A projectoror image projectoris an optical device that projects an image (or moving image) onto a surface, usually a projection screen. Projectors are now widely used in companies, schools, and other places. For projectors exported to the EU, CE certificationis requiRED to ensure that the product meets EU safety certification standards.
Projectors are electrical and electronic equipment. To ensure that products comply with EU standards, LVDand EMCdirectives must be used.
Some regulations and standards of projector LVDinclude:
(1) EN 60950– Information technology equipment, safety.
(2) Commonly required tests:
① Marking and description
② Low voltage test
③ Power cord tension test
④ Insulation test
⑤ Current test
⑥ Safe point test
The corresponding test items of projector EMCregulations are:
EN55022– Radiation test and conduction test (conduction and radiation test)
en61000-3-2– Harmonic test (harmonic current test)
EN61000-3-3– Flicker test (voltage fluctuation test)
EN61000-4-2– ESD Test (electrostatic test)
EN61000-4-3– RS test (radiation resistance test)
EN61000-4-4– EFT test (fast pulse anti-interference test)
EN61000-4-5– Surge test (surge test)
EN61000-4-6– CS test (conducted anti-interference test)
EN61000-4-8– PFMF test (power frequency magnetic field test)
EN61000-4-11– DIP test (pressure drop test)
The most common type of projector in use today is called a video projector. Video projectors are digital alternatives to earlier types of projectors, such as slide projectors.
① Throughout the 1990s and early 2000s, most early projectors were replaced by digital video projectors, but some places still used old-fashioned analog projectors.
② The latest type is a handheld projectorthat uses laser or LED to project images. If the ambient light is too strong, it may be difficult to see the projection.
Ensuring the safety of the projector is important for CE certification, which is recognized in the EU and internationally.
Note:
① If the projector has wireless transmission functionality, the RED directivemust be applied.
② Additionally, products may need testing and certification according to the RoHS directiveif necessary.
1. Submit the projector product certification application form
2. Provide technical informationof the projector product
3. CE certification body evaluates and tests the product content
4. Samples are sent to a testing institution
5. If tests are passed, the ce certificateis issued
