摘要

The LED lamp (1) has several LEDs (5), base (10) and heat sink (4). The LEDs are thermally connected to lamp portion (2) to generate luminous flux of 800 In. The heat sink is connected lamp portion. The predetermined area enclosed by convex hull of lamp portion is filled with material such as aluminum or aluminum alloy. The length of lamp is between 10 cm and 14 cm, and maximum diameter of lamp is between 5 cm and 7 cm and the mass of lamp portion is between 200 g and 250 g.
