M345944 八、新型說明： 【新型所屬之技術領域】 本創作係關於一種發光二極體燈泡，特別是指一 種螺合於一燈泡座，並且外觀無任何螺合元件之發光 二極體燈泡。 【先前技術】 發光二極體（Light Emitting Diode; LED )係為一 種通電時可發光之電子元件，其發光原理是將電能轉 換為光，也就是將P-N接合注入少數載體，使其與多 數載體再結合而發出自然光之二極體，欲使LED發 光良好必須有極多之電子-電洞對直接復合。當LED 施以順向偏壓後，空間電荷層變窄，基於兩侧之費米 能階差異，所以P-N兩側之主要載體分別注入N側 及P側。由於兩側之少數載體大量增力口，使兩側之間 進行大量電洞-電子對的再複合，並放出足夠之光子 數；目前發光二極體之種類大致包含GaAs，GaN， AlInGaP 等系列。此外，在 GaAs，GaN，AlInGaP 系列 中摻雜氮原子亦會改變其發光之顏色。 同時，相較於傳統的白熾燈泡，LED之耗電量約 僅八分之一’壽命卻高達到五十至一百倍。由於LED 具有質量輕、體積小、耗電量低、使用壽命長等優點， 如今有許國家都開始著手制定相關法規，藉以訂定汰 換傳統白熾燈泡之具體時程表。在此前提下，許多新 式的LED燈泡就逐漸孕育而生。 然而，相較於傳統的白熾燈泡，由於LED通常 6 M345944 必須由驅動積體電路（Driver Integrated Circuit; Driver 1C)所驅動，因此，必須設置方>一電路板上。 • 再者，由於在高溫狀態下，Driver 1C和LED的運作 效率通常會比較差，而且也比較容易損壞；因此，往 ' 往必須再結合適當的散熱模組來逸散熱能，藉以確保M345944 VIII. New description: [New technical field] This creation is about a light-emitting diode bulb, especially a light-emitting diode bulb that is screwed to a bulb holder and has no screwing elements. [Prior Art] A Light Emitting Diode (LED) is an electronic component that emits light when energized. The principle of illumination is to convert electrical energy into light, that is, to inject a PN junction into a minority carrier to make it compatible with a majority carrier. Combined with the natural light diode, in order to make the LED shine well, there must be a lot of electron-hole pairs directly compounded. When the LED is applied with a forward bias, the space charge layer is narrowed, and based on the Fermi level difference on both sides, the main carriers on both sides of the P-N are injected into the N side and the P side, respectively. Due to the large number of carriers on both sides, a large number of holes-electron pairs are recombined on both sides, and enough photons are released. Currently, the types of light-emitting diodes mainly include GaAs, GaN, AlInGaP, etc. . In addition, the doping of nitrogen atoms in the GaAs, GaN, and AlInGaP series also changes the color of the light. At the same time, compared to traditional incandescent bulbs, LEDs consume only about one-eighth of their power consumption, but their lifetimes are as high as 50 to 100 times. Due to the advantages of light weight, small size, low power consumption and long service life, many countries have begun to develop regulations to determine the specific time schedule for replacing traditional incandescent bulbs. Under this premise, many new LED bulbs have been born. However, compared to the conventional incandescent bulb, since the LED usually 6 M345944 must be driven by the driver integrated circuit (Driver Integrated Circuit; Driver 1C), it must be set on a board. • Furthermore, because of the high temperature, the operating efficiency of Driver 1C and LED is usually poor, and it is also relatively easy to damage; therefore, it is necessary to combine the appropriate thermal module to dissipate heat, so as to ensure
Driver 1C和LED不至於在過高的溫度下運作。因此， 現有的LED燈泡通常都會具有電路板和散熱模組。 . 此外，為了確保電路板不至於短路，通常在電路 板和燈泡座之間還會具備有一塑膠製之絕緣基座，絕 φ 緣基座係包覆一金屬製之導電底殼，藉以螺合於燈泡 座以導入電力。同時，為了防止灰塵進入LED和電 路板所在之位置，通常還會以一塑膠、壓克力或玻璃 製之光學封裝片來加以封裝。 在上述背景下，在現有的LED燈泡中，通常係 利用螺絲來結合散熱模組、絕緣基座與透光封裝片等 外部元件。然而，在實務運用層面上，這種組裝結合 方式卻普遍存在三個缺點： 其一，在受到外力衝擊或溫度急遽變化時，會使 • 散熱模組、絕緣基座與光學封裝片承受較大的應力或 ' 熱應力。此時，在結合金屬製螺絲處，特別是在金屬 - 製螺絲、塑膠製絕緣基座與光學封裝片間，會形成較 為明顯的應力或熱應力不連續區域，因而造成應力集 中現象，並導致在結合螺絲處的絕緣基座或透光封裝 片容易老化或龜裂。 其二，由於必須結合多個螺絲，在製作LED燈 泡時，製作程序會比較煩瑣，並因而造成耗費組裝工 時與成本之問題。 其三，由於必須結合螺絲，在結合螺絲之鬆緊度 7 M345944 不一致時，會產生翹曲或歪斜現象，在外觀上會變得 比較不美觀，且質感會變得比較差。 【新型内容】 本創作所欲解決之技術問題與目的： 有鑒於習知技術所提供之LED燈泡，必須利用 螺絲來組裝外部元件，因此，容易因為應力或熱應力 集中而造成絕緣基座或透光封裝片容易老化或龜 裂，耗費較多的組裝工時與成本，以及不美觀與質感 較差等問題。 緣此，本創作之主要目的在於提供一種LED燈 泡，其係利用自體螺合或嵌合的方式來結合散熱模 組、基座、導電底殼與透光封裝片等外部元件，藉以 減缓應力集中現象，精簡製作程序，並避免因結合螺 絲之鬆緊度不一致而產生之翹曲或歪斜現象。 本創作解決問題之技術手段： 本創作為解決習知技術之問題所採用之技術手 段係提供一種發光二極體（LED)燈泡，其係用以螺 合於一燈泡座，並且包含一基座、一導電底殼、一散 熱模組、一燈杯、一電路板與一光學封裝片。基座係 分別自體螺合於導電底殼與散熱模組，導電底殼係供 螺合於燈泡座；散熱模組包含一散熱本體與複數個自 散熱本體向外輻射延伸之散熱鰭片；電路板設置複數 個LED，燈杯藉由電路板而結合於散熱模組，並且開 設複數個開孔；光學封裝片嵌合於燈杯，並且具備數 個光學透鏡。上述之複數個LED、開孔與光學透鏡係 M345944 彼此對應。 本創作對照先前技術之功效： 相較於習知之LED燈泡，由於本創作所提供之 LED燈泡係利用自體螺合的方式來結合基座、導電底 殼與散熱模組，並且利用嵌合的方式來結合光學封裝 片丄因此；所有外部元件之結合都不需要使用螺絲二 螺管、螺栓或螺桿等螺合媒介，可藉以避免因為應力 集中而造成之基座與光學封裝片老化或龜裂等問題。 此外，由於係利用自體螺合或嵌合的方式來έ士人 基座、導電底殼與散熱模組；因此，可以有 : 裝程序，藉以節省組裝工時與成本;也因:二 免因結合螺絲之鬆緊度不一致而產生之翹曲或歪斜 現象，使LED燈泡具備較美觀之外觀與較佳之質感。 本創作所採用的具體實施例，將藉由以下之 例及圖式作進一步之說明。 、 _ 【實施方式】 . 由於本創作所提供之發光二極體燈泡可廣泛運 用於結合各種習知之燈泡座，以其組合實施方式更是 不勝枚舉，故在此不再 贅述，僅列舉其中一個齡 佳之實施例加以具體說明。 T彳口1 乂 土請參閱第一圖至第五圖，第一圖係顯示本創作較 ^實施例之主要元件分解圖；第二圖係顯示本創作較 佳實施例之立體外觀圖；第三圖係顯示本創作較佳實 ，例^散熱模組之立體外觀圖；第四圖係顯示本創作 較佳實施例之燈杯之立體外觀圖；第五圖係顯示本創 9 M345944 作較佳實施例之光學封裝片之立體外觀圖。如圖所 示，一發光二極體（Light Emitting Diode; LED)燈泡 . 100，係用以螺合於一燈泡座200，藉以取代傳統之白 熾燈泡。 LED燈泡100包含一基座1、一導電底殼2、一 散熱模組3、一電路板4、一燈杯5、一光學封裝片6 與一固定環7。 - 基座1通常係由塑膠射出成型所製成，呈一近似 管狀結構，並且包含一基座本體11、一第一螺紋段 ❿ 12與一第二螺紋段13。第一螺紋段12係位於基座本 體11鄰近於散熱模組3之一端，第二螺紋段13係位 於基座本體Π遠離散熱模組3之另一端，且第二螺 紋段13之外徑係小於第一螺紋段12之外徑。Driver 1C and LEDs do not operate at excessive temperatures. Therefore, existing LED bulbs usually have a circuit board and a heat dissipation module. In addition, in order to ensure that the circuit board is not short-circuited, there is usually a plastic insulating base between the circuit board and the bulb base, and the φ-edge base is covered with a metal conductive bottom case for screwing. At the bulb holder to introduce power. At the same time, in order to prevent dust from entering the LED and the board where it is located, it is usually packaged in a plastic, acrylic or glass optical package. Under the above background, in the conventional LED light bulb, external components such as a heat dissipation module, an insulating base, and a light-transmitting package sheet are usually combined by screws. However, at the practical application level, there are three common shortcomings in this combination of assembly methods: First, when subjected to external force impact or sudden temperature changes, the heat dissipation module, the insulating base and the optical package sheet are subjected to a large Stress or 'thermal stress. At this time, in combination with the metal screw, especially between the metal-made screw, the plastic insulating base and the optical encapsulating sheet, a relatively obvious stress or discontinuous region of thermal stress is formed, thereby causing stress concentration and causing The insulating base or the light-transmitting encapsulating sheet at the bonding screw is easily deteriorated or cracked. Second, since it is necessary to combine a plurality of screws, the production process is cumbersome when manufacturing the LED bulb, and thus the assembly time and cost are caused. Thirdly, since it is necessary to combine the screws, when the tightness of the combined screws 7 M345944 is inconsistent, warping or skewing may occur, and the appearance may become unattractive and the texture may become poor. [New content] The technical problems and objectives to be solved by this creative: In view of the LED bulbs provided by the prior art, screws must be used to assemble external components, so that it is easy to cause insulation base or penetration due to stress or thermal stress concentration. The optical encapsulating sheet is prone to aging or cracking, and requires a lot of assembly man-hours and costs, as well as problems such as unsightly and poor texture. Therefore, the main purpose of the present invention is to provide an LED light bulb which utilizes an automatic screwing or fitting method to combine external components such as a heat dissipation module, a base, a conductive bottom case and a light-transmitting package piece, thereby slowing down. Stress concentration, streamline the production process, and avoid warping or skewing due to inconsistent tightness of the combined screws. The technical means for solving the problem in this creation: The technical means adopted by the present invention to solve the problem of the prior art is to provide a light-emitting diode (LED) bulb which is screwed to a bulb holder and includes a base. , a conductive bottom case, a heat dissipation module, a light cup, a circuit board and an optical package sheet. The pedestal is respectively screwed to the conductive bottom case and the heat dissipation module, and the conductive bottom case is screwed to the lamp holder; the heat dissipation module comprises a heat dissipation body and a plurality of heat dissipation fins radiating outward from the heat dissipation body; The circuit board is provided with a plurality of LEDs, the lamp cup is coupled to the heat dissipation module by a circuit board, and a plurality of openings are opened; the optical package sheet is fitted to the lamp cup and has a plurality of optical lenses. The plurality of LEDs and apertures described above correspond to the optical lens system M345944. Compared with the conventional LED bulbs, the LED bulbs provided by the present invention are combined with the pedestal, the conductive bottom case and the heat dissipation module by using the self-threading method, and the fitting is utilized. The way to combine the optical encapsulation sheet; therefore, the combination of all external components does not require the use of screwing media such as screws, bolts or screws to avoid aging or cracking of the susceptor and the optical encapsulation sheet due to stress concentration. And other issues. In addition, since the self-body screwing or fitting is used for the gentleman base, the conductive bottom case and the heat dissipation module; therefore, there may be: loading procedures to save assembly time and cost; The warp or skew caused by the inconsistent elasticity of the combined screws makes the LED bulb have a more aesthetic appearance and a better texture. The specific embodiments used in the present application will be further illustrated by the following examples and drawings. _ [Embodiment] Since the light-emitting diode bulb provided by the present invention can be widely used in combination with various conventional light bulb holders, the combination implementation manner is even more numerous, so it will not be repeated here, only enumerated therein.
