Description
本發明是有關於一種LED燈泡結構及增加光源廣度之方法，尤指一種可提高光源照射廣度並增加照射範圍之LED燈泡結構及增加光源廣度之方法。
The invention relates to a structure of an LED bulb and a method for increasing the breadth of the light source, in particular to a method for improving the illumination range of the light source and increasing the illumination range of the LED bulb and increasing the breadth of the light source.
隨著科技產業不斷的進步，使傳統的燈泡已逐漸被取代，取而代之的是一般人所熟知的發光二極體(LED)，由於LED憑藉著體積小、所需電能小、發光率高、使用時間長、無汞污染性等優點，使得光電產業及照明產業皆採用LED光源作為使用，目前已普遍出現於一般日常生活中。
如第1圖所示，係為習知以LED為光源之泡燈，該泡燈係包括：一燈罩10、一電源座11及一LED模組12，該電源座11具有一開口111，所述LED模組12係固設於該電源座11之開口111處，且該LED模組12具有至少一LED晶片121及一電路基板122，所述燈罩10係罩蓋於該LED模組12上。
由於使用LED模組12之泡燈其光線特性為具有方向性，其LED模組12光源照射角度約為120度，故其向前方直射的正向光最強，而側邊及後方之光源則相對較微弱甚至無光源，因此光源無法照射至泡燈兩側及後方，如此一來，所照射出來的光源周圍偏暗，致使照明廣度較窄小，且照射範圍較小。

The lamp cover 10 is covered on the LED module 12 . .
Since the light bulb of the LED module 12 has a directional characteristic, the illumination angle of the LED module 12 is about 120 degrees, so that the forward light directly toward the front is the strongest, and the light sources on the side and the rear are relatively It is weak or even no light source, so the light source cannot be irradiated to both sides and the rear of the bulb.
