5、ED) Light Sources for Use in Lighting Products, UL 8750.86.8B If glass is used to render inaccessible live parts of the LED light source. The glass shall: Not be removable, or If removable, the accessible live part shall comply with the Class 2 or limiting impedancerequirements of UL 507, Section 25

6、89.6 The installation / use instructions for a ceiling suspended fan employing a integral LED light sourceshall include the word CAUTION and the following or equivalent statement: “The light source is designedfor this specific application and can overheat if serviced by untrained personnel. If any

7、servicing isrequired, the product should be returned to an authorized service facility for examination or repair.”RATIONALE FOR DECISION:LED luminaires provided as part of ceiling suspended fans differ from conventional incandescent andfluorescent light sources and therefore shall be additionally in

8、vestigated to determine their suitability in theceiling suspended fan. A current lack of standardization of LED light sources requires the source and hostceiling suspended fan to be investigated as a unit. LED light source requirements are specified in Outlineof Investigation for Light Emitting Diod

9、e (LED) Light Sources for Use in Lighting Products, UL 8750.Integral light sources are not considered to be replaceable. Consumer replacement of LED light sourceunits may result in misapplication of lighting controls and potential for overheating.UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER RE

10、PRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM UL LED light sources do not typically respond to conventional light dimming technologies. Theytherefore must be used in conjunction with controls specifically designed and intended for thepurpose. In addition, LED light sources require a means to con
