Hong Kong airport with LED energy-saving lighting design

Promotion, popularization and application of LED lighting technology and a wide range of products, so all types of energy-saving lighting in the country places possible and trends. However , in the specific energy-saving lighting projects , but often because the manufacturers and owners emphasis on " saving " the number of dimensions to consider , ignoring the lighting quality ( such as glare control , color rendering and color temperature , etc. ) dimensions of demand, thus resulting in some well-designed project , after the transformation of the lighting effects greatly reduced. After reportedly replaced with LED saves 50 % of the electricity reform in Hong Kong Chek Lap Kok airport that is regarded as one example.

Chek Lap Kok Airport in Hong Kong , we can still see the original lighting design in the pursuit of high glare control and high standards , as well as careful layout and design aspects of the spatial intensity distribution . However, after energy-saving LED glare control obviously incompetent a little force .

Exit aisle -based lighting uses a dual tube T8 Grille , lighting darker cavity itself , cut the light angle, glare control is very good. If not out of habit looked closely, the basic feel the presence of the lamp . This has now been replaced with LED lights the lamp , the effect can be.

The middle of the light with the introduction of natural light to supplement the indoor lighting. T8 Grille even as both sides use the lights, you can see the brightness of the left wall of the higher right part of the glass partition wall , part of the light box.

A closer look at the following picture of the two rows of lights , you will find all the polarizing wall wash light distribution design , the designer can see the care and thought : Left row of wall wash lights enhance the visual brightness of the wall , the right row of lights with the role of the conveyor belt in order to improve on the vertical illumination ; considering the needs and requirements of visual comfort and communication function space .

Replacing LED downlights can be said to be a flaw. After this replacement lamps , the entire airport space , everywhere they have caused glare . I think the only explanation can be made far-fetched , that is at the end of the conveyor belt , you need to use " harsh glare " to be alert to travelers .

Introduction of natural light , a combination of secondary reflections and Spotlights , the left and right side of the figure below two-story LED downlights on the map is still a " bright spot ."

Metal Halide Downlight original use , glare control was significantly better than the above LED downlights , vision does not appear to direct light.

Indirect light down lighting used to create a low open space comfortable environment . Fortunately, because the LED lamps can not be 360 ° light, did not do the replacement , still keep the original T5 light.

This is the exit to the transition area after baggage waiting area , the space is very low ( about visual 2.5m ) , using a secondary reflector lamp panel surface mounting , looks very noisy , right ?

But if you stand baggage hall of view ( picture on the right ) , you will find that the entire space is concerned, this area is necessary to improve the brightness of smallpox .

From the above chart we can see the entire high baggage hall space, light is good, but the basic feel of lamps exist , like the outdoors , like on a cloudy day . Good spot walls leaked secrets visual perspective : LED light source to replace traditional fluorescent light sources is another flaw with the light fixture becomes very strange . And the light blue color is a very light make people uncomfortable .

Energy-saving lighting currently carried out in full swing , in fact, there are many "myths ." These errors, such as not taking into account only the energy-saving lighting quality for consideration, as the owners, designers and manufacturers , the role of these stakeholders in the project under way , in part, really do not understand , some do not want to know , some people are deliberately confuse .

Finally, a little joke to satisfy users:
A man went home to his wife: I saved a dollar today , I followed the bus to run back.
His wife said angrily : how do you not follow the taxi and ran , you could save ten dollars too!

Although the joke is a joke , but there was a lot of domestic energy-saving projects out of the data , I am afraid it is, " followed by a taxi run ."

The difference is that this really money .
