摘要： A lamp includes at least two illumination parts and a lamp body. The lamp body has an upper portion, a lower portion corresponding to the upper portion and at least two optical cavities extended between the upper portion and the lower portion. The illumination parts are respectively arranged in the optical cavities. The lamp has a surrounding lighting state and a side lighting state. The lighting states of the lamp may be switched between the surrounding lighting state and the side lighting state through controlling the operating modes of the illumination parts in the optical cavities respectively.

摘要： A portable lamp includes at least one lighting device and at least one handle body. The at least one handle body has two end portions and a turning space defined between the two end portions. The at least one lighting device is rotatably mounted between the two end portions of the at least one handle body. The at least one lighting device is selectively arranged to be maintained in the turning space of the at least one handle body as a folded state and rotated with the at least one handle body to have an included angle between the at least one lighting body and the at least one handle body as an unfolded state. The portable lamp can adjust the state of the at least one lighting device without moving the at least one handle body.

摘要： 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.

摘要： An adjustable headlight includes a headband and an adjustable illumination device mounted on the headband. The adjustable illumination device includes a light source, a lens, a rotating shell, a first adjuster, a second adjuster, a tubular electrical conductive rack, and a base. The light source is electrically connected to the top end of the tubular electrical conductive rack. The lens is mounted on the front end of the rotating shell. The first adjuster is rotatably connected to the rotating shell. The second adjuster drives the tubular electrical conductive rack to be rotatably coupled with the first adjuster and the base. Rotating the rotating shell changes the distance between the light source and the lens, so as to achieve focus adjustment within the adjustable headlight without changing external length of the device. The device is adapted for being worn on the user's head in various circumstances.

摘要： A lighting lamp includes a lamp head, a lamp body and a connector movably connect the lamp head with the lamp body. The light lamp is capable of being switch between a first illumination state in which an 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 cap and the extending direction of the lamp body define an obtuse angle.
