DETAILED DESCRIPTION OF THE DRAWINGS

[0041] FIG. 1 to FIG. 3B shows a lamp 1 for the use under water. The lamp 1 comprises a housing 2. The housing 2 consists of a first housing part 3 and a second housing part 4. In the shown embodiment, the housing 2 is formed by the connection of the two dome-shaped housing parts 3 and 4 substantially into a spherical shape. By the abutting surface 5, which is formed when the first housing part 3 and the second housing part 4 are connected with each other, there is formed a substantially spherical mechanical shell 6. Accordingly, the mechanical shell 6 has at each point of the shell 6 a double curvature, more precisely substantially the same curvature. In detail, in the represented example the mechanical shell 6 has at each point a Gaussian curvature of approximately 770 m.sup.2 (which corresponds to a diameter of the sphere of approximately 72 mm). Here, the first housing part 3 and the second housing part 4 each form a mechanical partial shell 6a, 6b of which the mechanical shell 6 is composed. In a connected state of use of the housing parts 3, 4, the mechanical shell 6 encloses a hollow space 7 in the housing 2. In this connection, the hollow space 7 is defined by the housing 2 and may be closed in a watertight manner by the connection of housing parts 3, 4.

[0042] For the connection of the housing parts 3 and 4 with each other and for the disengagement of the housing parts 3 and 4, the first housing part 3 comprises a first connecting flange 8 and the second housing part 4 comprises a second connecting flange 9. In the operating state of the lamp, the two connecting flanges 8, 9 are connected with each other. Starting from the connecting flanges 8, 9, circumferential struts 10 extend respectively along the dome-shaped contour of the housing parts 3, 4 substantially in the direction of a first vertex S1 and a second vertex S2, respectively, at which the circumferential struts 10 converge. By the circumferential arrangement of the struts 10 there are formed sections 11 which are more translucent than the struts 10. The housing 2 may be made of a translucent polycarbonate, wherein the translucence in the region of the struts 10 is lower than in the sections 11 therebetween.

[0043] Within the hollow space 7 in the area of the second housing part 4 there may be a printed circuit board 12 comprising two electrical multicolor light sources 13 (e.g. LEDs; as an alternative there can for instance also be used just one LED which is positioned in the middle; each light source may comprise one or more light emitters, such as LEDs) and a controller 47 mounted thereon, a schematically represented light sensor 14 and a schematically represented magnetic switch 15. The controller 47 is configured with computer readable instructions that when executed cause the controller to control the light color emitted by each of the electrical multicolor light sources 13 independently. The multicolor light sources 13 can be controlled to emit red and/or green and/or blue light and/or light in the ultraviolet range, i.e. having a wavelength below 400 nanometers. The controller may further be configured to flash the electrical multicolor light source at a predetermined and/or configurable interval. The light sensor 14 may be adapted to turn the multicolor light source 13 off so that the electrical multicolor light source 13 may be turned off when the light sensor 14 detects a luminous flux above a predetermined threshold value (e.g. incident sunlight at a shallow depth in the water during the day, approximately at 0-15 m below the water level). The light sensor 14 may be supplied with power from an additional accumulator 41 (plotted in dotted lines). Here, the additional accumulator 41 is only adapted to supply power to the light sensor 14 and not to the multicolor light source 13. Like the accumulators 17, the additional accumulator 41 may be charged inductively via the receiver 16.

[0044] The magnetic switch 15 may be adapted to receive a control signal via a magnetic field (e.g. by means of a Hall sensor), and it may turn on or turn off the electrical multicolor light source 13 in dependence on a control signal (e.g. direction of an approximated strong magnetic field). Within the hollow space 7 there is arranged a receiver 16 in the region of the first housing part 3 for the wireless charging of accumulators 17. In the hollow space section 19 formed between the printed circuit board 12 and the receiver 16 there are arranged accumulators 17. The accumulators 17 may each be electrically connected to the printed circuit board 12, wherein the printed circuit board 12 has electrical connections which connect the accumulators 17 to the electrical multicolor light source 13 for the power supply.

[0045] FIG. 4 shows the first housing part 3 and the second housing part 4 of the housing 2 of the lamp 1 in a state disengaged from one another. The connecting flanges 8 and 9 have a first contact surface 20 and a second contact surface 21, respectively, with the same amount of first passage 22 or second passage 23 arranged circumferentially at regular intervals for receiving mechanical connecting elements 24, e.g. screws 25 and nuts 26 (see FIG. 3A). The nuts 26 are each received and non-rotatably held in a sunk arrangement in sleeves formed at the second connecting flange 9. In the shown example, the connecting elements 24 comprise six screws 25, each with a washer and a nut 26. In some aspects, the screws may be V4A (stainless steel screws), and the screws 25 may have the nominal diameter M4. The first passage 22 and second passage 23 are arranged such that they align with each other when the first housing part 3 is connected with the second housing part 4. Furthermore, in the second contact surface 21 there may be arranged a circumferential recess 27 for accommodating a projecting annular ridge 28 (see FIG. 3B) at the first contact surface 20. As shown in FIG. 3B, the second housing part 4 has a conical guiding section 29 which engages in a corresponding receiving section 30 of the first housing part 3 when the first housing part 3 and the second housing part 4 are connected, and which will be accommodated with a press-fit when the screws 25 are tightened. In addition, an adhesion surface area 31 is provided between the contact surfaces 20, 21 for connecting the first housing part 3 and the second housing part 4.

[0046] For the mounting of the printed circuit board 12, in the second housing part 4 there may be provided supporting webs 32 with tap holes 33 arranged therein. The printed circuit board 12 may be attached at the supporting webs 32 by means of sheet metal screws 40 (see FIG. 3A) made of V4A which may be tightened or screwed down in the tap holes 33. Above the vertex S1 of the first housing part 3 there may be a fastening spigot 34 with a through hole 35 for leading through a rope for the mounting of a submergible trap (not shown).

[0047] FIGS. 5A to 5C show an arrangement of the lamp 1 in a charging station 36 for the wireless energy transfer between the receiver 16 (see FIG. 3A) and an inductive coil 37 arranged in the charging station 36. In the charging state, the connecting flange 8 of the first housing part 3 rests substantially flat on one side of the charging station 36, whereby the receiver 16 (e.g. a coil) of the first housing part 3 and the inductive coil 37 of the charging station 36 substantially lie within a horizontal plane. A receiving opening 38 is formed in the charging station 36 such that it corresponds to the dome-shaped outer contour of the second housing part 3 received therein. The charging station 36 further comprises two charging sockets 39 for the voltage supply of the inductive coils 37. In the example, the charging sockets 39 are connectors for a USB charging device. When a voltage supply is connected, the accumulators 17 arranged in the hollow space section 19 are charged through the receiver 16 via the inductive coil 37.

[0048] As shown in FIG. 5A, several lamps 1 can be arranged in a charging station 36 and may be charged respectively via an inductive coil 37. On the whole, in the shown example the charging station 36 has eight receiving openings 38 and corresponding coils 37 in order to be able to charge eight lamps 1 simultaneously.

[0049] The lamp 1 according to the second embodiment shown in FIGS. 6A and 6B is similar to the first embodiment according to FIGS. 3A and 3B, with at least two exceptions: the light sensor 14 (shown in FIG. 3B) is supplied with power from the additional accumulator 41. FIG. 6B shows a schematic sectional view of the additional accumulator 41. Moreover, the housing formed by the two exterior housing parts 3, 4 does not define a hollow space, but its interior 7 is filled with a solid filling 42. The solid filling 42 is arranged between the exterior housing parts 3, 4 and the electrical components inside the mechanical shell. The material of the filling 42 may be a thermoset (e.g. epoxy resin, phenolic resin, et cetera) or an elastomer (e.g. rubber). The material of the housing 2 may be polycarbonate or polymethyl-methacrylate. FIG. 6B identifies two points 43, 44 that may be used as injection points temporarily created in the housing for filling the housing with the filling material or as vacuum suction points for sucking-in a filling material (e.g. resin) in a liquid or viscous phase. To avoid repetition, similar elements are indicated by the same reference signs as used in the first embodiment shown in FIGS. 3A and 3B and it is referred to the above description with respect to those elements.

[0050] The lamp according to the third embodiment shown in FIGS. 7A and 7B again shares multiple elements with the previous embodiments, which therefore are indicated by the same reference signs and will not be explained again in this instance to avoid unnecessary redundancy. The housing 45 in this embodiment may be a single solid part made of polycarbonate (PC) or polymethyl-methacrylate (PMMA), which encloses inserts formed by the electrical components of the lamp 1. The housing may be injection-molded around the inserts. The inserts comprise the printed circuit board 12 comprising two electrical multicolor light sources 13, for example LEDs, mounted thereon. The multicolor light sources 13 via the printed circuit board 12 are connected to the accumulators 17, which themselves may be connected to the receiver 16 for charging. The housing 45 may be produced by supporting at least the above-mentioned inserts on guide pins 46 inside an injection mold defining the outer shape and contour of the lamp 1 and filling the injection mold with the housing material. The inserts are therefore fully embedded and fixed in the housing material. The outer shape of the housing may correspond to that of the first and second embodiments; however, the housing 45 is not hollow and the enclosed space is defined by the boundaries of the inserts.

[0051] FIGS. 8 to 10 show a lamp 401 for use under water according to a fourth embodiment. The lamp 401 comprises a housing 402. The housing 402 consists of a first housing part 403 and a second housing part 404. In the shown embodiment, the housing 402 is formed by the connection of the two dome-shaped housing parts 403 and 404 substantially into a spherical shape. By the abutting surface 405, which is formed when the first housing part 403 and the second housing part 404 are connected with each other, there is formed a substantially spherical mechanical shell. Accordingly, the mechanical shell may have at each point of the shell a double curvature, more precisely substantially the same curvature. The first housing part 403 and the second housing part 404 each form a mechanical partial shell of which the mechanical shell is composed. In a connected state of use of the housing parts 403, 404, the mechanical shell encloses a hollow space 407 in the housing 402. In this connection, the hollow space 407 may be defined by the housing 402 and can be closed in a watertight manner by the connection of the housing parts 403, 404.

[0052] For the connection of the housing parts 403 and 404 with each other and for the disengagement of the housing parts 403 and 404, the first housing part 403 comprises a first connecting flange 408 and the second housing part 404 comprises a second connecting flange 409. In the operating state of the lamp 401, the two connecting flanges 408, 409 are connected with each other. The connecting flanges 408, 409 may be adhered to each other via a glued surface 424. The horizontal arrangement of the connecting flanges 408, 409 can be fixed with a press fit 425. Starting from the connecting flanges 408, 409, circumferential struts 410 extend respectively along the dome-shaped contour of the housing parts 403, 404 substantially in the direction of a first (top) vertex and a second (bottom) vertex, respectively, at which the struts 410 converge. By the circumferential arrangement of the struts 410 there may be formed sections 411 between the struts 410. The angle 427 enclosed by neighboring struts 410 may be 60. The sections 411 are subdivided into an essentially rectangular support subsection 412 adjacent to the flange 408, 409 and an essentially triangular translucent subsection 413 adjacent to the vertices. The housing 402 may be made of a translucent polycarbonate, wherein the translucence in the region of the struts 410 and the support subsections 412 is lower than in the translucent subsections 413.

[0053] Within the hollow space 407 in the area of the second housing part 404 there may be provided a printed circuit board 412 comprising two electrical multicolor light sources 414 (e.g. LEDs; as an alternative there can for instance also be used just one LED which is positioned in the middle; each light source may comprise one or more light emitters, such as LEDs) and a controller 415 mounted thereon, a schematically represented light sensor 416 and a schematically represented magnetic switch 417. The printed circuit board 412 may be fixed to the second housing part 404 with stainless steel screws 426. The controller 415 may be configured to control the light color emitted by each of the electrical multicolor light sources 414 independently. The multicolor light sources 414 may be controlled to emit red and/or green and/or blue light and/or light in the ultraviolet range, i.e. having a wavelength below 400 nanometers. The controller 415 is further configured to flash the electrical multicolor light sources 414 at a predetermined and/or configurable interval. The multicolor light sources 414 comprise a ultraviolet light source 423.

[0054] The light sensor 416 may be adapted to turn the multicolor light source 414 off so that the electrical multicolor light source 414 can be turned off when the light sensor 416 detects a luminous flux above a predetermined threshold value (e.g. incident sunlight at a shallow depth in the water during the day, approximately at 0-15 m below the water level). The light sensor 416 may be supplied with power from an additional accumulator 418. The additional accumulator 418 is only adapted to supply power to the light sensor 416 and not to the multicolor light source 414. Like the accumulators 419, the additional accumulator 418 may be charged inductively via a wireless power receiver.

[0055] The basic functions of the lamp 401 correspond to those of the lamp 1 according to the first embodiment as described above in detail.

[0056] The lamp 1 according to FIGS. 8-10 may further comprise a wireless transceiver 420 connected with the controller 415. Specifically, the wireless transceiver 420 is a Bluetooth transceiver (e.g. Silicon Laboratories BGM111A256V2 or similar). The controller 415 may be configured to receive settings of the light color and/or a luminosity and/or a flashing interval and/or a sound file via the wireless transceiver 420. The settings may be generated in a dedicated mobile App (e.g. for the Android or iOS platform) and transmitted via Bluetooth to the one or more lamps according to the present disclosure.

[0057] The lamp 401 may further comprise a speaker 421 (e.g. PUI Audio AST-03008MR-R or similar). The controller 415 may be configured to control the audio signal emitted by the speaker 421. Specifically, the controller 415 may be configured to control the speaker 421 to play a sound file, which may be received via the wireless transceiver 420 as mentioned above. The lamp 401 may further comprise a video camera 422 and a storage medium formed by a flash storage. The controller 415 may be configured to control the video camera 422 to record images or videos and store them on the flash storage.

[0058] The control methods and routines disclosed herein may be stored as executable instructions in non-transitory memory and may be carried out by the control system including the controller in combination with various sensors and other light electrical and hardware components. The specific routines described herein may represent one or more of any number of processing strategies such as event-driven, interrupt-driven, multi-tasking, multi-threading, and the like.
