FAQ For LED Lights

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.

How do we explain "CRI"?

A measure of the degree of color shift objects undergoes when illuminated by the light source as compared with those same objects when illuminated by a reference source of comparable color temperature. The reference source has a CRI of 100.

What is CCT(Color Temperature)?

The description used to describe the effect of heating an object until it grows incandescently. The emitted radiation, and apparent color, changes proportional to the temperature; easily envisioned radiation, and apparent color, changes proportional to the temperature; easily envisioned, when considering a hot meal in a forge that glows red, then orange, and then white as the temperature increases.

What is the fire rating categories?

VO-Burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.

HB-Slow burning on a horizontal 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.

How to explain "Flux/luminous Flux"?

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.

Why we use the high power LED?

High power LED, sometimes referred to as a power LED, is one that is driven at the current of 350mA or higher.

How to explain "illuminance"?

The intensity of light falling on a surface area. If the area is measured in square feet, the unit of illuminance in footcandles(FC). If measured in square meters, the unit of illuminance is Lux.

What is efficacy about the light?

The light output of a light source divided by the total electrical power input to that source, expressed in lumens per watt(Lm/W).

How important is IP?

Classifies and rates the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accidental contact, and water by the mechanical casing and electrical enclosures.

What is Watt?

The unit of electrical power as used by an electrical device during its operation. Many lamps come with ratings in watts to indicate their power consumption.

What is LED Chips?

The light producing semiconductor device that may or may not is incorporated into an LED.

Could i tell you what is LED driver?

An electronic circuit that converts input power into a current source -a source in which currently remains constant despite fluctuations in voltage fluctuations, over voltages, and voltage spikes.

What is LGP (PMMA)?

A key component to maximize the uniformity of light, to make the backlight slim and to reorient the line or dot light source such as LED to the plate light source.

What is Lumen?

The international (SI) unit of luminous flux or quantity of light and equals the amount of light that is spread over a square foot of surface by one candle power when all parts of the surface are exactly one foot from the light source.

What is power factor?

The active power divided by the apparent power (i.e product of the RMS input voltage and RMS input current of a driver.)

How to explain "Luminous Efficacy"?

A measure of how well a light source produces visible light expressed as Lumens /Watt.
