Mechanical requirements of luminaire
If the back plate of the luminaire has insufficient stiffness, the shielding function of the
LED Line live parts of the diffuser is not guaranteed. The diffuser cannot then be safely
applied in a Class I open luminaire. The conditions for the minimum stiffness of the
luminaire back plate depend on profile shape, material and luminaire length. The rule
below takes into account the fact that the luminaire length is approximately the same
as the diffuser length.
The minimum stiffness of the luminaire back plate construction is defined as:
(modulus of elasticity * second moment of area) ≥ 525 * 10
6
[Nmm
2
].
A typical value for the modulus of elasticity for steel is 210,000
N
/
mm
2
.
A typical value for the modulus of elasticity for aluminum is 70,000
N
/
mm
2
.
The second moment of area is dependent on the luminaire shape.
The minimum stiffness is required to make sure that there will be no accessible gap
between diffuser and luminaire back plate when the luminaire back plate is pressed
away from the diffuser with a maximum force of 30N.
Cleaning
Use a damp cloth and only water. Do not wipe the diffuser with a dirty or very wet
dishcloth or towel because they may leave residue that can damage the diffuser.
Installation possibilities
1x LED Line 2ft or
2x LED Line 1ft per diffuser
