VENTURE VLUMA LED LUMINAIRES OFFER HIGHEST EFFICACY

V

enture Lighting Europe has just introduced a brand new range of VLUMA luminaires, designed to deliver significantly higher performance levels using the latest in LED technology. As the top LED brand in the Venture Lighting range, VLUMA luminaires maximise energy savings and efficiency to give higher lumen output from lower system power consumption. The VLUMA high quality lighting solution from Venture is available across a number of significant luminaires in the company’s range from interior to exterior lighting. For office ceiling lighting, the VLUMA Edge Lit LED panels come in two versions with a power rating of 30W producing some 3000 lumens. Measuring 595mm², they can be recessed or surface mounted and are available with an emergency lighting pack. For the warehouse and industrial market, Venture offers the VLUMA Midibay Elite and the VLUMA LED Highbays. Available in 4 wattages of 109W, 144W,

180W and 254W, the LED Midibays have a colour temperature of 5000K and produce up to 29,000 lumens for an efficient energy saving lighting solution. The Midibays can be specified with narrow distribution or coated diffusers, with high or low level sensors, for mounting on trunking and can be DALI dimmable. Their counterparts, the VLUMA LED Highbays come in 3 wattages of 90W, 150W and 195W. The luminaires produce up to 23,000 lumens at a colour temperature of 4000/5000K and a beam angle of 120°. They are rated IP65 and can be specified with either reflectors or refractors. The VLUMA LED Edge Lit Panels, Midibay and Highbay luminaires all have a long rated life of 50,000 hours. Completing the VLUMA range are two versions of Venture’s successful Westminster LED street lights. These LED modules are designed to be retrofitted into almost any existing street lighting luminaire as a highly energy efficient solution. Achieving L80, B5 rating of 30,000 hours, there are both 3 and 4 way LED versions with a range of lumen outputs up

to 12,000 lumens and with efficacies up to 127 lumens per watt. This retrofit ‘plug and play’ solution can be fitted in the time it takes to clean and change a lamp and has a typical return on investment of under 3 years and comes with a 12 year warranty. Further information on the new VLUMA luminaires is available from Venture Lighting Europe on 01923-692600, by emailing: info@venturelighting.co.uk or by visiting the company’s website at www.venturelightingeurope.com

New Fläkt Woods guide set to improve smoke control in enclosed car parks

F

läkt Woods, a leading manufacturer of ventilation and air movement technology, has published a guide on how to calculate the effect of jet fans on air and smoke flow rates in enclosed car parks. Entitled ‘A Practical Guide to Smoke Control for Enclosed Car Parks’, the technical white paper aims to help designers draw up the correct jet fan solution so that in the event of a fire, smoke can be efficiently removed, rather than accumulating in or spreading to other parts of a car park. The guide’s author, James Allen, senior fire safety and CFD design engineer at Fläkt Woods, explained: “Many enclosed car parks throughout the world employ jet fans to help clear smoke in the event of a fire with good effect. However, current practice relies heavily on air change rates when designing such systems. Although this approach goes some way in assisting designers to meet the minimum

ventilation requirements in car parks, it doesn’t provide all the answers to ensure that a proposed jet fan system will not cause smoke to spread.” The white paper pulls together existing academic research and sets out formulae for how to calculate the rate of air flow according to the type and quantity of jet fans used, smoke flow rate from the fire origin, and how quickly the combination of smoke and air moves when pushed by jet fans. These calculations take into account the size of a fire to determine the extraction rate required at an exhaust point for removing smoke, and can be used in conjunction with CFD modelling. The guide also outlines the steps to consider when designing smoke control solutions. “Currently, no single definitive guide exists to show how to calculate air and smoke flow rates when jet fans are in operation,” James Allen added. “As a company at the forefront of developing ventilation solutions for fire safety, we want

to plug this knowledge gap and provide a foundation for further work and research to be carried out. This will in turn improve the design process and help designers to more accurately identify how much ventilation plant space a car park needs.” Designers can download the ‘Practical Guide to Smoke Control for Enclosed Car Parks’ document free of charge from Fläkt Woods’ website: www.flaktwoods.co.uk/ about-us/media/news/technical-paper/. Fläkt Woods develops, manufactures and distributes ventilation and air climate products, as well as system solutions, for commercial and industrial applications. Its fire safety solutions include fire compartmentation, smoke extraction, pressurisation and car park systems.
