3 Components 3.1 Except as indicated in Clause 3.2, a component of a product covered by this Standard shall comply with the requirements for that component. See Annex A for a list of Standards covering components generally used in the products covered by this Standard. A component shall comply with the CSA or UL Standards as appropriate for the country where the product is to be used. 3.2 A component is not required to comply with a specific requirement that: (a) involves a feature or characteristic not required in the application of the component in the product covered by this Standard; or (b) is superseded by a requirement in this Standard. Electrical circuit components of an LED light source, including the LED itself, that are directly connected to line voltage are considered covered by the requirements of this Standard. 3.3 A component shall be used in accordance with its rating established for the intended conditions of use. 3.4 Specific components are accepted as being incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specified limits, and shall be used only under those specific conditions. 3.5 In Canada, a driver or part thereof providing an isolated output to an LED light source shall comply with applicable requirements of the Standard for Light Emitting Diode (LED) Equipment for Lighting Applications, CAN/CSA-C22.2 No. 250.13. In the United States, a driver or part thereof providing an isolated output to an LED light source shall comply with applicable requirements of the Standard for Light Emitting Diode (LED) Equipment for Use in Lighting Products, UL 8750.
7 Construction 7.1 Enclosures – General 7.1.1 Enclosures shall have the strength and rigidity required to resist the abuses to which they are liable to be subjected, without increasing the risk of fire, electric shock, or injury to persons due to a reduction of the required spacing for live parts or the loosening or displacement of live parts. 7.1.2 The enclosure material shall be metal or a polymeric material that complies with Clause 7.2. 7.1.3 A device shall be constructed so that it is not necessary to open or remove the enclosure during normal use or user maintenance. Parts that can be removed during normal use or for user maintenance such as cleaning or relamping shall not be considered to be a part of the enclosure. The incorrect replacement or discarding of such parts shall not affect the intended operation of the device. 7.1.4 A live part shall be contained within an enclosure. A part that is intended to be live at any time during the normal maintenance and use of a device shall be considered to be a live part. An enclosure shall comply with Clause 8.2.
6 Definitions 6.1 For the purpose of these requirements, the following definitions apply: 6.2 Accessible – able to be contacted by the articulate probe described in Clause 8.2.2. 6.3 Child-appealing feature – A feature that provides visual appeal and attraction to children in the form of shape, decoration, bright colors, or unusual illuminations. 6.4 Device – the general term used to denote all direct plug-in nightlights covered by this Standard. A more specific term is used if a requirement applies only to a certain type of device. 6.5 Direct Plug-In Nightlight – a nightlight with an integral parallel blade plug and a 10 W maximum light source, and which may incorporate a shade. It is used not for general illumination but for illuminating obstacles. For the purpose of this Standard, a nightlight may be referred to as “a device.” 6.6 Electroluminescent Panel – a solid phosphor layer, contained between two electrodes, that will emit light when subjected to alternating current. 6.7 Enclosure, Electrical – a part of the device intended to reduce the risk of contact with parts at hazardous voltage or hazardous energy levels. 6.8 Enclosure, Mechanical – a part of the device intended to reduce the risk of injury due to mechanical or other physical hazards. 6.9 Light Emitting Diode (LED) – a solid state component embodying a p-n junction, emitting optical radiation when excited by an electric current. 6.10 LED Light Source – a system comprising one or more LEDs along with the necessary circuitry that supplies the proper voltage and current or that is used to switch, dim or otherwise control the electrical energy to operate the LEDs.UL 1786-2021 pdf download.
