DISPOSITIVO DE ILUMINACIÓN PARA ALUMBRADO DESCRIPCIÓN  LIGHTING DEVICE FOR LIGHTING DESCRIPTION
Dispositivo de iluminación para alumbrado Lighting device for lighting
Objeto de la invención Object of the invention
La presente invención tiene por objeto un dispositivo de iluminación para alumbrado, que gracias a una serie de elementos dispuestos en su estructura interna, consigue una refrigeración forzada en su interior, eliminando los problemas de calentamiento de los dispositivos de iluminación actuales. Antecedentes de la invención The present invention aims at a lighting device for lighting, which thanks to a series of elements arranged in its internal structure, achieves forced cooling inside, eliminating the heating problems of the current lighting devices. Background of the invention
Por ley, los dispositivos de iluminación para alumbrado deben ir debidamente protegidos en su interior. Esto genera grandes problemas de calentamiento en el cabezal, pues los equipos luminarios interiores están encendidos gran cantidad de tiempo, calentando en exceso dicho cabezal. By law, lighting lighting devices must be properly protected inside. This causes major heating problems in the head, since the interior lighting equipment is on a large amount of time, overheating said head.
Los equipos luminarios, del tipo que sean, quedan en el interior sin ventilación, calentándose en exceso, protegidos a través de difusores y con tapas superiores e inferiores. La temperatura se consigue disminuir cuando el equipo luminario que se dispone se materializa en LEDs, pero aun así es un parche al problema, sin solución definitiva, pues sigue calentándose en exceso, aunque menos que los primeros, disminuyendo la vida del equipo, pues el equipo sigue cerrado y provoca que se caliente. Descripción de la invención The luminaire equipment, of whatever type, is left without ventilation, overheating, protected through diffusers and with upper and lower covers. The temperature is reduced when the lighting equipment that is available is materialized in LEDs, but it is still a patch to the problem, with no definitive solution, because it continues to overheat, although less than the first, decreasing the life of the equipment, as the equipment remains closed and causes it to warm up. Description of the invention
La invención propuesta consiste en un dispositivo de iluminación para alumbrado, que presenta grandes ventajas respecto a los actualmente existentes en el estado de la técnica. Se trata de un dispositivo de iluminación, del tipo de los dispuestos en cascos urbanos, parques y otros. Dicho dispositivo de iluminación puede ser de soporte lateral de brazo, de columna de sustentación o cualquier otro, y poseerá medios para su fijación a pared o suelo. Al igual otros dispositivos de iluminación conocidos, el dispositivo de iluminación de la invención comprende un cabezal de alumbrado, de cualquier tipo, preferentemente con una pluralidad de caras, y con un equipo luminario en su interior. Por ley, cada una de las caras del cabezal ha de ir protegida, por lo que generalmente se disponen cristales transparentes o similares. Esto hace que se genere el problema del aumento la temperatura interna del cabezal, pudiendo llegar a producirse una explosión interna. Para eliminar este problema de calentamiento, en la presente invención se disponen una serie de elementos que en combinación, generan un refrigeración forzada en el interior del cabezal, haciendo circular el aire frío desde la parte inferior del cabezal hacia la parte superior, y provocando un efecto convección que obliga al aire a dar una especie de rodeo en el interior del cabezal, bajando de este modo la temperatura. The proposed invention consists of a lighting device for lighting, which has great advantages over those currently existing in the state of the art. It is a lighting device, the type of those arranged in urban areas, parks and others. Said lighting device can be of lateral support of arm, of column of support or any other, and will possess means for its fixation to wall or floor. Like other known lighting devices, the lighting device of the invention comprises a lighting head, of any type, preferably with a plurality of faces, and with lighting equipment inside. By law, each of the faces of the head must be protected, so that transparent or similar crystals are generally arranged. This causes the problem of increasing the internal temperature of the head to be generated, and an internal explosion may occur. To eliminate this heating problem, a series of elements are arranged in the present invention which, in combination, generate forced cooling inside the head, circulating the cold air from the bottom of the head towards the top, and causing a convection effect that forces the air to give a kind of detour inside the head, thus lowering the temperature.
Por lo general, los cabezales de iluminación disponen de una tapa superior cerrada y una placa inferior también cerrada, protegiendo el interior del equipo. Todas las caras laterales del cabezal han de ir protegidas, disponiendo cada una de ellas de un difusor. De acuerdo a la presente invención, el cabezal del dispositivo de iluminación dispone de la placa citada, pero provista de un pequeño canal por el que entrará el aire frío del exterior, mientras que para la salida del aire, la tapa dispone de un sistema de ventilación, que pueden materializarse en una pluralidad de orificios, protegidos contra la lluvia, viento y otros. En el interior del cabezal se dispone además el equipo luminario sobre una placa soporte, y bajo esta placa soporte y sobre la placa, y concretamente, sobre el canal practicado en dicha placa, se dispone un elemento con dos ramales paralelos y un ramal de unión, siendo el ramal superior mayor que el inferior, y disponiendo en el ramal inferior menor de una pluralidad de orificios de diferentes diámetros. Con esto se consigue que al atravesar el aire por el canal, forzando a pasar por él, y luego pasando por los orificios de distinto diámetro, provocar un efecto convección de el aire frío que atraviesa de abajo a arriba el cabezal, pasando a través de la placa soporte provista también de orificios de paso del aire, disminuyendo la temperatura del cabezal, y saliendo el aire por la parte superior a través del sistema de ventilación incluido en la tapa del cabezal, generalmente, a través de una pluralidad de orificios. In general, the lighting heads have a closed top cover and a bottom plate also closed, protecting the inside of the equipment. All the lateral faces of the head must be protected, each one having a diffuser. According to the present invention, the head of the lighting device has the aforementioned plate, but provided with a small channel through which cold air from outside will enter, while for the air outlet, the cover has a system of ventilation, which can materialize in a plurality of holes, protected against rain, wind and others. Inside the head the lighting equipment is also arranged on a support plate, and under this support plate and on the plate, and specifically, on the channel practiced in said plate, an element with two parallel branches and a connecting branch is arranged , the upper branch being larger than the lower one, and having in the lower branch smaller a plurality of holes of different diameters. With this it is achieved that when the air passes through the channel, forcing it to pass through it, and then passing through the holes of different diameter, causing a convection effect of the cold air that crosses the head from bottom to top, passing through The support plate also provided with air passage holes, decreasing the temperature of the head, and the air coming out from the top through the ventilation system included in the head cover, generally, through a plurality of holes.
