However, the device has low reliability and durability. The design is complex and unsuitable for the effective regulation of city traffic.

Also known is the decision of the TRAFFIC SECTION, Date of filing of application 2000.03.06 IPC G08G1 / 095, No.2000105498.

The traffic light section comprises a housing with a sunshield, an optical device mounted in the housing, including a light source, a reflector and a color light filter-diffuser, the light filter being made so that the rays can be reflected from external light sources in such a way that they do not fall on road users, this diffuser is mounted obliquely; the outward-facing surface of the diffuser is flat; the light filter diffuser is made in the form of a cylinder with an oblique cut facing outward;

the angle of inclination of the outward facing surface of the filter-diffuser is selected from the ratio:

0.5arctg (D / L),

where D is the diameter of the projection of the light filter-diffuser onto a plane perpendicular to the radiation axis of the traffic light section;

L is the distance in plan from the end face of the free end of the anti-sun goat to the light filter-diffuser;

the outwardly facing surface of the light filter-diffuser has a parabola profile, the focus of which in the longitudinal plane of symmetry of the traffic light section is geometrically aligned with the extreme point of the inner surface of the sunshield;

the light filter diffuser is made in the form of a cylinder with a slice representing the surface of said profile.

Also known is the decision Single-section traffic light, Application filing date 2001.06.05, IPC Basic Index G08G1 / 095, No. 2001115026; The single-section traffic light is a rectangular cabinet with dimensions 300300150 mm, characterized in that all three colors of the traffic light - red, yellow, green - are mounted in one rectangular case, compact complete cells are provided inside the case for the convenience of replacing them in case of malfunctions, the lighting area is increased traffic light for each color.

However, the device has low reliability and durability; it is of little use for the effective regulation of city traffic.

Also known device according to A.S. USSR No. 151230, IPC G08G 1/095; 03/28/1960; this decision, according to the applicant, can be considered as a prototype. The set of features known from the prototype.

A traffic light containing a casing, an octagonal set inside the casing, a prism rotatable from the movement mechanism and the electric drive, with two red, four yellow, two green filters installed on its faces, located inside the prism, a constantly switched on light source, a control circuit acting on the electric drive and a mechanism for moving the prism at an angle that allows light to pass through the corresponding light filter of the traffic light.

However, the device has low reliability and durability; it is of little use for the effective regulation of city traffic.

The technical problem to be solved is to simplify

design, operation, cost reduction, reliability and durability, more efficient regulation of the city traffic flows and is ensured by the following set of essential features.

A traffic light comprising a light source installed in the housing, a constantly switched on light source, a window for passing light installed inside the housing between the light source and the window rotating around the light source in start-stop mode, a drive screen that controls the electrical circuit, and around the perimeter of the screen in a certain sequence of colors, color filters are placed; wherein

the light source is filled with gas discharge,

the screen is made in the form of an tetrahedral prism or cylinder, the start-stop mode of the drive is selected with the ability to rotate and fix the screen in at least two positions, the number of light filters placed on the screen is at least two;

in the direction of rotation of the screen, the color of the filters is selected in the sequence: red, green;

visually perceptible inscriptions and / or pictograms are placed in the direction of light passage;

in the direction of rotation of the screen, the color of the filters is selected in the sequence yellow, red, yellow, green.

The proposal is illustrated graphically, where the positions indicated:

1-case;

2-light source;

3-case window;

4-hub light;

5-swivel screen;

6-color filters;

The device operates as follows.

The light source 2 (gas discharge lamp) is constantly connected to the power source and creates a luminous flux in the direction of the window 3, which, passing through the filter 6 creates a corresponding light signal in the window. At the command of the controller, the screen drive rotates it at a certain angle and fixes it in this position until the next controller signal. The number of filters and the angle of rotation of the screen depends on the number of required signals. For example, for three signals: red, yellow, green, 4 filters are required (yellow, red, yellow, green) and the rotation angle will be 90 degrees. For two signals (pedestrian option:) two light filters: stand, go and / or corresponding icons and a rotation angle of 180 degrees, or four light filters (stand, go, stand, go) and a rotation angle of 90 degrees.

Additional Information

Now, for example, 878 traffic light posts have been installed on the streets of St. Petersburg.

Many traffic lights are old-style and do not comply with GOST for a long time, therefore

it is not surprising that they often break down and thereby inhibit intense

traffic flow on the road ...

- Today in St. Petersburg about 80% of traffic lights are necessary

replace, ”says the chief civil engineer. SMEP Ministry of Internal Affairs in St. Petersburg and Leningradskaya

area Mikhail LUNEV. - Every day we receive from 50 to 100 applications for them

repairs.

You have to constantly change the blown bulbs, repair the cable.

Cases of theft of socles, which are made of silumena - their

willingly take non-ferrous metal receivers. Now we began to make

black iron plinths.

A lot of money is being spent on repairs. Column recovery costs 2700

rubles. Eye replacement - from 1800 to 2200; add replacement costs here

cable, the work of the installers ...

In bright sunlight, when the rays fall on a traffic light,

Fonton effect: it seems that all eyes are lit at the same time. TO

In addition, special incandescent lamps must be screwed into these traffic lights,

which shine 3,5 thousand hours. But due to lack of money, they often burn

ordinary household light bulbs that burn out much faster ...

However, we have more advanced traffic lights. One of them to our city

presented by the Austrian company Futurit, he works on the corner of the 1st

Krasnoarmeyskaya street and Moscow avenue. Unlike domestic

appliances in the Austrian light bulb shine without interruption 7.5 thousand hours, and eyes

have reflective lenses and anti-phonon grids - this device allows

the driver to correctly determine the burning signal in any weather.

At the exhibition in our city, the Motorway and parking similar

Traffic lights were demonstrated by representatives of the Austrian company Swarco. They are

stated that they were very glad that on the corner of Moskovsky Prospect and Obvodnoye

the channel is still worth their equipment (motorists know that these eyes

visible in any weather) and admitted that they are very interested in

cooperation with our city.

By the way, Moscow has already managed to solve the traffic light problem throughout the capital

Bright electric regulators are installed. Of course, white stone is a city

both in snow and in rain

In many countries, along with lamp, LED traffic lights are used. In St. Petersburg, experts LOMO, Physicotechnical Institute named after Ioffe and Svetlana also developed similar devices. They are distinctly different from their predecessors. Each of their eyes consists of hundreds of stashny droplets in which LEDs are located. They shine for 50 thousand hours. Moreover, even if several LEDs fail, the traffic light will regularly perform its work. The brightness of the signals does not depend on the level of lighting: the light of an electric regulator can be seen in snow, in rain, and even in fog.

There are several such traffic lights on the banks of the Neva: one of them is installed at the intersection of Moscow and Detskoselsky avenues. There is a LED traffic light for about $ 1,000, Austrian - not cheaper. Therefore, the city, unfortunately, is not yet able to put them at every intersection
