Description
本創作有關於一種燈殼整合型發光二極體(shell integrated LED),特別係有關於一種可360度、四面八方全面發光與光輻射散熱之燈殼整合型發光二極體,其藉由一體固化之方式整合封裝白光發光二極體單元,使得發光燈殼與發光二極體二者合而為一,亦即,發光燈殼扮演白光發光二極體的角色,而白光發光二極體扮演發光燈殼的角色。 The present invention relates to a lamp-integrated light-emitting diode (LED integrated LED), in particular to a lamp-shell integrated light-emitting diode capable of 360-degree, all-round comprehensive illumination and light radiation dissipation, which is integrally cured. The method further comprises encapsulating the white light emitting diode unit, so that the light emitting shell and the light emitting diode are combined into one, that is, the light emitting shell plays the role of a white light emitting diode, and the white light emitting diode plays the light. The role of the lamp shell.
發光二極體(LED)因發光效率與壽命高於傳統之鹵素燈或熾光燈,已為照明發展之重點方向。傳統之發光二極體晶片利用直接封裝(COB;Chip on board)技術,將發光二極體晶片固定在鋁、PCB、或陶瓷基板上,故具有單面發光與發光效率低的困擾。另一種發光二極體晶片之傳統封裝技術係將晶片封裝於玻璃基板上(Chip on glass),雖發光二極體晶片發光效率提高,但玻璃基板之散熱效率不佳、生產良率低、且玻璃基板兩側之出光色溫不同,故此種發光二極體晶片技術仍有待改善。 Light-emitting diodes (LEDs) have become the focus of lighting development due to their higher luminous efficiency and lifetime than traditional halogen or incandescent lamps. Conventional light-emitting diode chips use a direct on-package (COB) technology to fix a light-emitting diode chip on an aluminum, a PCB, or a ceramic substrate, thereby having a single-sided light emission and low luminous efficiency. Another conventional packaging technology of a light-emitting diode chip is to package a chip on a glass substrate. Although the luminous efficiency of the light-emitting diode chip is improved, the heat dissipation efficiency of the glass substrate is poor, the production yield is low, and The color temperature of the light emitted from both sides of the glass substrate is different, so the technology of such a light-emitting diode wafer still needs to be improved.
請參照圖1,係顯示一種傳統之發光二極體(LED)燈具10。LED燈具10包含以傳統技術封裝之LED發光晶片11與燈殼(又稱燈罩)12,在LED發光晶片11與燈殼12之間有一間隔空間121。LED 發光晶片11所發出的光,需經過間隔空間121以及燈罩12,才能對外出光,此種出光路徑,導致燈罩12外之取光率較低。此外,因燈罩12以及其內部空間121之長距離,導致發光單元11對外散熱之散熱效果不佳,因此,還需另外設置連接於發光單元11之散熱板(未顯示)以增加散熱效率。 Referring to Figure 1, a conventional light emitting diode (LED) lamp 10 is shown. The LED lamp 10 includes an LED light-emitting chip 11 and a lamp housing (also referred to as a lamp cover) 12 packaged by a conventional technology, and a space 121 is formed between the LED light-emitting chip 11 and the lamp housing 12. led The light emitted by the illuminating wafer 11 needs to pass through the space 121 and the lamp cover 12 to emit light. This light path causes the light extraction rate outside the lamp cover 12 to be low. In addition, due to the long distance between the lampshade 12 and the internal space 121, the heat dissipation effect of the light-emitting unit 11 on the external heat dissipation is not good. Therefore, a heat dissipation plate (not shown) connected to the light-emitting unit 11 is additionally provided to increase heat dissipation efficiency.
因此,如何提供一設計簡單、生產良率高、散熱效果好、以及取光率高的燈具,為重要的關鍵。 Therefore, how to provide a lamp with simple design, high production yield, good heat dissipation effect and high light extraction rate is an important key.
為達到上述及其他目的,本創作提供一種燈殼整合型發光二極體,有別於傳統LED鋁基板散熱螢光複合樹脂,本創作LED晶粒所產生的熱由燈殼整合型發光二極體內之樹脂層直接傳導或輻射於空氣中。本創作可由發光二極體、環氧樹脂(例如但不限於)、螢光粉、奈米級散熱粉等,即可完全一體組合成燈殼整合型發光二極體。其中,散熱基板扮演樹脂燈殼的角色,燈殼亦是扮演散熱基板的角色,散熱基板與燈殼二者合而為一。 In order to achieve the above and other purposes, the present invention provides a lamp-case integrated type light-emitting diode, which is different from the conventional LED aluminum substrate heat-dissipating fluorescent composite resin, and the heat generated by the LED die is integrated by the lamp-shell integrated type light-emitting diode.

有關本創作之前述及其他技術內容、特點與功效,在以下配合參考圖式之一較佳實施例的詳細說明中,將可清楚的呈現。 The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments.
參照第2A、2B圖,其顯示根據本創作一實施例所提供之燈殼整合型發光二極體21,其中發光單元212與封裝殼體211一體成形之組裝關係。此外,第2C圖顯示燈殼整合型發光二極體21之側視示意圖,第2D圖顯示根據第2C圖中頗面線AA之剖視示意圖,第2E圖顯示根據第2D圖中之局部視示意圖。參照第2A、2B、2C、2D、2E圖,顯示本創作之一觀點所提供之燈殼整合型發光二極體21之各角度。本創作燈殼整合型發光二極體21,包含:複數個發光單元212,分別具有至少一發光單元片2121與耦接於發光單元片2121之外接導線2122;以及封裝殼體211,封裝殼體211藉由一封裝材料2111所形成,以包覆發光單元212以及其中之發光單元片2121於封裝材料2111內,發光單元片2121透過封裝材料2111,以對封裝殼體211之外部出光;其中,封裝殼體211係封裝材料2111所形成之一體固化之結構。參照第2A圖,各發光單元212之外接導線2122可包含但不限於二導電支架(如圖式中,兩凸出部份為所述之二導電支架)。此外,封裝殼體211與發光單元片2121所形成之燈殼整合型發光二極體21,其中細節,詳見於後續說明。本創作之優點,為發光單元片2121所產生之熱,可藉由發光單元212之封裝材料與封裝材料2111之直接接觸,直接由熱傳導及熱輻射方式散熱至空氣或周遭環境中,故散熱效率遠高於習知技術。此外,藉由發光單元212之封裝材料與封裝材料2111之直接接 觸,燈殼整合型發光二極體21係對外直接出光,不會受到習知技術之燈罩或燈殼的減損,因此對外出光效果亦優於習知技術。又,因發光單元片2121之出光路徑,未如先前技術般經過多個不同折射率材質之路徑與過程,本創作出光路徑僅經由同一類似材質,且出光路徑短於先前技術,因此對外出光效果極佳。 Referring to FIGS. 2A and 2B, there is shown an assembled relationship of the lamp housing integrated type light emitting diode 21 according to an embodiment of the present invention, wherein the light emitting unit 212 is integrally formed with the package housing 211. In addition, FIG. 2C shows a side view of the lamp-case integrated type light-emitting diode 21, FIG. 2D shows a schematic cross-sectional view according to the face line AA in FIG. 2C, and FIG. 2E shows a partial view according to the second figure. schematic diagram. Referring to Figures 2A, 2B, 2C, 2D, and 2E, the angles of the lamp-case integrated type light-emitting diodes 21 provided by one of the aspects of the present invention are shown. The present invention has a plurality of light-emitting diodes 212, each of which has at least one light-emitting unit 2121 and an external conductive wire 2122 coupled to the light-emitting unit chip 2121; and a package housing 211, a package housing The 211 is formed by a package material 2111 to cover the light-emitting unit 212 and the light-emitting unit 2121 in the package material 2111, and the light-emitting unit piece 2121 is transmitted through the package material 2111 to emit light to the outside of the package housing 211. The package case 211 is a structure in which the package material 2111 is formed to be solidified. Referring to FIG. 2A, the external wires 2122 of each of the light emitting units 212 may include, but are not limited to, two conductive supports (in the figure, the two protruding portions are the two conductive supports). In addition, the package housing 211 and the lamp housing integrated type light-emitting diode 21 formed by the light-emitting unit piece 2121, the details of which are described in detail in the following description. The advantage of the present invention is that the heat generated by the light-emitting unit piece 2121 can be directly radiated by heat conduction and heat radiation to the air or the surrounding environment by direct contact between the package material of the light-emitting unit 212 and the package material 2111, so the heat dissipation efficiency Far higher than the conventional technology. In addition, the packaging material of the light emitting unit 212 is directly connected to the packaging material 2111. The light-emitting integrated light-emitting diode 21 is directly emitted from the outside, and is not degraded by the lampshade or the lamp housing of the prior art, so that the external light-emitting effect is superior to the conventional technology. Moreover, due to the light path of the light-emitting unit piece 2121, the path and process of the plurality of different refractive index materials are not passed through the prior art, and the light path is only through the same similar material, and the light-emitting path is shorter than the prior art, so the light-emitting effect is external. Excellent.
參照第2E圖,根據一實施例,封裝材料2111可包含一第一奈米導熱材21111,以提升封裝材料2111之散熱效率。其中第一奈米導熱材21111於封裝材料2111中之比例介於5%至70%之間,第一奈米導熱材21111包含複數個奈米導熱粒子,其尺徑小於50奈米(nm),以降低光的散射等對出光之影響。參照下列表1,其中顯示例如當第一奈米導熱材21111於封裝材料2111中之重量比例(wt%)從0%到70%,對封裝殼體211之透光度影響有限(例如:僅從94.2%降到89.1%),但封裝殼體211之熱傳導率增加很多(例如:從0.16W/mk提高到0.57W/mk)。因此,本創作之封裝材料2111加入第一奈米導熱材21111後,封裝材料2111之熱傳導率提升達四倍之多,但透光度僅降低約5%(封裝材料2111中包含70%之第一奈米導熱材)。 Referring to FIG. 2E, according to an embodiment, the encapsulating material 2111 may include a first nano thermal conductive material 21111 to improve the heat dissipation efficiency of the encapsulating material 2111.
