Choosing Efficient Light Sources for Exit Signs Illumination in most
offices usually comes from direct-indirect light sources or natural and
artificial light. It provides uniform light level across rooms and other areas
of the workplace. This is essential for people carrying out work as proper
lighting can improve ambiance, prevent light-related stress and promote the
effective use of office resources. Apart from the overall general lighting, you
can find accent lights including those illuminating paintings, cabinets, exit
paths and so on.
For light sources used in exit sign systems, there are
several innovations or light upgrades which can help reduce energy and the
maintenance cost. Since these exit signs operate for the whole day, it's best to
utilize those that can give value for your money and they don't need to be
expensive or complex to lead you out during an emergency. There are basically
many choices of light sources, fixtures and power supply solutions to consider
and finding the ideal one is possible with the use of the Internet, printed ads
and other means of lookup. In selecting which type of emergency exit sign to
have, it's useful to explore the latest and widely used products out there.
As traditional light products such as standard incandescent lamps have
been found to be low efficient and short-lived, the use of alternative light
sources in exit signs has taken over. In fact, most people and businesses have
used and installed them, and one of these alternatives that effectively
illuminates is the Light Emitting Diodes (LEDs). They can operate for more than
25 years and provide good visibility and low wattage. Another good light source
is the Electrolumiscent panels which can last for about 8 years and can give off
a highly uniform brightness. Then, one more popular exit sign innovation is the
radioluminescent tubes which are filled with
tritium gas and they basically
don't need electrical or battery power to function. How does it work? The beta
particles from the gas basically moves and hits the tube's phosphor coating,
therefore light is produced. These
tritium
exit signs can work for more than 10 years and pose no real danger to health
as tritium is considered a low level nuclear waste. Yet in the event that the
tube breaks or leaks, state regulations dictate that all employees must evacuate
until the spill is properly removed. Also, recycling the tritium inside the tube
is done when it starts to lose light. Overall, the use and placement of these
exit signs are duly regulated by state agencies and offers a better safety and
energy saving solution.
