"Twelfth Five-Year" Energy Saving and Environmental Protection Plan: LED output value reached 450 billion in 2015
Recently, the State Council issued a notice on the “Twelfth Five-Year Plan for Energy-saving and Environmental Protection Industry Development”. The "Plan" delineates eight major projects in the energy conservation and environmental protection field, such as the industrialization of major energy-saving technologies and equipment, the construction of a seawater desalination industrial base, and the cultivation of energy conservation and environmental protection services
Ministry of Industry and Information Technology releases "China's roadmap for gradually reducing mercury content in fluorescent lamps"
According to the “12th Five-Year Plan for Industrial Clean Production”, during the “12th Five-Year Plan” period, mercury pollution reduction projects will be implemented with the focus on low-mercury fluorescent lamps and the use of mercury-fixing technologies in production. The introduction of a series of policy measures provides a good policy environment for mercury reduction in fluorescent lamps. my country has mastered the production process of mercury solids, and high-performance low-mercury amalgam and other supporting materials have also been domestically produced, which can effectively reduce the mercury content of fluorescent lamps and reduce mercury emissions during production and recycling.

LED Device Naming
It is possible that more than one LED with the same color and function will be required for given platform, differing only with an ordinal number. In this case it is preferable to just concatenate the predefined LED_FUNCTION_* name with required “-N” suffix in the driver. fwnode based drivers can use function-enumerator property for that and then the concatenation will be handled automatically by the LED core upon LED class device registration.
LED handling under Linux
In its simplest form, the LED class just allows control of LEDs from userspace. LEDs appear in /sys/class/leds/. The maximum brightness of the LED is defined in max_brightness file. The brightness file will set the brightness of the LED (taking a value 0-max_brightness). Most LEDs don’t have hardware brightness support so will just be turned on for non-zero brightness settings.

Black technology: using single-layer semiconductor to make ultra-thin LEDs
Therefore, the most difficult problem in improving the luminous efficiency of LEDs is how to make free electrons and holes contact more efficiently. Especially when the size of the semiconductor is only a single layer thick, not many materials can be used, which makes the difficulty even more. For single-layer semiconductors, researchers use transition-metal dichalcogenides (Transition-metal dichalcogenides, TMDCs for short) to make single-layer semiconductors. This material has semiconductor properties similar to graphene and is considered to be an important photoelectric material for the next generation.
