Japanese LED traffic lights just too cool when snow falls

Tokyo (AFP) – Energy-saving LED traffic lights seemed like a cool way to cut back on electricity costs, but Japanese police said Monday they might just be too cool — because they don’t melt snow.

Light-emitting diodes (LEDs) account for around 45 percent of all of Japan’s stop-and-go signals and that proportion is growing as local authorities cotton on to their economising possibilities compared with regular incandescent lights.

But in wintery northern Japan the lights have encountered a problem — drivers can’t see them because they don’t get warm enough to melt accumulated snow.

Akira Kudo of Aomori Prefectural Police said snow has to be removed manually between December and mid-February during blizzards.

“We don’t have enough staff members to remove snow as more and more LED lights are being introduced,” he said.

LED lighting is becoming ever more popular in public and private spaces because of its lower energy consumption.

The technology has been big news in Japan since three local-born physicists won the Nobel Prize last year for the development of the blue LED, the breakthrough that led to the white LED now commonly used worldwide.

Celebrating the 168th birthday of Thomas Edison

edison

Last Wednesday 11th February was a significant date for any supplier of light bulbs like ourselves here at Easy Light Bulbs, given that it was the birthday of Thomas Edison, who was born on that date in 1847. The American inventor and businessman was responsible for the development of so many devices that continue to greatly impact on our lives today, from the phonograph to the motion picture camera.

But of course, Edison’s biggest ‘hit’ will always be the electric light bulb, even if it’s true that the man widely known as ‘The Wizard of Menlo Park’ certainly did not invent it – rather, his great achievement was in making it practical and long-lasting enough to become a widespread fixture in the average person’s home. Edison’s first commercially practical incandescent light simply built on a series of earlier – but much less cost-effective – incandescent lights developed by the likes of Humphry Davy, James Bowman Lindsay, Moses G. Farmer and William E. Sawyer.

Indeed, the history of incandescent lamps went right back to Alessandro Volta’s demonstration of a glowing wire in 1800, but despite all of the advances made since then, by the late 19th century, many incandescent bulbs still suffered from such problems as expensive production costs and a short lifespan that made them far from commercially feasible. Following experiments with platinum and other metals, Edison returned to his earlier work with carbon filaments, eventually filing for US patent 223,898 (granted on January 27, 1880) for an electric lamp using “a carbon filament or strip coiled and connected to platina contact wires”.

Several months after the granting of this patent, however, Edison and his team discovered a carbonized bamboo filament capable of lasting more than 1,200 hours. Back in 1878, the Edison Electric Light Company had been formed by the inventor alongside several financiers – including J. P. Morgan – in New York City, with the first public demonstration of the incandescent light bulb taking place on 31st December 1879. It was a key step on the road to realising Edison’s ambition to “make electricity so cheap that only the rich will burn candles.”

The rest, as they say, is history. Edison, who died aged 84 in 1931, is now nothing less than light bulb royalty, and we certainly can’t say that Easy Light Bulbs would exist if it wasn’t for him. Browse our complete range of light bulbs today to see the endless possibilities that now exist for Edison’s remarkable ‘greatest hit’.

Industrial bulbs provide the traditional light of filament bulbs with added durability

Easy Light Bulbs is aware that many people throughout the UK still prefer the warm, traditional glow of old fashioned filament light bulbs, but are unable to find them due to the government’s recent bans. We think that every customer deserves the lighting option of their choice, so we’ve made a huge array of industrial – or ‘rough service’ – bulbs available. These provide the same glow as filament bulbs but last much longer, allowing you to bypass the ban and get what you want.

As their name suggests, these bulbs are designed for use in industrial settings where a greater resilience to damage is required. Within these environments, vibrations, incidental damage and other external pressures can easily cause bulbs to fail, so industrial models are manufactured with an additional wire within the glass enclosure, providing greater filament support. This support allows them to withstand those physical stresses, while also dramatically improving their expected life. Where a standard incandescent might have lasted 1000 hours, an industrial model will usually keep burning for 3,000 hours.

However, you’ll still get a bulb that both looks and works exactly the same as an older bulb. In fact, you can’t even tell the difference once they’re lit. This is what has made them so popular with consumers after conventional lighting options were made obsolete: you get the same performance with added longevity. As an additional plus, they also tend to be cheaper than newer light bulb options, such as halogen and LED.

Easy Light Bulbs has a large inventory of these bulbs, with many designs and wattages available. In our online store, you’ll find both G95 round bulbs and GLS bulbs in 22mm bayonet and 27mm screw-in varieties, as well as candle bulbs and golf ball bulbs, which are additionally available in 15mm bayonet and 14mm screw-in configurations. We even stock a large selection of miniature bulbs.

If you want your home to be warmed by the light of a traditional filament bulb but have been unable to find them, then we reckon an industrial model is exactly what you’ve been looking for.

Discharge lamps – we really do offer them all

Anyone doubting the commitment of our team here at Easy Light Bulbs to sourcing the broadest possible range of light bulbs would only need to look at our staggering range of discharge lamps. Defined as lamps in which the light is produced in a gas-filled glass enclosure by an electric discharge, discharge lamps are known for their very high luminous efficiency, which has made them a popular choice for industrial and commercial environments.

Naturally, that has led to a lot of commercial and industrial customers turning to us for discharge lamps, but they’re also fast gaining popularity among homeowners, who are using low rated discharge lamps as direct replacements for filament lamps. There are many categories of discharge lamps, from fluorescent, low pressure mercury vapour lamps that are widely used in homes and offices as general lighting, to the highly efficient, low pressure sodium lamps that are favoured for street and road lighting.

Certainly, if you are looking for an extensive selection of discharge lamps, there really is no better online store than Easy Light Bulbs. Sodium, mercury and metal halide technologies are all represented in our range, with reflector, double-ended, tubular and elliptical shapes all in stock from world-leading manufacturers like GE, Philips, Osram and Venture.

Do you need double ended discharge lamps, with or without leads? What about FC2 blade double ended lamps, G12 halide discharge lamps, SOX bulbs or two pin white son lamps? Other sought-after offerings of ours include Super Mini GU6.5 Twist & Lock and PGJ5 CDMTM Twist & Lock lamps.
