JP7401055B2 - Flaming tube alternative light-emitting device - Google Patents

Description

The present invention relates to an alternative light-emitting device for a flare tube, and more particularly to a substitute light-emitting device for a flare tube, which is installed on the road surface of a highway or the like and is used as a substitute for a flare tube to alert drivers of vehicles traveling on the road.

On roads such as expressways, for example, when dealing with the aftermath of a traffic accident, or carrying out road repair work or cleaning work, drivers of moving vehicles are given information after these accidents. As a way to draw attention to the fact that treatment or repair work is being carried out, patrol members, preferably riding in work vehicles called yellow patrols for road work, set up flares on the road surface to call attention to the situation. method is commonly adopted. In order to ensure the safety of moving vehicles, multiple flares are installed at predetermined intervals in a section several hundred meters to several kilometers in front of an accident site or work site. It has a function that not only alerts moving vehicles of danger, but also warns them in advance so that they do not enter accident sites or work sites.

In addition, the flare can be ignited in one action, for example by twisting and pulling the cap, so that a patrolman riding in a work vehicle can ignite it quickly and set it on the road surface. For example, in order to make the light from a flame visible from more than 600 m away during the day and more than 2 km away at night, it is preferable to ensure a luminous intensity of 200 candela or more, and for example, the wind speed is about 18 m/sec and the amount of rain is low. Efforts have been made to enable normal combustion even in environments with speeds of about 50 mm/h.

Furthermore, flare tubes can roll or shift sideways due to gusts of wind, etc., and there is a risk of roadside fires due to the ignited flames. For example, if gasoline or oil is leaking at the scene of an accident, it may become unusable. As substitutes for flares, flare tubes that do not use fire (see, for example, Patent Document 1) and emergency signal lights using dry batteries (see, for example, Patent Document 2) have also been developed.
