In some embodiments, a lighting assembly including at least one light-emitting device positioned within a housing is disclosed, wherein the housing is designed to allow an ambient environment to pass into the housing and transfer heat from the at least one light-emitting device. The light-emitting area of the light-emitting device may be sealed from the ambient environment. In some embodiments, the housing may include at least one recess, port, or other opening configured to allow a liquid or gas to promote heat transfer from the light-emitting device. In some embodiments, a vehicle, a marine system, or other systems may include at least one lighting assembly as contemplated herein.

The present invention discloses a lamp structure. An accommodating cavity is provided for disposing a lamp board. An insulating unit seals the opening of the accommodating cavity for preventing accidental electric shocks when a user cleans or maintains the lamp structure. Placing the lamp board inside the accommodating cavity, the space occupied by the lamp board on the base may be saved. The insulating unit may prevent foreign matters or water from contacting the lamp board and resulting in short circuit or failure in the lamp board. One or more heat dissipating unit may be disposed in the accommodating cavity and used as the heat dissipating structure for the lamp board. A recess may be disposed on an inner side of the accommodating cavity. The recess communicates with the accommodating cavity. A capacitor may be disposed in the recess and connected electrically to the lamp board.

A COB LED lighting lamp cooled by a liquid agent, in particular water, used for year-round illumination of the LED light of this lamp in a greenhouse of plants and includes a load-bearing and lighting component, having a cooling plate with three threaded mounting openings arranged transversely, the inner surface of which with channels for the cooling liquid flowing through it is permanently and tightly connected with a cover equipped with neodymium magnets magnetically connected to contacting neodymium magnets of holders fixing COB LED modules equipped with COB LED diodes and lenses, and a cooling subassembly situated above it, including a cooling fan and a water radiator placed thereon and detachably connected thereto. Both components being connected to each other by two connecting pipe sets, such that the upper connector of the pipe set is screwed into the threaded opening of the water chamber of this water radiator.

A lighting fixture with transparent antennas and heat spreaders, including: conductive portions made with conductive materials, and non-conductive portions made with non-conductive materials; one or more free spaces, enclosed between said conductive portions and the non-conductive portions; one or more anchor points, positioned inside said free spaces, for fixing one or more mechanical adapters; one or more electricity supply interfaces, positioned inside said free spaces, for electrically powering the lighting fixture with an available power supply; a removable and optically transparent screen, including non-conductive elements, made with non-conductive materials, and conductive elements, made with conductive materials, the screen being equipped with optically transparent antennas, metallized through holes, optically transparent transmission lines and optically transparent heat spreaders; a metallic outer frame protecting the optically transparent screen in which are positioned radio frequency connectors and connected to the optically transparent screen and to the optically transparent transmission lines.

A system for upgrading and retrofitting existing streetlights. The system enables conventional streetlights using sodium vapor, and other conventional lighting technologies, to be upgraded to more energy efficient and long-lasting LED lighting. At the same time, cellular and wireless communications can be added to the streetlight to provide additional bandwidth over that provided by conventional cell towers. The system can offload bandwidth in otherwise overloaded areas, such as densely populated urban areas. The system can include mini- or micro-cellular routers, GPS, Wi-Fi, Bluetooth®, and other micro cellular and wireless technologies. The system can include a light fixture styled to look like existing conventional light fixtures and can be retrofitted to existing streetlight poles and mounts with little, or no, modification to the pole and wiring.
