Description

The invention relates to the field of development of removable lighting devices for installation on vehicles and illumination of their surfaces, mainly for installation on the outer surfaces of vehicles involved in route passenger transportation, for the purpose of external illumination of information route indicators located on the outer surfaces of route vehicles, in the dark Times of Day. Also, the claimed lighting device may be applicable with the aim of providing lighting during the repair of the vehicle and other official and auxiliary tasks requiring additional lighting.

Patent documents are known that describe various lighting devices and fixtures, including removable ones, which are intended to be placed on the external surfaces of vehicles, including those having magnetic parts in their construction for mounting on a metal surface.

Such devices are described, for example, in patents:

US No. US5457614, IPC F21V19 / 00; F21V21 / 08; F21V21 / 092; F21V21 / 096, publ. 10/10/1995 g.

The device contains magnetic mounting material and a light source. The disadvantage is the low attention to the aerodynamics of the structure and the presence of moving parts, which makes the device inapplicable at speed.

US No. US2004100372, IPC B60Q1 / 26; B60Q7 / 00 publ. 05/27/2004

The device contains magnetic mounting material on the base and an integrated light source. The disadvantage is the small diameter of the base with respect to the frontal area of the device, which, when fastened with magnetic attraction of the base material to the vehicle body, can cause the device to tear off due to headwind when the vehicle is moving, which makes the device not applicable at speed.

Another close in purpose lighting device for transport is a projection device described in US patent No. US2011032484, IPC G 03 B 21/14 ; G 03 B 21/30 , publ. 10/02/2011

This is a projection type device, the optical radiation from the source of which is directed to one of the surfaces of the vehicle, as well as the optical radiation from the LED source in the inventive device. The disadvantage is the need for a complex mounting system to hold the device on the vehicle.

With some similarities of the mentioned analogs and other similar lighting devices, including with a magnetic base, the author did not identify a direct analog.

The objective of the invention is the development of a lighting device with aerodynamic properties for installation on the outer front surface of the vehicle, taking into account the typical geometry of the body of the minibus, with the ability to easily mount, disassemble and connect to the vehicle’s electrical circuit and has a light-emitting source with brightness parameters and configuration (direction optical radiation on the bearing surface), sufficient for illumination in the dark information direction indicators located on the same bearing surface of the vehicle body on which the illuminator is installed; The aerodynamic properties of the illuminator should ensure its safe use at operating speeds of public transport, taking into account climatic conditions and air flow resistance.

The technical result is achieved due to the fact that the illuminator of the route indicator is made in the form of an assembly of three main parts of the device: the main forming part is a plastic elongated (in the form of an antenna-console) case, when viewed from the side, it is inclined at an angle that is sharp to the base, and for the most part the length of the cross-section of a narrowed rhombus with an asymmetric die-cutting, increasing downward by the wall thickness, and closer to the base having a cross-section turning into a circle; on one side of the casing, for the most part of its length, a linear LED light source is attached, the main direction of the optical radiation from which due to the shape and angle of inclination of the casing is constantly directed down-side - towards the surface on which the illuminator is fixed; the power cable of the LED source goes from the middle out through the hole in the housing; a strong magnet corresponding to the diameter of the base is attached to the base of the body, holding the device on the metal surface of the vehicle body and providing easy installation and disassembly. Due to the height of the casing, the light source is raised above the illuminated surface to achieve a more uniform and larger exposure area. The housing configuration is designed so that the main vector of optical radiation should be directed to the bearing surface and at the same time perpendicular to the direction of movement of the vehicle; moreover, while viewing the vehicle frontally and to the right (with the illuminator installed on it), the external side of the illuminator body obstructs the built-in light source, but does not block the illuminated surface, which makes it easier to perceive the textual content of the illuminated information route indicator located on the bearing surface next to illuminator.

A linear LED light source is connected to the wire by soldering, the soldering spots are protected by an insulating compound. During assembly of the route indicator illuminator, the wire is passed through an opening in the housing for additional reliable fastening of the wire and the exclusion of turning movements in case of accidental impact on the wire. On the other side of the wire, a cigarette lighter plug is installed to connect to the vehicle’s electrical circuit.

LED strips up to 120 mm long and up to 15 mm wide, having two rows of bright white LEDs combined into one lighting source, suitable for direct connection to a constant voltage of 12V, are recommended as a light-emitting source. The lighter of the route indicator is connected to the power supply by a wire of the required length through the cigarette lighter plug with a fuse or connected directly to the wiring of the vehicle’s internal or external lighting system, directly or via a secure plug connection. In vehicles whose voltage is different from 12V, you must use the appropriate power supply.

Rare-earth magnetic washers with a thickness of 5 mm with a hole for a screw or self-tapping screw showed excellent results in testing the invention in laboratory and field conditions (with a total illuminator height of up to 24 cm), since the force of magnetic attraction in combination with the aerodynamics of the body shape ensure the reliability of the use of the route indicator illuminator on high speeds (wind speed up to 290 km / h in the wind tunnel), and the ratio of the total area of the base of the illuminator of the route indicator with its height allows you to use the height of the building sa as a lever for easy to overcome the magnetic attraction during the dismantling of the illuminator with one hand. A silicone compound is applied to the outside of the magnet to prevent slipping and scratching of the vehicle surface during operation of the illuminator.

The illuminator of the route indicator contains an elongated plastic case 1 (in the form of a console antenna), having for the most part a cross-section of a narrowed rhombus with an asymmetric die-cut, with a wall thickness increasing downward and passing to the base of the antenna in a circle (Fig. 1; Fig. 2); on the one side of the housing 1, for the most part of its length, a linear LED light source 2 is attached with reliable adhesive bonding to the power supply 3 soldered to it, which is passed through an opening 4 in the housing 1; a magnet 5, corresponding to the diameter of its base, is attached to the housing 1 from the bottom with a self-tapping screw 6; moreover, a thin polymer layer 7 having softening and anti-slip properties is applied to the outer surface of the magnet 5. A linear LED light source 2 having a metallized base 8, which serves for strength and heat removal, is glued to the housing 1, which along the entire length except the base has two recesses 9 that form the heat-conducting channels for the LED with the metallized base 8 of the LED source 2 light source 2. The route indicator illuminator is mounted directly on the surface of the body of the route vehicle 10 (Fig. 8), but since the device of the route indicator illuminator is removable and, therefore, can be installed on the surface of the vehicle 10 in different ways, for the intended use, a preferred option is proposed to install the illuminator on a minibus upward (by the type of antenna) (Fig.6), in which the calculated mutual angles of inclination of the base plane the illuminator body and the main plane of the illuminator body provide the optimal location of the illuminator relative to the following parameters:

- the average angle of inclination of the front surface of the vehicle (minibus);

- the direction of movement of the vehicle with the resulting airflow resistance (air resistance is minimized by the perpendicular position of the front rib to the direction of movement);

- the intended location of the information route indicator on the bearing surface of the vehicle (minibus);

- Estimated possible weather conditions, including in the winter season, when the surface area of the upper plane of the device determines the likelihood of freezing (the area on top of the device is minimized, the body has a streamlined pointed top).

An additional possible installation option of the route indicator illuminator on the vehicle surface is also proposed (Fig. 7), in which the device is given a horizontal position forward (like a console). At the same time, the resistance of the oncoming air flow is minimized, but the area of possible freezing from precipitation increases.

The technical result of the claimed invention of the illuminator route indicator is to reduce the resistance of the design of the illuminator to air flow, and therefore, increase its stability on the surface and expand the range of weather conditions and high-speed operation mode; simplification of the installation and dismantling of the illuminator, improving the quality and area of illumination of the bearing surface next to the installed illuminator of the route indicator due to the LED light source and housing configuration raised from the bearing surface, reducing the risk of damage to the paintwork of the bearing surface.

A characteristic feature of the claimed invention is the optical radiation of an LED light source directed to the same surface on which the illuminator is installed, while providing sufficient illumination of the information route indicator of the route vehicle to recognize the information contained therein at night from a distance of at least 15 meters. A lighter, simple and effective in operation and operation, installed next to the route indicator, can be connected in a standard way to the vehicle’s electrical circuit due to the necessary length of wire, and also taking into account the ease of installation / dismantling due to the magnetic principle of fastening, can be easily fixed to any surface of the vehicle means for auxiliary tasks, for example, due to the low power consumption of LEDs - to provide local lighting during vehicle repair on the road conditions. An important characteristic is the minimum resistance area to oncoming air flows and the small area to the side. There is a reduction in visibility for the observer of the light source itself and an improvement in the visibility of the illuminated surface. The polymer anti-slip coating of the mounting magnet has a double function: it enhances the effect of magnetic attraction by eliminating vibration displacements and prevents the erasure of the bodywork from microvibrations.

Since the materials used are selected taking into account strength, weather resistance and moisture resistance, the inventive route indicator illuminator can be operated in a wide range of temperatures and various climatic conditions.

Materials known from the prior art and available in market conditions can be selected with the above characteristics and can easily be used for the manufacture of the claimed invention of the route indicator illuminator both industrial and artisanal, for example, a plastic case can be manufactured in industrial volumes by injection molding machine, or in small quantities - using 3D printer replicators.

The obvious need for commercial vehicles of category "M2" in the indicated solution of the illuminator of the route indicator, combined with its high characteristics of weather resistance, simplicity and universality of operation and maintenance, emphasizes the socio-cultural and economic value of the invention.
