A high bay luminaire includes a heat sink having a substantially disc-shaped configuration. A light emitter is connected to the heat sink. A reflector is connected to the heat sink. A yoke is connected to the heat sink. The yoke has a first arm, a second arm, and a top bar. A driver is connected to the yoke so that the driver extends between the first arm and the second arm.

A light fixture for high temperature lights with a fluid cooling system operably secured thereto designed to provide optimal cooling using minimal resources and materials. The fluid may be air, water, coolant or the like. An improved heat sink positioned between the cooling fluid and the light provides optimal fluid flow geometries and creates at least one of three possible optimized cooling conditions: First, by forcing fluid to rush through one or more restricting apertures its velocity may be increased by the localized pressure drop. Second, by positioning the heat sink heat exchange structure immediately downstream of the restricting apertures and forcing the fluid flow to change direction while within the confines of the heat exchange structure. Third, the fluid flow may be bifurcated to flow bilaterally through both ends of the heat sink at once in parallel.

An omnidirectional lens is disclosed of the type which captures light from virtually all angles of incidence, and also emits light in all directions. Embodiments are specifically disclosed as a two-way lens that receives light beams from all directions of the compass and directs those light beams to a photosensor. The same two-way lens acts in a “beacon mode” to produce light beams from one or more LEDs, and to emit such light beams (again) in all directions of the compass. The emitted light beams can also be used to signal various functions as visible signals to users on a jobsite.

The present invention relates to a lighting device (300) having a housing (302) and multiple light sources (308) arranged in the housing. The light sources emit light of a first wavelength range. The lighting device includes a wavelength converting member (310) arranged at a distance from the light sources, and it comprises a first wavelength converting material configured to convert a part of said light of a first wavelength range into light of a second wavelength range. The lighting device further includes a color distribution member (312) providing a color distribution of the light emitted from the lighting device where the ratio of intensity of light with the first wavelength range to the intensity of light with the second wavelength range is larger at low angles to a light output surface of the lighting device than at high angles to the light output surface.

A cube for use in a restaurant allowing patrons to more easily notify their server they are in need of something. The cube is equipped with a lighting mechanism that adjusts colors that represent the status of the patrons dining. The cube contains a shell that has an upper surface and lower surface separated by an indent. The cube has a pair of switches that reside within a divot slightly larger in size that the switch. The charging station for the cube has a dock, a layer, and a power supply. The dock has a base equipped with a plurality of dock base towers, each having a plurality of dock tower connections. The dock base has a plurality of base supports each having a central plug. The layer also has layer connection towers each equipped with layer tower connections allowing the layer to function in tandem with the dock base.

A lamp for lighting large, indoor and outdoor environments, comprising a LED light source supported by a LED-holder base interposed between a heat sink and a focusing lens. Said base features such configuration and characteristics as to provide, together with two retaining rings and a deformable core hitch, for a high degree of protection against penetration of solid bodies and liquids and for a high thermal dissipation towards the external environment.

An electrical inflator has a cylindrical shell, an electrical aeration pump, an illumination assembly, a cell base and a switch assembly. The cylindrical shell has a tube, a front cover and a rear cover. The electrical aeration pump is mounted in the tube near the front cover and has a gas outlet located in the tube. The illumination assembly is mounted in the tube towards the front cover. The cell base is mounted in the tube behind the electrical aeration pump. The cell base has at least one cell. The switch assembly is mounted in the tube and electrically connects to the cell base, the electrical aeration pump and the illumination assembly.

A modified sphere structure including: a sphere body with a groove formed on a surface of the sphere body along a distribution path; a light source module disposed in a containing space of the sphere body, wherein the groove is connected to the containing space to define a light releasing space and light emitted from the light source passes through the light releasing space; and a light guiding member filling to the light releasing space to allow the light emitted from the light source to be distributed on the light guiding member along the distribution path and transmitted to outside of the sphere body.

A diffuse light source, for use in energy efficient lighting, as well as for visual disorientation or disruption systems, is configured with a single solid torus (15) or rotating dual cylinder (35a, 35b) diffuser of transparent refracting material into which light (13, 33) from a laser or LED beam source (11, 31) is coupled. Light (19, 39) emerges radially outward in all directions from the diffuser.

A lighting device (23) irradiates a web under conveyance with light. The lighting device includes a light source (43), and an irradiation port (61) configured to open linearly in a widthwise direction of the web at an end portion facing the web. The irradiation port (61) is formed between first and second parallel portions (62b, 63b) where a first plate member (62) and a second plate member (63) parallelly face each other. The web under conveyance is irradiated with linear light. It is possible to provide a lighting device capable of irradiating only an inspection region of a sheet or a web with light.
