RU215620U1 - Light-optical device of navigational aids - Google Patents

Abstract

The utility model relates to special lighting equipment and is designed to ensure the navigational safety of navigation in the coastal sea zone, on approaches to ports and on inland waterways.

The light-optical device of beacon navigation aids consists of a special lens, an LED matrix (light source), a heat-removing element (radiator), a control unit, a protective cap and a base.

The LED matrix is mounted on a heat sink for heat dissipation, the lens is located on the matrix. The light flux, passing through the lens in the center, is reflected by 90 degrees, thereby ensuring the spread of light by 360 degrees. The control unit of the product allows you to set standard characteristics for each aid to navigation equipment.

Thanks to this design of the device, the efficiency of using the light source is increased, its weight is reduced, the design is simplified, the thermal regime is improved, reliability is increased and, as a result, the cost of mass production is low.

Description

The utility model relates to special lighting navigation equipment for lighthouses, navigation signs and floating navigation equipment both for the sea and for inland waterways, and is designed to ensure navigational safety in the coastal sea zone, on approaches to ports and on inland waterways.

Known designs of light-optical products designed for such purposes, which use several LED light sources (LEDs, LED matrices), lenses, reflectors. The disadvantages of such designs include increased energy consumption due to the presence of more than one light source, which requires an increase in costs to ensure the continuity of power supply, the complexity of the design and the increase in weight and size characteristics of the product in comparison with the claimed light-optical device, where one LED light source is used.

Products where several LED sources are used consist of sector LED light sources, each source directs light only to the corresponding sectors in the horizontal plane, and this is a significant drawback in the use of such light sources to ensure navigational safety of navigation. To provide navigation light in a 360-degree sector, several dozens of LEDs or matrices must be used.

These disadvantages can be minimized or significantly reduced by using a lens design that has not previously been used in navigation equipment. The technical result of the claimed product consists in increasing the efficiency of using a light source, reducing the mass of a light-optical device for a lighthouse, a navigation sign, a buoy, a beacon, simplifying their design, manufacturing technology, thermal control, and thereby, increasing the reliability of navigation equipment, simplifying the technical service during operation.

The design of the proposed light-optical device according to the principle of construction provides a universal approach to any type of navigation equipment, which reduces operating costs, reduces the cost of providing energy sources based on batteries, and if alternative energy sources are available, it will allow them to be calculated taking into account the minimum cost of providing electricity . The versatility and simplicity of the design makes it possible to simplify the training of service personnel.

This technical result is achieved by the fact that the light-optical device of the beacons navigation aids (Fig. 1) consists of a special lens made of pure quartz (or high-purity glass) with a conical groove made in the upper part at an angle of 90 degrees, which allows the light flux , passing through the center of the lens, be reflected in the horizontal plane 360 degrees evenly (2).

One LED matrix (3) or one LED is used as a light source in the light-optical device of beacon navigation aids (depending on the light visibility range required for this type of aids to navigation). Due to the fact that one light source is used for heat removal, a small radiator (4) is required, which leads to a decrease in the overall dimensions of the entire product. The control unit (5) allows you to set the standard characteristics for each navigation object, prescribed in the special edition of the Navigation and Oceanography Department of the Ministry of Defense of the Russian Federation "Lights and Signs" or in the descriptions of navigation equipment on inland waterways. The transparent cap (1) is designed to protect the lens, the base (6) is designed to mount the light-optical device on a beacon, navigation sign, buoy or buoy. This design of the light-optical device of beacon navigation aids, according to the principle of construction, provides a universal approach to any aid to navigation equipment, which reduces operating costs, reduces the cost of providing power sources based on batteries, and if alternative energy sources are available, it will allow them to be calculated taking into account minimal costs for the provision of electricity. The versatility and simplicity of the design makes it possible to simplify the training of service personnel.

Claims (1)
