La conformación en módulos y la capacidad de articulación son aspectos que deben ser remarcados pues definen la configuración estructural de esta innovación, ya que cada módulo básico es susceptible de ser autónomo en sí mismo, separándose del conjunto tanto mecánica como electrónicamente y siendo capaz de funcionar de modo independiente. Por otra parte, esta misma capacidad de articulación permite fijar la pantalla en una posición rígida, al tiempo que es susceptible de permitir el acople de piezas o elementos auxiliares que actúen como viseras y de incorporar distintos medios de fijación para insertar elementos adicionales como filtros de colores u otros de uso habitual. Otra característica importante es la posibilidad de incorporar un elemento que permita su acople en un trípode estándar o similar, por ejemplo un mecanismo equivalente a una rótula de bola en posición central trasera con una espiga para el acople.As for its physical structure, as the description made, the light emitting screen is articulated, of reduced thickness, less than 50mm, light (weighing less than 6kg kilos) and easy to transport. It is also characterized by being flame retardant and its ability to be scalable in sizes, since its configuration in modules allows the union and assembly of several equal units both mechanically and electronically. The conformation in modules and the articulation capacity are aspects that must be highlighted as they define the structural configuration of this innovation, since each basic module is capable of being autonomous in itself, separating itself from the assembly both mechanically and electronically and being able to function independently. On the other hand, this same articulation capacity allows to fix the screen in a rigid position, at the same time that it is capable of allowing the coupling of parts or auxiliary elements that act as visors and to incorporate different fixing means to insert additional elements such as filters of colors or others of habitual use. Another important feature is the possibility of incorporating an element that allows its coupling on a standard or similar tripod, for example a mechanism equivalent to a ball joint in the central rear position with a pin for coupling.
La estructura articulada permite concentrar o abrir el haz de luz y variar la forma de la superficie radiante. Esta amplia superficie radiante, combinada con el uso de las lentes fresnel especialmente diseñadas y de los difusores específicos, emite un haz de luz suave pero perfectamente direccional.The articulated structure allows you to concentrate or open the light beam and vary the shape of the radiant surface. This large radiant surface, combined with the use of specially designed fresnel lenses and specific diffusers, emits a soft but perfectly directional beam of light.
Así pues, las barras de aluminio constituyen un perfil complejo, especialmente diseñado con forma de U compleja para ejercer las siguientes funciones:
• evacuación del calor producido por los LEDsThus, aluminum bars constitute a complex profile, specially designed with a complex U shape to perform the following functions: • evacuation of heat produced by LEDs
• hacer de soporte tanto a los elementos electrónicos y eléctricos como a los ópticos y mecánicos• support both electronic and electrical elements as well as optical and mechanical elements
• permitir el anclaje de una gran serie de accesorios como viseras laterales, espigas de unión, rótulas, veleros ...• allow the anchoring of a large series of accessories such as side visors, connecting pins, ball joints, sailboats ...
• permitir la unión articulada y regulable entre un número indeterminado de barras• allow articulated and adjustable connection between an indeterminate number of bars
Tal y como se ha referenciado anteriormente, cada una de las barras de aluminio constituye una Unidad Básica, de manera que la suma de distintos módulos conforma la pantalla final de acuerdo con las dimensiones necesarias.As previously mentioned, each of the aluminum bars constitutes a Basic Unit, so that the sum of different modules forms the final screen according to the necessary dimensions.
La capacidad de articulación de la pantalla que se reivindica conlleva la incorporación de un conjunto de arandela de silicona y tomillo con un par de apriete específico, el cual permite igualmente fijar la pantalla en una posición determinada y mantenerla estable e inmóvil el tiempo necesario.The capacity of articulation of the screen that is claimed entails the incorporation of a set of silicone washer and thyme with a specific tightening torque, which also allows to fix the screen in a certain position and keep it stable and immobile for the necessary time.
A su vez el diseño complejo del perfil de aluminio es la base de la correcta disipación del calor generado por los LEDs para garantizar unas condiciones de funcionamiento tales que permiten una vida útil de la luminaria superior a las 50.000 horas. Otro elemento fundamental de la pantalla emisora de luz es una capa exterior de protección, conformada por un material plástico transparente e ignifugo que tiene función de filtro corrector, homogeneizador y orientador de los haces de luz de los diferentes LEDs y a la vez permite la protección frontal de los LEDs y componentes internos. Evidentemente, esta pantalla emisora de luz o luminaria incorpora los diodos, resistencias y demás componentes eléctricos y electrónicos básicos y necesarios para su funcionamiento, incluyendo una fuente de alimentación, sea para conectarse a la red eléctrica con la correspondiente unidad adaptadora a corriente externa o bien mediante batería o cualquier otro medio. Tal y como se ha mencionado anteriormente, esta pantalla modular emisora de luz dispone del correspondiente módulo de control, el cual puede estar vinculado a la pantalla mediante cableado o bien estar conectado a la misma por otros medios, como pueden ser señales infrarrojas u ondas electromagnéticas, entre otros, de manera que los
cambios y ajustes en el funcionamiento de la pantalla puedan hacerse con un mando a distancia.At the same time, the complex design of the aluminum profile is the basis of the correct dissipation of the heat generated by the LEDs to guarantee operating conditions such that they allow a luminaire life of more than 50,000 hours. Another fundamental element of the light emitting screen is an outer layer of protection, consisting of a transparent and fireproof plastic material that has the function of a corrective filter, homogenizer and orientation of the light beams of the different LEDs and at the same time allows frontal protection of the LEDs and internal components. Obviously, this light emitting screen or luminaire incorporates the diodes, resistors and other basic electrical and electronic components necessary for its operation, including a power supply, either to connect to the mains with the corresponding external current adapter unit or by battery or any other means. As mentioned above, this modular light emitting screen has the corresponding control module, which can be linked to the screen by wiring or connected to it by other means, such as infrared signals or electromagnetic waves , among others, so that Changes and adjustments in the operation of the screen can be made with a remote control.
Este módulo de control permite realizar ajustes digitales, puede alimentar y gestionar desde 1 hasta 8 Unidades Básicas, es un Control remoto con la tecnología fíicker-free, es decir, hace que la luz emitida por la pantalla no produzca parpadeos registrables por las cámaras de cine o video, así mismo cumple las normativas en cuanto a interferencias electromagnéticas, y dispone de la opción de control por DMX (Digital MultipleX).This control module allows digital adjustments to be made, can power and manage from 1 to 8 Basic Units, it is a Remote Control with the ficker-free technology, that is, it makes the light emitted by the screen not produce recordable flickers by the cameras of cinema or video, also complies with regulations regarding electromagnetic interference, and has the option of control by DMX (Digital MultipleX).
En concreto, entre las características, elementos y funciones que permite ejecutar este módulo de control cabe señalar los siguientes:Specifically, among the features, elements and functions that allow this control module to be executed, the following should be noted:
• Variación de Temperatura de Color. El display digital permite la variación calibrada en pasos de 100° K desde 3000K hasta 6900K. La intensidad lumínica permanece constante en todo el rango de temperatura de color.• Color temperature variation. The digital display allows the variation calibrated in steps of 100 ° K from 3000K to 6900K. The light intensity remains constant throughout the entire color temperature range.
• Dimmer o dispositivo regulador de la intensidad lumínica. El display digital permite la variación calibrada 10 a 1 de la intensidad luminosa manteniendo la temperatura de color inalterada.• Dimmer or light intensity regulating device. The digital display allows the 10 to 1 calibrated variation of the light intensity keeping the color temperature unchanged.
• Máximum Output. Ofrece la máxima intensidad luminosa para cada temperatura de color• Maximum Output. Offers maximum light intensity for each color temperature
• Corrección verde/magenta. El software desarrollado según la calibración realizada mediante espectrofotómetro para el ajuste de cada uno de los LED garantiza la correcta colorimetría en la luz emitida por la luminaria. La calibración se realiza en laboratorio según los estándares internacionales actuales de CIE 13.3-1995 para la medición del CRI y de las coordenadas cromáticas (x, y CIE- 1931). Esto certifica que las luminarias no tienen desviación verde/magenta. El conmutador -/+ GREEN permite, no obstante, desviar el color de la luz emitida en cualquier temperatura de color hacia verde o magenta en pasos de -/+ 1/8 y 1/4. Cuando este conmutador está fuera de la posición estándar se enciende un LED verde en la Control Unit como aviso de que la luz emitida ya no garantiza la correcta colorimetría.
Técnicamente el módulo de control está constituido por:• Green / magenta correction. The software developed according to the calibration performed by spectrophotometer for the adjustment of each LED guarantees the correct colorimetry in the light emitted by the luminaire. The calibration is performed in the laboratory according to the current international standards of CIE 13.3-1995 for the measurement of CRI and chromatic coordinates (x, and CIE-1931). This certifies that the luminaires have no green / magenta deviation. The - / + GREEN switch allows, however, to divert the color of the light emitted at any color temperature to green or magenta in steps of - / + 1/8 and 1/4. When this switch is outside the standard position, a green LED on the Control Unit lights up as a warning that the emitted light no longer guarantees the correct colorimetry. Technically, the control module consists of:
• Una fuente de alimentación, especialmente seleccionada por su bajo peso y bajo nivel sonoro, cuya finalidad es convertir la corriente alterna en continua y suministrar un mínimo de 300W de potencia. » 3 displays digitales de 7 segmentos indicadores de los ajustes de temperatura de color e intensidad luminosa introducidos por el usuario.• A power supply, specially selected for its low weight and low noise level, whose purpose is to convert alternating current into continuous and supply a minimum of 300W of power. »3 7-segment digital displays indicating the color temperature and light intensity settings entered by the user.
• 5 pulsadores para +/- temperatura de color, +/- intensidad luminosa y opción de máxima potencia luminosa.• 5 push buttons for +/- color temperature, +/- light intensity and maximum light output option.
• 1 conmutador para regular la desviación verde/magenta. • 1 led indicador de activación o no de la función Máximum Output.• 1 switch to regulate the green / magenta deviation. • 1 LED indicating the activation or not of the Maximum Output function.
• 1 led indicador de activación de la desviación a verde/magenta.• 1 led indicator of activation of the deviation to green / magenta.
• Una memoria Eprom para guardar los datos introducidos por el usuario, de forma que puedan ser siempre recuperados en caso de apagado del sistema.• An Eprom memory to save the data entered by the user, so that they can always be recovered in case of system shutdown.
• Una unidad micro controladora encargada de recibir los datos de entrada del usuario y convertirlos en valores de modulación a la salida.• A micro controller unit responsible for receiving user input data and converting it into modulation values at the output.
Esta unidad posee un programa interno desarrollado especialmente para esta aplicación con firmware propio. La unidad micro controladora recoge como entradas los datos de programación que el usuario introduce en el sistema (temperatura de color, valor de intensidad luminosa, opción activada o no de Máximum Output) y los convierte en los valores de potencia preestablecidos con precisión por la programación, que suministra a cada uno de los 3 canales para alimentación de los 3 tipos de LEDs.This unit has an internal program specially developed for this application with its own firmware. The microcontroller unit collects as input the programming data that the user enters into the system (color temperature, light intensity value, option activated or not of Maximum Output) and converts them into the pre-set power values precisely by programming , which supplies each of the 3 channels to power the 3 types of LEDs.
La precisión de la programación permite subdividir los valores de alimentación de cada uno de los canales en 1024 pasos. La alimentación específica de cada canal es gestionada por el micro controlador mediante modulación PWM (modulación de ancho de pulso) a una frecuencia de 20.000Hz para eliminar toda posibilidad de parpadeo de la luz emitida por la luminaria, incluso a altas velocidades de grabación de las cámaras.The precision of the programming allows to subdivide the feeding values of each one of the channels in 1024 steps. The specific power supply of each channel is managed by the microcontroller by means of PWM modulation (pulse width modulation) at a frequency of 20,000Hz to eliminate any possibility of flickering of the light emitted by the luminaire, even at high recording speeds. cameras
La precisión de esta programación y la correcta asignación del valor de flujo específico para cada canal son una de las claves para conseguir el alto índice CRI, la variación de la temperatura de color sin alteración de la intensidad luminosa, la variación de la intensidad luminosa sin alteración de la temperatura de color y la
obtención de la máxima intensidad luminosa posible para cada temperatura de color con elevada eficiencia energética.The accuracy of this programming and the correct assignment of the specific flow value for each channel are one of the keys to achieve the high CRI index, the variation of the color temperature without alteration of the light intensity, the variation of the light intensity without alteration of the color temperature and the obtaining the maximum possible light intensity for each color temperature with high energy efficiency.
De acuerdo con lo anteriormente mencionado, la pantalla emisora de luz dispone de un software preprogramado que controla el sistema eléctrico descrito. Este software resulta ser uno de los elementos clave en la eficiencia, durabilidad en horas de los LEDs, calibración precisa de la mezcla del flujo de cada uno de los 3 LEDs que componen la Unidad Mínima de Emisión y de las posibilidades de variación de temperatura de color e intensidad luminosa mientras se mantiene un alto valor de reproducción cromática. En resumen, este control electrónico mediante CPU, junto con una selección absolutamente precisa no solo de los 3 tipos de LEDs sino también del BIN de cada uno de ellos, la distribución espacial predefinida, el uso de las lentes fresnel especialmente diseñadas y la aplicación del filtro de material plástico protector y difusor son los responsables de obtener una luminaria compuesta por LEDs que cumple el conjunto de características descritas:In accordance with the aforementioned, the light emitting screen has a preprogrammed software that controls the electrical system described.
