Its two, as Fig. 2, mainly comprise lamp holder 10 ', lamp housing 20 ', power supply 30 ', LED light-emitting component 40 ' and cell-shell 50 '; Lamp housing 20 ' comprises metal heat conducting-body 201 ' and is coated on the insulation shell 202 ' of metal heat-conducting surface, lamp housing upper portion insulating shell rivething lamp holder, lamp housing bottom insulation shell connects cell-shell, and lamp housing lower metal heat carrier arranges the multi-faceted column 60 ' of one and lamp holder axis coaxle.As Fig. 3, a kind of structure is LED light-emitting component aluminium base 601 ' is laminated structure, the multi-faceted column side of every sheet LED light-emitting component and lamp housing lower metal heat carrier 201 ' and end face is corresponding connects, the Light distribation requirement of omnirange lamp is met by the lamp pearl quantity arranged on each face, but the electric connection structure between every sheet LED light-emitting component is complicated, and manufacturing cost is high; As Fig. 4 and Fig. 5, another kind of structure is LED light emitting element substrate is flexible base board 602 ', although this structure solves the complicated problem of above-mentioned multi-piece substrate electrical connection, luminous flux loss is few, and light efficiency is high, and flexible base board cost is more a lot of than aluminium base plate hight.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of electric connection structure, the pyramidal structure omnirange LEDbulb lamp of the aluminum substrate structure that cost is low.
A kind of pyramidal structure omnirange LED of the present invention, comprises lamp holder, lamp housing, power supply, LED light-emitting component, electrical connection pcb board and cell-shell; Lamp housing comprises metal heat conducting-body and is coated on the insulation shell of metal heat-conducting surface, cell-shell is connected with the insulation shell of lamp housing bottom, be electrically connected between lamp holder, power supply, electrical connection pcb board, LED light-emitting component, it is characterized in that: metal heat conducting-body top arranges a cylindrical section, bottom arranges a polyhedral cone body, and the aluminium base of LED light-emitting component is strip; The cylinder on metal heat conducting-body top is connected with lamp holder, and bar-shaped LED light-emitting component correspondence is fixed in each plane of bullet, and the electrode of every bar aluminium base is arranged on the vertex of a cone direction of bullet, and the pad correspondence of electrical connection pcb board connects the electrode of every bar aluminium base.
The coning angle of described polyhedral cone body is 25 to 50 degree.
Described bar-shaped LED light-emitting component is secured in each plane of bullet by tight loop.
A kind of pyramidal structure omnirange LEDbulb lamp advantage of the present invention:
1. compared with the prior art of lamp housing upper portion insulating shell rivething lamp holder, because the cylinder of the metal heat conducting-body upper end in radiator of the present invention and lamp holder are riveted fixing, the heat of LED light-emitting component can be directly transferred to base surface by metal heat conducting-body, which increases the cooling surface area of LED, higher light output can be obtained under identical light-emitting component, or under identical light output condition, the lamp pearl quantity in light-emitting component can be reduced, save cost.
2. because metal heat conducting-body bottom arranges a polyhedral cone body, bar-shaped LED light-emitting component is fixed in each plane of bullet by tight loop correspondence, the electrode of every bar aluminium base of bar-shaped LED light-emitting component is arranged on the vertex of a cone direction of bullet, the pad correspondence of electrical connection pcb board connects the electrode of every bar aluminium base, therefore, the aluminium base fixed form of bar-shaped LED light-emitting component is simple, and efficiency of assembling is high; Electrical connection pcb board pad and LED light-emitting element electrode can adopt immersed solder, and technique is simple, and welding efficiency is high, and cost is low.
3., because the change of the angle of taper by changing polyhedral cone body can change the distribution of light at 0-135 degree, require ratio with the existing Light distribation meeting omnirange lamp by the lamp pearl quantity be arranged on column side face and end face, structure is simple.
