Indoor lighting as an important part of the smart home, even if how the intelligent control, wireless communication technology and how to innovate, in the ultra-long-distance wireless transmission of electricity, so science fiction technology before the realization, we still have to live with a large number of large numbers of cables, used to participate in the lighting and control of lighting equipment. Indoor lighting wiring is mainly by the open wiring, dark wiring and mixed dark and light wiring three categories.

Laying line - that is, there is no indoor decorative ceiling panels, lines along the walls and floors of the top surface of the laying, or indoor decorative ceiling panels, and lines along the walls and ceiling panels along the outer surface of the laying, can directly see the line towards the laying method, called the open laying of the line.

Concealed wiring - refers to the line along the wall, decorative ceiling or floor within the roof laying, can not directly see the line towards the said concealed wiring. In construction, indoor lighting outlets, weak wires and other fixed through the pipe, was poured in the cement slab, poured and can not be changed. In home furnishings, usually in the wall slots to take the pipeline to the socket or switch or small electrical box. When it is necessary to run through an entire room, the conduit is usually slotted in the floor. It is also possible to utilize suspended ceilings or shady roof corners for conduit routing.

Mixed dark and light wiring - characterized by a part of the line is visible towards the other part of the line is not visible towards the laying method. Such as in some interior decoration projects, its electrical design, in the wall part of the dark wiring, into the decorative ceiling part of the open wiring.

One of the commonly used laying methods are insulated wires directly, through the pipe wiring, wire groove wiring:

First, directly laid line

Insulated wires laid directly in the laying should pay attention to two points:

1. In the house directly laid wiring should be used sheathed insulated wire, its cross-section should not be greater than 6m ㎡, wiring the fixed point spacing should not be greater than 300mm;

2. In the building roof shed, walls, columns are strictly prohibited the use of insulated wires straight or open wiring, must use metal pipes and metal trunking wiring.

Second, through the pipe wiring

Insulated wires through the pipe, then note that its voltage level should not be lower than 750V AC.

1, open in a wet environment or buried directly in the soil of the metal pipe wiring, should use welded steel pipe. Open or concealed in the dry environment of the metal pipe wiring, can be used wall thickness of not less than 1.5mm wire steel pipe or galvanized steel pipe;

2, in the environment of acid, alkali and salt corrosive media, should be used flame retardant plastic pipe corrosion, but in the desirable mechanical damage to the place should not be used open laying. Concealed or buried laying, lead to a section of the ground should take measures to prevent mechanical damage; dangerous explosive environment, galvanized steel pipe should be used;

3, more than three insulated wires through the same tube, the total cross-sectional area of the wire (including the outer layer) should not be greater than 40% of the net area of the tube, 2 wires through the same tube, the inner diameter of the tube should not be less than the sum of the diameter of the 2 wires 1.35 times;

4, wire pipe and hot water pipe, steam pipe laid at the same time, should be laid in the hot water pipe, steam pipe below; with difficulty, can be laid on top of the spacing with the hot water pipe is not less than 0.3m, not less than 1.0m above the steam pipe; wire pipe and other piping parallel to the net distance should not be less than 0.1m;

5, wear metal pipe AC line, should make all the phase and zero line in the same pipe.

Third, wire trough wiring

Wire groove wiring should be used for dry and not vulnerable to mechanical damage to the place. Wire duct has plastic (PVC) trunking, metal trunking, ground trunking and so on. Ground trunking every 4~8m connected to a sub-disk or out of the disk. It is very easy to pull the wires in the city, so the distance is not limited. Strong and weak power can go the same route adjacent to the ground wire trough, and can be connected to the same line box in their respective outlets. Of course, the ground wire trough must be grounded shielding, product quality should be over the top. Such as office or business hall area is very large, the computer is far from the wall. If the use of long jumper cables directly connected to the wall information outlets and power outlets, is obviously not appropriate. At this point in the ground near the wire channel to leave a wire box, you can simultaneously solve the problem of network access and power supply.

With the improvement of living standards, home intelligence is a common demand, coupled with the advancement of the Internet of Things, I believe that integrated wiring in the smart home will have a victory breakthrough. With the Internet of Things technology to realize the management and control of data between the development of smart homes will achieve greater success, but also drive the integrated wiring in the smart home applications on the breakthrough, prompting the integrated wiring to keep pace with life, conform to the rhythm of life.
