Fluorescent lamp with replaceable light element
First Claim
1. A lighting system comprising:
- first and second gas discharge vessels, each of said discharge vessels having at least one electrical contact pin extending vertically from each end thereof;
a holder for said gas discharge vessels, said holder containing a first socket for removably mounting said first gas discharge vessel, and a second socket for removably mounting said second gas discharge vessel;
a plurality of recessed electrical contacts in each of said sockets, said recessed contacts adapted to mate with the electrical contact pins of said gas discharge vessels;
first and second current limiting devices in said holder, an output side of said first current limiting device electrically connected to a recessed electrical contact in said first socket, and an output side of said second current limiting device electrically connected to a recessed electrical contact in said second socket;
a common power supply, said power supply having an input portion which is connected to a source of mains power, and an output portion having a plurality of electrical outlets;
a first supply line connecting a first outlet of said power supply to said first current limiting device, and a second supply line connecting a second outlet of said power supply to said second current limiting device; and
a common electrical outlet line connecting said power supply output portion with a recessed electrical contact in said first socket and a recessed electrical contact in said second socket.

Abstract
The invention concerns a construction kit system for fluorescent lamps (1) with separate choke unit. Standard low-power modules which are cheap and easy to manufacture can in particular be plugged in any combinations into choke units fitted as compact lights or in lamp housings. A number of examples are given to show the new possibilities for constructing lighting systems. These fluorescent lamps each have a replaceable light element comprising at least one gas discharge vessel (1) with a base at one end as the light element and at least one choke unit (6) in the form of a separate unit fitted in a housing and capable of electrical connection via plug connectors (2) to the light element. The light element is designed as a standard low-power module with a glass tube diameter of the gas discharge vessel of no more than 13 mm, thus allowing it to be plugged into different housings individually or in groups.
