33). By using a specially programmed microprocessor, the voltage
and current supply to the lamp can be controlled in many steps
between turn on and normal running conditions (col. 7,
lines 4-9). In addition, the controller can also measure lamp
light output, its color temperature, and its actual temperature
(col. 7, lines 39-45).
Gaus is directed to a metal halide arc discharge lamp (col.
1, lines 6 and 7). As stated by the examiner (answer, page 5)
gas discharge and metal halide lamps are known in the art as high
intensity discharge lamps. Although Gaus does not disclose the
metal halide arc discharge lamp to be a HID, we take Notice3 that
high-intensity discharge (HID) is a term denoting a general group
of lamps consisting of mercury, metal halide and high-pressure
sodium lamps. A mercury lamp is an electric discharge lamp.
Metal halide lamps are very similar in construction to the
mercury lamps, the major difference being the addition of a metal
halide in the arc tube. Because the metal halide lamp of Gaus
and the gas discharge lamp of Cockram are both HIDs and are very
similar in construction, we consider the references to be of
analogous art, and find that an artisan would have been motivated
