The lighting installation needs to meet the lighting principle. The room lighting is not only to illuminate the interior, but to do it according to certain principles, so as to have a good decorative effect and reflect the lighting function. First, lighting must ensure that the various activities required to achieve different lighting. Writings, games, breaks, meetings, etc., should have corresponding lighting fixtures to play any role. This kind of lighting should be a scientific light distribution, so that people do not feel tired, both for the benefit of the eye health, but also save electricity. Second, lighting should be able to set off the room more beautiful. The illumination of light should take care of the contours, levels, and images of the various objects in the room. It should also be able to reflect and even beautify the colors of some special furnishings such as ornaments, paintings, carpets, vases, and fish tanks. Third, lighting should be reliable and safe. Lighting does not allow leakage, fire and other phenomena, but also to open a light, one off. Installation location selection: The position of the light source in the lighting is important, but the choice of position is good, the key lies in what you want the light source to illuminate. The first is people. The most important part of people is the face. Rays projected from different angles will make people's faces have different expression effects. If people stand directly under a chandelier, direct downward lighting will make people's faces cold and serious. If there is a light coming from the bottom up to the face, then worse, the face will become scary and even fierce. Therefore, it is not possible to use direct upward or downward lighting in people's living rooms, dining rooms, sofa groups, etc. If side-shooting direct lighting, that is, to allow light to project from the side, it will make the contour lines of the face rich, clear, such as the use of diffuse lamps, so that scattered light to cast people's faces, will get a clear and amiable image. Followed by lighting the furniture, it depends on what you want to achieve. If it is a new combination of furniture, then it should highlight its color and outline, you can use multi-light source lighting, you can achieve the effect of a few shades of furniture. As an integral part of lighting, lighting must be arranged in different types and locations. Bedrooms often have multiple functions in our country, such as living rooms, study rooms, dressing rooms, and so on. Changing clothes requires uniform light to illuminate from the front of the person in order to obtain a clear image in the mirror, so the light source cannot be placed behind the head of the person. If you want to make-up, set the auxiliary lights on both sides so that the face Wisdom can be clearly seen. To read and write, you need to write a table lamp. When you sleep, the room light can be darker and softer. But before going to bed there are people who read in bed, it is best to adjust the brightness and angle of the bedside lamp. The simple way is to install two lights, one bright and one dark. The function of the living room is more, such as chatting and watching TV and listening to music. If there is a small bar beside the home audio-visual center, then the drink is also here. Do not expect a chandelier to solve all problems. When there are a lot of people, you can use chandeliers, wall lights and the like to get full lighting and even light. In the second and third parties, floor lamps or wall lamps can be used to partially illuminate the coffee table in front of the sofa instead of illuminating the person involved in the conversation. When the audio-visual center is used, only a small 3-watt lamp is used as the background light in the living room to obtain some weak illumination. If the house has a foyer, it is worth to arrange it, because it can affect one's emotions. As soon as we step into our homes, the bright and lively lobby will make people who work for a day feel as if they are in the embrace of the family and feel excited and tired. This requires the installation of an in-line canopy ceiling lamp on the flat top of the entrance hall. When one is not enough, a few can be installed and the color is better. If it is a person who loves art, you can make the walls and flat tops of the foyer and hallways into dark colors and embed a few small lights, making people feel unfathomable, and entering the room immediately is a unique experience. Of course, although this is unique, it is not necessarily acceptable to everyone, because most people are accustomed to behave. The dining room is different from the kitchen. The kitchen is best equipped with a dome light for full illumination, and a separate spotlight for the cooktop to facilitate operation. The dining room is where people eat, and both the East and West attach great importance to the lighting effect here. Westerners pay attention to quiet dining and soft and dark indoor lighting. China has always been proud of its own cooking. Among these, there is absolutely no appreciation for the color of the dishes. This requires that the lights must be bright. For the sake of both considerations, it is recommended to use stretchable hanging fixtures. Not only the retractable wire can freely determine the height of the lamp, but also its red or other beautiful shades can increase appetite. Housing is generally a bathtub in the bathroom, so the bathroom lighting is nothing more than to take into account the functions of both. In the bath, only a simple global lighting is required. When washing and makeup, it is necessary to illuminate the face with light. When washing clothes, it is necessary to see whether the clothes in the washing machine are clean and need local lighting. Therefore, the bathroom only need to install two lights, one is the main light, can be a wall light, can also be a ceiling light, 25-40 watts is enough. The other is equipped with an 8-watt fluorescent lamp above the washbasin. Newly available H lamps or other lamps can also be used. The lighting of the old people should be mainly bright. Some lighter ones can repel loneliness and increase the sense of security. Generally, 40-60 watt incandescent lamps are enough. The lamps used by children should be as lively as possible. According to the actual use of features to be set. The 40-watt desk lamp is enough to read, and do not use fluorescent lamps, because the flicker that the human eye cannot detect with the AC power supply will stimulate the nerves. The lights in the game can be used brightly to illuminate the entire room and make the interior more colorful. At the time of sleeping, a special 3-watt long light can be turned on, which not only solves the child's fear of darkness at night, but also solves the problem of getting up in the middle of the night.

2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.
