1. Maintenance plan - Teamtronic luminaires

In general, EN12464 requires a maintenance plan to be drawn up when a new lighting system is installed. This plan also includes cleaning schedules. When cleaning luminaires, it is important that it is done in the right way so that the luminaire is not damaged.

Maintenance factor When designing lighting systems, luminaire and light source soiling must be taken into account according to EN12464.

2. Maintenance factor

According to DS/EN 12464-1:2011, "the lighting designer (lighting planner) shall state the maintenance factor and list all assumptions used to determine the value." In addition, the lighting planner/designer must prepare a maintenance plan, which must include any light source replacements and cleaning intervals for rooms and luminaires.

DS/EN 12464-1 states that maintenance factors (MF, Maintenance Factor) can be calculated according to CIE 97:2005 Maintenance of Indoor Electric Lighting Systems:

MF = LLMF ∙ LSF ∙ _LMF ∙ _RSMF

3. Material cleaning

Guideline material cleaning Cleaning of the items is carried out with a mild sulfo solution and a water temperature of max. 60 degrees. The use of detergents containing abrasives or solvents may damage the surface and should be avoided.

Hard brushing or scrubbing can damage the surface and should be avoided. Never use high-pressure cleaners on Polycarbonate diffuser for luminaires with a high IP rating, this causes water ingress and damages the material.

For reflector surfaces with a glossy finish, it is recommended to use a dry soft cloth.

It is important that the luminaires are cleaned in the right way so that they are not damaged.

Below is a guide on different surfaces.

  • Painted metal faucet: Damp cloth, mild soap
  • Aluminum reflector: Dry cloth
  • Aluminum grilles: Dry cloth
  • Metal grilles: Damp cloth, mild soap
  • Polycarbonate shield: Water below 60 degrees
  • Acrylic shielding: Water below 60 degrees
  • Glass shielding: Water below 60 degrees
  • ABS plastic: Water below 60 degrees
  • ASA plastic: Water below 60 degrees
  • Acrylic PMMA: Water below 40 degrees
  • Microprismatic shielding: Hard wrung cloth with demineralized water below 40 degrees, no soap
  • Guideline aluminum reflector material: Ensures particles that can scratch the surface are removed before cleaning.

Use one of the following cleaning methods:

  1. Clean with a dry cloth. This method is normally sufficient to remove light surface dust and marks from greasy fingers.
  2. Clean lightly with isopropyl alcohol diluted with water. This method can be used if cleaning is not satisfactory with method 1. Can be wiped with demineralized water.

It is advisable to use plastic gloves when working with reflective material. This is to avoid marks from greasy fingers. Cleaning interval The luminaires are cleaned periodically, depending on soiling, and in connection with light source replacement. Cleaning intervals are carried out according to the maintenance instructions. However, cleaning should be done at least once a year.

Disposal of light sources, burnt out or defective light sources must be disposed of according to the light source manufacturers' instructions.

4. Emergency power luminaires

Emergency luminaires must be function tested once a year, either by disconnection of fixed supply or by built-in test button where internal battery backup is present.

See Appendix 12 to the Building Regulations Guide to chapter 5 - Fire, section 5.5

5. Disposal

When disposing of larger batches of light sources, there may be special rules. See the light source industry's W.E.E.E.E. association www.lwf.nu

Disposal of luminaires All waste electronic and electrical equipment - WEEE - must now be disposed of in a new and better way. To ensure that the system is as efficient, cheap and environmentally friendly as possible, manufacturers and importers of these products have formed Elretur, which ensures that companies can take responsibility together. See the www.elretur.dk

Special precautions If there are special precautions regarding maintenance, these will be stated in the installation instructions.
