A cylindrical body having a shape that is inserted into the second case 310 and the rear end thereof is hooked and supported, and has an inner hollow to support a lower portion of the second terminal member 330, A rotation support member 340 having an engagement protrusion 341 for inserting an end engagement protrusion 341a into a coupling hole 322 of the coupling member 320 to prevent the rotation member 320 from being detached from the outer side;
A socket base 350 coupled to a rear end of the second case 310 and electrically connected to a connection terminal pin 331 of the second terminal member 330; The LED lamp of claim 1,
The method of claim 3,
A first rotation restricting protrusion 342 is protruded on one side of the outer surface of the rear end of the rotation support member 340 and a second rotation restricting protrusion 312 is protrudingly formed on one side of the inner wall of the rear side of the second case 310 However,
The first rotation restricting projection 342 and the second rotation restricting projection 312 are engaged with each other at one point to prevent the rotation member 320 from rotating endlessly, It is possible to prevent the second terminal member 330 from being twisted and to be electrically connected to the socket base 350 when the coupled lamp body coupling unit 200 is assembled to the socket unit 300 coupled to the lamp unit 1 Wherein the recessed portion of the recessed portion is configured to prevent breakage of the recessed portion.
3. The method of claim 2,
An air vent hole 223 is formed in the first terminal member 220 so as to communicate with the lower side surface of the first terminal member 220 so as not to interfere with the terminal pin 221,
A sticker attachment groove 224 is formed on the upper surface of the air vent hole 223 and the Gore-Tex sticker 500 is attached to the sticker attachment groove 224 to allow air to pass therethrough, So that the air vent function can be exerted. [2] The retro-pit type LED lamp according to claim 1,
