Guizhou Provincial Economic and Information Committee will carry out research activities on stone and other building materials

The content of this survey mainly includes three aspects. The first is to investigate the development status of Guizhou building materials industry. Focus on the production scale, output value, profit, number of employees and the use of "three wastes" resources of cement, wall materials, concrete (mortar) and products, chemical building materials, construction and decorative stone materials. The second is to collect and collate relevant technical standards and industrial policies of the existing building materials industry. Focus on collecting technical standards and industrial orientations for bulk building materials such as cement, wall materials, concrete (mortar) and products, chemical building materials, construction and decorative stone. The third is to investigate the development of the “Twelfth Five-Year Plan” of the building materials industry in each city and state. This special investigation is a comprehensive survey of the overall situation of the development of building materials industry in Guizhou. The aim is to further implement the strategy of strengthening the province and vigorously develop the industry's top ten industries.

5050 SMD IR LED

5050 SMD IR LED supplier from China.

For 5050 IR LED, we supply variety of products, there are 5050 SMD LED with 6 pin and one chip infrared 5050 SMD, 5050 SMD LED with 6 pin and two chip infrared 5050 SMD,5050 SMD LED with 6 pin and three chip infrared 5050SMD, 5050 IR LED with 2 pins and one chip, 5050 IR LED with 2 pins and multi chip etc.

In addition, we also add the lens on the top of SMD LED, which can make the SMD LED have an angle like those Thought-hole LED.
For example: 5050 SMD 850nm IR LED with 30 degrees, 5050 SMD 850nm IR LED with 60 degrees, 5050 SMD 850nm IR LED with 90 degrees, 5050 SMD 940nm IR LED with 30 degrees, 5050 SMD 940nm IR LED with 60 degrees, 5050 SMD 940nm IR LED with 90 degrees, etc.
We also can customize the mold of ledns as you needed angle.

We produce and sell 5050 SMD IR LED, which is with the wavelength from 680nm-1550nm. In this category, we mainly introduce the two kinds of wavelengths: 940nm IR LED and 850nm IR LED. These two wavelengths are the most commonly used wavelengths in infrared monitoring. They all can be used to monitor products.
Then what is the difference between 940nm and 850nm?
940nm infrared LEDs are totally invisible to the naked eye, which means you can't see whether the 940nm working or not. Unless you watch it through some device(like phone's camera), which will show some purple or white color light.
The 850nm infrared LEDs have a very slight reddish when it's working, which means you can see if the 850nm LED is working.
Under the same power, radiation intensity of 850nm will be higher than the 940nm. Of course, 940nm also has its own unique advantages. It is the naked eye that is indistinguishable from work or from work, therefore, its application has been widely used in many special markets in the modern era.
We supply the 5050 940nm SMD IR LED and 5050 850nm SMD IR LED products with difference power, such as: 0.1W 940nm, 0.2w 940nm, 0.3w 940nm, 0.4w 940nm, 0.5W 940nm, 0.6w 940nm, 0.8W 940nm, 1w 940nm, 3W 940nm, 0.1W 850nm, 0.2w 850nm, 0.3w 850nm, 0.4w 850nm, 0.5W 850nm, 0.6w 850nm, 0.8W 850nm, 1w 850nm, 3W 850nm and so on.
