JP2011113959A - Warning light - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a warning light capable of recognition from a remote location. <P>SOLUTION: A new warning method capable of projecting a search-light toward the sky as shown in Fig. 1 and understanding a warning sign regardless of obstacles to interrupt a rotary warning light is used. Furthermore, the search-light can be projected to a screen prepared by generating smoke in the sky as shown in Fig. 2 and a warning sign can be projected by effectively dispersing projected light in addition to making of a light-emitting body by utilizing dispersion caused by dust and fog in the sky. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to an emergency warning device using light emitted from a vehicle.

  With conventional warning rotating lights used in emergency vehicles, if there are obstacles or vehicles such as buildings or walls, the rotating lights themselves cannot be recognized by being obstructed by them. For example, on urban expressways, tall noise barriers are provided as noise countermeasures for neighboring residents. For this reason, the curve is blocked by a soundproof wall and the situation beyond that cannot be recognized.

  If there are tall obstacles or vehicles in the field of view, warning rotating lights such as emergency vehicles cannot be seen. Therefore, the present invention provides a warning light that can be recognized even when there is an obstacle by projecting light toward the sky.

  In order to solve the above problems, a warning is projected regardless of an obstacle by projecting light as a warning sign in the air and spatially diffusing and concentrating the light or blinking temporally. Specifically, the warning light is characterized by providing a search light that projects toward the sky.

  When the sky is transparent and light scattering by the projected searchlight becomes insufficient and light emission in the air is difficult to obtain, a smoke device is used to project light as a screen.

  By projecting a searchlight toward the sky, it is possible to transmit warning information even in a place obstructed by an obstacle such as a wall.

  An embodiment of the present invention is shown in FIG. Warning lights are mounted on the car bed and roof. As shown in FIG. 2, even in the embodiment using the smoke generating device, it is possible to mount all the devices on one vehicle. Therefore, any device can be quickly moved and operated in emergency use.

  According to the present invention, even in a situation where warning information cannot be sent by direct light such as a warning rotating light due to an obstacle higher than the vehicle, it can be transmitted because there is no obstacle that hinders the warning in the sky. In other words, it is possible to accurately notify warnings issued by mounted vehicles in a high-rise building or a complicated road environment, and it can be expected to lead to safety measures for emergency vehicles and the like.
