Our engineer visit our old customers in Switzerland for product maintenance

 

Jacky visited our Swiss client to do product maintenance when he do installation and training for new clients here. The customer purchased some products from LISUN before. Such as the Integrating Sphere & Spectroradiometer Test System, Goniophotometer, WT2080 LED Drive Tester, LS9956 Automatic Safety test system and so on. The customer was very surprised to our visit arrangements, said “How can you service so well!”We are also very pleased to get the customer's approval.

 

Below we share a few photos:

LISUN engineer Jacky visit new customers in Spain

 

Our engineer Jacky Jiang visit Spain to do installation & training for clients this month. And he also visited several local potential customers during this period.

 

This customer is a luminaires manufacturer, they are very interested in our LED test instruments. After learning that our engineer would do installation and training nearby, they arranged engineers to learn about the led test system in our client company and discuss with our engineer deeply here. After that, they warmly invited our engineer to visit their company.

 

Here are photos in their company:

LISUN Participate in the 2017 Hong Kong International Lighting Fair

LISUN Participate in the 2017 Hong Kong International Lighting Fair

 

The Hong Kong International Lighting Fair has become the largest industry exhibition in Asia, and the second largest in the world. LISUN participates this exhibition every year from 2011.

 

The huge quantity of buyers and exhibitors, as well as the constant innovation of the high volume achieve the industry’s prominent position of this exhibition. Our engineer met many customers here, and also met several experts in the lighting industry which laid a more solid foundation for our future development.

 

Here are a few photos of the exhibition:

What is the difference between IEC/ EN 60825-1 and IEC/ EN 62471?

What is the difference between IEC/ EN 60825-1 and IEC/ EN 62471?

 

IEC 60825-1: 2007 is a standard issued by the European Union, applicable to safety of laser products emitting laser radiation in the wavelength range 180 nm to 1 mm. Its scope of application would be only applied to LASER products after September 2010, and LED lighting products are no longer covered by the latest version of IEC / EN 60825-1, but need to be assessed in accordance with IEC / EN 62471.

IEC / EN62471 is a test standard for laser products (including LED) issued by the European Union. It is applicable to all lamps and lamp systems, including LEDs, incandescent bulbs, fluorescent lamps, gas discharge lamps, and arc lamps and other lamps and lamps, to evaluate the related light radiation hazards of different lamps and lamp systems. And it fully replaces the IEC / EN60825 standards on the LED product energy level requirements, and increases light biological requirements, including radiation intensity, radiance, etc. Moreover, it classifies product hazard levels according to the test data, Including the exemption level, low-hazard, medium-hazard, high-hazard level. The EU part of the standard EN62471: 2008 has been implemented in 2009.09.01 and EN60825 part of the LED will be completely invalid since 2010.09.01. EU Directive 244/2009 on energy efficiency requirements for non-directional lamps for domestic use also specifies that tests on UV content shall be carried out in accordance with IEC / EN 62471 (including energy saving lamps and incandescent / halogen lamps).

In the past, there is no detailed measurement and evaluation method for the harm to human body caused by optical radiation. The traditional test method is to evaluate the content of ultraviolet or invisible light contained in the light wave. When the LED appears, we evaluate it with the same IEC / EN 60825 standard for laser product. But now, LED products are no longer covered by IEC / EN 60825-1: 2007, but according to IEC / EN 62471 for risk assessment. And IEC / EN 60825 is only suitable for laser products. IEC / EN 62471 is covered by the CE Low Voltage Directive (LVD directive 2006/95 / EC) and is also covered by the Artificial Light Radiation Directive (AORD 2006/25).

This is a luminaries manufacture. They purchased a set of LSG-1200A Compact Goniophotometer and a M9822 DC Electronic Load from LISUN this time. This customer is very satisfied with our installation and training service, and praised that “LISUN is very professional!”

 

Thanks for your trust, LISUN would continue offering the best products and the best service in the future. Below is the group photo of the customer and our engineer:
