As far as lighting is concerned, the brightness of people's demand for lighting is constant. In the future, the brightness of lighting can be automatically changed according to the change of sunlight. Through the sensor, people can not even feel the existence of the lamp. When people go home at night, the lights are on. When the brightness is enough during the day, the lights are automatically turned off, and when the brightness is insufficient, the lights can consciously make up enough light. These scenarios need to be implemented through intelligent control, and the key to control lies in the chip.
At present, lighting technology is undergoing an unprecedented transformation, from bulbs and fluorescent lamps to LEDs. The new white LEDs consume only one-tenth the energy of ordinary light bulbs, so white LEDs can save a lot of energy both in materials and in use. In the near future, tri-color LEDs may replace the combination of blue LEDs and phosphorous phosphors for high-brightness illumination and enable dynamic control of color composition.
It is understood that lighting accounts for 20%-30% of the global electricity consumption. Therefore, some insiders assert that the next three years will be the "golden age" for the development of the LED industry, and will have a market capacity of hundreds of billions in the next five to ten years. And with the merger and integration, there will be a “Giant†enterprise.
How to “work hard†in the current LED market, some successful people said that they must first visit the market, understand the situation, segment channels, innovate products, gain trust, and thus promote the market. In the energy-saving service industry, there are nearly 3,120 energy-saving service companies registered in the country with nearly five batches of lighting-related service companies. Whether they can master the "core" technology and whether they can occupy the market will be the key to a brighter future.

High performance
Application: flow meter measurement
There are many kinds of USF used in closed pipeline according to the measuring principle, and the most commonly used are propagation time method and Doppler method. Among them, time difference ultrasonic flowmeter is used to measure fluid flow by the principle that the time difference of sound wave propagating downstream and countercurrent is proportional to the velocity of fluid flow. It is widely used in raw water measurement of rivers, rivers and reservoirs, process flow detection of petrochemical products, water consumption measurement of production process and other fields. According to practical application, time-difference ultrasonic flowmeter can be divided into portable time-difference ultrasonic flowmeter, fixed time-difference ultrasonic flowmeter and time-difference gas ultrasonic flowmeter.
Ultrasonic flow-meters use at least two transducers aligned so that ultrasonic pulses travel across the flow of liquid or gas in a pipe at a known angle to the flow.
