Disclosed is a light tube, a light fixture, and a light body. The light tube comprises at least one tube member and at least one flexible filament. The tube member includes a light-transmitting tube and one or more inner layers. The at least one flexible filament penetrates into the tube member. The light fixture comprises a light holder and the light tube. The at least one tube member includes a sealed end and a connecting end. The at least one tube member is mounted on the light holder. The light body comprises the light tube and a light cap. The light cap is fixedly connected with the connecting end of the at least one tube member. A drive power board is disposed in the light cap.

A luminaire includes a light emitter, an asymmetric lens, and a mechanism. The light emitter includes an exit aperture and emits a light beam having an optical axis. The asymmetric lens receives the light beam and projects a projected beam. The mechanism rotates the light emitter about an axis of rotation passing through the exit aperture, thereby moving a point of entry of the light beam into the asymmetric lens. A size and location of a hot-spot of the projected beam varies as the point of entry of the light beam into the asymmetric lens moves. The asymmetric lens includes a long axis, a short axis, and an asymmetric surface, which has a long axis parallel to the long axis of the asymmetric lens. The asymmetric surface is asymmetric in a cross-section taken in a plane perpendicular to the short axis of the asymmetric lens.

First light (L1) is incident on a diffuser (10), and scattered light emerges from the diffuser (10). The diffuser (10) includes one light incident surface (10a) on which the first light (L1) is incident in a first direction and a first light transmitting surface (10b). The light incident surface (10a) is formed on an end surface of the diffuser (10). First transmitted light (L21) emerges from the first light transmitting surface (10b). Second transmitted light (L22) emerges from second light transmitting surface (10c) that is a surface other than the first light transmitting surface (10b) of the diffuser (10). Intensity of the first transmitted light (L21) increases as a direction in which the first transmitted light (L21) emerges approaches the first direction. Correlated color temperature of the first light (L1) is lower than correlated color temperature of the first transmitted light (L21) and higher than correlated color temperature of the second transmitted light (L22).

The invention includes a drop lens that is generally rectangular-shaped and fits over a housing of a light fixture. The drop lens may include two side portions that attaches to and/or engages with the side panels of the housing. The drop lens includes an inner lens that extends between each of the side portions of the drop lens. The inner lens may be preferably constructed of a flexible plastic material so that it can be flexed and bent to engage the side portions of the drop lens. The inner lens disperses the light from the light source, thereby creating a uniform and consistent luminance on the bottom, sides, and ends of the drop lens. Additionally, the invention may include an upper lens that extends between and is slidably engaged with each of the side panels of the housing. The upper lens slides within the housing to hide the light source through a gap or seam between a first drop lens section and the second drop lens section.

A lighting assembly comprises a linearly extending luminaire having an electronic circuit board, an inner lens assembly attached to the forward facing surface of the electronic circuit board, the inner lens including an array of focused light sources, an outer lens disposed over the inner lens assembly, and a heatsink extending along the length of the linearly extending luminaire. A bracket is pivotally attached to the linearly extending luminaire, the bracket having an axis of rotation around a horizontal axis, whereby the linearly extending luminaire is separately rotatable along a horizontal axis relative to the elevated structure. The bracket also has an axis of rotation around a vertical axis, whereby the linearly extending luminaire is separately rotatable along a vertical axis relative to the elevated structure.

A modular lighting system may include a support structure, a plurality of heat sink modules physically supported by the support structure, and one or more light source modules coupled to the plurality of heat sink modules. The plurality of heat sink modules may be arranged in a modular manner such that the number of heat sink modules in the modular lighting system is variable, and each heat sink module may be an integral molded structure defining at least one opening or passageway.
