The illuminating diode 121 has a heat conducting plate 131 adjacent to the aluminum substrate 111, a heat conducting surrounding wall 132 connecting the outer periphery of the heat conducting plate 131, and a heat conducting surrounding wall 132 disposed in the heat conducting surrounding wall 132. a soft layer 133 disposed on a side of the heat conducting plate 131 opposite to the aluminum substrate 111, and a heat conducting space 134 defined by the heat conducting surrounding wall 132 and the soft layer 133.

使用時,該第二電壓模組113可將交流電壓220V轉換成交流電壓110V,該第一電壓模組112再將交流電壓110V轉換成驅使該等發光二極體121發光的直流電壓,進而使該LED燈泡發光,而該等發光二極體121產生的熱量會經由該鋁基板111及該導熱板131後,最後由該導熱圍壁132將熱量散逸至該導熱空間134,而達到散熱的效果。In use, the second voltage module 113 converts the AC voltage 220V into an AC voltage of 110V, and the first voltage module 112 converts the AC voltage 110V into a DC voltage that drives the LEDs 121 to emit light, thereby The LED light bulb emits light, and the heat generated by the light-emitting diodes 121 passes through the aluminum substrate 111 and the heat-conducting plate 131, and finally the heat-dissipating wall 132 dissipates heat to the heat-conducting space 134 to achieve heat dissipation. .
然而,由於該等發光二極體121產生的熱量也會經由該鋁基板111而使該第一電壓模組112處於高溫環境,因此在長期使用下,該第一電壓模組112容易因積熱過高而損壞,因此進一步改良散熱方式是目前仍然在發展中的技術。However, since the heat generated by the light-emitting diodes 121 also causes the first voltage module 112 to be in a high-temperature environment via the aluminum substrate 111, the first voltage module 112 is prone to heat accumulation due to long-term use.

In the embodiment, the positioning holes 51 are located on the aluminum substrate 22 , and the positioning posts 52 are disposed on the heat conducting plate 411 .
該燈罩6自該第一表面231外側蓋設於該殼體42。The lamp cover 6 is covered by the casing 42 from the outside of the first surface 231 .
使用時,是以該插頭件26插設於一燈座(圖未示),當該燈座所提供的交流電壓為100V~240V時,該第一電壓模組24及該第二電壓模組25將交流電壓轉換為直流電壓以驅使該等發光二極體31發光。In use, the plug member 26 is inserted into a lamp holder (not shown). When the AC voltage provided by the lamp holder is 100V~240V, the first voltage module 24 and the second voltage module are used. 25 converts the alternating voltage into a direct current voltage to drive the light emitting diodes 31 to emit light.
此時,該等發光二極體31在運作時所產生的熱量會由該鋁基板22依序傳導至該導熱板411及該導熱圍壁412,除了會由該導熱圍壁412負責將熱量同時散逸於該導熱空間413中及透過該殼體42傳導至外部,該導熱板411由於直接相鄰該導熱空間413,因此也能夠用於將熱量散逸於該導熱空間413中,由於該導熱板411及該導熱圍壁412皆相鄰該導熱空間413,且該導熱圍壁412還相鄰可導熱的該殼體42,因此散熱效果較佳。At this time, the heat generated by the LEDs 31 during operation is sequentially transmitted from the aluminum substrate 22 to the heat conducting plate 411 and the heat conducting wall 412, except that the heat conducting wall 412 is responsible for transferring heat simultaneously. Dissipating in the heat conducting space 413 and conducting to the outside through the housing 42. The heat conducting plate 411 can also be used to dissipate heat in the heat conducting space 413 due to being directly adjacent to the heat conducting space 413, since the heat conducting plate 411 The heat conducting surrounding wall 412 is adjacent to the heat conducting space 413, and the heat conducting surrounding wall 412 is adjacent to the heat conductive housing 42, so that the heat dissipation effect is better.
由於該等發光二極體31的散熱效果很好,因此環繞該阻熱板21外周緣的該鋁基板22不會將熱量傳遞至位於中間的該阻熱板21,而能避免位於該鋁基板22中央的該第一電壓模組24及該第二電壓模組25受到該等發光二極體31的高熱影響而導致容易損壞的問題,進而提升使用壽命,並節省花費。Since the heat dissipation effect of the light emitting diodes 31 is good, the aluminum substrate 22 surrounding the outer periphery of the heat blocking plate 21 does not transfer heat to the heat blocking plate 21 located in the middle, and can avoid being located on the aluminum substrate. The first voltage module 24 and the second voltage module 25 in the center are affected by the high heat of the light-emitting diodes 31, thereby causing the problem of easy damage, thereby improving the service life and saving the cost.
綜上所述,藉由該第一電壓模組24及該第二電壓模組25分別設置於該第一表面231及該第二表面211,並使該等發光二極體31所產生的熱量,能直接經由該鋁基板22而通過該導熱板411及該導熱圍壁412,不會向內積熱於該阻熱板21,而能提高散熱效果,以及提高使用壽命,故確實能達成本發明之目的。In summary, the first voltage module 24 and the second voltage module 25 are respectively disposed on the first surface 231 and the second surface 211, and the heat generated by the LEDs 31 is generated. The heat conducting plate 411 and the heat conducting surrounding wall 412 can pass through the aluminum substrate 22 without accumulating heat to the heat blocking plate 21, thereby improving the heat dissipation effect and improving the service life. The purpose of the invention.
