the same.

The control module is based on the use of pulse width modulation control signals (PWM) or by means of a control voltage.

In addition, this type of device achieves the illumination of spaces with low consumption, low heat emission, low maintenance and high luminosity.

The disadvantage of this type of device is that once it is designed it cannot be expanded or modified to adapt it to new lighting needs, without the use of additional wiring that allows adding new elements, which determines that by changing the needs lighting, it is necessary to design a new device adapted to the new conditions required.

In addition, this type of device does not allow the effects to be modified to be modified by lighting, which also represents the realization of a new design when it is required to vary the lighting effect.

DESCRIPTION OF THE INVENTION

In order to achieve the objectives and solve the aforementioned drawbacks, the invention has developed a new LED lighting device, which, like those provided in the prior art, requires a direct current power supply that is connected to a switched source. constant current, whose switching is governed by a control module, to feed a plurality of LEDs and thus regulate their brightness.

The main novelty of the invention is that the device comprises at least one circuit board

printed that is provided with an input connector connecting with the DC power supply and with a plurality of control modules of said constant current switched source. Both the DC power supply and the control modules are located outside the printed circuit board.

In addition, the printed circuit board is provided with the constant current switched source, a plurality of LED diodes, connected to the switched source, and a

module

keep going to the that be connect the source from

DC power supply, through the input connector and to which the constant current switched source is also connected to provide power to it.

It is also provided that the printed circuit board is provided with a plurality of control lines, each of which is connected to one of the control modules, through the input connector, and to which the selector module is also connected to allow selecting one of said control modules, and therefore it is allowed to establish one of the controls provided outside the printed circuit board, by which the brightness of the plurality of diodes included in the printed circuit board must be regulated.

Finally, the printed circuit board is provided with an output connector that both the direct current supply line and the control lines reach, allowing the connection of a plurality of printed circuit boards that interconnect a then another by joining the output connector of one board with the input connector to the next board and so on.

This configuration has the great advantage that it is possible to expand or reduce the number of interconnected printed circuit boards depending on the requirements required in lighting. In addition, this configuration allows a different control module to be selected by the selector module for each board that governs the switching of the constant current switched source, which allows to cause a different lighting effect with each of the printed circuit boards, being able to achieve different effects such as sunrise, dusk, storms, etc.

For example, this type of lighting is widely used in aquariums where the lighting screen varies depending on the dimensions of the aquarium, which allows by means of the invention to interconnect the different printed circuit boards with each other according to the required screen dimensions for each aquarium, at the same time that it allows different optical lighting effects to be governed by switching the different switched sources with different control modules, according to the control module selected by means of the selector module.

The invention provides that the control module can be a PWM module, a control voltage module, a processor module or a combination of the above to achieve the desired lighting effect as described above.

With respect to the selector module, in an exemplary embodiment it is constituted by a manually operated microswitch, so that the user, acting on the microswitches, selects the control module to govern the switching of the constant current switched source, but it is also possible that said selector module can be constituted by a switch that is governed by the processor module itself that constitutes the control module, to achieve the luminic effect depending on the

Programming done on the processor module.

The printed circuit board may consist of two plates, a first source printed circuit board, and a second illuminated printed circuit board.

The first source printed circuit board includes the input connector, the constant current switched source, the selector module and a first connector

to the second license plate from circuit printed from

lighting, it includes the plurality of LEDs, the output connector, and a second intermediate connector connecting with the first intermediate connector of the first source printed circuit board, to achieve the functionality that was already described above, but in This case achieves greater use because in the event of a malfunction of one of the diodes, it is enough to replace the second plate of the lighting printed circuit, or on the contrary in the case in which there is a malfunction of the first source printed circuit board, just replace this one.

Therefore, by means of the invention a versatile modular lighting device is provided that allows obtaining different lighting motifs and adapting to the different lighting needs that may be required, and all this without the incorporation of additional wiring with a significant cost reduction.

In order to facilitate a better understanding of this descriptive report and forming an integral part thereof, a series of figures are attached in which the object of the invention has been shown as an illustrative and non-limiting nature.
