Low Voltage Light Manufacturers Last...
LED light strips are often used to outline the contours of various buildings. According to the differences in the use of LED light strips and different requirements for light strips, there are two types of high-voltage LED light strips and low-voltage LED light strips. Light strip, low voltage LED light strip is also called DC light strip. The difference between high voltage light strip and low voltage light strip 1. The difference between high-voltage light strip and low voltage light manufacturer strip is mainly in terms of safety, installation, price, packaging and service life; 2. Safety: The 220V voltage used by the high-voltage LED strips is a dangerous voltage, and there are hidden safety hazards in some risk applications. Low-voltage LED strips work at a DC 12V operating voltage, which is a safe voltage and can be applied to various On this occasion, there is no danger to the human body; 3. Installation: The installation of high-voltage LED light bar is relatively simple. It can be directly driven by a high-voltage driver. Generally, the factory can be configured directly, and the 220V power supply can work normally. The installation of low-voltage LED flexible light strips requires a DC power supply in front of the light strips, which is relatively complicated during installation; 4. Price: If you look at the two types of lights alone, the price of LED strips is similar, but it ’s different from the overall cost, because high-voltage LED strips are equipped with high-voltage power supplies. Generally, one power supply can bring 30 ~ 50 meters LED flexible light bar, and, relatively speaking, the cost of high voltage is relatively low. Low-voltage LED light strips must be equipped with a DC power supply. Generally, the power of a 1-meter 60-bead 5050 light strip is approximately 12 ~ 14W, which means that each meter of light strip must be equipped with a DC power supply of about 15W. The cost will increase a lot, much higher than the high-voltage LED strip. Therefore, from the perspective of overall cost, the price of low-voltage LED lamps is higher than that of high-voltage LED lamps; 5. Packaging: The packaging of high-voltage LED strips and low-voltage LED strips are also very different. High-voltage LED flexible strips can generally be 50 ~ 100 meters / roll; low-voltage LED strips can generally be up to 5-10 meters / roll. ; DC power supply attenuation beyond 10 meters will be very strong; 6. Service life: The service life of the low-voltage LED strip is technically 50000-100000 hours, and the actual use can also reach 30,000-50000 hours. Because of the high voltage of high-voltage LED strips, the amount of heat generated per unit length is much more than that of low-voltage LED strips, which directly affects the life of high-voltage LED strips. Generally speaking, the high-voltage life is about 10,000 hours.

How To Use The Stone Polishing Machine
Speaking of stone polishing machine, I believe everyone is not sure what it is from, and this device will feel strange. So, what exactly is a stone polishing machine? In fact, the stone polishing machine is a kind of equipment that uses mechanical equipment to run quickly and "dry polishing, wet polishing" to achieve the polishing effect. Then, let the doctor Shishi Stone renovation Xiaobian to introduce to you the working principle of the stone polishing machine and the knowledge of influencing factors. Introduction to the working principle of stone polishing machine Particle grinding: When the abrasive particles are coarsely ground to finely ground and polished, the traces of abrasive grinding on the surface of the stone range from coarse to fine to no traces visible to the naked eye. The surface appears smooth, flat and delicate. When the depth reaches 110 At the micron level, the processed surface appears specular, shiny and bright in color. Physicochemical principles: There are two polishing processes, namely "dry polishing and wet polishing". The polishing stone is between "dry and wet" when the physical and chemical action of the stone product occurs. Dry polishing is the increase in the temperature of the stone surface to make moisture Evaporation leads to an increase in the concentration of the polishing stone, thereby achieving a strengthening effect. The gloss of the product has reached the ideal requirements, and the gloss is above 85 degrees or higher. Influencing factors of stone polishing machine work Type of polishing agent: Although the polishing agent is a special kind of polishing material, the difference between it and the grinding material is mainly reflected in the processing mechanism. In principle, there are some low-hardness fine powder materials that can also be used as polishing agents. But usually a high hardness polishing agent is better than a low hardness and has a wide range of applications. Polishing liquid: Water is a commonly used polishing liquid. It can not only play the role of grinding and cooling, but also can be used as a physical and chemical role in the polishing medium. If the stone is polished mainly by mechanical grinding, such as diamond powder, the polishing liquid is generally better with organic oil such as sewing machine oil. Its cooling, lubricating and dispersing effects are excellent. Diamond abrasive pastes are available in both water and oil, and can be added with colorants.
Application Fields Of String Light...
the principle of efficiency In the application design, it is necessary to improve the application efficiency of the lighting system on the basis of meeting the functional requirements of the lighting system, and reduce the energy consumption of the system while reducing pollution. To achieve energy saving and environmental protection purposes. In addition, the application design for string light manufacturers. In order to ensure that it has a relatively high application efficiency after being put into use, it should also do a good job of analysis of the local geographical factors and meteorological factors of the project, and conduct detailed investigation and analysis of the actual conditions such as sunshine time, fog hoop weather, and rainy weather. The actual situation to adjust the design plan at any time, and strive to meet the needs of the lighting system to the greatest extent. Traffic safety principles The main purpose of the construction of urban road lighting systems is to ensure traffic safety, and based on this, to improve the efficiency of transportation and provide a safe and comfortable environment for traffic operation. Therefore, in the construction and application of solar street lights, traffic safety principles must be followed. Based on the actual needs of local roads and transportation, a rational design is carried out. Ensure that all aspects of the design meet the requirements for use.

Advantages And Characteristics Of...
In the process of mechanical processing, the common methods of plate cutting are manual cutting, semi-automatic cutting machine cutting and CNC cutting machine cutting. Manual cutting is flexible and convenient, but manual cutting has poor quality, large dimensional error, large material waste, and large amount of subsequent processing work. At the same time, poor labor conditions and low production efficiency. The profile cutting machine in the semi-automatic cutting machine has better quality for cutting workpieces. Because it uses cutting dies, it is not suitable for single piece, small batch and large workpiece cutting. Although other types of semi-automatic cutting machines reduce the labor intensity of workers, their functions are simple and only suitable for cutting some more regular shaped parts. Compared with manual and semi-automatic cutting methods, CNC cutting can effectively improve the cutting efficiency and cutting quality of sheet metal, and reduce the labor intensity of the operator. In China, the use of manual and semi-automatic cutting methods is even more common in some small and medium-sized enterprises. The amount of steel used in China's machinery industry has reached more than 300 million tons, and the amount of steel cut is very large. With the development of modern machinery industry, the requirements for work efficiency and product quality of sheet cutting have also increased. Therefore, the market potential of CNC cutting machines is still very large, and the market prospect is relatively optimistic. After decades of development, CNC cutting machines have made great progress in both cutting energy and CNC control systems. Cutting energy has developed from a single flame energy cutting to multiple energy sources (flame, plasma, laser, high-pressure water jet) Cutting method; CNC cutting machine control system has evolved from simple functions, complex programming and input methods, and low automation to complete functions, intelligent, graphical, and networked control methods; the drive system has also changed from step to step Drive, analog servo drive to today's all-digital servo drive; the main varieties of CNC cutting machines include the following: CNC flame cutting machine CNC plasma cutting machine CNC laser cutting machine CNC high pressure water jet cutting machine Other special cutting equipment Pipe cutting machine, CNC marble cutting machine, other non-metal special cutting equipment, etc.).
