26、HORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the common UL and ULC Standard for Holders, Bases, and Connectors for Solid-State (LED) Light Engines and Arrays. It is the First edition of both CAN/ULC-S8754 and ANSI/UL 8754. This Joint Standard was prepar

27、ed by Underwriters Laboratories Inc., ULC Standards, and the Technical Committee on Field-Replaceable LED Light Engines. The standard was formally approved by the UL/ULC Technical Committee on Field-Replaceable LED Light Engines. The efforts and support of the Technical Committee are gratefully ackn

28、owledged. Only metric SI units of measurement are used in this Standard. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The rst stated value is the requirement. In Canada, there are two official languages, English and French. All

29、 safety warnings must be in French and English. Attention is drawn to the possibility that some Canadian authorities may require additional markings and/or installation instructions to be in both official languages. Annex A and Annex B, both identifed as normative, form a mandatory part of this Stan

30、dard. Note: Although the intended primary application of this Standard is stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of Harmonization This Standard is published as an identi

31、cal standard between UL and ULC Standards. An identical standard is a standard that is the same in technical content except for conicts in Codes and Governmental Regulations. Presentation shall be word for word except for editorial changes. Interpretations The interpretation by the SDO of an identic

32、al or equivalent standard shall be based on the literal text to determine compliance with the standard in accordance with the procedural rules of the SDO. If more than one interpretation of the literal text has been identied, a revision shall be proposed as soon as possible to each of the SDOs to mo

33、re accurately reect the intent. UL Effective Date A UL effective date is established by Underwriters Laboratories Inc. and is not part of the ANSI approved standard.

34、ISSION FROM UL 1 Scope 1.1 This standard species the requirements applicable to holders, bases and connectors intended for solid-state (LED) light engines and arrays for installation in lighting equipment, provided that they employ a conguration not typically found on incandescent or uorescent light

35、 sources. 1.2 This standard does not cover lampholders with screw, bayonet or pin-type bases intended to be compatible with incandescent or uorescent lamps. Such lampholders are covered under CSA C22.2 No. 43 / UL 496. 1.3 This standard does not cover wire connectors. Such connectors are covered und

36、er CAN/CSA-C22.2 No. 65 / UL 486A-486B or CSA C22.2 No. 2459 / UL 2459. 2 Denitions 2.1 For the purpose of this standard, the following denitions apply: 2.2 BASE That part of a lampholder that is used for mounting of the device. 2.3 CURRENT-INTERRUPTING DEVICE A component (such as a switch or breake

37、r) intended to stop the ow of current in a lampholder circuit. 2.4 ENCLOSURE That part or parts of a lampholder that: a) Renders inaccessible all or any parts of the equipment that may otherwise present a risk of electric shock, or b) Retards propagation of ame caused by electrical disturbances occu

38、rring within. 2.5 INSULATION, BASIC The insulation necessary to provide basic protection against the risk of electric shock. This insulation may be in the form of vulcanized ber, an inorganic or polymeric material, or an air gap. 2.6 INSULATION, DOUBLE An insulation system comprised of both basic in

39、sulation and supplementary insulation. 2.7 INSULATION, REINFORCED A single insulation system with such mechanical and electrical qualities that it, in itself, provides the same degree of protection against the risk of electric shock as does double insulation. Note: The term “single insulation system

40、” does not necessitate that the insulation must be in one homogeneous piece. The insulation system may comprise two or more layers that cannot be tested as supplementary or basic insulation. 2.8 INSULATION, SUPPLEMENTARY An independent insulation provided in addition to the basic insulation to provi

41、de protection against the risk of electric shock in case of breakdown of the basic insulation. 2.9 LAMP BASE The part of a lamp that engages the lampholder and makes contact with the electrical circuits of the lampholder. 2.10 LAMP CONNECTOR A type of lampholder that provides electrical connection t

42、o a lamp but does not provide mechanical support; sometimes known as a lamp-supported lampholder.

43、onnection to the electrical circuits of a lamp and, in some cases, providing support. 2.12 LAMPLOCK A feature intended to keep a lamp from being removed except by a person having a key or special tool. 2.13 LED ARRAY (LED MODULE) An assembly of one or more LED packages or dies on a printed circuit b

44、oard or substrate, possibly with optical elements and additional thermal, mechanical, and electrical interfaces that are intended to connect to the load side of an LED driver. 2.14 LED LIGHT ENGINE (LIGHT ENGINE) An integrated assembly comprised of an LED array (LED module), LED driver, and other op

45、tical, thermal, mechanical and electrical components. The device is intended to connect directly to the branch circuit through a custom or industry-standard lamp base. This lamp base shall be of a type not typically found on incandescent or uorescent light sources. a a With permission from ANSI/IES
