Description

Technical Field

[0001] The present invention relates to the field of area lamps, and in particular to an area lamp. Background Art

[0002] Area lights are used to illuminate worksites or other areas that do not have permanent lighting fixtures, outdoor spaces, or spaces without electricity. These worksites are often located in remote locations, requiring the area lights to be transported to the worksite. The worksite may be located in a location that is not maneuverable by a vehicle, requiring the operator to carry the area lights to the worksite. Many portable lights, such as handheld flashlights or small lantern-style lights, are easy to carry to the worksite, but do not provide enough light to illuminate the area to provide suitable working conditions. Other larger lights are able to provide adequate lighting to the worksite, but may not be easy to transport.

[0003] Chinese invention patent application (publication number CN210266995U, publication date: 20200407) discloses an area light, including a base having a first end and a second end; a pair of legs rotatably coupled to the first end of the base, wherein the pair of legs rotate toward the base when the light is in a stowed configuration, and rotate away from the base when the light is in an open configuration; and a light body having a lamp head. The light body is rotatably coupled to the base on the first end of the base, wherein the light body rotates toward the base when the light is in a stowed configuration, and rotates away from the base when the light is in an open configuration. A light deployment mechanism couples the light body to the base. The light deployment mechanism is adjustable to move the light body between the stowed configuration and the open configuration.

[0004] The existing technology has the following shortcomings: when the area lamp is in the stowed configuration, the lamp head is located at the front end of the base and faces outward. When the area lamp is moved and transported, other objects are likely to contact and collide with the unprotected lamp head, thereby causing the lamp head to be damaged due to collision, reducing the service life of the lamp head. At the same time, the protruding position of the area lamp head makes the area lamp as a whole irregular in shape, which is inconvenient to store. It is also inconvenient to stack multiple area lamps up and down for storage. Each area lamp can only be stored separately, which increases the storage complexity and storage space of the area lamp. Summary of the invention

[0005] The purpose of the present invention is: to address the above-mentioned problems, to propose protection for the lamp head, to reduce contact and collision between other objects and the lamp head when the area lamp is moved and transported, and to increase the service life of the lamp head; at the same time, the lamp head can be flipped and folded so that the entire area lamp is in a regular shape for easy storage, and multiple area lights can be stacked up and stored, thereby reducing the storage complexity of the area lamp and reducing the storage space.
