Description

M270407 四、創作說明(1) 【新型所屬之技術領域】 本創作係有關一種光源結構,特別是有關一種具散熱 裝置之平面發光源結構。 【先前技術】 按’隨著科技的進步,從一般鎢絲燈發展至現今的冷 陰極螢光燈 f (Cold Cathode Fluorescent Lamp, CCFL) 及發光二極體(Light Emitting Diode,LED),皆係朝向 體積縮小及扁平化的方向發展。 而目前CCFL因為體積幾乎是不能再縮小,而且CCFL在 升壓到6 0 0伏特電壓時會發生干擾,另外CCFL會造成汞污 染的問題,使得部份國家也將予以禁用。所以LED己漸漸 取代CCFL。然而現今的高亮度LED所產生的局部熱量巨 大,若要取代CCFL作為照明產品,則必須要有合適的散熱 設計,否則會造成LED發光效率降低及壽命縮短等問題, 所以現今LED封裝結構多利用金屬承載基板(Metal Core Print Circuit Board,MCPCB)作為散熱媒介,但 LED仍 無法以高密集度方式設置,原因在於散熱能力仍無法有效 突破,因此有關LED散熱問題部分,是目前業界亟需克服 的難題。 有鑑於.此,本創作係釙對上述之問題,提出一種具高 散熱效率之平面發光源結構,以有效解決上述問題。M270407 IV.

At present, the CCFL can hardly be reduced because of its volume, and the CCFL will interfere when it is boosted to 600 volts. In addition, the CCFL will cause the problem of mercury pollution, and some countries will also ban it. So LED has gradually replaced CCFL. However, today ’s high-brightness LEDs generate huge amounts of local heat. To replace CCFLs as lighting products, they must have a proper heat dissipation design, otherwise they will cause problems such as reduced LED luminous efficiency and shortened life. Therefore, today ’s LED packaging structures make more use of A metal carrier substrate (MCPCB) is used as a heat dissipation medium, but LEDs cannot be set in a high-density manner because the heat dissipation ability cannot be effectively broken. Therefore, the LED heat dissipation problems are currently urgently needed to be overcome in the industry. problem. In view of this, the author proposes a planar light source structure with high heat dissipation efficiency to solve the above problems in order to effectively solve the above problems.
