Abstract

The proposed solution relates to automation of control processes, diagnostics, repair and maintenance of railway automation and telemechanics equipment and is used on the railway network of the Russian Federation. The problem is solved by the fact that the proposed device provides the ability to adjust the signaling equipment most effectively use the lighting devices of the stand to adjust the equipment with the ability to control the brightness of the backlight, changing the position of the lighting screen in height and application, if necessary, of additional devices. The device consists of two vertically mounted mounting perforated profiles fixed to the worktop of the regulator’s workplace using clamps located at the bottom of the mounting profiles. Between the mounting profiles, a frame with a light screen is fixed with the possibility of height adjustment relative to the countertop. Pads for mounting additional devices are attached to the mounting perforated profiles. Thus, the proposed device with built-in illumination of the workspace of the controller’s workplace allows you to use energy-saving technologies that provide brightness control, diffuse lighting and the absence of flicker, change the height of the light screen, and also apply if necessary, additional devices (additional lights, a magnifier, a holder for a tablet) to improve working conditions ulirovschika signaling equipment.

Description

The lighting device of the controller’s workplace using energy-saving technologies, providing brightness control, diffuse lighting and the absence of flicker.

Utility Model Description

The utility model relates to automation of control processes, diagnostics, repair and maintenance of railway automation and telemechanics equipment and is used on the railway network of the Russian Federation.

The closest analogue to the lighting device of the controller’s workplace is the RF patent for the invention No. 2449212 of 08/17/2007, “A lamp containing adjustable lighting modules”. The lamp comprises a housing and one or more lighting modules pivotally mounted in the housing. Each of the lighting modules contains a light-emitting element and a corresponding heat sink and output optics for it and is rotatable in the housing. The lamp also contains a longitudinal part for connecting the lighting module, pivotally mounted in the housing for rotation around a longitudinal axis, which is parallel to it. The fastening means for the output optics is adapted to engage the heat sink and the light-emitting element with the help of the fastening element to maintain a thermal connection between the light-emitting element and the heat sink with the location of the optical element with optical alignment with the output of the light-emitting element. The fastener is adapted to engage the substrate of the light-emitting element and apply bonding pressure to it relative to the heat sink and contains one or more latches made so that they extend behind the substrate, engaging it, and are connected to the corresponding one or more mounting protrusions. The heat sink includes one or more mounting tabs. The technical result is the provision of the ability to adjust lighting.

A significant difference is the versatility of the technical means of this lamp, not designed to work with signaling devices, as well as the directional nature of the lighting. Also, the absence of flicker is not specified for this device. The device (taking into account its specifics) has a number of distinctive features that do not allow the use of previously developed solutions. The question of the lighting facilities of the stand for adjusting the signaling equipment with the ability to control the brightness is not taken into account.

The problem solved by the proposed utility model is to enable the signaling system controller to most effectively use the lighting devices of the stand to adjust the equipment with the ability to control the brightness of the backlight, change the position of the lighting screen in height and use, if necessary, additional devices.

The essence of the utility model is illustrated by drawings, which depict:

in FIG. 1 Front view of the device,

in FIG. 2 Rear view of the device.

The composition of the device for placing the elements of the complex at the workplace of the traffic controller with built-in illumination of the workspace includes the following components: two vertically located mounting perforated profiles (1) 700 mm long, between which a frame with a light screen is fixed with the possibility of height adjustment relative to the countertop (7 ) in increments of 50-70 mm. Mounting pads (2) are attached to the mounting perforated profiles for mounting additional devices in order to improve the working conditions of the traffic controller (for example, additional lamps, a magnifying glass, a tablet holder). The light screen (3) based on LEDs, representing a flat design, measuring 550 × 350 mm and a thickness of 60 mm. The front side of the light screen is a diffuser (4) (frosted glass or acrylic), which provides uniform illumination, the brightness control of the backlight (5) is located on the upper edge of the light screen and provides smooth adjustment from 0 to 500 lux and 3 levels of the light spot size. The light screen with mounting profiles is attached to the tabletop of the regulator's workplace using clamps (6) located at the bottom of the mounting profiles.

In FIG. 3 shows a circuit diagram of a backlight control of a light screen.

The principle of operation of the light screen with built-in illumination of the workspace is as follows: the timer IC1 uses pulse width modulation to control the light intensity. The pulse width is controlled by a variable resistor R2. The received signal opens the gate of one or all field effect transistors. The S1-S3 buttons select the work area. The LED strip is connected to the 3rd channels K1-K3. The operating voltage is 12 V. To ensure the required lighting power, three LED strips of at least 0.6 m are used (60 LEDs in the format 3528 or 5050).

Thus, the proposed device with built-in illumination of the workspace of the controller’s workplace allows you to use energy-saving technologies that provide brightness control, diffuse lighting and the absence of flicker, change the height of the light screen, and use, if necessary, additional devices (additional lights, magnifier, holder for a tablet) to improve the working conditions of the signaling equipment regulator.
