Embodiment Construction

[0037] In industries such as chemical, oil and gas, the environment in enclosed spaces of buildings often becomes saturated with flammable and thus dangerous gases. For lighting purposes in such environments, flame resistant lighting is required. It is required that the flame be extinguished within the housing of the lighting device even if it is caused by arcs and sparks in the housing of the lighting device. Additionally, expensive, certified electrical connections that are properly sealed and provided with hermetic covers to prevent flame spread and pressure overlap need to be used to avoid any flame spread or pressure overlap.

[0038] The present disclosure contemplates a lighting device that obviates the above mentioned disadvantages of the arrangement as described above.

[0039] The lighting device of the present disclosure will now be described with reference to the accompanying drawings.

[0040] figure 1 is an isometric view of the lighting device 100 of the pres...

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.

Description

technical field [0001] The present disclosure relates to the field of lighting devices. Background technique [0002] The following background information herein is related to the present disclosure and is not necessarily prior art. [0003] Lighting devices or lamp packages are installed in closed spaces of residential and industrial buildings. These lighting fixtures are self-contained units comprising a light bulb (which may be an incandescent bulb or a compact fluorescent lamp) or an array of light-emitting diodes, where the light-emitting diodes are mounted with a driver. [0004] In industries such as chemical, oil and gas, the environment in enclosed spaces of buildings often becomes saturated with flammable and thus dangerous gases. Lighting devices generate heat during their operation. Thus, the gas trapped in the housing of the lighting device gradually heats up with the working time of the lighting device, so that the pressure in the housing of the lighting dev...
