Laser Light Vs L.E.D. Light

Light emitting diodes (LED) are tiny light bulbs
but which have become enhanced dramatically over
the last few years due to new LED techology.
Unlike ordinary incandescent bulbs, they do not
have a filament inside so they last longer and
they are much brighter. LED’s create light
solely by the movement of electrons in a
semiconductor material within the small vacuum
bulb. LED’s produce bright light in various
wavelengths and LED light offers an amazing
‘vehicle of light’ for pulsed patterning and
digital signaling therapy. LED light has been
used in animal health for years, due to the
simple way that light can offer the necessary
energy to provide healing without the risks of
ambient light damage to the eyes. The healing
for both types of light therapy, comes from the
conversion of photons to electrons. Light from
LED’s do not offer extreme tissue penetration
compared to laser light, but they provide the
opportunity for the light to become available to
the body in a natural and powerful way, that is
well beyond natural sunlight. The LED principle
is based on compression or light density. Old
incandescent lights provide little healing
value, due to their lack of ‘frequency’ and
inability to concentrate enough light into one
place.
LED is available in very low voltage, and
it comes in various ‘NM Lengths or frequencies:
The
theory of light compression is more about lumens
(brightness) rather than coherence or
penetration (laser). Lumen density
aka, compression, offers the ability for
the light to transfer through the tissues in a
way similar to trans-absorption, rather than
being injected or ‘focused’ into a specific area
of tissue. General illumination or light
transfer has the capacity to open up the
pathways of connection because all light be it a
laser or an LED is the same in one aspect… it’s
all based on a single thing--a photon.. and
photons bring electrons when they enter the
body. With
Low Level LED Therapy it offers an
abundance of
photons all available for use in the
body—lasers just have them all running parallel
to each other. So what you get from a laser in
concentration you make up for in abundance of
photons. In fact, there is very minimal
difference between a low level laser and LED
therapy at low voltages. The benefit of the LED
therapy, is the risk with lasers can damage eye
tissues if they inadvertently reach the eye, or
they can damage the tissues if they are too
strong. In those cases strong lasers are known
as ‘hot lasers’. But LED light therapy is a safe
and effective alternative and it has the same
semiconductor capacity to carry imbedded signals
through a pulsed patterning system.
The first law in photochemistry (Grotthus-Draper
Law), states that light once absorbed creates a
molecular reaction. photochemistry can occur, it
is well known that the surface of the skin can
carry the information of light through the
transdermal tissues, much light acupuncture
points and through waterous tissues. Light
signaling has been documented by touching a
light to an acupuncture point and measuring
changes in the meridian through muscle testing.

Wavelengths and Impact of Penetration
and Absorption.
Portions of these diode wavelengths are
visible, from 600 up to approximately
780 or 820 nm. Humans have a declining
ability to see light above approximately
820nm. Photon energy increases as the
wavelength decreases; conversely,
penetration through the skin increases
as wavelength increases. Thus, certain
conditions may benefit from lower
wavelengths where most of the energy is
absorbed at the surface, and other
conditions may benefit more from higher
wavelengths that permit deeper
penetration. It follows that an ideal
wavelength for treating most conditions
would be in the midrange.
