The Report of the 2nd Meeting of

ISA Technical Committee on Standardization (TCS2)

 

The 2nd Meeting of the ISA Technical Committee on Standardization (TCS2) was held on November 6th, 2012 at Westin Hotel, Guangzhou, China, which was attended by over 20 representatives from research initiatives, corporations, and organizations, including Cree, Philips, Osram, CSA, Semileds, Instrument Systems, Kaneka, Sanan Optoelectronics, Kaneka Trading, APT, Tsinghua UPDI, Fraunhofer IZM, Zhejiang University, Visionox, HKUST LED-FPD Technology R&D Center at Foshan, University of Pannonia, etc.

 

1.      Mark McClear’s presentation  

Mark first introduced the meeting goals of TCS First meeting, which decide three major goals

1) Determine 3-5 areas of ISA interest

2) Form sub-groups to study each area

3) Set meeting date, time for second TCS meeting, receive sub-group reports

In his presentation, Mark introduced the principals for topics selection, which were: Meaningful, Not redundant, and Doable. And the various inputs from ISA General Assembly, which included:

•      TCS should consider focus on quality

•      TCS should not develop their own standards

•      TCS should develop their own standards

•      TCS should consider endorsing other standards

•      ISA needs to be international, gain an international voice – could TCS help with PR for ISA?

•      Consider work coming from ISA SRA as basis for standards, also other sources (international)

•      TCS should collaborate with other global standards bodies

(Quoted from Mark’s presentation)

 

The feedback from TCS members were:

Some inputs were obviously contradictory. Remarks on “the task of TCS”:

a.       “Promoting mutual understanding of various spec.”

b.      “Remove ‘encouraging energy saving’, which is the task of ISA not for TCS”

c.       “Zhaga is an open system”and “How to cooperate with Zhaga?”,

d.      “Legal issue, will it compete with other organization?”

e.       “Should provide harmonized and unbiased view.”

f.        “Should publish white paper instead of standards.”

 

Other Remarks:

a. “In order to join TCS, should his company be a member of ISA?”

b. “Chairman should be recyclable.”

c. “need to define the role of vice chairman.”

2.      Ten presentations were made following TCS1 agenda:

 

   1)     “Assembly methods for LED components and modules”, by Xiang Zhou. Mr. Zhou mainly discussed the impact and meaningfulness of module interface, the global standards situation, scope and content, and the partnership potential, and recommended setting up working groups, establishing measurement methods for LED modules and calling for standard proposals.  

 

Remarks:

“which components should be put in the standards”

“conflicting standards with Zhaga”,

“there could be two solutions to the standardization problem”

2)     “Terms and Definition for Plant growth”, by Lixia Zhao. Dr. Zhao pointed out that it was important to regulate the terms and definition of LED lighting in the aspect of agriculture application, and the proposed document would firstly define the terms and definition of LED lighting and control system for plant growth, to lay a foundation for the production, testing method, product quality standardization of the LED lighting for plant growth.

 

Remarks:

“How to define ‘good plant’?”

“there were electronic copy of definition of LED related terms by CIE on the web.”

3)     “OLED lighting, start with Communication”, by Manabu Tsumura. Dr. Tsumura believed the OLED would be made broadly available for premium lighting, the photo voltaic technology could work for OLED development, and 5 colors of OLED panels had been made commercially available. There were two streams of OLED lighting standardization: Standardization of light measurement and Standardization of Lamp and Lighting apparatus.   

 

Remarks:

Helea Hu “Our company already working on OLED standards along with CSA”

Mark McClear “two companies may work together on OLED standards”

4)      “Photo- biological safety”, by HuaiyuGu from CSA.

5)    “Shortening reliability testing time”, by Guoqiao Tao on behalf of Piet Derks, the main content included reliability, failure and lifetime, reliability, test duration and sample size, SSL elements & failure modes, and key component testing with higher acceleration factors.

6)   “Harmonize the international standards”, by Jiann Liu from Semileds. Dr. Liu emphasized that the cost was what the customers care, we needed SSL to save energy, and raised the question that does standard help to reduce cost or move market forward? There were many standards for applications and safety has high priority. Dr. Liu suggested setting up a survey on does standard help to reduce cost.

7)  “LED operation lighting”, Guangzhou Lu. Mr. Lu pointed out that considering that the LED was a kind of point-source light, it was necessary that we built a standard in order to avoid any injury that may caused to patients’ and doctors’ eyesight. A standard regarding to the color temperature and illumination intensity needs to be built in order to carry out successful surgeries. Due to the inconvenience of LED light replacement, the standard regarding emergency supply needed to be established in order to ensure the safeness of surgery.

8)   “Entry level specification for SSL applications”, Xiaoling Yan.

Professor Yan stressed that Transition to energy efficient LED would be much faster, and there were 2 phases for LED based innovations:

 

Phase 1:

Apply state of the art energy efficient lighting PRODUCTS to replace existing light sources (current EU EcoDesign Regulations)

Phase 2:

Apply efficient and intelligent lighting technology in well designed lighting SYSTEMS (new EU Lighting System Legislation)

 

9)  “Recycling and green design of SSL fixtures.” by Manabu Tsumura. Dr. Tsumura believed that we should apply thermoplastics as a heat sink material in terms of total energy saving and recycling. White parts are difficult for material recycling because of ‘resin burns’ and ‘foreign matter’. PET would be suitable for recycling compared with PA on terms of mold ability.

10) “Term and interface for factory to factory communications”, by APT. Mr. Sun from APT discussed that it was important to remove barriers to market adoption and to educate and improve the confidence in LED for consumers. He also suggested that a survey on the current standards on the terminology in LED industry should be conducted, and to collect the terminology and file or refer a standard.

 

3. Four voted directions to start with (in order of votes received):

1) “Entry level specification for SSL applications” (Volunteered participants: Philips, Cree, APT and TsingHua and TNO)

2) “Harmonize the international standards with LED applications” (Volunteered participants: Philips, Tsinghua University and Semileds

3) “Shortening reliability testing time” (Volunteered participants: Philips, Cree, APT, Semileds, CSA and TNO)

4) “Terms and Definition for Plant growth” (Volunteered participants: CSA and Semileds)

4.      Other resolutions

1) Mark would update the draft of Bylaws & Mission statement

2) The proposed TCS 3 meeting was Philadelphia during April 2013 light fair.
