Hereinafter, will describe the present invention in detail.
The electricity-saving lamp 100 of circuit unit of the present invention and lamp body integrated setting is illustrated among Fig. 2, and powerful electricity-saving lamp of the present invention is as can be known seen fully close with the low power electricity-saving lamp profile of prior art from its external perspective view.Electricity-saving lamp 100 of the present invention comprises fluorescent tube 130; Lamp head 120 adopts copper material to make, and is suitable with the lamp socket of conventional, well-known; Inner chamber is moulded housing 140 greater than this head 120, and its lid housing 142 is used for fixing fluorescent tube 130, and fixedlys connected with this lamp head 120 by bottom shell body 144.
Super high power electricity-saving lamp 100 of the present invention is that the control circuit part is arranged in moulding in the housing 140 of lamp body fully, and the decomposing schematic representation of Fig. 3 just has been shown clearly in its inner setting.At first, most of components and parts that electricity-saving lamp 100 of the present invention will constitute the control electronic unit are arranged on the printed circuit board (PCB) 200, and to mould the internal diameter of housing 140 suitable and the circuit element of fixing on it is arranged in the bottom shell body 144 with this for this circuit board 200.This circuit board 200 is provided with one and is used to reduce the humorous temperature rise bill kept on file element module 202 that involves; A control oscillation circuit module 204 consists predominantly of rectifier bridge element 208; Three magnetic ring member L1, L2, L3 (not shown); The transistor T 1 of two symmetric arrangement and T2 (wherein T2 is not shown), this magnetic ring member L1～L3 control this transistor T 1, T2 takes turns conducting and formed oscillating circuit, in order to improve power factor (PF); And one in order to the inductance component L 4 of adjusting the lamp works electric current etc.
If the power of electricity-saving lamp 100 of the present invention can be arranged on more than the 85W at least, the temperature rise that is produced by the luminous of fluorescent tube 130 will reach more than 130 degrees centigrade so.If circuit board 200 long-term works of the present invention in so high temperature environment, very easily by aging, influence its practical life-span; Even also can cause some circuit elements, for example: with the breaking-up of fluorescent tube and the starter polypropylene capacitive element that connects.The fallible component non-refractory because these are heated, the temperature environment that requires is about about 80～85 degrees centigrade usually.Therefore, more particularly, the present invention is provided with this capacitive element C6 stow away from heat, promptly passes the tail end of drain pan spare 144 and is arranged in the lamp holder 120, is electrically connected with circuit board 200 by lead 206.The advantage of Bu Zhiing is can reduce capacitive element C6 on the one hand as much as possible influenced by fluorescent tube 130 temperature rises ground like this, can effectively utilize the space again simultaneously.So this drain pan spare 144 has all installed circuit unit of the present invention with lamp head 120, has formed integrated design.
But in fact, the integrated design structure of the above-mentioned uniqueness of the present invention also is not enough to the temperature rise that isolated fluorescent tube 130 is produced.Because fluorescent tube 130 is directly to be fixed on to cover on the shell spare 142, this has just determined the distance between this fluorescent tube 130 and the control circuit board 200 to be actually very little; Fluorescent tube 130 has most temperature rise and imports in the cavity 140 by lid shell spare 142, and circuit element is within it arranged in influence.Therefore, the present invention is provided with a high temperature resistant heat insulation layer 220 between lid housing 142 and circuit board 200 in moulding cavity 140, and what the present invention adopted is a black high temperature resistant heat insulation plate that about 10mm is thick, can buy on market.In addition, the present invention further is provided with a common thermal insulation layer 222 that gets on this high temperature resistant heat insulation plate 220, and what the present invention adopted is a white thermal insulation board that about 4～6mm is thick, also can buy on market.Simultaneously, can utilize four leads 210 to pass this high temperature resistant heat insulation layer 220 and common thermal insulation layer 222 on this circuit board 200 and cover that lamp tube ends is electrically connected on the shell spare 142 with being fixed on.So just, can completely cut off fluorescent tube 130 temperature well and import in the cavity 140, reduce the temperature rise in this cavity 140 effectively.
