The present disclosure provides an artware with a water stirring function and a projection function. The artware includes a housing structure, a control circuit board including a switch, a magnetic rotating unit controlled by the control circuit board, and a projection unit controlled by the control circuit board. The control circuit board, the magnetic rotating unit, and the projection unit are arranged in the hosing structure.

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 present disclosure provides a safety light. The safety light includes a top housing; a printed circuit board assembly coupled to the top housing, the printed circuit board assembly having a top surface and a bottom surface; a plurality of light elements coupled to the bottom surface of the printed circuit board assembly, the printed circuit board assembly programmed to energize the plurality of light elements following depression of a first control button; a lens coupled to the bottom surface of the printed circuit board assembly and the plurality of light elements, the lens having a first angled reflective surface and a plurality of side surfaces; and a bottom housing coupled to the lens.

A portable lantern light is configured to be operated in a range of selectable operational modes to provide flexible illumination solutions in both stationary and portable situations. The lantern light includes an elongated central body with a plurality of external longitudinal ribs, longitudinal channels positioned between a pair of external ribs, a lighting element residing within the channel, and a lens overlying the lighting element that acts as a primary optic. A power source that includes a battery cartridge is removably inserted within a receiver of the central body. The lantern light includes an operating mode selector assembly to control which lighting elements are illuminated during operation of the portable lantern light, and a luminosity selector assembly to selectively control the lumen output (brightness) of the lighting elements. The lantern light also includes a retractable stabilization assembly that can be deployed to stabilize the light on a support surface.

Provided is a cross-country running lamp which includes a lamp body, at least two lamp heads and at least one switch. The lamp heads are disposed on a peripheral side of the lamp body for illumination. The switch is disposed on the lamp body for controlling on-off and brightness of the lamp heads.

A portable light may employ a light source positioned adjacent an optical element. The light source may be configured as a light emitting diode generating light with a wavelength primarily within the range of 530 nm to 700 nm with a relative peak intensity of 550 nm to 650 nm. The optical element may be configured to manipulate the emitted light into a beam or other light pattern having specific characteristics such as a certain diameter and/or shape, a certain amount of spill, and/or a certain amount of backscatter. Certain embodiments may be especially useful for emergency and rescue operations performed under conditions such as fire generated smoke.

A lighting device is disclosed having a plurality of light emitting diodes of varying light intensities 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 of different light intensities.

A lens is provided. The lens comprises a lens body. The lens body is substantially in a shape of a circular table. A small end of the lens body is provided with a concave inner light source accommodation space. The inner surface of the light source accommodation space is an incident surface of light. A surface of a large end of the lens body is an exit surface, and a side surface of the lens body is a reflecting surface. A bottom of the light source accommodation space is provided with a cylindrical protrusion. A cross section dimension of the light source accommodation space gradually decreases, from the small end of the lens to the large end of the lens. The cylindrical protrusion is formed by protrusion from the bottom of the light source accommodation space toward the small end of the lens body.

A luminaire includes a receiving element for a rotationally symmetrical glass body with a receiving opening, a rotationally symmetrical glass body arranged in the receiving opening and an annular, permanently elastic element arranged between the receiving element and the glass body, wherein the receiving element is formed with a support surface which is inclined towards the glass body and the glass body is formed with a receiving surface diametrically opposite to the support surface. The permanently elastic element is positioned in the installed state between the support surface and the receiving surface in order to fix the receiving element and the glass body positively and concentrically to each other. An annular gap is provided between glass body and receiving element for introducing the annular, permanently elastic element between support surface and receiving surface. A method for fastening the glass body in the receiving element is provided.

A portable light may comprise: a light body having an illumination, e.g., white, light source and one or more laser light sources, each light source being selectively energizable for producing light; and a switch for selectively energizing the illumination light source and/or the laser light sources. The one or more laser light sources provide diverging narrow beams of laser light, so as to appear as spaced apart dots or spots of laser light on objects illuminated by the beams of laser light. Because the laser light beams diverge, the distance between the dots is proportional to the distance to the object which the dots illuminate. A TIR optical element may also be disposed in front of the illumination light source for receiving the light produced thereby.
