The present invention relates to a method for manufacturing a linear LED light source, comprising: providing a tubular glass envelope that is open at its proximal end and its distal end; inserting a light source mount assembly comprising one or more LED units into the tubular glass envelope; forming a distal hermetic seal at the distal end such that a distal opening remains at the distal end; forming a proximal hermetic seal at the proximal end such that a proximal opening remains at the proximal end; filling the tubular glass envelope with a gas filling; and sealing the distal and proximal openings to obtain a sealed lamp envelope; wherein a flow of coolant gas through the tubular glass envelope is maintained during the formation of the proximal hermetic seal and/or distal hermetic seal if the light source mount assembly is inserted before the formation of the respective hermetic seal.

A luminaire has a first housing portion and a second housing portion formed of a polymeric material. A hinge pivotably connects the first housing portion to the second housing portion and includes a pintle formed as one-piece with one of the first and second housing portions and a knuckle formed as one-piece with the other one of the first and second housing portions. A sealing structure seals a compartment formed between the first housing portion and the second housing portion. The sealing structure includes a channel supported by one of the first and second housing portions and a frame supported in the channel. The frame supports a deformable gasket. A sealing member extends from the other one of the first and second housing portions where the sealing member extends into the channel and engages the gasket. A locking feature secures the first housing portion to the second housing portion.

Various examples are provided related to boat loaders for trailers. In one example, a boat loader includes a primary tube extending between a first end and a second end and a light tube that can move within the primary tube. The light tube can include light elements extending along a portion of the light tube at a first end and a float attached to the light tube at a second end. The primary tube can be coupled to a trailer at the second end and the first end of the light tube can extend outward from the first end of the primary tube exposing the light elements as the primary tube is submerged in water and can retract into the primary tube as the primary tube is removed from the water.

Solar-powered lighting devices that may be portable and/or collapsible are described. The devices may include a housing including a first wall, a second wall, and one or more side walls between the first wall and the second wall, at least one solar panel to generate solar energy, and a rechargeable battery to store the solar energy generated. The devices may include a plurality of operating modes for controlling lights within the housing, and a microprocessor for controlling the operating modes.

A recessed lighting fixture comprises a generally annular body having a central cavity in the form of a partially spherical socket. There is a lighting support member having a partially spherical exterior portion which is closely fitted within the partially spherical socket of the annular body. The lighting support member is pivotable relative to the annular body, but air flow between the partially spherical socket of the annular body and the partially spherical exterior portion of the lighting support member is substantially restricted. There may be a light source mounted to the lighting support member adj acent a bottom thereof. The light source may be a light-emitting diode.

A lighting module and a lighting device. The lighting module includes: a base, including a bottom plate and a base sidewall disposed on the bottom plate, the base sidewall and the bottom plate enclosing an accommodation groove; a light transmitting component, being partially disposed in the accommodation groove so as to form an accommodating space between the light transmitting component and the bottom plate, the light transmitting component including a light transmitting component sidewall which is oppositely arranged with the base sidewall at an interval; and a sealing component, being partially disposed between the light transmitting component sidewall and the base sidewall, and being in close contact with the light transmitting component sidewall and the base sidewalls respectively so as to seal the accommodating space.

A novel organic compound is provided. An organic compound represented by General Formula (G1) below is provided. Note that in General Formula (G1), one of A and B represents a group represented by General Formula (g1) below, and the other of A and B, R1 to R8, and R11 to R14 each independently represent any one of hydrogen, an alkyl group having 1 to 6 carbon atoms, a cyclic hydrocarbon group having 3 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a cyano group, a halogen, a haloalkyl group having 1 to 6 carbon atoms, and a substituted or unsubstituted aromatic hydrocarbon group having 6 to 60 carbon atoms. R9 and R10 each independently represent any one of hydrogen, an alkyl group having 1 to 6 carbon atoms, a cyclic hydrocarbon group having 3 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a cyano group, a halogen, a haloalkyl group having 1 to 6 carbon atoms, and a substituted or unsubstituted phenyl group. Ar represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.

A linear luminaire having high ingress protection includes a light-generating assembly and a channel. The light-generating assembly is an elongate, self-contained, sealed optical assembly that includes all elements necessary to generate light and to direct, focus, or modify the generated light in a particular way. Typically, the light-generating assembly would include an outer optical element and a light source positioned within a cavity of the body of the light-generating assembly. The outer optical element may be a lens, diffuser, or other such element. The light source may be a strip of LED linear lighting, a string of connected LED modules, or any other suitable device. The light-generating assembly may optionally include a second optical element, such as a lens or diffuser, that is supported within the body. The ends of the body of the light-generating assembly may be sealed by fitted endcaps, by polymeric resin, or by other means.

An underwater lighting system includes a light housing. The light housing includes a weighted base having a bottom surface with a bottom edge and a cover. The cover and the weighted base cooperate to define a cover interior. The cover interior is waterproof. The light housing also includes a light source positioned within the cover interior. The underwater lighting system is configured to prevent a fishing lure or cast net from snagging on the underwater lighting system.
