Abstract

The present invention relates to a traffic light, and more specifically, to a traffic light for a vehicle or a pedestrian, using a multi-color LED, unlike a conventional traffic light composed of three or two lights such as red, yellow, green or red, green, etc. It relates to a variable traffic signal which makes it possible to display red, yellow, green and green arrows if necessary in a sphere consisting of

In addition, the present invention is characterized by controlling each of the plurality of LED, so that the remaining time of the traffic light.

Description

Variable traffic light {The changeable traffic light}

The present invention relates to a traffic light, and more particularly, to a variable traffic light that displays various signals such as red, yellow, and green in one sphere using multi-color LEDs capable of displaying a plurality of colors. Furthermore, it is characterized by controlling a plurality of LEDs, so as to know the remaining time of the traffic light.

The present invention is different from the existing traffic light is different from the existing traffic lights consisting of 2 to 4 spheres by displaying all the information in one, the configuration is simple and can recognize the traffic lights more easily, a separate remaining time indicator It is possible to provide the remaining time information of the corresponding signal even if not.

Traffic lights are classified into vehicle lights, pedestrian lights, bicycle lights, etc., depending on the purpose, and are classified into bulb type and LED type according to the devices used.

In the case of vehicle lights, two-color auxiliary lights consisting of red and green lights, three-color lights consisting of red, yellow, and green, red, yellow, green arrows, four-color lights consisting of green, red X marks, and variable lights consisting of green arrows have. In the case of pedestrian lights, there are two-color lights consisting of a human stop-shaped red light and a human walking green light. Bicycle lights include two colors red and green, three colors red, yellow and green.

In the case of the bulb type traffic light, the bulb is used as a light source, and the lens of the lamp is used to display the signal of the appropriate color using the required colors such as red, yellow, and green.The LED type traffic light uses red, yellow, and green LEDs, respectively. Display a signal of the appropriate color, and the lens uses colorless. The difference between the light bulb and the LED signal is that the bulb needs to be replaced once every 3 to 4 months, and there is a lot of heat and relatively high energy consumption.However, if the LED signal is installed once, it is semi-permanent without replacement. It can be used and relatively low energy consumption.

However, in the case of LED devices, without considering that one device can display multiple primary colors, currently used LED signal lamps made of the same mechanism as existing bulb signals are complicated in configuration and the degree of recognition of signals It has a limitation that can be comparable to the global traffic lights.

In particular, when the lighting effect is lowered by sunlight or the like, there is a problem that it is difficult to recognize the lit signal in the existing signal lamps that are always displayed red, yellow, green.

The present invention was created in order to solve the above problems, and simplifies the configuration of the traffic light to one ball, and the variable traffic to inform the remaining time information of the required traffic signal and the corresponding traffic signal, such as red, yellow, green in one ball The purpose is to provide a traffic light.

Multi-color LEDs can be used to display multiple colors such as red, yellow, and green on a single LED. It is characterized by providing time information.

Traffic light according to the present invention as described above can display a plurality of colors, such as red, yellow, green in one sphere using a multi-color LED can simplify the configuration of the traffic light, the driver or pedestrian You can see only one color that is lit so that you can easily recognize the signal that corresponds to you.

In particular, it is possible to control each of the plurality of LED elements can be enough to recognize the remaining time as the number of LED elements are turned on.

In addition, if necessary, bicycle lights can be displayed in red or green in the shape of bicycles, pedestrian stops in red, or green in the shape of pedestrians walking. One traffic light display can be used for various traffic lights.

The variable traffic light of the present invention for achieving the above object is composed of a plurality of multi-color LED as shown in FIG.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a traffic light composed of a plurality of spheres in accordance with a signal indicating that the traffic light for the existing vehicle.

Figure 2 shows a signal display of the traffic light for the existing vehicle shown in FIG. a represents a red signal, b represents a yellow signal, c represents a left turn signal, and d represents a green signal.

Figure 3 shows a traffic route composed of one sphere in accordance with an embodiment of the present invention.

4 shows a signal display and a remaining time display of a traffic light according to the embodiment of the present invention shown in FIG. a is all LEDs light up red or green immediately after the red or green signal is received. b indicates that some LED in the center is turned off when the remaining time of the red or green signal is about half as time passes. c is the remaining time of the signal, and only the LED of the outer frame is turned on.

5 shows the same embodiment as in FIG. 4, but the LED is turned off from the top to the bottom while the remaining time is left to go from the center to the outside. As in FIG. 4, a is shortly after the red or green signal is input, and b is when the remaining time of the red or green signal is about half remaining as time passes, and c is when the remaining time of the corresponding signal is short.

Figure 6 shows an embodiment of the present invention consisting of two spheres when there is a sin rotation signal.

7 illustrates an embodiment of the present invention when a left turn and a right turn signal are required.

8 shows an embodiment of the present invention when the signal is different depending on the lanes such as the section of the central bus lane.

Although the present invention has been described in detail by way of examples, the present invention is not necessarily limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention.
