留意室外照明的設計 Designing Lightings to Become more Dark-Sky Friendly

香港有部分大廈室外燈光裝飾,刻意將光線照上天,刻意增加了光害!曾有傳媒查詢中環某座摩天大廈為何在天台加裝向天的強烈射燈,晚上將燈光刻意照上天。該大廈的設計師回覆說:「希望利用照上天空的強烈射燈製造『天人合一』的感覺!」。以我們的角度,該大廈的刻意照明造成嚴重的光害,掩蓋了星空,「人」與「天」變得更遙遠,完全達不到「天人合一」的效果!

Some of the outdoor lighting decorations on buildings' walls in Hong Kong painstakingly focused the lightings to the sky. Their designs surely increased the light pollution! Reporters asked why there are extensive up-lighting beams at night at the roof top of a skyscraper at Central. The designer replied that he would like to use the upward beams to being out "Heaven and human are the one" concepts. From our point of view, this skyscraper not only cannot achieve the concept, but the lightings also masked up the starry night and separated heaven and human!

在晚上,中環國際金融中心二期像一支「巨型電筒」,將光能白白散逸到宇宙去,造成嚴重光害之餘更浪費不少電力。

At night, Two International Finance Center in Central likes a huge torch. The light emitted by the building causes serious light pollution and wastes many energy.

上環某高樓大廈天台的照明刻意照射上天,是另一支「巨型電筒」。不難發現大廈上面的雲塊被照光了,雲塊反射人為燈光造成光害。

Another "huge torch" near Sheung Wan equips upward outdoor lightings. It is easy to see that the clouds just above the building are brightened and reflects human light and cause light pollution.

不單現成的高樓大廈無助減少光害,建築中的大廈地盤都裝上了強烈的向天射燈。這張照片在2006年年中拍攝,右方清楚見到當時興建中的大角咀某樓盤的射燈。

Apart from tall buildings, construction sites also installed extensive upward lightings. Taken at the middle of 2006, two light beams emitted from a construction sites in Tai Kok Tsui are clear in this picture at the right hand side.

另外,原址是「虎豹別墅」的渣甸山豪宅「名門」的外牆光纖燈飾測試,曾被附近居民投訴,指光度太強及經常閃耀,引起他們不安。

People complained about the testing of light fibers decorations of The Legend at Jardine's Lookout, located at the old site of Tiger Balm Garden in Tai Hang, Hong Kong Island. People were annoyed by the large intensity and glittering of the decorations.

相反,香港有大廈設計師在設計大廈室外照明時,考慮了光害,設計了既不製造光害,也能達至粉飾大廈外牆的照明。

On the other hand, some designers considered light pollution in their designs of lighting decorations of buildings' walls. They designed fascinating decorations without enhancing light pollution.
