North American LED energy - saving lamp detection of technical requirements

- Apr 06, 2017-

First, the status of LED North American standards

LED energy-saving lamps as a new product, the current North American product safety standards are 

not specifically for the technical requirements of such products, LED product testing has become a 

subject of the industry. US UL laboratory for the current situation in this industry, is organizing

 the preparation of LED energy-saving lamp safety certification standards UL8750, this standard is

 still draft, not formally adopted as a certification standard. Therefore, the LED energy-saving 

lamp certification test problem, has not been completely resolved.

The basic principle of LED energy-saving lamps is through the switch-type power supply module will 

be converted to direct current AC power to the light-emitting diode to work. According to the basic

 principles and structural characteristics of LED energy-saving lamps, the United States MET 

laboratory proposed a transitional testing program at this stage: the use of traditional energy-

saving lamps US certification standards UL1993 (corresponding to the Canadian standard CAN / 

CSA-C22.2No.0, CAN / CSA-C22.2No.74), and the power module standard UL1310 or UL1012 (corresponding

to the Canadian standard CAN / CSA-C22.2No.107) on the LED energy-saving lamps

Second, the detection of technical points

The following based on UL1993, UL1310 and UL1012 standards, LED energy-saving lamp certification 

test key issues, do some elaboration.


2. Drop test

3. Dielectric strength

4, power module

5. Insulation requirements

6. Temperature rise test

7. structure

8. Fault test

Third, the factory inspection

North American product certification to the factory inspection, factory inspection, including the 

first factory inspection and follow-up inspection. If the factory is the first time to apply for 

North American product certification, will have to conduct the first factory inspection. The first 

factory inspection is mainly for the factory quality assurance system, requiring the factory has a 

perfect quality assurance system to ensure that the product quality is effectively regulated and 

guaranteed. If the factory has been established according to ISO9000 quality management system, 

and passed the ISO9000 certification, basically can meet the requirements of the first factory 

inspection management system. If the factory does not pass the ISO9000 certification, it will have 

clear procedures in the aspects of raw material procurement, incoming inspection, inventory 

management, product design, engineering change, production line test, instrument calibration and 

complaint follow-up. Follow-up inspection is mainly for product structure inspection and production 

line product testing and so on to ensure that the production line of the product structure and 

certified samples consistent, and through the relevant production line test. After the product has 

passed the test certification, the manufacturer must strictly follow the structure of the certified

 sample and the component list to produce the product. Any changes that may involve the safety of 

the product must be notified to the certification body for evaluation. If necessary, it is possible

to carry out re-testing and reporting changes. The test report of the product has a clear requirement

for the production line of the product. The manufacturer must perform the relevant tests as 

required, such as high voltage test and ground continuity test.
