Three difference analysis of new and old national standard of LED lighting street lamp

Introduction: the national standard GB7000.203-2013 "luminaires - Part 2-3: Particular requirements for road and street lighting" was formally implemented in July 1, 2015, this standard will replace the standard GB7000.5-2005 street lamp has been used for 10 years. So, what is the difference between the new standard and the old one? Related enterprises and how to deal with it? The following will give you a detailed answer.

What is the difference between old and new standards?

Compared with the old standard, the new standard has the following three technical differences:

1, increase the maximum installation height marking requirements

The manufacturer shall specify the maximum installation height of the product in the lamp specification. When marking the height more than 5 meters, the lamp glass cover (if any) should meet the safety requirements of the standard clause 6.5.

2, modify the glass cover safety test requirements

The old standard only provides a test method for flat glass, and the new standard will also be incorporated into the scope of the assessment of glass, which means that the use of curved glass lamp shade also need to meet the safety requirements of glass cover.

The new standard compared with the old standard, added an optional conformity assessment mode, the way of the glass cover also meet the following two conditions: (1) using a pendulum or vertical drop hammer impact energy applied cover 5 joules of glass, glass can not be broken. (2) the impact head is used to break the glass, and the number of glass fragments in the square area with a side length of 50mm should be greater than 20.

In addition, the new standard for the old standard of qualified assessment methods have also been modified. In the old standard, the method of conformity assessment is that the number of glass fragments in the square area with the side length of 50mm should be greater than 60. The new standard requires only the number of glass fragments greater than 40.

Please pay attention to the difference between the requirements and the requirements in the second paragraph. More than 40 of the number of pieces of glass can be directly identified as qualified, and the number of fragments greater than 20 also need to meet the impact of the energy of 5 joules glass fragmentation requirements.

3, glass cover should be used in the thermal limit

The glass cover should be used under the glass manufacturer's thermal limit. The thermal limit shall include the minimum and maximum allowable temperature of the glass and the maximum t value.

After the implementation of the new standards, the relevant enterprises should do?

After the implementation of the new standards, the relevant enterprises should pay more attention to the safety performance of glass shade, in the actual use of the glass temperature changes should be ensured within the limits of heat. At the same time, it is necessary to use the glass with high safety, including curved tempered glass, to ensure that it can be broken into smaller pieces when it is broken, so as to reduce the harm to people.

After the implementation of the new standard, China Quality Certification Center is expected to be released in the near future version of the notice. Therefore, for CQC voluntary certification has obtained related products, manufacturers often should pay close attention to China Quality Certification Center website dynamic, timely completion of the certificate for version of the work, not because of negligence and the product certificate is in the state of failure.
