Lextar introduces the first high-efficiency photolithography LED light tube for clean rooms

Date Announced: 25 Oct 2010 Oct. 25 – Lextar Electronics Corporation reveals today a series of new lighting applications, including the world’s first* high-efficiency photolithography LED light tube for clean rooms, high-brightness LED light tubes of 2,600 lm, ultra light and bright LED bulbs of 1,000 lm, and CCT adjustable flat panel light. The products will debut at the 2010 Hong Kong International Lighting Fair (Autumn Edition) held at the Hong Kong Convention and Exhibition Center from Oct. 27 to 30. These innovative products will demonstrate the diversity of LED products and the technical strength of Lextar. Lextar will display four main series of products: LED light tubes, LED bulbs/downlights, LED panel lights and COB (Chip-on-Board) light engines.LED Light Tube Series:In LED light tubes, Lextar introduces the world’s first* high-efficiency photolithography LED light tube for clean rooms. The novel product uses a technology that combines a special LED and a specially-made light tube lens with cut-off filters. It can filter wavelengths of less than 500 nm and its efficiency is double that of similar tubes made with amber LED which are currently on the market. It is the ideal lighting product for plants and clean rooms. As plants require long hours of lighting, using LED light tubes can save 50% of energy compared to traditional light tubes. For 24 hours of lighting a day, 100 LED light tubes can save around USD 200 a month. It has a life-time of 40,000 hours, which is 7 to 10 times longer than that of traditional tubes. Another product, a high-brightness high-efficiency LED light tube of 2,600 lm, boasts the efficiency of 100 lm/W, and its high-brightness design extends its application to business environments with high ceilings, such as halls or factories. In addition, Lextar is introducing an ultra light plastic LED tube of 175 g, which is a breakthrough in LED lighting technology by the Lextar R&D team. LED Bulb/Downlight Series:In the bulb series, Lextar introduces an ultra light and bright LED bulb of 1,000 lm to replace the traditional 100 W incandescent bulb. Its power consumption of 12W saves up to 88% of energy compared to traditional bulbs. Its non-metallic heat sink reduces the weight to below 140 g, which leads to easier mounting. It establishes a new generation of specifications for LED bulbs in the industry. Lextar is also exhibiting a number of adjustable LED light sources, including a slim designed dimmable downlight module of a 2-cm thickness with a remote control, and a 4.5 W dimmable bulb, which demonstrate Lextar’s full range of technology development in LED lighting applications. LED Flat Panel Light Series: With years of R&D technology in TFT-LCD backlights, Lextar extends the LED backlight technology to lighting products. Lextar is exhibiting a 60 x 60cm CCT adjustable LED flat panel light with a remote control which offers color temperatures ranging from warm white to cool white. The user can adjust the color temperature according to the occasion, time and mood to create difference ambiences. LED panel lights emit a soft light produced by a secondary source. It creates a stable and soothing lighting effect which is suitable for offices, hospitals, schools and shopping centers.COB Light Engine Series:In addition to lighting applications, Lextar’s COB (Chip-on-Board) light engine is a core component in lighting products. Lextar will showcase its mega high brightness 70W COB of 8,000 lm in the exhibition. In addition, COB light engine series of 4 W, 6 W, 10 W, 70 W and 100 W will be on display in the exhibition, and product application ranges from low-power bulbs to high-power bay lights, street lights, architectural light and more. The features include high stability, long lifespan and multiple applications. Lextar Chairman and President, Dr. David Su, states that the new products revealed at the Hong Kong International Light Fair are comparable to products from international brands in specifications and applications. The innovative products clearly demonstrate Lextar’s all-round technology development in the lighting domain. The Lextar lighting R&D team is aggressively developing new technologies in LED lighting sources and light modules. Lextar also offers customized solutions to different markets and clients, including OEM and ODM services for international brands, as well as provides total solutions for light modules.*Based on available market research information as of Oct 25, 2010.About Lextar ElectronicsLextar Electronics Corporation (TAIEX 3698), founded on May 23, 2008, is part of BenQ Group.
