Students' Questions: What are the precautions for the lighting installation budget?
Answer: When planning the lighting budget, there are several key factors to consider. First, when calculating the average control area per luminaire, if you're using light strips, you should apply a conversion factor—0.3 for incandescent lamps and 0.5 for fluorescent ones. Then, add the number of other types of lamps. A light strip is defined as an incandescent lamp installed in a slot. If the distance between each lamp is less than 50cm, it's considered a "light band." If it's more than 50cm, it doesn't qualify as a light band.
Second, the installation method of the lights depends on their weight. For lamps weighing less than 1kg, a hanging wire is usually sufficient. If the weight exceeds 1kg, chain or pipe suspension is recommended. For heavier fixtures over 3kg, it’s necessary to embed bolts or metal components into the ceiling for secure mounting.
Third, when installing recessed downlights, make sure to use a single cover with a sub-head for the ceiling-mounted fixture. This ensures proper alignment and ease of maintenance.
These points are based on common challenges students face during real-world installations. They are meant for reference only. If you encounter any issues or have further questions, feel free to discuss and correct them promptly. Always double-check specifications and consult with professionals when needed.
