Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oscillating illuminating device that is suitable for illuminating a vehicle's traveling range and working range to people around the vehicle as a safety measure, mainly for work vehicles.

In particular, in work vehicles such as snowplows, forklifts, and backhoes, there is a high risk that surrounding people will be caught in the progress of the vehicle and work, and collisions and accidents involving people have occurred. Although there are many technologies for operators of these vehicles to confirm the safety of their surroundings, it is not enough to say that safety measures are sufficient to encourage operators, and safety measures to encourage people around vehicles are also important.
As one of the safety measures to encourage people around the vehicle, there is a method of illuminating the vehicle to clearly indicate the traveling range and working range of the vehicle to the people around. ing.

As a safety measure mainly for working vehicles, effective illumination is required to clearly indicate the traveling range and working range of the vehicle to surrounding people.

Patent Document 1 discloses a vehicle approaching alarm system as a method of illuminating the vehicle's traveling range and working range to make it clear to surrounding people. It moves at the same speed, and there is no relative speed between the lighting irradiation range and the vehicle. Since the distance between the lighting range and the vehicle is changed according to the speed of the vehicle, a relative speed occurs during this change, but this relative speed is temporary. .

The present invention mainly uses directional lights to illuminate the traveling range and working range of a vehicle and their neighboring ranges in order to clearly indicate the traveling range and working range of the vehicle to people around. An object of the present invention is to provide an oscillating illuminating lighting device in which the illuminating range has a relative speed with respect to the vehicle and is periodically moved.

A lighting device installed in a vehicle, comprising a directional light 1 that clearly indicates a lighting irradiation range 3 on the ground or floor surface, and a swinging device 2 that swings the irradiation direction of the directional light 1. It is characterized by oscillating irradiation to the ground or floor surface in the progress range, the work range, or their neighboring ranges so that the illumination irradiation range 3 has a relative speed with respect to the vehicle and is periodically moved. , a swinging irradiation lighting device.

In lighting irradiation where the lighting irradiation range 3 does not have a relative speed with the vehicle, the movement of light is small when the vehicle moves slowly. Since 3 moves to create the movement of light, the illumination illumination in the present invention exhibits superior attention ventilation performance compared to the former illumination illumination.

The directional light 1 irradiates the travel range, the work range, and their neighboring ranges of the vehicle so that the illumination irradiation range 3 has a relative speed to the vehicle and is periodically moved, Even if the vehicle itself is out of sight, or even if the vehicle is stopped (snow plows may have work equipment in operation even if the vehicle is stopped, so it is dangerous to approach). By periodically moving the irradiation range 3, people around the vehicle can be notified of the presence or proximity of the vehicle.

1 is a perspective view of Example 1. FIG. 1A and 1B are perspective and cross-sectional views of an embodiment of a directional light 1; FIG. FIG. 11 is a plan view of Example 2;

A lighting device installed in a vehicle, comprising a directional light 1 that clearly indicates a lighting irradiation range 3 on the ground or floor surface, and a swinging device 2 that swings the irradiation direction of the directional light 1. It is characterized by oscillating irradiation to the ground or floor surface in the progress range, the work range, or their neighboring ranges so that the illumination irradiation range 3 has a relative speed with respect to the vehicle and is periodically moved. , a swinging irradiation lighting device.

FIG. 1 shows Embodiment 1 of the present invention. In the first embodiment, the irradiation direction of the directional light 1 is oscillated by an electric camera platform as the oscillating device 2 to perform oscillating irradiation. In Example 1, the swing irradiation lighting device is installed in the upper part of the cabin of the vehicle so that swing irradiation can be performed to the travel range, the work range, and their neighboring ranges of the vehicle. In Example 1, the directional light 1 shown in FIG.

The stronger the directivity of the directional light 1, the more rapid the illuminance fluctuation in the swinging irradiation, which is effective in drawing attention to the surroundings. For this reason, in Example 1, the directional light 1 shown in FIG. The directional light 1 shown in FIG. 2 reflects the light generated from the LED light source 4 by a parabolic mirror 5 to convert it into substantially parallel light, and then refracts it by a cylindrical concave lens 6 to form a line-shaped illumination irradiation range 3. It can irradiate to The directional light 1 can have an illumination irradiation range 3 of various shapes such as an arc shape by designing a reflecting mirror and a lens.

Embodiment 2 of the present invention is shown in FIG. In the second embodiment, the irradiation direction of the directional light 1 is oscillated by an electric camera platform as the oscillating device 2 to perform oscillating irradiation. In the second embodiment, the oscillating illumination lighting device is installed at four locations on the upper part of the excavator body, namely, the front left and right, and the rear left and right, so that the oscillating illumination can be performed in the four surrounding directions, which is the working range of the excavator. . In Example 2, the directional light 1 shown in FIG.

The embodiment and the directional light 1 shown in FIGS. 1 to 3 are merely embodiments of the present invention. It does not limit the swing range and the like.

The swing device 2 is a device that swings the entire directional light 1 by using an electric camera platform or the like to swing the irradiation direction, and also swings a part of the directional light 1, such as only the lens, only the reflecting mirror, or only the light source. A device for swinging the direction of irradiation by moving the laser beam is conceivable.

The oscillating illumination method includes a method in which the directional light 1 is always on, a method in which the directional light 1 is always blinking, and a method in which the directional light 1 lights up when the illumination range 3 moves away from the vehicle and goes out when it approaches. Various methods are conceivable, such as the method of
