<p>PURPOSE:To enable a multiluminous source fixture to be set up in a simple unit and kept free of danger even when it is applied to any common device other than those designed for peculiar purposes, in such a way as composing the receptacle base of a certain implement with three-way base and connecting the fluorescent lamp side terminal of a incandescent lamp to one of the electrodes opposite to the common electrode. CONSTITUTION:The fluorescent lamp 1 side of incandescent lamp 3, namely the terminal on electrode 1b side is directly connected to the 3rd electrode 2c of three- way base 2. The pre-heating circuit closing the both terminals of fluorescent lamp 1, i.e. 1a and 1b, is formed in series connection including the gow starter 4, and especially in parallel with the starter 4 is provided a circuit consisting of a condenser 5 and the primary coil of a compact pulse transformer 6, with its secondary coil output trminals respectively connected to one terminal 1a of fluorescent lamp 1 and the auxiliary electrode 7 installed near the external wall of the lamp 1. Thus, applied without danger to any device other than those specially designed for this luminous source.</p> |
