1. A light emitting diode (LED) device comprising:

  • an aluminum base comprising two first channels arranged in parallel, and a heat dissipation channel between the two first channels where each first channel has a top slot opening partially covered by at least a top wall, the aluminum base is configured with a first locking element adjacent to each top slot opening, the first top slot openings, the top wall, and the two first locking elements are all along the length of the aluminum base, and all face upward;

    a LED lighting module joined to a top side of the aluminum base where the LED lighting module comprises a circuit board, the circuit board has one or more LED lighting elements and the LED lighting elements are connected to at least a connector assembly configured at an end of the circuit board, the connector assembly comprises a first terminal, a second terminal, and a bridge element, the first terminal has a first end electrically connected to a positive terminal of the circuit board, the second terminal has a first end electrically connected to a negative terminal of the circuit board, the bridge element has a second locking element configured at each end, and each second locking element is locked to a corresponding first locking element;

    a heat dissipation plate positioned between the aluminum base and the LED lighting module where a first major side of the heat dissipation plate is configured with a first heat conduction surface and a second major side of the dissipation plate is configured with a second heat conduction surface, the first heat conduction surface is attached a bottom side of the LED lighting module, and the second heat conduction surface is attached to the top wall of the aluminum base;

    two insulating strips, each threaded in a first channel where each insulating strip has a second channel with a second top slot opening corresponding to the first top slot opening of the first channel, and, in a first lateral side wall of each second channel, a third channel connecting and tangent to the second channel is provided; and

    a first conductive strip and a second conductive strip where each of the first and second conductive strips is threaded in the third channel of an insulating strip, and each of the first and second conductive strips is exposed in the second channel;

    wherein, as the LED lighting module is joined to the aluminum base, the second locking elements are locked to the corresponding first locking elements, the first terminal contacts the first conductive strip, the second terminal contacts the second conductive strip, and the second heat conduction surface contacts the top wall of the aluminum base.
