Description
PHA 21517 1 28.03.1990 Four lamp fluorescent wiring arrangement.
This is an invention in the lighting art. More particularly, it involves a simplified wiring arrangement for a four lamp fluorescent fixture~
This invention is related to that disclosed in our concurrently filed patent application entitled rFour Lamp Fluorescent ~allast Means~ assigned to the same assignee as this application. The disclosure therein is incorporated by reference herein.
One of ~he objects of the invention is to simplify the wiring of a four lamp rapid start fluorescent fixture.
An advantage of the invention is that a considerable amount of wire is saved in such a four lamp rapid start fluorescent fixture over earlier such fixtures.
Another advantage of the invention is that it lends itself to the use of fixed connections in association with lamp ballasts.
One of the features of the invention is the use of part of the ballast means of each half of the fixture in the other half of the fixture.
In carrying out the invention there is provided a four lamp rapid start fluorescent wirinq arrangement with two ballast means.
Each ballast means is associated with a pair of lamps. Each ballast means includes three pairs of lamp wires. The improvement is that one of the three pairs of lamp wires of each ballast means is not connected to its associated pair of lamps but is connected to the pair of lamps associated with the other ballast means.
Other objects, features and avantages of the invention will be apparent from the following description and appended claims when considered in conjunction with the accompanying drawing in which:
Flgure 1 is a wiring diagram of a previous type four lamp rapid start fluorescent unit;
Figure 2 is the typical physical layout arrangement for the lamp unit of Figure 1;
Figure 3 is a wiring diagram of the improved four lamp ~` 2023193 PHA 21517 2 28 03.1990 rapid start fluorescent unit; and Figure 4 is the improved physical layout arrangement according to the invention.
Shown in Figure 1 are two pairs of fluorescent lamps A1 and A2 and B1 and B2. Each lamp is a straight elongate tube with filaments at each of its ends. Each pair of lamps has its own respective ballast means A and a. Each ballast ~eans includes a primary winding PRA, PRB and an associated secondary winding SEA, SEB. Each primary winding is connected across a source of voltage provided across line BL and its ground return WH. Operating voltaqe for each of the pairs of fluorescent tubes is provided along red lines REA, RE~.
Voltage for lower filaments (as shown in Figure 1) is provided by blue lines BLUA and BLUB. The adjoining electrodes of each pair of tubes is provided with voltage along yellow lines YEA and YEB.
Capacitors CSA and CSB serve as the well known starting capacitors while capacitors CA and CB contribute to the ballast impedance. All of the foregoing is by way of background information, it being well known to those skilled in the fluorescent lighting art.
Shown in Figure 2 is a typical physical layout for the circuit shown in Figure 1. Appearing therein are the power supply lines B~ and WH. All the rest of the lamp wires shown are shown as single wires although it is to be understood that each in fact represents a pair of lamp wires. As can be seen ballast A is connected to lamp Al by blue wires BLUA and is connected to lamp A2 by red wires REA. Both the blue wires and the red wires emanate from one end of ballast A.
Emanating from the other end of ballast A are yellow wires YEA. These are connected to the other ends of fluorescent tubes A1 and A2.
~ikewise, ballast B has blue wires BLUB and red wires REB emanating from one of its ends and connected to lamps B1 and B2, respectively.
Emanating fro~ the other end of ballast B are yellow wires YEB which are connected to the other ends of lamps B1 and B2. This has been a standard connecting practice in the fluorescent lamp business for approximately 35 years.
A~l of the objects, features and advantages of the invention will be clear from a comparison of Figures 3 and 4 with Figures 1 and 2. In this respect it will be seen that yellow wires YEA
from the heater coils of ballast A are not connected to filaments of 2~23193 PHA 21517 3 28.03.1990 tubes A1 and A2 but rather are connected to the filaments of tubes 81 and ~2. Likewise yellow wires YEB from ballast means ~ are connected to the filaments of tubes A1 and A2. From Figure 4 it can also be seen that the yellow wires now emanate from their respective ballast means through the same sides as the blue and red wires. This is in contrast to the manner in which they used to emanate from their respective ballast means, that is, at the ends opposite from which the blue and red wires emanated.
By the aIrangement of this invention each pair of yellow wires in a four foot fluorescent fixture has been shortened from 36 long to 12 inches.
It should be apparent that various modifications of the above will be evident to those skilled in the art and that the arrangement described herein is for illustrative purposes and is not to be considered restrictive.
