Description

A traffic signal for a walker

The present invention relates to a traffic light for pedestrians using a light emitting diode (LED) as a light source, and more specifically, using a discolored LED that is lit in green or red to shape the head and torso of the human body and walking legs. Green LED is used for shaping of the bridge, and red LED is used for shaping of the suspended bridge, so that both walking and stop markings can be realized on a single focusing board, and the green LED shows walking or stopping time at the bottom. And it relates to a pedestrian traffic light of the structure that can be displayed by the red LED to facilitate the convenience of the pedestrian (or waiting).

In general, traffic lights installed at the crossings have been replaced by structures that use high-brightness LEDs instead of the existing structures.

LEDs are arranged on the substrate and lighted up. In the existing lamp structure, if the lamp is not turned on due to damage or failure of the lamp, the entire function of the signal lamp is paralyzed. There is an advantage that the display function has little effect.

In such a traffic light having a structure using a conventional LED is a structure formed by arranging the green and red LEDs in the shape of the human body walking and the shape of the human body up and down. In addition, there is also a time display structure in which LEDs are arranged in the form of numbers to display walking time or stopping (or waiting time) time.

Such a conventional structure of the traffic light, as shown in Figure 1, the stop display unit 10 composed of a red LED 41 at the top, the walk display unit 20 composed of a green LED 42 below, and the top The red LED 41 and the green LED 42 are composed of a time display unit 30 in which a mixture is arranged below.

The stop display unit 10 is formed by using a plurality of red LEDs 41 in a standing position in a stationary state of a human body, and is for visually displaying a current stop (or standby).

The walking display unit 20 is a shape of a human body walking using a plurality of green LEDs 42 and is for visually displaying that walking is possible. The stop display unit 10 and the walk display unit 20 individually configure the shape of the human body during stop or walk using the red LED 41 and the green LED 42.

However, the time display unit 30 positioned below the red LED 41 and the green LED 42 has a structure arranged by mixing. For example, the white unit '1' and the ten unit two digits are displayed by mixing the red LEDs 41 and the green LEDs 42 in the form of seven segments, for displaying the time within a hundred units. If the stop display unit 10 is turned on, the time display unit 30 displays the time by turning on the red LED 41 of the mixed arrangement, and if the walk display unit 20 is lit, the time display unit 30 turns green. LED 42 lights up to indicate the time.

However, the conventional traffic light has a problem in that the structure of the walking state of the human body and the shape of the stationary state is separately formed as described above. Each of the LEDs 41 and 42 used in a traffic light has a high brightness structure, and thus requires a larger power consumption than a general low brightness LED. Therefore, when disposed separately as described above will cause a significant waste of power consumption.

In addition, this increases the overall volume and weight, and wastes time and manpower in the manufacture and installation. have.

Despite the fact that the color changing color of green or red color is already on the market, it is a waste of power consumption and installation as the human body shape is separately configured as the above-described LED (41,42) having a separate color. And it has the disadvantages such as the difficulty of manufacturing and the complexity of the electrical equipment.

And when the conventional traffic lights are installed at a long distance and used for a long time, the surface of each LED (41, 42) is stained with dirt, such as dirt. In this case, the brightness is low during lighting, making it difficult to visually identify the pedestrian, especially at night or when the weather is impure.

Although a cover structure is provided on the front of the traffic light to prevent contaminants, the dust and the smoke of the car are very fine, so they penetrate into the interior of the traffic light and cover the surfaces of the LEDs 41 and 42. Pollution will eventually serve as a serious problem causing traffic accidents at pedestrian crossings.

The present invention is conceived in view of the above-described conventional problems, the first object of the present invention is to change the green or red color of the structure that can be turned on by changing the shape of the head and body parts of the human body, It is to provide a pedestrian traffic light having a structure capable of constructing a traffic light as the number of LEDs.

A second object of the present invention is to provide a pedestrian traffic light having a structure in which the LED of the structure in which the antifouling layer is formed on the surface by UV coating is adopted.
