Go, do not influence or have little influence on the illumination effect of diode chip for backlight unit 3, and another part is reflected by heat conduction bar 8, by heat conduction bar
The light portion of 8 reflections is directly reflected away, remaining to reflex to reflecting drum 7, is finally also reflected away by reflecting drum 7.This reality
In applying example, it is preferred that heat conduction bar 8 be arranged in parallel with reflecting drum 7 or less parallel is set, so that being reflected by heat conduction bar 8
Light nearly all reflect away, the secondary reflection without may require that reflecting drum 7.
Radiating diode package structure high provided in an embodiment of the present invention, during preparation, first can be welded to base by heat conduction bar 8
On plate 1, the encapsulation of substrate 1, heat conduction bar 8, radiating piece 2 and diode chip for backlight unit 3 is finally carried out, it is also possible to after encapsulating structure,
Cavernous structure is opened up on packing colloid 6 by laser-induced thermal etching or other methods until substrate 1, finally inserts in cavernous structure
Enter heat conduction bar 8.
Radiating diode package structure high provided in an embodiment of the present invention, heat conduction bar 8 in packing colloid 6 is by heat transfer
To substrate 1, heat is distributed by radiating piece 2 by substrate 1, at the same heat conduction bar 8 by the reflector layer of its outer wall by diode
The light of the hair of chip 3 is launched, in addition the overcoat reflecting drum 7 of packing colloid 6, is prevented in terms of two because of setting heat conduction bar 8
Influence the illumination effect of diode chip for backlight unit 3.
In the present embodiment, as shown in figure 3, further, the one side of the heat conduction bar 8 is curved reflection face, the arc
Reflective surface is oppositely arranged with the diode chip for backlight unit 3, and curved reflection face is anti-for collecting the light that coalescence launches diode chip for backlight unit 3
The outside of packing colloid 6 is mapped to, so that heat conduction bar 8 does not interfere with the illumination effect of diode chip for backlight unit 3 not only, one is entered on the contrary
Step lifts its luminous compacting effect.
In the present embodiment, further, the radial dimension that passed through on the heat conduction bar 8 is incremented by successively, institute
State heat conduction bar 8 to be connected on the substrate 1 with the larger one end of its radial dimension, the heat of heat conduction bar 8 is from away from substrate 1
End is delivered on substrate 1, therefore the heat that it is transmitted closer to substrate 1 is more, sets the heat conduction bar 8 that radial dimension increases successively
Its heat transfer efficiency is lifted, and it is smaller away from one end size of substrate 1, reduce the influence of its illumination effect to diode chip for backlight unit 3.
