LED lamp beads are called LEDs of the light-emitting diodes. This is a general name. LED lamp beads use a low-voltage power supply, and the power supply voltage is between 2-4V. It varies from product. Therefore, it is a high-voltage power supply that drives it. The safer power supply is particularly suitable for public places. There are many detection methods often used in LED lamp bead test reports. Let's take a look.

What information does LED lighting equipment EN 62471 certification require?

1. Provide 2-3 sets of samples

2. Product use instructions

3. Material list (BOM table)

4. Application (form provided by the company)

5. How long is the circuit diagram and PCB diagram certification? Although EN62471 acknowledges that there is no clear valid stipulation, if the product changes or the regulations are updated, the EN62471 certification requires the corresponding change cost to meet the requirements of the exporter.

LED lamp bead quality inspection method Type -type test. The inspection products comply with technical specifications such as quality level, performance, safety requirements, environmental conditions, etc., and are applicable to their regulations.

2 Normally test (also known as shipping test). Check the product materials and processing quality defects, and check the inherent performance of the product, including functional tests and security test items.

3 Sampling test. If the relevant product benchmark has this requirement, the test is also used to verify the performance and characteristics specified by the product. These regulations may be proposed by the manufacturing plant or negotiated with the manufacturing plant with users.

4 Special exams. According to relevant product standards and manufacturers and user consultations, they can meet the various needs of market products. Flame retardant testing, solar radiation, light aging, etc.;
