1.what’s the meaning of “Beam Angle “?
The spread of light from a luminaire . For example: a fitting such as a low bay ,which is closer to the floor,will have a wider beam angle to
illuminate a given floor area while a high bay fitting will have a narrower beam .
2.How do we explain “CRI” ?
A measure of the degree of colour shift objects undergo when illuminated by the light source as compared with those same objects when
illuminated by a reference source of comparable colour temperature . The reference source has a CRI of 100 .
3.What’s colour temperature ?
The description used to describe the effect of heating an object until it grows incandescently . The emitted radiation ,and apparent colour ,
changes proportional to the temperature ; easily envisioned radiation ,and apparent colour ,changes proportional to the temperature;easily
envisioned ,when considering hot meal in a forge that glows red ,then orange ,and then white as the temperature increases .
4.Do you know “dali “?
Digital addressable lighting interface (DALI) is a trademark for network-based systems that control lighting in building automation.
5.What’s the fire rating categories ?
VO-Burning stops within 10 seconds on vertical specimen ; drips of particles allowed as long as they are not inflamed.
HB-Slow burning on a horizonal specimen’s burning rate <76mm /min thickness <3mm or burning stops before 100mm.
TP(b)-Slow burning rate <50mm / min for thickness <3mm.
TP(a)-Self extinguishes and flaming and afterglow should not exceed 5 seconds once source the source of flame is removed .
