ABSTRACT:
A socket bulb includes a shell inside which a depression device, a clamp device, and conductive plates are arranged. The shell has a lower opening through which the base of a bulb can be put into the shell in a linear movement. Depression operation of the depression device by the base of the bulb moves the clamp device to move between a raised position and a lowered position. When the clamp device is moved from the raised position to the lowered position, the bulb is securely retained inside the shell in electrical engagement with the conductive plates through which power is supplied to the bulb. When the clamp device is moved from the lowered position to the raised position, the bulb is released and can be withdrawn easily. As such, an efficient and safe structure for mounting and dismounting a bulb in a socket is provided.
