Background technology
Because LED produces luminous energy and heat energy luminous time, and if the heat energy producing can not effectively leave, can be because of excess Temperature, cause LED chip to damage, and then LED bulb lost efficacy.Existing LED bulb, be all by LED lamp pearl paster to aluminium base, then aluminium base is fixed on radiator and is dispelled the heat.Present radiator is to be all made by various Heat Conduction Materials, is arranged on lamp holder top inner chamber, and pearl is contained in lampshade by support LED lamp.Existing LED bulb, compared with traditional osram lamp, because radiator shell has occupied most of space of bulb inner chamber, cause light-emitting area too little, also disunity of the size of bulb, make it as traditional osram lamp, to be applicable to all occasions, can not replace fully and effectively traditional osram lamp.More existing LED lamp bulbs, in order to pursue simply size and the profile the same with conventional bulb, still but can not solve the heat dissipation problem of LED chip effectively, cause the life-span of LED bulb not long.
Summary of the invention
The object of the present invention is to provide a kind of LED bulb, this LED lamp bulb radiating structure is very simple, radiating effect is remarkable, can improve widely its service life; The upper and lower position of the LED light source plate of this LED bulb in lampshade can regulate arbitrarily, can adapt to the demand of difform lampshade, improved versatility and the standardization level of product.
Technical solution proposed by the invention is such:
A kind of LED bulb, comprise lamp holder 1, LED driving power 2, LED light source plate 4 and lampshade 5, LED driving power 2 inputs are connected with the external AC utmost point of lamp holder 1 by wire, also be provided with two-stage cylinder type radiator 3, first grade of this radiator 3 is cylindrical, be provided with two draw-in grooves that are parallel to each other 31 and a long through groove 32 in the upper surface 35 of radiator 3, plane LED light source plate 4 bottom surfaces are close on upper surface 35 and by two clamp bar slots 31 and tighten up, the set wiring board 21 of LED driving power 2 being placed in radiator 3 inner chambers stretches out and is electrically connected with the power input of LED light source plate 4 from dead slot 32, second level of described radiator 3 is screw thread cylindrical shell 34, the screw thread of this screw thread cylindrical shell 34 mates and is threaded with the screw thread of described lamp holder 1, described lamp holder 1 upper inner, the chimeric gluing connection mutually of screw thread cylindrical shell 34 tops of radiator 3 and lampshade 5 lower bottom parts.
Described two-stage cylinder type radiator 3 adopts conductive metallic material punching stretch to form.34 times bottom side of screw thread cylindrical shell at described two-stage cylinder type radiator 3 are provided with facet 33.LED light source plate 4 is provided with two point source input endpoints, and the wiring board 21 of LED driving power 2 stretches out to be provided with two power inputs of LED light source plate 4 from dead slot 32 puts 2 liang of outputs of corresponding LED driving power, and connects by soldering.Described lampshade 5 be shaped as spherical or hemispherical or pyriform or cylindricality.Described lamp holder 1 is E27 or E14.
Compared with prior art, the present invention has following remarkable result:
Key technology of the present invention is to have designed a two-stage cylinder type radiator, the screw thread of its second grade of screw thread cylindrical shell mates and is threaded with the screw thread of lamp holder, LED light source plate can be fastened on to smooth docile on radiator upper surface, and by whole radiator and lamp holder outwards heat radiation in large area, thereby, the radiating effect of LED chip is remarkable especially, and LED driving power is placed on radiator inner chamber and also its heat radiation is brought about tangible results.In addition, the radiator structure of this LED bulb is very simple, and it is very convenient to assemble, and production efficiency is high, has reduced production cost.Due to radiator and lamp holder employing screw connection structure, thereby, the LED light source plate that is positioned at radiator upper end can regulate continuously in the upright position of lampshade, can adapt to the lampshade of different profiles, as the requirement of the lampshades such as spherical, pyriform, cylindricality to cover inner light source point position, meanwhile, product versatility and standardization level have also been improved.Because the face shaping of this LED lamp bulb and traditional osram lamp are consistent, thus traditional osram lamp can be substituted completely, but energy-conservation widely.
