Definitions

  • the LEDs sometimes are mounted on a separate, smaller circuit board and a wiring bundle electrically connects the LEDs to components on the main circuit board.
  • the smaller LED circuit board can then be located adjacent the housing display surface and in a selected orientation so that an optical signal emitted from the LEDs can be more easily viewed.
  • adding a separate LED circuit board and a wiring bundle leads to additional costs and complexity.
  • Figure 4 is a side view of one set of light pipes
  • Figure 5 is a bottom view of the light pipe shown in Figure 1;
  • Figure 2 is a cross-sectional view of circuit board mounting portion 26 of base 12 (shown in Figure 1), and shows openings 40 including upper portions 42 and lower portions 44.
  • Upper portion 42 of openings 40 are configured to slidably engage the first ends of light pipes 14 (shown in Figure 1).
  • Bottom portions 44 of openings 40 are configured to allow circuit board mounting portion 26 to fit over, or be positioned adjacent to, surface mounted LEDs (not shown) on a printed circuit board (not shown).
  • Mounting guides 34 extend from bottom surface 32.
