The Hong Kong International Light Fair continues to grow and gain recognition as the world’s most important platform for introducing novel lighting designs and new energy-enriched products.

The 16th edition of the HKILF (Autumn Edition) at the Hong Kong Convention and Exhibition Centre attracted 180,000 global buyers.* and was the most well-attended, as well as the biggest on record.

“Last year, the four-day event attracted 2,360 exhibitors from 38 countries and regions and produced strong visitor turn-out, with more than 38,000 buyers from 144 countries and regions in attendance.”–www.enlightenmentmag.com october 2014

Show highlights include:

• Energy-efficient, eco-friendly “LED and Green Lighting Zones” looking to meet international sustainability requirements.

• New Product Platforms

• Information Exchange Platforms

• New Trends and Styles

–LED and “green” lighting products are expected to see the highest sales growth in 2015.*

–Retail prices of LED lamps are expected to drop by 8 percent by the end of 2015.*

A safety switch is essentially a device that very quickly switches-off the electricity in case any electrical fault is detected. In effect, it reduces the risk of injury & death caused by contact with electricity. Current day safety switches are very different from the ones used even up until a decade ago. Today, it’s mandatory to have these installed in buildings where any kind of electrical addition or upgrade has taken place.

Apart from this, safety switches are also needed for power outlets that that supply electricity to mobile homes like caravans etc. It’s not mandatory to have these safety switches in older homes; however, the recommendation is that you should consider getting them installed. It is one of the most effective ways to protect your family & yourself from electric shock.

ELCBs or Earth-leakage circuit breakers are safety devices used to prevent shock in electrical fixtures which have high Earth impedance. The current installations use the circuit breakers that directly detect leakage in current. Here are some features of an ELCB:

RCDs or RCCBs are essentially modern electrical wiring devices which quickly disconnect a circuit if they detect that there is an imbalance in the current between the energized conductor/s & the return conductor. They are designed to immediately switch-off the electricity supply when the electricity leaking to earth is detected to be at harmful levels. These devices offer very high levels of protection from electric shock.

Voltage Earth-leakage circuit breakers were first introduced around 60 years ago, while the current ELCBs were launched only around 40 years ago. For a very long time, voltage-operated ELCBs & differential current-operated ELCBs were both called ELCBs; this was because it was a far easier term to remember. However, as expected, this common name caused a significant amount of confusion within the electrical industry.

If someone accidently used the wrong one in a particular application, the installations may not get the kind of protection it needed. It was to eliminate this confusion that the International Electrotechnical Commission decided that the differential current-operated ELCBs will be termed as RCD (residual current devices). Any current that’s over & above the load current is referred to as the residual current.

ELCBs have a number of disadvantages such as:

Today the RCD is preferred means of providing effective shock protection. The term is also most widely used across the globe.
