A laminated heat-dissipating and non-disposable LED lamp (100) includes a lamp holder (10), an LED luminous module (20), a lampshade (30) and a heat dissipation unit (40). The lamp holder (10) is provided with a hollow shell (11), the LED luminous module (20) is assembled on the lamp holder (10) and the lampshade (30) is mounted on the LED luminous module (20). The heat dissipation unit (40) is covered around the circumferential side of the lamp holder (10), instituted of a multi-ply heat-dissipating layer (41). By so designing, heat energy produced by the LED lamp (100) can be transmitted to the heat dissipation unit (40), and the heat-dissipating layer (41) can function to increase a heat dissipation area and a heat dissipation distance of contact of the LED lamp (100) with open air, able to prolong service life and enhance luminous efficiency of the LED lamp and also reduce electronic waste. |
