Description

TRAFFIC SIGNAL LAMP FOR INSTALLING ON CROSSWALK}

The present invention relates to a traffic light installed on a pedestrian crossing used for pedestrian and transporter assistance, and more specifically, it is used in six and consists of three pedestrian traffic lights and three vehicle auxiliary traffic lights. It has been reduced to three, and it can be used to inform the remaining time of each traffic light or to make pedestrians and drivers focus more on the traffic lights through the blinking signal, which can drastically reduce the traffic accidents occurring in the crosswalk. It relates to a traffic light installed.

In general, traffic lights are used to indicate traffic conditions in color for safe traffic order. There are three colors, red, green, and orange, and red lights (hereinafter, "red lights"). ) Is a stop signal, green light (hereinafter referred to as "green light") is a progress signal, orange light is indicated as a caution, but road traffic means yellow (hereinafter referred to as "yellow light") means to bypass. Also used.

Such traffic lights are roughly classified into traffic lights using halogen lamps and traffic lights using light emitting diodes.

Among them, a reflector was installed at the rear of a halogen lamp as a light source, and a diffuser lens was installed at the front to diffuse light in various directions to reduce glare caused by the concentration of light.

In addition, a light shielding shade is installed above the diffusion lens to prevent sunlight from being reflected by a reflector installed therein, which makes it difficult to determine which signal light is turned on (phantom effect). It was supposed to prevent.

However, the conventional traffic light using such a halogen lamp has a problem that the surface of the diffusing lens should be cleaned regularly because of the shading shade cannot be expected to be natural, and therefore the maintenance cost for cleaning It was necessary. That is, on the road, tire dust generated by the friction between the tire and the road surface, carbides generated from the exhaust gas, and various dusts blown while driving the vehicle are adsorbed onto the surface of the diffusion lens, thereby reducing the transmittance of light. It can maintain the required light transmittance only by cleaning artificially or naturally, but in the past, the shading shade positioned above the diffusing lens blocks the rainwater, so natural washing could not be expected. There was a closure where the surface was stained.

In addition, even when the shading shade is installed, when the sunlight rays are shining toward the front of the traffic light, the faint phenomena, which are difficult to distinguish from the lit traffic light, are still generated because the light is transmitted inside and reflected by the reflector. .

Therefore, the shading shade must be installed for a longer time, and the long shading shade has a problem of lowering the recognition rate by blocking the light spreading to the side as well as blocking the light of the traffic light.

In addition, the lifespan of a signal lamp using a halogen lamp is very short, such as 5 months, which leads to a problem of high maintenance costs.In order to light a halogen lamp, a large current and a large voltage power supply are required. There was a problem of a possible safety accident.

On the other hand, in the case of a traffic light using a light emitting diode (LED), a large number of high brightness light emitting diodes are arranged on a printed circuit board at narrow intervals, and each light emitting diode has a current limiting resistor connected thereto. In front of it was a transparent protective cover.

However, the conventional traffic light using such a light emitting diode also needs a shading shade like a traffic light using a halogen lamp, so natural cleaning by rainwater cannot be expected. Therefore, the surface of the transparent protective cover must be periodically cleaned. This required a maintenance fee for cleaning.

In addition, a signal lamp using a light emitting diode has a problem in that a plurality of light emitting diodes are arranged on a printed circuit board and a current limiting resistor is connected to each light emitting diode, so that the failure rate is high.

Conventional power consumption of the signal lamp using a halogen lamp is about 100 watts (W), the signal lamp using a light emitting diode has a problem that the power consumption is large because the power consumption is about 20 watts (W).

On the other hand, traffic lights using such light emitting diodes or halogen lamps are all managed in the order set mechanically by the traffic control system. That is, people crossing the crosswalk have a problem of causing a crosswalk accident because it is difficult to predict the time at which the signal is changed.

The present invention consists of three traffic lights including two pedestrian traffic lights and one vehicle auxiliary traffic light. Each of the two pedestrian traffic lights has a number indicating the time when the red light at the top is turned off. In the reverse order, the red light turns off when it becomes '0', followed by the green light at the bottom, and the number indicating the time when the green light is turned off at the top is displayed in the reverse order, and the red light turns on when it becomes '0'. The purpose is to provide traffic lights installed on the sidewalk.

Another object of the present invention is that the vehicle auxiliary signal light is shown in four states, the four state is a blue light, the Arabian time indicator indicating the time when the blue turns off, the red light and red light flashing signal to the progress or standby signal of the vehicle The purpose is to provide traffic lights installed on the crosswalk configured to be represented according to.

This is to ventilate the pedestrian's surroundings, and also to avoid misunderstanding by the green signal.

On the contrary, when the control unit 130 displays the green light on the lower traffic light 150, the upper signal light 150 receives the time during which the green light is displayed from the green light timer 114, which is a 2-digit number. Display in the form of. In this case, when the green signal is preferably displayed on the lower traffic light 150, it is preferable to display the time when the green signal of the lower traffic light 150 remains using the green LED of the upper traffic light 140. This is to ventilate the circumference of the pedestrian and to prevent the pedestrian from crossing the road due to mistaken red signal.

Meanwhile, when the green light is displayed on the lower traffic light 150, the controller 130 implements a red signal on the vehicle auxiliary traffic light 160. For reference, since the green indicator of the lower traffic light 150 and the vehicle auxiliary signal light 160 are safe to give a little clearance, the lighting time of the lower signal light 150 and the lighting time of the vehicle auxiliary signal light 160 are slightly different. There can be. Still, the walking traffic lights 140 and 150 and the vehicle auxiliary traffic light 160 operate in conjunction with each other. The vehicle auxiliary signal light 160 is displayed in red when the pedestrian signal is green when the pedestrian signal is green in association with the pedestrian traffic lights 140 and 150. Under the control of the LED light amount adjusting unit 160 5 seconds before the vehicle progress signal, the strong flashing signal flashes 5 times at 1 second intervals, and then changes to a green signal to provide information to the driver in advance.

In addition, during the implementation of the green signal, which is the vehicle progress signal, the remaining time of the vehicle progress signal is displayed in Arabic numerals in the order of 5-> 4-> 3-> 2-> 1-> 0 from the moment the remaining time of the vehicle progress signal remains 5 seconds. By displaying, the driver recognizes the remaining time in advance and recognizes the progress time of the car so that the driver can recognize the time when the pedestrian crosses through the crosswalk to prevent accidents.

In addition, the upper signal light 140, the lower signal light 150, and the vehicle auxiliary signal light 160 all have red high brightness LEDs and green high brightness LEDs in the same ratio so as to realize red and green lights. It is a traffic light implemented to emit a desired color.
