The lantern 20 is substantially cylindrical with a substantially disc-shaped upper part 21 , a substantially cup-shaped lower part 22 , a substantially cup-shaped bottom 23 , a substantially disc-shaped insert 24 , a substantially disc-shaped lid 25 and a housing body 26 as a middle part. The housing body 26 is surrounded by a sleeve-shaped translucent cover 27 ,

lower part 22 and soil 23 are connected by a bayonet ring 28 with inserted seal 29 , The lid 25 is on top of the shell 21 screwed on with an intermediate sealing washer 30 (or sealing mat).

Screwed together are also the top 21 and the lower part 22 , For this purpose, an axially directed, continuous screw is at a central location 31 intended. This extends through an axially directed bore 32 in the housing body 26 through, as well through a hole 33 in use 24 , By tightening the screw 31 also becomes the translucent cover 27 between the lower part 22 and the top 21 held and fixed in corresponding peripherally circumferential recesses.

The housing body 26 is essentially solid or semi-solid and made of aluminum or other good heat conducting material. Also, the other components mentioned can be formed correspondingly good thermal conductivity.

As light sources are a white LED 34 , a red LED 35 and a green LED 36 intended. The LEDs 34 . 35 . 36 sit on associated boards 37 . 38 . 39 ,

The housing body 26 has a cross-section that is substantially in the shape of an equilateral triangle. Accordingly, the housing body 26 outside three mutually angled contact surfaces 40 . 41 . 42 on.

The contact surfaces 40 . 41 . 42 each have a recess 43 . 44 . 45 on, in each case the associated board 37 . 38 . 39 is arranged. Preferably, the boards are 37 . 38 . 39 shed.

The recesses 43 . 44 . 45 indicate the outer shape of the boards 37 . 38 . 39 matched lateral edges, so that there is a clear positioning of the boards in the recesses.

That from the LEDs 34 . 35 . 36 radiated light is focused by a respective upstream lens 46 . 47 . 48 , The lenses are located on the outside of the contact surfaces 40 . 41 . 42 on, have a substantially part-cylindrical outer shape and are provided with projections 49 . 50 provided on the corresponding lateral edges of the recess 43 . 44 . 45 abut and so clearly define the position of the respective lens.

In addition, each lens can have an extension 51 each located next to the corresponding recess 43 . 44 . 45 into the interior of the case body 26 extends and carries a part of the radiated light. Inside the case body 26 can for each extension 51 a separate light sensor can be provided, with which the emitted light intensity can be detected over time. With the help of an electronic circuit, not shown, then the electrical power of the LEDs can be readjusted individually to achieve a constant light intensity.

In each case between the individual contact surfaces 40 . 41 . 42 has the housing body 26 one each axially directed slot 52 . 53 . 54 on. The slots are provided for receiving apertures 55 . 56 . 57 ,

Every aperture 55 . 56 . 57 has a substantially T-shaped cross-section, with a central plug-in web 58 and two side deck bars 59 . 60 , Each plug-in 58 is for inclusion through the associated slot 52 . 53 . 54 provided and has corresponding dimensions. The deck bridges 59 . 60 the aperture 56 cover lateral areas of the lenses 47 . 48 for the port and starboard LEDs 35 . 36 , As a result, the beam angle in the main direction of the ship is exactly limited. Analog act the lateral deck webs 59 . 60 the side panels 55 . 57 in part as apertures for the lenses 47 . 48 and on the other hand as apertures for the lens 46 the white LED 34 , which has the function of a tail light.

The deck bridges 59 . 60 go into each other and are curved corresponding to or similar to the curvature of the translucent cover 27 , This allows the light of the LEDs through while protecting lenses, screens, LEDs and electronic components from external influences.

The housing body 26 sits on the insert 24 , The latter has holes 61 for the passage of electrical lines, via which the LEDs are supplied with power. The electrical wires are not shown and run from the back of the boards 37 . 38 . 39 through corresponding cavities in the housing body 26 and through the mentioned holes 61 up to one in 4 invisible back of the insert 24 , There is a circuit board 62 cast with appropriate electronic components to power the LEDs.

Other electronic components can also be in the ground 23 be arranged. This has an obliquely downward bore 63 for the passage of an electrical line.

To establish a precise relative position of use 24 to housing body 26 indicates the use 24 at its top 64 slots 65 . 66 . 67 on that with the jetties 58 . 59 . 60 correspond. These can be combined with protrusions 68 . 69 in the lower part 22 interact and so the position of the insert 24 in the lower part 22 establish.

Instead of the lid 25 can on the shell 21 be arranged another position lantern, such as a Toplicht, anchor light or all-round light. In the present case is a white signal lantern 70 (All-round light) provided. Their structure will be described below with reference to 6 to 11 explained.

The signal lantern 70 has a pedestal 71 , a dome-shaped base housing 72 , a sleeve-shaped translucent cover 73 and a lid 74 on.

On the pedestal 71 and protected by the overlying base housing 72 is a circuit board 75 with a white LED 76 held. A top 77 of the pedestal 71 is with a mount 78 provided, the inner edge of which has projections and recesses and with corresponding projections and recesses on the board 75 corresponds and so a unique position of the board 75 on the pedestal 71 guaranteed. The mount 78 corresponds in its contour to the recesses 43 . 44 . 45 , The board 75 can therefore with regard to the external shape with the boards 37 . 38 . 39 to match.

The base housing 72 is on the pedestal 71 held by axially directed screws or connected thereto. In addition, the socket housing has 72 an axially directed, central bore 79 for receiving or for the passage of a cylindrical lens 80 on. This extends from the LED 76 to the lid 74 and is at an upper end with a funnel-shaped recess 81 provided, which has an inner circumferential wall 82 having. The latter also forms a reflection surface of the lens 80 ,

At one of the deepening 81 opposite end of the lens 80 So in the field of LED 76 , points the lens 80 a cylindrical recess 83 on, which with a convex light entry surface 84 concludes. The LED 76 dives into the depression 83 and has only a small distance to the light entry surface 84 on.

The depression 83 is bounded by a peripheral edge 85 , The latter sweeps parts of the board 75 and thus defines the relative position of the LED 76 to the lens 80 , Corresponding to the predominantly massive, cylindrical shape of the lens 80 , This has a circumferential cylindrical wall 86 as a light exit surface. In the area of the cylindrical recess 83 points the lens 80 a conical outer shape so that the peripheral edge 85 a much smaller diameter than the surrounding wall 86 ,

The Lens 80 points in the area of the transition between the encircling wall 86 and the subsequent conical area below the same a circumferential collar 87 on. This is inside the base housing 72 so that only about 2/3 of the axial length of the circumferential wall 86 over the base housing 72 towards the lid 74 protrude.

That from the LED 76 radiated light passes through the convex light entry surface 84 in the massive lens 80 inside, it's on the wall 82 re inflects and steps over the encircling wall 86 from and in fact substantially perpendicular to the main emission of the LED 76 , Subsequently, the light only passes through the translucent cover 73 and (previously) the space between the latter and the lens 80 ,

The lid 74 is with a circumferential walkway 88 provided, which is axially directed and on the circumferential wall 86 , namely in the area of the transition to the funnel-shaped wall 82 , is present. For this purpose, the circumferential bridge 88 a slightly wider outer diameter than the circumferential wall 86 and is provided with an inwardly directed heel, so that the circumferential wall 86 in this area is secured against transverse axial movements. Also, the contact allows for heat dissipation from the lens 80 in the lid 74 into it.

lens 80 and / or translucent cover 73 are by gluing with the lid 74 on the one hand and the base housing 72 on the other hand.

At a bottom of the base 71 is arranged a board with the required electronic circuits. The power supply is via lines 90 coming from the board 89 led in the direction of the underlying 3-color lantern. top 21 , Housing body 26 and use 24 have the additional cable bushings required for this purpose.

Since the signal lantern 70 instead of the lid 25 is provided has the base housing 72 Bushings for screws analogous to the attachment of the cover 25 on.

The sealing washer 30 according to 10 is also in 4 shown, consists of rubber and acts insulating, here (see in particular 7 ) between the pedestal 71 and in 4 marked upper part 21 ,

The 12 to 16 show a position lantern as a combination of the above-described 3-color lantern 20 and the signal lantern 70 , Despite the highly integrated design, the combination is simple in design and in electrical function. By simple modification, namely by replacing the signal lantern 70 against the lid 25 On the basis of the same construction, the described combination of 3-color lantern and signal lantern or only the 3-color lantern can optionally be produced.

Easy access to the electrical connections is possible thanks to the bayonet ring already mentioned above 28 that allows it, lower part 22 and soil 23 separate from each other.
