Description
Technical field
The invention belongs to the runners of electronic component parts, particularly a kind of light-emittingdiode.
Background technology
Light-emittingdiode (LIGHT EMITTING DIODE is commonly called as LED) is partly to lead material to make to convert electrical energy into the light-emitting component of luminous energy.Be generally and be fixed in below the metal frame integral body name that metal frame is coated crystalline substance side by semi-conductive crystalline substance side and be defined as solid brilliant thing, and connect outer lead, and comprise the metal frame position in crystalline substance side, formation lenticular outside being coated on transparent resin in metal frame.
Only, the thermal diffusivity of light-emittingdiode is not good.Light-emittingdiode is in order to encase the metal frame of crystalline substance side, and for adopting transparent resin material, right metal frame connects outer lead thereby is conductive metal material.When the heat energy of luminous generation causes metal frame to expand with heat and contract with cold phenomenon, the transparent resin that coats expands with heat and contract with cold degree less than metal frame, allow transparent resin firmly hold onto the metal frame phenomenon of expanding with heat and contract with cold, so that can't allay heat, form heat and concentrate on crystalline substance side, damage crystalline substance side, the useful life of shortening light-emittingdiode.
Summary of the invention
The purpose of this invention is to provide a kind of make easy fast, radiating effect is good, the runners of the light-emittingdiode that increases the service life.
The present invention has end face and a slice side flap corresponding and that extended to form by the end face side at least; End face with at least one first lead foot of runners insulation kenel plug-in mounting; The runners extension is provided with second lead foot.
Wherein:
Four side flaps of end face week side vertical extent formation; But end face and four side flaps are made by conductive material and are and constitute Jiong tee section body.
End face central authorities form inner face and hold groove for the invaginated type of putting several solid brilliant things.
End face differs from all sides of holding groove and is provided with several perforation with respect to the second lead foot direction, and makes one of them perforation adjacent to second lead foot; Compel the dead ring that plug hollow fastens for first lead foot in the perforation; Be connected with conductor wire between first lead foot and the solid brilliant thing.
Side flap near-end end forms several fork longitudinally.
Fork is a long groove shape.
Fork is the slotted hole shape.
End face or end face and part side flap cover cover diffuser.
The prominent bulge loop of establishing of end face; Diffuser is nearly Jiong tee section, and its all side is extended and is provided with so as to being fixed on the sheet that supports on the end face, and is arranged with corresponding and firmly is embedded in the scrobicular ring of end face bulge loop in supporting sheet.
Diffuser forms and is coated on end face and part side flap in the mode of recording transparent resin and extends in fork.
Because the present invention has end face and a slice side flap corresponding and that extended to form by the end face side at least; End face with at least one first lead foot of runners insulation kenel plug-in mounting; The runners extension is provided with second lead foot.It is easy fast to assemble light-emittingdiode manufacturing of the present invention, and increases area of dissipation effectively by the side flap, and the heat energy of luminous generation can conduct to runners by the side flap, significantly to improve the heat sinking function of auxiliary solid brilliant thing, the useful life of the solid brilliant thing of growth.Not only make easy fast, and radiating effect good, increase the service life, thereby reach purpose of the present invention.

Embodiment
As shown in Figure 1, the runners 10 of light-emittingdiode of the present invention has end face 11 that solid brilliant thing 20 is set and at least one, as the side flap 14 that several and end face 11 lateral vertical extend to form, runners 10 end faces with at least one first lead foot 15 of its insulated type plug-in mounting in order to be electrically connected; Runners 10 extends second lead foot 16 that is provided with in order to be electrically connected.
As Fig. 1, Fig. 2, shown in Figure 3, conductive material is made and is the Jiong tee section but runners 10 is served as reasons, and it is bent to form side flap 14 formation that all sides are extended for the end face 11 with the corresponding central authorities of crosswise lamellar body towards the side direction one.
Whether each side flap 14 near-end end forms several fork 141 longitudinally, and fork 141 can be long groove shape or slotted hole shape, and extend second lead foot 16, the second lead foots 16 relative with first lead foot 15 in a side flap 14 wherein by the root edge one and bend all unrestricted.The first lead foot seat, 10 insulation of second lead foot 16 and runners 10 allow first and second lead foot 15,16 form the effect of cathode and anode, and are connected with conductor wire 21 between solid brilliant thing 20 and first lead foot 15, just can form electronic loop after runners 10 connecting circuits.
As Fig. 4, Fig. 5, shown in Figure 6, also can cover diffuser 40 in end face 11 covers of runners 10.
The end face 11 prominent bulge loops of establishing.
Diffuser 40 is nearly Jiong tee section, and its all side is extended to be provided with so as to being fixed on and supported sheet 42 on the end face 11, and is arranged with corresponding and firmly is embedded in the scrobicular ring of end face 11 bulge loops in supporting sheet 42.
Therefore, after first and second lead foot 15,16 is electrically connected on circuit board, just can forms electronic loop, and be converted to luminous energy, produce illumination effect with crystalline substance side with the extremely solid brilliant thing 20 of conduct electrical energy through energising.
As shown in Figure 7, diffuser 45 forms and is coated on the position of runners 10 and part side flap 14 in the mode of recording transparent resin, and diffuser 45 coating scopes extend to fork 141 parts in side flap 14, see through slotted hole or elongated slot kenel that fork 141 forms, make resin have firm chimeric slip-off preventing effect.
Therefore, the design of the runners 10 of light-emittingdiode of the present invention is selected for use the diffuser 40,45 of different kenels.
In addition, the runners 10 of light-emittingdiode of the present invention, can allow first lead foot 15 form in runners 10 in the efficient mode of rule, as be set as two row sheet metals, above one row sheet metal form several at interval to first lead foot 15, below one row sheet metal form several first lead foots 15 at interval, allow runners 10 between two row's sheet metals, allow runners 10 1 sides form two perforation 13 and aim at the row of going up, opposite side forms perforation 130 and aims at row down, simultaneously first lead foot 15 of all directions is planted synchronously on runners 10 again, simplify and quicken processing procedure.
As mentioned above, the present invention has following special efficacy:
1, heat sinking function excellence: the present invention sees through the side flap increases area of dissipation effectively, so as to thermal energy conduction to runners, significantly to improve the heat sinking function of auxiliary solid brilliant thing, increase the useful life of solid brilliant thing.
2, the present invention is with the locate mode of diffuser cover cap in end face, or selecting to record the transparent resin form forms diffuser, in order to do selecting for use speed soon, the mode of recording is come processing and manufacturing cheaply for the manufacturer, diffuser is shaped as the moulding that can increase its variation arbitrarily; Even if diffuser coats runners, also still can increase area of dissipation by the side flap, make the present invention have multiple advantages such as manufacturing speed is fast, heat radiation is good, diffuser variable shaping concurrently.The present invention can produce DIP or SMD according to need.
