Description

Multimedia lighting system and spotlight necessary.

Object of the invention

The object of the present invention is a system of multimedia lighting and the focus used on it, characterizing each of the foci the fact of using as lighting medium a set of LEDs of different colors whose lighting is done from an own control electronics housed in each of the foci.

On the other hand the lighting system multimedia, in addition to having a series of spotlights, is designed and thought in a way that allows the government and control of the lighting of the different LEDs depending on their color.

Characterizes the present invention, the versatility offered in lighting each of the lights of individually, since control of each group is achieved of colors that the LEDs present, being able to achieve a control individualized of each one of the LEDs that each one has focus.

Thanks to the individual control of the effects of lighting in color, intensity, uniformity etc, in each of the spotlights, and their control performance combined with the rest of the foci achieves great versatility in the systems illumination.

In general these lighting systems are designed for operation in combination with others audiovisual effects, as well as aquatic sources, so They are called multimedia.

It also characterizes the present invention, the one that the lights used in the lighting system are waterproof, making them especially suitable for application in ornamental and similar sources, and in multimedia sets.

Therefore, the present invention is circumscribes within the scope of multimedia systems and particular form of among the lighting means used in such multimedia shows, well used individually or combined with other effects.

Background of the invention

So far the means used for the lighting are based on the use of spotlights that have lamps traditional, halogen or incandescent, in general all those that have a quick on in response to a signal external ignition.

Some records that describe, well systems multimedia are, for example, the Spanish Utility model, whose Publication number is ES 1051811U, which describes a cybernetic source in which the lighting medium used is a sealed lamp.

In the Spanish Utility model, the number of Publication ES 1058297 shows a sealed halogen bulb.

In the addition ES 2011367 to the patent ES 2003771, a series of improvements introduced in the source are shown ornamental described in the main patent. These improvements basically they consist of lighting projectors submersibles that each have four lamps of colors, slit, green, blue and white, fed with control of power and individually with each other.

As you can see all these systems are based on the use of traditional lamps, usually waterproof or submersible, although they achieve the desired goal, the range final obtained in the different shades of colors and mix is relatively quite low. Also when counting a small number of projecting lamps each of the bulbs, the effects that They can get are very small.

On the other hand, these lighting systems already registered based on the use of traditional lamps, they have an additional disadvantage due to the high number of breaks and cast lamps.

Therefore, the object of the present invention It is to overcome the above disadvantages, getting double purpose of obtaining means and a lighting system, whose maintenance needs are relatively null, and in that the color range that can be obtained in a controlled manner for each One of the foci is clearly increased.

Description of the invention

The multimedia lighting system object of the invention, as well as the focus necessary for such a system consists basically in the use of spotlights whose lighting means They are a multiplicity of LEDs, controlled either by groups or individually, and they present different colors, so the Color range and the effects achieved are very wide.

The system has a coordinated electronics that allow the control and governance of each of the Spotlights that make up the lighting system.

The focus, as an individual element, starts from lighting system, as we have already mentioned, with some projection means based on the use of a plurality of LEDs, of different colors.

The LEDs are fed either individually or by groups through exciter circuits or "drivers" specially designed for it. Each of these circuits drivers associated with each LED or group of LEDs receive a signal of pulse width modulated government from a unit of control.

That is, the multimedia lighting system, therefore it has a control unit that receives two control signals via RS485, a power supply, and depending on said control signals, generated for each focus or group of foci satiated, signals responsible for the excitation of a certain group of LEDs within each focus.

In addition to the control signals that go to each group of LEDs of each focus or group of spotlights, it is sent also a power connection as a power connection land.

Therefore, thanks to the control system of the lighting system, you can carry out the control of a plurality of foci, either individually or in groups, where the signals sent to each focus or group of spotlights, allow the lighting control of each LED or group of LEDs.

Thanks to the described system you can obtain a  much greater chromatic plurality, also a greater play of effects by the ignition control that can be performed on each LED, or group of LEDs within each focus, where also the Maintenance to be performed is minimal.

Preferred Embodiment of the Invention

In view of the aforementioned figures, describes below a preferred embodiment of the invention as well as the explanation of the drawings.

The focus (1) used for the system multimedia lighting of the invention, is shown in figure 1, where we can see that it is formed by a series of LEDs (2) specifically 18. The focus has a body that perimeter It has an annular recess (4) where the LEDs (2) are housed. In the central part of the focus body there is a recess of greater depth than the rest of the body where the card is housed Electronic (7) LED power supply.

All annular recess (4) is covered by a transparent cover (5) sealed inside by the use of two o-rings (6).

These constructive characteristics make the spotlight (1) used in the lighting system, be tight, preventing the penetration of water or any sunken particle where the lighting LEDs are housed. Thanks to the tightness obtained it is possible to use the present foci within sources.

The wiring entry into the body (3) of the focus (1), is carried out from the bottom through a threaded tube (9) through which the cable (10) runs, leaving set by a press (8).

In figure 2, the characteristics are observed constructive that presents the electronic card (7) in this way of realization, where the 18 LEDs, have been grouped into three groups of 6 LEDs each group, being LEDs, of each group of the same color, So there are red, green and blue LEDs.

Each group of LEDs receives power from a specially designed driver or driver circuit (11) to achieve a correct illumination of the LEDs, from a pulse width modulation signal from the unit control.

Thus the red LEDs (2.1) receive the power supply through the circuit (11) that in turn receives the signal (24.1). The green LEDs (2.2) receive the signal (24.2) and the Blue LEDs (2.3) receive the signal (24.3), also coming from the control unit (16) (figure 4).

In figure 3, we observe how the driver or driver circuit (11), which from the modulated signal in pulse width from the control unit, (16), generates the necessary power to the LEDs (2), having connected in its output a solid state switch (14), an inductor (13), and in that the current flowing through the LEDs is regulated by a resistance (12).

In the case of having several foci that they have LEDs, as lighting projection means are design a control system, like the one shown in the figure 4, where inside a box (15) a unit of control (16), the box has two inputs through the which enter inside the box (15), signals of control (17) and (18), while penetrating through another input inside the box the power cable (19). The rest of the entrances are to allow the passage of the cables that go from the control unit (16) to each of the bulbs (1) to control.

In figure 5, the wiring that goes from the control unit (16) to each of the bulbs, observing that the bulbs (1) have been grouped into three groups, each of three bulbs, so the lighting signal of each color to each group of spotlights, it is divided into three to reach Each focus individually.

Finally in figure 6 we observe the control unit electronics (16), into which the control cables (17) and (18), the power cable (19) and the power cables (26) come out to each of the bulbs, the reference or ground wires (25) to each of the bulbs, as well as the cable groups (24) that carry the government signal of each of the colors to each of the spotlights.

The control unit internally has a  power supply (20), a coupling device (21) of the control signals (17) and (18), a microprocessor (22), and means (23) of pulse width modulation, from the signals generated in the microprocessor (22).

Thanks to this system and the lights used not only is it possible to govern each focus or group of foci, but that also the individual projection means, this is the LEDs, which make up each vilo of the spotlights. This way the range Chromatic of possible combinations obtained is very wide. further on the other hand, given the nature and low failure rate of the LEDs, maintenance is virtually nil.

It does not alter the essentiality of this invention variations in materials, shape, size and arrangement of component elements, described in a non-limiting manner, sufficient This one for reproduction by an expert.
