A light emitting diode lamp bulb structure (Z) comprises a heat dissipating base (1), a power source connector (2), a light emitting module (3), a insulation cover body (5) and a light transmitting shade (6). The power source connector (2) is arranged at the bottom end of the heat dissipating base (1). The light emitting module (3) comprises an electric circuit substrate (30) arranged at the top end of the heat dissipating base (1) and a plurality of light emitting diode chips (31) encircling arranged on the upper surface of the electric circuit substrate (30) and positioned in the vicinity of the outer periphery surface of the electric circuit substrate (30). The insulation cover body (5) is arranged on the electric circuit substrate (30). The insulation cover body (5) is provided with an encircling main body part (51), a protruding part (52) arranged at the top end of the encircling main body part (51), and an encircling extension part (53) encircling extended outwardly from the bottom end of the main body part (51) and arranged on the electric circuit substrate (30). The light transmitting shade (6) is arranged on the encircling extension part (53) and covers the encircling main body part (51). A pass-through opening (600) for exposing the protruding part (52) is arranged at the top end of the light transmitting shade (6). The thickness of the light transmitting shade (6) is decreased gradually from bottom to top. The heat dissipating path can be shortened by means of the light emitting diode lamp structure (Z). |
