  • What is the difference "Luminance" and "Luminous Intensity" ?
    • Luminous intensity refers to the overall brightness, from a lamp LED, for example, without regard to the area of the light source. Luminance indicates the degree of brightness over an area, such as from a display device. The greater the source area the higher the luminance. The luminance is normally obtained by dividing the luminous intensity by the light source area.
    • Products: LED  
  • Is reflow soldering possible for all LEDs?
    • No, some LEDs should not be reflow soldered. Chip LEDs are suitable for reflow, while lamp types (through-hole/leaded) should be flow or dip soldered. Soldering conditions and information are contained in the respective data sheets, and vary by manufacturer.
    • Products: LED  
  • Are there any ways to extend the life of LEDs ?
    • One of the major factors that influence LED life is die temperature – the lower the temperature the longer the life.
      In order to maintain low LED die temperature the following should be heeded:
      •Keep current flow small
      •Minimize ambient temperature
      •Design for sufficient heat dissipation

  • Is it ok to use LEDs outdoors?
    • LEDs in general are not designed to be used outdoors.
      Adequate moisture treatment, temperature management, UV filtering, salt air protection, and the like should be provided if intended for outdoor use.
