[0026] 请参考图2至图4,该反射单元70包括一反射套74和两个反射板72、76,其中:该反射套74套设于该传热柱60之外;该反射板72贴设于该基板40的固定面44之上,为了配合该十二个LED光源50,该反射板72之上对应该些LED光源50的位置设有十二个让位孔(说明书附图中未绘示),该LED光源50固定于该让位孔之内,露出于该让位孔并与该反射板72的表面齐平或者稍高,以免挡住其所发出的光;该反射板76贴设于该散热器20顶部的端面上,该反射板72和该反射板76相对设置,而反射套74连接于该两个反射板72、76 之间。 [0026] Please refer to FIG. 2 to FIG. 4, the reflecting unit 70 includes a reflector 74 and two sets of reflector plates 72, 76, wherein: the reflection case 74 is sleeved outside of the heat transfer column 60; reflective plate 72 stickers provided on the fixing surface 44 on the substrate 40, in order to meet the twelve LED light source 50, the reflecting plate 72 is provided above the position of twelve holes should give way some of the LED light source 50 (in the accompanying drawings not shown) of the LED light source 50 is fixed inside the bore of giving way, give way to the aperture and is exposed flush with or slightly higher than the surface of the reflecting plate 72, so as not to block the light emitted from it; the reflecting plate 76 affixed to the end face disposed on the top of the heat sink 20, and the reflective plate 72 disposed opposite the reflecting plate 76, and the reflective sleeve 74 is connected between the two reflecting plates 72, 76.

[0027] 该LED大角度照明灯100工作时,位于该基板40的固定面42上的LED光源50通电发光,该些LED光源50对应该灯泡壳30的顶罩32,其所发出的光线将照射于该顶罩32 上,由于顶罩32上设有透光散射材料,因此顶罩32上的光线分布均勻。 [0027] 100 operates when the wide-angle LED lighting, the substrate fixing surface 40 is located at the LED light source 50 is energized on the light emitting 42, 50 pairs of the plurality of LED light sources should the lamp bulb 32 of the top cover 30, the light emitted from it It is irradiated to the top cover 32, since the top cover 32 is provided on the light-transmissive scattering material, thus the top cover 32 on the light distribution. 位于该基板40的固定面44上的LED光源50所发出的光线向下发散,照射至该底罩36的下方、反射套72上和贴设于散热器20上的反射板76之上,该反射套72将光线反射至底罩36的侧面,而该反射板76不仅将光线反射至底罩36侧面,还向上反射至其对应的反射板74上,然后该反射板74又将光线向下反射,因此使得该底罩36的下方也有较强的光线分布,增大了本LED灯100的发光角度,由于底罩36上设有透光散射材料,因此底罩36侧面的光线分布均勻。 The substrate 40 is positioned light LED 44 is fixed on the surface light source 50 is emitted downwardly diverging, is irradiated to downward of the bottom cover 36, sleeve 72 and reflected on the reflecting plate 76 is provided attached on the heat sink 20, the reflected light beam to the sleeve 72 cover a bottom side 36 and the reflecting plate 76 side surface 36 will not reflect light to the bottom cover, further reflection upwardly to its corresponding reflection plate 74, the reflective plate 74 and then turn downwards the light reflection, so that the bottom of the bottom cover 36 also has a strong light distribution, increasing the angle of emission of this LED lamp 100, since the scattered light transmissive material 36 on the bottom cover, the bottom cover so uniform light distribution in the side surface 36. 由于顶罩32和底罩36上都设有透光散射材料,因此虽然本实施例中的散热环34为不透明的铝件,却不会遮光,该LED光源50发光时,光线仍可在该顶罩32和底罩36上的透光散射材料的作用下向四面八方照射,如光线由顶罩32向下发射,也由底罩36向上发射,从远处看, 光线并未被该散热环;34遮挡住。 Since the top cover 32 and bottom cover 36 has a translucent scattering material, while the present embodiment of the cooling ring 34 embodiment is opaque aluminum, but not the light-shielding, the LED light source 50 to emit light, the light can still irradiating in all directions under the action of the top cover 32 and the light-permeable diffusive material on the bottom cover 36, as the light emitted downwardly from the top cover 32, bottom cover 36 is also emitted by the upwardly from a distance, the light that has not been heat ring ; 34 blocking. 这样,该LED大角度照明灯100的发光角度可达美国能源之星标准的沘0°至320°。 Thus, the light emitting angle of the wide-angle LED lighting up lamp 100 US Energy Star standard Bi 0 ° to 320 °.

[0028] 由于散热环34与基板40为一体成型,基板40、传热柱60和散热器20热连接,因此LED灯100通电发光时,基板40上的LED光源50产生的热量不仅依次通过基板40、传热柱60传递至散热器20,再由散热器20向外界空气散热,还通过基板40传递至散热环34,再由散热环34向外界空气散热;由于散热环34的设置,增大了LED灯100的散热面积,与传统的灯具只利用散热器来散热的散热方式相比,散热效率更高,有利于延长灯具使用寿命。 [0028] Since the heat ring 34 is integrally formed with the substrate 40, 40, 60 and the heat transfer columns substrate 20 is thermally connected to the heat sink, so the LED lamp 100 is energized to emit light, heat generated by the LED light source 50 on the substrate 40 only passes through the substrate 40, the heat transfer column 60 is transmitted to the radiator 20, the radiator 20 and then heat to the outside air, passing through the substrate 40 to the heat ring 34, the ring 34 and then by heat dissipation to the outside air; since the heat ring 34, by large cooling area of ​​the LED lamp 100, the conventional lamp cooling method using only heat radiator as compared to higher heat dissipation efficiency, help to extend the lamp life.

[0029] 综上所述,本发明的本发明LED大角度照明灯100通过在该灯泡壳30内设置该基板40,将这些LED光源50分别设于基板40的两个固定面42、44上,使得该LED大角度照明灯100能够实现大角度照明;通过将该基板40与该灯泡壳30热连接,可以有效地将这些LED光源50发出的热量传递至该灯泡壳30上,并通过该灯泡壳30散发出去。 [0029] In summary, the present invention to large-angle LED lighting lamp 100 through the substrate 40 disposed within the lamp bulb 30, these LED light sources 50 are provided on the two fixed surfaces 42, 44 on the substrate 40 , so that the large-angle LED lighting lamp 100 can achieve a large angle illumination; bulb 40 is connected to the housing 30 by the heat of the substrate, the heat can be efficiently emitted from the LED light source 50 is transmitted to the lamp bulb 30, and through the lamp housing 30 to dissipate. 这就使得本发明LED大角度照明灯100相比现有技术具有更大的散热面积,从而具有散热效率较高的优点。 This makes wide-angle LED of the present invention over the prior art lamp 100 having a larger heat dissipation area, thereby having the advantage of high heat dissipation efficiency.
