15.33 Partially Shielded (Light Fixture). A light fixture constructed and mounted
such that most light emitted by the fixture, either directly from the lamp or a
diffusing element, or indirectly by reflection or refraction from any part of the
fixture, is projected below the horizontal. Light emitted at or above the horizontal
direction (sideways or upwards) arises only from decorative elements or strongly
colored or diffusing materials such as "honey" or colored glass or plastic. Fixtures
using spot or flood lamps are considered partially shielded if the lamps are
aimed no higher than 45 degrees above straight down (half-way between straight
down and straight to the side).

15.39 Sign, Multicolor Fixed-Copy LED. A sign composed of LEDs of more than
one color with a fixed (not changeable or programmable) copy display.
15.40 Sign, Neon. A sign including luminous tubes formed into text, symbols or
decorative elements and directly visible from outside the sign cabinet.
15.41 Sign, On-Site Advertising. A sign used primarily to advertise goods or
services offered on the same parcel on which the sign is located. Such a sign

temperature; does not include publicly owned signs providing general interest
information exclusively (such as road names or highway conditions)
15.42 Sports Class I/II/III/IV. Level of sports play as defined by the Illuminating
Engineering Society of North America. This level is primarily determined by the
number and distance of spectators; the higher recommended illumination levels
facilitate the spectator's ability to view the action. Sports Class IV is the most
common level, and is typical of municipal and amateur league and social level
sports, with minimal accommodations for spectators, typically including bleachers
located close to the field. Sports Class III includes increased accommodation
for spectators. Sports Class II and Sports Class I apply to large sports facilities
where thousands of spectators may be located hundreds of feet from the field,
and television broadcasting may be a consideration.
15.43 Spot Lamp. A specific form of lamp designed to direct its output in a specific
direction (a beam) with a reflector formed from the glass envelope of the lamp
itself, and with a clear or nearly clear glass envelope: Such lamps are so
designated by the manufacturers, and typically used in residential outdoor area
lighting (Figure 15.43).
