Disclosed is an adjustable round light spot torch, comprising a shell (1), a light source (2), and a control optical path (3), both the light source (2) and the control optical path (3) are arranged in the shell (1), the centres of the light source (2) and the control optical path (3) are on the same straight line, the control optical path (3) comprises a first light condensing group (31) and a second light condensing group (32) that are arranged in sequence, and the first light condensing group (31) is located between the light source (2) and the second light condensing group (32). Light emitted by the light source (2) can be condensed by the first light condensing group (31) firstly, and is then diffused to the second light condensing group (32) after passing through a light filter, a condensed light spot is obtained and emitted after the second light condensing group (32) condenses the light for the second time, and consequently, a concentrated and long-range light ray is obtained, and a projected object can appear layered and transparent like a crystal. During use, a relatively long range can still be realized without changing focal length, and a transmitted light spot is uniform and round. The adjustable round light spot torch is simple in structure and convenient to use.

The invention provides a multi-functional flashlight includes an elongated housing with a forward end and a back end and a head unit extensibly connected to the forward end of the elongated housing; the head unit has a first and second part, which are rotably connected to each other such that the rotation of the first part with respect to the second part causes a beam angle of a lighting element to adjust; a clip is affixed to a side of the housing as is a rotary switch for turning the lighting element on or off; and a battery system is positioned within the housing and is operably connected to and enabling the lighting element to emit light.

A multiple functional lighting apparatus includes a light casing having a light opening and defining an opening rim therearound, a light module supported in the light casing for light generation through the light opening, and a light cover having a sealing rim frictionally engaged with the opening rim of the light casing in a waterproof manner to enclose the light opening thereof and to diffuse the light from the light module.

A light adjustment module is suitable for being disposed on a transmission path of a light beam. The light adjustment module comprises a housing, a moveable plate, a diffuser, and a light sensor. The housing comprises a base and a cover connected to each other. The cover has a light entrance. The moveable plate is disposed between the base and the cover. The moveable plate moves relative to the housing along a moving direction. The diffuser is disposed on the moveable plate and the transmission path of the light beam from the light entrance. The light sensor is disposed on the base to sense the light beam from the diffuser. The diffuser has at least two regions arranged in the moving direction. The at least two regions respectively have different optical properties. The light beam has different brightness after respectively passing through the at least two regions.
