3 Definitions The following definitions apply in this Standard: Air-handling luminaire – a luminaire designed and intended to connect directly to duct work fabricated specifically to handle environmental air as the primary purpose. Baffle – a part of a luminaire that allows air passage but limits the emission of flame, arcs, or molten material from exiting the enclosure. Ballast – in Canada and the United States, a device that by means of reactance or resistance, singly or in combination, limits the current of a lamp to the required value for proper operation and, where necessary, provides adequate starting voltage. In the case of rapid start circuits, it provides voltage for low-voltage lamp filament heating. Ballast (MEX) – in Mexico an electromagnetic, electronic, or hybrid device that, through inductances, capacitances, resistances, and/or electronic elements (transistor, thyristors, etc.), alone or in combination, limit the lamp current, and, when necessary, the starting current and voltage. The electromagnetic and hybrid ballast has the same output frequency as the mains (60 Hz). Electronic ballasts are those that have at least one frequency converter.
Canopy – a plate or similar fitting intended to provide a cover over an outlet box. Canopy, drop – a canopy that can be lowered for access to the supply connections without lowering the luminaire. The canopy does not support the luminaire. CEC – Canadian Electrical Code, Part I. Cellulosic – a paper or wood type product that is treated or processed. Examples include insulation, paper, and fiber. Circuit, Isolated Low Voltage Limited Energy (LVLE) – a circuit supplied by a source with no direct electrical connection between input and output, such as provided by a transformer or optical isolator, and with output parameters as follows: source with a maximum output voltage of 42.4 V peak ac (30 V rms) or 60 V dc, and a maximum output current limited to: a) 8 Amps for 0 to 42.4 V peak ac, or 0 to 30 V dc; or b) 150/VA, for a voltage between 30 and 60 V dc. Comply with – a term to denote that the requirements specified for the construction or material have been fulfilled by a) conducting a specified test; b) confirming that a specified test has been conducted on the same or similar construction or material; or c) determining by an engineering evaluation that equivalent, or greater, acceptable compliance has been demonstrated.
Conductor, insulated – a conductor encased within material recognized as electrical insulation. Conductor, neutral – the identified grounded conductor, referred to as “the neutral”. Cord set – a length of flexible cord having an attachment plug at one end and a cord connector at the other end. Decorative part – a part of the luminaire, outside the enclosure, that has no safety function. Diffuser – a device to redirect or scatter the light from a source, primarily by the process of diffuse transmission. Electrical spacing – the minimum distance, measured through the air or over an insulating surface, between an uninsulated live part and ground or between uninsulated live parts of opposite polarity. Electric-discharge lamp – a lamp in which the light (or radiant energy near the visible spectrum) is produced by the passage of an electric current through a vapor or gas (e.g., a fluorescent or HID lamp, such as metal halide, sodium vapor, and mercury). Enclosure, electrical – a part of the luminaire intended to reduce the risk of electric shock.UL 1598 pdf download.
