Square With 5Ф Dome 4 Lead Ultra Red LED led light components



  1. Fewer LEDs required.
  2. Low profile.
  3. Lowers lighting system cost.
  4. Super flux output.
  5. Viewing angle=45°.
  6. Emission color coordinates: Ultra Red.
  7. The product itself will remain within RoHS compliant Version.


  1. This revolutionary package design allows the light designer to reduce the number of LEDs required and provide a more uniform and unique illuminated appearance than with other LED solutions.
  2. The low profile package can be easily coupled with reflectors or lenses to efficiently distribute light and provide the desired light appearance.
  3. The white LED which was fabricated using a blue LED and a phosphor, and the phosphor is excited by blue light and emits yellow fluorescence the mixture of blue light and yellow light results in white emission.
  4. Utilizing advanced InGaN chip technology.


  1. Automotive exterior lighting.
  2. Electronic signs and signals.
  3. Special lighting application.

  1. Luminous Intensity (Flux) is measured with a light sensor and filter combination that approximates the CIE eye-response curve.
  2. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
  3. It use many parameters that correspond to the CIE 1931 2°. X, Y, and Z are CIE 1931 2°values of Red, Green and Blue content of the measurement.
