Description

The utility model relates to control devices, in particular, traffic lights, and can be used to organize the movement of vehicles, for example, railways, by installing vehicles along the route and allowing, prohibiting the movement of vehicles on any part of the track, as well as for information purposes.

A single-section traffic light is known, which is a rectangular cabinet with dimensions 300 × 300 × 150 mm, while 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 convenient replacement in case of malfunction , the area of illumination of traffic lights for each color has been increased (see application for the grant of a patent of the Russian Federation for invention No. 2001115026, IPC G 08 G 1/095, published on June 27, 2003).

The disadvantages of the known traffic light are its low consumer properties and lack of reliability. The first is due to the fact that in the course of adjusting the movement, other colors can be used, in addition to those mentioned in the technical solution, and at the same time, for example, blue color, white color can be used. At the same time, to accommodate these colors, it is necessary to increase the overall dimensions of the traffic light, which entails, due to the possibility of placing the traffic light in an open area, an increase in the sailness of the structure with the traffic light, which increases the likelihood of its failure.

A traffic control device is also known - a traffic light, which includes two rotating disks, a vario-colored light source mounted behind the disks in the form of a cross, while, for example, there is a green stripe horizontally and red in a vertical direction (see UK Patent No. 297921, IPC G 08 G 1/09, publ. 04.10.1928).

A disadvantage of the known device is that it is difficult to use three or more colors in its operation, which reduces its consumer properties, while jamming the disks leads to the failure of the traffic light, which indicates its lack of reliability.

Known vario-color traffic lights, consisting of a housing with a board of LEDs, while on the same board alternately or in the form of symbols are LEDs

red, yellow and green colors or red and green colors, the traffic light has a multi-lens diffuser (see application for the grant of a patent of the Russian Federation for invention №2001114529, IPC F 21 V 13/00, publ. 10.06.2003).

However, the well-known technical solution is also inherent in low consumer properties and lack of reliability. In the process of operation, non-compactly located LEDs of the same color may not give a bright signal, which is necessary for an unambiguous interpretation of the traffic signal. This is due to the fact that a traffic light in an open area is more susceptible to natural factors, such as dust. Moreover, in some cases, the dustiness of the lens diffuser and the signal of insufficient brightness can lead to a situation in which it will be difficult to determine the traffic signal, which is equivalent to the failure of the traffic light. In addition, when using the known traffic light design, it is difficult to give bright directional signals of several colors at the same time.

Also known is a LED traffic light having a housing, wherein the LEDs of three colors are placed on the above housing, and the LEDs of each color form a symbolic image. The above LEDs are limited by contrasting LEDs arranged in a circle (see WIPO patent for invention No. 0031708, IPC G 08 G 1/095, publ. 02.06.2000).

However, the above design has a number of disadvantages. Firstly, with its help it is difficult to give bright directional signals, as well as signals of several colors at the same time. In addition, the number of colors used is limited to three. This reduces the consumer properties of a known traffic light. Secondly, the failure of several LEDs will distort the image, in fact lead to the failure of the traffic light, which may result in incorrect interpretation of traffic signals by traffic participants, which will increase the likelihood of an emergency.

Closest to the proposed technical solution is the well-known traffic light, comprising a housing, inside of which blue, yellow and red LEDs are placed on the board, while LEDs of the same color are placed in horizontally oriented rows. The total set of LEDs forms a geometric figure with convex lateral sides (see the application for a Japanese patent for invention No. 2001307294, IPC G 08 G 1/095, publ. 02.11.2002).

The known design has the following disadvantages. When automation fails, simultaneous operation of LEDs of various colors is possible, due to

of which there is an imposition of light waves and the resulting signal has a color different from the original one, however, allowed by traffic rules, which is impractical and prevents proper interpretation of the traffic signal from traffic participants. This reduces the consumer properties of the traffic light and indicates its lack of reliability.

The task to which the real utility model is aimed is to increase the reliability of the traffic light and its consumer properties.

The technical result achieved in solving the problem is to increase the intensity of a signal of one color and the exclusion of the addition of light waves of different lengths (colors).

The specified technical result is achieved by the fact that in the LED traffic light containing the housing, with LEDs of various colors placed inside it on the circuit board, according to the utility model, the LEDs are arranged in a circle divided into equal sectors, while the LEDs of the same color are grouped within one sector , the traffic light is equipped with a scattering lens, and between the circuit board and the lens there are made opaque partitions installed at the boundaries of the LED sectors.

The arrangement of the LEDs evenly around the circle, which is divided into equal sectors, allows you to reduce the overall dimensions of the traffic light, use several colors in the work of the traffic light to supply more signals. The arrangement of the LEDs in a circle is also advisable due to the following circumstances. Traffic lights available for use, as a rule, are equipped with scattering lenses in the form of a circle, which, therefore, will not lead to an increase in the cost of the new traffic light design when it is manufactured using a scattering lens. At the same time, traffic participants may not perceive a traffic light of a shape different from the circle when it is used as a traffic controller, which reduces the consumer properties of such traffic lights and will lead to an emergency.

The failure of several LEDs due to the grouping of LEDs of the same color will not distort the power of the light signal, which also increases the consumer properties of the traffic light. At the same time, the presence of a lens that simultaneously performs a protective function provides the possibility of operating traffic lights in any weather conditions, increasing reliability.

The presence of light-tight partitions between the board and the lens allows you to provide the most vivid intense color signal from the LEDs, which is necessary

for an unambiguous interpretation of the traffic light, even with dusty lens diffuser. In this case, it becomes possible to use bright traffic signals of several colors simultaneously with the help of a traffic light, excluding the addition of light waves of different lengths (which changes the color of the signal), and, thus, a false interpretation of the supplied signal.

The use of one LED head for different color indications of a traffic light allows to reduce the cost of a traffic light, simplify its operation and further reduce operating costs.

The utility model is illustrated by the following drawings, in which Fig. 1 schematically shows a traffic light housing, with LEDs placed inside it on the board, general view; figure 2 too, side view.

The positions in the drawings indicate the following: 1 - housing; 2 - LEDs; 3 - sectors; 4 - scattering lens; 5 - lightproof partition.

The LED traffic light contains a housing 1, inside of which LEDs of 2 different colors are placed on the board. The housing 1 during operation is installed on the mast-rack (not shown). The LEDs 2 are placed in a circle divided into equal sectors 3, for example, into four sectors. In this case, the LEDs 2 of the same color are grouped within the same sector 3 (figure 1).

The traffic light is equipped with a scattering lens 4. Between the circuit board and the lens 4 there are made opaque partitions 5, which are installed at the boundaries of the sectors 3 of the placement of the LEDs 2. An increase in the number of opaque partitions 5 makes it possible to install more LEDs 2 of different colors, increasing the number of combinations of traffic signals (Fig. 1 and 2).

The LEDs 2 can be powered from an alternating current source with a voltage of 12 V, a frequency of 50 Hz or a constant voltage of 12V.

As elements used in traffic lights, for example, LEDs of the L-1543 SRC-E type (manufacturer - "Kingbright Electronic Co., Ltd", Taiwan) can be taken.

LED traffic light works as follows.

The traffic light can be controlled by motherboards, also located in the housing 1, which automatically control the traffic light and are configured to supply signals of certain colors in traffic situations in accordance with existing rules and regulations for traffic regulation.

After applying power, for example, from an autonomous power source, the signal from the system board is fed to the LEDs 2 located on the board inside the housing 1

a traffic light, after which the LEDs 2 begin to emit a light wave of a certain length corresponding to the color of the signal, regulating or reporting the current traffic situation to traffic participants, for example, prohibiting or allowing traffic.

In this case, the LEDs 2 of the same color, grouped within the same sector 3, give a more powerful luminous flux (compared with the prototype).

Due to the location of the traffic light in an open space, the scattering lens 4 allows the light signal to be transmitted over a considerable distance without distortion, while protecting the LEDs 2 from external environmental influences. When applying signals containing several colors simultaneously, the opaque partitions 5 provide a clear light signal without the addition of light waves, which gives an unambiguous interpretation of the signal by the participants in the movement.

Thus, the proposed LED traffic light can be used in the organization of traffic, for example, railway, and has improved consumer properties and reliability, providing an increase in the intensity of a single color signal and eliminating the addition of light waves of different lengths (colors).
