The present disclosure has the following advantages: 1. The structure of a luminous element is improved, which effectively solves the technical problem of light shadow generated by the lamp bulb during use; 2. The lamp bulb has a novel structure and higher decorability; and 3. The overall lamp bulb is convenient to assemble and higher in production and assembling efficiency. ## Claims ### Claim 1 A shadowless waterproof LED lamp bulb, comprising a lamp holder (1) and a lampshade (2) connected to the lamp holder (1), further comprising a lampwick component (3) and a sealing plug (4); the lampwick component (3) comprises a base plate (31), a first metal support line (32), and a second metal support line (33); the base plate (31) extends to be provided with a light source part (311); the light source part (311) extends into the lampshade (2); the light source part (311) is provided with an LED light-emitting chipset (312) on at least one side; the light source part (311) is provided with conductive wires (313) at two ends of the LED light-emitting chipset (312); the conductive wires (313) extend to the base plate (31) and is electrically connected to the metal support lines; the other end of the first metal support line (32) and the other end of the second metal support line (33) are both electrically connected to the lamp holder (1); a rubber base (34) is further arranged in middle parts of the first metal support line (32) and the second metal support line (33); the sealing plug (4) is assembled at an opening part of the lampshade (2); and the sealing plug (4) is provided with an assembling hole position (41) configured to assemble the rubber base (34). ### Claim 2 (depends on 1) The shadowless waterproof LED lamp bulb according to claim 1, wherein the sealing plug (4) and the opening part of the lampshade (2) form a filling recess (5), and the filling recess (5) is provided with a sealant layer (51). ### Claim 3 (depends on 1) The shadowless waterproof LED lamp bulb according to claim 1, wherein the assembling hole position (41) comprises an upper hole position (411) and a lower hole position (412) which are arranged in sequence from top to bottom; the upper hole position (411) is communicated to the lower hole position (412); and a diameter of the upper hole position (411) is less than a diameter of the lower hole position (412); the rubber base (34) comprises an upper cylindrical part (341) and a lower cylindrical part (342) which are integrally arranged; the upper cylindrical part (341) is matched with the upper hole position (411); and the lower cylindrical part (342) is matched with the lower hole position (412). ### Claim 4 (depends on 1) The shadowless waterproof LED lamp bulb according to claim 1, wherein widths of upper ends of both the first metal support line (32) and the second metal support line (33) are greater than widths of lower ends. ### Claim 5 (depends on 1) The shadowless waterproof LED lamp bulb according to claim 1, wherein the rubber base (34) is integrated on the metal support lines in an injection-molding manner. ### Claim 6 (depends on 1) The shadowless waterproof LED lamp bulb according to claim 1, wherein the lampwick component (3) further comprises a resistor (6); and the resistor (6) is arranged on the first metal support line (32) or the second metal support line (33). ### Claim 7 (depends on 6) The shadowless waterproof LED lamp bulb according to claim 6, wherein the rubber base (34) is arranged outside the resistor (6). ### Claim 8 (depends on 1) The shadowless waterproof LED lamp bulb according to claim 1, wherein the lampwick component (3) further comprises a resistor (6); and the resistor (6) is arranged at the light source part (311). ### Claim 9 (depends on 1) The shadowless waterproof LED lamp bulb according to claim 1, wherein a surface of the light source part (311) is further provided with a fluorescent adhesive layer (314) configured to package the LED light-emitting chipset (312) and the conductive wires (313). ### Claim 10 (depends on 1) The shadowless waterproof LED lamp bulb according to claim 1, wherein a diameter of an upper end of the sealing plug (4) is less than a diameter of a lower end.
