The upper sections of the substantially toroidal light housings are made of molded plastic resin reinforced with carbon fibers or glass fibers and the lower sections of the substantially toroidal light housings are made of a clear moldable plastic.

A light-emitting module is adapted for a light-permeable button and includes a substrate, a switch, and a plurality of light-emitting units, the switch is disposed on the substrate and configured to contact the light-permeable button, the light-emitting units are disposed on the substrate and surround the switch, and the light-emitting units are disposed on the substrate, spaced apart by each other, and arranged to correspond to a light-receiving surface of the light-permeable button.

A battery powered lighting device is configured to be attached to lift bucket having sidewalls and an upper lip extending from uppermost portions of the sidewalls. The lighting device includes a main housing, a securing member, and a main light mounted to the main housing and located to illuminate areas outside of the lift bucket. The main housing includes a first securing surface and an upper housing portion, with the upper housing portion configured to be located above the upper lip of the lift bucket with the first securing surface engaged against a surface of the lift bucket. The main light is mounted to the main housing to move between a lower position wherein the main light is positioned below the upper housing portion and an upper position wherein the main light is positioned above the upper housing portion.

A lighting device assembly includes a first optic member having a light entry side and a light exit side, is arranged to receive light from a light source and is configured to emit light in a light beam or pattern having a peripheral edge portion. An aperture member has an optical opening arranged in alignment with the first optic member to pass a portion of the light from the first optic member. The aperture member has a plurality of surface regions surrounding the optical opening. Each surface region is configured to reflect a different respective section of the peripheral edge portion of the light beam or pattern toward the light exit side of the first optic member.

The present disclosure discloses a lighting device, including a base, a cover and a lighting module, the cover is disposed on the base, and a receiving chamber is formed between the cover and the base; the lighting module includes a light source module and a driving power source, the light source module is rotatably disposed on a side wall of the base, the driving power source is disposed in the receiving chamber, and the light source module is connected with the driving power source.

Lights with features for underwater use that provide tailored beam-width and/or other tailored light patterns are disclosed. One embodiment includes a housing having a front end with a port and a back end, a port window having a plurality of lens features positioned at the front end of the housing within or behind the port, and a circuit element, including a plurality of LED lighting elements, positioned behind the window.

An LED lamp includes: a lamp shell; a passive heat dissipating element having a heat sink connected to the lamp shell; a power source disposed in the lamp shell; and a light emitting surface connected to the heat sink of the passive heat dissipating element and comprising LED chips electrically connected to the power source. The power source comprises a power board and a plurality of electronic components mounted thereon. The power board is divided into a first mounting zone and a second mounting zone by an axis, total weight of the electronic components on the second mounting zone is greater than total weight of the electronic components on the first mounting zone, and a heat dissipating element is provided on the first mounting zone to balance the two zones of the power board in weight.

An illumination device includes a plurality of light sources arranged in at least a first group of light sources having one or more light sources and a second group of light sources having one or more light sources and further includes one or more light collectors, each being arranged for collecting light from one or more light sources from the first group of light sources and for converting the collected light into one or more light beams. The first and second groups of light sources are each individually controllable. The first and second groups of light sources are both arranged for emitting light from a space on one side of the one or more light collectors. The illumination device is arranged so that light emitted from the second group of light sources through the one or more light collectors defines a pattern comprising one or more elongated elements.

An LED lamp, in particular a table lamp, comprises a lighting head extending about a central axis; the head comprises: a body shaped as a ring about the axis and provided with a substantially annular seat; a plurality of LEDs arranged spaced apart from one another along the seat and about the axis and supported by a printed circuit board positioned in the seat and having a face, on which the LEDs are positioned, perpendicular to the axis; and a lens positioned in front of the LEDs to close the seat; the lens consists of a monolithic piece extending about the axis and has a concave annular inlet surface, facing the LEDs, and a convex annular outlet surface, substantially aligned parallel to the axis and extending about the axis and shaped so as to generate a rotosimmetric light emission about the axis.

A light-emitting (LED) fountain light with a self-cleaning lens includes a light body with a central hole, a light housing surrounding the light body, a nozzle provided in the light housing and located in the central hole, a central hole pressing ring sleeved in the central hole, LED light beads arranged between the central hole pressing ring and the light housing and sealed by a sealant, a driving mechanism provided between the nozzle and the central hole pressing ring, a cleaning mechanism provided on a surface of the light body to scrape off algae and other dirt, and a transmission mechanism provided between the driving mechanism and the cleaning mechanism. In the LED fountain light, scrapers are rotated forward and backward once to effectively clean the algae and other dirt on the surface of the LED fountain light.
