In particular, the present invention relates to a ceramic substrate as a carrier, a plurality of heat conducting columns are formed on the ceramic substrate, and a plurality of independent light beams are arranged on the plane. Light source device for the diode module.
發光二極體低用電、高亮度的特性,使其符合現代講究能源節約的使用需求,近幾年有關發光二極體的技術發展已臻於相當成熟的情況,是以,從早期低亮度,僅能作為替代性光源之使用需求演變至今,發光二極體已能符合高亮度、使用壽命長的需求,惟,伴隨而來的問題,則是發光二極體在達到高功率電性使用需求的同時,其所產生的熱能亦隨之大幅升高;依此,若在整體應用上,無法即時將發光二極體所產生的熱能盡速排除,則高溫的情況即會造成發光二極體之使用壽命減短,例如造成晶片快速失效,進而形成光衰減情況提前發生、又例如造成覆蓋於晶片上方的混光層膠體(EXPOXY環氧樹脂)加速黃化、質變等情況,是以,如何將發光二極體所產生的熱能快速發散,乃為目前實體應用上極待解決的問題。The low-power and high-brightness characteristics of the light-emitting diode make it meet the modern energy-saving use requirements. In recent years, the development of the technology of the light-emitting diode has been quite mature, so that it is low-intensity from the early stage. The demand for use as an alternative light source has evolved to date, and the light-emitting diode has been able to meet the requirements of high brightness and long service life. However, the accompanying problem is that the light-emitting diode is in high-power electrical use. At the same time of demand, the heat energy generated by it is also greatly increased; accordingly, if the heat energy generated by the light-emitting diode cannot be eliminated as soon as possible in the overall application, the high-temperature condition will cause the light-emitting diode The service life of the body is shortened, for example, causing rapid failure of the wafer, thereby forming a light attenuation condition to occur in advance, and for example, causing accelerated mixing of the colloidal layer colloid (EXPOXY epoxy resin) over the wafer to accelerate yellowing, qualitative change, etc. How to quickly dissipate the heat generated by the light-emitting diode is an extremely problem to be solved in the current physical application.
請參閱「第1圖」,圖中所示係為一種習知的燈泡型燈具之立體外觀圖,如圖所示的燈泡型燈具1,其主要是應用一發光二極體裝置11作為發光源,現行實體產品中,所應用的發光二極體裝置11其主要係將一印刷有電路線的電路基板112,作為一發光二極體 模組113的載體,製作時,係利用表面粘著技術,使數個發光二極體模組113直接粘著於電路基板112之平面,且各發光二極體模組113係分別與電路線完成電性連接,又,各發光二極體模組113的表面被覆有一混光層膠體(EXPOXY環氧樹脂)114,用以保護各發光二極體模組113的晶片(或同時具有混色的功效);承上,再將發光二極體裝置11組設於一燈座12的組設部121,再將一半球型的燈殼組設後,即製成燈泡型燈具1;此種類型所製成的燈具,主要係使發光二極體裝置11的電路基板112可平貼於燈座12的組設部121,而所述的燈座12通常是以金屬製成,例如鋁或鋁合金,其主要是利用燈座12之材料本身具有較佳的散熱效果,藉以使電路基板112所聚集的熱可經由燈座12進行發散;惟,所述的散熱過程在進行時,電路基板112本身同時也處在高溫的情況中,是以,如在電路基板112上方佈設過多的發光二極體模組113,則常有因溫度過高而導致電路基板112變形的情況,如果電路基板112本身進一步以金屬製成,則其電性連接的部份,又常有短路的情況發生,是以,產品的良率常因此而大受影響。Please refer to "Fig. 1", which is a perspective view of a conventional bulb-type lamp, as shown in the bulb type lamp 1, which mainly uses a light-emitting diode device 11 as a light source. In the current physical product, the applied light-emitting diode device 11 mainly uses a circuit substrate 112 printed with a circuit line as a light-emitting diode.

After the electrical connection is completed, the surface of each of the LED modules 113 is coated with a light-mixing layer colloid (EXPOXY epoxy resin) 114 for protecting the wafers of the LED modules 113 (or at the same time having a color mixture). (Effect)); then, the light-emitting diode device 11 is set in the assembly portion 121 of a lamp holder 12, and then the half-ball type lamp housing is assembled, thereby forming a bulb-type lamp 1; The lamp is mainly made such that the circuit substrate 112 of the LED device 11 can be flatly attached to the assembly portion 121 of the lamp holder 12, and the lamp holder 12 is usually made of metal, such as aluminum or aluminum. The alloy mainly uses the material of the lamp holder 12 to have a better heat dissipation effect, so that the heat accumulated by the circuit substrate 112 can be diverged through the lamp holder 12; however, when the heat dissipation process is in progress, the circuit substrate 112 is in progress. It is also in the case of high temperature at the same time, such as on the circuit substrate 112. If too many LED modules 113 are disposed, the circuit substrate 112 may be deformed due to excessive temperature. If the circuit substrate 112 itself is further made of metal, the electrically connected portions are often A short circuit occurs because the yield of the product is often greatly affected.
