An adjustable carrier structure for a lamp is described. Said adjustable carrier structure comprises an optical component carrier on which an optical component may be fastened, a coupling device for fastening the carrier structure on the lamp, and at least one threaded spindle. The latter comprises a first threaded spindle end that is mounted in an axially-fixed and non-rotatable manner on the optical component carrier, and is connected to the coupling device via a threaded socket that cooperates with the threaded spindle. In this case, the threaded socket is connected to the coupling device in an axially-fixed and rotatable manner. The threaded spindle extends essentially parallel to an optical axis of the adjustable carrier structure. A distance may be set between the first threaded spindle end and the coupling device by means of rotating the threaded socket. Moreover, a lamp having a carrier structure of this type is proposed.

A light-producing assembly for a spotlight for illuminating film, studio, stage, event and/or theater surroundings comprises a carrier, on which an LED arrangement with a multiplicity of LEDs is arranged. Here, the LEDs are provided by N>2 different color types. The assembly also comprises a line system for supplying power to the LEDs, which comprises a multiplicity of lines with N line types, wherein lines of different line types cross in crossing regions and the crossing regions lie outside of a vertical projection surface of footprint sides of the LEDs in a vertical plan view of the carrier front side. Further, the assembly comprises an optical unit coupled to the LED arrangement, said optical unit spanning the totality of the LEDs. Moreover, a spotlight comprises such a light-producing assembly.

A lighting device is disclosed having a plurality of light emitting diodes disposed about the same substrate. A lens is configured with a geometry that corresponds to different sections of the substrate containing the light emitting diodes to propagate a beam of light with different characteristics through different portions of the lens.

A flashlight including a lens assembly having an adjusting element; and a light source assembly provided at one side of the lens assembly. The light source assembly includes a first light source, a second light source, an excitation element, and a light path adjusting element. Light emitted from the first light source irradiates the excitation element to generate first exciting light, and light emitted from the second light source irradiates the excitation element to generate second exciting light. The first exciting light and the second exciting light sequentially pass through the light path adjusting element and the adjusting element, and are outputted simultaneously.

A lighting apparatus for use as a surgical headlamp is disclosed. A light emitting diode is positioned in a recess within a frustoconical, thermally-conductive heat sink that has a several circumferential ridges to provide a desired surface area for heat transfer. The diode and the heat sink are provided in a housing that also includes a fan for drawing ambient air into the housing to contact the heat sink and exhausting heated air. A lens is snap-fit into a slide that frictionally engages the interior of the housing, allowing a user to adjust the spacing between the light emitting diode and the lens as desired. Personal cooling apparatuses usable with the lighting apparatus are also described. Auxiliary undergown switches are also described as are personal cooling apparatuses.

Systems and methods for projecting a collimated beam of light from one or more light sources.

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 portable lighting device with an elongated main body that includes a housing with receiver, and a power source positioned within the receiver. An operational mode selector assembly with a switch assembly that is actuated by a user is operatively coupled to the power source. An illumination assembly is electrically coupled to both the operational mode selector and the power source. The illumination assembly has a primary light source with a light emitter that emits light axially along a longitudinal axis of the main body or housing through a lens. A secondary light source with a light emitter emits light substantially perpendicular to the axis to illuminate an indicia located in a side region of the illumination assembly. During operation of the portable lighting device, the components of the illumination assembly are arranged such that: (i) the primary light source does not illuminate the indicia, (ii) the secondary light source does not emit light through the lens, (iii) an appreciable amount of light emitted from the primary light source does not mix with light that is emitted from the secondary light source within the portable lighting device, and (iv) an appreciable amount of light emitted from the secondary light source does not mix with light that is emitted from the primary light source within the portable lighting device.

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.
