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.
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.
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.
What’s efficacy about the light ?
RE: 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 ?
RE: Classifies and rates the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accident contact, and water by mechanical casing and electrical enclosures.
What’s LED Chips ?
RE: The light producing semiconductor device that may or may not be incorporated into an LED.
Could i tell you what’s LED driver ?
RE: An electronic circuit that converts input power into a current source -a source in which current ramains constant despite fluctuations in voltage fluctuations ,overvoltages, and voltage spikes.
What’s LGP(PMMA)?
RE: 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’s Lumen?
RE: 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’s Power factor ?
RE: The active power divided by the apparent power (i.e product of the rms input voltage and rms input current of a driver.)
What’s Smart Lighting ?
RE: Automated lighting control using sensors and /or scheduling switches.
What’s Watt ?
RE: The unit of electrical power as used by an electrical device during its operation. Many lamps come with rating in watts to indicate their power consumption.
How to explain “ZigBee“ ?
RE: A low -power ,low date rate, local area wireless network; ideal for lighting control.
How to explain “lumen output “ ?
RE: The total lumens emitted of a light source, system, or solution.
How to explain “luminous Efficacy“ ?
RE: A measure of how well a light source products visible light expressed as lumens /Watt.
