Abstract

PROBLEM TO BE SOLVED: To solve the problems in which: a lighting display unit with red, yellow, and green (blue) of a conventional traffic light is a three-lamp three color light emission type, and the diameter of one light emission lamp is small, which makes it likely to cause an error in seeing a signal due to backlight, street light, and other lighting, and a risk of the occurrence of an accident is large; the entire structure of the lighting display unit is large and imposes a heavy weight load on a pole or the like when it is attached, and is weak against strong wind.SOLUTION: Lighting display of a traffic light is performed by one lamp which performs signal display of red, yellow, and green, and the size (diameter) of one lamp is increased by about 30% of a conventional one light emission lamp to make it large and easy to see. Because of it, accidents in the vicinity of intersections have reduced dramatically. In addition, because of one lamp, labor to attach the traffic light to a pole or the like is simplified and the traffic light becomes strong against strong wind or the like.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a traffic signal device that displays red, yellow, and green (blue) lights at general road intersections and the like.

  The lighting display part of a conventional traffic signal is a three-color three-lamp type.

Problems to be solved by the invention

  As described above, the conventional traffic signal device has a three-lamp type lighting display, and each lighting display lamp is small and easily confused with backlight, street light, various lighting, etc., and there is a great risk of occurrence of an accident.

  In addition, the overall outer shape of the three-lamp display portion is large, such as horizontally long, and there is a drawback that the power pole and the mounting column are burdened with weight and weak against strong winds.

Means for solving the problem

  In order to solve the above-described problems, the present invention is to display a large number of three colors of red, yellow, and green (blue) with a single lighting display.

  As shown in FIG. 1, multiple color light emitting LEDs are assembled and arranged in one lamp, and the three colors of yellow are controlled and lit by simultaneous emission of red, green and red green. (In this case, explanation of the detailed control of the LED is omitted, but in order to balance the luminance of the three colors, voltage adjustment and single color LED may be appropriately arranged).

  In terms of cost, red, yellow, and green monochromatic LEDs may be alternately arranged in one lamp.

Effect of the invention

  The traffic light of the present invention, such as the conventional three-lamp type three-color lighting display unit, displays the three-color lighting with a single lamp and increases the outer diameter, making it easier for drivers and pedestrians to see and traffic at intersections It became useful for accident prevention.

  In addition, since the lighting display section is made one lamp, the entire structure of the display lamp section becomes compact, the weight burden on the power pole and the mounting post can be reduced, and the durability is strong against strong winds and the like.

BEST MODE FOR CARRYING OUT THE INVENTION

    Embodiments of the present invention will be described with reference to the drawings.

    1 is a front view in which the traffic light indicator lamp part is one lamp, the outer diameter is about 30% larger than that of the conventional product, and the LEDs are arranged together. 1 is a mounting plate, 2 is a lighting indicator lamp, 3 is an LED It is a collective arrangement.

    FIG. 2 is a schematic side view of a structure of a lamp using a multi-color light emitting LED for one dot body 4, in which red LED chips 5 and green LED chips 6 emitting different colors are arranged. In the case of a red signal, a red LED is used. In the case of a green signal, a green LED chip for a green signal. In the case of a yellow signal, a red LED chip and a green LED chip are respectively light-emitting multiple-color light emitting LED lamps that simultaneously apply and emit light.

    Fig. 3 is a front view of the conventional lighting indicator lamps such as LEDs of traffic signals. The three-lamp type of single color lighting of red, yellow and green is made smaller in the outer diameter of the single color lamp. The entire structure of the indicator lamp is large, such as horizontally long.
