Patent attributes
A lighting device includes a light-guiding rod and a light-emitting unit. The light-guiding rod includes a transparent hollow housing, the housing has two open ends and two insulating plugs for closing corresponding said two open ends. The light-emitting unit includes a transparent light-guiding plate, at least one light-emitting diode, a mounting substrate, and a plurality of conductive bumps. The transparent light-guiding plate is disposed in said housing. At least one light-emitting diode has a light-emitting surface; the surface is attached to a lower surface of said light-guiding plate. The mounting substrate has a wiring surface and a plurality of electric traces. A plurality of conductive bumps for connecting electrically said electric contacts of said at least one light-emitting diode to corresponding said electric traces in such a manner that said at least one light-emitting diode is mounted on said wiring surface of said mounting substrate.
