LED lighting products must enter the market for circulation or sell CCC certification. Because CCC certification is a compulsory product certification system (CCEE) of national safety certification. Import safety and quality licensing system (CCIB). China Electromagnetic Compatibility Certification (EMC) three-in-one CCC “authoritative certification is the China General Administration of Quality Supervision, Inspection and Quarantine and the National Certification and Accreditation Administration.” It is of irreplaceable importance as an advanced symbol that is in line with international standards.
This is a common problem in the certification of CCC safety requirements for LED lamps.
② Type of light source;
③Anti-electric shock protection level;
④ Shell protection grade;
⑤ Installation surface material. Covered by thermal insulation material;
⑥ Lamp control device; the above 6 points are the same, and those with similar structures can be divided into the same unit.
What are the led corn light forms of protection against electric shock?
Class I – basic insulation + protective earthing;
Class II – double insulation/reinforced insulation;
Class III – power supply voltage SELV + lamp operating voltage SELV
What positioning and protection measures should be taken at the power supply end?
The insulating pad is generally placed under the terminal block and fixed with double screws, so that the free conductor that may be taken out from the stranded conductor after wiring does not touch the metal part (power conductor) or live part (ground conductor).
What are the led corn light limitations of using self-tapping screws?
Self-tapping screws cannot be used to connect current-carrying parts unless there is a suitable locking device (such as a spring washer); self-tapping screws cannot be used to provide ground continuity unless there are at least two per connection.
How to tell which parts of the glass or translucent cover need to be impact tested according to the requirements of fragile parts?
After judging the removal of these parts, whether the IP of the lamp has reduced the protection level. Whether the protection against electric shock still meets the standard. Whether the protection against UV rays and light source sputtering hazard still meets the standard. If there is any negative judgment, it should be considered as a fragile part and subjected to an impact test.
