An example horticulture device includes a housing. The housing includes a central cavity having an inlet and an outlet in fluid communication with the inlet through the central cavity. The horticulture device also includes at least one heat sink fixed relative to the housing. Each of the at least one heat sinks include a main body and a plurality of fins extending therefrom, a plurality of passages being provided between the fins of the at least one heat sink, between adjacent ones of the at least one heat sinks, or both. The horticulture device also includes at least one light source fixed relative to the at least one heat sink and in thermal contact with the at least one heat sink, and a fan disposed within the housing and configured to pass air through the plurality of passages and into the central cavity. A method is also disclosed.

A lighting and scorekeeping system particularly applicable to leisure games is disclosed herein. The system is further applicable to games played to a score of twenty-one. Additionally, the system can be operated and customized locally or remotely with a wireless ad hoc network. Light arrays are programmable and/or addressable and uniquely laid out. One or more epoxy inlays are included for ambiance and partial light transmission. In a preferred embodiment, the system is configured to a cornhole game board.

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.

A light fixture attached to an elongate tubular structure includes 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) are 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 and engage an arcuate central portion having a curvature that matches the curvature of the elongate tubular structure. 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. The power cable includes power wires that are electrically connected to the PCB for providing power to the LEDs. A protective cover protects the baseplate and the PCB, and provides for transmission of light from the LEDs.

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.

A Light-Emitting Diode (LED) light apparatus has a housing and a printed circuit board (PCB) received in the housing. The PCB has one or more first openings and one or more LEDs on a front side thereof about the first openings. The housing has a rear-wall structure with a plurality of fins spaced from each other and one or more second openings at locations corresponding to those of the first openings for heat management. The LED light apparatus may also have a plurality of rotatable LED panels having PCBs and LEDs thereon. The LED panels are spaced from each other with gaps therebetween for heat management, and are rotatable for controlling light distribution, light angular-span, and light direction. A LED grow-light system uses a light-distribution structure such as reflectors and/or fiber-optic cables for distributing at least a portion of the light towards the plant.

The disclosure generally relates to generating lighting in an efficient way while in the outdoors. The designs are meant to maximize the amount of light generated, by the smallest assembly that is rugged to use in general outdoor activities and water sports. Further designs are related to hands-free mounting capabilities on outdoor equipment such as bikes, surfboards, snowboards and other similar equipment. Additional features include various filters, waterproofing, recharging or lighting differences which provide greater visual or photographic advantages to the user.

An underwater lighting system includes a light housing. The light housing includes a weighted base having a bottom surface with a bottom edge and a cover. The cover and the weighted base cooperate to define a cover interior. The cover interior is waterproof. The light housing also includes a light source positioned within the cover interior. The underwater lighting system is configured to prevent a fishing lure or cast net from snagging on the underwater lighting system.

A show effect system may include a plasma tube configured to generate an electric arc within the plasma tube and a light strip extending along the plasma tube. The light strip may include a plurality of light emitters configured to output light through the plasma tube and backlight the electric arc generated by the plasma tube.

An industrial lighting device includes a driving module, a main light-emitting module and a top light-emitting module. The driving module has a top surface and a protrusion portion. The main light-emitting module is fixed at the protrusion portion. The top light-emitting module is disposed on the top surface, and includes a heat dissipation base, a top light source board and a top cover. The heat dissipation base is provided with a base body, an outer wall and a central fixation portion. The central fixation portion is disposed at the center of one side of the base body. The outer wall is disposed on the base body and surrounds the central fixation portion, such that an accommodating space is formed between them. The top light source board is disposed in the accommodating space and the top cover is disposed on the outer wall in order to cover the accommodating space.
