A torch (1), which is producible at low cost and is operable comfortably with one hand, irrespective of a gripping position, includes a torch head (2) which has a lighting unit (18), including a housing (3) configured as a gripping piece that extends along a longitudinal axis (L) and has a closed end section (4) at the rear. A linear-travel switch with a slide (5) operates the torch (1). The slide (5) is slidably and captively mounted on the housing (3). The slide (5) is formed in an L-shape with a first section (6) and a second section (9). The first section (6) extends longitudinally and axially along the housing (3) and the second section (9) engages behind (or catches behind) the closed end section (4) of the housing (3), so that the linear-travel switch can be operated in different gripping positions.

In one aspect, a light module is disclosed, which includes a housing providing a hollow chamber extending from a proximal end to a distal end, and a lens positioned in the hollow chamber, where the lens has a lens body comprising an input surface for receiving light from a light source and an output surface through which light exits the lens body, said lens further comprising a collar at least partially encircling said lens body. The light module further includes at least one shoulder on which the lens collar can be seated for positioning the lens within the housing. A light source, e.g., an LED, is coupled to the hollow chamber, e.g., at its proximal end, for providing light to the lens. In some embodiments, an optical window is disposed in the hollow chamber and is optically coupled to the output surface of the lens such that the light exiting the lens passes through the optical window before exiting the light module. In some embodiments, the shoulder can be formed as part of the housing. In other embodiments, the shoulder can be provided by a sleeve disposed in the module's housing.

Wands of the present disclosure have features that increase entertainment value, improve portability, durability, and balance, making the wands especially well-suited for use in creative routines. The wands include a middle section or an end section that at least partially houses a light engine, and at least one pole configured to couple to the middle section or end section in an axially-aligned assembly. The light engine causes the pole to transmit light.

A multi-spectral flashlight includes a housing, a battery disposed in the housing, a power switch, a LED module including a plurality of LEDs which emit different colors of illumination, a LED driver coupled to the LED module, and an alternate illumination selector switch coupled to the LED driver. The LED driver is configured to drive the LED module in a default illumination mode in response to a first user operation of the power switch and a selected alternate illumination mode in response to a second user operation of the power switch. The LED driver is further configured with a plurality of selectable pre-determined alternate illumination modes which include different colors of illumination. The LED driver advances through the plurality of selectable pre-determined alternate illumination modes in response to operation of the alternate illumination selector switch, allowing selection of one of the plurality of modes as the selected alternate illumination mode.

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.

A portable lighting apparatus includes a handle, a light head pivotally coupled to the handle through a plurality of positions via a joint, a battery receptacle supported by the handle, a first light source supported in the light head, a second light source supported in the light head, and a user interface supported by the handle and configured to be selectively actuated by a user to operate the first light source and the second light source. The battery receptacle is configured to receive a rechargeable battery. The first light source includes a laser selectively operable to emit a single light wavelength, and the second light source includes one or more LEDs selectively operable to emit a distribution of light wavelengths.

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.

Currently disclosed is a device for increasing visibility of a guy line at night. The device includes a housing, a light emitting source, a power source, and an on/off switch. The housing having an internal portion, external portion, and an attachment mechanism located on the external portion of the housing locking in place the housing to the guy line. The light emitting source is located within the housing and powered by the power source. The on/off switch is in contact with the power source providing readily activation of the light emitting source. The attachment mechanism may comprise at least one hook portion and a tensioning mechanism. The tensioning mechanism may comprise at least one offset portion. The tensioning mechanism prevents the device from sliding down the guy line.

Lighting devices are disclosed for use with handheld surgical instruments, along with holsters for supporting surgical instruments with lighting devices thereon and kits containing surgical instruments and lighting devices.

Modular and portable solar-powered lighting devices are described. The device may include a handle assembly including a rechargeable battery and a solar panel electrically connected to the rechargeable battery, a mounting assembly selectively attachable to the handle assembly, and a lighting assembly selectively attachable to the handle assembly, the lighting assembly including one or more light sources. The device may have a first configuration wherein the handle assembly is coupled to each of the lighting assembly and the mounting assembly; and a second configuration wherein the lighting assembly is attached to the mounting assembly and not coupled to the handle assembly. These configurations can resemble a flashlight and a headlamp, respectively.
