How to route indoor lighting in the intelligent era?

LED semiconductor lighting network lighting as an important part of smart home, even how intelligent control, wireless communication technology how to innovate, wireless transmission of energy in the long-distance, so sci-fi technology before the implementation, we have to A large number of cables live together to participate in lighting and controlling lighting equipment. The indoor lighting circuit is mainly composed of three types: clear wiring, dark wiring, and light and dark hybrid wiring.

Ming-laying wiring—that is, there is no decorative ceiling board in the room, the line is laid along the top surface of the wall and the floor, or there is a decorative ceiling board in the room, and the line is laid along the outer surface of the wall body and the ceiling board, which can directly see the laying method of the line direction. , said the clear wiring.

Concealed wiring - refers to the line laying along the wall, in the decorative ceiling or in the top of the floor, can not directly see the line of the dark wiring. In the construction of the building, indoor lighting sockets, weak wires, etc., are fixed in the cement board, and can not be changed after pouring. In home installations, it is common to slot the wall to a socket or switch or a small electrical box. When it is necessary to pass through the entire room, it is usually slotted on the ground. You can also use the ceiling or roof corner line to walk the pipeline.

Light-dark hybrid wiring - it is characterized by the fact that some of the lines are visible and the other part of the line is not visible. For example, in some interior decoration projects, the electrical design, the dark part of the wall part is taken, and the top part of the decorative hang is wired.

Among them, the commonly used wire-bonding methods include direct wire laying, wire-passing, and wire-growing of insulated wires:

Direct line

When laying the insulated wire directly, pay attention to two points when laying:

1. The sheathed insulated wire shall be used for direct wiring in the house, the cross section shall not be greater than 6mm2, and the fixed point spacing of the wiring shall not exceed 300mm;

2. In the roof shed of the building, in the wall, and in the column, it is strictly forbidden to use the insulated wire for direct or clear wiring, and the metal pipe and the metal wire slot must be used.

Pipe routing

When the insulated wire is laid through the pipe, the voltage level should not be lower than 750V.

1. Welded steel pipe shall be used for wire laying in a wet environment or directly buried in the soil. Wire or steel pipe or galvanized steel pipe with a wall thickness of not less than 1.5 mm may be used for wire laying in a dry environment or in a dry environment.

2. In the environment where the acid and alkali salts corrode the medium, the flame retardant plastic tube should be used for corrosion, but it should not be used in places where mechanical damage is appropriate. When laying dark or buried, the section leading out of the ground shall take measures to prevent mechanical damage; in dangerous explosive environments, galvanized steel pipes shall be used;

3. When more than 3 insulated wires pass through the same pipe, the total cross-sectional area of ​​the wire (including the outer sheath) should not be greater than 40% of the net area inside the pipe. When the two wires pass through the same pipe, the inner diameter of the pipe should not be less than 2 1.35 times the sum of the wire diameters;

4. When laying the electric wire tube, hot water pipe and steam pipe at the same time, it should be laid under the hot water pipe and steam pipe; when there is difficulty, it can be laid on the top, and the distance from the hot water pipe is not less than 0.3m, in the steam pipe The above is not less than 1.0m; the parallel clearance of the wire tube and other pipes should not be less than 0.1m.

5. The AC line through the metal pipe should be such that all phase and neutral lines are in the same pipe;

Trunking wiring

Trunking wiring should be used in locations that are dry and less susceptible to mechanical damage. The trunking has plastic (PVC) trunking, metal trunking, ground trunking, and the like. The grounding trough is connected to a distribution or distribution tray every 4~8m. It is very easy to pull the cable when it is in Pucheng, so the distance is not limited. Strong and weak power can be routed to adjacent ground troughs, and can be connected to their respective sockets in the same line box. Of course, the ground trough must be grounded and shielded, and the quality of the product must pass. If the office or business hall is large, the computer is far from the wall. If you use a long jumper to connect directly to the wall's information outlets and power outlets, it's obviously not appropriate. At this time, leaving a outlet box near the ground slot can solve the problem of network access and power supply at the same time.

Conclusion

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 will have a breakthrough in smart home. With the management and control of data between IoT technologies, the development of smart homes will achieve greater success, and at the same time, the comprehensive wiring will be a breakthrough in the field of smart home applications, prompting the integrated wiring to keep up with the pace of life and adapt to the rhythm of life. .
