1. The most basic requirement for installing a lamp is that it must be securely fastened to prevent any movement or falling.
2. When installing indoor lighting such as wall lamps, bedside lamps, table lamps, floor lamps, and mirror-mounted lights, if the height is below 24 meters, the metal casing of the lamp should be grounded to ensure safe operation.
3. In bathrooms and kitchens, when using low-profile lamp holders, it’s advisable to use porcelain screw-base bulbs. The live wire (switched wire) should be connected to the center contact point, while the neutral wire should connect to the threaded base.
4. For lamps with built-in switches, like table lamps, safety is key—make sure there are no exposed metal parts at the beginning of the handle to avoid electric shocks.
5. When installing decorative ceiling lamps, always follow the manufacturer's instructions. If the fixture weighs more than 3kg, it should be directly fixed to the ceiling structure using pre-embedded hooks or anchor bolts—not by hanging from the keel or support frame. Also, protect the wiring with a conduit to prevent exposure in the ceiling space.
6. All wiring inside ceilings or walls must be protected by flame-retardant conduits. Special lamps, such as diffused or hidden lighting, require careful installation to maintain both aesthetics and functionality. Many people prefer to hide lights, but proper technique is essential for success.
Some useful tips:
1. Start and finish in alignment. Fluorescent lamps should be installed one at a time, especially if they’re not part of a continuous light strip.
2. Position the highest point of the lamp at the same level as the edge of the ceiling housing to maintain a clean look.
3. Small light tubes (like fluorescent tubes) placed in curved areas are manageable and don’t cause issues.
4. Choose white, yellow, or blue (even purple) for your lighting. Avoid red and green, as they can create uncomfortable or inappropriate atmospheres.
Preparation Steps:
(1) Common Materials
Various types of square wood, slats, aluminum profiles, and other structural materials are used for support. Decorative elements like plastic, acrylic, glass, copper, and anodized aluminum plates are used for finishing touches.
(2) Tools Required
Typical tools include an electric jigsaw, hammer drill, and hand tools like pliers, hand saws, and hammers.
Chandelier Installation:
Large chandeliers are typically mounted using booms or slings under the structural slab or beams, while smaller ones are often attached directly to the ceiling joists.
(1) Connecting Booms or Slings to the Structural Layer
1) Embed iron or wooden blocks into the ceiling structure, ensuring they are strong and positioned accurately with room for adjustment.
2) Use transition pieces to connect the iron or wooden blocks, allowing for error correction through nailing or welding.
3) Attach the boom or sling to the transition piece.
Installation Tips
1) When multiple chandeliers are installed under the same ceiling, adjust their height and position during the ceiling installation for better coordination.
2) For booms passing through the ceiling, consider two methods: direct passage (less visible but harder to locate), or casing method (more flexible and aesthetically pleasing).
3) Ensure the boom has enough thread length for height adjustments. If the light box is suspended, make sure the connection is secure.
Ceiling Light Installation:
Ceiling lights come in two main types: raised and recessed. Smaller ones are usually mounted on the joists, while larger ones are attached via pre-embedded iron pieces or expansion bolts.
Installation Method
1) Ceiling Opening: During the design phase, plan where the ceiling light will go. Create a frame around the light’s outer edge to serve as a mounting structure. Reinforce the opening for large lights.
2) Hanging Ribs and Lamps: For large ceiling lights, install lifting ribs from the structural layer. These can be embedded during slab construction, or added later for accuracy. Connect them to the light’s support frame for stability.
3) Assembled Ceiling Lights: These are made by combining ordinary lamps (fluorescent or incandescent) with decorative elements like glass or acrylic panels. The process involves creating a connecting piece on the ceiling, attaching booms and hangers, then installing the lamps and panels. Pay attention to positioning and flatness during installation.
(1) Lighting Layout
1) Luminous Belt: A long, sliding light strip made with frosted or colored glass panels.
2) Lighting Ceiling: Four common arrangements:
• High-Hanging: Placed above the ceiling surface to create soft, even lighting.
• Inlay: Embedded within the ceiling, matching its surface level.
• 8-Ceiling: A set of lamps mounted under the ceiling surface, offering flexibility in placement.
• Hanging: Can be straight or angled, with many options for light sources and combinations.
(2) Installation Notes
1) Before starting, understand the luminaire’s design, size, and connection details. Plan the embedded parts, opening sizes, and reinforcement needs. For large fixtures, consider separate rib embedding rather than using nails or bolts.
2) Ensure the edge of the ceiling light covers the panel to avoid gaps or uneven finishes.
4. Illuminating belts and lighting ceilings are similar to other ceiling fixtures, but they often feature larger layouts and different visual expressions. They are commonly used in open ceilings to complement architectural elements or be integrated directly into the design.
