LEDs
We carry
a full line of LED's for your fiber & electrical projects. Select from many
of our connectors listed below!
All of
the following LED's are not your low-level brightness Radio shuck type variety;
they are High-Brightness (mcd) Micro candela 20mA draw. They vary from 1.8 vdc
to 5 vdc and come in many colors.
If
you wish to know more about L.E.D.'s please click on link below.
What's a Led?
An LED
is a Light Emitting Diode, like an electronics diode it lets electricity flow in
only one direction. The little wire encapsulated in the epoxy center emits light
when electricity flows from the Cathode (positive lead) to the Anode (negative
lead). Photons are then released to travel to your eye which are detected by
your rods and cones and sent to your brain, no mater what size!! An LED can last
from 11 years and longer, far out lasting a standard bulb so you see why we use
them for Fiber Optics.

CAUTION:
These LEDs are extremely bright; do NOT look directly into them.
*********************
LEDs are static sensitive, use static handling precautions. *The MCD rating is a
relative number. 5MM Package with
0.1 inch lead spacing. These
devices are used for general-purpose lighting and we provide detail
specifications if needed. LED technology moves very fast, therefore supply and
exact specifications are often limited and fast changing. We do not recommend,
high volume design-in of these items. A single White or Blue LED will last from
1000 to 10,000 hours, NOT 100, 000 hours like some factories claim!!!
LED, In a dark room can illuminate a full 8 1/2 x 11 sheet of paper for reading.
Two LEDs can be used to light an entire computer keyboard.
Specifications may change without notice. All leds must be used with current
limiting resistor.
Resistors sold by us!
Current limiting series resistor formula:
vIN - vLED / 30 milliamp = series current limiting resistor.
((5V - 3V) / 0.030) = 100 Ohm series resistor for a 5V supply.
((6V - 3V) / 0.030) = 100 Ohm series resistor for a 6V supply.
((9V - 3V) / 0.030) = 200 Ohm series resistor for a 9V supply.
((12V - 3V) / 0.030) = 300 Ohm series resistor for a 12V supply.
Change
the mA to 0.020 if using a 20mA LED

HERE FOR THE RESISTOR CALCULATOR
If you are driving several LEDs, you must use a separate series resistor for
each LED. Each LED must have it's own current limiting series resistor.

RGB Color LED
5mm
Our New 5mm Clear lens RGB LED flashes with a series of quick flashes; red, green, blue, red+green,
green+blue, blue+red, and then all three at once. It repeats this fast cycle 2
times. Next, the red fades on, stays on for about 2 seconds, then fades out.
Same with green, then blue, then red+green, green+blue, blue+red, and then all
three. It does this slow fade for two entire cycles; then everything begins
again. 20-25mA, the voltage drop ranges from 2.94v with all segments lit, to
around 3.6 volts

Mixing Primary and Secondary Color Paddles are used for experiments involving
additive and subtractive color, color mixing, color transmission, absorption and
filtering of the different wavelengths of light.
Diffraction Gratings are used for the direct viewing and analysis of spectra
from different light sources. Experiment with both the 13,500 line/inch and the
500 Line/mm. The diffraction gratings are the principal component in a
spectroscope and can be used for many of the same experiments. View the spectra
from different gas tubes. Polarizing Filters are used for experiments involving
birefringence, light scattering, polarized filter experiments, light reflection,
Brewster's angle, how polarized sunglasses work and much more!
