We are IR LED manufacturer from China.
You can see some weak red bright when the 850nm IR LED is working, But you can see nothing when the 940nm IR LED is working. Unless you watch it through some device(like phone's camera), which will show some purple or white color light.

Catalog of IR LED.
All of our product are meet with Reach, CE, RoSH, SGS, EN62471 standards.
IR LED(Infrared LED), normally, which is 850nm IR LED and 940nm IR LED.
IR LED widely used for those "night-vision" cameras, IP camera, remote controls, Touch screen, intelligent monitoring, webcam, hunting camera, CCTV cameras, surveillance cameras and security system. For instance, 940mn Through-hole IR LED did a great job in night-vision. 850mn SMD IR LED did a great job in infrared touch screen.
We use the best raw material, like Taiwan's Epistar chip, Tyntek chip, optocech chip and 99.99% gold wire for your best prouct, which is make our product have a fabulous performance. Looking forward to cooperate with you.
Prospects for China's wind power industry are still on the horizon
"China's transition to renewable energy is an unavoidable path," said Du Guangping, a senior member of the China Wind Energy Committee under the China Renewable Energy Association. Recently speaking in Beijing, he emphasized that while the future of China’s wind power industry remains promising, it is crucial to master core technologies and enhance overall development capabilities. Otherwise, the industry could face greater challenges down the line.
According to the "Power Industry Operation Profile for January-July 2013" released by the China Electricity Council, the growth rate of domestic wind power generation has declined for three consecutive years. Can the wind power sector "heat up"? How can the industry overcome its current obstacles? At a themed salon titled “Analysis of Wind Power Industry Development at Home and Abroad and Prospects for China’s Wind Power,†sponsored by the All-China New Energy Chamber of Commerce, Du Guangping addressed these issues.
In 2012, global wind power capacity reached a record high of 44.95 million kilowatts, with offshore wind power capacity more than doubling. As of June 30, 2013, China had added 5.5 million kilowatts of new wind power capacity, bringing the total installed capacity to 80.82 million kilowatts—making it a third major power source alongside coal and hydro.
Global wind power is expected to grow significantly, with its economic value projected to rise from 57.7 billion euros in 2012 to 85.4 billion euros by 2017.
While onshore wind power growth has slowed, offshore wind power is gaining momentum. According to Du Guangping, global offshore wind equipment markets are expected to grow at an average annual rate of 30% in the coming years. By 2015, global offshore wind farm capacity is expected to reach 5,761 megawatts.
China’s first offshore wind farm demonstration project, the 102 MW Shanghai Donghai Bridge Wind Farm, has been successfully operating since its launch. In the first three quarters of this year alone, the project generated 194 million kWh of electricity.
Du Guangping believes that to achieve the goal of having non-fossil energy account for 15% of primary energy consumption by 2020, China’s wind power industry will continue to develop steadily over the next five years.
However, he also pointed out that wind power grid integration technology, management standards, and the overall competitiveness of wind power equipment need improvement. Additionally, the electricity pricing policy and subsidy mechanisms for wind power must be further refined to support sustainable development.
