A portable illumination apparatus having a sterilizing function, the illumination apparatus including: a lamp unit which includes an illuminating light element on an interior side of the lamp unit; a base coupled to the lamp unit by a hinge; and a sterilizing light element located on the interior side of the lamp unit. When the lamp unit is in a closed position with the base, the lamp unit and the base meet at a boundary section to form a cylinder with a top and a bottom. Also, the boundary section is substantially mirror-symmetrical and at least partially U-shaped such that the lamp unit has a longest height line and a shortest height line. Additionally, the illuminating light element is arranged on or along the longest height line and the hinge is formed about the shortest height line.

A lighting system includes a lighting device arranged to attach to a vehicle. The lighting device includes at least two ultraviolet lights and at least one sensor. The sensor determines whether any of at least two areas or zones adjacent to the lighting device are poorly visibly illuminated and/or occupied by personnel, and illuminates these areas or zones with ultraviolet light. The lighting system is configured to operate in conjunction with existing emergency visible lighting and/or flashing visible light systems by using the sensors to sense visible illumination of each individual area or zone provided by the existing emergency visible lighting and flashing visible light systems. The lighting system may be configured to synchronize the illumination of each individual area or zone in ultraviolet light with intermittent absence of visible light illumination in each area or zone from the existing emergency visible lighting and flashing visible light systems.

A hand-held lighting device is disclosed with a handle and a head housing a first and second light source, wherein a longitudinal axis of the head is disposed at a non-parallel angle with respect to a longitudinal axis of the handle. The first light source is annular light emitting diode and the second light source is a light excited phosphor.

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.

Exemplary embodiments of a flashlight having an electronic insect control system are provided. In some exemplary embodiments, a flashlight apparatus is provided, having a head portion comprising a first light source, a tail portion, and a body portion between the head portion and tail portion, the body portion comprising an electronic insect control system, the electronic insect control system comprising a frame portion, a second light source provided within the frame portion, and an electrical grid provided within the frame portion and surrounding the second light source, wherein the electrical grid is configured to generate a voltage.

A portable illumination apparatus having a sterilizing function, the illumination apparatus including: a lamp unit which includes an illuminating light element on an interior side of the lamp unit; a base coupled to the lamp unit by a hinge; and a sterilizing light element located on the interior side of the lamp unit. When the lamp unit is in a closed position with the base, the lamp unit and the base meet at a boundary section to form a cylinder with a top and a bottom. Also, the boundary section is substantially mirror-symmetrical and at least partially U-shaped such that the lamp unit has a longest height line and a shortest height line. Additionally, the illuminating light element is arranged on or along the longest height line and the hinge is formed about the shortest height line.

A lamp (10) constructed as a hand lamp and for static use. The lamp includes a lamp housing (12), a light source in the lamp housing, a lamp mounting (14) for mounting the lamp in a desired position on a surface and a universal joint (24, 26) coupling the lamp housing and the mounting together, whereby the lamp housing is universally adjustable in attitude relative to the mounting.

A flexible light assembly includes an elongated light transmissible jacket, the jacket including an internal vacancy. The assembly includes a substrate disposed in the internal vacancy. The substrate supports light emitters on a first surface thereof, and includes a reinforcing layer that is fixed to a surface the substrate opposite the first surface. The jacket may also include reinforcing fibers. The flexible light assembly is sufficiently flexible to permit bending such that the flexible light assembly can assume a radius of curvature in a range of 1.3 centimeters to 10.2 centimeters.

The invention relates to a luminaire comprising a housing, at least two radiation sources and at least one directing means. The directing means is used to direct the emission of electromagnetic radiation emitted by the radiation sources. According to the invention, the radiation sources are all located in the center of the directing means such that the radiation sources are arranged concentrically with respect to one another. The radiation sources can be switched on and off individually, jointly, or in combination. Each radiation source emits electromagnetic radiation within a constant wavelength range when switched on, wherein different radiation sources can emit electromagnetic radiation within different wavelength ranges.

An apparatus for a lighting device with a rotatable support includes a lamp body, the lamp body is provided with the support capable of rotating relative to the lamp body, the support is provided with a magnetic block, and a lighting port of the lamp body is arranged on the side wall of the lamp body toward the direction of the rotation center line of the support. When the adjustable lighting device is used, the support is fixed on a metal object in a place to be illuminated through the magnetic block and the side face direction of the lighting port of the lamp body can be adjusted by adjusting the lamp body to rotate relative to the support, and therefore the side face lighting angle of the lighting port is adjusted, and due to the fact that the lamp body can rotate relative to the support at any angle, stepless adjustment of the side lighting angle of the lighting port can be achieved.
