Description

Technical Field

[0001] The utility model relates to the technical field of lighting for road construction, in particular to lighting equipment for road construction. Background Art

[0002] In road construction, the use of lighting is crucial, especially in construction environments where work is done at night. Commonly used lighting equipment includes handheld lamps and lighthouses. Handheld lamps have low power and a limited lighting range, while lighthouses have high power and are high-brightness devices. However, they are often used in fixed locations and cannot be moved. They illuminate distant places to remind workers and road operators. However, due to their fixed use locations, they cannot illuminate the required work locations or illuminate multiple locations.

[0003] The existing lighting equipment for road construction cannot combine the advantages of handheld lamps and lighthouses. When the lighting range is large, it cannot be flexibly held and controlled to use the lighting range. For example, a temporary construction lighting lamp disclosed in publication number CN219995230U includes a base, and a movable adjustment mechanism is arranged on the base. The movable adjustment mechanism includes four fixed blocks fixedly installed on the bottom of the base. By providing the movable adjustment mechanism, when the lighting lamp is used in temporary road construction, the height of the lighting equipment is adjusted by the mutual cooperation between the various structures on the base, so that the lighting range of the lighting equipment is increased to better meet the road construction at night, and the movable wheels arranged at the bottom can be used to move the position of the lighting equipment during use. The vibration generated by the movable wheels can be effectively buffered and resolved by the cooperation of the spring and the movable block, so as to prevent the lighting equipment from being affected by vibration and affecting its service life. However, this solution cannot flexibly remove the lamp head from the equipment, cannot flexibly change the scope of use, and has a limited scope of use.

[0004] Therefore, it is necessary to invent a lighting device for road construction to solve the above problems. Utility Model Content

[0007] Preferably, heat dissipation fins are evenly arranged on the power supply mechanism, a socket is provided at the bottom of the power supply mechanism, and a handle can be rotatably connected to the power supply mechanism.

[0008] Preferably, the socket is locked with an axle latch, and the power supply mechanism and the base plate are locked by the locking of the axle latch and the socket.

[0009] Preferably, the bottom plate is a rectangular plate, and a storage groove is provided on the bottom plate. The surface of the storage groove is an arc surface, and the curvature of the storage groove matches the curvature of the surface of the handle.

[0025] The entire lamp head 1 can be bright enough to meet the lighting needs of road construction. At the same time, the lamp head 1 can be moved to any suitable position for use, thereby expanding the scope of use and being able to illuminate from a high place.

[0026] The socket 203 is locked with the shaft pin 403, and the power supply mechanism 2 and the bottom plate 4 are locked by locking the shaft pin 403 with the socket 203. The bottom plate 4 is a rectangular plate, and a storage groove 401 is provided on the bottom plate 4.
