Abstract
A lighting apparatus (102) for hazardous environments, comprising at least one substantially point-like source of light (4), and a housing structure for said at least one substantially point-like source of light, defining at least a triple barrier protective encapsulation (1, 3, 7) to seal and insulate said at least one source of light from the environment, wherein said triple barrier protective encapsulation is at least partially optically transmissive to enable light propagation from said at least one source of light to the environment at predefined wavelengths.
Claims22
A lighting apparatus for hazardous environments, comprising
- at least one substantially point-like source of light, and
- a housing structure for said at least one substantially point-like source of light, defining at least a triple barrier protective encapsulation,
- the at least triple barrier encapsulation comprising an outer tube, an inner tube, and a fully encapsulating core material element inside the inner tube to completely seal and insulate the at least one source of light and at least one of an electrical board and electrical contacts from the environment,
- wherein said triple barrier protective encapsulation is optically transmissive to enable light propagation from said at least one source of light to the environment at predefined wavelengths.
