In the present embodiment, the LED fluorescent lamp 106 uses a relatively high-powered light-emitting diode 416, and the light-emitting two-body heat-emitting rate is high, and the LED fluorescent lamp 1〇6 has a high requirement for the heat-dissipating structure. The heat dissipation base 160 ..s is manufactured by integral molding. The bottom of the heat dissipation base 160 is provided with a heat dissipation fin 116. The heat dissipation base 160 is further formed with a concave portion 126, and the concave portion 126 is opposite to the heat dissipation fin 116. The light source substrate 406 is disposed in the recess 126 on the heat dissipation base 160. The heat sink base 16 further includes a reflective concentrating cover 206 disposed above the light source substrate 406, and the reflective concentrating cover 206 is parabolic or near parabolic in cross section. The reflective concentrating cover 206 is coated with a reflective layer to form a reflective concentrating surface, and the back surface of the reflective concentrating cover 206 is also provided with a heat dissipating film 116. The opening position of the reflective concentrating cover 206 is further provided with a condensing lens 256'. The condensing lens 256 can be fixed to the reflective concentrating cover 206 by means of snapping and gluing. 099129169 Form 蹁 Α 0101 Page 9 / Total 22 pages 0992051183-0 201209323 [0023] Those skilled in the art will recognize that the above embodiments are merely illustrative of the invention and are not intended to limit the invention.
