Definitions

  • the present invention relates to an LED lamp and to an associated network of lamps connected in series to each other.
  • lamps or spotlights of the RGBW type i.e., with red, green, blue and white LEDs, controlled via DMX512 protocol
  • This protocol allows to send a numerical value from 0 to 255 to 512 channels with a single three-conductor cable.
  • the light control unit that controls a plurality of spotlights starts sending to the DMX chain the value of the first channel, then the value of the second channel, and so on up to the last channel that can be controlled by the unit, and then resumes from the first one.
  • Lamps or spotlights of the known type controlled by means of the DMX512 protocol, require the use of five conductors, two for power supply (positive power conductor and negative power conductor) and three signal conductors, and four channels to manage the four colors of each lamp or spotlight.
  • the aim of the present invention is to provide an LED lamp and an associated lamp network in which it is possible to manage the lamps or spotlights with fewer wires than the traditional five used with the DMX512 protocol.
  • an object of the present invention is to provide an LED lamp and an associated network of lamps in which the management of the four colors, red, green, blue and white of the lamp, is possible with a reduced number of DMX512 channels with respect to the standard.
  • a further object of the present invention is to provide an LED lamp and a lamp network which is suitable for driving over.
  • Another object of the present invention is to provide an LED lamp and an associated lamp network which can be of different types for different kinds of use.
  • Not least object of the present invention is to provide an LED lamp and an associated network of lamps that is highly reliable, relatively easy to provide and at competitive costs.
  • an LED lamp characterized in that it comprises a lamp body with a power supply and command cable which has an input connector and an output connector, the power supply and command cable being provided by means of four wires for power supply and color control of the lamp via DMX512 protocol.
  • the LED lamp according to the present invention is generally designated by the reference numeral 1 in a first embodiment.
  • the LED lamp 1 comprises a lamp body with a printed circuit board 2 with LEDs and control electronics.
  • the printed circuit board 2 is conveniently embedded in a transparent resin casting 3.
  • the printed circuit board is provided with four RGBW LEDs 4, i.e., a red LED, a green LED, a blue LED, and a white LED, or a single white LED.
  • the lamp 1 is powered by a power supply and command cable 5 with an input connector 6 and has, at the opposite end, an output connector 7 that allows series connection to an additional connector 6 of a subsequent lamp 1.
  • a heat sink 8 is provided under the circuit board 2.
  • the power supply and command cable 5 provides for the use of four conductors instead of the traditional five required to handle the DMX512 protocol and the power supply, while maintaining the standard DMX512 protocol.
  • the four conductors are obtained by using a solution with common ground between the power supply and the signal, removing the shielding braid conductor.
  • the lamp according to the invention has an IP68 weather resistant rating and IK8/9 vandal resistant rating and is therefore suitable for driving over and can also be placed in the ground.
  • the four lamp colors i.e., the four LEDs
  • Figure 3 is a view of a second embodiment of the lamp, designated by the reference numeral 10, in which the transparent resin casting is provided in the form of a porphyry cube 11 and has an internal cavity 12 that can be filled with resin.
  • a collimating lens 13 can be provided at the printed circuit board 2 and is accommodated within the cube 11.
  • the collimating lens or collimator 13 allows to obtain a directed beam of light that exits from the cube 11.
  • the lamps according to the invention by means of a hole provided in the heat sink that is arranged behind the printed circuit board, it is possible to hang the lamps according to the invention, for example, on the face of a building, so as to form a matrix of pixels with a minimum spacing of, for example, 100 mm, thus creating a giant screen.
  • the lamps according to the invention can be connected to each other in series so as to provide a network of lamps in which the first lamp of the network or line receives the address and provides the subsequent addresses to the other lamps connected in a sequential configuration.
  • the lamp according to the present invention fully achieves the intended aim and objects, since it can be controlled in color management by using only three DMX512 channels and moreover allows to manage and power it with only four conductors.
  • the materials used, as well as the contingent shapes and dimensions may be any according to the requirements and the state of the art.
