LED LIGHT TUBE OF MODULE TYPE

摘要

An LED light tube includes a modularized LED base having a recess, one illumination unit and one bridging unit being fixed in the recess, the illumination unit being constituted by LED dies and the bridging unit being constituted by conductive elements electrically connecting the LED dies; a heat dissipation base for receiving and supporting the modularized LED base thereon; a circuit unit disposed on the dissipation base to locate adjacent to one side of the recess; an optical layer covering the illumination unit and the bridging unit; a protection layer covering the optical layer; and a diffusion shield disposed above the dissipation base and having two peripheral sides formed with downwardly and inwardly bent projections slidably engaging two sliding grooves of the dissipation base, thereby enclosing the LED dies therein such that the diffusion shield is located above and transversely to a light emitting path of the LED dies.

主权项

1. A light emitting diode (LED) light tube of module type, comprising:
a modularized LED base having a light emitting side formed with a recess, at least one illumination unit and at least one bridging unit being fixed on a bottom surface of said recess, said illumination unit and said bridging unit being connected electrically via wire-bond technique, wherein said illumination unit is constituted by a plurality of LED dies and said bridging unit is constituted by a plurality of conductive elements, one conductive element being disposed between an adjacent pair of said LED dies; a heat dissipation base for receiving and supporting said modularized LED base thereon and having two opposite peripheral sides respectively formed sliding grooves; a circuit unit disposed on said heat dissipation base in such a manner that said circuit is located adjacent to one side of said recess; an optical layer disposed over and covering said illumination unit and said bridging unit; a protection layer disposed over and covering said optical layer; and a diffusion shield disposed above said heat dissipation base and having two peripheral sides formed with downwardly and inwardly bent projections slidably engaging said sliding grooves of said heat dissipation base, thereby enclosing said LED dies therein such that said diffusion shield is located above and transversely to a light emitting path of said LED dies.
