Chinese LED manufacturer Honglitronic recently announced the company will release 300 million non-public offering shares to raise RMB 725 million (US $116 million). The purposes of this round of financing is mainly for the construction of SMD LED manufacturing facilities, acquiring 49% of Liangyou Hardware’s shares, and increasing bonds payable and circulating capital.

Lighting-level LED price declined 5-9% in 1Q14 as distribution channel inventory levels gradually returned to norm and manufacturers stock-up before Chinese May Day holidays, according to LEDinside, a research subsidiary of TrendForce. Backlight LED price dipped around 3-7%. Price declined steadily during 1Q14 compared to previous slack seasons.   

The University of Dundee is leading a European-wide research project to work on improving white LEDs that would be much more efficient than existing light bulbs. The project is being funded through a £7.2m grant from the European Union's FP7 programme. Currently, LED lights are only about 25% efficient and the researchers are hoping to improve that to 50-60%. Professor Edik Rafailov, NEWLED project leader based in the School of Engineering, Physics and Mathematics at Dundee, said: "Common lightbulbs have a pretty low efficiency rating and e...

IDEC Corp has utilized blue LED elements and yellow fluorescent materials to develop pseudo white LED modules. Under IDEC’s new method, an LED device can be packaged just by covering it with a gel-like silicon resin sheet containing a fluorescent material and heating it. Compared with a conventional method that packages an LED device by inpouring liquid resin, the new method can reduce the time used for packaging process to 1/9. With the conventional method, a "dam" is formed around an LED device on the substrate to keep the resin. Then, t...

Japanese companies from Tamura Corp and Koha Co Ltd have created a white LED using gallium oxide (β-type Ga2O3) and exhibited it at Lighting Japan 2013 from Jan 16 to 18, 2013. The LED consists of a blue LED chip made on a β-type Ga2O3 substrate by using GaN-based semiconductor and  a fluorescent material. Compared with a case where a common blue LED chip formed on a sapphire substrate is used, the new LED realizes a higher optical output. At the show, Tamura and Koha showcased two kinds of white LEDs that use 0.3 x 0.3mm and 2 x 2mm...

Scientists from University of Georgia have made breakthroughs on creating an LED that emits a warm white light using a single light emitting material, or phosphor, with a single emitting center for illumination. One of the researchers on the project, Zhengwei Pan, an associate professor in the department of physics in the UGA Franklin College of Arts and Sciences and in the College of Engineering, said in a posting on the UGA website, “Our material achieves a warm color temperature while at the same time giving highly accurate color rendition, which is somethin...

AIXTRON SE today announced a new MOCVD system order from existing customer Jilin University China. The contract is for one CCS reactor in a 3x2-inch wafer configuration, which will be dedicated to the growth of gallium nitride materials for UV and white LEDs. One of AIXTRON’s local support teams has installed and commissioned the new reactor in a state-of-the-art clean-room facility at Jilin University in Changchun, China. Dr. Zhang of the Jilin University, State Key Laboratory on Integrated Optoelectronics, comments, “We alre...

-Will mass produce on a new line at Kaga Toshiba Electronics – Toshiba Corporation (TOKYO: 6502) today announced that it will start mass production of white light-emitting diode (LED) on a production line that the company will construct in the 200mm wafer facility at Kaga Toshiba Electronics Corporation, a production base for discrete products in northern Japan. Mass production will start from October 2012. The energy efficiency and long life of white LED is winning wide-scale application in general purpose lighting, TV backlighting, etc. and significa...

According to price surveys by LEDinside, a research division of TrendForce, affected by dwindling Q1 inventory and Q2 rush orders, LED package price for the backlight application quotes has eased in Q2, with a decline of approximately 3%. On the LED lighting market, 5630 packages were pulled from use in backlight applications, to be used in lighting instead. The sudden volume increase resulted in price slashing for this quarter’s low to mid power LED packages, with an average decrease of around 10%. Q1’12 LED Price Review Due to relatively high Q...

According to Japan LED maker Nichia's website, Everlight Electronics Co., Ltd. ("Everlight") has filed patent nullity proceedings in Japan Patent Office against 19 patents held by Nichia Corporation ("Nichia"). Among such Nichia patents is the "YAG Patent", which is the Japanese Patent No. 2927279 ("279 Patent") and is directed to white LEDs by the combinations of blue LED and YAG phosphor. The JPO held on April 9, 2012, that the 279 Patent is valid over the Everlight's challenge. Nichia also sa...

Citizen Electronics Co Ltd developed a white LED whose maximum brightness is 17,675lm. This is the first time in the world that the brightness of a white LED has far exceeded 10,000lm, the company said. When the brightness of the white LED, "CLL-050 Series," is at its maximum, the input power and luminous efficiency are 183.9W and 96lm/W, respectively (when light is continuously emitted from the LED and the case temperature is 25°C). The new LED can replace a 300W mercury lamp, Citizen said. The LED has a general color rendering index...
