Description
本發明係關於一種發光二極體之燈具,尤其是一種具有全周發光的發光二極體之燈具。 The invention relates to a luminaire for a light-emitting diode, in particular to a luminaire with a full-circumference light-emitting diode.
發光二極體(Light Emitting Diode,簡稱LED)係為一種可發光的半導體電子元件。當電流流過發光二極體時,因電致發光(Electroluminescence)原理,電子與電洞在發光二極體內重合而發出單色光。近年來,由於發光二極體技術的快速進步,發光二極體已可應用於一般室內外照明。舉例來說,一發光二極體模組設於一燈泡內,當發光二極體模組通電時,此發光二極體燈泡即可作為室內照明之用。相較於一般傳統的白熾燈泡,發光二極體燈泡具有耗能低、使用壽命長、體積小、反應快等優點,因此,發光二極體燈泡開始取代傳統白熾燈泡而成為未來照明設備的主流趨勢。 A Light Emitting Diode (LED) is a light-emitting semiconductor electronic component. When a current flows through the light-emitting diode, the electron and the hole overlap in the light-emitting diode to emit monochromatic light due to the principle of electroluminescence. In recent years, due to the rapid advancement of the light-emitting diode technology, the light-emitting diode has been applied to general indoor and outdoor lighting. For example, a light-emitting diode module is disposed in a light bulb, and when the light-emitting diode module is energized, the light-emitting diode bulb can be used for indoor lighting. Compared with the traditional incandescent bulbs, LED bulbs have the advantages of low energy consumption, long service life, small size, fast response, etc. Therefore, LED bulbs have begun to replace traditional incandescent bulbs and become the mainstream of future lighting equipment. trend.
一般而言,當發光二極體的功率越高時,其所伴隨產生的熱量也越多。同時,當熱量未能有效自發光二極體排除時,發光二極體的溫度將快速升高。而高溫會嚴重影響發光二極體的壽命及發光效能。是故,於習知技術中,功率較高的發光二極體燈泡大多會設有散熱結構,散熱結構熱接 觸於發光二極體,散熱結構可適時地將發光二極體發光時所產生的熱量排除。 In general, the higher the power of the light-emitting diode, the more heat it generates. At the same time, when the heat is not effectively removed from the self-luminous diode, the temperature of the light-emitting diode will rise rapidly. The high temperature will seriously affect the life and luminous efficacy of the LED. Therefore, in the conventional technology, most of the high-power LED bulbs are provided with a heat dissipation structure, and the heat dissipation structure is thermally connected. Touching the light-emitting diode, the heat dissipation structure can timely remove the heat generated when the light-emitting diode emits light.
另外,相較於一般的白熾燈泡的鎢絲,發光二極體的發光源面積較小,即光源分佈較為集中。因此,當發光二極體作為照明用途時,於習知技術中,業者另配置一透鏡或一擴散燈罩於發光二極體上以分散光源,進而增加發光二極體的照射角度。然而,若同時增加多個透鏡或擴散燈罩,會因為發光二極體所發射的光線需要穿透多個介質而導致光能損耗增加,進而使得照明效率降低。此外,於習知技術中,業者開發出藉由擴大擴散燈罩的體積,使擴散燈罩的形狀成為四分之三球至全球,以增加發光二極體燈泡的照射角度。但上述增加擴散燈罩體積的方式中,因為一般發光二極體燈泡的總長度係為固定,當擴散燈罩體積增加時,散熱結構的體積將隨之減少。是故,當散熱結構的體積被壓縮時,發光二極體燈泡的散熱效率亦雖之降低,如此藉由擴大擴散燈罩的體積以增加照射角度的方式,卻容易導致發光二極體燈泡的照射亮度降低和使用壽命減少的問題。 In addition, compared with the tungsten filament of a general incandescent light bulb, the light-emitting diode has a small light-emitting source area, that is, the light source is relatively concentrated. Therefore, when the light-emitting diode is used for illumination, in the prior art, a lens or a diffuser is disposed on the light-emitting diode to disperse the light source, thereby increasing the illumination angle of the light-emitting diode. However, if a plurality of lenses or diffuser covers are simultaneously added, the light emitted by the light-emitting diodes needs to penetrate a plurality of media, resulting in an increase in light energy loss, thereby reducing the illumination efficiency. In addition, in the prior art, the industry has developed to increase the illumination angle of the light-emitting diode bulb by expanding the volume of the diffusion lamp cover so that the shape of the diffusion lamp cover is three-quarters of a ball to the whole world. However, in the above manner of increasing the volume of the diffusing lamp cover, since the total length of the general light-emitting diode bulb is fixed, when the volume of the diffusing lamp cover is increased, the volume of the heat dissipating structure is reduced. Therefore, when the volume of the heat dissipation structure is compressed, the heat dissipation efficiency of the light-emitting diode bulb is also reduced, so that by increasing the volume of the diffusion lamp cover to increase the illumination angle, the light-emitting diode bulb is easily irradiated. Reduced brightness and reduced life.
總合上述,習知技術中的發光二極體燈泡產生了無法在散熱以及廣角照射之間取得平衡的問題。因此,目前急需一種發光二極體燈泡,在不影響原先的散熱效率的情形下,發光二極體燈泡具有寬廣的照射角度。 In summary, the above-described light-emitting diode bulbs have a problem in that they cannot balance between heat dissipation and wide-angle illumination. Therefore, there is an urgent need for a light-emitting diode bulb, and the light-emitting diode bulb has a wide illumination angle without affecting the original heat dissipation efficiency.
有鑒於上述的問題,本發明提供一種發光二極體之燈具,藉以解決習知技術中,習知的發光二極體之燈具無法同時解決散熱以及廣角照射的問題。 In view of the above problems, the present invention provides a light-emitting diode lamp, which solves the problem that the conventional light-emitting diode lamp cannot solve heat dissipation and wide-angle illumination at the same time.

在本發明中,「燈罩400的厚度實質上自頂部410朝側部420逐漸增厚」係定義為從巨觀的角度上,燈罩400的厚度自頂部410朝向側部420逐漸增厚。頂部410的厚度大於側部420的厚度。當發光二極體模組310所發射的光線自燈罩400內的容置空間470向外穿透經過內粗糙面430時,光線會因為內粗糙面430向外發散。同時,因為燈罩400的頂部410的曲率變化較大,所以光線的折射角度較大,藉以使光線朝向側部420擴散。相較之下,側部420的厚度較頂部410薄。當發光二極體模組310所發射的光線自燈罩400內向外穿透時,因為燈罩400的側部420的曲率變化較小,所以側部420能夠增加向外射出的光線亮度。是故,藉由上述的燈罩400的厚度配置,燈罩400能夠增加發光二極體模組310的照射角度,進而達到發光二極體之燈具100全周發光的功效。 In the present invention, "the thickness of the globe 400 is substantially thickened from the top portion 410 toward the side portion 420" is defined as the thickness of the globe 400 gradually increasing from the top portion 410 toward the side portion 420 from a macroscopic point of view. The thickness of the top portion 410 is greater than the thickness of the side portions 420. When the light emitted by the LED module 310 penetrates through the inner rough surface 430 from the accommodating space 470 in the lamp cover 400, the light is diverged outward due to the inner rough surface 430. At the same time, since the curvature of the top portion 410 of the globe 400 varies greatly, the angle of refraction of the light is large, thereby diffusing the light toward the side portion 420. In contrast, the side portion 420 is thinner than the top portion 410. When the light emitted by the LED module 310 penetrates from the inside of the globe 400, since the curvature of the side portion 420 of the globe 400 is small, the side portion 420 can increase the brightness of the outwardly emitted light. Therefore, by the thickness arrangement of the lamp cover 400 described above, the lamp cover 400 can increase the illumination angle of the light-emitting diode module 310, thereby achieving the effect of illuminating the entire circumference of the light-emitting diode 100.

請參考第9圖,第9圖為本發明之第七實施例的燈罩的剖面示意圖。本實施例的元件結構與上述第一及第六實施例的元件結構類似,故相同標號代表相似結構。相較於上述的第一實施例,本實施例與上述實施例的主要差異在於燈罩407具有彼此相對的一內粗糙面430以及一外粗糙面460,內粗糙面430面向容置空間470。外粗糙面460的非平滑結構有利於光線的發散,進而達到全周發光的功效。在其他實施例中,內粗糙面430以及外粗糙面460分別係為一具有複數個微結構的表面。舉例來說,微結構可為圓弧面、凹面、環狀凸肋或環狀凹槽(未繪示)。藉由微結構發散光線,燈罩407達到增加發散光線的功效。 Please refer to FIG. 9. FIG. 9 is a cross-sectional view of a lampshade according to a seventh embodiment of the present invention. The element structure of this embodiment is similar to that of the above-described first and sixth embodiments, and the same reference numerals denote similar structures. Compared with the first embodiment described above, the main difference between the embodiment and the above embodiment is that the lamp cover 407 has an inner rough surface 430 and an outer rough surface 460 opposite to each other, and the inner rough surface 430 faces the accommodating space 470. The non-smooth structure of the outer rough surface 460 is beneficial to the divergence of light, thereby achieving the effect of full-circumferential illumination.

為求清楚理解,在本發明之圖示中,燈罩400,402~407及其厚度、內粗糙面430、圓弧面432、凹面434、環狀凸肋436、環狀凹槽438以及外粗糙面460的大小非以實際比例進行繪示。 For clarity of understanding, in the illustration of the present invention, the lampshade 400, 402-407 and its thickness, inner rough surface 430, arcuate surface 432, concave surface 434, annular rib 436, annular groove 438, and outer rough surface 460 The size is not plotted in actual scale.
綜合上述的實施例,發光二極體之燈具具有不同厚度的燈罩,以增加光線的發散角度。是以,相較於習知技術而言,本發明之實施例所揭露的發光二極體之燈具,藉由調整燈罩的厚度,以使頂部的厚度大於側部的厚度。同時燈罩的材料包含擴散粉。且燈罩可具有一內粗糙面,或是燈罩具有一外粗糙面,或是燈罩同時具有內粗糙面及外粗糙面。燈罩利用內粗糙面或外粗糙面的非平滑表面可利於光線的發散。當發光二極體模組發射光線至燈罩時,燈罩發散光線,進而增加光線的照射角度,如此解決了習知技術中的發光二極體之燈具無法在散熱與廣角照射之間取得平衡的問題。在不影響燈座體積的情況下,上述實施例的燈罩的形狀在半球型與四分之三型之間,即可達到發光二極體之燈具具有全周發光的功效。 In combination with the above embodiments, the illuminating diode lamps have lampshades of different thicknesses to increase the divergence angle of the light. Therefore, in comparison with the prior art, the illuminating diode of the embodiment of the present invention adjusts the thickness of the lamp cover so that the thickness of the top portion is greater than the thickness of the side portion. At the same time, the material of the lampshade contains diffusion powder. And the lampshade can have an inner rough surface, or the lampshade has an outer rough surface, or the lampshade has both an inner rough surface and an outer rough surface. The lampshade utilizes a non-smooth surface of the inner rough surface or the outer rough surface to facilitate the divergence of light. When the light emitting diode module emits light to the lamp cover, the lamp cover emits light, thereby increasing the illumination angle of the light, thereby solving the problem that the light-emitting diode of the prior art cannot balance between heat dissipation and wide-angle illumination. . The shape of the lampshade of the above embodiment is between the hemispherical type and the three-quarter type without affecting the volume of the lamp holder, so that the lamp of the light-emitting diode can have the effect of full-circumferential illumination.
