有鑑於發光二極體(LED)具有體積小、發光效率佳以及使用壽命長等等特點,市面上已漸漸出現以LED元件作為光源的LED燈管。In view of the fact that the light-emitting diode (LED) has the characteristics of small volume, good luminous efficiency and long service life, LED lamps with LED elements as light sources have gradually appeared on the market.
請參閱圖18所示,既有LED燈管包含有一散熱座60、一LED燈板70、一管罩80及二燈帽90;該散熱座60係呈半圓柱形,其圓弧一面向平坦一面凹陷成形有複數散熱鰭片61,該散熱座60平坦一面與半圓柱軸向方向平行的二相對側邊分別具有一滑槽62;該LED燈板70係設置該散熱座60上且接觸於該散熱座60平坦一面並具有複數LED元件72,該LED燈板70係滑設於該散熱座60之滑槽62且該LED燈板70端部與該散熱座60齊平,又,該LED燈板70接近該散熱座60不具滑槽62的二端部分別具有二電連接部71;該管罩80係可透光並呈一半圓柱殼狀,該管罩80係與該散熱座60對接形成一管體且覆蓋該LED燈板70;各燈帽90係套設於該散熱座60及該管罩80對接而成的管體一端並具有二電極端91,其係分別電連 接至該LED燈板70對應該管體一端的二電連接部71以提供該LED燈板70電源。Referring to FIG. 18, the LED lamp tube includes a heat sink 60, an LED lamp board 70, a tube cover 80 and a second lamp cap 90. The heat sink 60 has a semi-cylindrical shape with a circular arc facing outward. A plurality of heat dissipating fins 61 are formed on one side of the heat sink 60. The two opposite sides of the heat dissipating block 60 having a flat surface parallel to the axial direction of the semi-cylindrical body respectively have a sliding slot 62. The LED lamp board 70 is disposed on the heat sink 60 and is in contact with The heat sink 60 has a flat surface and has a plurality of LED elements 72. The LED light board 70 is slidably disposed on the sliding slot 62 of the heat sink 60, and the end of the LED light board 70 is flush with the heat sink 60. The lamp board 70 is adjacent to the heat sink 60 and has two electrical connection portions 71 at the two ends of the heat sink 60. The tube cover 80 is light transmissive and has a semi-cylindrical shell shape. The tube cover 80 is docked with the heat sink 60. Forming a tube body and covering the LED lamp panel 70; each of the lamp caps 90 is sleeved on one end of the tube body formed by the heat sink 60 and the tube cover 80, and has two electrode ends 91, which are respectively electrically connected The LED light board 70 is connected to the two electrical connection portions 71 at one end of the tube body to provide power for the LED light board 70.
使用者將既有LED燈管插設於燈座中並打開開關,該LED燈板70透過該燈帽90的電極端91取得電源後開始以該LED元件72發光,該LED燈板70運作時所產生之熱能則經由該散熱座60導熱至其散熱鰭片61以增加導熱面積進一步提升散熱的效果。The user inserts the existing LED tube into the socket and opens the switch. After the LED board 70 receives the power through the electrode end 91 of the lamp cap 90, the LED element 72 starts to emit light. When the LED board 70 is operated, the LED board 70 is operated. The generated heat energy is thermally conducted to the heat dissipation fins 61 via the heat sink 60 to increase the heat conduction area to further enhance the heat dissipation effect.
請再配合參閱圖19,既有LED燈管的缺陷在於:由於該LED燈板70端部與該散熱座60齊平,又該電連接部71係位於該LED燈板70端部,因此,該電連接部71係與該散熱座60的滑槽62相當接近,又,該電連接部71為導電元件而該散熱座60及滑槽62的材質皆為易導電之金屬,即,該電連接部71與該散熱座60之間的爬電距離d1相當短,因此當該電連接部71該LED燈管運作時,會因為連接高電壓,該電連接部71附近的LED燈板70表面係呈電極化,使得該電連接部71的高電壓透過電極化的LED燈板70表面很容易在爬電距離很短的情況下與該散熱座60短路,損壞該LED燈管,甚至對使用者造成危險。Referring to FIG. 19 again, the defect of the LED lamp tube is that the end portion of the LED lamp board 70 is flush with the heat sink 60, and the electrical connection portion 71 is located at the end of the LED lamp board 70. The electrical connection portion 71 is substantially close to the sliding slot 62 of the heat sink 60. The electrical connection portion 71 is a conductive element, and the heat sink 60 and the chute 62 are made of an electrically conductive metal, that is, the electric The creepage distance d1 between the connecting portion 71 and the heat sink 60 is relatively short. Therefore, when the LED lamp is operated by the electrical connecting portion 71, the surface of the LED light board 70 near the electrical connecting portion 71 may be connected due to the connection of a high voltage. The electrode is electrically polarized, so that the high voltage of the electrical connection portion 71 is easily short-circuited with the heat sink 60 under the condition that the creepage distance is short, and the LED tube is damaged or even used. It is dangerous.
此外,既有LED燈管的燈帽90僅係套設於該管罩80的端部上,結構上並不穩固,且容易於組裝時不小心旋轉該燈帽90,而造成該LED元件72偏轉改變照射角度。In addition, the lamp cap 90 of the LED tube is only sleeved on the end of the tube cover 80, which is not stable in structure, and is easy to rotate the lamp cap 90 during assembly, thereby causing the LED element 72 to be formed. The deflection changes the illumination angle.
