Marking and replacing them in time can help save energy and reduce emissions. In summary, marking broken lamp beads is an effective management method that helps to improve maintenance efficiency, prevent safety hazards, record maintenance history, and control costs.
Therefore, this practice is widely adopted in the daily maintenance and management of lighting systems.
2. What are the wrong ways to mark broken lamp beads?
If the method for marking broken lamp beads is improper, it may cause confusion, misunderstanding, or inefficient repair. Here are some possible mistakes when marking damaged lamp beads:
1). Unclear or fuzzy markings:
If the marking method used is not clear or easy to fade, such as lightly drawing a circle on the lamp bead with a pencil or using stickers that are easy to fall off, then the markings may become difficult to recognize or even disappear completely over time.
This will cause the maintenance personnel to research for the bad lamp bead during the inspection, increasing the workload.
2). Improper marking position:
If the mark is not directly attached to the bad lamp bead or is attached to a position that is easily obscured, such as the side or bottom of the lamp bead, then when the display is on, the marks may be blocked by light and difficult to find.
In addition, if the mark is attached to a position that is easy to fall off or wear, such as near the pins of the lamp bead, it may also cause the marking to fail.
3). Inconsistent marking methods:
If different maintenance personnel use different marking methods during the repair process, such as some use stickers, some use pens, and some use labels, then this may cause confusion.
When others take over the repair work, it may take extra time to interpret these marks, reducing work efficiency.
4). Incomplete or wrong marking information:
If the marking only contains the location information of the bad lamp bead but does not contain other important information (such as the lamp bead model, specifications, replacement date, etc.), then additional difficulties may be encountered when replacing the lamp bead.
In addition, if the marking information is wrong (such as mislabeling a good lamp bead as a bad lamp bead), it will lead to unnecessary repair work.
5). Use fragile materials or tools:
If fragile materials (such as ordinary paper, tape, etc.) or tools (such as sharp objects) are used to mark the bad lamp bead, it may cause damage to the marking or scratches on the surface of the lamp bead.
This will not only affect the clarity of the marking but may also cause damage to the lamp bead itself.
