A lamp panel plugged type light-emitting diode (LED) lamp bulb, comprising a lamp holder (1) and a lamp bulb shell (2) fixedly connected to the lamp holder (1), and further comprising an insulation fixed seat (3) and a lamp panel type light source assembly (4) for vertical mounting;

• the insulation fixed seat (3) is arranged at an opening portion of the lamp bulb shell (2);
• the insulation fixed seat (3) at least comprises an assembling portion (31) and a plugging portion (32) configured to mount the lamp panel type light source assembly (4);
• the plugging portion (32) is provided with a plugging slot (321);
• at least two conductive contacts a (322) are provided on an inner side of the plugging slot (321);
• one conductive contact a (322) is electrically connected to a positive electrode of the lamp holder (1);
• the other conductive contact a (322) is electrically connected to a negative electrode of the lamp holder (1);
• the lamp panel type light source assembly (4) at least comprises a base plate (41) and light-emitting diodes (LEDs) (42) which are arranged along at least two opposite surfaces of the base plate (41) and are electrically connected;
• the base plate (41) is provided with two conductive contacts b (411);
• one end of the base plate (41) is plugged into the plugging slot (321) to make the conductive contacts b (411) communicate with the conductive contacts a (322);
• and the other end of the base plate (41) extends into the lamp bulb shell (2).
