1. Ceiling and Top Painting 1) Based on the design elevation of the ceiling, a deviation of ±5mm in the horizontal plane is acceptable. 2) The galvanized iron wire used for the hanging ribs should be no less than size No. 8, and expansion bolts must be used as lifting points. 3) If wooden keels are used, they must be made of non-cracked, non-twisted red or white pine. The main keel should not be smaller than 50mm × 70mm. 4) Paint should be applied directly onto the drum, ensuring a flat top surface with no noticeable depressions. 5) For bathroom ceilings, avoid using gypsum board, mineral wool board, or plywood that may warp due to moisture. Instead, use metal or plastic panels. 6) The surface of the cover panel should be smooth, with straight and evenly spaced seams, and free from defects like missing corners or cracks. 7) The joints between the cover panel and the keel or dragon bone must be tightly connected, secure, and not loose. 8) All wooden keels must be treated with fireproof coating. Additionally, those in contact with walls or installed in bathrooms should also be coated with preservatives. Note: Wooden keels are rarely used in standard renovations and are more common in high-end projects. 2. Tiling, Wallpaper, and Painted Walls 1) The wall surface must be flat and smooth. When touched by hand under light, it should not cause serious reflection. Corners should be straight and square. 2) At the corner of the wall, the wallpaper or wall covering should overlap and be tightly pressed without leaving any visible seams. 3) Quality wallpaper and wall coverings should have no bubbles, hollow sounds, cracks, curled edges, wrinkles, or stains. They should be firmly attached and maintain consistent color. 4) Items like wallpaper, wall coverings, mirror lines, door and window trims, curtain boxes, and baseboards should fit snugly against the wall with no gaps. 5) Seams should be straight and aligned, with consistent patterns and no overlaps or separations. From at least 1 meter away, the seams should not be visible. 6) Partial tiles around protrusions (such as pipes) should be cut precisely to match the shape, with even edges. 7) Tiles should be firmly adhered, with no empty drums, color differences, or issues like skewing, chipping, or cracking. 8) Seam height should be about 5mm, and the wall surface should be flat with vertical deviations not exceeding 2mm. 3. Tile Flooring and Wooden Flooring 1) Common floor materials include marble, granite, and ceramic tiles, all bonded with cement or adhesive. The surface should be uniform, smooth, and consistent in texture, pattern, and color. 2) The top and bottom layers must be fully bonded. Knocking on the surface should not produce any hollow sound. Joints should be straight, with even spacing and firm adhesion. 3) Wooden keels, flooring, and subfloor materials must be sturdy and straight. It’s recommended to treat them with preservatives. 4) Hardwood flooring should be nailed to the middle of the four sides. A 5–10mm gap should be left between the floor and the wall, covered by the baseboard to create a "horse foot" effect. 5) The joints should be tight with no visible traces. Staggered joints and firm nails are essential. The floor should feel solid with no looseness or noise. 6) The wooden floor surface should be smooth, free of splinters, scars, or uneven coloring. The grain should be clear, and the finish should be even and natural. 4. Wood Products (Cabinets, Siding, Doors, etc.) 1) Cabinets and wall units should be securely installed, with no looseness or deformation. Corners should be neat, doors should open and close smoothly, and there should be no hammer marks or exposed nails. 2) The upper and lower edges of moldings, curtain boxes, and door trims should not exceed 2mm in deviation. Verticality should also be within 2mm. Use a plumb line for inspection. In short: horizontal and vertical are the key criteria. 3) The siding surface should be smooth and even. If patterns are used, the width and spacing should be consistent. Avoid hammer marks, dirt, or nail caps, and ensure straight edges. 4) Joints on door trims, mirror lines, and curtain boxes should be tight, with 45-degree angles and no gaps. They should fit closely against the wall. 5) After painting, check for leaks, sanding, brush marks, stains, or peeling. The surface should be smooth and even. If using water-based paint, the wood grain should be visible. For oil-based, the color should be bright and uniform. Always inspect before painting—defects are hard to fix afterward. 5. Water Supply and Drainage Pipes, Sanitary Fixtures 1) Pipe installation should be straight and level, with unobstructed flow. Valves should be placed in accessible positions for future maintenance. 2) If installing hidden pipes, test for leaks after completion. Check all joints, valves, and connections for seepage before sealing. 3) Sanitary fixtures should be installed after the ceiling is complete. Ensure proper installation of pipes for bathtubs, toilets, sinks, and wash basins. Carefully check for leaks. A single leak can cause major damage and costly repairs. 4) Accessories like mirror boxes, soap dispensers, towel bars, and shower rods should be securely fastened (preferably with expansion bolts), properly positioned, and free from damage. Faucet covers should fit tightly against the wall. 6. Electrical Wiring (Phone, TV, Power) 1) Concealed wiring should be placed in protective tubes, preferably PVC flame-retardant or metal. Wire joints should be inside junction boxes, not wrapped in cloth or buried in walls. 2) Different wires should be used for different purposes. Telephone lines require special sheathed cables, while cable TV needs 75-ohm coaxial cables. Lighting circuits should be at least 1.5mm², and air-conditioning lines at least 2.5mm². High-power appliances may need 4mm² or larger. 3) Power, phone, and TV cables should not share the same tube. Use concealed outlets and switches, and install a leakage protector if possible. Wire ends in junction boxes should be left with at least 15cm for future access. Before closing walls, double-check all connections. 4) Large chandeliers and fans should be mounted with steel bars over 8mm in diameter, embedded in the ceiling and securely fixed. The minimum distance from the floor should be 2.3 meters. 5) Wall lamps and chandeliers should be fixed with expansion bolts. The chandelier’s center should align with the support rod, and the power cord should not bear the weight of the fixture. 6) Exhaust hoods must be installed according to manufacturer instructions, with correct height and angle. Supervise the installation process carefully, especially for multi-connectors. Once buried, it's hard to recheck. Ensure all connections are functional and meet standards.
The controller features various adjustable parameters such as light intensity, duration, and color temperature. Users can easily program the lights to simulate natural sunlight or create specific lighting conditions for optimal plant development. The controller also offers the convenience of scheduling lighting cycles, ensuring plants receive consistent and appropriate light exposure.
The function of the controller for plant lights is to control the switch, brightness, spectrum and light time of the lamp to meet the needs of plant growth. Through the controller, suitable light conditions can be set according to different plant species and growth stages, providing suitable light energy supply, promoting plant photosynthesis and growth and development. The controller can also adjust the brightness and spectrum of the lamp as needed to simulate different natural lighting conditions and help plants grow in different environments. In addition, the controller can also set the lighting schedule, automatically control the switch of the light, realize the function of turning the light on and off at a certain time, provide a stable lighting environment, and facilitate the management and care of plants. In short, the controller is an important part of the plant lamp, which can effectively control the parameters of the lamp, provide suitable lighting conditions for the plant, and promote the healthy growth of the plant.
