The application of LED bracket lights in our lives is very extensive. Before using them, everyone should first understand the installation steps, which need to follow several steps: preparation before construction, cable laying, the distribution box that needs to be drilled, threading, grounding, inspection, and system debugging. In this article, I not only introduced the installation steps but also analyzed the specific reasons for the LED bracket light flickering after being turned on. Friends who are interested can take a look together!

Specific steps for installing LED bracket lights:

1. Preparation before construction

Make sure to provide technical disclosure, understand the drawings and grasp the design intent, and cooperate with other professional work. Proper protection of finished products and coordination among various professions should be ensured.

2. Cable laying

Electrical performance tests should be conducted beforehand, and construction can only proceed after passing. The cable laying should be arranged reasonably according to its direction and specifications, and generally, there should be no crossings.

3. Distribution box that needs to be drilled

Holes must be drilled using a hole opener, and cutting holes with gas welding and other methods is strictly prohibited. There should be protective pipe caps where wires enter the distribution box and junction boxes, and measures should be taken to prevent foreign objects from falling in before threading.

4. Threading

Wires should not have joints or be tangled inside the pipes or grooves. Protective wire sleeves should be installed at the exit, and relevant voltage tests should be conducted. The insulation resistance should also meet the specified values, and records should be kept.

5. Grounding

There should be grounding for the distribution box and protective grounding for each system. Working grounding should be connected to the original grounding network to improve the entire grounding system.

6. Inspection

After installation is completed, an inspection should be conducted to confirm that everything is correct before proceeding to sub-item debugging and keeping debugging records.

7. System debugging

After completing sub-item debugging, conduct system debugging, linkage debugging, and trial operation, and keep records. The installation of other electrical equipment should strictly follow the drawings.

Reasons for the LED bracket light flickering after being turned on:

1. The LED beads of the LED bracket light do not match the LED driver power supply. Normally, a single 1W LED bead can withstand a current of 280-300 mA and a voltage of 3.0-3.4 volts. If the LED bead chip is not of sufficient power, it will cause flickering of the light source. If the current is too high for the LED bead to withstand, it will turn on and off, and in severe cases, it can burn the internal gold or copper wire of the LED bead, causing it to not light up.

2. It may be that the driver power supply is faulty. As long as another good driver power supply is replaced, it will stop flickering.

3. If the driver has over-temperature protection, and the material of the lamp cannot meet the heat dissipation requirements, the over-temperature protection of the driver will start working, resulting in flickering. For example, if a 20W floodlight shell is used to assemble a 30W lamp, and the heat dissipation work is not done well, this will happen.

4. If outdoor lamps also have flickering on and off, it means that the lamp has water ingress. The consequence is that it will flicker and then stop lighting up. Both the LED bead and the driver will be damaged. If the driver is well waterproofed, only the LED bead will be damaged, and replacing the light source will suffice.

The above is what I have introduced regarding the specific steps for installing LED bracket lights and the reasons for flickering after being turned on. If you have any doubts, feel free to contact us in a timely manner!
