Another option shown in Figure 10 is that a power cable (6) is connected to the plate (3) that is arranged at an angle to the LED strip (1), specifically the angle is right in the representation of the figure , as represented on a face of the base (2.1), when this is a quadrangular prism, different from the face in which the housings are located (2.4,2.7), although it is not limited and could also be on that same face always and when there was enough space for the cable (6).

Another option shown in Figure 11 is that two connectors (2) are connected to each other by means of a connection cable (7).

Another option shown in all the previous configurations is that at least one of the tabs (2.2,2.3,2.5,2.6,2.8,2.9,2.11,2.12) has two protuberances (2.14) arranged parallel and oriented towards their corresponding housings (2.4, 2.7,2.10,2.13), so that between which the envelope (1.3) of the LED strip (1) can run, which can also have steps, not shown, that correspond to said protuberances (2.14). In this way the envelope (1.3) is clamped in the connector (2) in a guided and firm manner.

Another option that can be implemented in all the configurations mentioned as being advantageous, is that the connection means (4) are screws, although they could be of another type provided they fulfilled the same function, such as needles, plates or the like, for example. Specifically, each screw (4) comprises a head (4.1) followed by an intermediate section (4.2) of smaller diameter than the head (4.1), is followed by a rod (4.3) of smaller diameter than the intermediate section (4.2), optionally the device also comprises a washer (5), represented in figures 1 and 8, of plastic or rubber material, which is arranged surrounding the intermediate section (4.2) of the screw (4) so that it is what makes Electric contact with the plate (3) and the washer (5) guarantees the tightness against liquids already solids.

According to the connectors (2) that have been exposed, an illumination device can be formed so that it covers any surface and describing any path since the connectors (2) allow it, even if in any way the power supply arrives and at any point of the device.

For example, the device could start with a connector (2) with power cable (6) like the one shown in figure 7, continue with a LED strip (1) to a quadruple connector (2) like the one in figure 6 , from one of its branches continues with a LED strip (1) to a double connector (2) like the one in figure 2, continues with a LED strip (1) to a triple connector (2) like the one in figure 5, one of its branches continues with a strip of LEDs (1) to a salvageable closed curve with a double connector (2) like that of Figure 11, continues with a LED strip (1) to a double connector (2) with power cable (6) like the one in figure 10, etc. All this allows the construction of multiple and varied structures in several dimensions easily and quickly.

The figures show, for each connection two holes (2.21,2.51,2.81,2,111) and the concentric ones to them in the plate (3), with its connection means (4) because the cable, power (6) or connection (7), includes two wires, one for the positive pole and one for the negative. However, as stated, the invention may contain cables with any number of wires from two: three, four, five, etc. For example, the four-wire one is commonly used in which one carries the power supply, normally 12 Volts, and the other three are one for each color: R ("Red" for red), G ("Green" for green ) and B ("Blue" for blue).
