Watertight seal lighting equipment

Abstract

A watertight seal lighting equipment, used in particular for the lighting of watertight and anticorrosive environments, comprises a main body (10) made of sheet iron, moulded in a single piece, a closing screen (11), obtained from a flat slab of tempered glass, a closing head (12), moulded by die-casting of aluminium and sealed to the body (10) and the screen (11), and a movable and openable head (13), suitable to allow the extraction from the body (10) of a extractable plate or support element (14), on which the light sources and the feeder of the equipment are wired. Since the movable head (13) is the only opening between the outside and the inside, the seal results extremely improved, compared to the traditional equipment, because the silicone seal gasket (17) has a length lower than that one of the traditional equipment, and the rigidity of the movable head (13) offers an uniform pressure on the silicone gasket (17), unlike what happens in the traditional equipment.

Description

technical field [0001] The present invention generally relates to a waterproof sealed lighting device. [0002] In particular, the present invention relates to a pre-assembled lighting pendant for use in a waterproof and anti-corrosion environment. [0003] The chandelier used in a waterproof and anti-corrosion environment is a lighting device with a typical IP65 protection level, which is made of plastic or metal as a whole, and uses T5 or T8 fluorescent lamps. Background technique [0004] Pendant lights of the traditional type have a protective partition made of plastic or molded or tempered glass panels; alternatively, they can use flux recyclers (reflectors) made of polished aluminum or metallized plastic . [0005] Typically, protection against penetrating liquids or fluids is achieved by a gasket, which is positioned between the plastic structure or body and the bulkhead, and held in place by perimeter closure hooks. [0006] The light sources for these luminaires ...

AI Technical Summary

Problems solved by technology

[0007] The closing hooks (there are 8-10 in each lighting device) then distribute the pressure on the gasket in an irregular manner, which, in addition, during the usual implementation, deposits dirt, oil, etc., Therefore, this makes the cleaning work necessary to maintain the lighting installation difficult

Whenever access to the interior of the unit is required due to routine maintenance (e.g. replacing a broken fluorescent lamp), the gasket will always be squeezed, risking breaking the seal of the unit
