1. An LED lamp (10) comprising:

  • a) a heat sink (12), said heat sink (12) defining a first region (24) adapted to receive in operative electrical and mechanical association an electronics module (16) and a second region (26) adapted to receive in operative electrical and mechanical association a light module (14), said heat sink (12) further defining a passageway (32) extending between said first region (24) and said second region (26);

    b) an electrical interconnector (18) disposed in said passageway (32) and having at least first and second electrical contacts (66) extending between said first region (24) and said second region (26), said first and second contacts (66) being exposed within each of said first and second regions (24, 26) and adapted for making selectively attachable and detachable electrical connection in both said first and second regions (24, 26);

    c) an electronics module (16) adapted to be, as a unit, received in and selectively replaceably detached from said first region (24), said electrical module (16) comprisingi) a socket (68) adapted to make electrical connection to an external power source;

    ii) control circuitry (62) adapted to receive power from the power source and provide power to light emitting diodes (LEDs) (34);

    iii) a coupling structure (70, 72) adapted to selectively attachably and detachably retain said electronics module (16) to said heat sink (12); and

    iv) a first electrical connector (64) adapted to selectively attachably and detachably form an electrical connection to portions of said first and second contacts (66) in said first region (24); and

    d) a light module (14) adapted to be, as a unit, received in and selectively replaceably detached from said second region (26), said light module (14)comprising;

    i) at least one light emitting diode (LED) (34);

    (ii) an optical element (36) in register with the LED (34) adapted to shape light emitted therefrom; and

    iii) a second electrical connector (38) in operative association with said at least one LED (34) and adapted to selectively attachably and detachably form an electrical connection to portions of said first and second contacts (66) in said second region (26), wherein the electronics module (16) when retained in the first region (24) supplies power to the light module (14) when retained in the second region (26).
