Illumination device for simulating neon or fluorescent lighting including a waveguide and a scattering cap

摘要: An illumination device includes: an optical waveguide having a first lateral surface for emitting light and second receiving light; scattering cap secured to the of extending substantially length waveguide; source (e.g., plurality LEDs spaced predetermined distance from one another) positioned adjacent light-receiving waveguide. Light entering is efficiently transmitted then preferentially scattered so as exit with broad elongated intensity distribution pattern being formed along cap.
