Description
本發明係有關於一種沖壓式散熱件及其製作方法，尤指一種適用於發光二極體燈泡及燈具中之散熱結構，藉以加速散熱過程。The invention relates to a stamping heat sink and a manufacturing method thereof, in particular to a heat dissipating structure suitable for a light emitting diode bulb and a lamp, thereby accelerating the heat dissipation process.
現代的鎢絲白熾燈約於十九、二十世紀交接時期研製成功，裡面的發光體採用了鎢絲製成的燈絲，這種材料特點是其熔點很高，在高溫下仍能保持固態，如此才能使得燈泡有一定的壽命，燈絲不會在短時間就燒斷而無法使用。實際上，一隻點亮的白熾燈的燈絲溫度高達3000℃，而正是由於熾熱的燈絲產生了光輻射，才使電燈發出了明亮的光芒。而自此，夜晚的降臨對於人們的生活不再是種阻礙，有了白熾燈泡的大放光明，在夜間的種種活動，無論是工作或生活上，都能很便利的繼續下去，開展了更多可能性，白熾燈泡的發明可說大大的改變人們的生活型態，將活動的時段往更多面向延伸出去，進而有更不一樣的種種發展。
而隨著照明科技的進展，各式照明燈具一一被開發出來，而在所有用電的照明燈具中，白熾燈泡的效率是最低的，所消耗的電能轉成光能的部份只有12%－18%，能源轉換相當的差，其餘部分都以熱能的形式散失，而浪費掉了大部分的能量。是故，隨著科技的日益進展，發光二極體(Light Emitting Diode，LED)之技術，與相關週邊積體電路控制元件及散熱技術的日漸成熟，使其應用更加多元化，諸如低功率的電源指示燈及手機鍵盤光源，到LED背光模組與一般照明產品，是以逐漸取代傳統常用之發光源，較於白熾燈泡之壽命短及發燙，發光二極體有著耗電低、不含汞、不含鹵化物及二氧化碳排放量低等優勢，為了日漸為人重視之環保議題，節能減碳，減少汞及鹵化物使用的多方考量下，各國政府已明令限期禁用白熾燈並全面推廣發光二極體。
且由於發光二極體的發光特性，是光源點的模式，故設計上更有彈性，可以做出分散光源而不刺眼的燈具，也能做集中一點或特定區域的燈具，所產生的顏色能夠更鮮艷明亮，白光 LED發光效率目前已達70 lm/W，已超過白熾燈泡的15 lm/W。但是，目前發光二極體的輸入功率僅有35％會轉換成光，其餘65%則轉變成為熱，產生之該些熱量，是造成發光二極體其發光效率降低的元兇，再者，發光二極體所產生之熱能，若其整個裝置之散熱機制不佳，導致了熱能累積於發光二極體無法即時導出，則會使得發光二極體之壽命縮短，一般來說，LED燈的壽命在100000小時以上，但如果工作溫度高於85℃，就會大大減低壽命。
所以包含LED燈泡在內，燈泡在使用時，熱量上升是必然的結果，散熱是解決此問題的手段，而相關技術的著眼點，會放在如何提昇各部之散熱效率，使熱量加速散去而使用壽命獲得提昇。LED燈中，發熱源有二，分別為發光源與電源驅動器，兩者之散熱都需要加以處理，倘若散熱機制不佳，發光源產生的熱能以熱傳導方式傳到正中央時，會與電源驅動器產生的熱能發生共熱效應，在此效應之下造成了內部溫度過高，使得電源驅動器內的電子零件受損，除了嚴重影響電源驅動器的壽命，且發光源的溫度也因共熱效應而降不下來，使得發光效率降低，這往往是因為電源驅動器內部發生損壞所致，而非發光源本身發光效能有問題，且，溫度因為共熱效應而向上飆昇，除了會降低燈泡使用壽命之外，也會有提高室內溫度，造成使用者不適的困擾，是故散熱機制在此是相當重要的一個課題。
有鑑於各式燈泡使用時，若燈座沒有規劃散熱機制時，使得發光源與電源驅動器的熱量會難以散去，因此產生不良的影響，本發明提供一種沖壓式散熱件及其製作方法，該沖壓式散熱件主要應用於燈泡之散熱。其製作方法係為沖壓一金屬片而製成，並為一體成型，再經摺製得到所需之散熱件，置於LED燈杯中，能夠有效的將燈內之發熱源，例如光源基板及電源連接部，所產生的熱快速導引到燈杯，再透過燈杯及燈杯上的散熱孔散熱出去，如此之結構除了能提昇燈泡的使用壽命之外，對於生產者來說也更為簡便，只需調整沖壓模具，直接就能夠沖出指定尺寸的散熱件，以直接搭配各式的燈杯。Modern tungsten incandescent lamps were successfully developed during the handover period of the 19th and 20th centuries. The illuminators used were filaments made of tungsten wire. This material is characterized by its high melting point and its ability to remain solid at high temperatures. In this way, the bulb can have a certain life span, and the filament will not be blown out in a short time and cannot be used. In fact, the temperature of a filament of a lit incandescent lamp is as high as 3000 ° C, and it is because of the light radiation generated by the hot filament that the lamp emits a bright light. Since then, the coming of the night is no longer a hindrance to people's lives. With the bright light of incandescent light bulbs, all kinds of activities at night, whether at work or in life, can be easily carried on and carried out more. Many possibilities, the invention of incandescent bulbs can be said to greatly change people's life style, and extend the period of activities to more aspects, and thus have more different developments.
With the development of lighting technology, various lighting fixtures have been developed one by one. Among all the lighting fixtures, the efficiency of incandescent bulbs is the lowest, and only 12% of the energy consumed is converted into light energy. -18%, the energy conversion is quite poor, and the rest is lost in the form of heat, and most of the energy is wasted. Therefore, with the advancement of technology, the technology of Light Emitting Diode (LED), and related peripheral integrated circuit control components and heat dissipation technology are becoming more and more mature, making its application more diversified, such as low power. The power indicator light and the mobile phone keyboard light source, to the LED backlight module and general lighting products, are gradually replacing the traditional commonly used light source. Compared with the incandescent light bulb, the life is short and hot, and the light-emitting diode has low power consumption and does not contain Mercury, halogen-free and low carbon dioxide emissions, in order to pay more attention to environmental issues, energy conservation and carbon reduction, reducing the use of mercury and halides, governments have banned incandescent lamps for a limited time and fully promoted the luminescence Diode.
And because of the illuminating characteristics of the light-emitting diode, it is the mode of the light source point, so the design is more flexible, and the illuminating device can be made without distracting the light source, and can also be used for concentrating a little or a specific area of the luminaire, and the color produced can More vivid and bright, the luminous efficiency of white LEDs has reached 70 lm/W, which has exceeded 15 lm/W of incandescent bulbs. However, at present, only 35% of the input power of the light-emitting diode is converted into light, and the remaining 65% is converted into heat. The heat generated is the culprit of the luminous efficiency of the light-emitting diode, and further, the light is emitted. The thermal energy generated by the diode, if the heat dissipation mechanism of the whole device is not good, causes the thermal energy to accumulate in the light-emitting diode, and the life of the light-emitting diode is shortened. Generally, the life of the LED lamp is shortened. More than 100,000 hours, but if the operating temperature is higher than 85 ° C, it will greatly reduce the life.
Therefore, when the bulb is used, the heat rise is an inevitable result. The heat dissipation is a means to solve this problem, and the related technology focuses on how to improve the heat dissipation efficiency of each part and accelerate the heat dissipation. The service life has been improved. In the LED lamp, there are two heat sources, which are the light source and the power driver. The heat dissipation of both needs to be processed. If the heat dissipation mechanism is not good, the heat generated by the light source is transmitted to the center by heat conduction, and the power driver The generated thermal energy has a co-heating effect, and the internal temperature is too high under this effect, so that the electronic components in the power driver are damaged, except that the life of the power driver is seriously affected, and the temperature of the light source cannot be lowered due to the common heat effect. , so that the luminous efficiency is reduced, which is often caused by damage inside the power driver, but the luminous efficiency of the non-luminous source itself is problematic, and the temperature rises up due to the common heat effect, in addition to reducing the life of the bulb, there will be Increasing the indoor temperature causes user discomfort, so the heat dissipation mechanism is a very important issue here.
In view of the use of various types of light bulbs, if the lamp holder does not have a heat dissipation mechanism, the heat of the light source and the power source driver may be hard to be dissipated, thereby causing adverse effects. The present invention provides a stamping heat sink and a manufacturing method thereof. The stamped heat sink is mainly used for heat dissipation of the bulb. The manufacturing method is made by stamping a metal piece, and is integrally formed, and then obtained by folding to obtain a required heat sink, which is placed in the LED lamp cup, and can effectively heat the heat source in the lamp, such as the light source substrate and At the power connection, the generated heat is quickly guided to the lamp cup and then dissipated through the heat dissipation holes in the lamp cup and the lamp cup. In addition to improving the service life of the lamp, the structure is also more suitable for the producer. It's simple, just adjust the stamping die and directly punch out the heat sink of the specified size to directly match all kinds of lamp cups.
