A lamp (1) has one or more LED's (2), supported above an open structure (7). The lamp (1) is made from thermoplastic material and has a base (3) including threads (4) and a lower contact (5). A thermoplastic body (6) of larger diameter is located above the base and has an open structure portion (7) preferably shaped as a truncated inverted and open cone. An upper part of the cone supports a circuit board (8) with a laminar form that supports the light emitting diodes (2). A upper semispherical element (9) is located over the body (6) and forms a light diffuser. An upper center of the base (3) has an internal electronic circuit (10) for connecting to a power source. The LED lamp with the open structure eases installation, has lower weight and cost, allows easy recycling and provides greater security for users.
