Description

The utility model relates to lighting devices, namely to devices that are fixedly installed mainly in the form of one continuous strip in order to transmit warning light signals for passengers and staff of train stations, subways or other places where these light signals are appropriate to mark the edge of the platform and inform passengers and personnel about the possible danger.

The utility model can be used as a warning light strip, which is usually located along the entire length of the platform and at a certain distance from the edge of the platform, for example, railway or subway, in order to ensure the safety of passengers, or in a depot to ensure the safety of technical personnel during time of maintenance of trains. Among other things, the utility model can be used not only as an independent unit, but also in conjunction with previously installed separate point luminous elements. The light signal strip is a modern alternative to the usual warning stripes, which have a number of disadvantages, for example, they are hardly noticeable in poor general lighting of the room, and also almost invisible for the visually impaired category of citizens.

From the prior art, a LED lamp is known (RF patent RU2610402, publ. 09.02.2017, IPC F21V29 / 83, F21V29 / 70, F21S8 / 00), containing a first body and a second body made of heat-conducting material in the form of hollow profiles with open end parts , an end connector, and two end caps made of thermal insulating material and having ventilation holes therethrough. The luminaire additionally contains a third body made of a heat-conducting material, a sealed power source, at least one fastening means and at least one optical unit with LEDs. The first body and the second body are connected to each other from the end parts through an end connector. The other two end portions of the first and second housings are closed with front and rear end caps. The second body has an open lower part, which is closed by the third body, to which is attached a sealed power supply located in the cavity of the second body. The fixing means is connected to the first and second housings and is configured to attach the LED lamp to an external element. The third body is connected to the rear end cap and end connector via detachable connections that are capable of detaching the third body to replace the power supply.

The disadvantage of this known lamp is its complex design, containing many elements that complicate their disconnection, for example, if it is necessary to repair the lamp and the subsequent connection.

Also known is a LED lamp for a platform (US patent US9803807, publ. 10/31/2017, IPC F21K9 / 278, F21V23 / 02, F21V23 / 00), which contains a lamp housing, a removable LED lamp module, a base for mounting a printed circuit board having the first and a second groove and a mounting protrusion formed on its underside. The body has protrusions formed on the upper vertical cut of the edge of the body, and the protrusions are made with the ability to connect with the first and second grooves. Also, the housing has a mounting protrusion extending from its inner side surface, and a hole is made in it, located in such a way that the fastening device is inserted through the hole into said mounting protrusion.

The disadvantage of the described LED luminaire is the need to use fasteners such as screws, which complicates the installation and disassembly of the luminaire.

The closest analogue of this utility model is a LED lighting device according to the publication of international application WO2017154906A1 (publ. 09/14/2017, IPC F21V3 / 02, F21V19 / 00, F21S2 / 00), including a light-emitting unit located in the lamp housing, a long substrate with a plurality of light-emitting elements, a long flat plate portion on which the light-emitting element substrate is disposed, a fixing portion disposed on the flat part of the light-emitting element for fixing the light-emitting element substrate, and a long tubular resin cover for covering the light-emitting element substrate. The cover encloses the light-emitting element substrate in cross-section, and the cover and / or the flat portion of the plate is bonded on the surface to the light-emitting element substrate.

The disadvantage of the closest analogue is the complexity of manufacturing the described structure, the difficulty of replacing the LED lamp in case of a malfunction, unreliability of fastening the end connections of the light-emitting unit, since with a large external load on the structure itself, its parts can be disconnected in the end part of their fastening.

Thus, there is a problem of developing a luminaire in the form of a signal strip, which would ensure safety both for passengers on dangerous sections of train traffic and for technical workers while servicing train carriages in a depot, as well as easy installation and dismantling of its emitting part, would allow it is easy and convenient to protect the emitting part from the external environment.

The technical result to be achieved by the claimed utility model is to create a luminaire design that would increase the strength and reliability of the luminaire design, taking into account the conditions of its use, while simplifying its assembly and disassembly.

The problem is solved, and the claimed technical result is achieved by the fact that the luminaire comprises a luminaire body of an essentially rectangular cross-section, having a lower wall and two side walls extending from it, in which a removable profiled module case with a lighting module with light sources placed on it is installed , a clip for fixing the profiled module body in the luminaire body, and a diffuser. Fixing the lighting module is necessary because the luminaire can be installed in places with increased vibration. The profiled body of the module includes a horizontal section on which the lighting module is located, sloping sections extending to both sides of the horizontal section, and vertical sections, each of which extends from the corresponding inclined section. These vertical sections extend substantially along the side walls of the luminaire body. The diffuser is installed between the inner surfaces of the vertical sections and serves to evenly distribute the luminous flux from the light sources of the lighting module over the entire area of the lamp.

The described design of the luminaire allows you to easily and quickly install and dismantle its emitting part from the luminaire body, including a profiled module body with a lighting module with light sources placed on it, for example, for replacing them, while ensuring reliable fixation of the said emitting part in the luminaire body. The luminaire itself can be installed in a embedded profiled body, for example, on a platform, preferably made of an aluminum material, and, if necessary, additionally fixed therein by means known to a person skilled in the art.

The solution to the problem and the achievement of the claimed technical result are also possible in private versions of the claimed lamp.

So, at the junction of the inclined sections and vertical sections, a groove can be made, where at least a part of the diffuser surface, facing the inside of the lamp housing, for example, its end part, enters, which provides protection against dust and dirt from entering the profiled module housing. In addition, a sealing means, such as an adhesive layer, a rubber seal, and the like, may be provided in the groove. In addition, the surface of the luminaire diffuser facing the inside of the module housing can at least partially contact the sealing means. Also, in addition, a transparent compound can be placed over the lighting module to protect and seal it.

It is preferable if the diffuser is installed in the spacer between the inner surfaces of the vertical sections so that it is possible to press the vertical sections against the corresponding side walls. In this case, the outer surface of the diffuser facing away from the lamp housing is preferably flat or convex.

Further, the utility model, as well as some of its possible embodiments, are explained in more detail with reference to the figures, where:

in fig. 1 shows a general view of the luminaire in the form of a signal strip with an open end part;

in fig. 2 shows a cross-section of an embodiment of the luminaire;

in fig. 3 shows a cross-section of an embodiment of a luminaire;

in fig. 4 shows a cross-section of an embodiment of the luminaire.

FIG. 1 shows a general view of the claimed luminaire in the form of a signal strip, which comprises a luminaire body 1 of a substantially rectangular shape. The luminaire body 1 is made mainly of an aluminum profile or other material that provides lightness of the structure, as well as a high degree of protection from the environment with the possibility of connecting or, otherwise, joining several luminaires into a single line of the signal strip. In addition to the above required material properties, it must also provide strength in order to avoid possible deformations during operation.

In the luminaire housing 1, a profiled module housing 9 is installed, on which the lighting module 5 is located, closed from above by a diffuser 15. The luminaire itself is installed, for example, in an appropriate embedded profile (or box) on a platform or other surface and fixed in it in any known way.

From the bottom wall 2 of the housing 1 of the lamp on each side there is a side wall 3 (see Fig. 2), essentially perpendicularly up to the bottom wall 2. Each side wall 3 on each of its outer sides can be made with a flat outer surface, so and have depressions and / or protrusions of a certain configuration, as exemplified in FIG. 2–4, in order to fix the luminaire body 1 in the above-mentioned embedded profile, as well as for connecting several luminaires into one signal strip. A person skilled in the art will understand that the design features of the profile of the outer part of the side walls 3 are determined by the appropriate means of connecting adjacent lamps and the lamp body 1 with the embedded profile.

Inside the luminaire body 1, on the lower wall 2, there is a retainer 4, made with the possibility of fixing the profiled module case 9, in which the lighting module 5 is located. The retainer 4 fixes with its upper part the horizontal section 8 of the profiled module case 9 and at the same time makes it easy to detach it. Fixation of the profiled housing 9 of the module, and with it, respectively, of the lighting module 5, may be necessary, since the luminaire is intended, among other things, for operation in places with increased vibration.

The lighting module 5 contains a plurality of light sources 6, for example, LEDs, on top of which an optically transparent compound 7 can be applied to seal them, which serves, inter alia, for additional fixing of the lighting module 5 in the profiled housing 9 of the module.

As mentioned above, the lighting module 5 is located on a horizontal section 8, which is part of the structure of the profiled module body 9, which, in turn, is located inside the lamp body 1. From the horizontal section 8, the inclined sections 10 extend in both directions, and then - the vertical sections 11, each of which departs from the corresponding inclined section 10, as shown in Figs. 2-4. In this case, these vertical sections 11 extend substantially along the side walls 3 of the housing 1 of the lamp, adjoining closely or with a small gap to the inner surfaces 14 of the side walls 3.

The presence of inclined sections 8 in the profiled housing 9 of the module, firstly, avoids limiting the luminous flux from the light sources 6. Secondly, they provide the elasticity of the profiled module body 9, allowing it to be installed into the luminaire body 1, when the vertical sections 11 are pressed against the corresponding inner surfaces 14 of the side walls 3, thereby providing additional fixation of the profiled module body 9 in the luminaire body 1 and lightness dismantling it.

Thus, the reliability of fixation and, at the same time, the simplicity of the operations of installation / dismantling of the profiled housing 9 of the module (and therefore of the lighting module 5) in the housing 1 of the luminaire is ensured both by the presence of a retainer 3 engaging with the horizontal section 8 and by the adjoining of the vertical sections 11 to the inner surfaces 14 of the side walls 3.

The profiled housing 9 of the module can be an aluminum profile.

Grooves 12 may be formed at the junctions of the sloped portions 10 and the vertical portions 11, as shown in FIG. 2, 4, into which a part of the surface of the diffuser 15 facing the inside of the luminaire housing 1, in particular its end part, as shown in FIG. 4. Additionally, a sealing means 13 can be installed in the grooves 12 to improve the tightness of the structure and to additionally fix the diffuser 15 located between the inner surfaces 14 of the vertical sections 11, as shown in FIG. 3 for the case of a flat surface of the diffuser 15 facing the inside of the lamp housing 1. In addition, for better fixing of the profiled housing 9 of the module and improving the tightness of the entire structure of the luminaire, the diffuser 15 can press the vertical sections 11 to the corresponding inner surfaces 14 of the side walls 3.

The sealing means 13 is an adhesive layer, a rubber seal or other suitable element of a suitable material.

The diffuser 15 is predominantly made of polycarbonate, the surface of which can be flat (Fig. 2, 3) or curved (Fig. 4). The diffuser 15 serves to evenly distribute the luminous flux from the light sources 6 over the entire area of the lamp.

The claimed lamp works as follows.

In a box or embedded profile, installed on a platform or other surface, one or more luminaire bodies 1 are placed in series, fixing them to each other, as well as in the box itself or embedded profile. Next, the supply line for the lighting module 5 is supplied. The end parts of the lamp housing 1 are closed with end caps, if necessary, fixing them with screws or other means. A profiled module case 9 is installed in the luminaire body 1 with the lighting module 5 placed in it in advance and, if provided, with the compound 7 and / or sealing means 13. Next, the lighting module 5 is connected to the supply line. Then the diffuser 15 is installed in the profiled housing 9 of the module. The lamp is switched on and off using the control system.

Thus, the claimed utility model provides advantages when using a signal strip luminaire, which consist in ease of assembly, installation, and further operation of the structure. The light strip is an efficient and economical replacement for standard light strip due to the degree of protection against environmental influences.
