| 摘要 |
The invention relates to a LED lamp (1) shaped as a slim conventional luminous tube, the LED lamp (1) comprising an elongated tubular glass casing (9), a socket (11, 11′) arranged at both ends, a LED unit (3) comprising a plurality of LED circuits (5) arranged on an elongated circuit board (7), and at least one conductor (18, 27, 31), the LED unit (3) being fixated against the first side of a support structure (35), the support structure (35) serving, in the operation of the LED lamp (1), to conduct heat away from the LED circuits (5). The support structure comprises a second side, abutment surface (40) opposite the first side, of the support structure (35), which abuts against the inside (10) of the glass casing (9), the support (35) extending in the longitudinal direction of the LED lamp (1) such that a distance (a) is attained between the support structure (35) and the socket (11, 11′). The invention also relates to a method of preparing the LED lamp by providing the LED unit (3) including the support structure (35) and providing the glass casing (9) at various work stations, and the LED unit (3) is inserted to a predetermined position in the glass casing (9), in which position the support structure (35) extends in the longitudinal direction of the LED lamp (1) such that a distance (a) is attained between the support structure (35) and the socket (11, 11′). |
