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.

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.

A remote control operation of an illuminated unit attached to a headset consisting of a headband and at least one optical device providing illumination at a known distance from the optical device attached to the headband is disclosed. The remote control unit incorporates a sensing unit that causes power to be switched on and off by the detection of motion in front of the sensing unit. In addition, the illumination may be increased or decreased based on a signal strength of a detected remote sensing signal.

A flashlight may include a housing supporting a light source, a lens, a parabolic reflector and an energy source operatively connected to the light source. An adjustable light beam reflector may be mounted on the housing to intersect/deflect all or a portion of the collimated light rays projected by the flashlight. The adjustable reflector may be movably mounted on the housing for manipulation by a user to produce a wide range of light beam shapes or patterns forward of and/or generally lateral relative to the forward end of the flashlight.

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 apparatus for a vehicle may include a lamp housing part mounted on a vehicle body, a projection optical system disposed within the lamp housing part and configured to radiate light, and a reflection part rotatably disposed in a light path of the light radiated by the projection optical system and configured to reflect, toward a lighting-up surface of the vehicle, the light radiated by the projection optical system.

A portable lighting device for providing illumination includes a body dimensioned and sized to the held by one hand, and adapted to contain a power source therein. A head on the body has a recess in which a light source in the recess is electrically as connected to the power source. The recess and the light source are configured to generate a unidirectional light pattern. A switch enables the light source to be selectively energized by the power source, and a volumetric optical unit is configured for attachment to the head over the recess and the light source to generate an isotropic light pattern.

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 a numeric value for a color change associated with the optical device setting value by calculating a position change value for at least one color filter, the position change value based on the optical device setting value; for the at least one color filter, calculates a modified color filter position based on the position change value and a current color filter position of the at least one color filter and causes the at least one color filter to move to the modified color filter position.
