news digest ♦ LEDs and LM-79 lighting product testing at the same time.
In the future, Lextar will be able to use its own laboratory for product testing, which will simplify testing procedures, decrease time and lower costs, as well as speed up the company’s ability to capture LED lighting business opportunities across the world.
In addition, Lextar’s 3014 and 5630 LED packages have completed 6,000 hours of LM-80 testing over a course of nearly 9 months and are able to remain a high standard luminous output when subjected to temperatures at 550C and 850C, showing that the products have enhanced their lifespan reliability.
Lextar says its 3014 and 5630 packages have many advantages such as high degree of stability and quality, and can be used in bulbs, tubes, down lights, panel lights, advertising light boxes as well as in many other applications, making them the most popular of LED products within the company.
Lextar’s CoB product series is also the process of LM-80 testing, which is expected to be accredited as of next year.
DAS system eliminates waste gases in LED industry
DAS Environmental Expert GmbH has developed a new product solution for environmentally friendly cleaning of process gases such as ammonia and hydrogen, which are used during LED manufacturing
DAS Environmental Expert GmbH has developed the “LARCH” system for the environmentally friendly disposal of reactive waste gases released during the production of LED wafers.
As the statutory provisions on waste water and waste gas disposal will be tightened in Taiwan from 2013 onwards, Taiwanese companies will soon have to start looking around for new solutions.
Taking into account that our world is becoming more ecologically aware, engineers at DAS have recognised that it is necessary to eradicate waste process gases in an eco-friendly manner.
“With LARCH we are specifically reacting to requirements from LED makers. The LED industry is known to be a growth market and in our discussions with customers we have become aware of the demands made on modern disposal technologies,” says Guy Davies, Director Business Unit GasTreatment.
“We have given a great deal of thought to this and the LARCH system is the result. It has already generated a lot of interest: enquiries from some potential customers have already come in,” adds Davies.
Industry analysts predict sustained growth in demand in the LED market. After LED backlighting for the small LC displays of mobile phones and the LC displays of larger screens in the television market, the next potential growth market is the lighting industry. Sales of LEDs in this market in 2012 are almost $3.5 billion, nearly doubling since 2010. Yole Développement is expecting a growth of more than $7 billion in 2014 and believes that the total market for LEDs should peak at $17.7 billion.
A mass market on this scale for LEDs also means increasing emissions. In the manufacture of products based on innovative LED technology, ammonia and hydrogen are used in large quantities as process gases.
In the new LARCH system, the initial thermal dissociation of ammonia is achieved by reaction heat. Hydrogen is then ignited and burnt off by electrical heating elements. The reaction heat is transferred to a downstream heat exchanger. This is an elegant solution for the disposal of the large quantities of process gases generated in LED production.
