A LED light bulb with multiple layers of radiating structures, comprises a LED circuit carrier, a main body 02) of a lamp cup, a controller (04), LED chips (05) and a lamp cover (06). The LED circuit carrier can be a planar LED circuit carrier (10), which has an A base load surface (101) and the whole circle of the edge of which s folded into a wide edge (014). The LED circuit carrier can be also a cap-like LED circuit carrier (01), the center part of which is humped to form the first base load surface (011). The whole circle of the edge of the first base load surface (011) is folded into a wide edge (014), then folded again towards the circumambience and extends to form a brim-like second base load surface (012) and continues to form the Nth base load surface by analogy. The main body (02) of the lamp cup has a structure of multiple layers, and comprises the first layer amp cup (021), the second layer lamp cup (022), and till the Nth layer lamp cup by analogy. Each base load surface (101, 011, 012) is provided with a circuit board. The LED circuit carrier is made of heat conductive material. The main body (02) of the lamp cup is made of radiating material. Radiating vents (03) are densely distributed in the side walls of the second layer lamp cup (022) till the Nth layer lamp cup. The LED light bulb with multiple layers of radiating structures has a good radiating effect and a long life. |
