Definitions
- the present invention refers to a built-in lighting device, of the type that includes a built-in body provided with an internal cavity intended to house lighting means and a front plate of translucent material for the passage of light outward.
- Recessed lighting devices intended to be embedded in the floor or on a wall, generally comprise a metal body of tubular configuration that defines an interior cavity for the accommodation of the lighting means and, externally, a perimeter thickening that forms an embedment stop. of the mentioned tubular body on the ground or on the surface in question.
- the tubular body is closed at the front end by means of a front plate made of translucent material through which the light generated by the lighting elements is projected outwards.
- This plate of translucent material is generally made of glass and its mounting on the tubular body requires the use of special glues and sealing gaskets that ensure, on the one hand, its correct fixing and, on the other hand, the necessary sealing to prevent the Water and moisture access the lighting elements housed inside the device.
- the interior cavity is separated from the exterior only by the aforementioned glass plate.
- the interior cavity is left without any protection and communicated with the exterior, which raises problems of different kinds, including: the possibility of access and humidity to the interior chamber that houses the elements lighting systems and the risk of electrocution accidents in the event that a person places their fingers or a piece of conductive material in the cavity that houses the lighting elements.
- the access of the cables of Feeding to the interior cavity is generally carried out through the mouth defined at the rear end of the recessed body, without including the necessary elements to prevent access of water or moisture to the lighting device through said rear end.
- the recessed lighting device object of the present invention has a series of constructive features aimed at ensuring the watertightness of the interior cavity that houses the lighting means, to prevent frontal access to said cavity, even in the case of that the protection front plate is broken and to provide additional protection of the lighting means against ultraviolet rays.
- the recessed body is made of a translucent material of high resistance and that has a general tubular configuration provided with an internal transverse wall that separates the posterior cavity intended to house the lighting means of an anterior cavity that houses the translucent front plate and that is defined when injecting, around said translucent front plate, the material intended to form the recessed body.
- the built-in body being made of a high resistance translucent material, allows the light generated by the lighting means to pass through the transverse wall that separates the posterior cavity from the anterior cavity, in which the translucent front plate is housed.
- This transverse wall acts as a barrier in the event that the translucent front plate breaks, preventing both the access of water or. of humidity to the posterior cavity, such as the introduction into said posterior cavity of the fingers or metallic elements, therefore eliminating the risk of electrocution.
- the rear cavity has a rear access mouth, provided with an internal thread for mounting a closing cover and the corresponding sealing gasket, said cover presenting a threaded hole for mounting a sealing gasket. sealing and a cable gland integral to a tube through which the electrical supply cables of the lighting means access the interior cavity.
- the device of the invention further comprises an embellishing ring made of opaque material intended to cover the front area of the recessed device, except in the location area of the translucent front plate. Given the translucent nature of the material that makes up the recessed body, this plate prevents light from emerging laterally through the material that forms the perimeter thickening or embedment stop.
- the translucent material front plate has on its lateral surface at least one perimeter recess for accommodating a part of the material that makes up the recessed body during its shaping. This perimeter recess prevents the front plate from being removed from the recessed body, ensuring its final fixation without using special glues or other similar substances.
- the front plate can be made of tempered glass or polycarbonate and that the front body is made of polycarbonate or another translucent high resistance substance with ultraviolet protection.
- This ultraviolet protection allows the transverse wall to prevent accelerated deterioration of the lighting elements when the recessed device is installed in an area that is directly affected by sunlight.
- the recessed lighting device comprises a recessed body (1) of polycarbonate with ultraviolet protection, which has a general tubular configuration and which has internally of a transverse wall (11) that separates the posterior cavity (12), intended to contain the lighting elements (3), from the anterior cavity (13) in which a translucent tempered glass plate (2) is inserted or polycarbonate.
- the aforementioned cavity (13) is defined by injecting the polycarbonate that makes up the recessed body (1) around the translucent plate (2).
- This translucent plate (2) has a perimeter recess (21) in which a part of the material forming the recessed body (1) is housed, ensuring the final immobilization of the translucent plate (2) with respect to the recessed body (1).
- the recessed body (1) has an outer perimeter thickness (14) constituting an embedment stop and, in the rear cavity (12), an internal thread (15) for mounting the rear cover (4), with the corresponding gasket sealing (41).
- the rear cover (4) is provided with a threaded hole (42) for mounting the corrugated tube (5) through which the power supply cables (6) of the lighting elements (6) access the rear cavity (12). 3).
- the assembly of the corrugated tube (5) on the threaded hole (42) of the cover is carried out by means of a gland (51) integral with the mentioned tube (5), and charged with pressing the sealing gasket (52) against the cover posterior (4).
- This recessed device also includes an embellishing ring (7) of opaque material that frontally covers the perimeter thickening or embedment stop (14), the light generated by the lighting elements (3) leaving through the transverse wall (11) and of the translucent plate (2).
