Description

Technical Field

[0001] This invention relates to an upper-level wire harness illumination type ground traffic light, and more specifically, to an upper-level wire harness illumination type ground traffic light that installs a wire harness illumination component on a traffic light bracket equipped with pedestrian or vehicle traffic lights, thereby saving engineering costs and facilitating maintenance and management. Background Technology

[0002] Generally speaking, zebra crossings are pedestrian facilities with safety signs on the road, allowing pedestrians to cross the road. These zebra crossings are equipped with vehicle traffic lights and pedestrian traffic lights to prevent collisions with cars.

[0003] In addition, the traffic lights mentioned above are set at both ends of the zebra crossing as one of the traffic safety measures to guide pedestrians to cross the zebra crossing by using red and green lights. They guide pedestrians not to enter the zebra crossing when the light is red, but only when the light is green.

[0004] Recently, with the increase in smartphone use, there has also been an increase in people looking down at their smartphone screens. These people are called "Smombies" (Smartphone Zombie). Smombie, for example, did not check the traffic light signal when crossing a zebra crossing, potentially causing a traffic accident.

[0005] As a preliminary technology for solving the above problems, Korean Patent Registration No. 10-1905794 registered a ground traffic light with linkage control on a pedestrian crossing signal light. This preliminary technology involves a rectangular light-emitting box with openings at the top, sides, and bottom. An LED lighting substrate is inserted and installed inside the upper part of the light-emitting box to illuminate the upper part of the box. A cardboard support block is inserted and installed below the LED lighting substrate inside the light-emitting box to support it. The LED lighting substrate is installed between the substrate support block and the substrate inside the light-emitting box to prevent the upper part of the light-emitting box from bearing weight. The LED lighting substrate is inserted from the bottom of the light-emitting box. The base block supporting the light-emitting shell, the light-emitting shell, the LED lighting substrate, and the substrate support block are combined together, including measures to prevent moisture penetration into the LED lighting substrate. The epoxy resin of the board is located between the top of the inner surface of the light-emitting shell and the top of the LED lighting substrate, between the bottom of the LED lighting substrate and the top of the substrate support block, between the front of the substrate support block and the front surface of the inner surface of the light-emitting shell, between the back of the substrate support block and the back surface of the inner surface of the light-emitting shell, and at the bottom of the substrate support block. Double-protrusion outlets for contacting the upper cross-section of the inner surface of the light-emitting shell are provided at the front and rear of the top of the substrate support block. Each protrusion is inserted into a substrate protrusion on the inner side of the protrusion outlet. Multiple protrusions are formed on the top of the substrate support plate and both sides of the substrate support block, and multiple protrusions are formed between the bottom of the substrate support plate and the substrate protrusions. The light irradiated on the LED lighting substrate can easily confirm the signal of the indicator light.

[0006] However, the aforementioned advanced technologies increase the purchase cost of LED lighting substrates, which need to be buried near zebra crossing boundary stones, increasing engineering costs and creating difficulties in maintenance and management.
