A multifunctional flashlight support, including a base, a connecting rod assembly and an optical component; the base is connected with the optical component through the connecting rod assembly, a flashlight is installed in a detachable way on the base, and the optical component abuts against the light outlet of the flashlight to serve for changing the light direction of the flashlight. The flashlight is installed on the base of the support, and the direction of light from the flashlight is changed through the optical component, so the original unidirectional direction of the light beam from the flashlight can be changed through the optical component or the light beam is further dispersed to achieve the floodlighting effect, and the flashlight turns into a desk lamp, or a camping light or a wall light giving a wider lighting range, with the lighting function achieved when it is not held by hand.

Provided is a fixture including a base; and a light guide, which is positioned on the base and is configured to receive light emitted from a light source in a first direction and guide the received light to be emitted in a second direction crossing the first direction.

A system and method for visualizing, tracking and maintaining social distancing includes a visible boundary generating device having a lighting unit that is disposed within a main body, a user attachment mechanism and a controller for selectively communicating with an external processor enabled device. The lighting unit functioning to generate a visible zone of colored light in 360 degrees around a user to whom the device is secured. The visible light representing a safe zone having a radius that conforms to a specified social distance. The system also including a social distancing mobile application for execution on a smartphone or other processor enabled device. The social distancing mobile application including functionality for sending location information to a system administrator device, receiving proximity alerts from the system administrator device and providing notification to a user.

An electronically variable lighting device includes a power supply, an input device, one or more first light sources, one or more second light sources, and circuitry interconnecting the power supply and the input device with the light sources. The light sources are configured to produce a light beam shape for producing a desired light beam pattern. The circuitry is configured to control power supplied from the power supply to the one or more first light sources, the one or more second light sources, or both, to vary the light beam pattern. A method of electronically varying a light beam shape to produce a desired light beam pattern by a lighting device includes supplying power to one or more first light sources, supplying power to one or more second light sources, and varying the power supplied to the one or more first light sources, the one or more second light sources, or both.

An optical diffuser for a light may comprise an optical body having a substantially flat base at one end thereof and a complex lens structure at the opposing end thereof. The complex lens may have a plurality of curved optical surfaces and may produce a beam of light having a non-uniform light intensity. The optical diffuser may be attached to a light by a holder, and the holder may be movable on the light to place the optical diffuser in front of a light source.

A flashlight including a lens assembly having an adjusting element; and a light source assembly provided at one side of the lens assembly. The light source assembly includes a first light source, a second light source, an excitation element, and a light path adjusting element. Light emitted from the first light source irradiates the excitation element to generate first exciting light, and light emitted from the second light source irradiates the excitation element to generate second exciting light. The first exciting light and the second exciting light sequentially pass through the light path adjusting element and the adjusting element, and are outputted simultaneously.

An illumination device is provided with an optoelectronic light source and an optical body. The optical body is divided into an inner lens part and an outer reflector part adjoining thereon outward in relation to directions perpendicular to a main direction, which body parts are formed monolithically with one another. The inner part is formed as a Fresnel lens with active flanks which acts as a collimating lens, so that a first part of the light which passes through the Fresnel lens via the active flanks is refracted toward the main direction. A second part of the light which passes through the Fresnel lens via folding flanks is refracted away from the main direction. A reflection surface is provided on the outer reflector part, on which the second part of the light is incident and is reflected thereon and deflected with the reflection toward the main direction.

An LED illumination module including an LED lamp with a plurality of light emitting dies on a substrate in combination with an optic having a single focus. The light emitting dies include a single center light emitting die centered on an optical axis and peripheral dies arranged around the center die. The illumination module includes a beam forming optic having a single focus arranged over the LED lamp with the focus on the optical axis of the center die. Light emitted from the center die is substantially collimated by the optic in a focused spot emission pattern. Light emitted from the peripheral dies results in a more dispersed or divergent flood emission pattern. The center die and peripheral dies are independently controlled and the power delivered to the dies can be varied independently to generate different light emission patterns using the same optic.

A portable light may comprise: a light housing including a first housing and a light head that is pivotable relative to the first housing; one or more light sources including an illumination light source in the light head; an electrical switch for selectively energizing the one or more light sources; and a detector of the pivoted position of the light head relative to the first housing for energizing and/or de-energizing one or more of the light sources. Other features of the light may include: a rear facing light source that may have one or more light sources, or an elongated clip, or a pivotable elongated clip, or one or more accessories mountable to a clip, or a combination thereof.
