Description

The invention relates to lighting and can be used to regulate the movement of motor vehicles.

Known traffic light (AS No. 402055 USSR; G08g 1/095; publ. 10/12/1973), consisting of a housing with windows, a drum and a mechanical drive, in which on the outer surface of the drum along the perimeter are mounted vertically in two rows of color filters different lengths.

Known traffic light (AS No. 842919 USSR; G08G 1/095; publ. 06/30/1981), containing a housing with windows and diffusing lenses. A light source and a casing with holes are mounted inside the housing, which are connected to the diffusing lenses by means of light guides. On the outer surface of the casing, movable dampers with holes are installed, connected on one side with springs, on the other, with an actuator. The drive of each damper is associated with a traffic light control system.

Known traffic light (AS No. 1672504 USSR; G08G 1/095; publ. 08/23/1991), containing the upper and lower parts of the body, a gas-discharge illuminator, an octagonal rotary prism, on the edges of which are fixed in pairs opposite each other two red, two green , and in the intervals between them there are four yellow light filters, a support sleeve, a drive, a magnetically controlled relay, permanent magnets, a stator current winding, a stator voltage winding, an external commutator.

The disadvantages of these structures is the lack of the possibility of installing additional sections of the traffic light, allowing you to select separate left and right turns in the traffic light cycle.

Known traffic light type T.1.l, consisting of separate sections with an optical device, each of which is intended for a specific signal, interconnected by threaded hollow bushings through which wires are passed (Kremenets Yu.A., Pechersky M.P., Afanasyev MB Technical means of organizing traffic. Textbook for universities. M., 2005. 279 p.). The section is a housing with a cover and a sun shield made of sheet steel or impact-resistant plastic. The optical device is mounted in the cover and consists of a reflector, a color filter, a rubber seal ring and a movable glass with an electric lamp. In the lower section there is a distribution block for connecting power and wiring inside the traffic light. On the left, an additional section with an arrow “to the left” is attached to the lower section using a threaded hollow bushing.

The disadvantage of a type T.1.l traffic light is the inability to operate in the adaptive control mode with a change in the number of traffic light phases. For example, with a low intensity of left-turn traffic (up to 120 vehicles / h), there is no need to select the left turn at the intersection, that is, there may be no left-turn section; at a high intensity of left-turn traffic (more than 120 vehicles / h), for example, during rush hour, it is necessary to highlight the left turn.

Known traffic light (Pat. No. 2491648 RF; G08G 1/095; publ. 08/27/2013), consisting of a housing with a cover and a sun visor made of sheet steel or impact-resistant plastic. An optical device is mounted in the cover, consisting of a reflector, a color filter, a rubber seal ring, a movable glass with an electric lamp, fasteners, threaded hollow bushings, a distribution block for connecting power and wiring, an additional section installed with the ability to rotate 180 ° on brackets, an electric drive turning the section.

The disadvantages of this design of the traffic light are its large dimensions and the additional space required for turning the section, which makes it difficult to install a traffic light on the same support for the opposite opposite direction.

The closest in technical essence to the proposed invention is a transport traffic light of type T.1.pl1 (LED traffic lights. Access mode: http://promsignal.com/categories/transportnye-svetofory), lightweight design, flat, consisting of a base, on which has three separate sections of emitters: red, yellow, green, and two additional sections of turns: left and right, as a light source in which LEDs are used, equipped with a voltage stabilizer, sun visors, nodes and metal overhead mounts on a support or console, allowing the installation and adjustment of the traffic light in the vertical plane. Taken as a prototype.

The problem to be solved by the invention is to expand the operational capabilities of a traffic light.

This is achieved by the fact that in a transport traffic light, lightweight, flat, consisting of a base, on which three separate sections of emitters are fixed: red, yellow, green, and two additional sections of turns: left and right, in which they are used as a light source LEDs equipped with a voltage stabilizer, sun visors, assemblies and metal overhead mountings on a support or console, allowing the installation and adjustment of the traffic light in the vertical plane, according to the invention, the base is made in the form of a square, one of the diagonals of which is located vertically, and the emitter sections are located in the vertices of the square and are made in the form of directional arrows of the same shape and size, in which red and green LEDs are installed in a checkerboard pattern, and the forward direction arrow is located at the top of the square, the opposite direction - at the bottom of the square, directions to the right and left - respectively in the lateral vertices of the square; the section of yellow glow color is made in the form of a circle and is located on the base of the square in the center between the sections of the direction arrows; the sun visor is installed over the upper half of the base and is made in the form of a gable canopy.

FIG. 1 shows a general view of a traffic light, front view; in fig. 2 - the same, side view.

Transport traffic light, lightweight design, flat, consists of a base 1, made in the form of a square, one of the diagonals of which is located vertically, and the sections of the emitters are located at the tops of the square and are made in the form of direction arrows of the same shape and size, in which in a checkerboard pattern LEDs of red and green luminescence are installed, and the arrow-pointer of the forward direction 2 is located at the top of the square, the opposite direction 4 - at the bottom of the square, directions to the right 3 and left 5 - respectively, in the lateral vertices of the square. Section of yellow glow color 6 is made in the form of a circle and is located on the base of the square in the center between the sections of the direction arrows. Above the upper half of the base 1, a sun visor 7 is installed, made in the form of a gable canopy. The transport vehicle is equipped with a voltage stabilizer, assemblies and metal overhead mountings on a support or console, allowing the installation and adjustment of the traffic light in the vertical plane (not shown in the figure).

A traffic light can work as follows.

A traffic light is installed before crossing highways. If it is necessary to allow movement in the forward, opposite and right-hand directions, the green color of the glow of the sections of the straight 2, opposite 4 and right 3 directions is turned on. If the left turn is prohibited, the red light color of section 5 is turned on. To organize a left turn in the cut-off mode, the red light color of section 4 turns on, informing the driver about stopping the oncoming traffic, and the green light color of the left turn section 5 turns on. When the traffic light control phase changes, it turns on in In the blinking mode of operation, the yellow section of the light is 6, then, for example, the red light is the section of the direct 2, opposite 4, right 3 and left 5 directions. The driver approaches the intersection and stops the car in front of the stop line at the prohibiting traffic light signal. In this phase, the movement of vehicles is carried out along the intersected street or road. Further, when the phase of traffic light regulation is changed, section 6 is switched on in the mode of blinking yellow light, then sections of direct 2, right 3 and opposite 4 directions turn on in green. The traffic light control cycle is repeated.

Turning on the red or green light of the section of the opposite direction 4 allows the driver to understand that the oncoming flow of vehicles is stopped, and it is possible to safely make a left turn. Informing the driver about the state of the oncoming traffic in this way will reduce the start delay time at the intersection and reduce the queue of cars in front of the intersection.

The traffic light can also operate in the mode of changing the traffic light regulation cycle with the allocation of left-turn traffic in a separate phase.

For example, with an increase in the intensity of left-turn traffic more than 120 vehicles / h, information from the vehicle detectors is sent to the road controller, which changes the structure of the cycle and the duration of traffic light signals. In the traffic light cycle, the left turn is highlighted, and the arrow-indicator of the left direction section 5 is lit in green, that is, the traffic light operates in the mode of the left turn section. When the intensity of left-turn traffic decreases to less than 120 vehicles / h, the information from the vehicle detectors is sent to the road controller, which gives a signal to change the structure of the traffic light cycle, and the traffic light operates as usual.

The positive effect of using a traffic light of the proposed design will be that informing drivers about the state of the oncoming traffic flow will ensure the safety of the left turn and traffic at the intersection as a whole, reduce the time of start delays and the queue of vehicles at the intersection. In addition, the movement of traffic flows in the adaptive control mode with the ability to change the structure of the traffic light cycle depending on the traffic intensity of vehicles will increase the throughput of the controlled intersection and reduce emissions of pollutants into the atmosphere from road transport.
