Color




           
   Your choices are...
 
      
 
   Infrared
 
     An Infrared Emitting Diode (IRED) is a semiconductor junction in which infrared radiant flux is non-thermally produced when a current flows as a result of applied voltage.
 
   Red
 
     LED output is red.
 
   Orange
 
     LED output is orange.
 
   Yellow
 
     LED output is yellow.
 
   Green
 
     LED output is green.
 
   Blue
 
     LED output is blue.
 
   White
 
     LED output is white.
 
   Ultraviolet
 
      The LED output is ultraviolet.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Wavelength




   Peak Wavelength:
 
     The desired output wavelength of LED.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
Array




   Array?

     LEDs are packaged as multiples.  LED arrays will contain a certain number of elements (LEDs).
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
More Specs




   Forward Voltage:
 
     The forward voltage the LED operates at.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Forward Current:
 
     The forward current the LED operates at.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Luminous Intensity:
 
     The luminous intensity of the LED in mcd. The candela (cd) is the luminous intensity of a light source producing light at a wavelength of 555.17 nm with a power of 1/683 watt per steradian, or 18.3988 milliwatts over a complete sphere centered at the light source.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Optical Power Output:
 
     The optical power output of the LED in mW.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Viewing Angle:
 
     Dependent upon diffusion from the lens, usually the larger the viewing angle, the less bright the LED.  Diffused types generally have larger viewing angles and non-diffused types have smaller viewing angles.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Dual?
 
     Two LED lamps in the same housing.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Bipolar?
 
     Bipolar LEDs work even if voltage is reversed.  Select models change color on reverse voltage.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   LED Construction       
   Your choices are...
 
      
 
   Edge Emitting LEDs
 
     A light emitting diode (LED) with output that emanates from between the heterogeneous layers. It has greater radiance and coupling efficiency to an optical fiber or integrated optical circuit than a surface-emitting LED, but not as great as the injection laser.
 
   Surface Emitting LEDs
 
     A light emitting diode (LED) that emits light perpendicular to the active region.
 
   Super Luminescent LEDs
 
     A light emitting diode (LED) based on stimulated emission with amplification but insufficient feedback for oscillation to build up.
