Our company is now going to do UL certification for LED panel lights, and I don t know which certifi

You can find UL Meihua, or you can find a UL authorized ** agency, but remember to prepare the information when applying for UL, such as:

Application form, product information (model, parameters, **, certification information of the drive power supply), etc.

LED application for UL certification is more expensive, are you sure to do it?

You can find Shanghai Quake to do it, they are UL accredited lighting laboratories, and the pass rate is very high.

You can contact the UL representative office directly.

For example, Suzhou UL Meihua.

Our company has cooperated with state agencies, with diverse and flexible choices. Interested in contacting. QQ has been sent to you.

The safety requirements of the U.S. market for LED lighting products mainly include UL, ETL, CSA, MET, CTUVUS and other certifications. The main certification test standards are UL 8750, UL 1598, UL 153, UL 1993, UL 1574, UL 2108, UL 1310, UL 1012 and UL 60950-1.

Among them, UL 8750 is a safety requirement for the use of LED light sources in lighting products, including requirements for the use environment, mechanical structure, electrical mechanism, etc. In terms of test evaluation, the main tests of UL 8750 are: test evaluation related to electric shock hazard, test evaluation related to thermal hazard, test evaluation related to mechanical and electrical structures, test evaluation related to energy hazards, material evaluation related to fire protection, test evaluation related to the application environment, etc.

UL 1598 is a safety requirement for fixed lamps and lanterns that do not have power cord plugs, including step lights, ceiling lights, chandeliers, wall lights, street lights, bollard lights, etc.

UL 153 is a safety requirement for portable lamps and lanterns with power cord plugs, including hand lamps, cabinet lamps, table lamps, floor lamps, etc.

UL 1993 is a safety requirement for self-ballasted lamps and lamp adapters that contain driver circuitry such as LED bulbs, compact fluorescent CFLs, etc.

UL 1574 and UL 2108 are safety requirements for tunnel lighting systems and low-voltage lighting systems, respectively.

UL 1310 is for power supplies** with a Category 2 safety loop, while UL 1012 is for power supplies without a Category 2 safety loop.

UL 60950-1 specifies power supplies** with LPS safety loops.

UL 8750 is a mandatory test item for LED lighting products, and according to the category of the product and the category of the power supply, it is necessary to increase the testing items of the corresponding lamps and power supply standards. For the safety testing and certification of LED lighting products, the focus of the EU CE certification and the US UL certification is different, CE certification focuses on the safety of the product against electric shock, while UL certification focuses more on the fire safety of the product.

Xiamen Puwei photoelectric lamps are good, and they are exported to Japan and rank first in the country. More than 4,000 models of tube and tube lamps are UL or ETL certified.

Puwei photoelectric high luminous efficiency LED tube.

Puwei Optoelectronics Japanese patent.

Puwei optoelectronic production base.

I seem to know that, too! Shenzhen Lei Peng Optoelectronics' lamps, bulb lights, ceiling lights, downlights, etc. have passed the certification, you can also find a way to contact it!

Shenzhen Jinshidun Lighting Technology ****.

I know that the lamps and bulbs of Puwei Optoelectronics Technology have passed the UL CE RoHS certification, you can find a way to contact us.

Generally, the UL certification standard for LED tubes is: UL1993 + 8750 + 1598C series: as long as it is LED tubes, they can be put together, but according to the actual selection of multiple main test models, the corresponding cost will also increase!

Creepage distance at least, if the product is non-isolated, must be fiberglass!

It must be designed as a mechanism with one end of power supply and the other end of the open circuit.

The plastic casing is at least V-0 fireproof.

The thickness of the metal case is, at least.

The lamp should not exceed 500g

Lamp testing couldn't be easier:

1.Enter the test.

2.Lamp head size test.

3.Withstand voltage test (metal shell) Failure can only change the structure!

4.Leakage current test (usually the problem is in a metal case).

1. ** formula: about 1 week.

2. It takes about 1 week to make timely payment and sort out the data.

3. Witness test: 1 week.

4. After the witness test is completed, there is no problem, and the factory will be inspected in about 1 week.

5. The factory inspection is issued through the certificate. (about 5 weeks in total).

Information required to apply for ETL certification:

1. Circuit schematic diagram (please note that the parameters must be consistent with those on the nameplate and manual).

2. Printed circuit layout and part location diagram.

a. Products with electronic circuits must be provided.

b. If electronic switches, dimmers and other electronic components have been certified, this item can not be provided.

3. English manual (the manual must have the name or trademark of the manufacturer, model, parameters, installation method and necessary safety warnings.) ）

The following are listed with fixed luminaires:

Second: Structural assessment.

1. Creepage distance: If the output power of LED drive is greater than 100W, then the distance from the aluminum substrate copper foil (including solder joints) to the metal shell is at least.

2. The thickness of the metal shell is at least.

Third: the information and samples required for UL certification.

Materials: list of model differences, schematic diagram of aluminum substrate (several strings and several parallel drawings), silk screen drawing of aluminum substrate, lamp bead specification, component size drawings (including shell, lens, aluminum substrate, etc.), label style, product manual, list of key components.

If the LED driver is not certified, then the driver circuit schematic and silk screen diagram need to be supplemented.

1. Input test: The test value is required to not exceed +-10% of the customer's nominal value.

The test is relatively easy to fail, and the rectification plan after the failure: the customer rectifies the product and adjusts the power; Or directly use the measured value to determine the nominal value of the product.

2. Ground resistance test: generally will not fail.

3. External power cord (18AWG) tension: 156N force test for 1min, power cord can not be pulled. In case the test fails, it can be rectified by tying the power cord in a knot.

4. Impact test: The steel ball can not touch the live parts or creepage distance after hitting the sample. The test generally does not fail.

5. Stress relief test: the product is baked at a certain temperature for 7 hours, and there will be no problem in general.

6. Temperature rise test: the test will generally not fail, in case of failure, the customer only has to modify the product information, with a better temperature resistance of the information; or rectify the sample and reduce the power; or glue potting (generally 10° lower). There is no other way.

7. LED lamp bead short circuit test: generally there will be no problem.

8. If it is used outdoors, then you need to do a rain test, the test is easy to fail, in case of failure, only rectification samples.

If it is a waterproof rubber ring + glue, it needs to be noted on the manual that it cannot be repaired, and it can only be returned to the factory for maintenance.

9. Tidal test: generally there will be no problem.

10. Withstand voltage test: plastic and glass shell play 2500V, generally there will be no problem; The metal shell generally has to play about 3500V, in case of failure, the only way to change the structure is to change.

11. Lifting weight test: generally there will be no problem Consider whether the hardness of the installation frame is enough?

1.Enter the test.
