A smart headlamp system and methods of use thereof are provided herein. A computer-implemented method includes automatically measuring orientation values attributed to a lighting system device worn by a human user, wherein the lighting system device comprises one or more lighting sources; and automatically modulating one or more of the lighting sources based on the measured orientation values.

A light fixture a baseplate having a pair of tabs extending from its opposing edges. A printed circuit board (PCB) attached to the baseplate has an aperture aligned with an aperture in the baseplate. An array of light emitting diodes (LEDs) is disposed on the PCB. A mounting bracket attached to the baseplate includes a strap and a pair of clips disposed at its opposite ends. Each clip engages one of the tabs to secure the mounting bracket to the baseplate. A pair of clamp arms extend from the strap, each including an arcuate central portion. An aperture passes through the strap that is aligned with the baseplate aperture. A power cable passes through the strap aperture, the baseplate aperture, and the PCB aperture. A protective cover protects the baseplate and the PCB, and provides for transmission of light from the LEDs.

The present invention relates to the technical field of plant lighting, in particular to a panel type combined plant lamp, at least including a panel lamp. Any end of the panel lamp is provided with a rotating connection part, the joint of the rotating connection part and the panel lamp is provided with a slide sleeve plate, the slide sleeve plate includes a pulling plate and a bottom plate, the bottom plate is fixedly connected to the panel lamp or the rotating connection part, the pulling plate is fixedly connected to the panel lamp or the rotating connection part, the thickness of the panel lamp is 3 to 40 mm, the slide sleeve plate is internally provided with a slide groove along the length direction, both sides of the slide groove are provided with openings.

A non-lethal dazzling device includes a laser operable in the visible spectrum. The laser can be a relatively low-powered laser, such as a laser having a maximum output power of 2.5 mW, or it can be a higher-powered laser with a drive circuit that lowers the maximum output power to a safe level based on the range of the hostile target from the laser. In certain embodiments, the disclosed non-lethal dazzling device can be coupled to the bridge of a binocular device.

Industrial lighting device including a light source and a sealed housing containing the light source. The housing includes a support delimiting a housing window extending opposite the light source, a window pane sealing the housing window, and a sealing gasket extending along the periphery of the housing window and compressed between the window pane and the support. The device includes a filter extending in front of the housing window, outside the housing. The filter includes a frame defining a frame window which is removably fixed to the housing, in an assembled position in which the frame window is opposite the housing window, and an optical film fixed to the frame and sealing the frame window. The device includes an elastic compression member arranged between the support and the frame.

The LED light and sound ball for emergency responders is activated upon contact after being fired from a launcher to illuminate and direct responders to an area of interest, such as a potential crime scene. The ball includes a clear polymeric, spherical outer casing, and a rectangular, clear inner casing having a circuit board mounted therein. A plurality of rig rods extend through the inner casing and include curved heads that are in close proximity to the inner surface of the spherical outer casing. Upon impact, the outer casing flexes and pushes against one of the curved heads and pushes its associated rig rod inward, thereby closing a contact that triggers a control circuit to continuously illuminate a plurality of bright LEDs and continuously activate a sound generator that emits a foghorn-type alarm. The LED light and sound ball may be thrown or fired from a conventional compressed air launcher.

Certain embodiments of the present disclosure provide weights used as game pieces with shuffleboard game tables. The weights include an opaque base and a light transmissive cap. One or more lamps, such as LED lamps, are mounted within the weight to illuminate the game playing piece. A plurality of weights may be used on a shuffle game table.

A luminaire comprising a circuit board having at least one LED illuminant arranged on the circuit board, wherein the circuit board is arranged in a luminaire housing with a translucent housing section. The circuit board includes a switching device for switching the at least one LED illuminant on and off with at least one reed switch, wherein the reed switch is arranged on the circuit board between at least one power connection and the at least one LED illuminant and is magnetically switchable for disconnecting or connecting a central power supply for the at least one LED illuminant.

An air flow distribution system for cooling server racks includes at least one server rack partially defining a hot aisle and a cold aisle, a first air foil disposed above the server rack, and a second air foil disposed above the first air foil. The first air foil and the second air foil are configured to receive air from the hot aisle, and to form turbulent wake patterns in the cold aisle partially defined by the server rack. The air flow distribution system may include a convex ceiling member above the second air foil. A corresponding method includes causing air to be directed between a first air foil disposed above a server rack and a second air foil disposed above the first air foil to form turbulent wake patterns in the cold aisle. An electrical enclosure assembly includes a receptacle and a cover member configured as an air foil.

Embodiments may utilize a series of exposed fins, which increase the surface area of the heat sink creating additional air flow. As hotter air rises within the system, cooler is drawn into the heatsink. The fins may be exposed on both sides of the longitudinal axis, allowing cooler air to be drawn towards the longitudinal axis above the heatsink and flow upward. This process may cool the fins. Additionally, the spacing between the fins may have to be wide enough to allow for air to freely enter the heatsink.
