the 9th annual ‘lighting fair’ was recently held in tokyo, japan featuring the latest lighting technology.
the annual event focused specifically on environmentally sound lighting products with this year’s theme,
‘lighting, friendly to people and earth’. the event was held inside the tokyo international exhibition center
also known as ‘tokyo big sight’.

the show is world renowned for showcasing the latest products and new technology from new light bulb
innovations to the latest designer fixtures. the show focuses on the domestic japans market but counts
a number of international exhibitors. in spite of today’s economy this year’s show was the largest ever,
featuring 134 companies.

while lighting isn’t the most sensational subject, society’s growing concern for the environment has made
energy consumption and lighting a larger interest. with a green theme, this year’s lighting show aimed to
showcase new products that were environmentally friendly in addition to being economical and efficient.
one of the stand out themes from this year’s show was the LED. many have been promising widely
available commercial LED lighting for years. this year’s lighting show seemed to prove that the LED is
ready for prime-time. technology insiders are confident that LEDs will not only match the level of
efficiency and cost currently enjoyed by fluorescent lights, but exceed it. in order to give you a little more
insight into this theme, we have gathered up some of the main LED lights and technology that made news
at the 2009 tokyo lighting fair.



bar-shaped LED

moritex showed off a new bar-shaped LED lamp called the ‘spectratrue’. the light comes in a variety of
lengths and measures only 20mm in diameter. the lights were a stand out for their high colour rendering
properties that were reported to precisely match the colours of any product. in addition the lamps consume
very little power; 1.7w for the 150mm length and 19.1w for the 1,800mm length.

LED filaments

ushio lighting displayed their ‘LED filament bulbs’ that have a rather deceiving design for an LED light
source. the new light bulbs use tiny LEDs embedded inside a standard glass light bulb. the company has
already begun producing the bulb in a chandelier style and globe form. the LED’s inside the bulb feature
a specially designed transparent packaging, which along with their configuration, spread the light evenly
in all directions. while the may look standard, the ‘LED filament bulbs’ use 0.6w and will last 20,000
hours, 10 times that of an incandescent 5w light.

lumidas LED series

lumidas japan showed off their LED light series ‘lumidas’ which was developed and manufactured by
the korean company fawoo technology. the series features round-head and square shaped LED light bulbs
that boast a luminous efficiency as high as 80lm/w (for reference a standard 100w incandescent bulb has
a luminous efficiency around 15lm/w). these bulbs are much more efficient than standard lights and have
the same colours as electric bulbs. however because this is a rather new technology, the bulbs do cost in
the hundreds of dollars.

fluorescent LEDs

much like the ‘LED filament bulbs’, toshin electric company unveiled the ‘bikei’ LED lamps which look
surprisingly similar to a fluorescent tube. the new design uses the form-factor of the fluorescent tubes,
with the efficiency of LED lighting. the engineers added aluminium fins to dissipate the heat given off
and changed the LED mounting to minimize shadows. the lamp uses 120 blue LED chips to match the
luminocity of a standard 40 w fluorescent. the white light is created by blending the blue chips with red
and green fluorescent materials. the light is designed for uses such as in tunnels or parking lots, where
longevity is a key concern. the ‘bikei’ lamp is rated to last 40,000 hours, five times the life of a standard
fluorescent bulb.

LED town

if one LED can make an impact, imagine the possibilities of an entire town lit entirely by LEDs. toyota is
aiming to find out with their new ‘green avenue azabu no oka’ located in a residential area of japan.
the small development of 204 houses will use over 1,000 LED light fixtures, on the streets and as outdoor
lighting for homes. the area is currently in development and when complete will be the first of its kind.
the lights were strategically placed to provide the ideal lighting, while preventing glaring and other side
effects. the whole system will be 75% more efficient than using standard lighting. the lighting designers
also made sure not to install too many lights. the system provides enough light but never too much.
the area’s model home also incorporates LED lights into the interior.

auto-adjusting light

while it doesn’t use LEDs, panasonic’s ‘twin pa’ fluorescent lamp does feature a special sensor that
automatically adjusts based on the luminance in the room. the recently released lamp, senses a room’s
brightness and will adjust to maintain a constant level of light. by only using the amount of light needed,
panasonic claims the new light could decrease power consumption by 60%. the light is taking light
readers almost every second and adjusts slowly enough so the user doesn’t notice any fluctuations.
panasonic aims to use the new sensor technology in more of their lights in the future.
