it can not only improve the brightness

Another epochmaking aspect of this R&D is the use of a proprietary aqueous solution method whereby a water-soluble silicon compound – propylene glycol-modified silane (PGMS)– is applied to achieve synthesis of a Si-containing oxide-based compound. Going forward, further usages of PGMS can be expected to accelerate the development of high-luminance and other new phosphors.

The technological development reported here is a direct outcome of joint R&D conducted in line with the cooperative agreement concluded between SMM and Tohoku University in October 2010. Further joint research will continue to go forward under this collaborative initiative.

The new bulb gives off almost 1160 lumens, and consumes 11.4 watts. It can be available in E26-base, and diffuses light like the incandescent light bulb. With the new bulb, it can not only improve the brightness, but also reduce power consumption.

Nuclear power shortage has driven up demand for LED lamps after the March 11 earthquake. Hitachi Appliances will diversify LED bulbs on brightness and light distribution to cater different demands from customers.

while all of hit new record quarterly highs

As a result, to increase greenhouse yields and decrease producers' energy costs, they will team up with Rutgers University, the University of Arizona, Michigan State University, and Orbital Technologies Corp. on the four-year project to improve and evaluate LED lighting for greenhouse use, according to Cary Mitchell, a professor of horticulture and project director for the grant. Total sales from January through September of 2010 hit NT$92.88 billion, up 35% YoY. Meanwhile, operating profit and net profit reached NT$5.67 billion and NT$6.8 billion respectively, with accumulated EPS of NT$3.05 increasing a remarkable 50% YoY. In 3Q10, The Company’s gross margin and operating margin reached 13.9% and 6.7%, up 0.9% and 0.4% QoQ, respectively. Lite-On’s net cash position held steady at NT$11.9 billion, after its recent cash dividend distribution of NT$5 billion. Non-operating items posted a net income of NT$508 million in3Q, with Perlos’ Q3 sales reaching €138 million, up 12% YoY. Perl...

LED lighting to reduce both power consumption

The new product is designed for use in bus & taxi stops, benches and walkway coverings and other public spaces. It is set to sell from July 20, exclusive to the Japanese market, targeting municipalities and led linear high bay light private companies. And the two manufacturers also propose its use for a wide range of applications across Japan. Its key features including:Firstly the shelter's solar power generating system can supply electricity for surrounding electrical needs, such as lighting for advertising displays, with excess power being sold to the power utility companies, thus helping to meet expected power shortages in Japan during the summer. Secondly, LED lighting to reduce both power consumption and CO2 emissions at night. Moreover, the shelter can play as emergency power supplier in the event of a disaster, as it has an independent power outlet that could be used to charge mobile phones or other vital electronics. During the several years, LED lights have gradua...

although some of the monster screens had relatively narrow viewing angles

Spark new tunnel light series includes 50w, 75w, 100w, 125w, 150w, 175w, 200w, which could meet different project requirements. From the exhibition we know Spark new LED tunnel light will be more and more popular, and illluminate more and more tunnels all around the world. Consumer Reports didn't render a verdict after just a quick look, but noted that Sharp "has definitely taken the lead in larger TV screen sizes." It cited the 60-, 70- and 80-inch sets from the past, saying they had typically done well in TV ratings, although some of the monster screens had relatively narrow viewing angles. Consumer Reports pointed out a question that "not everyone has the room -- or room in the budget -- for a 90-inch set." So, when rolling out the world's biggest TV (in its class, anyway), why bother with subtlety and understatement, right?Sharp Electronics of America President John Herrington said it "offers size, picture quality and smart functionality unlike anyt...
