The reporter has received a lot of chandeliers and ceiling lamps. The small size of the apartment, the use of complex fancy chandeliers is easy to visually lower the height. Good-looking European chandeliers are difficult to clean and manage, which is more troublesome. The ceiling lighting is not enough. At night, we have to add a desk lamp for the work. The reporter has received a lot of chandeliers and ceiling lamps. In this regard, the designers suggest: may wish to give the home living room, restaurant, aisle, hall lighting to the spotlights, energy saving, easy to clean, easy to manage, good maintenance, long life, brightness is enough. Clever use of spotlights will find it has advantages over single illumination sources such as chandeliers and ceiling lamps. Spotlights can completely replace chandeliers and ceiling lamps. In the old-fashioned decoration of many families, spotlights are only auxiliary light sources for ceiling lamps or chandeliers. They are glare, high temperature and reflective, and are decorative without substance. This is a misunderstanding of many owners of spotlights. Some old-fashioned spotlights do not handle the optical parts, causing user confusion. However, many households have completely replaced chandeliers and ceiling lamps with modern design spotlights, which has gradually become a trend. The directivity of the shooting light line is strong, there is no lighting dead angle, the light is downward, the ceiling is hidden in the dark, and the height can be visually improved. The reporter saw at the home store that there are many choices for the angle of illumination (beam angle) of the spotlights, there are 15, 30, 45, 60, the beam angle is small, it will have a concentrated effect, and the spotlight is hard, suitable for illuminating specific items. For example, the decorations in the home; there are 120, 180 choices, the beam angle is large, it will show astigmatism, soft astigmatism, mainly used for lighting. Philips lighting sales staff told reporters: If properly matched and used, a group of spotlights can completely replace traditional chandeliers and ceiling lamps, with low prices and good results. How to choose the right spotlights Common spotlights are not LED lights. Compared with incandescent lamps, fluorescent lamps, and energy-saving lamps, LED lamps have higher photoelectric conversion rates, and LED lamps are more energy-efficient at the same brightness. According to the calculation data, the power consumption of the LED lamp is only 1/3 of the energy-saving lamp, which is more energy-efficient than the incandescent lamp. With LED lights, you can also design a lot of beautiful shapes. In the LED light, there is a COB lamp, which is not only better in the process than the traditional lamp, but the most important thing is that the user experience is greatly improved. In the near future, the bulb has no distinct glare and photoelectricity, but the light is uniform. No ghosting. When purchasing spotlights, consumers need to experience it themselves and whether there is glare after turning on the lights. According to industry insiders, the spotlights are highly directional, and optical refraction may have glare into the eyes. It is easy to glare and dizzy when used for a long time. If the luminaire manufacturer handles the optical part well, glare is completely avoidable. In addition, poor quality LED lights, lack of blue light filtering is easy to damage vision; and high-quality brand lamps will indicate product parameters, including color temperature, luminous flux (brightness), color rendering index, and illuminating angle, which are important indicators for consumers. Purchase. In addition to LED lights, traditional spotlights can also use halogen lamps, which is the mainstream product of spotlights in old-fashioned decoration. The principle of illumination is similar to incandescent lamps, which is highly recognized among older owners. This kind of lamp has good color rendering and low price, and it is still recognized by many consumers in the market. There are many ways to install spotlights. There are various ways to install spotlights. Different functional areas in the room are suitable for different installation methods. The spotlights can be installed, that is, the spotlights can be installed without the ceiling, the entrance hall entrance, the top of the bathroom corridor, and the top of the dining table, which are more suitable for installing the spotlights. The concealed hanging spotlight is installed in the ceiling of the spotlight. From the outside, the spotlight is directly embedded in the chandelier. This method is suitable for installation in the living room and has a high aesthetic appearance. Mr. Wang, the construction engineer of Huayou Decorative Water Circuit, said: In the past, the ceiling was not more than 10 centimeters thick, and a large part of the floor was eaten. Many families were hesitant to make a ceiling. But now the ceiling of the LED spotlight can be made very thin, 5-7 cm can be used for pure spotlight illumination. Therefore, young owners are more likely to accept this spotlight installation method. However, it should be noted that after the ceiling of the living room is concealed, the spotlights need to be evenly distributed so that every corner of the room can be illuminated, unlike the ceiling lamps and chandeliers, which make the room dark and dead. Philips spotlight sales staff told reporters: If it is a living room of 10 square meters, 6-8 ç› spotlights are enough to use, can shine full house. If it is a living room of more than 20 square meters, the number and position of the spotlights can be arranged according to the size of the living room, which can achieve satisfactory lighting effects. If you do not plan to ceiling, you can choose the spotlights in the living room. The track can be electrically conductive. The spotlight can be illuminated on the track. The position of the lamp can be changed on the track at any time, which is convenient for future lamp replacement and lamp removal. Change lights. This kind of track spotlight is suitable for living room and dining room, as well as dining table, bar, desk and other areas that need extra key lighting. When installing, a conductive track is arranged along the plaster line to the sides of the wall, which not only can provide illumination, but also It can illuminate the coffee table, the side, the plants on the wall, the decorations, and so on. Walk a back-shaped track in a functional area, and the lighting has no dead ends. When installing, it is necessary to keep the wire position in advance during the hydropower transformation, and all the spotlight installation positions need to be fixed in advance to facilitate future construction. If the old room is converted into a spotlight, it can directly replace the ceiling lamp or chandelier. When installing, install a spotlight with a base multi-lamp at the interface of the original chandelier, and it can be completely replaced. The spotlights can be directly inserted into the original ceiling lamp position, and the number of lamps can be adjusted according to the lighting needs. If you are renovating the spotlights in the old bedroom, remember to direct the lamp head directly to the bed or at the end of the bed, and illuminate the space by reflecting light, so that the light is soft and not glare.
Stainless Steel Pipe is a hollow round steel, mainly widely used in petroleum, chemical, medical, food, light industry, machinery and instruments and other industrial transportation pipeline and mechanical components, etc..

Hardness
Stainless steel tubes are commonly used in general, the Vivtorinox three hardness indicators to measure the hardness.
Vickers hardness
Vivtorinox hardness test is a kind of indentation test method, which can be used to measure the hardness of thin metallic materials and surface layer. It has the main advantages of the method of the method of the law of the family and the law of the law, but it is simple and easy to use, but it is not easy to use the method of the Vivtorinox method.
Hardness test
Stainless steel tube inner diameter above 6.0 mm, wall thickness in 13mm following annealing of stainless steel tubing can used to W-B75 type Merriam Webster Hardness Meter, it tests the very fast and easy, suitable for of stainless steel pipes do quick and nondestructive inspection. The inner diameter of the stainless steel tube is larger than 30mm, and the wall thickness is larger than that of 1.2mm stainless steel pipe. The hardness of HRB and HRC is tested by using the hardness tester. Stainless steel tube inner diameter greater than 30mm, wall thickness less than 1.2mm of stainless steel pipe, using the surface of the hardness tester, test HRT or HRN hardness. The inner diameter is less than 0mm, more than 4.8mm of stainless steel pipe, using the tube special for the hardness tester, test HR15T hardness. When the inner diameter of the stainless steel pipe is larger than 26mm, the hardness of the inner wall of the tube can be tested by the tester of the surface of the tube or the surface of the hardness tester.
