Reflective surfaces for lighting

vega, the highest luminous reflection

Product of the ALMECO GROUP’s exclusive PVD technology, vega represents the new frontier of high-reflectance aluminium.
Developed in the Bernburg factory in Germany, vega significantly improves the reflectors’ optical performance and increases their efficiency by 20% compared to the already high levels of anodised aluminium, thanks to its extraordinary reflectance. vega combines the proven quality of aluminium anodising processes with the most advanced technology of vacuum coating, known as PVD (Physical Vapour Deposition).

optimised for outdoor

The PVD vacuum deposition guarantees a minimum reflectance of 95% to this product, whose finishes range from glossy to diffusing. Isotropic and anisotropic surfaces are also available to meet different light distribution needs.

no compromise in aesthetic and reflection

We recommend vega98 for projects in which energy saving and efficiency come first. Thanks to a variety of patterns and finishes ranging from gloss to diffuse, vega98 guarantees a lighting reflectance of at least 98% with both isotropic and anisotropic distribution.

surfaces for curing, medical and sanitization application

Almeco developed three different types of vega®UV surfaces. These surfaces offer an improved performance compared to anodized materials or other typical reflective surfaces in applications using UV sources.

vega®UV is widely used in curing processes, where the energetic UV radiation is used to initiate photochemical reactions. Several types of inks, coatings and adhesives contain special additives that cause polymerization when exposed to ultraviolet light. The high reflectance of vega®UV can help improve the efficiency of these processes.

Additionally, each vega®UV version has its own specific field of application:

  • vega®UV-A is suitable for suntan lamps, in forensic applications and in the evaluation of gems and art pieces. Many insects can see near UV, so insect traps use these wavelengths to attract them..

  • vega®UV-B finds application in the medical field, for example in light sources for the treatment of psoriasis and other skin conditions 

  • vega®UV-C accelerates the sanitizing action of UV rays. Have a look at the dedicated section here below.

accellerate the sanitizing power of UV rays

vega®UV-C is the high-reflective aluminium surface designed specifically to increase the effectiveness of the sanitizing power of modern UV-C light disinfection systems.

vega®UV-C aluminium surface is produced by Almeco applying nanometric layers through PVD technology (Physical Vapor Deposition). The layers composition is optimized to maximize the reflection in the UV-C region of wavelengths (between 200nm and 280nm).
Thanks to a reflection over 91% it is possible to enhance the sanitizing power of this innovative systems and to reduce the exposure time.

vega®UV-C reflective aluminum surface can be used both as a covering for the internal walls of medical equipment and as shaped reflective optics.

Almeco’s optical engineers are able to support you in the development and production of reflectors to control the electromagnetic distribution by focusing or spreading UV-C light according to your needs and spefications.

enhanced efficacy for horticulture

vega greeN is the improved material for horticultural applications, specifically for HPS (high pressure sodium) lamps.
Since the plant absorption is focused in the red range of the visible spectrum and the sodium lamps has the maximum emission in the same range, we increased the total reflection of the vega95 from orange to red and far red range of the spectrum to enhance the efficiency .
The new vega greeN gives up to more 4% of efficacy if compared to standard 95% TR materials.

optimised solution for LEDs in green houses and horticultural applications

vegagreenLED improves the efficiency of LED reflectors for greenhouse applications by introducing the high performance of an improved silver-based coating, if compared to the vega98 standard, which increases the reflectors’ resistance in hot-humid environments.
Thanks to the maximum uniformity of reflectance in the entire visible spectrum (380-780 nm), vega greenLED is designed for all LED sources and for crops requiring different light wavelengths.

the highest reflection for LED sources

vegaLED represents a real contribution to improving the performance of the LED luminaires. Thanks to its extremely high total reflectance values (> 98%), it creates a more controlled distribution of light and improves the reflectors’ efficiency.
In particular, vegaLED98 guarantees 15% more light for each reflection than metallised plastic and ensures a uniform reflectance of the entire visible spectrum.
The PVD aluminium vegaLED is available in a wide range of surface finishes and therefore offers infinite combinations depending on the design of the reflector and the type of lighting.

combine high reflection and formability

Made with pre-anodised aluminium coated with PVD process and subjected to a particular process which gives the material its specific ductility, vegaform Evolution retains high values ​​of total reflectance even after deep-drawing process.
These values ​​are far superior to those of the aluminium subjected to static anodization, providing for particularly performing reflectors.
PVD aluminium vegaform evolution is particularly suitable for street lighting applications, exteriors and reflectors for specific indoor environments.

your daylighting surfaces

vega SP is a special high reflectance PVD aluminium used for systems that control natural light in closed environments to improve visual and thermal comfort.
These shiny surfaces are characterized above all by a very high total reflectance, equal to 98.5% of the visible spectrum, which increases the efficiency of the system. They also have very low losses due to multiple reflections, an aspect that can be particularly appreciated in light pipes. Moreover, they are characterized by a high uniformity of the visible spectrum and an excellent colour rendering, which gives better visual comfort.

metal core for your CoB

Specifically designed to cover PCB supports, vegaLED on BOARD has an extremely high total reflectance (over 98%) over the entire LED emission spectrum thanks to the PVD treatment to which the material is subjected and it increases the performance of the source compared to a PCB in silver plated copper.
This feature is combined with high spectral uniformity and high optical performance, ensuring a homogeneous source yield.
Furthermore, the PVD aluminium vegaLED on BOARD dissipates the heat generated by the led behind the PCB, ensuring a longer life to the source.

pre-anodised aluminium

reflective surfaces

Versatile, elastic and resistant, the pre-anodised aluminium offers an excellent combination of high reflectance and durability in a vast choice of finishes ranging from highly specular surfaces to the most diffuse ones.
The anodizing process gives aluminium a total reflectance that varies from 80% to 87%, depending on the alloy, processing and finishing.
It has its widest field of application in the lighting technology, with products ranging from reflectors for fluorescent sources to louvers and projectors.
