  • Patent number: 11022287
    Abstract: The present disclosure envisages a luminaire (100). The luminaire (100) comprises at least an array of light-emitting diodes (10), a driver (20) for driving the array of light-emitting diodes (10), a first compartment (30), a second compartment (40), a perforated wall (50), an array of fins (60) and a lid (70). The first compartment (30) houses the array of light-emitting diodes (10). The second compartment houses the driver (20). The second compartment (40) is separated from the first compartment (30) by a perforated wall (50). The array of fins (60) is disposed on an operative external wall surface surrounding the first compartment (30) and/or the second compartment (40) of the luminaire (100). The lid (70) is removably fitted on an operative end of the first compartment (30). The luminaire (100) has an explosion-proof construction, dissipates heat efficiently, is less expensive and is easy to assemble.

  • 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.
