Abstract

The utility model relates to technical means for organizing traffic on roads and can be used in illuminated road signs. The road sign comprises a housing (1), a translucent panel (2) with the graphic image of the sign made from a light-reflective material (3), a light emitting diode source of internal illumination (4), a power supply (6), and an electric circuit for supplying power to the source of internal illumination (4) with a device for regulating light emission in the form of a photorelay (7). In order for the light emitting diode source of internal illumination (4) to be able to operate in a flashing mode, the electric circuit is additionally provided with a proximity sensor (9) and a controllable switching unit (10) for the supply current of the light emitting diodes (4). The technical result is an increase in road safety because of the attention of road users being attracted by the road sign operating in flashing mode, and a concomitant reduction in energy consumption when the article is operating in flashing mode.

Description

Road sign

Field of Technology:

The utility model relates to technical means of organizing traffic during the operation of roads and can be used in traffic signs with internal lighting.

The prior art:

There is a known road sign (see application for utility model NQ 2011137974, filing date 2011.09.15), which contains a housing, a translucent panel installed in the housing with a graphic image of the sign on the front side and geometric corrugation on the rear surface, an LED internal light source, an electrical power source and an electrical circuit for supplying power to the source of internal illumination. A reflective coating is applied to the inner surface of the housing and to the front surface of the translucent panel. A graphic image of the sign of reflective material is made in the center of the translucent panel on a reflective coating. To control the operating modes of the source of internal illumination, an additional photo relay connected to the power supply is installed in the electric circuit. The front surface of the translucent panel is covered with a protective glass.

However, there may be situations on the road, especially in the dark, when the driver does not notice a traffic sign and a pedestrian, for example, crossing a road along a “zebra,” which can lead to a traffic accident. Disclosure of utility model:

The task to which the claimed utility model is directed is to improve the operational characteristics of the product that ensure road safety.

The technical result of this utility model is to attract the attention of traffic participants to a road sign that is operating in a blinking mode with reduced power consumption.

To achieve the specified technical result in a traffic sign device comprising a housing, a light-permeable panel with a graphic representation of a sign made of reflective material, an LED internal illumination source, an electrical power source and an electric power supply circuit to the internal illumination source, comprising a light emission control device in the form of a light relay,

- for the flashing mode of operation of the LED source of internal illumination, the presence sensor and an adjustable power switching unit for the power supply of the LED source of internal illumination are additionally introduced into the electric circuit, which are installed in series with the power supply.

The presence sensor introduced into the electric circuit and the adjustable power supply switching unit of the LED internal illumination source allow the traffic sign to provide a blinking LED light source when approaching the traffic sign of a pedestrian crossing the road. Thus, drivers receive additional information about the presence of a pedestrian on the road. At the same time, the blinking operating mode LED backlit road sign reduces power consumption of the product.

Brief Description of the Drawings:

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

- in FIG. 1 shows a left side view of a road sign in section;

- in FIG. 2 - electrical unit - diagram of a road sign.

An embodiment of the invention:

The road sign contains a housing 1 (Fig. 1), in which a translucent panel 2 is installed. On the front surface of the translucent panel 2, a white reflective film 3 is applied with a graphic representation of a road sign of reflective material in the center (not shown). On the back surface of the translucent panel 2, a geometric corrugation (not shown) is made with a predetermined pitch and depth. The source of internal illumination is made in the form of an LED circuit 4 and is mounted on a sealed frame 5 so that the light flux is directed to the ends of the translucent panel 2. The LED circuit 4 is connected through an electric circuit and a light control device made in the form of a photorelay 7 to a power supply 6 A change in the brightness of the glow of a traffic sign is carried out using a photorelay 7 by changing the supply current depending on the general illumination of the place where the traffic sign is installed. For the flashing mode of operation of the LED circuit 4, an presence sensor 9 and an adjustable switching unit 10 supply current of the LED circuit 4 are additionally introduced into the electrical circuit. A mirror reflective coating is applied on the inner surface of the housing 1 8. Facial the surface of the translucent panel 2 with a graphic image of a road sign is covered with a protective glass.

The device operates as follows.

The operation of the power supply 6 of the LED circuit 4 is controlled by a photo relay 7. In the daytime, the source of internal illumination is turned off. When reducing the amount of environmental illumination from the photorelay 7 to the power supply 6, a signal is received to turn on the LED circuit 4 of the internal illumination. The radiation from the LEDs through the end surface is introduced into the transparent translucent panel 2, propagates along the panel 2, is reflected from the mirror coating 8 of the housing 1 and the rear surface with geometrical corrugation, passes through a reflective coating (film) 3 with a graphic image of a road sign, thus increasing , brightness of the highlighting of a graphic image of a road sign. When a pedestrian approaches a traffic sign, the presence detector 9 is activated, the blinking mode of the LED circuit 4 is turned on using the switching unit 10. This mode of operation attracts the attention of drivers, thereby increasing traffic safety and providing energy savings.

The proposed technical solution provides regulatory optical characteristics of the road sign under various operating conditions. Products using this technical solution are economical, easy to maintain, and have an extended service life. The reliability and efficiency of traffic management is enhanced.
