Abstract
A lamp with an outer bulb in which a base (30) includes a base main body (32) having a contact terminal (31) electrically connected with a receptacle and an attaching member (33) fitted to the base main body (32) in a state of retaining the lamp main body (10) and an outer bulb (20), the attaching member (33) has an insertion hole (34) formed therethrough for inserting and retaining a pinch seal (14), and a flange (36) for abutment with the opening end (21) of the outer bulb formed at the outer peripheral surface (35) thereof, and a joint portion (40) is formed for engaging the outer peripheral surface of the attaching member (33) and the inner peripheral surface (23) of the outer bulb (21). An adhesive injection port (38) is opened to the bottom of the attaching member for filling the adhesive to the joint portion (40) in a state of mounting the outer bulb, thereby improving the commercial value by making the adhesive deposited to the insertion hole portion invisible externally, as well as preventing the outer bulb from detachment and mitigating inventory control depending on the type of the bases.
