About Veko

We deliver to installers and end users. We do not deliver to individuals.

 

By default, Veko supplies all LED luminaires with a unique replacement warranty of 5 years or 25,000 operational hours. Furthermore, Veko applies a 1-year warranty to batteries of decentralized emergency lighting, and a 2-year warranty to all other products.

In case Veko has installed the lighting, we will check it between 200 operational hours and 1 year after delivery once and repair any defe

cts.

A detailed description of the warranty terms of Veko Lightsystems International can be found in article 17 of our general terms and conditions. For local sales within the UK, article 15 of the general terms and conditions of Veko Lightsystems Ltd is applicable.

In some cases, we can even provide 10 years warranty on LED fixtures. More information about this can be provided upon request. The full guarantee plan can be obtained from Veko.

Products

Yes, both central and local emergency lighting are possible.

Aluminium provides good heat dissipation, increasing the lifespan of our LEDs. It is also very durable in itself and, once installed, does not need to be replaced. The profiles are a one-off purchase, and the luminaires can be replaced individually – a future-proof solution. Our aluminium profiles are made of recycled aluminium.

Definitions

LEDs are Light Emitting Diodes: electronic components that convert electrical energy directly into light through the movement of electrons inside the diode material. LEDs are important because, due to their efficiency and low power consumption, they have become a substitute for most conventional light sources.

The Surface Mounted Device (SMD) LED is 1 LED on a circuit board, which can be in mid-power or low power and is less sensitive to heat generation than a COB (Chips On Board) LED. SMD LEDs are usually mounted on a Printed Service Board (PCB), a circuit board onto which the LEDs are soldered mechanically. When a small number of LEDs with relatively high power are used, the heat distribution on this PCB is unfavourable. It is better to use a mid-power LED in that case, because the heat is then better divided between the LED and the circuit board. The circuit board must consequently also lose heat. This is achieved by placing the PCB on an aluminium profile. High-quality LED lighting products have an aluminium profile on the outside in order for the ambient temperature to cool the lamp. Cheaper variants are equipped with a plastic casing, since plastic is cheaper than aluminium. These products only offer good heat dissipation from the LED to the base plate. If the aluminium does not lose this heat, cooling remains problematic.

More about light

Increasingly, light sources are being expressed in the unit Lumen. Light sources were formerly measured by ‘Wattage’. In traditional lighting, the ratio between Lumen and Watt was equal, and not bound to a brand or kind of lamp. Lumen is the light intensity that a light source emits, and is not visible. The radiation that comes from a lamp until it touches a surface, such as a work floor, is called light intensity, and it is displayed in Candela.
The amount of light reaching the floor (or desk) is measured in Lumen per m2, i.e. Lux (1 Lux = 1 Lumen per m2). The illumination intensity is measured with a Lux meter.
Luminance is the radiation of the work floor to our eyes, the unit is Candela per m2. This is measured with a spectrometer and/or luminance meter.

Light bulbs and halogen lamps are known to lose up to 95% of energy in the form of heat. Many people think that no heat is released with LED lamps, but the opposite is true. LED lamps also generates heat, about 50 to 70% of the energy is converted into heat. In order to ensure the quality and lifespan of the LED, this heat must be discharged via a base plate (PCB) and through an efficient heat conductor such as aluminium. The efficiency of a LED lamp is determined by the extent to which the absorbed power is converted into as much light as possible and as little heat as possible. The more light we get out of a LED lamp, the higher will be the Lumen/Watt ratio. So, a high lm/w ratio LED lamp produces less heat than a lower lm/w LED lamp.
