Definitions
- the present invention constitutes an improvement over prior art U.S. Pat. No. 4,431,948, issued Feb. 14, 1984, and also over US patents No's. 5.528,110; 5,508,589; and 5,623,186, the disclosures of which are incorporated herein by reference to the extent necessary for a full disclosure and understanding of the present invention.
- the '948 patent discloses a controller for HID lighting effecting a selective reduction of applied voltage by use of an autotransformer connected in series with a switch.
- a first portion of the autotransformer winding is interposed between the input and the output, and an additional winding portion is interposed between the output and the common or neutral terminal of an alternating current power source.
- the first portion of winding is referred to the series winding of the autotransformer, and the second portion of the winding is referred to as the common winding of the autotransformer.
- the switch (which may be implemented as a relay, for example), is connected in series with the common winding so that when the relay is in its open condition, no current flows in the common winding, and the output voltage is substantially equivalent to the input voltage.
- the warm up time interval for the HID light unit may vary dependent upon ambient temperature; and to a lesser extent, dependent upon wind speed. It is a further object that this invention provide a HID lighting controller which reduces the operating voltage to a HID light unit only after the HID light unit has achieved a sufficient operating temperature to sustain operation at the reduced voltage level.
- FIG 1 diagrammatically illustrates one embodiment of an improved lighting controller apparatus for HID lighting
- the lighting controller 10 includes a generally rectangular box or case, 18 defining an interior cavity 20. Disposed within the cavity 20 is a printed circuit board 22, which is supported by means of standoffs 24. A connector strip 26 is carried adjacent to one edge of the printed circuit board 22 in order to facilitate connection of electrical wiring to the apparatus 10. This connector strip 26 also provides for connection of the circuitry (to be further explained below) which is disposed on the printed circuit board 22.
- thermal insulation surrounding the thermal analog device 36 in recess 36'; and an environmental cover which spans the space between the pair of transfo ⁇ ners 28, 30, and over the pair of relays 32, 34. That is, the environmental cover (indicated in Figure 3 by the dashed line 36") spans across recess 36' just above the device 36, and forms an upper boundary wall above the device 36' in the same way the printed circuit board 22 forms a lower wall to the recess 36'.
- the space around the thermal analog device 36, and between the PC board 22 and environmental cover 36" is filled with a selected amount of thermal insulation, such as with fiberglass insulation.
- the thermal insulation and environmental cover about device 36 are further depicted and described below, but it is sufficient for now to understand that their purpose is to provide a protected and thermally controlled environment about the thermal analog device 36.
- this secondary winding 46 is connected to the wire 40.
- the transformer 44 functions as a conventional autotransformer, and delivers a reduced voltage to the lighting unit 14.
- the relay 28 or 30 provides power from wire 38 to the first end of winding 46.
- the relay shorts the primary winding 42, but delivers full voltage from wire 38 to the lighting unit 14.
- the device 36 further includes a thermal mass, indicated by the arrow 50 (providing a warm up time constant), and a temperature responsive switch, indicated with the numeral 52. While it will be noted in the presently preferred embodiment that the temperature responsive switch 52 is normally closed, the invention is not so limited. That is, the device 36 could employ a normally open temperature responsive switch, and then would reverse the connection of the NO and NC contacts of the relays 28 and 30.
- the desired and intentional slowness of the time constant for warming up of the thermal analog device 36 can be employed, for example, to insure that the HID light unit reaches its operating temperature despite windy conditions (which carry heat away from the HID light unit) before voltage is reduced by the controller 10. Thus, continued operation of the HID light unit once operating voltage is reduced by the controller 10 is assured.
- the thermal analog device 36 will likewise warm up from ambient temperature.
- the thermal analog device is used to determine when the lighting unit 14 is sufficiently hot to sustain operation at reduced voltage.
- the switch 52 of the thermal device 36 is closed, and provides power to the coil of the relay 28 or 30. So, the NC contact of this relay 28 or 30 is opened, and the NO contact is closed. As a result, the coil 42 is shorted, and the HID lighting unit 14 immediately receives full line voltage (from wire 38, viewing Figure 4), which is sufficient to start the HID lighting unit 14 even in cold ambient conditions.
- the modular voltage reduction apparatus 58 of the present invention is configured to be interposed between the ambient light sensor 60 and the receptacle 62 of the lamp structure 56 More specifically, as seen in Figure 8, the voltage reduction apparatus 58 provides a receptacle 64, which is a duplicate of the receptacle 62 of the lamp structure 56.
- the circuit of Figure 9 is essentially the same as that indicated on Figure 8, with the exception that the connection from plug 66 to the primary winding 142 is made at the tap 142a, rather than at the end of this primary winding 142.
- the result is that when the operating voltage to the controlled street light is reduced from full voltage to some lower selected operating voltage, the voltage reduction effected by the embodiment of Figure 9 is twice that effected by the embodiment of Figure 8.
- the apparatus of Figures 8 and 9 are the same with the exception of the connection between transformer 142 and the plug 66. Accordingly, it is apparent that a user of the apparatus 58 of Figures 8 and 9 may select the voltage reduction desired for sustained operation of the street light 56.
- a countdown timer may be included in the circuit elements 84.
- This tie rod 86 is secured by a pair of screws 88, 90, which each threadably engage into respective axially extending holes defined by the rod 86, so that the closure member, as well as the circuit element contents of the controller 58, are retained in the housing 58' including cup-shaped housing portion 68.
