Description

The utility model relates to traffic control devices and can be used to organize traffic at intersections and pedestrian crossings.

According to international and Russian technical requirements for traffic lights, the signals regulating the movement of vehicles must be monochromatic, round in shape and each should be located in its own section of the traffic light.

The use of LED emitters in modern traffic lights with lenses that form a narrow luminous flux significantly improves the visibility of traffic signals from drivers over long distances, and also allows you to give each signal an individual shape and place all the traffic signals in one section. In addition, in the same section, it is possible to additionally set a countdown indicator for the duration of the action of the enable and disable signals. Until recently, mainly digital displays placed in additional sections or in the central (yellow) section of a three-section traffic light were used for counting time.

It is known single-section "Display device for traffic lights" according to patent FR No. 2875632 (A1), which includes colored LED radiation sources that alternately form a red cross (traffic inhibit signal), a yellow triangle (standby signal) and a vertical arrow (traffic permit signal). This traffic light is intended mainly for work on high-speed country roads.

The disadvantages of the device are the lack of signals that allow movement in various directions, inefficient use of the signal section area, and the lack of the ability to determine the remaining time of the signals.

Also known is the "Transport flat LED traffic light" according to patent RU No. 2660201, which is a traffic light of a traditional three-section design, in which an annular LED scale is installed along the perimeter of each section, providing a countdown of the remaining display time of the round light signal of the section, by turning off the LEDs sequentially or counterclockwise arrows until a closed loop is formed from the LEDs off.

The disadvantages of a flat LED traffic light are its large weight and dimensions, as well as reduced wind resistance of a three-section design. In addition, drivers may have difficulty distinguishing the ring scale at large distances from traffic lights.

Also known is "Single-section LED traffic light" according to RU patent No. 2468444, with radiation sources installed in its section in the form of two-color (red and green) LEDs that form a series of emitting squares of rectangular, triangular and octagonal shapes, which, with various switching options under the control of the controller, display the following signals: “traffic ban”, “waiting”, “traffic permit -forward”, “traffic permit - turn right or / and left”, “move off the occupied lane to the right or left”. At the bottom of the traffic light section, a digital display is installed to display a countdown of the operating time of each supplied signal.

The disadvantages of the "Single-section LED traffic light" are the difficulty of forming a narrow light flux, providing distinguishability of characters at a long distance, the difficulty of reading digital symbols of a digital display, for example, at high vehicle speed. In addition, an excessively large section is used in this traffic light, a substantial part of which is not used to accommodate radiating elements.

The closest analogue in technical essence to the claimed utility model is a single-section LED traffic light according to patent No. 2468444, adopted as a prototype.

The task to which the claimed technical solution is directed is to create a universal single-section city traffic light that provides clear recognition of reproduced light signals, as well as the remaining time of validity and prohibition signals, including drivers with color perception impairments.

This problem is solved as follows. The traffic light is made in the form of one section with radiating elements of three different colors, which make up the signals in the form of individually distinguishable figures. A two-color countdown indicator is placed along the perimeter of the section.

A utility model is illustrated in FIG. 1 ... FIG. 8, which shows a traffic permission signal (Fig. 1), a traffic ban signal (Fig. 2), a traffic ban warning signal (Fig. 3), a section of a traffic light with a countdown indicator (Fig. 4), signal options movement permissions (Fig. 5 ... Fig. 7) and a section diagram with a two-row countdown indicator (Fig. 8).

The motion resolution signal is a square (Fig. 1), composed of green radiating elements, with diagonals of the maximum possible size for the signal section, oriented vertically and horizontally. The traffic inhibit signal is two crossed bands of red radiating elements of the maximum possible size for the signal section (Fig. 2). The warning signal of the prohibition of movement, is a ring of yellow radiating elements, the maximum possible for the signal size section, located on the periphery of the section (Fig. 3). A traffic permission warning signal is a combination of traffic prohibition signals and traffic prohibition warning signals that are simultaneously turned on.

Along the perimeter of the section there is a countdown indicator in the form of a series of alternating green and red radiating elements installed around its perimeter (Fig. 1, Fig. 2).

In FIG. 4 schematically shows a section of a traffic light with emitting elements of red, green and yellow colors that make up the signals of a traffic light and a countdown indicator.

Switching the signals of a traffic light takes place under the control of the controller according to the cyclogram embedded in it.

The green radiating elements of the motion enable signal are turned on simultaneously with the green radiating elements of the countdown indicator (FIG. 1). At the same time, the countdown indicator displays the remaining time of the motion resolution signal by sequentially turning off the green emitting elements from top to bottom, alternately from the left and right sides of the indicator.

At the end of the duration of the motion enable signal, the yellow emitting elements of the traffic ban warning signal of FIG. 3. Next, the red radiating elements of the motion inhibit signal are turned on, at the same time the red radiating elements of the countdown indicator are turned on (Fig. 2). At the same time, the indicator displays the remaining time of the motion inhibit signal by sequentially turning off the red radiating elements from top to bottom, alternately from the left and right sides of the indicator.

Then, together with the red emitting elements of the motion inhibit signal turned on, the yellow emitting elements are turned on, which signals the upcoming transition to the motion permit signal.

Subsequently, the controller repeatedly repeats the described sequence diagram of the traffic light.

Additionally, to emphasize the warning signals, the following is provided. During the operation of the motion inhibit warning signal, the red elements of the motion inhibit signal from the center to the periphery are sequentially turned on. During the operation of the motion permission warning signal, the red elements of the traffic inhibit signal from the periphery to the center are sequentially turned off.

For intersections at which it is necessary to display the permitted directions of movement instead of a signal in the form of a green square, several variants of waveforms of the permission of movement are provided in the form of one or two arrows indicating the direction of movement "forward" (Fig. 5), "right", "left", "Forward and right" (Fig. 6) and "forward and left" (Fig. 7).

To improve the distinction between the driver of the radiating elements of the countdown indicator, a traffic light option with a multi-row indicator and an increased number of emitters is provided. A traffic light with a two-row indicator is shown in FIG. 8.

To provide a better distinction between drivers of signals in the proposed utility model of a traffic light, a luminous ring of permanently activated elements, different in color from the main signals, for example, white or blue, is introduced along the outer perimeter of the section.

To transmit information messages to vehicles approaching the traffic light in order to reliably inform drivers about traffic signals and traffic conditions, as well as to provide information support for the automatic driving mode, the radiating elements of the signal section are capable of modulating their radiation.

As emitters in a traffic light, widespread color LEDs with lenses that form a narrow light flux can be used. The traffic light section can be composed of red, green, yellow, and white or blue LEDs of various sizes depending on the required diameter of the section, which can be found in a row of 4, 8 and 12 inches (100, 200 and 300 mm, standardized for traffic lights) ), and outside it. Lenses can be made both individually for each LED, and in one or more group blocks of lenses.

The main provisions of the proposed utility model were set out in the article “On Road Traffic Lights of the Future” in the journal “Semiconductor Lighting Engineering” No. 3, 2019, signed in print on 05.21.2019. The article received a diploma of the Golden Photon of the Eurasian Prize in Lighting Engineering and Electrical Engineering in the nomination Ray of Light.

The technical result of the proposed solution is to increase the information content of the traffic light, increase the ability to distinguish reproduced light signals, in particular, drivers with impaired color perception.
