The Difference of Focus Light, Ambient Light and Decorative Light in LED Lighting Design

Light is actually a ratio, a proportion of light time. In a dark area, a candle is the sun.

Brightly lit nights, dark nights

The Miaoli County government’s policy of spending about 600,000 yuan on lighting 10 bridges a year due to financial constraints has caused a discussion on the community’s website. Some people say that it is good to stay. It is the landmark of Miaoli and guides the county residents to return home. Lights. Some people say that they don’t stay well, and budgets should not be used to spend public money this way.

The two sides held their own views, but they did not have a single conclusion. However, the relationship between lighting and landscaping alone can not help but remind people of the light designer's position to analyze whether the freshwater river needs light sculptures. comment.

Looking at these arguments in order to light up, I can't help but wonder if artificial lighting is too much. Is it true that Professor Paul Bogard said in the Popular Science book "The End of the Night":

“Artificial lighting has its beauty, but overpassing urban lighting will hurt the natural night sky. When the sky gets brighter and brighter, it means the sky is polluted.”

Is every bright, bright night really the future that Edison expected? Does the lively, multicolored night Van Gogh said disappear?

For Dutch lighting designer Rogier van der Heide, this is not the case. Standing in Amsterdam's theatre, he said:

"All the light needs darkness."

We need darkness just as we need light

From the Roman Pantheon to the standard lighting office, Heide simply stated one thing:

"The beautiful feeling of light comes from the corresponding darkness. Only in the dark atmosphere can you have the opportunity to recognize the beauty of light."

Adequate light may meet lighting regulations and requirements, but sufficient light will not allow us to understand the beauty of structure and light, and standard lighting is not a necessary condition for humans when using buildings, such as white organizations providing green energy consulting. (WhiteGroup) The famous office.

With a completely transparent glass that provides the light source, the entire office does not have any lighting equipment. You can find a place to work on your own, whether in direct light or dark corners outside the light source. In fact, the eye can work in different light levels than you think. It doesn't fully comply with standard lighting. It may be a choice, and it may provide us with more changes in the sun. Little fun.

So, through Richard Kelly (1910–1977), Heide proposed three ways of thinking about light.

Focus light, ambient light and decorative light

Focal Glow is used to indicate the position and establish the object to watch.

Ambient Luminescence is ambiguous and ambiguous. It gives the overall environment a relatively low brightness. The landscape and landscape dissolve together and can hide each other and provide security.

 The last is the Play of Brilliant, a small embellishment, like the icing on the cake. There are few, but it can visually create colorful effects.

 Next, let's listen to the speech of lighting engineer Rogier van der Heide. He looks at the world from a new perspective, with particular emphasis on light and dark, giving you different insights.

Before turning on the lights, you can think again

The principle of these lighting designs seems to only be used in theaters and exhibition spaces, but in fact he can use the light in his life to think, whether it is chasing the light like the White Group. Or like lighting designer Jiang Yuyang, according to the different space for the needs of the light at different times, arrange home pattern. Or, learn Rogier van der Heide's use of LED luminaires to reduce light dissipation, reduce brightness and create excess lighting, and so on, depending on the characteristics.

Light can not only bring us vision, but also bring us beautiful feelings. Stop turning the switch on and turn the space to full light. Excess light will only become waste, especially when these light sources are not controlled. Scattered, brightly lit the night, lost the darkness, we can no longer see the stars and moon, or less mysterious vision of the night sky.
