A pin type LED lamp, comprising a lampshade (1), a light source assembly (2) and pins (3); the lampshade (1) comprises a first light guide portion (11), a second light guide portion (12) and a third light guide portion (13), the first light guide portion (11) has an ultra-thin flat structure, and both sides of the connection between the first light guide portion (11) and the second light guide portion (12) are provided with a connecting inclined surface (14); the light source assembly (2) is provided with a heat dissipation module (22) and a light source module (21), the heat dissipation module (22) has a cylindrical structure and is arranged inside the second light guide portion (12); and the light source assembly (2) is axially and uniformly distributed on the outer side wall of the heat dissipation module (22) by taking the axis of the lampshade (1) as a center. In the pin type LED lamp, the solid lampshade (1) having a three-section structural design is adopted, so that light is concentrated on the second light guide portion (12); light sources in the light source assembly (2) are flatly arranged on a flexible substrate by using a flip chip LED structure, so that the light source module (21) is changed into a rolled hollow cylindrical structure from a straight plate state; and by taking the axis of the lampshade (1) as a center, light of the light source module (21) adopting such a structure can be uniformly guided around a 360-degree circumference without dead spaces, so that light guided by the lamp is bright and uniform.
