This is a method of controlling and regulating electric current or voltage signal of constant amplitude and frequency by changing the value of the current or voltage fed to the load. The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast rate. The longer the switch is on compared to the off periods, the higher the total power supplied to the load.

The flicker free label can be applied to a product on the basis of three separate measurements taken using GL Spectis 1.0 + flicker equipment supplied by the GL OPTIC brand.

Artificial lighting is also not neutral to humans. The colour of artificial light can affect the mood, level of concentration and psyche of a person. The colour of the light is expressed by the colour temperature in kelvins (K). It is commonly believed that white colour light with a warm tint (below 3300 kelvins) gives a sense of comfort and relaxation. The neutral colour (4000 kelvins) works well in offices as it boosts up our concentration. On the other hand, the colour temperature of approximately 6000 – 6500 kelvins is considered to be comparable to the daylight (on a cloudless day).

The testing methodology included in the standard specifies both electrical and photometric measurements carried out under specific conditions and parameters. At the LED line® Light Research and Measurement Center photometric measurements are performed in Ulbricht integrating sphere in accordance with the LM79-08 standards, which requires measurements of the total flux of light, CRI color characteristics, CCT, chromaticity coordinates, electrical parameters and light efficiency. During the measurements it is necessary to ensure the tests are performed in an ambient temperature of 25°C with a tolerance of +/- 1°C and to limit the air movement during the measurements. The AC power supply must provide a harmonic distortion limit of 3%. In addition, measurements should start after the luminaire has been warmed up for 30 minutes. LM79-08 standard also refers to measurements in gonio spectrometer, where additional measurement of light distribution is performed.

Percent Flicker – A relative measure of the cyclic variation in the amplitude of a light in one on/off cycle (index range: 0%-100%). 100% flicker would indicate that, at some point in the cycle, there is no illumination provided at all. In a properly stabilised light source, the Percent Flicker parameter will be 0%.

Research has shown that flickering has an adverse effect on human well-being and causes tearing and eye fatigue. Currently, two flicker parameters have been developed by the IES. “Flicker Percent” which is featured by relative measure of cyclic variation in light amplitude and “Flicker Index” which includes the percentage of flicker, the shape of the waveform and the work cycle, which refers to the percentage of time in a single cycle.

A separate LM80-08 – standard – is used for LED light sources without built-in power supplies. According to its requirements, the luminous flux and chromaticity coordinates must be measured at three levels where the temperature of LED/housing connection reaches: 55°C, 85°C, and the third temperature value is specified by the LED manufacturer. Measurements are made for a period of min. 6000 hours with intervals of no more than 1000 hours. The results of the measurements allow to observe how the diode changes its light parameters during the test. Please note that the LM80-08 standard only provides a method for testing the maintenance of the luminous flux.

This is the electromagnetic spectrum with wavelength from 100nm to 400nm, shorter than that of visible light but longer than X-rays. By reason of the extent (scale) or effects of the UV presence, the UV is divided into the following:

LEDs do not emit UV radiation so the technology is safe not only for living organisms but also for various elements, such as paints, colorful plastics, museum exhibits.

This is a lighting concept in which the human and their needs are put at the centre of lighting design. All human beings have evolved with natural light so the composition of the sunlight spectrum is the best model on which to base our lighting design. Lighting, according to the HCL concept, imitates the parameters of natural light and adapts them to the daily needs of a human. That means that light designed according to HCL should give us energy to work in the morning and prepare us for a period of relaxation and sleep in the evening.

This is a digital interface for lighting control devices, in particular – this is a dedicated solution for dynamic lighting. The system can be addressed with 512 channels in one signal line with up to 32 devices. The DMX technical standards are set out by USITT organisation and has become a widely used system within the music/movie stage industry or for the professional illumination of various buildings. Signal receivers are controlled by a shielded two-wire cable with an impedance of 110 ohm. The control is performed with the use of DMX standard controllers.

These are defined as shown in the figure below. If the luminaire is rotationally symmetrical, the light distribution is given in one plane C only. However, in the case of an unsymmetrical luminaire, the luminous values are given in planes C in angles of 30° or even 15°. The light distribution diagram provides basic information about the shape of the luminaire’s light distribution.

These represent the light distribution produced by a luminaire or light source after measuring its light intensity in different directions. A curve (diagram) of the luminaire’s light intensity can be created after converting the results into values, which would be obtained using light sources with a total luminous flux of 1000lm.

All MR16 and MR11 LED Line ® brand sources have switched -mode power supplies incorporated. They provide stabilization of LED working points, significantly increasing the life of the lamp. They also provide a constant level of luminous flux within the whole range of supply voltage. What is a great advantage of this type of source, is also the reason why we cannot use PWM type power supply.

Material used in the construction of LED luminaires. It has an excellent mechanical properties and is particu-larly resistant to mechanical impact. Compressive strength is similar to aluminium. Visible light transmission is at 90%.

Measured in the range between 0 and 100, this is a quantitative measure of the ability of a light source to reveal the colours of various objects faithfully in comparison with an ideal or natural light source. Numerically, the highest possible CRI value is 100 and would only be given to a source identical to standardised daylight (sunlight with a colour temperature of 6670K). The higher the CRI value, the better the colours of illuminated object/surface are revealed. Ra is the average value of 8 colour samples, whereas CRI uses a palette of 15 colours (R1 – R15) and tends to be more accurate.

LED line® offers a wide range of lighting solutions out of which we can choose the right  color temperature to suit our needs. LED line® lamps offer a wide range of colour temperatures from 2700K to 6500K.

The power factor of an AC electrical power system is defined as the ratio of the active power absorbed by the load to the apparent power flowing in the circuit. In simple terms, it determines what part of the energy taken from the electrical network will be used effectively by the device. A power factor of less than one indicates that the power was consumed from the electrical network but not used (reactive power). This causes undesirable heat emission.

Flickering can be defined as: the perception of visual instability/unsteadiness caused by lighting variations in brightness. The Illuminating Engineering Society (IES) developed two flicker metrics.

We work with respected installation companies operating throughout Poland. Our specialists train employees in the field of industrial and commercial lighting installation.

A batch file dedicated for the design software (e.g. Dialux, Relux) – these files are necessary for the creation of lighting design.  It describes the intensity of light in the individual points of a sphere grid. These files also contain information on the geometry of the light output to the outside of a luminaire. The files are featured by the *.ies extension defined by IESNA LM-63-2001 and *.ldt defined as EULUMDAT.

Flicker Index – This includes the flicker percentage and two other variables: the shape of light intensity waveform or output light distribution curve. In another words, it is a measure of the cyclic variation taking into account the shape of the waveform.. The lower the flicker percentage and flicker rate, the better the stability of a light source.

This is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through, is emitted from, or is reflected from a particular area, and falls within a given solid angle. The SI unit of luminance is ‘candela per square metre’ (cd/m2).

As commonly accepted, LED product lasts four times as long as a compact fluorescent lamp and 25 times as long as a conventional incandescent lamp that generates the same amount of light.

The IK rating is an international numeric classification to indicate the degrees of protec-tion provided by light fixtures against external mechanical impacts. It provides a means of specifying the capacity of a fixture (luminaire) to protect its parts (components) from external impacts. The range of protection is measured on the scale from 00 (no protection) up to 10 (impact resistance against 20J). The higher the numerical value of the IK parameter, the greater the mechanical protection of the given device.

Artificial light systems which also use daylight are striving to balance the amount of electrical light needed for appropriate area illumination to reduce the power consumption. It can be done with light control techniques that can dim or switch the electric light in response to changing amount of daylight.

This type of power supply is a much more sophisticated structure. Thanks to the application of new technologies, we can obtain the advantages of such a solution. The main advantages include:

In AC systems, this is the part of the power that the receiver takes from the source and changes to effective energy or heat. In DC systems, all power is active power. The SI unit of active power is watt (W)

The use of professional LED lighting is means predominantly energy-costs saving, comfort of use and protection of the environment. Below is a short list of advantages of using LED lighting:

NOTE: In order to ensure durability of the LED lighting system, it is necessary to choose the wattage of the power supply which is at least 10% higher than the required power for the given section of LED strip. This guarantees that the PSU will not be overloaded, which translates into its durability and reliability.

Expressed in Kelvins [K], it is a measure of the colour impression of a given light source. Lower [K] values are perceived by the human eye as warmer colours.

Luminous efficacy is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power, measured in lumens per watt (lm/W) in the International System of Units (SI).

An increase in power in watts translates into a slight decrease in efficiency. A 3W LED light source will emit slightly less light than three 1W light sources. In general, the characteristics of components (e.g. optics, heat sink, chips, LED modules and driver) have a greater impact on the light output than the wattage output.

50,000 hours means 5.7 years lifespan on the assumption that the light is switched on 24 hours a day; 7.6 years if the light is switched on 18 hours a day and 11.4 years if the source is switched on 12 hours a day.

Scientific research has shown that a person should spend several hours a day in light of 4000 lux in order for the body to function properly. If we are exposed to insufficient amount of light we can experience a significant decrease in concentration and become tired and feel a sense of sleepiness. What’s more, a person may fall into depressive state in the longer absence of exposure to natural light.

Apparent power is the product (multiplication) of the RMS (root mean square) values of the current and voltage in AC circuits.

In summary, it should be remembered that the LM79-08 standard applies to complete luminaires and light sources equipped with power supply systems. LM80-08 tests are performed on a single LED or a set of LEDs without power supply systems in order to determine the loss of light flux by using calculations determined in TM21-11 document.

Over and above, the norms make mention of the actual risks caused by both, natural and artificial light. These are inter alia:

The SVM is a method used to quantify the stroboscopic effect visibility in general illumination application. SVM is defined by  measuring  the visibility  threshold  of  light  waveforms  modulated  at  several  frequencies and uses Fourier analysis to convert the wavelength shape of the light intensity. The stroboscopic effect can cause an impression of slowness, stopping or even reversal of the direction of movement of an object, which can lead to various accidents.

This shall not be confused with Luminance. Illuminance is a measure of how much the incident light illuminates the surface: 1m2 (lm/m2), wavelength-weighted by the luminosity function to correlate with human brightness perception. The SI unit is Lux.

In addition to flickering, we distinguish a separate stroboscopic effect, also called SVM (Stroboscopic Visibility Meausure). The SVM is a method used to quantify the stroboscopic effect visibility in general illumination application. SVM is defined by  measuring  the visibility  threshold  of  light  waveforms  modulated  at  several  frequencies and uses Fourier analysis to convert the wavelength shape of the light intensity. The stroboscopic effect can cause an impression of slowness, stopping or even reversal of the direction of movement of an object, which can lead to various accidents. The frequency amplifying the unwanted stroboscopic effect is between 80 Hz and 2kHz. In addition, stroboscopic effects can cause epilepsy, loss of perception and headaches.

The Pst Lm indicator measures the flicker of visible light caused by modulation in the frequency range from 0.3 Hz to 80 Hz.

In alternating current circuits, reactive power is a quantity describing the fluctuations of electric energy between the elements of an electric circuit. This oscillating energy is not converted into usable/effective energy or heat, but is necessary for the functioning of electrical equipment. The energy is taken from the source in one part of the alternating waveform period, stored by the receiver and returned to the source in the other part of the period, which is related to the disappearance of the magnetic field in the receiver. For sinusoidal waveforms, reactive power is defined as the multiplication (product) of induced voltage and current values, and the phase shift angle sinus between voltage and current. The reactive power SI unit is var (var).

The industrial lighting offer has just expanded! We introduce new products in the LED line LINKER family – a new 30W and 40W luminaire in black.

This type of power supply contains semiconductor components in its structure. However, it is still a simple construction. The use of an IC element significantly reduces the size of the entire power supply, and significantly increases the PF factor, as well as the efficiency. An additional advantage of this design is maintaining good output parameters, which in turn increases the life of LEDs. Still, the lamp provides an unacceptable level of strobe effect, which, however, can be reduced by slightly changing the structure, but at the expense of the Power Factor. So, this entails either a stroboscopic effect and good PF, or a stable light without flickering but with a lower phase shift factor. Power supplies of this type are used in low power lamps, where the most important thing is to achieve minimum lamp size.

This means of control is performed without an additional control wire. The user shall simply connect the dimmer in series between one of the mains wires and the receiver (equipment). We must remember about the compatibility of light sources (driver, LED module) with this analog dimmer.

It is a power supply with a very simple structure. However, this is one of its few advantages. Its disadvantages certainly include a very low Power Factor coefficient and very low efficiency. There is also no possibility to modify such a power supply in order to eliminate the stroboscopic effect. Due to the considerable size of the power supply and successively improved eco-design regulations concerning the PF factor, it is used in low-power lamps, usually up to 3W.

Converting the UGR impact into quantifiable numerical values would be extremely time-consuming, but already at this stage it is possible to answer the above question in the affirmative manner. Yes, high-performance lighting increases employees’ productivity. That is why it is worth choosing luminaires with a low glare rating for the professional illumination of offices.

This is an international standard set up by the International Electrotechnical Commission defining the protective-earth connection requirements for electronic devices. In other words, the protection class defines the means that should be adopted to ensure protection against electric shock. However, it is not in any extent a measure relating to the safety of the given product. The classification is set out in the PN-EN 61140: 2005 regulations. In summary, there are four classes of protection: 0, I, II, III. Protection classes are illustrated with symbols, except for protection class 0, which has no symbol and therefore no protective earth connection whatsoever. The symbols are shown in the below picture.

Position of the coordinates on the chromaticity diagram in relation to the Planck curve. The parameter determines the distance from the Planck curve.

Due to the increasing need to save electricity, the use of LED sources has become a necessity. So the long lifetime of LED modules brings both environmental and financial benefits. Due to the need of determining the durability of LED sources, a parameter marked LxBy was created. This parameter indicates the time in hours after which 50% of a population of LEDs parametrically reduced their lumen output, in a gradual way, and provides less than 70% of lumen output compared to the initial (original) luminous flux. A luminous flux lower than the lumen maintenance factor (expressed by Lx value) is called a “parametric failure” because the product produces less light, but remains working. By way of illustration, the life span marked as L70B50 50000h tells us that after a period of 50000 hours, 50% (B50) of a population of LEDs (which a given LED lamp is equipped with) provide up to 70% (L70) of the initial light output. Due to the fact that the temperature has a significant influence on the Lumen Maintenance Factor(Lx) it is necessary to give indication for the ambient temperature at which the life span of LxBy was determined. As the temperature has a significant impact on LxBy’s lumen maintenance factor, the ambient temperature at which LxBy’s shelf life is determined should be given.

This parameter determined based on the light’s intensity in a certain direction. The analysis begins from “angle zero” – in front of the luminaire. We check the luminous intensity levels by increasing the angle and when we observe that the luminous intensity level is twice as low as its maximum, we consider this as the borderline for the beam angle measurements.

Type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. It is used in the production of lampshades and diaphragms in LED fittings. It has three times greater resistance to mechanical damage compared to ordinary glass. Tempered glass has much higher thermal resistance than standard glass and, when broken, the glass crumble into small granular chunks instead of splintering into jagged shards as plate glass.

LED light sources have a longer life span, which reduces their maintenance and replacement costs . Since LED products need to be replaced less often, the user spends less time on buying new lamps and replacing them. LED light sources consume less energy than conventional light sources. Investment pays for itself quite quickly.

This is a system in which by controlling input voltage the user adjusts the output power level of the device. The control voltage is independent of the device power supply voltage. The value of 10V corresponds to 100% of the output power. The value of 1V corresponds to 5-10% of the output power.

When analysing the above hazards, it is becoming  obvious that any sources of light shall be purchased from trusted manufacturers only.

Each of them serves exactly the same purpose – it directly connects the power network to the LED structure and provides it with conditions for correct operation. It also determines the main parameters of the whole lamp. On the power supply depends, among other things, the level of PF coefficient and the stroboscopic effect.

Estimation of LED source durability/degradation is provided by TM21-11, which uses the LM 80-08 test standard. Based on the test, estimation of light flux loss during 36,000 hours (6k) (or longer if the test is longer than minimum) is made. The test result is recorded as e.g. L70, where 70 means that the LED will maintain a luminous flux of 70% of the initial value after a period of 36,000 hours (6k).

Beam angle of a directional light source is another light sources’ parameter which is normally provided by lighting manufacturers.

A significant parameter which is often overlooked by less experienced investors is the quality of illumination emitted by a luminaire – unified glare rating. The lower the UGR, the higher the comfort of people working within the illumination range of the luminaire. It is obvious that the greater the comfort, the higher the productivity of the employees.
