LED light source impact designer's thought

Lighting design rules are facing the fate of rewriting. In the near future people will be able to create a previously unexpected lighting effect: an interactive bench emitting a variety of colors, the light of the sidewalk, the wall lights in the "dance" and so on.

Thanks to the current rapid development of LED technology, LED can be integrated into any of the goals, and can provide a dynamic effect of color and brightness can be adjusted. Both indoor and outdoor scene layout (Scene Setting) in the application of LED is the ideal choice, the lighting effect can be good divergence or precise control, at the same time, the designer can choose the color of the light. The use of a single color LED or tricolor LED (red, green and blue) can also be used to produce a different color or a single light source. In order to obtain the ideal lighting effect, the user can directly adjust the color and brightness of the light through the light control function, or select a pre-determined scene.

A typical example of the Croydon, the heart of the business center in the UK, is a place where LED and Centrale are combined with architectural lighting. Colorful color lighting to attract large numbers of tourists into the city's shopping center. Enter the central area, the customer through the broad light colored glass tile walkway to go up, with colored lights hanging in the shopping center across the three layer 14 meters long embraced LED lights, as shown in Figure 1, using 18 slice lamp and 10 strip lamp, light color changing, create a true to life scene.

Corresponding to the season, a total of 19 kinds of lighting effects has been pre fitted in the LED lighting system, with the change of seasons, we can select the appropriate lighting effect, through the control button for example, in the summer to choose the blue lights during the festival can choose red and green lights.

Advanced LED technology with the new development of LED technology, more lighting design tends to miniaturization, long life, high efficiency and sustainability. The performance of the diode has been greatly improved, and the precision of a series of optical sight is increasing, which makes the output light more efficient. On this basis, combined with the art technology, will design a new generation of cutting-edge products. The latest variety of LED light source will enable designers to combine LED lighting and architectural design. PHILPS's LED lighting device integrates a perfect class of high power Luxeon technology from Lumileds Lighting (PHILPS and Agilent joint ventures). Lead free packaged Luxeon light source with industry-leading lumen maintenance performance (without any heating or UV). In addition, Luxeon LED also does not contain any epoxy, which will affect the performance of the light source of various factors are eliminated as far as possible.

The new model Origami is a new generation of LED products, Origami combines DALI and DMX, it has a set of pre programmed color control mode. Origami uniform illumination, with a maximum color change effect, can be made into square, round and rectangular, the surface shows uniform color, dynamic change of color range is not limited. With the characteristics of easy to adjust the color and other characteristics of the James Irvine designers to achieve the summer / winter beam design ideal for innovative ideas (Figure 2).

According to the survey, people in the southern hemisphere countries more love light cold tone, while people in the northern hemisphere countries more love light warm color, in view of the fact is expected to achieve their desired color tone, according to the outdoor temperature, the summer / winter light coordinated atmosphere, in the bright sunny day, providing a cool colors, lighting atmosphere fresh; cold weather, provide a warm and comfortable lighting mode welcomed by customers.

Lighting the combination of architecture and let us look at the LED scheme of the prototype, the Swiss architects studio (architects Atelier O.) has been designed by using LEDflood new design concept of mixed natural and artificial light, LEDflood lamp (Figure 3) allows Atelier O to depict the process of changing the nature night lighting. The light in the building will remain constant through the evaluation and control of night time. Behind the installation of the lamp, a reverse lighting effect (Figure 4).

More and more buildings and exterior design will be shown through the lighting design, not through its structure. PHILPS's LEDflood has been designed in accordance with the combination of lighting and design ideas to improve the structure of colored lights, and expand the scope of the palette. High quality LEDflood combined with its new and long life light source and efficient optical calibration, prompting new, advanced lighting in outdoor applications possible.

Another type of LED lighting is LEDline2, very suitable for modern and ancient buildings, this series of lamps can be used in three versions - flat, concave and convex. The emergence of new technology makes the installation more convenient, power and optical seal unit is easier to integrate.

With the emergence of a new generation of LED light source, urban lighting has completely changed the brightness of light in the decoration and lighting field
