| 摘要 |
The present invention utilizes the outer and/or inner surface of the cup-shaped heat dissipater (100) having heat conductive rib therein served for accommodating the electric luminous body (200), and with the heat conductive rib structure (310) connecting with the inner periphery and the bottom of the cup-shaped inner recessed structure of the heat dissipater (100), and the heat source zone installed with the electric luminous body (200), the heat of the electric luminous body (200) can be assisted to be transmitted via the heat conductive rib structure (310) to the surface of heat dissipater (100), so as to be dissipated to the surrounding. |
