tm30-icon

TM30

It is a new light measurement system created in 2015 where 99 color samples are taken into account, as opposed to the 8 used by the CRI standard.


This system measures:

  • Color fidelity / RF (Real Feel): similarity to reference light
  • Color gamut: saturation index
  • Shape of the gamut: hue and saturation graph


It is represented in a pie chart, where the black circle is the reference light (sunlight), the red circle represents the light to be measured.


If the red circle is inside the black circle it means that the colors are desaturated.


If the red circle is outside the black it means that the colors are oversaturated.

Chromatic coordinates

Chromatic coordinates allow us to precisely identify the colorimetric characteristics of a light source.

 

The exact position of the coordinate is defined in X and Y within a graph defined at its ends by the basic RGB colors.

 

In the brightest central part are defined the white tones ranging from 1,000ºK (yellowish white) to 20,000ºK (bluish white).

 

The MacAdam ellipses inform us about the level of color variation possible between these axes before the human eye can detect these color changes.

The distance between ellipses is measured in SDCM (Standard Deviation of Color Matching):

 
  • 1 SDCM: No color differences exist.
  • 2-4 SDCM: There is hardly any visible difference.
  • 5 or more SDCM: It is easily perceptible.

kVA in LED lighting

 

The kVA indicates the real energy consumption (W) of our LED system. Being 1000VA equal to 1000W with a power factor (PF) of 1.

 

The kW represents the power of an electrical system, while the kVA indicates its apparent power.

 

If your LED system consumes 1000W with a PF = 0.6, the real power we will pay will be 1400W.

Watt’s Law

Free of electromag. rad.

Electromagnetic radiation is produced by oscillating electric waves which, by creating magnetic fields, affect other electronic equipment in the surrounding area.


The regulations clearly mark the levels that should not be exceeded in order not to affect people.  There are LED products that do not emit radiation and others that do. 


Led solutions can be passive and not emit electromagnetism. It is essential that they do not have coils, which are responsible for creating electrical pulses and pulsating frequencies.  

How electromagnetic radiation affects

Parallel Flex L6

This product emits electromagnetic radiation in compliance with low emission standards.

Parallel M9

This product does not emit electromagnetism, it has no coils or frequency oscillators.

Complies electromagnetic radiation standard

Electromagnetic radiation is a type of variable electromagnetic field, i.e. a combination of oscillating electric and magnetic fields, which propagate through space transporting energy from one place to another.


It is estimated that between 5 and 10% of the population is electrosensitive and among the most frequent symptoms are headaches, insomnia, irritability, depression or increased risk of cancer, according to the World Health Organization (WHO).


An institution of the stature of the Council of Europe recommends in its Resolution 1815 that the ALARA Principle be applied, which advises exposure to these waves to be as low as possible.

How electromagnetic radiation affects

Ecodesign

Ecodesign or eco-design is a methodology that seeks to identify, from the moment a product or service is designed, the environmental impacts that may result from each of the phases of its life cycle, in order to try to reduce them as much as possible and always without impairing the final quality.


This life cycle thus includes different phases such as manufacturing, packaging, transport, distribution, use, repair, recycling and reuse.

Flicker Free!

In general terms, flicker is a visible and repetitive change in light intensity caused mostly by voltage fluctuations.


Flicker-Free technology is the technology that protects our eyesight from eyestrain by counteracting the level of flashing or flickering that many LED luminaires exhibit, whether in lighting, on computer monitors, or on a television screen.

Variable color temperature

White-tunable products allow a luminaire to change its color temperature in the range of 2,700ºK to 6,500ºK.


A dim-to-warm product attempts to reproduce the same type of warm lighting obtained from incandescent sources to promote intimate environments, often used in hospitality and restaurants.

Dimmable

The term dimmable in electricity comes from the word “dimmer” which in English refers to regulator or attenuator of intensity, that is to say that it serves to control the energy in one or several levels with the objective of managing and varying the intensity of the light emitted.


When we talk about dimmable products in the lighting sector, we refer to luminaires that can modify their light intensity.

Chromatic coordinates after 6,000h

Chromatic coordinates allow us to precisely identify the colorimetric characteristics of a light source.

 

The exact position of the coordinate is defined in X and Y within a graph defined at its ends by the basic RGB colors.

 

Over time (thousands of hours), these coordinates shift from their origin causing the LED to emit a color different from the original.

In professional LEDs this color variation is not noticeable to the human eye.

Luminous flux maintenance

The amount of light from any luminaire decreases over time.


The lifetime of an LED has been standardized in the industry as the reduction of its luminous capacity to 70% of the initial output within 50,000 hours. It is also known as L70.


There are products that have better degradation than the standard, reaching L90 (90%) or even more.

Actilum™ Spectrum

CRI

The sun is the most natural light we have and, consequently, it is the standard against which any light source is compared.


The CRI (Color Rendering Index) gives us information about the ability of a light source to faithfully reproduce the colors of an object, in relation to sunlight.


Therefore, the higher the CRI, the more natural and true to life the colors of the illuminated object will appear.

Light beam

The light beam is the set of those rays that share an origin and whose propagation develops without dispersion.


Multiple light rays emerge from the same point and make up a beam of light.

Tp Max.

The maximum temperature that LEDs can reach to work properly is about 40°C and in some cases, 65°C, depending on the manufacturer and model.

 

In the case of luminaires in general, they can reach higher temperatures in the heatsink up to 90°C while their electronics can have a temperature of between 60°C to 80°C.

 

High temperatures are the enemy of LEDs.

Relationship between lumen vs. temperature

Lifespan

The lifespan is the estimated duration that an object can have, correctly fulfilling the function for which it has been created. It is usually calculated in hours of life.

 

For certain technologies, such as LED, there are also other indicators of lifespan such as the point at which the luminous depreciation begins, which depends on:


– Deterioration due to aging.
– Accumulation of dust or dirt on optical parts
– Oxidation of the internal part of the luminaire
– Temperature variations
– Installation failures…

Example of lifespan of an electronic product

In electronic products, their service life depends on the electronic component with the least useful hours.

LED color

LED color temperature is a value that is measured in degrees Kelvin (K) and determines what we consider warm light tones and cool light tones.


When a black body is heated, it radiates a different type of light depending on the temperature, creating that warm or cool light that we understand as color temperature in LED luminaire.


LED lamps can be manufactured with a certain color temperature by combining different chemical compounds.

eficiencia

Efficiency lm/W

Luminous efficiency (lm/w) is the ratio of the luminous flux produced by a light source to the electrical power consumed.

 

The energy lost in transforming electricity into light is transformed into heat.

 

Therefore, the higher the efficiency, the lower the energy wasted as heat and the higher the luminous flux.

 

Efficiency(lm/w)=Luminous flux(lm)/Power consumed(w)

Example of luminous efficacy (lm/W)

Lumen

The lumen (lm) is the International System of Measurement unit for measuring luminous flux, a measure of the luminous power emitted by the source.


There is a concept that is often confused with “lumen” although it does not mean the same thing: it is “lux”, which is used to determine the amount of light projected on a surface.


There is a relationship between the two, since one lux is equal to one lumen per square meter.

Consumption

The amount of energy or power demanded for a given period of time (kilowatt-hour or kWh).

 

The kilowatt-hour (kWh), equivalent to one thousand watt-hours, is generally used for billing household electricity consumption.

 

As of March 1, 2021, the European Union has revised and optimized the energy label by eliminating the categories “A+++, A++ and A+”, so that there is a common scale from A to G for all rescaled products.

 

For lighting products, the following rule is applied to determine their energy rating according to their lm/W efficiency

Energy rating according to consumption in lm/W

etiqueta-energetica-A

≥ 210 lm/W

etiqueta-energetica-B

From 185 to 210 lm/W

etiqueta-energetica-C

From 160 to 185 lm/W

etiqueta-energetica-D

From 135 to 160 lm/W

etiqueta-energetica-E

From  110 to 135 lm/W

etiqueta-energetica-F

From 85 to 110 lm/W

etiqueta-energetica-G

Official EU data

Voltage

Electrical voltage or potential difference (also called voltage) is a physical quantity that quantifies the difference in electrical potential between two points.

 

It can be measured with a voltmeter. Its unit in the International System of Units (SI) is the volt.

voltaje

Power factor

Power factor (PF) in LED lighting

 

In LED technology current drivers are used, these power supplies, in their conversion (AC – DC) generate a phase difference between voltage (V) and current (A) according to their quality.

 

The PF values this phase difference on a scale from 0 to 1, with 1 being the perfect value with no phase difference. The lower the value the higher the energy consumption of the LED system as a whole.

espectro

Spectrum

The electromagnetic spectrum is the energy distribution of all electromagnetic waves.

 

Sunlight is measured in nanometers (nm) with a spectrometer. The maximum visible light for the human eye ranges from 380 nm to 730 nm and perceives the highest luminous flux in the set of green, yellow and amber colors.

Below is ultraviolet (UV) radiation and above is infrared (IR) radiation.

 

Conventional LED light has a high peak in blue and lacks azure and red colors.
