LED Colour Mixing Explained

LED Colour Mixing Explained  LEDs have had a long association with colour, from the advent of visible spectrum red LEDs in the early 1960’s to the ground breaking development of the blue LED by Shuji Nakamura. As soon as blue LEDs became commercially available, lighting manufacturers like Pulsar started to experiment with colour mixing, creating a vast palette of colours from a few carefully chosen light sources. Fast forward to the present day, and LED colour mixing has become the standard for architectural and stage lighting. So why are LEDs so effective at colour mixing? Most light sources produce a broad spectrum of light which has to be filtered out to make specific colours, whereas LEDs are very efficient at making precise specific colours directly from the source. Adding these colours together rather than having to remove large portions of the light spectrum is far more energy efficient, controllable and convenient. Simply by changing the levels of each LED, a massive

Bowman Shoots for UniBay

Bowman Chilled Stores in Spalding is a family run business which has been established for over 50 years. Over the years Mr & Mrs Bowman had a strong influence in large scale horticulture ranging from daffodils and vegetables to cereals. Mr Bowman decided to stop production and to convert existing buildings to refrigerated storage. This included the licence to store meat, fish and dairy produce. He decided to refurbish to industry leading standards to provide excellent services to his customers. The short lifespan of the existing 100 Metal Halide fittings were costing £1.200 a year to maintain and led to reduced light levels and production stoppages when light servicing and replacement were taking place. Pulsar’s maintenance free LED lighting upgrade eradicated all of these issues and their associated costs. After visiting the site and preparing extensive light calculations, Pulsar Light created a scheme with the UniBay130 that dramatically reduced the running cost of the

Flying Scotsman rests with Luxeos

The Challenge Pulsar was presented with the pleasant challenge of illuminating the Flying Scotsman to create a dramatic and atmospheric effect on its return to The National Railway Museum. The bill was to be ensure "bright and of ultra high quality for photography, as well as being unobtrusive". The task was made increasingly difficult as the lighting had to be set up and packed away each evening with only a 30 minute window to do so. Choice of light The solution needed a large amount of light in the right place to be successful. Any large object, such as the Flying Scotsman in its painted livery, effectively absorbs light. i.e. light reflects and bounces all over the place, reducing the impact of what you (and your eye see). The fixtures used needed to by substantial enough to withstand knocks, bangs, kicks and moving in and out each night. With all this in mind, fixtures also must be 100% reliable and configured to operate in exactly the same way each time it was

Lighting the Locomotives – National Railway Museum

Lighting the Locomotives is a Teamwork Triumph at National Railway Museum The Great Hall at the National Railway Museum at York was the singularly impressive location for the 7th annual ‘Locos in a Different Light’ competition. Sponsored jointly by Ambersphere Solutions and Pulsar Light of Cambridge, the aim is to challenge six teams of students from different colleges across the UK who are studying technical lighting at Further and Higher education levels, to each light one of the iconic locomotives in the Museum’s Great Hall. Each team is given a selection of lighting fixtures, an MA dot2 console and two hours to rig and programme their chosen design. Even for those not smitten by the sight and smell of these gigantic engines, there can be no doubting the very real challenge of successfully illuminating one of these heaving beasts of yesteryear. With a limited number of fixtures and with some of the locomotives up to sixty metres in length, not to mention being a 3600 canvas

Eluminate Festival England

Colour your City with Light

“Colour Your City with Light” For the fourth year running Pulsar Light is proud to be a part of e-Luminate Festival Cambridge 2016. Last year’s event saw Pulsar illuminating the Fitzwilliam Museum with great effect. This year, Pulsar's very own Snowy Johnson in collaboration with lighting designer Susie Olczak had the task of illuminating the Senate House and the adjacent Old Schools with the installation being handled by Hawthorn. Susie’s brief was to create a light experience, which the public could interact with whilst viewing the impressive Senate House. This was achieved by creating environment chases and linking them to a control panel which allowed passers by to engage in the spectacle and feel even more a part of the festival of light. Susie created a low energy interactive light installation using Pulsar equipment to illuminate the façade of Senate House. This interactive installation used complementary colours while challenging the audience to make choices

Pulsar Fixtures Illuminate Defining Features – Warsaw, Poland

Cosmopolitan Twarda 4 is Warsaw’s premiere residential skyscraper (160 meters high, 44 storeys), in central Warsaw, Poland. It has 236 apartments, each with floor-to-ceiling windows which provide panoramic views of Warsaw. The building also has a commercial level at ground level, three floors of offices, and a recreation area at level 4 for residents. The tower was designed by architect Helmut Jahn, and developed by Tacit Investment. “To me, urban space is essential to architecture. All my buildings  respond to the existing urban space, while creating it with their arrangement and rhythm” says Helmut Jahn. As part of his design, the tower has a red ceiling above level 4, providing a key visual element from street level and for residents enjoying the recreation area. Pulsar provided a well designed lighting scheme for the red ceiling which took into account desired effect, viewing angles (pedestrians and residents), operating costs and maintenance costs. The solution was 8

Cheltenham Swimming Pool reduce annual running cost by 53%

Council owned Cheltenham Swimming Pool required higher levels of light to better see swimmers and improve the overall look of the facility. Areas of the pool bottom were dimly lit and hard to see in to. Initially equipped with 60 x 400W High Intensity Discharge (HID) fittings burning for 3500 hours per year, the installation had a total wattage of 6 kW and consumed 153,754kWh of electricity per year - generating an annual bill in excess of £20,908. By visiting the site and assessing its needs, Pulsar Light was able to optimise a fixture layout to maximise the light uniformity and improve luminance in key areas, while also reducing the total number of fixtures needed. These features of the Eco-Range solution made a huge difference to the Cheltenham Swimming Pool operation and to the satisfaction of the management and employee team. Pulsar recommended the high brightness EcoFlood 130’s with an 70+ Colour Rendering Index (CRI), the EcoFlood 130 fittings have greatly increased

Light Experiment with e-Luminate
