可將光源強光及廣角透光之透光殼 Light source with strong light source and wide-angle light transmission

本發明關於一種用於燈泡或燈的透光殼，特別是關於一種可強光並可廣角透光的透光殼。 BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a light transmissive housing for a light bulb or a lamp, and more particularly to a light transmissive housing that is glare and can be widely transmitted at a wide angle.

隨著科技的進步，照明技術亦有長足的進展，從白熾燈泡、熱陰極燈管(HCFL)、冷陰極燈管(CCFL)一直到發光二極體(LED)，各樣的光源不斷被開發出來。近來，發光二極體由於其省電、體積小、壽命長、不易破損等優點，亦取得燈具之一席領域。 With the advancement of technology, lighting technology has also made great progress. From incandescent bulbs, hot cathode lamps (HCFLs), cold cathode tubes (CCFLs) to light-emitting diodes (LEDs), various light sources are constantly being developed. come out. Recently, the light-emitting diode has obtained the field of one of the lamps due to its advantages of power saving, small size, long life, and difficulty in damage.

然而隨著各國響應綠能政策均已設定鎢絲燈泡之退場年限，LED燈泡亦逐漸納入替代傳統燈泡之換裝市場。據此，LED燈泡之使用亦逐漸顯現出與傳統鎢絲燈泡和鹵素杯燈之佈置照明的一些盲點。例如(一)在光效、壽命與散熱結構息息相關下，傳統鎢絲廣角燈泡的體積所侷限的散熱體導致E26、E27、B22型鎢絲燈泡型LED燈泡尚無法表現鎢絲燈泡的最大瓦數的亮度；(二)MR16鹵素燈泡亦同。(三)無法達到PAR系統鹵素燈泡(反光燈杯型加擴光透光殼)所呈現的中心強光及廣角透光。依上述(一)、(二)項論：原已組裝燈頭之高度，如是使用高照度燈泡，則低照度燈泡必無法呈現所需之照度。依(三)項論，PAR系統鹵素 燈泡所呈現在遠距看板之主投光及大面積暈光，能凸顯主題及陪襯畫面。而目前以PAR系統LED燈泡在亮度及照射角度及暈光面積均無法呈現。 However, as countries respond to the green energy policy have set the exit time of tungsten filament bulbs, LED bulbs are gradually included in the replacement market for traditional bulbs. Accordingly, the use of LED bulbs has gradually revealed some blind spots with the arrangement of conventional tungsten bulbs and halogen cup lamps. For example, (1) Under the relationship between light efficiency, life and heat dissipation structure, the heat dissipation body limited by the volume of the traditional tungsten wire wide-angle bulb causes the E26, E27, B22 type tungsten filament bulb type LED bulbs to fail to express the maximum wattage of the tungsten filament bulb. The brightness; (b) MR16 halogen bulbs are also the same. (3) It is impossible to achieve the central glare and wide-angle light transmission exhibited by the PAR system halogen bulb (reflector cup type plus diffused light-transmissive shell). According to the above (1) and (2) items: the height of the lamp head has been assembled. If a high-illuminance light bulb is used, the low-illuminance light bulb must not exhibit the required illumination. According to (3), PAR system halogen The bulb is presented in the main projection of the long-distance kanban and large-area glare, which can highlight the theme and the accompanying picture. At present, the LED light bulb of the PAR system cannot be presented in terms of brightness, illumination angle and blooming area.

圖1及圖2分別顯示一種習知使用發光二極體之燈泡3，其包含隔距構建之複數發光二極體(LED、SMD、晶片)301、一基板302、一散熱座303、複數散熱鰭片304及一設於該驅動器座308的驅動器305。其中，發光二極體301設置於基板302上，基板302與散熱座303連結，散熱鰭片304環設於散熱座303，驅動器305容置於燈泡3內用以驅動發光二極體301。散熱座303係分距構設複數V型槽306，V型槽306之角度係按所需發光射角而定。發光二極體301設置於V型槽306底部。燈泡3更包含一平面或內凸之殼體307設置於V型槽306頂部。據此，燈泡3雖可得到所需之射角光，但無法得到大廣角的出光。並且燈泡3亦無法達到同時具有投射光及大面積暈光的照射功能。 1 and 2 respectively show a conventional light bulb 3 using a light-emitting diode, which comprises a plurality of light-emitting diodes (LED, SMD, wafer) 301 constructed by a spacer, a substrate 302, a heat sink 303, and a plurality of heat sinks. The fin 304 and a driver 305 disposed on the driver base 308. The light-emitting diode 301 is disposed on the substrate 302. The substrate 302 is coupled to the heat sink 303. The heat sink fin 304 is disposed on the heat sink 303. The driver 305 is received in the bulb 3 to drive the LED 301. The heat sink 303 is configured to form a plurality of V-shaped grooves 306, and the angle of the V-shaped grooves 306 is determined according to the required light-emitting angle. The light emitting diode 301 is disposed at the bottom of the V-shaped groove 306. The bulb 3 further includes a planar or convex housing 307 disposed on top of the V-groove 306. Accordingly, although the bulb 3 can obtain the required angle light, it cannot obtain a large wide-angle light. Moreover, the bulb 3 cannot achieve the illumination function with both projected light and large area blooming.

圖3顯示另一習知使用發光二極體之燈泡4，其包含隔距構建之複數發光二極體(LED、SMD、晶片)401、一基板402、一散熱座403、複數散熱鰭片404、一設於該驅動器座408之驅動器405及一半圓殼體406。其中，發光二極體(LED、SMD、晶片)401設置於基板402上，且半圓殼體406設置於發光二極體401對應面。據此可得廣角均勻投射光。但限於該型LED燈泡需與鎢絲燈泡之體積相當，才能裝入傳統鎢絲燈泡之嵌燈具，而最大體積之燈體散熱結構，在光效及壽命之條件下尚無法達到如鎢絲燈泡之100W的照度(Lux)來提供閱讀所需的照射角度。 FIG. 3 shows another conventional light bulb 4 using a light-emitting diode, which comprises a plurality of light-emitting diodes (LED, SMD, wafer) 401 constructed by a spacer, a substrate 402, a heat sink 403, and a plurality of heat sink fins 404. A driver 405 and a semicircular housing 406 are disposed on the driver base 408. The light emitting diodes (LED, SMD, and wafer) 401 are disposed on the substrate 402, and the semicircular housing 406 is disposed on the corresponding surface of the light emitting diode 401. According to this, it is possible to uniformly project light at a wide angle. However, it is limited to the volume of the LED bulb to be equivalent to the volume of the tungsten bulb, so as to be embedded in the conventional tungsten bulb, and the maximum volume of the heat dissipation structure cannot reach the tungsten bulb under the conditions of light efficiency and longevity. The 100W illumination (Lux) provides the illumination angle required for reading.

因此，如何將LED(SMD、晶片)燈泡完全呈現舊有傳統燈泡之尺 寸規格、壽命、照度、射角及暈光，並符合裝有燈泡之設置點高度且得到舊有燈泡之照度，以符合使用人之：舊有的習慣照度、舊有的娛樂場所、店面及廣告看板投射光之照度及光型設計，如主光、亮度、暈光.....等，是LED業者極需面對的課題。因為如達成上述之目的，不但可完全呈現舊有的照度及暈光；不必因照度、暈光之不足，而需再加裝燈具及燈泡所帶來的損失及支出；如：燈具、LED燈泡、配線人員的人工費用，營業場所因停業施工而需付出額外的營業耗損。 Therefore, how to fully display the LED (SMD, wafer) bulbs with the old traditional bulbs Inch size, life, illumination, angle of view and halo, and meet the height of the set point of the light bulb and get the illumination of the old light bulb to meet the user's: old custom lighting, old entertainment, storefront and The illuminance and light-type design of the billboards, such as main light, brightness, and halo, are the topics that the LED industry needs to face. Because if you achieve the above objectives, you can not only fully display the old illuminance and fainting; you don't have to add luminaires and bulbs to the loss and expense caused by illuminance and fainting; such as: lamps, LED bulbs The labor costs of the wiring personnel and the additional operating expenses of the business premises due to the suspension of construction.

有鑑於上述課題，本發明之目的即在提供一種能夠強光又可廣角透光的燈泡之透光殼。為達上述目的，本發明之透光殼包含一凸鏡體以及一延伸殼體，其中該凸鏡體具有一相背設置的外上端面與內下端面，該外上端面構建一凸緣，該內下端面構建為一平面或內凹弧面，該延伸殼體具有一自該凸鏡體之外上端面外緣環繞延伸的外端面以及一與該外端面相背設置的內端面，該延伸殼體可為一斜度向外延伸亦或垂直向延伸，其延伸殼體之內端面與該凸鏡體之內下端面需構成圓弧接緣。凸鏡體之內下端面與延伸殼體之內端面設有一霧面結構。據此，不但可使光源之正投射光經由凸鏡體投射光線而形成強光，偏投射光則經由延伸殼體透射而形成廣角光。而凸鏡體之外上端面外緣和延伸殼體外端面構成圓弧接緣，以及延伸殼體之內端面與該凸鏡體之內下端面所構成圓弧接緣，則能將經凸鏡體投射的強光及經延伸殼體之透射光之間的段差改善成勻射光，並因如聚建多數LED光源時，可透過凸鏡體之內下端面之內弧面形成廣面積之聚焦於凸鏡體之強光區而達 到倍光之效果。 In view of the above problems, it is an object of the present invention to provide a light-transmitting envelope of a bulb which is capable of transmitting light with high light and wide angle. In order to achieve the above object, the light-transmitting shell of the present invention comprises a convex mirror body and an extension housing, wherein the convex mirror body has an outer upper end surface and an inner lower end surface disposed opposite to each other, and the outer upper end surface constructs a flange. The inner lower end surface is formed as a flat or concave curved surface, and the extension housing has an outer end surface extending from an outer edge of the upper end surface of the convex mirror body and an inner end surface disposed opposite to the outer end surface, The extension housing may extend outwardly or vertically in a slope, and the inner end surface of the extension housing and the inner lower end surface of the convex mirror body need to form a circular arc edge. The inner lower end surface of the convex mirror body and the inner end surface of the extension housing are provided with a matte structure. According to this, not only the positive projection light of the light source can be projected by the convex mirror body to form strong light, but the partial projection light is transmitted through the extension casing to form wide-angle light. The outer edge of the upper end surface of the convex mirror body and the outer end surface of the extension housing form a circular arc edge, and the inner end surface of the extension housing and the inner end surface of the convex mirror body form a circular arc edge, and the convex mirror can be used. The difference between the strong light projected by the body and the transmitted light passing through the extended casing is improved into uniform light, and, for example, when a plurality of LED light sources are built, a wide area of focus can be formed through the inner curved surface of the inner and lower end faces of the convex mirror body. In the strong light area of the convex mirror body To the effect of double light.

據此，可將光源之中心照度達到強光、甚至數倍強光之效果，並可形成照明所需之暈光，並因是利用光學結構達到強光，所以在所需照度的要求下，不但可減少LED之使用，更可相對減少電力之使用，且可有效地減少熱度的遞增，真正達成節能減碳的成果。 According to this, the center illuminance of the light source can achieve the effect of strong light or even several times of strong light, and can form the halation required for illumination, and because the optical structure is used to achieve strong light, so under the requirement of the required illumination, Not only can the use of LEDs be reduced, but also the use of electricity can be relatively reduced, and the increase in heat can be effectively reduced, and the result of energy saving and carbon reduction can be achieved.
