Ubli or Uble, like the local people call it, is situated on the south-west part of the island. Ubli is the port of Lastovo.

The construction of a new building provides architects with an opportunity to embrace new technology to reduce the site’s lifetime carbon footprint. Solid-state lighting’s (SSL) high efficiency and longevity is making it the number one choice for lighting in environmentally-conscious projects.
Consumer electronics giant Apple, for example, has standardized on LED lighting for all facilities undergoing construction or major renovation. 1 However, fitting SSL to existing buildings brings several challenges. Conventional incandescent bulbs or fluorescent tubes run directly from the AC mains supply. In contrast, LEDs require a low-voltage, constant-current DC supply, so connecting SSL to legacy wiring demands the use of specialized power supplies known as LED drivers. Theses LED drivers add expense, take up space, and generate heat.

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book.
But, recently an alternative––which is particularly suited to modern office environments and which could significantly push down the cost of retrofitting SSL––has come to the fore: Power-over-Ethernet (PoE). PoE allows the wiring of a local area network (LAN) to carry both data and power to connected devices. This article explains the advantages of PoE-based LED lighting infrastructure over other wiring systems and describes how designers can implement PoE SSL solutions by taking advantage of the latest generation of wide-voltage input, constant-current LED drivers. Retrofitting LEDs A typical office environment is dominated by the steady cool-white glow of fluorescent lighting. While fluorescent tubes exhibit reasonable efficacy, averaging 60 to 100 lm/W, their electrical performance has been eclipsed by the latest generation of LED lights.
Even “mid-power” LEDs such as boast an efficacy of 122 lm/W (at 3 V and 150 mA). High-power devices (which are a little more expensive) such as can push out over 150 lm/W (at 2.95 V and 1.05 A). LEDs also boast longer lifetimes than fluorescent tubes.
In normal use, an office manager might reasonably expect a fluorescent tube to last around 10,000 hours — LEDs routinely shine for five times as long; and fluorescent tubes do bring some environmental concerns due to the mercury used in the lights. The amount of mercury is small, but the health effects of this heavy metal are cumulative so careful disposal is required. No such toxic metal issue occurs with LEDs. It’s perhaps of little surprise then that companies such as Apple are keen to switch to SSL to illuminate their operations. Fluorescent tubes operate from an AC mains supply (some tubes can operate from a DC source, but this is unusual) at currents from 400 mA to 1.5 A. Ornamen undangan cdr.
