Cleaning Steps:

1. Turn off the power: Ensure the LED Step Light is disconnected from the power source to avoid electric shock.
2. Dust removal: Use a dry microfiber cloth to gently wipe off dust and debris from the metal surface.
3. Apply polish: Evenly apply the dedicated metal polish onto the microfiber cloth, avoiding direct spraying on the LED Step Light surface.
4. Polish the surface: Wipe the metal surface in gentle circular motions until it restores its shine. For stubborn stains, increase the wiping intensity slightly, but avoid scratching the surface.
5. Clean residue: Use a clean microfiber cloth to wipe off any excess polish, ensuring no residue remains.

Precautions:

• Avoid using acidic cleaners such as vinegar or lemon juice, which may corrode the metal surface.
• If any scratches or damage are found on the metal surface during cleaning, contact a professional maintenance personnel promptly.

Cleaning Plastic/Acrylic Lampshades

Tools and Materials:

• Slightly damp cloth: Keep it moderately moist, avoiding dripping water.
• Neutral cleaner: Such as dishwashing liquid or soapy water, avoiding alcohol, acetone, or other organic solvents.

Cleaning Steps:

1. Turn off the power: Ensure the LED Step Light is safe and avoid the risk of electric shock.
2. Moisten the cloth: Dip the slightly damp cloth into the neutral cleaner solution and wring it out until it is not dripping.
3. Wipe the surface: Gently wipe the plastic/acrylic surface in straight lines or circular motions to remove dust and stains.
4. Clean residue: Use a clean, slightly damp cloth to wipe off any excess cleaner, ensuring no residue remains.
5. Dry the surface: Use a dry, soft cloth to wipe the surface, accelerating water evaporation and avoiding water stains.

Precautions:

• Avoid using alcohol, acetone, or other organic solvents, which may damage the plastic/acrylic surface.
• If any cracks or discoloration are found on the surface during cleaning, replace the part or contact professional maintenance personnel promptly.

Cleaning Glass Lenses

Tools and Materials:

• Optical cleaning kit: Includes an anti-static brush, lens paper, and other dedicated tools.

Precautions:

• Avoid using regular paper towels or rough cloths to wipe the glass lens, as they may leave scratches or fibers.
• If any scratches or damage are found on the glass surface during cleaning, contact professional maintenance personnel promptly or replace the part.

Detailed Cleaning and Maintenance Procedures for LED Step Lights

Precision Cleaning Process

To maintain the pristine condition of LED Step Lights and ensure optimal lighting performance, a meticulous cleaning process is essential. This process involves daily surface dusting and specialized treatment for stubborn stains.

Surface Dusting

Frequency: Daily

Tools: Electrostatic duster

Procedure:

• Gently brush the surface of the LED Step Light using the electrostatic duster to remove loose dust and debris.
• Pay special attention to crevices and hard-to-reach areas where dust tends to accumulate.
• This daily dusting routine helps prevent the buildup of dust, which can not only obscure the light but also potentially scratch the surface over time.

Stubborn Stain Treatment

Tools: Steam cleaner (temperature controlled below 40℃), microfiber cloth

Procedure:

• For persistent stains that cannot be removed by regular dusting, use a steam cleaner set to a temperature below 40℃ to avoid damaging the LED Step Light‘s surface.
• Hold the steam cleaner at a safe distance from the LED Step Light and apply steam evenly to the stained area.
• After steaming, use a microfiber cloth to gently wipe away the loosened stains.
• Ensure the LED Step Light is completely dry before turning it on to prevent any potential electrical hazards.

Waterproof Grade Inspection

Before performing any wet cleaning on LED Step Lights, it is crucial to check their waterproof grade to avoid damage.

• IP65 Rated and Above:LED Step Lights with an IP65 rating or higher are designed to withstand direct water jets from any direction. These can be safely cleaned with a damp cloth.
• Standard Models: For LED Step Lights without an IP65 rating, it is recommended to use a protective cover before cleaning to prevent water from entering the internal components. Alternatively, use a dry cleaning method to avoid any risk of water damage.

Condition Inspection Checklist

Regular inspections are vital to identify potential issues early and prevent more serious problems from arising. A comprehensive inspection checklist should include the following:

Weekly Inspections

• Fixed Screw Torque: Check the torque of all fixed screws using a torque wrench. The torque should be within the range of 0.8-1.2N·m to ensure secure fastening without over-tightening.
• Connection Wire Insulation: Inspect the insulation layer of all connection wires for any signs of cracking or damage. Replace any damaged wires immediately to prevent electrical hazards.

Monthly Inspections

• Light Source Color Temperature Shift: Use a spectrophotometer to measure the color temperature shift (Δu’v’) of the light source. Ensure that the shift is within the acceptable range of ≤0.005 to maintain consistent lighting quality.

Quarterly Inspections

• Grounding Resistance Value: Measure the grounding resistance value using a grounding resistance tester. The value should be ≤0.5Ω to ensure proper grounding and prevent electrical shocks.
• Driver Power Supply Ripple Factor: Check the ripple factor of the driver power supply using a ripple factor tester. The ripple factor should be <5% to ensure stable and efficient operation of the LED Step Light.
