Light Without Shadowing

Image
Optics in the new OSRAM classic bulb-shaped LED lamps ensure uniform light with beam angles of up to 300° The unique optic by OSRAM Whether the light of a lamp is perceived as being pleasant by customers depends on many different factors, for example color temperature and luminous intensity. The distribution of luminous intensity in the so-called far field is also important, meaning where light hits walls, floors or table surfaces, and of special importance in this respect is that light is distributed homogeneously and that no shadowing or linear structures are seen. These tasks are achieved by optics assembled within the LED lamps with classic forms, i.e. pear, candle or drop shapes.  In the past this often presented a problem particularly with clear lamps, because with these lamps such optics can be seen from the outside, meaning that these are not only a functional element but must also be visually attractive. In this respect the optic also ensures that the "technolo

Chelsea and Westminster Hospital upgrades lights with DoH funding

Lux Magazine reports:  Chelsea and Westminster Hospital has upgraded its lighting to LED in an effort to cut energy bills and improve patient and staff wellbeing. The hospital, in Fulham Road, London, provides a range of specialist services for patients as well as general local services. The hospital, built in May 1993, is currently expanding and upgrading its facilities. The trust secured funding from the Department of Health for the upgrade to LED lighting, based on predicted energy savings and CO2 reductions. Thorn was selected to provide a mix of standard, modified and bespoke fixtures. Thorn’s Chalice LED downlights were installed for circulation areas, College LED luminaires in the corridors and Omega LED luminaires in the wards. Bespoke fittings were provided for the atria and staircases at the trust’s request to fit in with the original architecture. To minimise the electrical works and avoid disruption to patient care, existing fixtures were replaced point for poin

Can LEDs give us juicy tomatoes all year round?

Image
Philips has teamed up with a horticultural research centre in Yorkshire to test the effects of different kinds of lights on how tomatoes grow. The tomatoes are being grown under 100 per cent artificial light at Stockbridge Technology Centre (STC). Working with Philips, which has experience of similar projects in the Netherlands as well as an array of LEDs and high-pressure sodium (HPS) lamps, STC hopes to identify the conditions for maximising the year-round yield and quality of the fruit in a controlled environment. To this end, the roof on one of STC’s glasshouses has been raised to a height of 5.5m. Beneath it there are four compartments in which four different lighting regimes are deployed. For the duration of the research, each one uses a different combination of LED and HPS lights installed above the crop and within the crop canopy. The extra height of the LED4Crops facility allows for the multi-tiered production that many believe is necessary to meet the nutrit

Project Hammersmith Apollo, London

Star QUALITY LUX magazine reports. First impressions count at one of London’s top music venues. Robert Bain reports.  The names of London’s major theatres and concert halls have become iconic, and few more so than the Hammersmith Apollo. The Apollo first opened as the Gaumont Palace cinema in 1932, with a huge seating capacity of over 3,000, and lavish front-of-house facilities including a large first floor restaurant. In the 1960s it was renamed the Hammersmith Odeon (a name by which many still know the venue), and became a concert hall. The list of musicians to have graced the stage reads like a who’s who of the past half century of popular music. FADED LUSTRE But like many such venues, the once opulent Apollo has not had the best of care over the years. As its use evolved from swish cinema to sweaty rock n’ roll venue, the Apollo’s lustre faded. Now the Grade II listed building is in the midst of a rebirth. When Kate Bush made her comeback t

How Efficient - LED Lighting

Image
Alan Turvey, Technical Engineer at ELECSA looks at energy efficient lighting and the different options available to contractors installing them. In Kyoto in 2009 an agreement was reached, by the majority of countries who attended the summit, to reduce greenhouse gasses emissions by reducing energy usage. The member states of the European Union agreed a series of dates to work towards. This is being implemented in England and Wales through the Building Regulations via the Approved Documents L1, in Scotland by Section 6: Energy, of the Technical Handbooks and in Northern Ireland by Booklet F: Conservation of Fuel and Power. This article will concentrate on the energy efficient lighting in dwellings, which has been estimated to account for 7% of domestic energy usage. It is worth noting that the Domestic Building Services Compliance Guide applies these regulation requirements in both new build and renovation circumstances. With the production and sale of general purpose

Blue LED inventors awarded Nobel physics prize

Image
This year's Nobel Prize for physics has been awarded to the inventors of the blue LED - the key breakthrough that made LED lighting possible. The prize of eight million Swedish krona (€882,000) went to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura ( pictured at LuxLive last year ) 'for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources'. They join a list of 196 other laureates going back to 1901. The Nobel Prizes aim to recognise developments that have brought 'the greatest benefit to mankind'. The award for the Japanese scientists represents a major endorsement of the significance of the LED lighting revolution, and the technology's potential to make the world a better place. At the time, Akasaki and Amano were working for the University of Nagoya, while Nakamura was working for LED maker Nichia. Nakamura told this morning's press conference, 'It's unbelievable

Ford shifts car and truck plants to LED lighting

Image
More muscle, less energy:  Ford has started its LED factory overhaul at the Dearborn, Mich. plant that makes the new 2015 F-150 pickup truck. Lux Magazine reports: Auto makers are constantly searching for ways to reduce average emissions per vehicle. For Ford Motor Co., that quest has just hit the ceiling.  No it hasn't maxed out its cars' engine and fuel efficiency.  Hopefully it will continue to make strides there. Rather, Ford's latest advance comes in the energy that it spends on producing each vehicle. The $147 billion car and truck manufacturer is replacing the conventional overhead lighting at 18 assembly plants around the globe with $25 million worth of LED fixtures, Ford said  in a press release . It anticipates cutting lighting energy consumption by 70 percent compared to the standard fluorescent and high-intensity discharge lamps, and expects annual savings of around $7 million. It also cited the 15-year life expectancy of the LED (light emitt

LEDS: AN EFFICIENT ALL-ROUNDER

Image
From domestic households and the catering sector to industrial applications – light emitting diodes (LED) are becoming ever more popular, because high quality LEDs in particular from renowned manufacturers such as the lighting expert Osram feature significant benefits compared to standard light sources. They feature good colour rendering, high energy efficiency and durability, consequently reducing running costs such as power overheads or replacement costs. The structure and principal of LEDs Light emitting diodes consist of several layers of semiconductor material that generate light upon the application of DC voltage. In contrast to incandescent lamps an LED is a monochromatic light source, and according to its composition emits light with a specific colour. White-emitting LEDs also initially generate monochromatic light that must then be converted, and this is usually achieved with a combination of blue LEDs with a yellowish phosphor layer or by mixing the light of red,
