Abstract
An electric lamp () has two pairs of external connection pins () adapted for connecting the lamp to a voltage source for powering an internal lighting module (). Each pair of pins is disconnected from the lighting module by an open switch () unless a non-zero electric voltage is applied to the pair and causes the switch to close. The lamp is therefore safe to handle even in a condition where one pair of pins is connected and the other is not. The lamp may be fitted in a switch-start fixture, providing an ohmic connection between two pins in different pairs, as well as a rapid-start fixture, with a capacitive connection.
