Other than the composition of the arc tube, the construction of the high-pressure
sodium lamp is essentially the same as the mercury and metal halide lamps.
Hazards and precautions There are few unique hazards during manufacturing of

The highest-efficacy general-purpose HID source available is the high-pressure
sodium lamp (HPS). The basic construction of this type of lamp (also designated
SON) is illustrated in Fig. 12.27, which shows schematic drawings of the design.

Electrical Engineer's Reference Book
The requirements for efficient operation of a sodium lamp are: (1) the arc voltage
gradient must be low (long are tubes for a given power), and (2) the current
density must be low (arc tubes must have a large diameter). Sodium vapour
readily ...

"The 18-watt low-pressure-sodium lamp actually burns 30 watts an hour
including ballast losses. If it were lit an average of 1 1 hours a night, 365 nights a
year, it would use about 120 kWh per year; the 150- watt incandescent, about
600 kWh.

A review of Table 14-1 would indicate that the low-pressure sodium lamp is
preferred. when power only is considered; the high-pressure sodium lamp is
second; and the metal- halide lamp and the high-output fluorescent lamp are tied
for third.

34 1.3.7 High-Pressure Sodium Lamp In both, the low-pressure (LPS or SOX, SOI
, or SO/H) and high-pressure sodium discharge lamp (HPS or SON), the
resonance lines at 589.0 and 589.6 nm play a central role (sodium D-lines).

The discharge in the high pressure sodium lamp operates in an atmosphere of
sodium, mercury, and a rare gas, usually xenon. The polycrystalline alumina
envelope can operate as high as 1300°C with very little reaction with the sodium

A high-pressure sodium lamp contains a sealed polycrystalline alumina arc tube
with two niobium electrode feedthroughs enclosed in an evacuated glass lamp
jacket. A schematic diagram of the arc tube is shown in Fig. 1. A pellet of sodium

Successive flares are neither the same duration nor amplitude, nor (and this is
the important part) are they smooth continuations of one another. Figure 2.12
shows the small-scale structure of a ray from, say, a sodium lamp, which we will ...
