Abstract: Present embodiments provide a light fixture having rotatable light modules and an extendable hinged mounting assembly. The light modules are electrically coupled to the light fixture via a cord and a grommet/bracket feature which provides strain relief and a waterproof barrier. The extendable hinged mounting assembly allows the light fixture to be mounted onto a ceiling or other structure while providing a mounted position and an install position.

Abstract: A heat dissipating housing for a lighting device includes a back wall comprising an upper section and a lower section. The housing further includes a sidewall extending down from the upper section of the back wall. The back wall and the sidewall define a cavity of the housing. The upper section of the back wall is elevated from the lower section of the back wall such that when a printed circuit board (PCB) having an uninsulated electrical element on a back side of the PCB is in contact with the lower section of the back wall within the cavity, the uninsulated electrical element is separated from a closest point on the housing by an air gap and a distance that is compliant with an Underwriters Laboratories (UL) spacing requirement. The back side of the PCB faces the upper section of the back wall.

Abstract: 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 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.

Abstract: A housing apparatus for use in a lighting system may include a housing body and a channel-type connection structure coupled to or formed in the housing body. The channel-type connection structure may define a channel having a generally U-shaped cross-section and extending along a length in a first direction perpendicular to the U-shaped cross-section. The channel-type connection structure may be configured to receive and engage at least one first connector inserted in the generally U-shaped channel in an axial direction generally parallel to the first direction, and further configured to receive and engage at least one second connector inserted in the generally U-shaped channel in a perpendicular direction generally perpendicular to the first direction.

Abstract: Systems, methods, and devices for reducing glare or pixilation associated with LEDs are disclosed. The disclosure relates to a light module that includes a cover panel that reduces contrast in the light emitted by LEDs. The cover panel can be mounted on a substrate which can include a plurality of LEDs. Apertures in the cover panel are aligned each of the LEDs and any optic that may be disposed over each LED. A first portion of the light emitted from the LEDs passes through the optic only and into the environment to be illuminated. A second portion of the light emitted from the LEDs passes through both the optic and the cover panel before passing into the environment to be illuminated. The cover panel can be diffuse and can include various characteristics including textures, objects, and angled surfaces that assist in scattering light.

Abstract: A heat sink for an outdoor lighting fixture includes a top portion and a skirt portion. The skirt portion extends down from an outer perimeter of the top portion. The top portion includes an elevated portion and a transition portion surrounding the elevated portion. The elevated portion and the transition portion define a cavity. The top portion further includes a planar portion surrounding the transition portion. The elevated portion is elevated above the planar portion.

Abstract: A multi-functional heat sink includes a top portion and a skirt portion extending down from the top portion. When a light source is attached to the top portion on an underside of the multi-functional heat sink, the skirt portion reduces risk of rain water from reaching the light source and prevents light emitted by the light source from exiting the multi-functional heat sink in an upward direction. The multi-functional heat sink is made from sheet metal.

Abstract: A light module includes a cover, a circuit board, a gasket, a bottom covering, and an optional optic assembly. The cover includes an inner and an outer wall extending outwardly from the cover, where the outer wall surrounds the inner wall and forms a groove therebetween. The circuit board is positioned within the inner wall's profile and includes a plurality of LEDs. The gasket is disposed within the groove. The bottom covering is positioned adjacent to the circuit board and is coupled to the cover. The gasket provides a seal between the cover and the bottom covering. The optic assembly is disposed within the inner wall's profile and between the cover and the circuit board. The optic assembly includes one or more apertures and one or more optics disposed around at least some of the apertures. Each optic is aligned with one or more LEDs.

Abstract: A method of determining ageing effect and cardiovascular risk in a human patient comprising: - (i) measuring the arterial pulse waveform of the patient when the heart is beating regularly, (ii) extracting the frequency dependent components of the pulse waveform, (iii) determining the ratio of the amplitude based value of the first harmonic (H1) to the amplitude based value of a selected higher harmonic to provide an index of arterial ageing, and (iv) Comparing the index to normative values of index of arterial ageing to determine ageing effect and cardiovascular risk. Other methods of calculating the index based on harmonic amplitudes and the phase angle are also disclosed and claimed.
