ABSTRACT:
A wedge-type lamp bulb assembly consists of a bulb containing a filament and a wedge-shaped base extending from the bulb. Several lead wires connected to the filament are led out from the bottom of the wedge-shaped base, and folded along the front and rear sides of the wedge-shaped base. There are provided inside the socket in which the wedge-shaped base is removably held a plurality of terminals which are in resilient contact with the lead wires, and a pair of guide protrusions is formed on the inner walls of the socket along the inserting direction of the wedge-type lamp bulb. There is formed on the front and rear sides of the wedge-shaped base in positions corresponding to the pair of guide protrusions a pair of protrusions defining guide ways through which the guide protrusions are passed. Thus, the wedge-type bulb can be easily assembled into the socket and also securely held therein.
