Ned Presentation provides an overview of LED lighting company LedNed. LedNed was founded in 2004 and is headquartered in Helmond, Netherlands. It has 120 employees across various subsidiaries in 7 countries. LedNed specializes in functional white light LEDs, primarily targeting commercial and industrial replacement of fluorescent tubes and bulbs. LedNed differentiates based on quality of light, energy efficiency, long lifespan, and safety certifications. Major markets include replacing fluorescent tubes in offices up to 8 meters and bulbs/par lamps above 8 meters. Developments in high-power LED technology allow LedNed to provide efficient and high-quality lighting solutions.

Developments Oleg Vladimirovich Losev published in 1927 about light emission of diodes used in radio transmitters. The currently used Light Emitting Diode (LED) is developped in 1962 by Nick Holonyak jr. (General Electric) Although he is generally viewed as the person who invented the LED, as shown other people have published about the same phenomenon.

The human Eye The instrument used to detect visible EM radiation is the human eye . It can detect radiation with wavelengths in the range 380 – 760 nm. The sensors that detect light in the retina are called the rods and cones Rods, are sensitive to luminance levels between 10-6 and 10-2 cd/m2. This is called scotopic vision. Almost no color perception! Cones, become operational at 10-2 and 10 cd/m2, colour differentiation starts to occur, this is called mesopic Vision. Above 10 cd/m2 cones are fully operational, this is called Photopic vision. The last receptor called the photosensitive retinal ganglion cells . The function is a non-image-forming (NIF). They provide a stable representation of ambient light intensity,also playing a major role in synchronizing circadian (bio)rhythms, pupillary control and release of the hormone melatonin (sleep).
Light Combining all of the available knowledge to the specific characteristics of a light emitting diode(LED), has given led-lighting designers en engineers today all the tools within reach to take light into a new era.

Power Factor Definition and calculation AC power flow has the three components: real power (P), measured in watts (W); apparent power (S), measured in volt-amperes (VA); and reactive power (Q), measured in reactive volt-amperes (var). The power factor is defined as: P / S (λ= P/S ) In the case of a perfectly sinusoidal waveform, P, Q and S can be expressed as vectors that form a vector triangle such that: S 2 = P 2 + Q 2 ÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌý If φ is the phase angle between the current and voltage, then the power factor is equal to |cos Φ |, and: P = S . |cos Φ | ÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌý Since the units are consistent, the power factor is by definition a dimensionless number between 0 and 1. When power factor is equal to 0, the energy flow is entirely reactive, and stored energy in the load returns to the source on each cycle. When the power factor is 1, all the energy supplied by the source is consumed by the load. Power factors are usually stated as "leading" or "lagging" to show the sign of the phase angle.
