Signify's predecessor was Philips' lighting company, which produces Hue brand smart lights. Today, the company announced the launch of a series of new data transmission Li-Fi lights called Truelifi. This visible light source unit can use light waves to transmit data to devices such as laptop computers at speeds up to 150Mbps instead of the traditional 4G or Wi-Fi radio signals.
The Truelifi series includes communication lights and transceivers that can be retrofitted into existing home lighting systems. If you think the speed is not fast enough, you can connect two fixed points wirelessly, and the data rate can be superimposed to 250Mbps.
Signify's original goal was to provide professional markets such as office buildings and hospitals with long-term lighting, rather than homes, but the maturity of technology allowed it to reach a wider audience.
Li-Fi technology has been around for many years-but so far it has not been widely adopted. Most Internet-connected devices (such as laptops and smartphones) require an external adapter to receive data via Li-Fi. Due to visible light communication, the signal is blocked when the receiver is covered and blocked. And Signify said that its Truelifi products need to occupy a USB interface to receive Li-Fi signals.
However, when appropriate, Li-Fi uses light instead of radio signals to transmit data, which has its advantages. For example, it can be used in areas where there may be a lot of radio frequency interference, or in hospitals and other places where RF signals may interfere with sensitive machines. Although making shadows can easily block Li-Fi signals, this shortcoming can in turn enable precise directional communication, because users can better control the location of network propagation by blocking visible light.
Piston Seals and Rod Seals are important seals used in mechanical equipment. Their main function is to prevent liquid and gas leaks and ensure the normal operation of mechanical equipment. Piston seals and rod seals are usually used in hydraulic and Pressure system, such as hydraulic cylinders and Pneumatic cylinder. The quality and performance of these seals directly affect the efficiency and lifespan of mechanical equipment.
The classification of piston seals and rod seals is mainly based on their material and design structure. According to the different materials, they can be divided into rubber seals, polyurethane seals, polytetrafluoroethylene seals, metal seals, etc. According to the different design structures, they can be divided into unidirectional seals, bidirectional seals, rotary seals, etc.
Rubber seals are a common type of seal, and their main material is rubber. Rubber seals have good sealing performance and wear resistance, and are suitable for medium and low pressure hydraulic systems and Pressure system. Polyurethane sealing element is a high-performance sealing element, and its main material is polyurethane. Polyurethane seals have high wear resistance, high temperature performance and high pressure performance, and are suitable for high-pressure hydraulic systems and Pressure system. PTFE sealing element is a corrosion-resistant sealing element, and its main material is PTFE. PTFE seals have excellent corrosion resistance and high temperature resistance, making them suitable for fields such as chemical and food processing. Metal seals are a type of high-temperature and high-pressure seal, mainly made of metal. Metal seals have high temperature and high pressure performance and corrosion resistance, and are suitable for high temperature and high pressure hydraulic systems and Pressure system.
Unidirectional seals and bidirectional seals are classified based on different sealing directions. A unidirectional seal can only prevent the leakage of liquid or gas from one direction, while a bidirectional seal can prevent the leakage of liquid or gas from both directions. Rotating seal is a type of seal that can rotate and is mainly used for sealing rotating shafts. Rotary seals are divided into unidirectional rotary seals and bidirectional rotary seals.
