Abstract: A work light includes at least one power supply unit, and at least one light unit, and at least one connection unit. The power supply unit, the light unit and the connection unit are electrically connected with each other. The light unit is detachably and pivotally coupled to the connection unit. When two or more of the light units are provided, the light units are coupled with each other in series via the connection unit. By changing the number of the light units, an overall length of the work light is selectively adjusted to adjust an illumination range of the work light according to different illumination applications.

Abstract: An adjustable lighting lamp includes a lamp head, a lamp body and a connector movably connect the lamp head with the lamp body for adjusting an illumination direction of the lamp head. The connector of the light lamp includes a coupling base connected to the lamp body and a linkage protrusion connected to the lamp head and configured to adjust the light lamp being switched between a first illumination state in which the illumination direction of the lamp head is aligned with an extending direction of the lamp body, a second illumination state in which the illumination direction of the lamp head is perpendicular to the extending direction of the lamp body, and a third illumination state in which an angle between the illumination direction of the lamp head and the extending direction of the lamp body define an obtuse angle.

Abstract: A foldable lamp includes a lamp body, a supporting unit and a connecting device. The connecting device includes a first connecting unit and a second connecting unit. The supporting unit includes a first supporting structure and a second supporting structure. The first supporting structure is rotatably connected with the lamp body through the first connecting unit. The second supporting structure is rotatably connected with the first supporting structure through the second connecting unit. The lamp is placed on a horizontal or hung on a hanger through the second supporting structure.
