Rambus, a technology licensing company, actively entered the LED application industry in 2010. Its patented MicroLens technology entered the LED backlighting and lighting market. Rambus said that MicroLens will achieve LED backlighting, LED cost reduction and material cost enhancement in LED backlighting process. The benefits of the force, such as 46-inch LED TV will achieve a 30% savings in backlight costs, and the LED TV backlight module with single-sided illumination will be expected to be mass-produced in 2011, when the number of LEDs for 40-inch LED TV will be used. It can be reduced from 240 to 142.
Rambus said that the global lighting device market is about 800 billion US dollars. In 2010, the LED lighting penetration rate is only about 4%. According to estimates, the top 20% of the market customers are early adopters, and then will enter the price and product performance. Considering the rapid development period, the market share is about 30%, and its output value is about 240 billion US dollars. In order to develop into this huge market, the price of LED lighting that consumers can accept must be reduced to 20% of the traditional lighting. Corporate customers must be able to recover their electricity bills within two years of their investment, and further need to achieve the goal of recycling within one year.
After Rambus acquired the MicroLens lighting and optoelectronics patent and R&D team from Maolin for US$26 million, the technology integration has been completed. Rambus and the global lighting manufacturer GE have signed a licensing agreement to focus on the architectural and commercial lighting panels. LED lighting systems will enter the global market in the future. Rambus said that because of the MicroLens technology, the angle of divergence of the light source can be controlled to be applied to curved lighting products. At present, prototypes of LED lighting products such as suspension and double-sided chandeliers have been completed, and mass production is expected in 2011. Office area lighting will be the largest application market for LED lighting in the future.
In the LED TV market, Rambus said that the penetration rate in 2010 is about 20%. In order to continue to grow to a market penetration rate of 50%, under the market expansion, the cost continues to decrease, and its price must be lower than the CCFL price difference. Within 10%, Microlens' optical technology can achieve the focus of the light source, and the light distribution of the light guide plate is evenly dispersed, so that the optical design efficiency of the edge-lit LED TV is improved by 20~30%.
In addition, unlike traditional printing or laser processes, Microlens uses roll-on technology to reduce the thickness of the light guide to less than 0.3mm, while the material requirements for diffuser plates are also expected to decrease, driving material costs down, Rambus estimates, using The cost of a traditional 46-inch TV light guide is about $30, and Microlens can be reduced to $20, which is equivalent to a 30% cost savings.
According to Marc McConnaughey, vice president of Rambus Strategy Development, Marc McConnaughey said that 50% of LED TVs are larger than 40-inch models. In 2010, LED TV backlights are mostly designed with upper and lower sides, and will enter in 2011. The left and right sides emit light, and the LED TV backlight module will enter the one-side illumination to achieve the lowest cost. He predicted that the number of LEDs for 46-inch LED TVs will be about 240 in 2010, and will be reduced to 172 in 2011. By 2012, the number of LEDs will be reduced to 142, which is now available. The 55-inch LED TV model is expected to be mass-produced in the middle of 2011, and Rambus has already licensed the technology with a number of brand factories or backlight modules.
LED street lamp refers to the street lamp made with LED light source, which has the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response speed, high color rendering index, and is of great significance to urban lighting energy saving.
