A string light assembly having a plurality of light components is described. Each light component comprises a first cover, a second cover, and a collar for coupling the first and second covers together. When coupled, the first and second covers form a housing that has an interior space. The interior space is sized and dimensioned to house an electrical socket and a pair of electrical wires. The electrical socket electrically and removably couple with a light element such as an LED bulb. The light component also includes a lampshade that either removably couples with the collar or is integrally formed with the light element.

The disclosure includes a convertible light device comprising a housing, a battery pack coupled to the housing, and an elongate flexible light source detachably coupled to the housing and electrically coupled to the battery pack, where the elongate flexible light source comprises a plurality of LEDs. In some embodiments, the convertible light device is configured to convert between a rope mode and a lantern mode. In the rope mode, the elongate flexible light source may be configured to extend from the housing and couple to an external anchor. In the lantern mode, the elongate flexible light source may be configured to wrap around the housing.

Various embodiments described herein are directed to luminaire components that prevent flame transmission from the inside of a luminaire to the outside of a luminaire. In certain aspects, the luminaire can be used in an environment containing flammable gas, for example, in specialized lab work or testing applications. This application discusses components that can be used to prevent flame transmission from the inside of a luminaire to the outside of a luminaire, thereby yielding a flame encapsulating luminaire. Accordingly, the components and assemblies described herein can be safely integrated with systems that operate in the presence flammable gas.

A snow shield assembly for use with a traffic signal is described. The snow shield assembly typically comprises a shield collar, lens shield, extension ring, and mounting assembly. In some variations, a signal visor may be further included. The snow shield assembly can be retrofit for use with existing traffic signals. The design and configuration of the snow shield assembly creates a gap between the lens shield and the shield collar, providing a second egress for blowing snow in addition to the open bottom portion of the existing signal visor, helping to prevent the obstruction of the signal lens by falling snow. Further, the extension ring permits use on traffic signals having louver covers over the signal lenses.

Apparatus and methods for lighting. The apparatus may include a beam-angle changing lens. The beam-angle changing lens may be movable from a first position in front of a slotted cylinder to a second position in front of the slotted cylinder. The slotted cylinder may be fixed with respect to translation along the central axis. The slotted cylinder may be configured to move the beam-angle changing lens from the first position to the second position when the slotted cylinder is rotated. The slotted cylinder may be configured to displace the support to move the lens to the positions. The apparatus may include a guide pin. Rotation of the slotted cylinder may displace the guide pin linearly in a direction parallel to the axis. Motion of the guide pin may move the lens. The apparatus may include a rotatable shaft. The rotatable shaft may be configured to rotate the slotted cylinder.

A curtain lights kit including a curtain lights device including a set of two curtain lights assemblies each having a preformed bendable wireless fidelity/short range wireless light emitting diode light strip for displaying in a common window frame; roll of magnetic polarity-A tape; roll of magnetic polarity-B tape; pin light emitting diode female to female connector cables; pin light emitting diode female to female butterfly connector cables; mateable pin light emitting diode male connectors; first AC/DC power supply adapter; second AC/DC power supply adapter; quick reference codes; curtain lights kit/curtain lights device instruction manual; portable curtain lights storage case, a first curtain lights assembly including a first preformed curtain including a first wireless fidelity/short range wireless controller having a first wireless fidelity/short range wireless combination chip, and a second curtain lights assembly including a second preformed curtain including a second wireless fidelity/short range wireless combination chip.

A light fixture includes a housing adapted to secure the light fixture to a building. A lamp may be mounted to the housing. The light fixture further includes an actuator configured to move the device to move between a retracted position and an extended position so that the lamp can illuminate an area around the building.
