| 摘要 |
The invention concerns a LED lighting body (1) comprising an inner tubular structure (2) made of a heat conducting and electrically insulating material, LEDs (6) associated with a first end (3) of the inner tubular structure (2), an electronic control circuit (8) of the LEDs (6) housed in the inner tubular structure (2), a base (9) associated with a second end (4) of the inner tubular structure (2) on the side opposite the first end (3) and electrically connected to the control circuit (8) and a sleeve (11) arranged externally and coaxial with the inner tubular structure (2), which defines at the level of the first end (3) of the inner structure (2) an annular housing (12) which accommodates a lower portion (131) of a bulb (13) covering the LEDs (6). The sleeve (11) of the lighting body is made of a heat conducting material and its inner surface (111) is in contact with the outer surface (21) of the inner tubular structure (2) to obtain the dissipation by convection towards the outside of the heat it receives following its contact with the inner tubular structure (2). |
