Nyheter

En virkelig god nyhet! Vi har solgt, igangsatt og programmert systemer fra både Lutron Electronics og Pharos Architectural Controls Ltd i over 15 år. Vi har mange ganger integrert dem på ulike smarte måter, for eksempel for å kunne styre en pikselinstallasjon i en resepsjon eller et pauserom fra et Lutron-system som brukes av hele bygningen eller kontoret. Det har alltid innebåret en del fikling. Nå har de to endelig funnet hverandre, og det finnes en standardisert integrasjon mellom de to systemene som vil gjøre det enkelt å bruke DALI når det er hensiktsmessig og DMX når det er hensiktsmessig, uten at brukeren trenger flere grensesnitt.

Idéen om å arrangere en minimesse med fokus på nytenkning og bærekraftig belysning i Bergen føltes først som en overveldende oppgave. Vi visste at det var stor interesse blant lokale aktører, men å ordne lokale, transportere prøver og overbevise produsenter om å reise til Sør-Norge er en stor utfordring. Men så heldige vi var at vi gjorde det - det ble en helt fantastisk dag med mange interessante diskusjoner om lys og belysning. I tillegg til at vi for første gang viste Fluxwerx Illumination unike produkter i Norge, hadde vi også besøk av alphaLED, lumenpulse og unonovesette® som bidro til et komplett utvalg for belysning både til innendørs og utendørs bruk. Takk til Ole Bull Hotel & Apartments for hjelp med lokaler og service.

Endelig skjer det! Vi lanserer nå Fluxwerx Illumination sine flere ganger prisbelønte, patenterte og virkelig unike armaturer på det skandinaviske markedet. Vårt team har fått grundig opplæring og lært mye om hvordan man oppnår jevn lysfordeling med minimal blending ved hjelp av anidolisk optikk. Unik design og høyeste energieffektivitet følger med. Genialt enkelt sagt. Ønsker du å vite mer om hvordan du kan bruke teknologien i ditt prosjekt? Vi har produktprøver på plass, så ta kontakt med oss for en visning.

Takk til LMPG Inc. for all støtte.

I hjertet av Bergen ligger Kode Museum som i 200 år har vært hjemmet for mesterverk innen musikk, kunst, kunsthåndverk og design. Med sin lange relasjon til museet ble Callum Innes - den verdenskjente abstrakte kunstneren - invitert til å skape en permanent utstilling av lys som gjenspeiler den subtile fargeblandingen som finnes i hans malerier. I samarbeid med Kevan Shaw Lighting Design skapte de to en unik anvendelse av fasadebelysning som dynamisk sykler gjennom 60 unike "malerier" ved hjelp av farget lys. Utstillingen åpnet den 10. april 2024 samtidig med Innes' utstilling med tittelen "Cadmium Orange Red Violet Lamp Black" og er tilgjengelig for alle som besøker Bergen.

I takt med att LED-er har utvecklats som lyskilde og vi kan skape høye lysfluks fra små lyskilder, har optikken vokst fram som et viktig område for å temme lyset og skape armaturer som med stor presisjon kan plassere riktig lysmengde på riktig sted. Lumenpulse er en produsent som tidlig forsto viktigheten av optikk. En årsak til at selskapet ble startet var at grunnleggerne savnet utendørsarmaturer med god optikk, og de har siden lenge hatt et dedikert team som utvikler selskapets optiske løsninger. Vi har intervjuet Dave Grassi, som er ansvarlig for det optiske teamet i Montreal, om hvorfor optikk er så viktig og hvordan de arbeider for å skape fremtidens optiske løsninger. 

Would you mind introducing yourself and your team?

My name is David Grassi, I’m the Optical Engineering Manager at Lumenpulse, I have been at Lumenpulse for over 10 years and have been designing optical systems for LED applications for the past 14 years. At Lumenpulse, we have a team of 3 Optical designers, each dedicated and experienced in their segment (Lumenpulse Outdoor, Site and Area, and Point source). Their names are Isabelle Rivard, Caroline Donkin, and Gabrielle Grondin, each of them has also been working at Lumenpulse for over 10 years.

How common is it that lighting manufacturers have a dedicated team for this? Why does Lumenpulse find it valuable?

Many lighting manufacturers will have at least one employee that is specialized in evaluating optical options found “off-the-shelf” and performing photometric testing, but having a dedicated team for optical design is indeed rare. By having this capability in house, we are able to design optical solutions and deliver truly best in class optical performances, ones that can’t be easily matched simply by combining off-the-shelf solutions. Central to our company’s DNA is customization of our product; we design all of our standard products with the intent that they can be customized further than any product on the market in terms of possible optical distributions and spectral power distributions.

Can you describe the process you use to evaluate and select optics for your products? How often are these re-evaluated?

For any new products, we first evaluate the market need and review what’s currently considered “best in class”; we evaluate pretty much every option, the CCT offerings, the CRI, the outputs, the beam angles, and the intensity. For the beam distributions themselves, there is a lot more that goes into this than just hitting a certain beam angle number. The delivered intensity is calculated and optimized to ensure that we are efficiently directing all of the light within the desired distribution, this mitigates glare and stray light and ensures that you will get the highest light levels for your selected configuration. The shape of the distribution is critical as well, for narrow beams, we want to get every last photon within the beam angle to maximize the possible throw. For grazing distributions, we want to ensure that we are doing everything we can to mitigate shadows between fixtures, to allow for the widest possible spacing between fixtures to reduce project costs. For floodlighting and general illumination, we want to ensure efficient delivered output within the distribution but want to ensure that this doesn’t lead to scalloping in the application. For site and area lighting, we want to ensure the furthest possible spacing between luminaires while maximizing the average illuminance on the roadway and minimizing backlight. We are constantly re-evaluating the performance of all of our products to see where we can continue to improve and innovate.

Now that LEDs are so efficient, raw output no longer seems to the main priority. What are priorities you have when designing optics for Lumenpulse fittings?

LED products have been bright enough to be used in almost every application for years now, the efficiency of LEDs continues to improve every year, but this mostly translates into more and more output which is directly contributing to the continually increasing light pollution of our planet. Our priorities have been to focus more on delivering the right amount of light directly to where it’s needed. We design our optics to ensure a very wide range of distributions to cover all applications and we specifically design these distributions to make sure that we don’t have any gaps in the offering. If you take our Lumenbeam family for example, when you start with our narrowest beam angle and then go to the next wider option, the intensity will drop in half, this will continue across the entire range. The same goes for output as well, the Lumenbeam and Lumenquad family is the largest family of projects on the market today, going from as low as 15W up to 200W. This ensures that you should be able to find the right distribution for your application, one that delivers the appropriate amount of light in the best distribution possible to help designers realize their vision. Just as critical as the performance metrics is the quality of light within each distribution in every product. When we talk about quality of light, this is also something that can be quantified. When we talk about quality of light and color consistency, this is often described in terms of steps. We see this a lot in our industry, that a fixture may be binned to 2 steps or even 1x2 steps, but this refers to the overall average color point of a luminaire being within a certain number of steps relative to the luminaire next to it. However, when we talk about a typical bare LED, there may be as many as 30 steps of color difference between the narrow angle light and the high angle light emitted from the LED. This is a function of modern LED manufacturing. When we add optics into the system, we are essentially imaging the LED, which would project this color difference into the beam itself, so it’s our job as optical designers to correct for poor color over angle. We want to ensure that when we say our luminaires are binned to within 2 steps, we don’t just mean that the average color point of Fixture A is within 2 steps of Fixture B, but that within a single fixture, there is no visible color difference in the beam nor field. We do a lot of work in the design and validation process to ensure that the end distribution is not just best in class performance in terms of output and delivered intensity, but that the quality of light meets the expectations of the market as well.

Any tips for us folks out in the field? What should we consider when evaluating a luminaire?

Don’t just consider the spec sheets. Lumenpulse has nearly every single photometric file available on our website, including with accessories, which is a huge differentiator for us. Many projects will use accessories like snoots, visors, honeycomb louvers, and frosted lenses to reduce glare and skyglow, our database of photometric performance allows designers and specifiers to accurately model them in the space, because you can’t just apply a LLF (light loss factor) to accurately represent how performance changes when adding these accessories. All of our performances are validated by 3rd party testing, which is our commitment to integrity. Having this information is a requirement for a lot of high profile projects, and we want to make sure that our partners can feel confident that what we say and what we show is backed up by hard data.

Any exciting news you want to share?

Keep an eye on our website, we launched the brand new Lumenfacade Max this past fall, which showcases our in-house optical design expertise. We have a LOT of new products launching this year, with brand new and never before seen optical designs. We are really pushing the boundaries of performance across all of our products!
