Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, 2, 3, the LED package 1 of present embodiment comprises light-emitting diode chip for backlight unit 100, support 200 and mould 300.Wherein: light-emitting diode chip for backlight unit 100 is engaged with N type semiconductor by P type semiconductor and forms, and produces light during from P type semiconductor to the N type semiconductor current emission; Support 200 comprises isolates first lead division 210 and second lead division 220 that is provided with.
There is individual concave part 214 middle part of support 200, and as shown in Figure 2, first lead division 210 is toward the recessed part of downside, and light-emitting diode chip for backlight unit 100 is installed in the concave part 214.In the present embodiment, the anode of light-emitting diode chip for backlight unit 100 and negative electrode correspond respectively to first lead division 210 and second lead division 220, somely in the anode of light-emitting diode chip for backlight unit 100 or the negative electrode lead to first lead division, 210, the first lead divisions, 210 terminals by a lead 410 and form the portion of terminal 212 be connected with external circuitry; Light-emitting diode chip for backlight unit 100 another utmost points lead to second lead division 220 by an other lead 420, second lead division, 220 terminals form the portion of terminal 222 that is connected with external circuitry, because first lead division 210 and second lead division, 220 physical properties are isolated mutually, the anode of light-emitting diode chip for backlight unit 100 electrically separates with negative electrode.
First lead division 210 and the 220 isolated settings of second lead division form spacing 215,216 between first lead division 210 and second lead division 220.Width d1, the d3 at these spacing 215,216 two ends on its bearing of trend is greater than the width d2 in the middle of it.The shape of spacing 215,216 is centrosymmetric images, promptly from both ends to the middle awl (taper) is formed, and in other words, the shape of spacing 215,216 is to reduce gradually from both ends to the middle.As shown in Figure 3, the width at spacing 215 two ends is wideer than the centre, and the axis of symmetry of its bearing of trend also forms symmetry, and past more centre is narrow more; As shown in Figure 4, spacing 215 different its forms that are in spacing 216 and Fig. 3 are similar to curve.
Mould 300 is fixed mutually after support 200 fixed installations.The portion of terminal 212 of first lead division 210 and the portion of terminal 222 of second lead division 220 are exposed from mould 300 two ends.Shown in Fig. 5,6, mould 300 has filling part 310, and filling part 310 is filled in the spacing 215,216 between first lead division 210 and second lead division 220.
The heat of sending on the light-emitting diode chip for backlight unit 100 effectively sheds at the concave part 214 by first lead division 210.Mould 300 is the material of thermosetting resin (epoxy molding compound), and in order better to accomplish the light reflection, thermosetting resin interpolation silicon silica etc. makes it present white; Simultaneously, make the effect of LED package reach best at the light-emitting diode chip for backlight unit 100 coated resins of fluorescent material that comprise.
The mould of the LED package 2 of present embodiment is that the white hot hardening resin is by compression forming, the thermosetting resin thermal endurance is more outstanding, adherence force to support 200 is also stronger, and, mould compared with the PPA material, light-emitting diode chip for backlight unit 100 heatings can be out of shape yet, and adherence force also can continue to keep, and significantly promotes 1 reliability effect of LED package; And the mould 200 that thermosetting resin forms can more effective inhibition to the effect of resin loss than the mould of PPA resin forming.
Yet thermosetting resin is more more outstanding than thermoplastic resin PPA heat-resistant quality and adherence force etc., but also bigger than PPA hardness, and therefore damaged equally likely possibility is also high more.Width by spacing in the present embodiment diminishes from both ends to the middle gradually, suppresses the stress concentration phenomenon, makes the possibility of filling part 310 breakages of mould 200 littler.In addition, the width of spacing directly influences filling part 310 and first lead division 210, second lead division, 220 bonding areas under a stable condition, to reach filling part 310 and first lead division 210, second lead division 220 are pasted more firm.
Shown in Fig. 5,6, in the present embodiment, the filling part 310 of mould 200 extends upward reinforcement part 320, and reinforcement part 320 is protruding gradually to two ends from the centre of filling part 310, and the thickness of mould 200 is thicker than the madial wall between filling part 310 both sides.Because reinforcement part 320 forms with outstanding form on filling part 310, bear together reinforcement part 320 when filling part 310 is stressed, in addition, compared with filling part 310 inboards, filling part 310 both sides are higher with the possibility that be full of cracks takes place because of external impact, so reinforcement part 320 is in filling part 310 both sides projectioies.
In addition, reinforcement part 320 is higher than the installation site of first lead division 210 and second lead division 220, exists with discontiguous form.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the present utility model.
