Abstract
A retrofit assembly and kit provide for the retrofitting of a low-frequency T12 fluorescent light fixture with a magnetic ballast with high-efficiency high-frequency T5 fluorescent bulbs. Since the lumen output of the T5 retrofit lamp is greater than that of the equivalent T12 bulb, and typically more than desired, there is provided a dummy bulb which bridges one pair of terminals without being active as a lighting unit. The delamping link dummy bulb is provided with a bank of series-connected capacitors connected between the power pins of the pair of terminals. The dummy link may also be used to replace a T12 bulb where the lumen output of the fixture is more than desired.
Claims7
A retrofit assembly for installing a high-frequency fluorescent lamp in a multi-bulb light fixture provided with first terminals for a first light bulb and second terminals for a second light bulb, the assembly comprising:
- a high-frequency fluorescent bulb configured with physical dimensions to fit into the multi-bulb light fixture for connection to the first terminals of the multi-bulb light fixture;
- a dummy bulb configured with physical dimensions to fit into the multi-bulb light fixture for connection to the second terminals of the multi-bulb light fixture, said dummy bulb having a bridging circuit connecting the second terminals to one another.
A delamping dummy bulb for installation in a multi-bulb fluorescent light fixture configured for T12 fluorescent bulbs, comprising:
- a first terminal having at least one terminal pin for connection to a power terminal of the light fixture, a second terminal having at least one terminal pin for connection to a power terminal of the light fixture, and a connecting body extending between and connecting said first and second terminals at a relative position corresponding to a relative position of first and second terminals of a T12 fluorescent bulb;
- a bridging circuit electrically connected between said terminal pin of said first terminal and said terminal pin of said second terminal, said bridging circuit including a plurality of capacitors connected in series between said first and second terminals.
