Description

  The present invention relates to a traffic signal device.

  In conventional traffic lights, incandescent bulbs are lit by attaching a colored (red / yellow / green) lens-attached lid attached to the front of the lamp housing.

  At the intersection with opposite lanes, two signal lights for vehicles were mounted back to back using a mounting bracket on one signal pole.

  In recent years, LED signal lamps have been put into practical use in place of conventional incandescent bulb type signal lamps for the purpose of reducing power consumption and solving the problem of pseudo lighting due to the sun.

  As an LED signal lamp, a red LED, a yellow LED, and a green LED are used as light sources, and these LEDs are attached to a lens-attached lid attached to the front surface of the lamp housing. During maintenance, each lid is opened.

  As a result of replacing the LED signal lamp, we will review the cost of the signal lamp housing, consider installation methods, and work methods. For this purpose, it is necessary to light both sides of one signal lamp.

  At busy intersections, pedestrian traffic lights are installed opposite the intersection. It may be difficult for visually impaired people to see the opposite traffic lights.

  Therefore, in order to assist the crossing of visually impaired persons, a signal device with an audio device that emits a guide sound from a speaker arranged in the vicinity of the pedestrian signal lamp when it is possible to cross is installed. However, it is difficult to ensure the safety of crossing at night for visually handicapped people because it does not emit guidance sound at night in consideration of nearby residents.

  Conventional vehicle signal lamps are complicated in construction because two vehicle signal lamps are mounted back to back using a mounting bracket on one signal pole at an intersection with opposite lanes.

  For this reason, when two vehicle signal lamps are used, the signal lamp and the mounting hardware are very heavy, and a load is applied to the pillar.

  Is it possible to reduce costs by using a single signal lamp housing rather than using two conventional signal lamps? Here, the signal lamp is a vehicle signal lamp or a pedestrian signal lamp.

  Conventional signal lamps have light bulbs attached to each color and are connected by cables. Even after the use of LEDs in recent years, printed boards mounted with LEDs are attached to the lids of the red, yellow, and green housings and wired with cables. An LED is a light emitting diode. Is it possible to increase productivity by mounting each color LED on a single printed circuit board and attaching it to the housing, and reduce the number of cables in the housing to reduce costs?

  During maintenance, it was necessary to open the red, yellow, and green lids. Isn't it possible to improve work efficiency by reducing the number of printed circuit boards on which LEDs are mounted and using a single lid?

  Pedestrian signal lamps are installed at intersections where there are many traffics, but it may be difficult for visually handicapped people to check the opposite traffic lights. Not all intersections have voice guidance devices, and the volume of the voice guidance devices may be turned off at night. Is it easy to check the pedestrian signal light from the back?

  The direction that can be seen from the center of the intersection is called front, and the opposite is called back.

The invention of claim 1 comprises a printed circuit board in which an LED unit that lights up for the front and a printed circuit board that incorporates an LED unit that lights up in the back in one traffic signal lamp. It is a double-sided signal lamp.
An LED unit refers to an assembly of many LEDs.
Each printed circuit board is attached to the back of the lens cover of the housing and finished into one signal lamp. (Figure 1)
Connect the necessary connection cables between the printed circuit boards for each color, and perform the work for front and back.
These can also be applied to pedestrian signal lamps. (Fig. 5)

The invention of claim 2 is composed of a printed circuit board that is integrated by incorporating an LED unit that illuminates the front in one traffic signal lamp, and a printed circuit board that is integrated by incorporating an LED unit that illuminates the back. This is a double-sided signal lamp. (Figure 2)
In the case of a vehicle signal lamp, the red, yellow and green LED units that are lit for the front are attached to one board, and the red, yellow, and green LED units that are lit for the back are attached to one board. Attach to the vehicle signal lamp housing.
In the printed circuit board in which the LED units for the respective colors to be lit are integrated and integrated, the connection cable necessary between the printed circuit boards for each color as in the first aspect can be deleted. The cause of failure can be reduced by reducing the number of connection cables.
These can also be applied to signal lights for pedestrians, with red and green LED units that light up for the front mounted on one board, and red and green LED units that light up for the back mounted on one board. Attach to the pedestrian signal lamp housing. (Fig. 6)

The invention of claim 3 insulates the integrated printed circuit board by incorporating the LED unit that lights up for the front and the integrated printed circuit board that incorporates the LED unit that lights up for the back into one traffic signal lamp. It is a double-sided signal lamp configured so that the substrates do not come into contact with each other by being sandwiched between bodies. (Figure 3)
Examples of the insulator include a film or sheet such as rubber, plastic, and glass, a block, paper, and cloth. There are also oil-based films and paints. There is also a method of insulating by providing a space between the substrates.
These can also be applied to pedestrian signal lamps. (Fig. 7)

The invention of claim 4 is a double-sided signal lamp comprising a single printed circuit board in which a front LED chip and a back LED chip are mounted on a double-sided printed circuit board. (Fig. 4)
Here, the LED chip refers to an assembly of a number of LED chips.
These can also be applied to pedestrian signal lamps. (Fig. 8)

  In order to mount a printed circuit board incorporating an LED unit in a housing, the lid of the housing is opened downward to provide a single light. By using one lid, the housing is greatly opened, so it is easy to set an integrated printed circuit board that incorporates each LED unit to be lit. It is effective because only one sheet needs to be opened. (Fig. 9)

  In order to mount a printed circuit board in which an LED unit is incorporated in a housing, the lid of the housing opens sideways and is a signal lamp with a single lid. (Fig. 10)

  Conventional signal lamps were mounted with hardware, with two signal lamps back-to-back with respect to one signal pole at the intersection with the opposite lane. However, it is only necessary to mount one, so installation work is easy.

  When two signal lamps are used, the weight of the lamp itself is reduced by reducing it to one, the number of fittings can be reduced, and the load on the pillar is reduced.

  The cost can be reduced by using one conventional signal lamp as compared with the case where two signal lamps are used.

  By reducing the number of cables wired in the signal lamp, the cause of failure is reduced and costs can be reduced.

  Productivity is improved by inserting or mounting each color LED on a single board and attaching it to a housing.

  During maintenance, it was necessary to open the red, yellow, and green lids, but by reducing the number of LEDs mounted on the board to one, the lid can be made one, increasing work efficiency. .

  The signal lamps attached back to back are thin and small.

  Because visually impaired persons can see a pedestrian signal lamp in the immediate vicinity, they can safely cross the road.
