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.
