Description

A kind of plug-in unit LED contact pins pin inserted insulation heat dissipating method and device
Technical field
The invention belongs to technical field of LED illumination, and in particular to the insulation of the lighting module being made up of plug-in unit LED lamp bead dissipates Thermal means and device.
Background technology
Basic luminescence component-LED the modules of current Modular LED lamp, are generally mounted on using adopting surface mounted LED lamp bead Copper aluminium base is covered, being used as heat-conduction medium by heat-conducting silicone grease is contacted with metal heat sink, the heat produced during by LED lamp bead burning-point Amount is conducted to radiator, by the outside function of environment heat emission of radiator.And it is universal in the manufacture of LED modules using plug-in type LED lamp bead Less, its problem is that plug-in type LED lamp bead cannot carry out covering copper aluminium base note dress, can only be carried out using glass printed circuit board (PCB) Inserting, circuit board bottom surface carries stitch and bag-like bump after inserting, and stitch and bump are with low tension and into loop, it is impossible to Directly with metal class radiator directly contact.Because stitch and the convex end of bump are needle point state, glass printing electricity Road plate bottom surface is not burnishing surface, using brushing heat-conducting silicone grease for the method for heat-conducting medium cannot be formed effectively with stitch and bump Thermal conductive contact area, heat-conducting effect is poor.
It is existing to increase using stacking heat-conducting silicone grease and between stitch and bump and metal heat sink one for problem above The method of the thin micarex of piece is come using plug-in type LED lamp bead manufacture LED modules, the document delivered mainly includes《One kind is based on small The LED street lamp of power ellipse lamp bead》Utility model patent notification number CN205424589U, patent of invention publication No. CN105156955A;《A kind of LED street lamp》Use new patent notification number CN203349111U.This kind of method is needed in glass print Printed circuit board bottom surface first stacks certain thickness heat-conducting silicone grease, and stitch and scolding tin point boss are all covered, and its thickness is general 2 To 2.5 millimeters;Then at one layer of thin heat-conducting silicone grease of metal heat sink heat-transfer area brushing;Thin micarex is affixed on metal heat sink heat transfer Face;Then at one layer of thin heat-conducting silicone grease of mica plate face brushing;The glass printed circuit board (PCB) for stacking heat-conducting silicone grease is finally affixed on mica Plate face is fixed.
The deficiency of this kind of method is to be provided with thin micarex for exhausted between stitch and bump and metal heat sink Edge, micarex is mainly included in so insulation but low thermal conductivity, only 0.4W/mK, the document of reference《Insulating materials》On deliver 's《The research of Thermal Conductivity of Mica Tape Adhesive》;Its physical state is hard sheet, and gap filling ability is poor, is focusing on radiating This micarex is set in LED modules, the heat conduction continuity of heat-conducting system is hindered, the thermal resistance of LED modules is increased.Heat-conducting silicone grease In emulsus and with mobility, preferable calking effect is not reached yet when glass printed circuit board (PCB) bottom surface stacks, it is impossible to formed Effective thermal conductive contact area, separates out with after volatilization after silicone oil, and the practical function of heat-conducting silicone grease can decay seriously.In glass printing When circuit board is affixed on the fixation of mica plate face, LED stitch easily pierces through thin micarex and causes LED lamp bead stitch directly and metal heat sink Contact formed electric leakage, cause LED modules cannot burning-point use.Its complex manufacturing of LED modules and difficulty are manufactured using the method With the quality control being standardized.
LED modules prepared by method described above are applied to LED lamp and there is following common fault:Circuit board bottom surface pins pierced cloud Motherboard contacts with metal heat sink and is also easy to produce leaky and causes light fixture yield rate low, using dangerous;LED module system thermal resistances Greatly, heat-conducting effect is poor, easily causes the excessive light decay of LED lamp bead or even causes LED lamp bead to fail because heat conduction is bad;In heat-conducting silicone grease Silicone oil can separate out or be affected by gravity outflow, cause heat-conducting silicone grease to harden, infilling lose, lose heat-conducting effect.
