
- Each underwater spotlight 1 is connected by means of only one connecting line 33 to a central operating device 63, which in the example is a computer.
- each of the cameras 8 is connected to the operating device 63 by means of an Ethernet connecting cable leading through the connecting line 33 (not shown separately in the figures), so that the power supply of the camera 8 and the data exchange with the operating device 63 are common by means of the Ethernet connection cable (ie without additional cables).
- the power supply of the light emitter 5 is carried by extending in the connecting cable 33 cable.
- the operating device 63 has image evaluation means, in particular suitable software, which is adapted to a recognition of predetermined contours, in particular to the contour of a human body.
- FIGS. 9, 9a and 9b show a lens disk 11 known per se with supports 13 formed thereon, the lenses 12, in conjunction with a reefing of the lens disk, being adapted to an elliptical light exit distribution.
- the ellipse main axis runs parallel to the ribs of the corrugation.
- these lens disks in the light emitters 5 are selected on the longitudinal center line 14 by way of example.
- FIGS 10, 10a and 10b show slightly different lens discs 11. Each lens provides a rotationally symmetric light emission. These lens disks 11 were selected in the example in the light emitters 5 on the longitudinal line 15.
- FIGS. 11, IIa and IIb show a further variant of the lens disks 11. These likewise provide rotationally symmetrical light emission with their lenses. These lens disks were selected in the light emitters 5 on the longitudinal line 17.
- an underwater headlamp 1 according to the invention is presented according to a second preferred embodiment.
- like reference numerals are used for corresponding elements or features (as in the following third exemplary embodiment).
- the difference from the exemplary embodiment described with reference to FIGS. 1 to 6 is that in the variant according to FIGS. 12 and 13, the shape 18 of the front screen 4 has a different shape. While the formation 18 here also has a greater extent in a longitudinal direction L than in a transverse direction Q perpendicular to the optical axis 9 of the camera 8, here the central slice area 25 through which the optical axis 9 or whose extension meets, with a substantially rectangular bounded, flat flattening 64 formed. Their extension is perpendicular to the optical axis 9.
- the longitudinal dimension of the flat 64 is denoted by a and the transverse dimension b.
- the central one The disk portion 25 of the molding 18 extending within the circumferential transition portion 19 is concave on its outside in a sectional plane parallel to the longitudinal direction L through the optical axis 9 when viewed in the longitudinal direction L in the longitudinal center portion a and concaved on both sides thereof ,
- the central disk region 25 is flat on the outside when viewed in the transverse direction Q in the transverse center section b and concavely rounded on both sides thereof.
- the convex formation 18 is rotationally symmetrical with respect to a geometric rotation center axis.
- the rotational center line coincides geometrically with the optical axis 9 of the camera 8.
- the shape of the molding 18 is approximated in the area surrounded by the transition region 19 disc portion 25 of a spherical cap. Outside the transition region 19, the front pane 4 made of transparent safety glass extends to its outer edge 27.
- the light emitters 5 in this example are located outside the molding 18 behind the planar disk region 26 of the windshield 4. All of the disclosed features are essential to the invention.
