When LED's are combined with loudspeakers light and sound can be efficiently distributed into
an area. Many designs of these Light Speakers can be combined to serve multiple purposes. For example they
can easily be integrated into most standard construction (retro fit). Performance is improved and energy
consumption is lowered because the components represent the latest in green technology. These state of the art products can
be used to produce combined visual and sound effects that can open up a space. LEDspeakers are also an effective
way to both illuminate and project audio into a room while maintaining the aesthetics of the decor. LED's are very efficient
so they run cooler and draw less power than conventional light bulbs. LED's also last a lot longer. They are safe and
reliable. These qualities along with their durability make them a good solution for Mobile applications such as car,
marine and aviation audio systems running on 12V power. Other applications include.

We are
able to custom design systems that integrate LED's and loudspeakers. We have the experience to engineer solutions for
mobile, residential and industrial applications. LEDs bridge the gap providing light to sound systems. For more
in depth information please vist http://www.ledloudspeakers.com This is where you can find more technical explanations.
A Light Emitting Diode (LED) is a solid-state semiconductor device that converts electrical energy directly into
light. On a basic level, this semiconductor is comprised of two regions. The p-region which contains positive electrical
charges and the n-region which contains the negative electrical charges. If you apply voltage a current
begins to flow and electrons move across the n region into the p region. The process of an electron moving through the p-n
junction releases energy. The dispersion of this energy produces photons with wavelengths in the visible spectrum.
Because LED's are solid-state lighting devices they do not contain any parts
that can break, rupture, shatter, leak or contaminate the environment. (RoHs compliant) If we used more LED's to
replace conventional light sources CO2 emissions would be significantly reduced. LED's exceed Energy Star requirements. They
are robust light sources. They are perfect for low voltage applications.(Safe) The light emitted can be easily
directed to increase the overall system efficiency. They are able to produce vivid saturated colors without any filters.
The small size of LEDs allows them to be tightly mixed together for different lighting effects. They can be digitally controlled and
turned on-off at lightning speed. They have extremely long life spans typically + 50,000 hours. LEDs provide high quality
light with superior color rendering that is ideal for product merchandising environments. Unlike other light sources
LED's do not emit UV light which can be harmful to fabrics.

The plots below represent the sound output of a column speaker at different frequency
bands. These balloons represent the directivity of the speaker. The light emitted by an
LED also has directivity. By carefully selecting the number and type of LEDs it is possible to create a light
source that closely emmulates the loudspeakers sound dispersion pattern. This is just one example of the possibilities
of this technology.

A flush mount two way coaxial speaker with a centered LED light. The light level is adjustable via
remote control. The control unit can be installed in a standard single gang electrical box. Optional transformers
allow this speaker to be used in multiples as part of a 70 Volt distributed system. This speaker is shallow enough to
fit in a standard stud depth wall. It can be installed in existing buildings or new construction. The non rusting
aluminum grille is paintable and removable. All speaker mounting can be done from the front so there is no need for
access behind the wall or ceiling. Multiple speakers can easily be controlled and integrated into a network. These
speakers and LEDs run on low Voltage so they meet code and are safe to use. Getting the sound/lighting sources closer
to people greatly reduces distortion and increases efficiency.
