A portable light and assembly method may comprise: a light body supporting a source of electrical power and a light head having a light source that produces light. A rotating joint may include: a hollow cylindrical central member extending from one of the light body and the light head in a cylindrical bore of complementary size and shape in the other of the light body and the light head, a fastener retaining the hollow cylindrical member in the cylindrical bore, and one or more electrical conductors extending through the hollow cylindrical member of the rotating joint to connect the source of electrical power to the light source. A hinged cover has a latch including an arm member engaging a feature of the light body or including a thumb screw engaging a threaded hole of the light body, to retain the closed cover against the light body.

The mobile terminal provided by the present disclosure includes a terminal body and a control unit. The terminal body is provided with a flash lamp. A zoom lens is provided in an advancing direction of a light of the flash lamp. The control unit is configured to control the flash lamp to switch between a flash mode and a flashlight mode according to an input command. The zoom lens has a plurality of operating states and can converge the light of the flash lamp in at least one operating state. Thus, the mobile terminal can be used as a flash and as a flashlight having a relatively large irradiation distance and further as a flashlight with adjustable irradiation distance.

A flash housing for photographic purposes is disclosed. The flash housing comprises a flash forming element arranged to generate a flash light and a lens element arranged to let at least part of the generated flash light out of the flash housing so as to obtain the flash. The obtainable flash light has a beam lobe with a controllable beam angle. A simulation light generator element is arranged for simulation of the obtainable flash light beam lobe having the controllable beam angle.

A portable lighting device control module configured to intuitively adjust lighting operations of a portable lighting device by interpreting real-time user gestures and external conditions of the portable lighting device to modifying lighting operations in response thereto. The control module installed within a portable lighting device may be configured to permit automatic dimming of front-end LEDs, enable a low power standby mode in absence of motion being detected, automatic mode adjustments in response to low battery determination, adjustment to lantern mode when a bump gesture is detected, continuous alternation between modes within lantern mode by detecting subsequent bump gestures, exiting lantern mode by detecting orientation, locking the lighting operation to a specific mode by determining orienting as either upwards or downwards, switching between modes by performing twist and return gestures, switching between modes by performing whip gestures, instantaneously dimming the light intensity by twisting the portable lighting device.

Gobo projection targeting devices have a light source, a lens assembly associated with the light source, the lens assembly having a first element, a second element, and an aiming figure, the first element being closer to the light source, and the second element having a smaller diameter than the first element, such that a first portion of light emitted by the light source and transmitted by the first element will bypass the second element and a second portion of light emitted by the light source and transmitted by the first element will not bypass the second element. The first and second elements may each be converging lenses. The second element may be adapted to generate an image of the aiming figure away from the illuminator. The first portion of light may be a field illumination pattern lacking a focused image. The lens assembly may be movable.

A multi-function flashlight that includes a flashlight body, an optic having a focusing portion and a non-focusing portion, a main LED positioned to direct light through the focusing portion, and one or more additional LEDs positioned to direct light through the non-focusing portion. A power source may be disposed within the flashlight body adapted to provide power to the main and additional LEDs, and a first control may be included that is configured to selectively provide power to the primary LED.

A rechargeable flashlight has a rear housing containing a rechargeable battery, a charge/discharge circuit for the battery and a first connector fixed to the rear housing and connected to the charge/discharge circuit. A front housing has an LED light source with LED lighting circuit connected to the light source and mounted in the front housing. A second connector is fixed to a rear end of the front housing for connecting to the first connector for supplying power to the LED lighting circuit. A switch is mounted to the front or rear housings and is connected to one of the circuits for powering the light source. A lens housing on the front housing focuses light from the light source and a mechanical coupler fixes the housings and connects to each other.
