Technical points on the detection of LED energy-saving lamps in North America

First, the status quo of North American LED standards

LED energy-saving lamps as a new type of products, the current North American product safety standards do not specifically address the technical requirements of such products, LED product testing has become a topic in the industry. For the current industry situation, UL Labs of the United States is organizing the preparation of LED energy-saving lamp safety certification standard UL8750, which is still drafted and has not been officially adopted as the certification standard. Therefore, the certification test problem of LED energy-saving lamps has not been completely solved.

The basic principle of the LED energy-saving lamp is to convert the AC power to DC power through the switch-type power module to supply power to the LED. According to the basic principle and structural characteristics of LED energy-saving lamps, MET Labs of the United States proposes a transitional detection scheme at the present stage: the US certification standard UL1993 (corresponding to the Canadian standard CAN/CSA-C22.2No.0, CAN/ CSA-C22.2No.74), and power module standard UL1310 or UL1012 (corresponding to Canadian standard CAN/CSA-C22.2No.107) test and certification of LED energy-saving lamps.

Second, the technical points in the test

The following is a description of the key issues in the LED energy-saving lamp certification test based on the UL1993, UL1310 and UL1012 standards.

Material

The LED energy-saving lamp can be made into various shapes. For example, the fluorescent tube type LED energy-saving lamp has the same shape as the ordinary fluorescent tube, and the power module and the light-emitting diode are enclosed by the tubular transparent polymer casing of the fluorescent lamp. The transparent polymer housing provides fire and shock protection in the product. According to the standard requirements, the energy-saving lamp housing material must reach the V-1 level or above, so the transparent polymer housing must be made of V-1 or higher. It should be noted that the product casing must meet the required V-1 rating, and its thickness must be greater than or equal to the thickness required for the V-1 grade of the raw material. The fire rating and thickness requirements can be found on the UL yellow card of the raw material. . In actual testing, it was found that in order to ensure the brightness of the LED lamp, the manufacturer often made the transparent polymer casing thin, which required the inspection engineer to ensure that the material meets the required thickness of the fire rating. Since different raw materials have different thickness requirements for the same fire rating, some raw materials can meet higher fire rating requirements at a lower thickness. It is recommended that the manufacturer can select the appropriate raw material for the product casing.

This cable is one of the Control Cable and it is with OFC copper conductor insulated and sheathed by PVC material. This cable may be used in dry or wet places and widely applied to transmit and distribute low voltage electrical power, data or signal. there have optional choices of flexibility and screen material to fit for installation as request. Some control cables can bear larger mechanical forces. Some of them is with shielding and flame retardant performance.
