LED industry will be able to overcome the oversupply glut over the last few years in 2014, as it hops onto lighting’s growing trend, according to estimations by Veeco. Epistar Chairman B.J. Lee projected earlier the LED supply and demand situation will gradually ease in 2014, and LED manufacturers are also optimistic about lighting developments in 2014. Large MOCVD manufacturers such as Veeco are also optimistic about a new generation of MOCVD equipment demands spurred by LED lighting growth.

In recent years, the LED light source has dramatically changed the lighting industry, adding numerous possibilities in lighting and it is expected both by the industry and the household users to completely replace the traditional light source as a brand new light solution in the near future.

Observance of an International Year of Light in 2015 will help raise awareness of the important role of photonics in solving challenges in healthcare, communications, food supply, and other important issues for people everywhere, say leaders of SPIE, the international society for optics and photonics. SPIE is among scientific organizations around the world that have championed proclamation by the United Nations of the observance, and whose members are planning outreach activities and celebrations.

A standard way to configure the backlight is to use two discrete devices: a 100 V MOSFET in a DPAK package and a 100 V Schottky diode, also in a DPAK package. High leakage current of Schottky diode can be a problem in LED backlight units, especially at higher temperatures. Some customers have experienced leakage failure issue of Schottky diode during mass production. One way to improve the leakage failure is to increase the Schottky diode’s voltage rating from 100 V to 120 V, but leakage current can still be an issue when the system temperature is high.

NEMA’s Electroindustry Business Conditions Index (EBCI) for current conditions in North America slipped below the 50-point level typically associated with expansion in January for the first time since October 2012. The index declined for the third straight month, falling to 40.6 from 52.8 in December. The share of respondents that reported conditions improved in January declined to 12.5 percent from 16.7 percent in December, while the share reporting conditions deteriorated increased to 31.3 percent from 11.1 percent. Just over 56 percent of respondents indicated that conditions were unchanged from December to January.

Lumex announces the global launch of its TitanBrite High-Voltage, Low-Current LED, the newest addition to the TitanBrite family of high-power LEDs. The TitanBrite High-Voltage, Low-Current LED can run at a higher voltage with a lower current than alternative technologies (such as a traditional10W LED) while providing up to 45% brighter light output and superior light distribution. This allows for up to 20% cost and 50% real estate savings for applications requiring low current, but high light output. Though high-voltage, low-current LEDs provide key performance benefits for applications that use LED drivers that offer higher voltages to drive a high-power LED, few design engineers are aware that these technologies are available and can produce the comparable if not brighter light output.

LED lightings represent a green light source which offers energy saving and long lifespan advantages. Nowadays, it has been popularized in our daily life. It has continuously replaced lighting devices such as incandescent lighting and fluorescent lighting. Either in household life or working environment, lighting fixtures are closely linked to you and us. Today’s LED lighting products can be problematic with blinding light, glare, high light loss and insufficient light source. Long-term usage can provoke uncomfort such as eyestrain.
