LED light

LED light is a lighting fixture using a light-emitting diode(LED), a semiconductor device that emits visible light when
an electric voltage is applied in the forward direction.

Luminous flux

Luminous flux is the measure of the perceived power of thetotal amount of light energy radiated from a light source in acertain direction. The SI unit of luminous flux is the lumen(lm).

Luminous efficiency

Luminous efficiency is the capacity of light flux per watt,
which is calculated with the formula below.
Luminous efficiency [lm/W] = Luminous flux [lm] ÷ Rated
power consumption [W]Colour rendering index (CRI)

CRI is an index used to quantitatively measure light source’s
ability to render the true colours of the object compared to anatural light source. The index is measured from 0 to 100,with a perfect 100 indicating that colours under the lightsource appear the same as they would under natural sunlight.

Downlight/Spotlight

Downlight is downward lighting directly embedded inceiling. Spotlight is downward lighting attached to ceilingmounted wiring ducts.

Reference emissions are calculated with power consumption of project lighting, ratio ofluminous efficiency of project/reference lighting and CO2 emission factor for consumed
electricity.
The luminous efficiency of reference lighting is conservatively set ex ante in the following
manner to ensure the net emission reductions.
1. In Thailand, conventional High Intensity Discharge (HID) lighting is commonlychosen as lighting equipment in case that high performance in colour rendering
property is required. However, LED lighting, which is more efficient than HID
lighting, is adopted as reference lighting in this methodology for conservativeness.
2. The average luminous efficiency value of LED downlight/spotlight commerciallyavailable in the global market is defined as ηRE in each rated power consumption

range, as described in Section I.
