Description

The inventive utility model relates to the technique of light signaling, in particular to traffic lights on LEDs and can be used in pedestrian traffic lights.

Known pedestrian traffic light with information board according to patent RU 87552 U1, publ. 10.10.2009, comprising a housing with a translucent screen, behind which is a light source made in the form of a matrix of identical LEDs forming a digital time indicator, a control unit and a power supply. The body is made of two sections located one below the other. In the upper section of the housing there is a matrix of red LEDs glowing, forming a stylized figure of a standing person, and a matrix of green LEDs glowing, forming a digital indicator with a countdown in seconds. In the lower section of the housing is a matrix of green LEDs that form a stylized figure of a walking person. Additionally, for pedestrians with no or limited vision and hearing, the traffic light is equipped with a control unit, which includes elements for automatically adjusting the volume and intermittent sound depending on the duration of the green signal.

The disadvantages of the known device are:

- the lack of a countdown function of the burning time of the prohibition signal of a traffic light, which leads to a decrease in information content and traffic safety,

- the presence of a constant brightness of the traffic light that does not depend on the ambient light and time of day, which negatively affects energy savings at night (if the traffic light is not turned off), or on traffic safety (if the traffic light is turned off at night).

The task to which the proposed utility model is aimed is to increase the informative value of the pedestrian traffic light and, as a result, increase the level of road safety.

The technical result consists in providing pedestrians with information about the burning time of the prohibitory traffic light signal and saving energy resources at night.

The problem is solved, and the claimed technical result is achieved by the fact that in the well-known pedestrian traffic light containing two modules located one below the other modules, in the upper of which there are red LEDs that form a stylized figure of a standing person, and green LEDs of two seven-segment digital indicators and in the lower module there are green LEDs that form a stylized figure of a walking person, as well as a controller, power modules, a block Board,

- the red LEDs are additionally introduced into the lower module, which form two seven-segment digital indicators of the countdown of the burning time of the inhibitory traffic signal,

- the traffic light is equipped with a device connected to the power supply units for regulating the amount of power supply current of the LEDs depending on the ambient light,

- the control unit is supplemented by an automatic function to increase the speed of a stylized human figure in the last three seconds of burning a green traffic signal,

- the control unit is supplemented with an automatic function for automatically adjusting the volume and intermittent sound depending on the time remaining until the end of the burning of the green traffic light,

- a device for controlling the magnitude of the LEDs supply current is made using a photo relay.

Thus, for a safe crossing of the streets, the proposed traffic light arrangement provides pedestrians with the following necessary information: a countdown of the burning time of the digital indicators of the traffic light inhibiting signal located in the lower traffic light module, while a standing stylized figure of a person located in the upper traffic light module is displayed, a countdown burning digital indicators of the permission signal of the traffic light located in the top module of the traffic light at the same time th image stylized figures walking person situated in the lower module of traffic lights, the velocity of a walking human figure in the last three seconds of burning digital indicators allowing traffic signal increases. In addition, the device is equipped with an audio signal, the discontinuity and volume of which increases towards the end of the burning of the traffic light, which is important for citizens with low vision. At different times of the day, the photo relay controls the brightness of the LEDs, eliminating the glare of pedestrians and drivers, and also saves the energy needed for round-the-clock work of a pedestrian traffic light.

The essence of the proposed technical solution is illustrated by drawings, where:

figure 1 presents the appearance of a pedestrian traffic light,

figure 2 is a structural diagram of a pedestrian traffic light. The device comprises, installed on a column before a pedestrian crossing, a traffic light consisting of two modules located one below the other: the upper module 1 for the red traffic signal and the lower module 2 for the green traffic signal. Each module (1 or 2) consists of a housing 3, and a protective glass 4, made of impact-resistant material - polycarbonate. Inside the upper module 1, red LEDs are installed, forming a stylized figure 5 of a standing person and green LEDs of two seven-segment digital indicators 6 with a countdown in seconds. Inside the lower module 2, green LEDs are installed, forming a stylized figure 7 of a walking person and red LEDs of two seven-segment digital indicators 8 with a countdown in seconds. Modules 1 and 2 through the housing 3 are connected to the controller 9 installed on the column, which gives commands for their illumination. The traffic light is equipped with a device for controlling the amount of LED current in the form of a photorelay 10 connected to power supplies 11 and 12 of each of modules 1, 2. Sound signal is sounded by a sound siren (not shown in the figure) with automatic volume control and intermittent sound depending on the time remaining until the end of the burning of the green traffic light, and the increase in the speed of movement of the stylized human figure in the last three seconds of burning the green traffic light is carried out according to the control ignalu from the microprocessor (on ris.ne shown) installed in the control unit 13.

The device operates as follows.

When the pedestrian-enabled traffic signal arriving at module 2 from the traffic light controller 9 is turned on, the digital indicator 6 is sequentially lit by the green LEDs in the upper red module 1 and shows the time in seconds remaining for the pedestrian to cross the roadway, at the same time the bottom green module 2 on the scoreboard is highlighted with green LEDs a stylized figure 7 of a walking person, the speed of which increases in the last three seconds traffic lights. At the beginning of the countdown, an intermittent sound signal is generated with a frequency of 3.0 kHz ÷ 4.5 kHz, which increases the sound frequency three seconds before it turns off. After the zeroed indication appears in the upper module 1, the prohibitory transition signal for pedestrians in the form of a stylized figure 5 of a standing person, made of red LEDs, is turned on in this module, and in the lower module 2, the red LEDs are sequentially displayed on the scoreboard Glow digital indicator 8, showing the time in seconds remaining before the start of the movement of the pedestrian, while the sound signal is not emitted. The photo relay 10 gives commands to power supplies 11 and 12 depending on the ambient light: at night, the brightness of the LEDs decreases from a given value, in order to save energy, and in the daytime it increases to a predetermined value.

Safety glass 4 ensures the tightness of the device. The power display for the pedestrian traffic light is supplied from an alternating current network with a voltage of 220 V and a frequency of 50 Hz.

Thus, the proposed technical solution of a traffic light with an additional countdown showing the numbers in seconds remaining before the start (module 1) or end (module 2) of pedestrian traffic, and adjustable brightness of the LEDs depending on the time of day increase the performance and high information content of the product . Road safety is enhanced.
