No son conocidas por el solicitante luminarias que ofrezcan dos tipos de iluminación, y además permitan escoger, mediante sencillos cambios en la estructura de la luminaria, los dos tipos de iluminación que ofrece.Luminaries are not known to the applicant that offer two types of lighting, and also allow you to choose, through simple changes in the structure of the luminaire, the Two types of lighting it offers.
La luminaria descrita en esta memoria dispone de una estructura sencilla que permite lograr cualquier tipo de iluminación por medio de sencillos ajustes en la estructura de la luminaria.The luminaire described in this report has a simple structure that allows to achieve any type of lighting by means of simple adjustments in the structure of the luminary.
La luminaria está constituida a partir de dos fuentes luminosas distanciadas generalmente sobre un plano vertical, estando una por encima de la otra, que disponen entre medias de un medio difusor-reflector en posición oblicua entre ambas, y que es enfocado por ambas fuentes luminosas.The luminaire is made up of two light sources generally distanced on a plane vertical, being one above the other, which have between means of a diffuser-reflector medium in position oblique between both, and that is focused by both sources bright.
Mediante la luminaria de la invención se logra una alta variabilidad en los niveles y tipos de iluminación ofrecidos utilizando un único modelo de luminaria.The luminaire of the invention achieves high variability in lighting levels and types offered using a single luminaire model.
Una primera fuente luminosa- está dispuesta en el lado accesible desde la estancia de la luminaria, mientras que una segunda fuente luminosa se encuentra tapada por el medio difusor-reflector, que impide que un usuario situado en la estancia pueda alcanzarla.A first light source - is arranged in the accessible side from the luminaire's room, while a second light source is covered by the middle diffuser-reflector, which prevents a user located in the room can reach it.
La luz emitida por la primera fuente luminosa es reflejada en gran parte para iluminar la estancia, permitiendo así la utilización de la luminaria para alumbrar actividades visuales.The light emitted by the first light source is reflected largely to illuminate the room, thus allowing the use of the luminaire to illuminate activities visual
La luz emitida por la segunda fuente luminosa ha de ser transmitida por el medio difusor-reflector para poder ser utilizada por un usuario de la estancia. Como el factor de transmisión del medio difusor-reflector es bastante más reducido que el factor de reflexión, el nivel de iluminación ofrecido es más pequeño, alcanzándose una iluminación de vigilancia.The light emitted by the second light source has if transmitted by the diffuser-reflector medium to be used by a user of the stay. As the transmission factor of the diffuser-reflector medium is much smaller than the reflection factor, the level of lighting offered is smaller, reaching lighting of vigilance.
Cuando esta segunda fuente luminosa está alimentada por una batería de emergencia que se activa cuando existe corte del suministro eléctrico, se produce un alumbrado de emergencia. Se puede conectar esta batería a la primera fuente luminosa, alcanzándose mayores niveles luminosos.When this second light source is powered by an emergency battery that is activated when there is a power cut, lighting of emergency. This battery can be connected to the first source bright, reaching higher luminous levels.
El medio difusor-receptor estará constituido por diferentes materiales según el tipo de fuente luminosa que se utilice. Si ambas fuentes luminosas son frías, como pueden ser tubos fluorescentes o LEDs, el medio difusor-receptor estará constituido por una lámina de metacrilato opalino o policarbonato, a la cual se le adhiere una lámina de poliéster de espesor entre 0,02 mm y 0,1 mm para lograr que las propiedades ópticas sean aproximadamente:The diffuser-receiver medium will be constituted by different materials according to the type of source Luminous to be used. If both light sources are cold, such as fluorescent tubes or LEDs, the medium diffuser-receiver will consist of a sheet opal methacrylate or polycarbonate, to which it adheres a polyester sheet with a thickness between 0.02 mm and 0.1 mm for ensure that the optical properties are approximately:
\newpage\ newpage
Si, por el contrario, las fuentes luminosas son calientes, como fuentes incandescentes, halógenos o halogenuros metálicos, el medio difusor-reflector habrá de ser un vidrio resistente a la temperatura (del tipo de los borosilicatos o similar) o un vidrio templado, con un tratamiento de arenado o acidado, y una deposición metálica mediante la técnica de spattering, de aluminio, plata u otro metal conveniente, para lograr las siguientes características ópticas:If, on the contrary, the light sources are hot, such as incandescent, halogen or halide sources metallic, the diffuser-reflector medium must be a temperature resistant glass (of the type of borosilicates or similar) or a tempered glass, with a treatment sandblasting or acidity, and a metal deposition by technique Spattering, aluminum, silver or other convenient metal, for achieve the following optical characteristics:
Se puede lograr una iluminación estética mediante la colocación de filtros de colores entre las fuentes luminosas y el medio difusor-reflector, o haciendo que este medio difusor-reflector disponga de su propio filtro o simule una vidriera.Aesthetic lighting can be achieved through the placement of color filters between light sources and the diffuser-reflector medium, or making this diffuser-reflector medium have its own filter or simulate a stained glass window.
La luminaria se encaja en una pared sobresaliendo únicamente un marco que asegura la sujeción de los distintos elementos, a la vez que disimula imperfecciones en los bordes de la pared en contacto con la luminaria.The luminaire fits into a wall protruding only a framework that ensures the subjection of the different elements, while concealing imperfections at the edges of the wall in contact with the luminaire.
Para la protección de las fuentes luminosas, se sitúa un vidrio protector en la boca de, al menos, la primera fuente luminosa por ser más accesible al público, que además realiza parte de la difusión de la luz emitida por la fuente. Si la primera fuente luminosa es fría, se puede sustituir el vidrio por un material polimérico como el policarbonato o metacrilato, siempre que su factor de transmisión sea elevado.For the protection of light sources, place a protective glass in the mouth of at least the first light source for being more accessible to the public, which also performs part of the diffusion of the light emitted by the source. If the first light source is cold, you can replace the glass with a polymeric material such as polycarbonate or methacrylate, always that its transmission factor is high.
