Detailed description of the invention

[0043] for setting forth further patent of the present invention for the technological means reaching predetermined object and take and effect, below in conjunction with accompanying drawing, to the bulb type LED proposed according to patent of the present invention, its detailed description of the invention, structure, feature and effect thereof, be described in detail as follows.

[0044] as shown in Figures 1 to 8, 1 is LED bulb, this bulb 1 comprises: aluminium alloy heat radiation base portion 12, be arranged on the LED module 11 of this heat radiation base portion 12 1 lateral edges (lateral edges of the lamp axle of LED bulb 1), be arranged on the resin enclosure 13 that this heat radiation base portion 12 opposite side edge has insulating properties, be arranged on the lamp holder 14(E26 of the opposite side of this insulating resin shell, E27), cover LED module 11 and be arranged on the translucent cover 15 with light diffusion function of heat radiation base portion 12 1 lateral edges, be arranged on the reflector 16 between translucent cover 15 and heat radiation base portion 12, and the driving power 17 be accommodated between heat radiation base portion 12 and lamp holder 14 in insulating resin shell 13.

[0045] base portion 12 that dispels the heat is cast into one by the Al-alloy metal that heat conductivility is splendid, middle body is the thermal interface 121a 121b installing LED module 11, some built-in radiating fins 122 are uniformly distributed in its surrounding, the heat conduction of LED module 11 is extremely dispelled the heat in the smooth outer surface of base portion 12 simultaneously, and the hollow space 123c that the ventilating opening 123a of extraneous air through base portion one end of dispelling the heat is formed by built-in fin 122 and heat radiation base portion 12 shell flows out other end ventilating opening 123b, LED bulb 1 inside is made to form funnel-shaped cross-ventilation.

[0046] a lateral edges of built-in fin 122 be formed cylindric and solid in trunk 126, form level and smooth outer trunk 127 at opposite side edge.

[0047] 121a on the face of a lateral edges of heat radiation base portion 12, fits with LED module 11 installed surface, forms thermal interface, and form a power line via hole 124 of 3 fixed screw holes 125 and central authorities at this installed surface 121a.Form the groove of a circle surrounding for installing translucent cover 15 at edge one lateral edges of heat radiation base portion 12, and the side, edge of translucent cover 15 is formed with several outstanding boss.

[0048] dispel the heat base portion 12 have central authorities thermal interface 121a and 121b thickness maximum, trend outwards thinning gradually successively, namely have the thermal capacity of central trunk 126 to be greater than built-in fin 122, and built-in fin 122 thermal capacity is greater than the thermal capacity of the outer trunk 127 of heat radiation base portion 12.

[0049] LED module 11, it has the circular substrate 111 that the materials such as the metal materials such as aluminium, pottery or epoxy resin are formed, and the side as this substrate 111 is configured with line pattern and several LED light-emitting components 112 of circular array surface mount.Several LED element 112 form connection in series-parallel by Wiring pattern, and are electrically connected with driving power 17 by pad.

[0050] forming 3 screw installing holes 113 in four circumferences of circular substrate 111, dispelling the heat on the thermal interface 121a of base portion 12 by being connected substrate 111 to be fixed on by screw machine with the screw hole 133 on insulating resin shell 13.

[0051] reflector 16 is by insulation high-temperature-resistant material ejection formations such as Merlon (PC) or polybutylene terephthalate (PBT) (PBT) resins, white and there is best bright finish, reflector 16 1 lateral edges is fitted in LED module 11 edge, and opposite side edge is fixed by the edge button bit of translucent cover 15 with heat radiation base portion 12.Reflector 16 effectively collects the light reflected by light diffusion translucent cover 15 that LED light-emitting component 112 sends and again to reflex to translucent cover 15 outside.

[0052] insulating resin shell 13 is by insulation high-temperature-resistant material ejection formations such as Merlon (PC) or polybutylene terephthalate (PBT) (PBT) resins, side rim openings also evenly forms the screw hole 133 of 3 columns and coaxial with the screw hole 125 of the thermal interface 121a of the screw installing hole 113 on substrate 111 and the base portion 12 that dispels the heat in surrounding, evenly form 4 ventilating openings 131 between opposite side edge and lamp holder 14, and be mechanically connected with lamp holder 14.

[0053] lamp holder 14, can be connected to the lamp for general lighting seat of E26 or E27 shape etc., and it is fitted together to insulating resin shell 13 and rivets fixing, and is electrically connected with driving power 17.

[0054] translucent cover 15, by having resin that light spreads or the thin-walled dome shape that glass etc. is formed in the mode covering LED illuminating module 11, the side rim openings of translucent cover, and formed several boss be arranged on heat radiation base portion 12 button bit place, edge and add coating adhesive.

[0055] driving power 17, the LED light-emitting component 112 had for LED illuminating module 11 provides the power supply of constant current, and there is the circuit base plate of the multiple electronic devices and components being installed with forming circuit, this substrate reception is in insulating resin shell 13, lamp holder 14 is electrically connected at the input of driving power 17 by connecting line, the output of driving power is electrically connected in LED-baseplate 111.

[0056] heat produced after lighting the LED light-emitting component 112 of LED module 11 conducts to the thermal interface 121a 121b of heat radiation base portion 12 from LED-baseplate 111, conduct heat to central trunk 126 again, conducted to the outer trunk 127 of heat radiation base portion 12 by built-in fin 122, and then conduct to efficiently in air.

[0057] simultaneously, heat is conducted to the edge of heat radiation base portion 12 by built-in fin 122, because edge wall thickness is large compared with thick event thermal capacity, can receives the heat of fin 122 fast and conduct in air.

[0058] built-in fin 122 to heat radiation base portion 12 outer trunk 127 heat conduction while, the hollow space 123c that the ventilating opening 123a of extraneous air through base portion 12 one end of dispelling the heat is formed by built-in fin 122 and the outer trunk 127 of heat radiation base portion 12 flows out other end ventilating opening 123b, makes LED bulb 1 inside form funnel-shaped forced convertion thus effectively suppress the temperature rise of LED light-emitting component 112.

[0059] the above, only the better enforcement case row of patent of the present invention, not any pro forma restriction is done to patent of the present invention, although patent of the present invention discloses with preferred embodiment, but be not intended to limit patent of the present invention, any those skilled in the art, not departing from the technical program, do a little change when the content of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from art solutions content of the present invention, according to any simple modification that the technical spirit of patent of the present invention is done above embodiment, equivalent variations and modification, all still belong within the scope of art solutions of the present invention.
