Description

FIELD OF THE INVENTION The present invention relates to the sector glow used in the control of waterborne traffic.

BACKGROUND OF THE INVENTION

Today, especially in the control of waterborne traffic, sector glories based on incandescent light sources such as incandescent bulbs and other similar light sources are used. In addition to the high power requirement and the relatively short life span, the problem of sector fluorescent lamps based on incandescent bulbs and other similar light sources is that problems with current incandescent sector fluorescents are usually mechanical arrangements of sector plates which are usually not included in the actual in practice, the entire splendor is installed inside the splendid building. The installation and adjustment of sector glasses is a fine mechanical job. It is also expensive to build and maintain a luxury building.

In addition, for the sector gloss to work and to be reliable, the 25 uncertainty ranges should be kept to a minimum, so that at different distances from the sector gloss, the boundaries between sectors are also accurate and positioning, etc., using sector glosses »t using safe and reliable

§ 30 In addition, one of the worst deficiencies of sector fluorescence based on glowing light sources is the reduction in luminous intensity of colored sectors. O x In the traditional solution, colored light areas are formed by 'filtering white light using colored glass plates o as filters. The use of filters reduces the luminous intensity of red and green 35 to typically as low as 25% compared to δ from white luminous intensity.

C \ J

2 When using conventional solutions based on incandescent light sources, the problem is also the large size of the lights and the need for maintenance, as conventional light sources require space and need to be serviced, i.e. having to replace bulbs or the like 5 relatively often.

Known methods of using LED technology in sector fluorescence are based on the fact that a plurality of low power LED light sources are placed in a circle so that the optical axis of the LED light sources is parallel to 10 horizontal planes. LED light sources are usually placed inside the drum lens, which allows the vertical angle of the light to be reduced. Sectors are created by placing differently colored LED light sources on the same periphery and installing opaque inserts between the different colored LED areas, which are oriented in the direction of the beam emanating from the center of the sector flux. This method also has several limitations and problems. Already at the manufacturing stage, it is necessary to install different colored LEDs on the circuit board, so such sector illuminations are unique in their light sources. In order to achieve even reasonable areas of uncertainty between the different color sectors, it is necessary to install baffles both inside and outside the drum lens of the lighting device, and external baffles with supporting structures must be individually constructed for each sector glow. Depending on the number of LED light sources, the minimum angle of a single color sector is typically greater than 20 degrees 25 to achieve sufficient luminous intensity and sufficient luminance uniformity within that color sector. The sector boundary inaccuracy is typically of the order of 1 degree or more, and in addition, the luminous intensity of the color range is typically reduced when approaching the sector boundary, δ

towards x is one or more LED light sources, the light of which is refracted by the lens or mirror, at least predominantly horizontally. o The sector glow of FI20041703 is built vertically with each o 35 color on its own layer. For each layer (color), the number o of widths of sectors is freely selectable, so that by moving the sector plates mounted around the LED light sources, which prevent light transmission, the desired sector width and position is obtained.

3

The number of sector disks is freely selectable. The sector plates are movable and the sector plates can also be adjusted in the field.

The well-known LED sector technology can also be used to produce factory-ready and measured sector fluorescence at the factory. All sectors are preset, but to get the sectors in the right direction, the sector glow must be rotated in the right direction at the installation site.

After installing the sector flux, the owner (eg, 10 Maritime Authorities) performs a sector check.

The sector check is performed at night by driving the ship in the fairway in the direction of the sector where the sector colors change. Usually, driving starts from a distance and is driven obliquely towards the sector glow so that the sector boundary is exceeded. After the visual inspection by the sector inspector indicates that color 15 has changed, the position is saved and reversed and tilted back across the sector boundary. This is usually done by industry standard four times at four different distances from the glow. Typically, it is necessary to check all sector boundaries. There can be up to 9 to 10 sector boundaries in one sector list.

20

Therefore, the revision of sector boundaries is laborious and expensive. In prior art solutions, it is always necessary to perform the lithographic printing if the sector luminaire has to be removed from its attachments, for example for the repair of light sources or for replacement of light sources. Also, solutions based on state-of-the-art LED light sources do not allow one or only a few types of light sources to be used in different sector fluorescents, which would not be easy to store because each prior art sector flux is customized only to its location.

σ> o o g 35 Detailed Description of the Invention δ c \ j

As shown in Figure 1, the sector flux comprises a light source unit 100 and a blackout wall unit 110. The structure of the light source unit 100 and 6 blackout wall unit 110 has at least one layer for each color, and each light source unit layer 101 has 101 An LED light source and, for example, a high power LED of at least 1 Watt. The light of the light source 101, 102, 103 is refracted by the lens 104, 105, 106 at least substantially horizontally. The function of the sector fluorescence of the invention is thus based on the shape of the light visible through the lens or through the reflector. When viewed through the lens, the light source has a vertical and narrow ίο shape. The narrower the light source, the more accurate the sector boundary. The light source unit 100 has a light impermeable plane 107, 108, 109 between and / or below the various layers.

The sector fluorescent screen wall unit 110 has, at each height corresponding to the layer of the light source unit, at least one light transmitting light through which a portion of the horizontal light is passed to leave the desired sector or sectors, i.e., the light apertures from each layer of light source. The location and number of light apertures in the sector illumination 20 eclipse wall unit determines where the light sources of each layer are displayed. The location and number of light apertures can be selected, for example, in the manufacture of a blackout wall. The blackout wall unit has a fastening portion, e.g., a mounting foot 120, by means of which the blackout wall unit, and thus the entire sector glow, can be attached to the mounting base 130.

The light source portion of the sector fluorescence shown in Figure 1 has three layers, corresponding to the heights of the light aperture 111, 112 in the darkening wall, from which the light of the light source 101, 102, 103 g 30 of that layer is visible. The light aperture of the blackout unit at the lowest layer height g is not shown in Figure 1. The light apertures 111, 112 at different x heights show different colors, e.g.

such that white is visible from the upper light aperture 112, green o from the white light aperture 111, and red o from the lower light aperture 111 (not shown in Figure 1). However, colors other than green, red and white can be used. The light apertures 111, 112 are conventionally arranged so that they are exactly overlapping, but they can also be arranged such that there is a certain distance 7 between the apertures 111, 112. The openings 111, 112 may also be more than one per layer.

The light source unit 100 can be mounted and secured in the middle of the 5 screen wall unit 110 so that the layers of the light source unit and the light apertures of the screen wall unit are aligned. The attachment of the light source unit 100 to the blackout wall unit 110 may be accomplished by means of fastening, such as screws or other similar detachable fastening means. When the light source unit io is mounted in the center of the screen wall unit, the horizontal distance of the light sources of the light source unit from the screen wall 116 of the screen wall unit is typically the same around the sector glow. The distance of the screening wall 116 from the light sources may also vary according to the accuracy requirement of the sector. Additional optics may be employed in the sector luminosity at the islet apertures 111, 112 in the screening wall 116, whereby the vertical light distribution of the light sector emitted by each aperture can be reduced or widened as necessary.

The sector glow screen wall unit 110 also comprises support members 117, 118 to which the screen wall 116 can be attached.

The structure formed by the support members 117, 118 and the blackout wall 116 is substantially rigid. The support components 117, 118 of the screen wall unit 110 may also serve as a side support and / or vertical support for the light source unit 100 installed inside the screen wall unit 110.

In one embodiment of the invention, the lower part of the light source unit has a space 119 in which the electronics used, for example, to control the light sources g 30, can be placed. The connectors for the power supply co of the light source section may also be located in the space 119.

Figure 2 illustrates how the light source unit 100 is removable o from the screen wall unit 110. Although the light source unit 100 is detached o g 35 from the screen wall unit 110, it is not necessary to o remove the screen wall unit 110 from its mounting surface. When the light source unit 100 is reinstalled, it can be mounted around its own vertical axis in any position inside the blackout wall unit 110 because the light sources 8 are horizontally omnidirectional and because the blackout wall unit 110 mounted on the mounting base defines a light sector entering different sectors. Therefore, when the screen wall unit 110 is attached to its substrate, after changing the light source unit 100, there is no need to perform sector alignment check measurement since the light apertures of the screen wall unit 110 defining light sectors are in the same position as before the light source unit is replaced.

Fig. 3 shows a light source unit 100 according to an embodiment of the invention. The light source unit consists of three overlapping light source portions 301, 302, 303. The lower part of the light source portions 301, 302, 303 has a light impermeable plane 107, 108, 109.

In one embodiment of the invention, a light source having a radiation beam symmetrical with respect to the optical axis of the light source section 301, 302, 303 is mounted in the sector luminosity such that its optical axis is vertically oriented, i.e. straight up or straight down.

In one embodiment of the invention, the plane 107, 108, 109 at the bottom of the light source portions 301, 302, 303 comprises a base plate on which the sector fluorescent light sources, e.g., LED light sources, are mounted. The washer may be, for example, a circuit board. The circuit board can be mounted on a heat sink. Often, aluminum or ceramic material is used as the board material to provide good thermal conductivity, but it is also possible to use a conventional fiberglass board. The light sources can also be mounted directly

Tt to the heat sink surface, δ

(M

g 30 The light source emitting in the main vertical direction is individually mounted or integrated with an optical lens 104, 105, 106 o x or a conical mirror which rotates the light horizontally. The light is thus * characterized in that it is visible through the lens 104, 105, 106 or the mirror as vertical and narrow linear light. The beam width towards the viewer o g 35 depends on the optics and is typically less than 2 mm. The narrower the beam, the better.

In the solution according to the invention, several LEDs of the same color can be superimposed in layers, thus increasing the light range.

5 A shield 320 is provided adjacent the light source unit, for example, around the light source unit, which protects the light source unit from external stress. The shield 320 surrounding the light source unit at its sides may be cylindrical and its material used is a substantially transparent material, for example polycarbonate. The shielding of the light source unit with the top and bottom structure of the light source unit may provide a substantially dense space.

The amount of light emitted by each color layer can be optically controlled by the electronics used to control the light sources, and if a decrease in light output of one single color layer is detected over the other color layers, the control automation can turn off the LEDs on all layers or alternatively adjust the

20

The electronics used to control the light sources can also control the possible blinking of the light sources and the light output of the light sources.

Light source electronics can also be used to change the light source settings by programming the desired settings in the electronics 25, such as the light output of the light sources and the blinking of the light sources.

For example, the desired settings can be programmed into the electronics whenever the light source unit is used in a new sector lighting.

In one embodiment of the invention, the light source unit, e.g., on its upper surface, may have means to facilitate lifting of the light source unit from within the screen wall unit. The means for facilitating lifting may be, for example, a handle.

Figure 4 shows a sector fluorescent screen unit 110 according to the invention, inside which the light source unit has been removed. The screen wall unit 110 comprises light apertures 112, 113, 114 from which light is reflected in desired sectors. The location and size of the light apertures 112, 113, πο 114 affect the sector areas. The support members 117, 118 of the blackout wall unit are also shown in Figure 4.

The screen wall unit 110 also comprises a mounting and support means for the light source unit, by means of which the light source unit can be removably attached to the screen wall unit 110.

Is, for example, acid-proof steel can be used as the material for the screening unit. The screen wall unit 110 and / or the light source unit may comprise connectors for supplying power to the light source unit. The upper part of the structure formed by the screen wall unit 110 and / or the screen wall unit 110 and the mounted light source unit 20 is sealed, thereby protecting the sector from water and snow, preventing them from entering the sector glow from the top.

The lower part of the screening unit 110 may be open to prevent any ingress of water or snow within the sector glow.

The light apertures of the screen wall unit or around the screen wall unit 25 may have shields, e.g., glass or plastic surfaces, but the light apertures may not need shields, especially to maximize the amount of light emitted from the openings. If a protective structure is used in the light apertures of the screen wall unit or around the screen wall unit, the lower part of the screen wall unit may also form § 30 with the light source unit attached to it,
