19.556.020 - Definitions.

For the purposes of this chapter only, the following words and phrases are defined as follows: Architectural floodlighting and outlining means the use of lighting to illuminate building facades, statuary, and similar edifices for appearance or other needs not involving visual tasks such as walking or driving. Artificial sky glow means anthropogenic light scattered in the atmosphere that on clear nights reduces the ability to see stars and the Milky Way. It also has negative environmental impacts. Community & Economic Development Director means the director of the Community & Economic Development Department of the City of Riverside or the person designated by the Community & Economic Development Director. Curfew means the time each night that lighting shall be dimmed or turned off in accordance with Title 24, Part 6, Section 130.2 for nonresidential lighting and Section 150.0 for residential lighting. Downlight means that the luminaire emits no light above 90 degrees relative to nadir. Fully shielded means a light fixture constructed and installed in such a manner that all light emitted by the fixture, either directly from the light source or a diffusing element, or indirectly by reflection or refraction from any part of the luminaire, is projected below the horizontal plane through the fixture's lowest light-emitting part. Glare means lighting entering the eye directly from a light fixture or indirectly from reflective surfaces that causes visual discomfort or reduced visibility. Light source means, in generic terms, a source of optical radiation (i.e., "light"), often called a "lamp", "bulb", or "tube". Examples include incandescent, fluorescent, high-intensity discharge (HID) lamps, and low-pressure sodium (LPS) lamps, as well as light-emitting diode (LED) modules and arrays. Light Trespass means light that falls beyond the property on which it originates. The amount of trespass is expressed in footcandles (fc) and is measured in the vertical plane at five feet above grade at the property line of the site on which the light(s) is located. If the adjacent property is a street, alley or sidewalk, then the point at which trespassing light is measured shall be the center of the street, alley, sidewalk, or right-of-way. Field measurements to determine light trespass compliance shall not include the effect of light produced by street lights. Lumen means the unit of measure used to quantify the amount of visible light produced by a light source or emitted from a luminaire (as distinct from "watt," a measure of power consumption). Luminaire means outdoor electrically powered illuminating devices, including a light source, outdoor reflective or refractive surfaces, lenses, electrical connectors and components, and all parts used to mount the assembly, distribute the light and/or protect the light source, whether permanently installed or portable. Maximum Lumens means the allowed maximum rated lumens per a photometric report or manufacturer's product literature for a dedicated fluorescent, LED or HID luminaire or the rated lumens of the light source installed for a line voltage socket luminaire or a low voltage socket luminaire. Shielded up-light means a luminaire aimed upward within 30 degrees of straight up that employs a baffle or louver to prevent glare. Temporary lighting means lighting that (a) employs a cord and plug that is not permanently wired and (b) is installed and removed when the temporary need is over, not to exceed 45 days, including but not limited to seasonal lighting. Outlining means exposed light sources attached to structures for the primary purpose of attraction, branding or decoration.
