The British producer of lettuce and herbs puts on lighting LED crops.


The Madestein UK company was founded in 1982 and introduced many innovations to the British market, including curly leaves lettuce at the end of the 1980s and a mix of mixed salads in 2001. Currently, they focus on the production of greenhouse lettuce and fresh basil throughout the year. In addition to traditional growing methods, Madestein UK uses sustainable cultivation methods, such as the Deep Flow hydroponic system, which uses water efficiently and minimizes the risk of groundwater contamination.

– We see a great demand for British lettuce and herbs, so we were looking for ways to increase our productivity. We were impressed by what we saw when visiting breeders in the Netherlands and Finland who use LEDs for growing lettuce. Our goal is to use LED lights to improve the quality, reduce the impact of adverse weather conditions and improve the durability of our products – says Jonathan Zwinkels from Madestein UK.

How does LED lighting work?

LED diode. How does LED lighting work?

The operation of LED lighting is based on electroluminescence, which is the result of a combination of electrons and holes in the P-N semiconductor connectors found in LED diodes.

Semiconductor is a crystal that is made of two layers – the N layer contains electrons (negative charge) while the P layer contains so-called holes (positive charge). When the current is supplied to the semiconductor, the electrons from the N layer jump to the P layer and during this jump, the energy separated out in the form of radiation – that is, simply light – is released. In contrast to incandescent bulbs and so-called energy-saving fluorescent lamps, there is no energy loss for heat and no harmful substances for the environment. In addition, LED bulbs are 100% biodegradable.

 

The color of light in LED lighting depends on the type of material from which the semiconductor is made and on the distance the electrons from the N to P layer have to jump over.
Unlike other light sources that need special filters for this, LEDs produce light instantly in a specific color, making it intense and saturated.

Why LED Lighting?

The best and shortest answer is in a few words: ECONOMY, STYLISTICS, ENERGY SAVING, LIFE, ECOLOGY and SAFETY.


First, ECONOMY, because LED technology is the most financially effective source of light. In practice, this is a reduction in electricity bills by up to several dozen percent. Saving is not everything, it also counts …

 

… STYLISTICS, because each of us wants to surround ourselves with aesthetic objects especially at home and at work. LED lighting gives unique, unprecedented possibilities of arrangement. In addition, LED lighting offers a wide range of colors, so we can get the mapping of natural solar lighting. LED bulbs are not only effective, but also effective.

 

Returning to practical reasons, you can not forget ENERGY SAVINGS. Thanks to LED diodes, you can use up to 90% less energy while maintaining current light parameters. In addition, in contrast to the so-called energy-saving fluorescent lamps, LED lighting shines with full power immediately after switching on. This is not only important for the comfort of use, but also from the point of view of energy saving. LED bulbs do not consume additional energy for warming up.

 

A distinctly perceptible feature is LIFE – incomparably greater than in the case of ordinary incandescent bulbs and even ‘energy-efficient’ fluorescent lamps. LED lighting shines in the same strong light stream up to 50000h without losing its efficiency. Simply put, you would exchange 30 ordinary incandescent bulbs and 6 ‘energy-saving’ compact fluorescent lamps, and at the same time only one LED bulb. What’s more – frequent switching on and off does not shorten the life of the LED, as is the case with other types of light bulbs.

 

ECOLOGY is not only a matter of trends and mentality. It also affects the environment and our health. In contrast to the so-called energy-saving lamps LED bulbs do not contain mercury or other substances hazardous to the environment and our environment. In addition, they are 100% biodegradable.

 

Finally, SAINT. Products using LED technology are much more resistant to shocks and vibrations, which in the traditional lighting cause the incandescent filaments or cracking fluorescent lamp housings. Thanks to their unique properties, LED bulbs do not heat up. The use of LED lighting therefore minimizes the risk of fire or burns to your child.

 

 

led tube light

Replacing gas lamps for LED tubes.

LED tube light Replacement of conventional fluorescent lamps with fluorescent lamps with LED diodes.

LED tube light. LED fluorescent lamps, unlike gas fluorescent lamps, do not need ignition systems. The use of such additives results from the fact that in a traditional fluorescent lamp there is gas and it must be heated to the right temperature, and in the case of LED fluorescent lamps there is no need. The LED tube should be connected directly to 230V in the extreme poles of the fluorescent lamp.

In LED tubes we get 95% power after switching on, but after the diode warms up, the efficiency increases to 100%.

  • Where will the bar be placed and will it be used to illuminate the workplace, ambient light or accent lighting?

  • LED strips should be installed on an even, clean and dry surface.

  • Different types of light are produced by changing the size, number and color of the LEDs on the strip.

  • The use of integrated LED strips inside or outside in dry or wet areas, which are determined by the IP rating of the tape (eg standard (IP20) or with silicone coating (IP65)).

  • Do you need to hide (if necessary) the belt, driver and wires?

  • How will the bar be turned on and off? Will it be part of your lighting circuit or controlled by a separate switch?

  • The final lighting effect will depend on many factors, including;

  • The size of the LEDs, the number of LEDs per meter, the angle and position of the strip, the texture of the color, distance and reflectivity of the surface and distance of the observer from the belt

  • You can evaluate the degree of lighting of the LED strip, installing it on a working tape, which can be removed, for example masking tape, and then safely powering it, see the light beam, pattern and angle before you finally attach the strap.The integrated LED strips are manufactured and tested to the highest standards to ensure uniform color and light quality over the entire length of the strap.LED Strips offer

What is the CRI indicator?

CRI lighting. What is the CRI indicator.

Who knows what the CRI indicator is?

When you look at bulbs or any kind of lamp, you often notice how many products have the number “CRI”, known as “Color rendering index”.

But what is “CRI” and how does its rating affect our decision when buying lighting?

CRI (Color Rendering Index) is a standard measurement of the source’s ability to reveal the colors of objects compared to a natural light source.

The highest possible CRI is 100. It is the same color as natural daylight, which is often found in incandescent / halogen bulbs.

The color of the light is defined as the correlated color temperature (CC9) and is measured in Kelvin (K). Warmer / yellow bulbs = 3500k, and cooler / more blue bulbs = 6500k.

The picture shows a comparison for CRI 75 vs 95

led color

Warm white or Cool white?

LED color. Warm white or Cool white?

LED color. Color temperature is a characteristic of visible light that has important applications in lighting. In practice, color temperature is meaningful only for light sources that do in fact correspond somewhat closely to the radiation of some black body, i.e., those on a line from reddish/orange via yellow and more or less white to blueish white. Color temperature is expressed in kelvins, using the symbol K, a unit of measure for absolute temperature.Color temperatures over 5000 K are called “cool colors” (bluish white), while lower color temperatures (2700–3000 K) are called “warm colors” (yellowish white through red).

Kelvins

If you like the traditional yellowish colour of a conventional lamp then warm white around (2700-3000K ) would be the ideal choice, this is the most popular choice for homes. If you want a modern, clean look, you may prefer the cleaner, brighter feel of a cool white lamp (4000K+). Cool white light contains more blue light and looks brighter

Color temperature comparison of common electric lamps

ledcolortemp

The following standard colour scheme is recommended:

Warm to Warm white – living room, bedroom, hallway

White to Cool white – kitchen, study, bathroom, cupboard, office, retail

Daylight – Commercial, retail, art studios

How do I know which one I am buying ?

All Integral retail packs have a clear icon and colour temperature indicated on the packaging. In addition, each lamp will have the colour temperature printed on the base e.g. ” 3000K”.
