  • Patent number: 11022291
    Abstract: The utility model embodies a greenhouse hydro-cooled grow light LED system that administers a mist or vapor. This system operates in a range of temperatures, which are determined by the liquid temperature running through the channeled copper heatsink. The manipulation of the liquid's temperature produces the desired humidity. A brass high pressure liquid barbed valve fitting is secured on either side of the light housing, which is also connected to a humidity sensor electrical outlet. Low humidity closes the liquid valve. This allows a liquid pressure increase in all liquid lines, until the liquid release pressure of 60 psi is reached. The mist/vapor component is realized through the placement of high pressure mist nozzles. At release pressure, an atomized mist with droplets under 60 microns is outflowed.

  • Patent number: 10584836
    Abstract: The invention discloses a uniformly illuminating LED light strip, comprising an outer casing, an inner casing, and a light-emitting component, the outer casing comprises a light-transmitting layer and a reflective layer, the reflective layer is disposed on two sides of the light-transmitting layer and extends to the bottom of the light-transmitting layer, the light-transmitting layer is provided with a vacant part, the light emitted by the LED illuminant is refracted by the vacant part and then emitted through the light-exiting surface of the light-transmitting layer. In the present invention, the light of both large-angle and the small-angle emitted by the LED illuminant is reflected and refracted by the mutual cooperation of the vacant part and the reflective layer, and finally emitted through the light-exiting surface of the light-transmitting layer making the light of the light strip more uniform and improving the decoration and lighting effect of the light strip.

  • Patent number: 10571113
    Abstract: Embodiments disclosed herein describe systems and methods for heat sinks within light fixtures. In embodiments, the heat sink may be a passive system that creates a cross-flow thermal management system to dissipate large amounts of heat in a slim light fixture. Embodiments may utilize a series of wings assembled in a linear design that are positioned perpendicular to the length of the light fixture to preserve the cross-flow heat sink.

  • Patent number: 10535582
    Abstract: A semiconductor thermal-conductive heat sink structure includes a substrate and a thermal-conductive heat sink device. The substrate includes opposed upper and lower planes. A top conductive copper foil is provided on the upper plane to carry a semiconductor device. The thermal-conductive heat sink device includes at least one cooling fin and a high thermal-conductive rivet. A clearance is formed between the cooling fin and a thermal-conductive heat sink device socket or between two adjacent cooling fins such that greater cooling areas are available to the thermal-conductive heat sink device. With the thermal-conductive rivet joining the top conductive copper foil and the cooling fins, heat generated by the activated semiconductor device is quickly conducted through the rivet and dissipated from the greater cooling areas of the cooling fins to prevent malfunction of the semiconductor device attributed to heat accumulation induced by poor heat dissipation.

  • Patent number: 10480763
    Abstract: The present disclosure relates to the field of lighting systems. The collective dissipation of heat by various components of lighting systems, inside a conventional single compartment enclosure, raises the temperature of each of the components, resulting in damage and reduction in the life of the components. The present disclosure, therefore, envisages an enclosure for lighting systems which is compartmentalized, and prevents overheating of the components of the lighting systems. The enclosure includes a first compartment and a second compartment. At least one driver is receivable in the first compartment and at least one light emitting component is receivable in the second compartment. The first compartment is insulated from the second compartment. The enclosure is primarily used for lighting fixtures which require high efficiency operation from a compact package, or lighting fixtures which operate in rugged environments at high temperatures.
