Description

December 3, 2014), selected as a prototype, is disclosed that the traffic light comprises a vertical post, a transverse bar, a first block of signal lamps and an LED strip. The first block of signal lamps is a three-color signal lamp. The LED strip contains a group of three-color LEDs corresponding in color to the colors of the first block of signal lamps. The first block of warning lights is attached to the cross member. The LED strip is attached to the front of the upright in the vertical direction. The LED strip and the first block of signal lamps are connected to the same external signal control source, so that the first block of signal lamps and the LED strip can simultaneously emit red, orange or green signals. Thus, the area of the light signal of the traffic light increases, and therefore, the driver of the vehicle can distinguish signals at a greater distance.

The claimed solution uses an array of LEDs on a heat-removing base, which allows the use of more powerful LEDs.

A brief description of the drawings.

FIG. 1 shows schematically one embodiment of a traffic light with additional LED signaling.

Implementation of a utility model.

The standard traffic light is a substantially vertical part 1 (Fig. 1) of a traffic light (rack or pole) on which the main signaling unit 2 (Fig. 1) is installed, currently most often based on LEDs, although the light source can be not only LEDs, but any other light sources powered by electricity. Block 2 of the main signaling of a traffic light usually contains sections of three colors: red, orange and green. Block 2 of the main signaling of pedestrian and railway traffic lights usually contains sections of two colors: red and green.

In one embodiment, the proposed traffic light is the traffic light described above, on which an additional LED signaling unit 4 is mounted (FIG. 1), which duplicates the signals of the main traffic light signaling unit 2, so that drivers and pedestrians can see traffic light signals from a larger distance.

This block 4 of additional LED signaling can be installed both on the vertical part 1 of the traffic light and on the inclined part 3 (Fig. 1) of the traffic light, as well as on both parts of the traffic light. The inclined part 3 can be fixed on the vertical part 1 of the traffic light at any angle and at any height, based on the road conditions in which the traffic light is located.

Block 4 of additional LED signaling is implemented on the basis of LEDs, preferably mounted on boards with an aluminum base, which provides heat dissipation from the LEDs heating up during operation.

The base can also be textolite, provided that sufficient heat dissipation is provided by the textolite base, that is, when choosing diodes of the corresponding power. The aluminum base provides a high value of heat dissipation from the LEDs that heat up during operation and thereby allows the use of high power LEDs, which improves the visibility of the traffic light. The thickness of the board with an aluminum base is from 0.8 mm, with LED power up to 5 watts. When using a thicker base or using additional fins to remove heat, the maximum power of the LEDs used can be increased. The thickness of the board with a textolite base is from 0.8 mm, with LED power up to 3 W

The power supply unit 4 additional LED alarm is carried out by a separate power supply, that is, regardless of the power supply unit 2 of the main signaling of the traffic light, which ensures high reliability of the traffic light. In this case, the control of the additional and main alarms is carried out by one control unit, which ensures the synchronization of the inclusion of traffic signals.

The execution of an additional LED signaling in a polycarbonate profile provides high strength and structural rigidity, which allows it to be conveniently and quickly mounted at a traffic light. Fastening can only be done at two points for each polycarbonate profile. The process of mounting a rigid polycarbonate profile on the rectilinear surface of traffic lights is in itself simpler than, for example, mounting an LED strip, which can easily be damaged by mechanical stress.

If block 4 of additional LED signaling is installed on both the vertical and inclined parts of the traffic light, then it is made of two sections, each of which is placed in its polycarbonate profile and is fixed on the vertical and inclined parts of the traffic light. It is also possible that the sections are divided into several sections, if this simplifies the installation of additional LED indicators at the traffic light.

The design of the polycarbonate profile in one embodiment is self-supporting, which makes it possible to fix it without additional rigid support. The rigid construction of the additional LED signaling in the polycarbonate profile simplifies the installation of this alarm, since it can be fixed at the traffic light at only two points.

The polycarbonate profile in one embodiment is made in the form of a tube, the tube in cross section being a circle, square or rectangle. The presence of LEDs creates the effect of a luminous tube for an external observer. The tube uses diffusers to ensure its uniform glow. The stiffness of the polycarbonate profile simplifies the installation of diffusers in comparison with a flexible LED strip in a shell, for example, made of silicone.

In one embodiment, a tube is used for each of the three colors of traffic signals, which is more convenient when servicing a traffic light. In case of failure of the LEDs responsible for any one color, you can replace the tube only with this color.

In one embodiment, three subarrays of LEDs are used to create an alarm of the desired color: red, orange, and green. Each mixture is connected to the control unit and turns on synchronously with the signals of block 2 of the main traffic light signal.

In another embodiment, to create the signal of the desired color, mixing of different colors of the visible spectrum is used so as to obtain red, yellow and green traffic signals. In this embodiment, the traffic light control unit is connected to the controller of the additional LED signaling unit 4, which provides mixing of different colors to obtain a red, orange or green signal specified by the traffic light control unit.

The work of the proposed traffic light is as follows.

Block 2 of the main signaling receives a signal about which light signal should be turned on (red, orange, green), at the same time the same signal is also fed to the input of block 4 of additional LED signaling. Block 4 additional LED alarm provides the inclusion of a light signal of a given color essentially simultaneously with the signal of block 2 of the main alarm.

If the light signaling of block 4 is formed by mixing colors, then the controller of block 4 generates control signals in order to form the desired color of the light signaling of the traffic light by mixing. The technology for the formation of a given color by mixing colors is well known in the prior art and is not related to the essence of the claimed solution, therefore, is not described in detail here.

The signal about which light signal should be turned on comes either from the traffic light control module or from the centralized traffic control module. The traffic light control module can be a timer that sets the luminous time of each traffic light, the control module can be connected to the centralized traffic control module via wired or wireless communication lines and set the time of operation of a traffic light signal depending on the commands of the centralized module.

The presence of separate power supplies for the primary and secondary signaling can improve the reliability of the traffic light. The parameters of the power supply unit 4 of additional LED signaling are selected based on the power consumed by the LEDs required for the operation of the voltage LEDs. In addition, for each individual color of the additional LED signaling, its own power supply is used, which receives signals from the main signaling unit 2, which avoids the use of a switch, which would be necessary if one power supply were used, which increases the functionality of using the additional signaling.
