Abstract

PROBLEM TO BE SOLVED: To provide a maneuvering lamp capable of improving maneuvering support performance.SOLUTION: A right maneuvering lamp 13 comprises an actuator 20 capable of changing an irradiation range of a road surface by LEDs 26 and 27 in the vehicle longitudinal direction, by relatively moving a case 23 to a vehicle body together with the LEDs 26 and 27. Therefore, the right maneuvering lamp 13 can change the irradiation range of the road surface in response to a travel state of a vehicle. For example, when a shift position is set in a retreat position, attention of a driver can be directed to derailment and contact by illuminating a rear area of the road surface. When the shift position exists in an advance position, the attention of the operator can be turned to rolling-in and road shoulder running-on by illuminating a central area of the road surface. Thus, visibility suitable for the travel state of the vehicle can be provided, so that the maneuvering support performance is improved.

Description

  The present invention relates to a control light and a steering support device using the same.

The vehicle is equipped with lamps such as a headlamp, tail lamp, brake lamp, and reverse lamp. The above lamps are required to be equipped on vehicles traveling on public roads. On the other hand, the vehicle is also equipped with an auxiliary lamp such as a fog lamp disclosed in Patent Document 1. Auxiliary lighting fixtures are optional.
Recently, attention has been focused on control lights among auxiliary lamps. The control light is a lamp that assists the control when the vehicle is traveling at low speed by illuminating the road surface on the side of the vehicle.

By the way, it is necessary to provide the control light so as to conform to the standards defined by laws and regulations. For example, only one steering light can be provided on the side of the vehicle. Further, it is necessary to provide the control light so that the brightness is limited and the apparent surface cannot be seen from a predetermined zone so as not to dazzle the driver and pedestrian of other vehicles. For this reason, the control light can only illuminate a part of the road surface on the side of the vehicle, and there is a limit to the operation support.
The present invention has been made in view of the above-described points, and an object thereof is to provide a control light capable of improving the operation support performance.

  According to the control light of the present invention, the irradiation range of the road surface can be changed by the irradiation range changing means according to the traveling state of the vehicle. For example, when the operating device of the transmission of the vehicle is in the reverse position, the driver can be alerted to wheel removal or contact by illuminating the vicinity of the rear wheel on the road surface. In addition, when the operation device of the transmission of the vehicle is in the forward position, the driver can be alerted to getting involved or riding on the shoulder of the road by illuminating between the front wheels and the rear wheels on the road surface. Therefore, visibility suitable for the traveling state of the vehicle can be obtained, and the steering assist performance is improved. Also, drivers and pedestrians of other vehicles can easily predict the behavior of a vehicle equipped with a control light by confirming the irradiation range of the road surface.
