Description

MODULAR DISPLAY light emitting

Description

The object of this patent of invention is a modular light emitting display specially designed for use as a lighting element in footages indoors or outdoors and as a decoration or use in applications architectural and stage lighting and having a conformation characteristics techniques, advantages and applications that improve substantially and significantly similar articles existing on the market and proposals developed in the prior art.

In the patent number P200600641 of the same applicant a transmitter flexible light especially applied to films for adjusting an individualized lighting to the socket is required, depending on the structural characteristics of the environment, adapting to it developed by varying the shape of the light emitting device and thus setting a transmitter flexible, capable of adapting to very small space and objects of various shapes, with faster and less intrusive in the spaces to illuminate illumination light. This light emitter is also characterized by great flexibility in the ability to change and precise electronic adjustment of the light emitted by the same, different parameters: luminous intensity, color temperature.

The invention presented in this new request is specified in forming the emitter aforementioned light, which is configured as a screen sheet structure articulated and reduced thickness, approximately about 50mm maximum consisting of a variable number and scaleable aluminum bars incorporating a number of light sources composed of units of LEDs and corresponding electrical circuitry, ie, a printed circuit incorporating aluminum LEDs and electronic accessories.

Specifically, the essential unity of the screen, defined as "basic unit" is constituted by a complex aluminum profile with preferably U-shaped as mechanical support functions heatsink. On each profile an aluminum plate incorporating the electrical tracks, various electronic components and other elements are inserted, the main element any number of sets of at least two LEDs and associated electronics being protected set by a cover aluminum.

The other key element of this technology is constituted by each set of LEDs preferably three, which is termed as "low emission unit" (UME), each of these units consists of the following elements:

3 high power LEDs and different carefully selected colors, one warm white (warm white), 1 cool white (cold white), one green (green), following a predefined spatial distribution. The selection of these LEDs with the high accuracy in the calibration of the mixture of the luminous fluxes are the keys to obtain the chromaticity and luminosity features described in this patent, so proceed to careful selection of BIN for each of the selected LEDs (BIN both color and luminous flux) and calibrated using spectroradiometer.

1 fresnel lens plastic specially designed for homogenising and mixing light of three LEDs and focusing at an angle of between 40 ° and 60 °.

1 Control and electronic MONITORING intensity of light emitted by each of the LEDs for the scale calibrated variable color temperature-related variable intensity and all with the value of color rendering index CRI highest possible throughout the spectrum.

1 power supply system and electronic control with a modulation higher than 18KHz so that the luminaire is free from flicker even with speeds of up to 160 camera images per second.

Referring to the number of sets of LEDs 5 is, minimum emission units that are part of the basic unit and the same LEDs are integrated in each minimum unit of emission, the number of each other may be variable depending on certain needs. In fact, the minimum number of LEDs to fully work the minimum unit is two, but it is understood that the preferred embodiment contemplates three LEDs, and also can settle a minimum emission unit with four or more LEDs. Similarly, the LEDs can be of various colors, but choosing the colors listed above appears to be the most appropriate to achieve the best results

In turn, the complex design of the aluminum profile is the basis of the proper dissipation of heat generated by the LEDs to ensure such operating conditions that allow a service life of 50,000 hours above luminaire.

The binding of the various modules forming the display is performed by electrical connections for power and signal, parts of mechanical connection with articulating and insulating functions of vibration, which allow attachment of how any given position.

The light emitting display includes a module or luminary external power control, color control and electronic control of light output by microprocessor programmed with firmware itself whose characteristics are developed in succeeding paragraphs of this specification.

When considering their technical, electrical characteristics and ability lighting is important to note that has a high light intensity, capable of overcoming 700Lux 3m away and a power consumption of less than 220W in configuration 6 Basic Units with 8 SMUs each . Each basic unit with 8 SMUs delivery over 00 Lux 3 meters with a color temperature of 5600K or more than 45 Lux 3 meters with a color temperature of 3200K, all with a lower consumption 4OW.

In the luminous aspect, they have a balanced temperature and color that varies from 3000K to 6900K. The variation be continuous scale calibrated and also calibrated steps. The electronic control module enables the intensity remains constant over the entire range of color temperature.

As the light intensity will be adjusted from 10 to 1 without changing color temperature, with continuous variation in calibrated scale and stepwise calibrated and controlled by the communications protocol DMX (Digital Multiplex) used to control stage lighting .

Likewise, the control module Output Maximin has the option to obtain the maximum light intensity for each color temperature. All these aspects characterize light emitting display as claimed perfectly balanced for use in filming and films with film cameras, video or picture set: it is free of flickering or synchronize the fliqueo to 50Hz or 60Hz; It has a color spectrum of light emitted adapted to the color space required by film cameras and video with a value of CRI ensures correct color reproduction; if emits any wave type, this will not distort the video signal or sound; It has a modulation frequency of higher than 18000Hz LEDs; It has a low or zero emitted less than 18dB noise level.

As to its physical structure, as the description made it clear, the light emitting screen is articulated, reduced thickness, less than 50mm, light (with a weight below 6kg kilos) and easy to transport. It is also characterized by fire retardant and its ability to be scalable in size, since its configuration allows binding modules and assembly of several mechanically and electronically equal units. The forming modules and the pivotability are issues that must be marked up because they define the structural configuration of this innovation, since each basic module is capable of being autonomous in itself, separating the both mechanically set or electronically and being operable independently. Moreover, this same pivotability allows to fix the screen in a rigid position, while being capable of allowing the coupling parts or auxiliary elements acting as visors and incorporate different attachment means to insert additional elements such as filters colors or other commonly used. Another important feature is the possibility of incorporating an element allowing their coupling in a standard tripod or the like, for example equivalent to a ball head in rear central position with a pin for coupling mechanism.

The articulated structure allows concentrating or open the light beam and varying the shape of the radiating surface. This large radiating surface, combined with the use of specially designed fresnel lenses and specific diffusers, emits a beam of perfectly smooth but directional.

Thus, the aluminum bars are a complex profile, specially designed U-shaped complex to perform the following functions: • evacuation of the heat produced by the LEDs

• to support both electronic and electrical elements such as the optical and mechanical

• allow anchoring of a large series of accessories such as side shields, connecting pins, ball joints, sailboats ...

• allow articulated and adjustable connection between an unspecified number of bars

As referenced above, each of the aluminum bars constitutes a basic unit, so that the sum of different modules forming the final screen according to the required dimensions.

The pivotability of the screen as claimed involves the incorporation of a silicone washer assembly and thyme a specific torque, which also allows to fix the display in a given position and to maintain stable and motionless time required.

In turn, the complex design of the aluminum profile is the basis of the proper dissipation of heat generated by the LEDs to ensure such operating conditions that allow a service life of 50,000 hours above luminaire. Another key element of the transmitter light screen is a protective outer layer, comprising a transparent plastic material and fireproof having function correction filter, homogenizer and guiding the light beams of different LEDs while allowing the front protection LEDs and internal components. Obviously, this station screen light or luminaire incorporates diodes, resistors and other basic and necessary electrical and electronic components for its operation, including a power source, whether to connect to the mains with the corresponding adapter unit to external current or by battery or any other means. As mentioned above, this modular light emitting display has the corresponding control module, which can be linked to the screen by wired or be connected thereto by other means, such as infrared signals or electromagnetic waves among others, so that changes and adjustments to the operation of the display can be done with a remote control.

This control module allows digital adjustment, can feed and manage from 1 to 8 basic units is a remote control with fíicker-free, ie technology it makes the light emitted by the screen does not produce recordable flickers by cameras film or video, also meets the regulations concerning electromagnetic interference, and has the option to control DMX (Digital multiplex).

Specifically, the characteristics, elements and functions that allows you to run this control module included the following:

• Color temperature variation. The digital display allows variation calibrated in increments of 100 ° K to 6900K 3000K from. The light intensity remains constant over the entire range of color temperature.

• Dimmer or regulating device light intensity. The digital display allows variation calibrated 10 to 1 of the luminous intensity keeping the temperature unaltered color.

• Output Maximin. It offers maximum light intensity for each color temperature

• Green / magenta correction. The software developed by the calibration performed by spectrophotometer for adjusting each LED ensures correct colorimetry in the light emitted by the luminaire. Calibration is performed in the laboratory according to current international standards of CIE 13.3-1995 for measuring the CRI and the chromaticity coordinates (x, y CIE 1931). This certifies that the fixtures do not have green / magenta deviation. The switch - / + GREEN allows, however, the color shift of the light emitted at any color temperature to green or magenta in steps of - / + 1/8 and 1/4. When this switch is out of the standard position a green LED lights up on the Control Unit as a warning that the light emitted does not guarantee the correct colorimetry. Technically the control module consists of:

• A power supply, specially selected for its low weight and low noise level, whose purpose is to convert the AC to DC and supplying a minimum 300W power. "3 digital displays 7-segment indicator settings color temperature and light intensity entered by the user.

• +/- 5 buttons for color temperature, light intensity and +/- maximum light output option.

• Switch 1 to regulate green / magenta deviation. • 1 LED indicator activation or not of the Maximin Output function.

• 1 LED activation indicator deviation green / magenta.

• EPROM memory to store the data entered by the user, so that they can always be recovered in the event of system shutdown.

• A micro controller unit responsible for receiving user input data and convert modulation values ​​at the output.

This unit has an internal program specially developed for this application with its own firmware. The micro controller unit includes as inputs the schedule data that the user enters into the system (color temperature, light intensity value, option enabled or not Maximum Output) and converts the power values ​​preset accurately by programming which supplies each of the three channels for feeding the three types of LEDs.

The accuracy of programming allows subdividing the power values ​​of each of the channels in 1024 steps. The specific power of each channel is managed by the micro controller using PWM (width modulation pulse) at a frequency of 20,000Hz to eliminate any possibility of flashing light emitted by the light, even at high recording speeds of cameras.

The accuracy of this programming and the correct assignment of the value of specific flow for each channel are a key to get high CRI index variation of the color temperature without changing the light intensity variation of the light intensity without alteration of the color temperature and obtaining maximum brightness possible for each color temperature with high energy efficiency.

According to the above, the light emitting display has a preprogrammed software that controls the electrical system described. This software is one of the key elements in the efficiency, durability hours LEDs, precise calibration of the mixture flow from each of the three LEDs composing the Low Emission Unit and the possibilities of variation of temperature Color and light intensity as a high color rendering value is maintained. In summary, this electronic control by CPU, along with a selection absolutely precise not only the three types of LEDs but also the BIN of each, the predefined spatial distribution, the use of fresnel lenses specially designed and application of plastic protective filter and diffuser are responsible for obtaining a luminaire comprising LEDs that meets the set of criteria:

• obtaining a high rate of reproduction and color suitable for use with still cameras, film and video.

• variable color temperature from 3000K calibrated to 6900K.

• Possibility to vary the light intensity (LUX) in a range of 10 to 1 in each of the color temperatures of the scale without changing the color temperature selected.

• Possibility of obtaining the maximum power for each color temperature scale.

• Obtaining a homogenous luminous flux without smearing color or discontinuities.

• Obtaining a stable flow for each of the LEDs it allows for a more than 50,000 hours lifespan current.

• High light intensity: 700 lux able to overcome 3m

• Low power consumption: less than 220W "Reduced thickness: 47mm each Basic Unit

• Ignition and instant electronic adjustment

• LED technology light without heat • High CRI to any color temperature

• articulated and modular design to adjust the angle and the beam shape

These drawings should be analyzed and considered only as an example and without any limiting or restrictive.
