Abstract
A built-in starter type fluorescent lamp socket in which the starter is entirely incorporated with the socket with no protruding parts and in which it is not necessary to replace the starter. The socket includes a socket body, pairs of starter contacts and power source contacts operatively positioned in the socket body for making connection with fluorescent lamp pins, and an electronic starter positioned in the socket body and connected to the starter contacts. The electronic starter includes a non-linear dielectric element and a thyristor coupled in parallel and across the starter contacts. The anode of the thyristor is coupled through a Zener diode to the common connection point between voltage division resistors also coupled across the starter contacts. The socket body may include a casing having lamp pin inserting holes and a cover for covering the rear side of the casing wherein the cover may be shaped in the form of a box in which the electronic starter is mounted. In a preferred embodiment, the casing is provided with a lead wire receiving portion which together with the cover clamp the lead wires which are connected to the power source contacts.
