Abstract

A LED illuminating module includes a supporting frame and an illuminating unit. The supporting frame has a top surface and an elongated reflective channel indented on the top surface and defining a peripheral reflective wall inclinedly extended from a bottom wall of the reflective channel. The illumination unit includes a light circuit supported by the supporting frame and a plurality of illuminators which are electrically mounted to the light circuit and spacedly aligned along the reflective channel, wherein each of the illuminators forms as a point of light source for radially emitting light towards the reflective wall, such that the reflective wall is adapted for reflectively accumulating the lights of the illuminators within the reflective channel, so as to merge the points of light source to form a line of light source along the reflective channel.

Claims

1. A Light Emitting Diode (LED) illuminating module, comprising:

a supporting frame having a top surface and an elongated reflective channel indented on said top surface and defining a peripheral reflective wall inclinedly extended from a bottom wall of said reflective channel; and

an illumination unit comprising a light circuit supported by said supporting frame and a plurality of illuminators which are electrically mounted to said light circuit and spacedly aligned along said reflective channel, wherein each of said illuminators forms as a point of light source for radially emitting light towards said reflective wall, such that said reflective wall is adapted for reflectively accumulating said lights of said illuminators within said reflective channel, so as to merge said points of light source to form a line of light source along said reflective channel.

3. A LED illuminating module, as recited in claim 1, wherein said reflective wall has a reflective inclination angle corresponding with a projecting angle of each of said illuminators.

5. A LED illuminating module, as recited in claim 1, wherein said reflective inclination angle of said reflective wall is larger than 90°

and smaller than 120°

with respect to said bottom wall of said reflective channel.

8. A LED illuminating module, as recited in claim 1, wherein said bottom wall of said reflective channel is a flat surface adapted for reflectively accumulating said lights from said illuminators within said reflective channel, so as to enhance said points of light source to be merged to form said line of light source along said reflective channel.

9. A LED illuminating module, as recited in claim 5, wherein said bottom wall of said reflective channel is a flat surface adapted for reflectively accumulating said lights from said illuminators within said reflective channel, so as to enhance said points of light source to be merged to form said line of light source along said reflective channel.

10. A LED illuminating module, as recited in claim 6, wherein said bottom wall of said reflective channel is a flat surface adapted for reflectively accumulating said lights from said illuminators within said reflective channel, so as to enhance said points of light source to be merged to form said line of light source along said reflective channel.

11. A LED illuminating module, as recited in claim 1, further comprising a sealing housing sealedly mounted below said supporting frame to define a receiving cavity therewithin to sealedly receive said light circuit, such that when each of said illuminators is spacedly supported at said sealing housing to electrically connect with said light circuit, a head portion of said illuminator is outwardly protruded from said top surface of said supporting frame to dispose within said reflective channel

12. A LED illuminating module, as recited in claim 8, further comprising a sealing housing sealedly mounted below said supporting frame to define a receiving cavity therewithin to sealedly receive said light circuit, such that when each of said illuminators is spacedly supported at said sealing housing to electrically connect with said light circuit, a head portion of said illuminator is outwardly protruded from said top surface of said supporting frame to dispose within said reflective channel.
