A multi-purpose, hand-held flashlight has an elongated body with a front body portion having a bottle opener and a front engaging structure. The elongated body also includes a rear body portion with a rear engaging structure that is cooperatively dimensioned to interact with the front engaging structure to releasably couple the front body portion to the rear body portion. The rear body portion includes a second substantially cone shaped extent that includes a recessed cutting element. A lighting element assembly is disposed within the elongated body and includes a lighting element printed circuit board coupled to an emitter assembly, a power source, and a switch. The switch is configured to change the operational mode of the emitter assembly. An attachment mechanism is coupled to the second extent of the rear body portion.

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.

An electric powered flashlight configured so that one or more of the battery cells designed to fit within it may be replaced by a fluid carrying vessel that is electrically conducive so that in addition to carrying fluids internally it may be part of the energy transmission circuit within said flashlight. One or both ends of said vessel may have a removable drinking cap.

A combined flashlight and lantern can have a light powered by a metal-air fuel cell that runs, or is activated, by water or an electrolyte such as salt water. The combined flashlight and lantern has both flashlight and lantern configurations. In the flashlight configuration, a head with a distal concave reflector is disposed towards a handle with the light in an aperture of the distal concave reflector to direct light axially. The distal concave reflector is opaque to resist light from emitting laterally therefrom. In the lantern configuration, the head with a distal convex reflector is disposed away from the handle and opposing a proximal convex reflector to direct light radially.

The flashlight with illuminating dome member is intended for use as a flashlight. The flashlight with illuminating dome member generates an illumination with an adjustable field of illumination. By adjustable field of illumination is meant that the flashlight with illuminating dome member generates a field of illumination selected from the group consisting of: a) an omnidirectional field of illumination (such as area lighting); and, b) a directed field of illumination formed from a collimation of the generated illumination. The flashlight with illuminating dome member incorporates a housing structure and a lamp circuit. The housing structure contains the lamp circuit. The housing structure adjusts the field of illumination generated by the lamp circuit. The lamp circuit is an electric circuit.

A luminaire including an LED light source, a plurality of color filters, an optical device, and a control system is provided. In response to receiving an optical device setting value via a data link, the control system moves the optical device according to the setting value, calculates modified positions for one or more of the color filters based on an effect of the optical device on the color of the light beam of the luminaire, and causes the one or more color filters to move to their modified color filter positions, in order to reduce the effect of the optical device on a beam color emitted by the luminaire.

A flashlight has housing with a first mechanical spiral engagement system, a head assembly with a second mechanical spiral engagement system that engages the first mechanical spiral engagement system when the head assembly is coupled to the housing, an LED light source module fixedly held by a heat sink fixedly held by the housing, a power source held within the housing, and a switch assembly, wherein light provided by the LED light source module may be varied by rotating the head assembly relative to the housing while the heat sink, the switch assembly and the power source remain stationary.

The invention discloses an electronic candle, comprising a plastic shell, wherein a spring is arranged inside the plastic shell, an upright metal wire is arranged at the upper end of the spring, a metal ring is arranged at the lower end of the spring, the metal wire is sleeved with an included angle reflecting screen, a plurality of color flame projectors matched with the included angle reflecting screen are arranged on the plastic shell above the spring, a supporting rod with a concave point is arranged on the plastic shell below the spring, a metal hook is arranged at the metal ring bottom, and a driver for driving the soft iron sheet to swing and an overall power supply for supplying power to the driver and the color flame projectors are arranged below the soft iron sheet. The invention achieves a good effect in reasonable structural design and decorative lighting.

A lighting device with improved optical performance and efficiency is provided. The lighting device includes a source of energy, a light source, a reflector and a holder. The reflector has a first open end, a second end, and a parabolic profile extending between the first open end and second end. The focus of the parabolic profile is located outside of the profile. The reflector may also be movable relative to the light source. The lighting device may include a circuit that delivers a pulsed or thermally compensated pulsed current to the light source. The light device may also include a heat sink housing.
