按，LED燈泡係具有耗電量低及使用壽命長的特性，而於環保節能的前提下，無論是公共照明或家庭照明，已有逐漸一般白熾燈泡或省電燈泡之趨勢。According to the LED light bulb, it has the characteristics of low power consumption and long service life. Under the premise of environmental protection and energy saving, whether it is public lighting or home lighting, there is a tendency to gradually become an incandescent bulb or a power saving bulb.

請參閱第1圖所示，係為坊間習用之LED燈泡10，其主要係於燈泡本體11之一端設有承座111，以供裝設具複數個LED元件121之電路基板12，另端設有與電路基板12作電性連接之電源接頭13，以供連接電源，並驅動電路基板12之複數個LED元件121發出光線照明，由於LED元件121受到其發光特性之限制，其光線僅能向前方投射，而以造成炫光及照明不均之情況，為使LED元件121所發出之光線能均勻向外擴散投射，一般會於電路基板12之複數個LED元件121上罩合一概呈辦圓球型之燈罩14，而利用該燈罩14使LED元件121所發出之光線均勻向外擴散投射；惟，該LED燈泡10之LED元件121發出之光線透過燈罩14時，其光線所產生之折射擴散角度有限，使得大部分光線經由燈罩14向外擴散投射後，仍集中向前 方處投射，其雖有部份之光線經由燈罩14反射，然而，該部份反射光線卻受到燈泡本體11之承座111阻擋，而限制反射光線之擴散角度，使燈罩14之前方位置較為明亮，而周側位置則較為昏暗，因此，該LED燈泡10之光線仍無法充分的擴散投射，而影響其照明效果。Referring to FIG. 1 , the LED bulb 10 is a conventionally used LED bulb 10 , which is mainly provided with a socket 111 at one end of the bulb body 11 for mounting a circuit board 12 having a plurality of LED elements 121, and the other end is provided. There is a power connector 13 electrically connected to the circuit board 12 for connecting a power source, and driving a plurality of LED elements 121 of the circuit board 12 to emit light. Since the LED element 121 is limited by its light-emitting characteristics, the light can only be directed to In the case of projecting in front, in order to cause glare and uneven illumination, in order to uniformly spread the light emitted by the LED element 121, a plurality of LED elements 121 on the circuit substrate 12 are generally covered. The bulb of the ball type 14 is used, and the light emitted by the LED element 121 is uniformly diffused and projected by the lamp cover 14; however, when the light emitted from the LED element 121 of the LED bulb 10 passes through the lamp cover 14, the light is diffused and diffused. The angle is limited, so that most of the light is diffused and projected through the lampshade 14 and still concentrates forward. The square is projected, although some of the light is reflected by the lamp cover 14, however, the partially reflected light is blocked by the socket 111 of the bulb body 11, and the diffusion angle of the reflected light is restricted, so that the position of the lamp cover 14 is brighter in the front. The position on the side of the circumference is relatively dim. Therefore, the light of the LED bulb 10 is still unable to be sufficiently diffused and projected, thereby affecting the lighting effect.
