Description
本創作係有關於一種組合二次光學之COB封裝照明裝置；特別是指一種設置在電路板上的發光晶片(或LED模組)的光線發射系統之導光裝置複合設計，使光線的放射在導光裝置之間產生更理想的輸出配置作用之新型。 The present invention relates to a COB package lighting device combining secondary optics; in particular, a composite design of a light guiding device of a light emitting system (or LED module) disposed on a circuit board, so that the light is emitted A new type of output configuration between the light guiding devices is more desirable.
將晶片(或裸晶)黏附在一電路板(PCB)上，並且使晶片的導線焊接在該電路板的焊墊，然後封裝一膠體(例如，矽酮膠層(silicone)、PC、EPOXY、壓克力或玻璃材質製成)包覆該晶片和導線，形成發光光源之COB(chip on board；係指一種將打線和固膠作業轉移到電路板上的製程)照明裝置，係已為習知技藝。COB照明裝置具有較習知照明裝置理想的光效、壽命、製造成本等優點；因此，已被廣泛應用在照明、航行、指示燈等方面。 The wafer (or bare crystal) is adhered to a circuit board (PCB), and the wire of the wafer is soldered to the pad of the circuit board, and then a colloid is encapsulated (for example, silicone, PC, EPOXY, Acrylic or glass material) coating the wafer and the wire to form a COB (chip on board; refers to a process for transferring the wire bonding and fixing work to the circuit board) of the illuminating light source. Knowing skills. The COB lighting device has the advantages of ideal light efficiency, longevity, manufacturing cost and the like of the conventional lighting device; therefore, it has been widely used in lighting, navigation, indicator lights and the like.
一個有關這類COB照明裝置在結構設計和應用方面的課題是，習知技藝的膠體包覆光源的封裝形狀係成頂部平面或半球形的型態；在膠體成頂部平面的型態中，當光源發射出的光線角度(或稱發散角度)較小(例如，小於40°或45°)時，光線仍可折射輸出；當光線發散角度大於46°時，其光線係在該膠體內部形成全反射，而無法折射輸出的情形。在膠體成半球形的型態中，光線的發散角度可達120°以上；甚至成發散型態輸出。但是，就像那些熟習此技藝的人所知悉，它無法應用在某些需要特 定角度或窄角度光線輸出的場合使用；例如，指示、景觀或水族照明…等場合，而這種情形並不是我們所期望的。 A subject related to the structural design and application of such COB lighting devices is that the package shape of the colloid-coated light source of the prior art is in the form of a top plane or a hemispherical shape; in the form in which the colloid is in the top plane, When the light source emits a small angle of light (or a divergence angle) (for example, less than 40° or 45°), the light can still refract the output; when the light divergence angle is greater than 46°, the light is formed inside the colloid. Reflection, but not the case of the output. In the form in which the colloid is hemispherical, the divergence angle of the light can reach 120° or more; even into a divergent form output. However, as those familiar with this skill know, it cannot be applied to certain needs. Use in situations where angled or narrow-angle light output is used; for example, indications, landscapes, or aquarium lighting, etc., and this is not what we would expect.
為了改善所述使COB照明裝置適合那些特定應用型態的課題，習知技藝也已揭露了一種使該膠體具有特定構形的COB照明裝置；例如，台灣第101201210號「COB封裝之LED裝置」專利案，係提供了一個可行的實施例。在所揭示的實施中，係使該膠體形成一凸柱的構形包覆光源。也就是說，該膠體係一體成型的封裝在該光源上；包括一成柱體形狀的台部，和一位在台部頂面，成半球形的凸弧部的結構型態。 In order to improve the problem of adapting the COB lighting device to those specific application types, the prior art has also disclosed a COB lighting device that has a specific configuration of the colloid; for example, Taiwan No. 101201210 "COB packaged LED device" The patent case provides a possible embodiment. In the disclosed embodiment, the colloid is formed into a configuration of a stud to cover the light source. That is to say, the glue system is integrally molded on the light source; and includes a column portion in the shape of a cylinder, and a structural form of a convex portion having a hemispherical shape on the top surface of the table portion.
代表性的來說，這些參考資料顯示了在有關COB照明裝置或其相關結合組件在使用和結構設計方面的情形。如果重行設計考量該COB照明裝置和相關組件結構，以及上述的應用情形，使其不同於習用者，將可改變它的使用型態，而有別於舊法；實質上，不僅可改變光源照度之配置型態(或形狀)和光源發散角度；並且，改善習知技藝光學照度不均勻等情形。更進一部的使它的光照形狀被重新分配，提高發光效果；或使其構造不同於習用者，而增加它的應用範圍(例如，使該COB照明裝置可應用在上述那些特定場合)等手段，而這些課題在上述的參考資料中均未被具體顯示或揭露。 Typically, these references show the use and structural design of the COB lighting fixture or its associated bonding components. If the re-design considers the structure of the COB illuminating device and related components, and the above-mentioned application situation, making it different from the conventional one, it will change its usage type, which is different from the old method; in essence, it can not only change the illumination of the light source. The configuration type (or shape) and the light source divergence angle; and, the improvement of the optical illuminance of the conventional technique is uneven. Further, the light shape is redistributed to improve the illuminating effect; or the structure is different from the conventional one, and the application range thereof is increased (for example, the COB illuminating device can be applied to those specific occasions). None of these topics have been specifically shown or disclosed in the above references.

1.當該二次光學20(或導光部25)距離光源12較近(例如，約1mm)時，其接受光源12的發散角度較大(約±35°~±45°)。當該二次光學20(或導光部25)距離光源12較遠(例如，約7.7mm)時，其接受光源12的發散角度較小(約±3.5°)。 1. When the secondary optics 20 (or the light guiding portion 25) is closer to the light source 12 (for example, about 1 mm), it receives a larger divergence angle of the light source 12 (about ±35° to ±45°). When the secondary optics 20 (or the light guiding portion 25) is farther from the light source 12 (e.g., about 7.7 mm), it receives a smaller divergence angle (about ± 3.5°) from the light source 12.

The COB package illuminating device and related component structure have been redesigned; for example, the COB illuminating device is combined with the secondary optics 20 forming the array structure, allowing the light source 12 to pass through the primary optics of the colloid 11 and The secondary optical action of the light guiding portions 25 and 26 is significantly different from that of the conventional method in which the light source only encapsulates the colloid.
2.該光源12經過導光部25、26的二次光學作用，進一步使它的光照形狀被重新分配，讓該COB照明裝置可依據不同場合(例如，某些需要特定角度或窄角度光線輸出的場合)，應用在指示、航行、景觀或水族照明…等場合，而使它的應用情形不同於習用者；並且，改變了它的使用型態，而有別於舊法。 2. The light source 12 passes through the secondary optics of the light guiding portions 25, 26 to further redistribute its illumination shape, so that the COB illumination device can be used according to different occasions (for example, some need a specific angle or a narrow angle of light output) In the case of indications, navigation, landscape or aquarium illumination, etc., the application situation is different from the conventional one; and it changes its use type, which is different from the old one.
3.該COB封裝照明裝置組合二次光學20的結構組織，不僅提高它的發光效果達到100 lm/W；並且，使其光照分佈均勻；以及，該重新分配的光照形狀也增加了它的應用範圍，實質上，也改善了習知結構的光源發散角度小、光學照度不均勻等情形。 3. The COB package illuminating device combines the structural structure of the secondary optics 20 to not only increase its illuminating effect to 100 lm/W; and, to make its illumination distribution uniform; and the redistributed illumination shape also increases its application.
