U.S.A. national semiconductor announces the WEBENCH Designer series design tool of this company increases WEBENCH LED Architect newly, a set of homework is extremely fast, with the characteristic brand-new design tool of display system of figure chart.
This is first tools which design LED systematic framework, can offer for exporting the lighting system up to 100,000 lumen and design supporting. Pass this set of tools, both designing expert of the circuit and elementary designer can easily instant comparative the intersection of LED and efficiency, drive current and the intersection of heat energy and the intersection of person who compensate and terms of demand, and find out the optimization solution during the every minute and second among the efficiency, scheme magnitude and cost.
In addition, this set of tools can also analyze the characteristic of different chips, include 12 350 LEDs, 30 heat sinks, 35 sections of LED driving devices which big factories introduce newly... Read more
According to the comprehensive working scheme of energy-conserving emission reduction that the State Council releases, the committee of development and reform popularizes 150 million products of lighting LED through the financial subsidy way. According to the estimation by related departments, after this plan is all implemented, 29 billion kilowatt-hour that can economize on electricity totally in one year in the whole country, discharge little 29 million tons of carbon dioxides, 290,000 tons of sulfur dioxide.
The result is obvious to all, but LED electricity-saving lamp price is too expensive has been a problem that can’t be solved all the time at present. Room lighting involves the huge numbers of families, the market of room lighting is bigger than that of the market of outdoor lighting after LED illumination really popularizes, on playing up in room lighting especially atmosphere that LED is used in, there is incomparable advantage of any other light sources in the...

A few days ago, green, Jiangxi of China, light semi-conductive lighting the intersection of industry and cooperation move forward, can open in Nanchang. Sign 15 collaborative projects at the meeting, attract the investment amount of 15,924,600,000 yuan. 70% of the project selection contracting on the same day settles in Nanchang.
It is reported the signing project obvious in coastal trend that shift to the intersection of Mainland and industry. A lot of LED enterprises come from coast lands such as Hong Kong, Shenzhen, Dongguan, Taiwan,etc.. Unless the same day project signing 15 pieces altogether, unless 11 Nanchangs among them, sign Ji’an city 3 pieces,should spring sign city by every one.
In recent years, it is fast growing that Jiangxi Province lights for representatives’ green lighting industry with the semiconductor, from January to July, the green lighting industry of the whole province realizes and manages the business income of 2,280 million yuan mainly ... Read more
Stranded in the economic depression of this country, Japanese Government has announced total value as 920 billion Japanese yen (about 10,800 million dollars) ahead of time Singapore economic to be amazing for scheme. It is reported, this stimulates financing budget of the scheme to come from government’s for 2009-10 fiscal years preparing funds, this scheme plans to refer to the Congress to sanction on September 10, and carry out at the end of September.
Causing the factory to adjourn to in order to prevent Japanese yen from appreciating causes abroad ” The vacuum of industry ” ,The government determines, if confirm that sets up luminescent diode (LED) in China And production bases correlated to environmental protection such as lithium cell,etc., the government will set up and replenish the system, so as to promote enterprises to invest in China.
Japan, to LED lamps and lanterns and numerous issue of enterprise’s subsidy policy, it is basically by p... Read more
Global and leading German lamps and lanterns manufacturers Norka are chosen ultra-performance LexanDMX polycarbonate (PC) of the innovative plastics of Scharber’s foundation Copolymer resin is used in its Luzern38 luminescent diode (LED) New production line of the modulator tube. LexanDMX resin can be stood and looked like domestic animal of livestock’s canopy, zoo beast’s cage and abominable and environment that the ammonia content is high of housing in the field in pens of other animals, make Norka create the special lighting products that specially face this small all markets.
Different from the traditional PC material, the new LexanDMX resin has outstanding diaphaneity, resists and atomizes the characteristic and resists completely the anaclasis reduce ability, even it is not easy to become fragile to exposed to the ammonia for a long time either, thus lengthen the life-span of the modulator tube, reduce energy consumption.
In the past, Norka used incan... Read more
ADI introduces the driver in a poor light of ADP8870 white light LED charge pump recently, it can make the power consumption of the battery-driven handheld apparatus reduce by up to 45%, and does not influence revealing quality. ADP8870 collects three key functions in an organic whole: Programmable LED charge pump driver in a poor light; Used for the phototransistor of autocontrol LED luminance inputting; And is used for managing PWM (puls e-width modulation) of the output current proportion Input. So, it can change current strength automatically according to environmental illumination intensity and white light composition of the display image, thus reduce the power consumption by a wide margin. ADP8870 Yes this function of automatic performance, do not need to make use of processor to control the phototransistor, therefore can further reduce power requirement and simplify and design portably and in a poor light.
The product line director Dan Swan of product division of the ... Read more
Recently, the national laboratory (ORNL) of mountain range of American oak Researcher succeed in already for one kind graphite foam,use for not solving the problem that because the high-temperature environment of operation of high light LED and the life-span shortens, and authorize this graphite foam technology to the company appearing through independence of this laboratory exclusively - -LED North America.
ORNL shows, operate the temperature of LED and lower ten degrees and can let its life time lengthen one time; Such every local government can change the Off-The-Shelf mercury street lamp into a LED lamp, in order to save the electric rate up to several million dollars, does not need to bear the LED lamp and pass the unripe risk of thermal technology again.
It is reported, the similar foamed plastic of graphite foam, light and porous, the density is 25%, this make the very apt to make air-cooling fin into material. In the future, LED North America plans to utilize graph... Read more
The lighting system on the car not only lets the driver understand the state of the car actually, having offered it in the course of safety drive even more, the condition that there must be. And new monobasic the intersection of light source and LED, for a lot of consumers is not at all non- strange, has already further expanded and applied to the car, and in the face of different demands for efficiency according to each application, choose the suitable LED products. Basically, because LED and traditional light source are except except appearance difference on, only appearing has a very great difference to output with efficiency too, so, should apply LED to the auto bulb improving, including optics design and scattered thermal design,etc., different from the design concepts of the traditional car lamps and lanterns. Car and LED succeed in carrying on integration, becomes all brand-new design concepts of car making.
The light source of the car is occupying very important positio... Read more
Today, the reporter learns from the government of Jiangmen city, in ” the first overseas Chinese hometown ” Jiangmen of Guangdong, lights (LED) with the semiconductor in recent years Fast growing for representatives’ green light source industry, the average annual speedup has exceeded 30% in the past three years, 2009 Jiangmen green ( Semiconductor) The light source industry realizes 9,500 million yuan of output value, account for the whole province LED output value (38 billion yuan) 1/4.2010 annual for July January for green (semiconductor) The total industrial output value of light source is 6,128 million yuan, increase by 26.82% compared with the same period of last year, the growth rate is much higher than the industrial growth level in the whole city.
LED, as a new kind of light sources, because of having characteristics such as low temperature, electric-saving, long life, having no secondary pollution,etc., a succession of green today in vogue of conce... Read more
