CONSTITUTION: A tube type led lighting device includes a power module(20), a light emitting modules(22a,22b), a heat sink module(24), a light transmitting tube(14), and an external cap(12). The power module receives power from an electrical terminal and converts it into the power for the LED, and the light emitting module is electrically connected to the power module. The light emitting module includes a plurality of LEDs(L). The heat sink module is contacted with the light emitting module closely and absorbs heat emitted from the light emitting module, and then emits it. |
