Lamp with screw socket and its manufacturing method

摘要

A bulb-form lamp allows a lighting circuit and an eyelet to be easily and reliably connected together without using any soldering or plasma arc welding or lead wires, prevents a lighting failure caused by an inappropriate contact, and reduces costs while improving productive efficiency. The bulb-form lamp comprising a case (12) having a lighting circuit (10) accommodated inside and a base (13) formed at an end portion of the case and having an eyelet (11) and a screw-like shell (9). The lighting circuit (10) and the eyelet (11) are connected together without any lead wire.
