[0005] [Patent Document 1] European Patent Application Publication No. 3431659 [Patent Document 2] European Patent No. 3214223 Summary of the Invention [Problem to be solved by the invention]

[0006] The object of the present invention is to provide a road paving machine or feeder vehicle in order to overcome the above drawbacks. To provide an improved construction machine.

[0007] This object is to provide a construction machine in the form of a road paver or feeder vehicle having the features of claim 1. or a construction machine in the form of a road paver or feeder vehicle having the features of claim 8. This problem is solved by the method of operating the lighting equipment.

[0008] Further advantageous developments of the invention are set forth in the dependent claims. [Means for solving the problem]

[0009] The construction machine according to the invention in the form of a road paver or feeder vehicle comprises a chassis and a hopper. and at least one lighting fixture is attached directly or indirectly to the chassis. The lighting equipment comprises at least one light source. The lighting equipment is The area in front of the machine is illuminated. The construction machine is located in front of the construction machine in the direction of travel. an object detection system for detecting an object, and the light emitted by the lighting fixture is The object detection system changes the image depending on the object.

[0010] This makes it less likely to dazzle the truck driver and allows the truck driver to take better control of the direction. This makes it easier to operate trucks approaching and docking with construction machinery. This allows for safe driving when backing the truck towards construction machinery and when moving the truck towards the construction machinery. The effort required by the truck driver to dock with the machine is reduced.

[0011] In one efficient embodiment, the illumination emitted by the lighting fixture is transmitted to an object detection system. This allows the track to be built without any need for a power supply. When backing up towards the construction machine, the worker does not need to manually stop the machine. and thus labor is reduced.

[0012] Preferably, the illumination emitted by the light source is dimmable, thereby reducing the risk of dazzling. enough to allow the area around the construction site to be visible in the dark while reducing the risk of damage. It can provide light that is useful not only to the operator of the construction equipment itself but also to other construction workers. .

[0013] In a preferred embodiment, the illumination emitted by the light source can be turned off. This allows truck drivers to back up without being dazzled.

[0014] In an alternative embodiment, the light source may be rotated in a direction different from the direction of travel. This allows truck drivers to back up without being dazzled.

[0015] The lighting equipment has a movable cover for the light source, and the light source is covered by the cover. It may be useful to have at least partial coverage. This will allow for easier truck operation. The hands can be backed up without getting dizzy.

[0016] The lighting equipment is a first light source for short distances in the forward direction of the construction machine, and a second light source for short distances in the forward direction of the construction machine. and a second light source for long distances in the forward traveling direction, The illumination emitted by the object detection system is selectively varied in response to the detection of an object. It is further proposed that trucks can be driven at night in the direction of construction machinery. When the vehicle is retracted and docked with a construction machine, for example, the light source for long distances can be selectively turned off. This allows for a short-distance light source to remain lit so that the immediate surroundings of the construction site can be seen.

[0017] The present invention also provides a method for operating lighting equipment on construction machinery in the form of road pavers or feeder vehicles. 1. A method, comprising: a construction machine having a chassis; and at least one light fixture attached to the chassis. The lighting equipment has at least one light source, and the lighting equipment The present invention relates to a method for illuminating an area in front of a construction machine. an object detection system for detecting an object located in front of the vehicle; When an object is detected, the light emitted by the lighting fixture automatically changes depending on the object detected. This will improve the truck driver's direction and improve the truck's This makes it easier for the drone to approach and dock with the construction equipment.

[0018] In one efficient embodiment, the method according to the invention involves the use of a luminaire to illuminate the luminaire. The brightness is automatically changed in response to the detection of an object by the object detection system. When backing the rack towards the construction machine, the operator must manually turn off the power to the construction machine. This eliminates the need for the "f" process and reduces labor.

[0019] In one advantageous embodiment, in the method according to the invention, the illumination emitted by the light source is When an object is detected, the light is dimmed, reducing dazzling and making it ideal for construction sites. It can provide enough light to make the surrounding area visible in the dark, Useful for construction work.

[0020] In a further advantageous embodiment, the method according to the invention comprises the step of: The light is turned off when an object is detected, preventing the truck driver from being dazzled. You can back up without any hassle.

[0021] In an alternative embodiment, the method according to the invention comprises the steps of: This allows the truck driver to back up without being blinded. can.

[0022] In an alternative embodiment, the method according to the invention comprises a lighting fixture comprising a cover and a light The source is at least partially obscured by a cover, which allows the truck driver to You can back up without being dazzled.

[0023] In an alternative embodiment, the method according to the invention comprises the steps of: The first light source is for short distances in the direction of travel, and the second light source is for long distances in the direction of travel ahead of the construction machine. and a second light source, wherein the illumination emitted by the first light source and the second light source is This allows the truck to be driven at night. Select a light source for the long distance when backing up towards the construction machine and docking with it. The light source for short distances can be turned off automatically, so that the light source for short distances can be seen in the immediate surroundings of the construction site. It will stay lit so that you can see it. [Brief explanation of the drawings]
