Description

The invention relates to road devices that form information and warning signals to alert road users to ensure that pedestrians cross the carriageway safely within the boundaries of a pedestrian crossing and can be used to organize traffic.

Information and warning devices are known in the art in the form of a pedestrian traffic light comprising a two-piece housing with a translucent protective screen fixedly mounted on it and internal light sources in the form of LED arrays mounted on printed circuit boards and equipped with an electronic control circuit, while the array of LEDs is placed in the upper section the red signal, assembled from the red LEDs of the glow, forming a stylized “standing man” figure, as well as the green LEDs lazy colors of glow, forming a digital indicator with a countdown of time in seconds, and in the lower section - a matrix of green LEDs, assembled from green LEDs of glow, forming a stylized “walking man” figure (see, for example: RF patent for invention изобретение 2266570 , IPC G08G 1/095, published on 12/20/2005; RF patent for useful model No. 87552, IPC G08G 1/095, published on 10.10.2009.

As a rule, well-known pedestrian traffic lights are installed on road traffic sections equipped with traffic lights, which alert vehicle drivers to the need to free the carriageway to move pedestrians in the area of the pedestrian crossing. However, due to various circumstances, for example, in conditions of poor or insufficient visibility of the traffic situation, the prohibiting signal of a traffic light can be ignored.

In this regard, the main disadvantage of the well-known pedestrian traffic lights is that they do not structurally provide for functional elements of the warning light of vehicle drivers about the situation in the zebra road marking zone as an additional informant, thereby not providing the maximum road safety. Thus, these information and warning devices are not sufficiently informative.

The disadvantages associated with the inability to illuminate the site along the direction of the pedestrian crossing, deprived of information-warning devices known from the prior art (see, for example: RF patent for useful model No. 92869, IPC E01F 9/06, publ. 04.04.2010; RF patent for utility model No. 117690, IPC G08G 1/095, published on 27.06.2012, RF patent for useful model No. 122795, IPC G08G 1/09, published on 10.12.2012), as well as information and warning devices (see, for example: RF patent for useful model No. 122514, IPC G08G 1/09, published on November 27, 2012; RF patent for useful model No. 123111, M PC F21S 8/00, published on 12/20/2012), containing LED lighting sources installed in the housing, which form the luminous flux to illuminate the road markings of the pedestrian crossing.

The above devices have a common drawback - the lack of functional elements related to the design of a pedestrian traffic light, which makes it impossible to notify pedestrians about the possibility of crossing the roadway. In this regard, the installation of such devices or systems is advisable only on the unloaded sections of the road, where there is no need to place traffic lights to adjust the movement of automotive vehicles. In addition, these devices do not provide the ability to adjust the angle of illumination along the direction of the pedestrian crossing, depending on the width of the carriageway. This generally reduces the technical capabilities of the known solutions and reduces their informativeness, without properly ensuring the safety of road traffic in the areas where such devices and systems are located.

Of the identified analogues, the roadside information and warning device according to the RF patent No. 2266570, made in the form of a pedestrian traffic light containing a two-section case with a fixedly fixed protective translucent screen and internal light sources installed on printed circuit boards and matrices of LEDs equipped with electronic control circuit, while in the upper section there is a matrix of LEDs assembled from red LEDs glow, forming a stylized figure of "standing man", as well as green LEDs glow, forming a digital indicator with a countdown of time in seconds, and in the lower section - a matrix of LEDs, assembled from green LEDs glow, made with the possibility of forming figures "walking man ".

The present invention is the creation of a combined road information and warning devices, providing:

- formation of prohibiting and enabling light signals of the pedestrian traffic light;

- adjustable by the angle of dispersion of the luminous flux, directed to the zone of the pedestrian crossing and providing illumination of the pedestrian marking along the entire width of the carriageway;

- the luminous flux directed to the pedestrian waiting area and providing illumination of the part of the sidewalk adjacent to the pedestrian crossing, located directly below the information and warning device.

In this case, according to the invention, the light source forming the luminous flux in the direction of the road marking zone of the pedestrian lighting transition can be made in the form of one or at least two LED luminaires mounted on the same horizontal level in the front surface of the lighting device. At the same time, the light source, which forms the luminous flux in the direction of the pedestrian waiting area, can be made in the form of an LED chip mounted on a printed circuit board (for example, SMD or COM) or at least two LED chips mounted on a printed circuit board and grouped into a set of lighting elements installed in series along the bottom surface of the housing.

This implementation allows in General to increase the information content of the proposed device by simplifying the mechanism of visual perception of the time interval remaining until the change of the light signal.
