BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic light, and more particularly, to a traffic light using a light emitting diode that enables a driver to more clearly recognize a signal provided from a traffic light.

In general, the control of the progress and direction of the vehicle has been made according to the flashing state of the traffic light, such a traffic light is currently used in consideration of the heat generation, power amount, life time is converted from the light bulb to the light emitting diode.

The conventional traffic light 100 is composed of a plurality of modules 110 required for the signal system, as shown in Figure 1, the module 110 is a monochromatic light emitting diode that emits a single color, that is, one color instead of the bulb 110 Has been installed, and the plurality of modules 110 are configured to display green, red, yellow, arrows, etc., which correspond to progress, stop, standby, direction indications, respectively.

However, the traffic light 100 equipped with a monochromatic light emitting diode required at least one module 110 to display red, green, yellow and arrows, respectively, for each color and shape required in the signal system. Since the number of light emitting diode modules 110 is required as many as the number of light bulb modules, a product purchase cost is increased, and the number of modules 110 that are turned on when a signal is transmitted is the same as when a light bulb is used. There was a problem that the shortcomings persisted.

The present invention devised in view of the above problems, since the multi-color light emitting die that can develop at least three colors in the module of the traffic light is mounted, it is possible to transmit all traffic signals to the minimum number of modules desired. In addition, traffic using light-emitting diodes, which can be lit up in a wide range of colors and shapes required according to the corresponding traffic signals, can reduce the accidents caused by unrecognized traffic signals by allowing drivers to recognize traffic signals more clearly. The purpose is to provide a traffic light.

For example, in the case of a single traffic signal such as driving, stopping, waiting, turning left, turning right, etc., a single indicating color and an indicating arrow indicating rotation are matched to all the modules 20 simultaneously. Lights up.

In addition, in the case of the simultaneous traffic signal including the left turn when the vehicle proceeds and the left turn when the vehicle is stopped, the indication color corresponding to the progress or the stop and the indication arrow required for the rotation are divided and lit by the left and right modules 20. do.

Meanwhile, FIG. 3 illustrates a second embodiment in which a single integrated module equipped with a multicolored light emitting diode is flickered according to a traffic signal, and includes an integrated module 30 including a plurality of modules (20 of FIG. 2). In the case of a single signal, one indicator color such as red, green, yellow, etc. lights up over the entire range of the light emitting module 30, and the direction indication arrows are divided into zones, and one or more lights simultaneously. In the case of the indicator color and the indicator arrow is divided by the zone of the module 30 is lit.

For example, an indication color of a selected one of green, red, or yellow lights up in the entire range of the module 30 in the case of progressing, stopping, or waiting for a single traffic signal of the vehicle, and indicating a direction in the case of left turn or right turn. One or more arrows illuminate at the same shape in module 30.

In addition, in the case of a simultaneous traffic signal including a left turn when the vehicle proceeds and a left turn when the vehicle is stopped, one indicator color corresponding to the progress or stop and one or more indicator arrows required for the rotation are divided in the module 30. Lights up.

For example, in the case of a single traffic signal such as driving, stopping, waiting, turning left or right of a vehicle, one indicating color corresponding to the signal and an indicating arrow indicating rotation are used for the monochromatic light emitting diode having the same color. Simultaneous lighting is indicated on each module 40.

In addition, in the case of a simultaneous traffic signal including a left turn when the vehicle proceeds and a left turn when the vehicle is stopped, a single color light emitting diode having the same color as one indication color corresponding to the progress or stop and the indication arrow required for rotation is simultaneously displayed. The display is divided into modules 40 by lighting.
