M317539 八、新型說明： 【新型所眉之技術領域】 本創作係為一種發光二極體燈具，尤指一種利用 LED(Light Emitting Diodes)發光二極體之外緣設有複數個散 熱銪片，可將其所產生之熱量迅速排出之發光二極體燈具。 【先前技術】 市面上各式各樣的燈具中，投射燈長久以來一直佔了相 當固定之比例。尤其是在各種電子省電燈泡取代傳統日光燈 管的同時’投射燈因為其所能提供的特殊照明效果，而仍能 在燈具市場上佔有一席之地。不論在居家裝潢的設計，以及 各式展場的設計或是餐廳的裝潢，不可避免的都會利用投射 燈來營造氣氛’突顯所要展示的商品或裝飾。由於投射燈的 市場相當大，因此市場早已經將其大小規格化，傳統的投射 燈’係使用110伏特之卣素投射燈泡，不但粍電量高，且容 易發熱，相對的壽命也非常短，平均壽命只有幾個月，在這 個電價高療的年代，不僅非常不環保，且其所教發之高熱亦 容易造成電線走火等危險意外。 是以’有鑑於此，曾有業者推出一種以LED為照明光源 之我射燈’利用LED之低耗電量等特性來改善傳統由素投射 燈’色之缺失。請參閱圓一所示，圖一為習用之LED投射燈泡 之外觀示意囷。其中，該習用之LED投射燈泡1係主要由外 卜電屋轉換單元12、以及LED單元13所紐成。該led 單兀13及電愿轉換單元！2係設於該金屬製成之外殼11内。 5 M317539 藉由該電壓轉換單元12將原本lio伏特之交流電轉換成可提 供LED單元13使用之直流電，使LED單元13可以發光而 達到投射效果。 惟前述習用之LED投射燈泡1結構，雖然相較於傳統之 鹵素投射燈泡具有省電環保之功效，但是同樣的，使用led 單元13也會有散熱的問題存在。因為要達到單點投射的效 果，該LED單元13本身就要達到一定程度之亮度，雖然現 在科技的進步快速，該LED單元13的亮度也在不斷的提昇 當中，但是同樣的也會遇到相同的散熱問題。尤其LED單元 13相較於傳統由素投射燈泡，其耐熱程度更低，且一但溫度 超遇其容許設定值時，該LED單元13所產生的亮度就會發 生滾減的現象而無法達到預期的效果，甚至縮減其正常之使 用壽命。 雖然如此，習用之LED投射燈泡1結構並未在散熱結構 上有任何加強之處，因此，對於LED單元13做動時所產生 的截能，只能依靠金屬製成的外殼11慢慢散到空中，散熱效 果可以說是相當的不理想。因此目前該類之習用之LED投射 燈跑1，最多僅能使用1瓦的LED單元13，導致其所能提供 的查度受到一定之限度，而無法有效提昇並取代傳統之鹵素 投射燈泡。使得高耗電、高發熱的傳統鹵素投射燈泡一直仍 佔有一定比例的市場，造成相當多的能源浪費。 【新型内容】

New Description: [Technical field of new type eyebrow] This creation is a kind of light-emitting diode lamp, especially a kind of heat-dissipating film with the outer edge of LED (Light Emitting Diodes) light-emitting diode. A light-emitting diode lamp that can quickly dissipate the heat generated by it. [Prior Art] Among all kinds of lamps on the market, the projection lamps have been occupying a relatively fixed ratio for a long time. Especially when various electronic power-saving bulbs replace traditional fluorescent tubes, the 'projection lamps' still have a place in the lighting market because of the special lighting effects they can provide. Regardless of the design of the home decor, the design of the various exhibition halls or the decoration of the restaurant, it is inevitable that the projector will be used to create an atmosphere that highlights the goods or decorations to be displayed. Since the market for projection lamps is quite large, the market has already standardized its size. The traditional projection lamps use 110 volts of halogen projection bulbs, which not only have high electric power, but also are prone to heat, and the relative life is very short. The life span is only a few months. In this era of high price of electricity, it is not only very environmentally unfriendly, but the high heat it teaches can easily lead to dangerous accidents such as wire fire. Therefore, in view of this, some manufacturers have introduced a kind of light that uses LED as an illumination source to improve the lack of color of the conventional projection lamp by utilizing the low power consumption of the LED. Please refer to the circle one. Figure 1 shows the appearance of the conventional LED projection bulb. Among them, the conventional LED projection lamp 1 is mainly made up of the external electric house conversion unit 12 and the LED unit 13. The led single 13 and the power conversion unit! 2 is provided in the outer casing 11 made of the metal. 5 M317539 The original voltage of the liovolt is converted into a direct current which can be used by the LED unit 13 by the voltage converting unit 12, so that the LED unit 13 can emit light to achieve a projection effect. However, the conventional LED projection lamp 1 structure has a power saving effect compared to the conventional halogen projection lamp, but similarly, the use of the led unit 13 has a problem of heat dissipation. Because of the effect of single-point projection, the LED unit 13 itself must reach a certain degree of brightness. Although the advancement of technology is rapid, the brightness of the LED unit 13 is constantly improving, but the same will be encountered. The problem of heat dissipation. In particular, the LED unit 13 has a lower heat resistance than the conventional projection bulb, and once the temperature exceeds its allowable set value, the brightness generated by the LED unit 13 is reduced and cannot be expected. The effect even reduces its normal life. However, the conventional LED projection lamp 1 structure does not have any reinforcement on the heat dissipation structure. Therefore, the interception energy generated when the LED unit 13 is actuated can only be slowly dispersed by the outer casing 11 made of metal. In the air, the heat dissipation effect can be said to be quite unsatisfactory. Therefore, the conventional LED projection lamps of this type can only use one watt of LED unit 13 at a time, so that the degree of the inspection can be provided to a certain extent, and the conventional halogen projection bulb cannot be effectively upgraded and replaced. The traditional halogen projection bulbs that make high power consumption and high heat generation still occupy a certain proportion of the market, causing considerable energy waste. [New content] The main purpose of this creation is to provide a light-emitting diode lamp.
