1 How do we explain “CRI” ?
RE: 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.
2 What’s CCT(colour temperature) ?
RE: 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.
3 Do you know “dali “?
RE: Digital addressable lighting interface (DALI) is a trademark for network-based systems that control lighting in building automation.
4 What’s the fire rating categories ?
RE: 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.
5 How to explain “Flux/luminous Flux “?
RE: Luminous flux is the measure of the perceived power of light produced by the LED, adjusting to reflect the varying sensitivity of the human eye to different wavelengths of light.
6 Why we use the high power LED?
RE: A high power LED, sometimes referred to as a power LED, is one that is driven at current of 350mA or higher.
7 How to explain “illuminance“?
RE: The intensity of light falling on a surface area. If the area is measured in square feet, the unit of illuminance is footcandles(fc). If measured in square metres, the unit of illuminance is Lux.
