  • 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.

  • Patent number: 10473318
    Abstract: An LED fixture (200) that facilitates effective heat dissipation of an array of LEDs, having improved thermal performance; and is easy to mount or dismount. The LED fixture (200) includes a heat sink (202) having a hollow configuration, and a plurality of fins (204) extending circumferentially and outwardly from the heat sink (202). The LED fixture (200) further comprises a base (206) configured at an operative bottom portion of the heat sink (202), and a driver housing (208) connected to an operative top surface of the heat sink (202). The base (206) is configured to support an array of LEDs. The driver housing (208) is configured to accommodate a plurality of LED drivers. The driver housing (208) and the base (206) are arranged in a spaced apart configuration.

  • Patent number: 10274170
    Abstract: The present disclosure relates to the field of luminaires. More specifically, the present disclosure envisages a drain arrangement for use with a luminaire that is supported on a wiring conduit via a junction box. The arrangement includes a hood coupled with the junction box via a connecting conduit, wherein connection cables from the wiring conduit are received within the hood via the connecting conduit and the junction box. An adaptor extends from the hood and the luminaire. The adaptor is defined by a sidewall extending from the luminaire and has an operative top surface configured on an operative top periphery of the sidewall. The adaptor further includes an annular inner sidewall configured to circumscribe an electric connection of the luminaire. A drain conduit extends from the adaptor and is configured to drain out the fluid collected within the adaptor outside of the annular inner sidewall.
