A linear light fixture assembly for supporting a light fixture in a ceiling structure, comprises a light fixture mounting structure having a pair of opposed boundary regions configured to fit within a designated light fixture receiving region in the ceiling structure, and a plurality of spring elements configured to spaced outwardly from at least one of the boundary regions, each spring element having a mounting region configured to be anchored to the mounting structure and a free end region to extend therefrom and to be laterally outwardly biased in a first position to form a path of contact with a support surface region on the ceiling structure to anchor the structure in the receiving region, each of the spring elements configured to be movable toward the corresponding boundary region in a second position to release the path of contact to release the light fixture from the receiving region.

An aspect of the present disclosure describes a heatsink system, including a single substantially solid core detachable linear heatsink having at least one exterior flat surface, a power management module, a controller, a sensing device, a microswitch, a light source driver, a plurality of heat dissipating fins, and a plurality of lensed light sources coupled to the at least one exterior flat surface. Additionally, according to this aspect, the plurality of the heat dissipating fins and the core of the linear heatsink are a unitary body with the heat dissipating fins extending outwardly from the core and with a length of a first maximum dimension of the core and at least one fin being greater than a second maximum dimension of the core taken perpendicularly to at least one exterior flat surface that retains a light source. Still further, at least one of the power management module, the controller, the sensing device, and the light source driver are electromechanically coupled to the heatsink core, and at least one of the plurality of lensed light sources is coupled to the at least one exterior flat surface and is controlled by the processor to emit ultraviolet (UV) light.

An apparatus for providing reflective lighting. The apparatus includes a light source for providing an initial light wave having first light wave characteristics and a surface having a reflective material which alters the characteristics of the light emanating from the light source, providing a secondary light having second light wave characteristics. The first light wave may not be visible to the human eye and the secondary light may be visible to the human eye. The first light wave may include invisible frequencies which are converted to visible light frequencies upon striking the reflective material.

First adapter (10) and second adapter (40) are each separately securable to a respective automotive light bar (200, 201) at mutually facing lateral light bar end caps (206). The adapters (10, 40) interfit, such as first adapter (10) having one or more tenons (14; 18) received in shape-conforming recess or mortise (44) of second adapter (40). The coupling assembly formed from interfit first and second adapters (10, 40) sufficiently supports a midspan region of conjoined light bars (200, 201) to permit omission of mounting L-brackets (208) conventionally required at the mutually facing light bar ends (206), thus allowing fewer holes to be drilled in vehicle roof or bumper (212) and resulting in an aesthetically cleaner presentation of the overall lengthened light bar assembly.

An optical cover for a linear light source includes a portion of an optical material that forms a cross-section transverse to an axial direction. The cross-section curves so that its inner surface is substantially concave and its outer surface is substantially convex. The outer surface is substantially smooth, and the inner surface forms facets. Each of the facets refracts light, and connects with an adjacent facet. Each of the facets defines a peak height from the outer surface, and each pair of adjacent facets defines a valley height from the outer surface. The peak heights of all facets exceed the valley heights between adjacent pairs of facets, and the peak height of each selected facet does not exceed twice the valley height between the selected facet and a facet adjacent to the selected facet.

A glowstick includes a lighting module, the lighting module including a light source having a primary direction of emission. The glowstick further includes a polymer rod, the polymer rod interfaced with the lighting module, the polymer rod having a length, a depth, and a width, wherein the length is greater than the depth and the length is greater than the width, the polymer rod proximate to the light source such that the primary direction of emission of the light source is aligned with the length of the polymer rod.

Disclosed is a grid lighting system having at least one housing segment with at least one lighting zone. A lighting module is included that has at least one track lighting module and/or at least one non-track lighting module. The lighting zone extends along a first length of the housing segment having at least one first passage to receive the at least one lighting module. The housing segment includes a first power supply segment to be coupled with a designated line voltage outlet to deliver line voltage power to the lighting module in the lighting zone. Each lighting module includes a lighting subzone, with a second passage to receive one or more lighting submodules along a second length. A second power supply segment is provided to couple with the first power supply segment to receive line power and to deliver low voltage to the one or more lighting submodules.

An expanded solar alarm lamp includes a solar cell component, a solar battery, a main controller, a xenon tube lamp, a circuit board, and a PC housing. The solar battery is connected to the solar cell component for receiving solar energy from the solar cell component and storing the solar energy to a battery that supplies electric power to the alarm lamp. The main controller and xenon tube lamp are installed on the circuit board; the PC housing is used for wrapping the circuit board and installed at the top of a car body; the xenon tube lamp is for generating a warning light; and the main controller is for determining whether the electric power supply is provided by the solar battery which is the xenon tube lamp based on the current stored electricity of the solar battery. The invention improves the performance and function of the solar alarm lamp.

Disclosed herein are various embodiments related generally to computer vision, graphics, image scanning, and image processing as well as associated mechanical, electrical and electronic hardware, computer software and systems, and wired and wireless network communications to form at least three-dimensional models or images of objects and environments.
