Description
本創作係有關於一種LED燈管裝置，特別是指一種發光角度大於180度之LED燈管裝置。 The present invention relates to an LED tube device, in particular to an LED tube device having an illumination angle greater than 180 degrees.
按，日光燈管是現代不可或缺的照明工具，是普遍使用的照明產品，但日光燈管的體積大，於製造、使用及棄置過程中皆會產生大量的汞污染，對於環境保護一直是潛在的重金屬污染源；再者日光燈管的使用壽命甚短，僅約1千小時，且僅能將所接收到的電能百分之十轉換為光能，百分之九十轉換為無用的熱能散失到空氣中，造成電能的耗損，如此浪費能源，著實增加自然環境的沈重負擔。 According to the fluorescent tube, it is a modern and indispensable lighting tool. It is a commonly used lighting product. However, the fluorescent tube is bulky, and it will produce a large amount of mercury pollution during manufacturing, use and disposal. It has always been a potential for environmental protection. The source of heavy metal pollution; the life of the fluorescent tube is very short, only about 1,000 hours, and only 10% of the received electric energy can be converted into light energy, and 90% is converted into useless heat to the air. In the middle, the loss of electrical energy, so much energy is wasted, and the heavy burden of the natural environment is actually increased.
為解決上述日光燈管的缺點，以及響應環保、節能減碳的要求下，由於發光二極體(LED)具有環保、省電、高效率、使用壽命長、體積小及反應快等優點，業者均積極開發出LED燈管來替代傳統的日光燈管，且漸漸普遍被使用於各類照明領域。目前較先進的LED燈管結構，主要係將半圓形散熱鋁管與相對之半圓形燈罩卡接組成一中空燈管，其內配置一LED晶片電路板，再於中空燈管內設置一LED驅動電路，據以封組成一外表具有較大散熱面積之LED燈管。唯，該習知LED燈管結構在製造及應用上仍有如下缺點： In order to solve the shortcomings of the above fluorescent tubes and the requirements of environmental protection, energy saving and carbon reduction, the LEDs have the advantages of environmental protection, power saving, high efficiency, long service life, small volume and fast response. Actively developed LED tubes to replace traditional fluorescent tubes, and gradually used in various types of lighting. At present, the more advanced LED tube structure mainly comprises a semi-circular heat-dissipating aluminum tube and a semi-circular lampshade to form a hollow lamp tube, wherein an LED chip circuit board is arranged therein, and then a hollow lamp tube is disposed in the hollow lamp tube. The LED driving circuit is sealed to form an LED tube having a large heat dissipation area. However, the conventional LED tube structure still has the following disadvantages in manufacturing and application:
1.半圓形散熱鋁管的散熱面積雖大，卻必須佔掉整個中空燈管的一半或一半以上的斷面積，這意味著光源的面積不到整個中空燈管一半，不僅只能向下發光，且小於180度發光角度；再者，半圓形散熱鋁管製造所需的金屬材料隨面積大而增多，無形中使LED燈管整體重量增加、成本提高。 1. The semi-circular heat-dissipating aluminum tube has a large heat-dissipating area, but it must occupy half or more of the entire hollow tube. This means that the area of the light source is less than half of the entire hollow tube, not only downward. Luminous, and less than 180 degrees of illumination angle; in addition, the metal material required for the manufacture of the semi-circular heat-dissipating aluminum tube increases with the area, which inevitably increases the overall weight of the LED tube and increases the cost.
2.LED燈管點亮時，LED晶片電路板與LED驅動電路所疊加的溫 度與僅LED晶片電路板之溫度，兩者溫差至少高於10℃，使得，長期下來由於工作溫度的差異、內部高溫的影響以及散熱不均的問題，容易造成LED驅動電路及LED晶粒損壞，同時LED晶粒界面溫度過高，也會導致發光效率衰減、壽命降低等問題。 2. When the LED lamp is lit, the temperature of the LED chip circuit board and the LED drive circuit are superimposed The temperature difference between the temperature and the LED chip board is at least 10 °C, which makes the LED driver circuit and LED die damage easily due to the difference of working temperature, the influence of internal high temperature and uneven heat dissipation. At the same time, the interface temperature of the LED die is too high, which may cause problems such as a decrease in luminous efficiency and a decrease in lifetime.
3.半圓形燈罩燈罩係由霧化的塑膠或壓克力材質所構成，透光性欠佳且具有炫光問題，會使照明效果大打折扣。 3. The semi-circular lampshade lampshade is made of atomized plastic or acrylic material. It has poor light transmission and glare problem, which will greatly reduce the lighting effect.
因此，如何解決高溫散熱、炫光的問題，以及提高透光性、降低整體燈管重量及有效延長元件壽命是亟待解決的問題。 Therefore, how to solve the problem of high-temperature heat dissipation and glare, as well as improving light transmittance, reducing the overall lamp weight, and effectively extending the life of components are urgent problems to be solved.
有鑑於此，本創作遂針對上述先前技術之缺失，提出一種LED燈管裝置，以有效克服上述之該等問題。 In view of this, the present invention proposes an LED lamp tube device to effectively overcome the above problems in view of the above-mentioned lack of prior art.

The hollow tube body comprises an optical resin lamp cover and a heat dissipation seat, and the heat dissipation seat is coupled to the optical resin lamp cover to form an accommodating space; wherein the optical resin lamp cover has an illumination angle greater than 180 degrees, which can be close to the characteristics of the conventional full-angle illumination.

本創作設計一種便於組裝於習用的照明燈座上，可直接取代習用日光燈管使用，進而改善傳統日光燈管的散熱效率差、照度範圍小及透光性不佳等缺點。 The design of the creation is convenient for assembly on a conventional lamp holder, and can directly replace the use of the conventional fluorescent tube, thereby improving the disadvantages of poor heat dissipation efficiency, small illumination range and poor light transmission of the conventional fluorescent tube.
請一併參閱第1圖、第2圖及第3圖，第1圖為本創作之立體圖，第2圖為本創作之分解圖，第3圖為第1圖沿A-A剖面線所取之剖視圖。首先，先說明本創作之組成結構及其組裝方式，LED燈管裝置在此係設計為長條型燈管，其包括一中空管體10、一散熱片12、至少一LED模組14、二端蓋16及二LED驅動器18。中空管體10包含一光學樹脂燈罩22及一散熱座24，散熱座24具有一安裝面242，散熱座24係設計為鋁擠型的半圓形中空管，其平面作為安裝面242，半圓形中空管的弧面244外側壁具有複數個散熱鰭片246。散熱片12係設於安裝面242上，且散熱片12的長度略小於安裝面242；再將LED模組14緊貼設於散熱片12上，LED模組14較佳設計為LED燈條，其長度設計與散熱片12相同。 Please refer to Figure 1, Figure 2 and Figure 3 together. Figure 1 is a perspective view of the creation, Figure 2 is an exploded view of the creation, and Figure 3 is a cross-sectional view taken along line AA of Figure 1. . First, the composition of the present invention and its assembly method are first described. The LED tube device is designed as a long tube, which comprises a hollow tube body 10, a heat sink 12, at least one LED module 14, Two end caps 16 and two LED drivers 18. The hollow tube body 10 includes an optical resin lamp cover 22 and a heat dissipation seat 24. The heat dissipation seat 24 has a mounting surface 242. The heat dissipation seat 24 is designed as an aluminum-extruded semi-circular hollow tube, and its plane serves as a mounting surface 242. The outer surface of the curved surface 244 of the semicircular hollow tube has a plurality of fins 246. The heat sink 12 is disposed on the mounting surface 242, and the length of the heat sink 12 is slightly smaller than the mounting surface 242. The LED module 14 is closely attached to the heat sink 12, and the LED module 14 is preferably designed as an LED light strip. The length is the same as that of the heat sink 12.
接續，光學樹脂燈罩22係搭配散熱座24的造型，設計為圓弧形光學樹脂燈罩，並裝設於安裝面242上，據以形成一容置空間26。值得注意的是，為了增加照度範圍以及減輕整體重量，在此散熱座24的弧面面積是遠小於光學樹脂燈罩22，且光學 樹脂燈罩22之發光角度大於180度。其中，散熱座24之安裝面242兩側分別設有一鳩尾槽248，光學樹脂燈罩22之底端兩側分別設有一鳩尾榫222，組裝時，將光學樹脂燈罩22先自散熱座24之一端置入，讓鳩尾榫222對應鳩尾槽248內卡接之後，沿著鳩尾槽248水平移動，直至光學樹脂燈罩22完全固定結合於散熱座24上。由於光學樹脂燈罩22係為圓弧形光學樹脂燈罩，故光學樹脂燈罩22與安裝面242之間，據以形成容置空間26，且散熱片12及LED模組14皆位於容置空間26內。 In the continuation, the optical resin lamp cover 22 is matched with the shape of the heat sink 24, and is designed as a circular arc-shaped optical resin lamp cover, and is mounted on the mounting surface 242 to form an accommodation space 26. It is worth noting that in order to increase the illumination range and reduce the overall weight, the arc surface area of the heat sink 24 is much smaller than the optical resin lamp cover 22, and the optical The resin lamp cover 22 has an illumination angle greater than 180 degrees. A dovetail 248 is disposed on each side of the mounting surface 242 of the heat sink 24, and a dovetail 222 is respectively disposed on both sides of the bottom end of the optical resin lamp cover 22. When assembled, the optical resin lamp cover 22 is first disposed from one end of the heat sink 24 After the dovetail 222 is engaged with the dovetail groove 248, it is horizontally moved along the dovetail groove 248 until the optical resin lamp cover 22 is completely fixedly coupled to the heat sink 24. The optical resin lamp cover 22 is a circular arc-shaped optical resin lamp cover. Therefore, the accommodating space 26 is formed between the optical resin lamp cover 22 and the mounting surface 242, and the heat sink 12 and the LED module 14 are located in the accommodating space 26 . .
接續，將二端蓋16分別套設於中空管體10之兩端，二端蓋16分別包含一套管162及一封蓋164，封蓋164設有二電極端子166，套管162之一端套設於中空管體10，另一端套設封蓋164。詳言之，套管162設計短版的圓弧形的中空套管，其平面具有一嵌槽1622，其圓弧形面積略大於光學樹脂燈罩22，且套管162之底端兩側同樣設有鳩尾榫，套管162能夠對應置入安裝面242的鳩尾槽248內，使得二套管162分別能夠套設於光學樹脂燈罩22之兩端並緊配合固定；此時二套管162與光學樹脂燈罩22套合後加起來的總長度與散熱座24相同。接著將二LED驅動器18分別設於二端蓋16的套管162內，並將二絕緣墊28分別嵌入於套管162之嵌槽1622內，且絕緣墊28係緊鄰配置於LED驅動器18，二LED驅動器18係利用至少二導線30穿設於散熱座24的半圓形中空管內而彼此電性連接；最後將封蓋164利用螺栓168固定於散熱座24的螺孔249中，使得二封蓋164的二電極端子166分別電性連接二LED驅動器18，如此即可組裝完成LED燈管裝置。 The two end caps 16 are respectively sleeved on the two ends of the hollow tube body 10. The two end caps 16 respectively include a sleeve 162 and a cover 164. The cover 164 is provided with two electrode terminals 166, and the sleeve 162 One end is sleeved on the hollow tube body 10, and the other end is sleeved with a cover 164. In detail, the sleeve 162 is designed with a short circular arc-shaped hollow sleeve having a groove 1622 in a plane whose arc-shaped area is slightly larger than the optical resin lamp cover 22, and the bottom ends of the sleeve 162 are also provided on both sides. With the dovetail, the sleeve 162 can be inserted into the dovetail groove 248 of the mounting surface 242, so that the two sleeves 162 can be respectively sleeved on both ends of the optical resin lamp cover 22 and tightly fitted; The total length of the resin lamp cover 22 after being assembled is the same as that of the heat sink 24. Then, the two LED drivers 18 are respectively disposed in the sleeve 162 of the two-end cover 16, and the two insulating pads 28 are respectively embedded in the slots 1622 of the sleeve 162, and the insulating pads 28 are disposed adjacent to the LED driver 18, The LED driver 18 is electrically connected to each other by using at least two wires 30 passing through the semicircular hollow tube of the heat sink 24; finally, the cover 164 is fixed to the screw hole 249 of the heat sink 24 by bolts 168, so that The two electrode terminals 166 of the cover 164 are electrically connected to the two LED drivers 18, respectively, so that the LED lamp device can be assembled.
瞭解上述LED燈管裝置的結構之後，可將LED燈管裝置裝設在照明燈座上，使二端蓋16之二電極端子166接觸照明燈座上的電源線路而形成接觸導通。請同時參閱第2圖及第4圖，第4圖為本創作於照明時之剖視圖。於使用時，藉由二電極端子166傳導一電力至二LED驅動器18及LED模組14，由LED驅動器18驅動LED模組14作動，LED模組14即可投射一光源經光學樹脂燈罩22至外。由於LED驅動器18及LED模組14於運作時會產生高 溫，藉由本創作之設計巧思，二絕緣墊28能夠直接將LED驅動器18產生的高溫傳導至散熱座24，經其弧面244的此些散熱鰭片246快速將熱能傳導至空氣中；同時，散熱片12能夠直接將LED模組14產生的高溫傳導至散熱座24，經其弧面244的此些散熱鰭片246快速將熱能傳導至空氣中，如此一來，能夠確保LED驅動器18及LED模組14在低溫環境中正常的運作，以延長使用壽命；進而解決習知的燈管內部蓄熱或是局部熱疊加而造成電子元件的損壞問題。 After understanding the structure of the LED lamp device, the LED lamp device can be installed on the lamp holder, and the two electrode terminals 166 of the two end caps 16 are in contact with the power line on the lamp socket to form a contact conduction. Please also refer to Figure 2 and Figure 4, which is a cross-sectional view of the creation of the lighting. In use, the second electrode terminal 166 conducts a power to the two LED driver 18 and the LED module 14, and the LED driver 14 drives the LED module 14 to operate. The LED module 14 can project a light source through the optical resin lamp cover 22 to outer. Since the LED driver 18 and the LED module 14 operate high during operation By the design of the present invention, the two insulating pads 28 can directly conduct the high temperature generated by the LED driver 18 to the heat sink 24, and the heat radiating fins 246 of the curved surface 244 rapidly conduct heat energy into the air; The heat sink 12 can directly conduct the high temperature generated by the LED module 14 to the heat sink 24, and the heat radiating fins 246 of the curved surface 244 can quickly transfer the heat energy to the air, thereby ensuring the LED driver 18 and The LED module 14 operates normally in a low temperature environment to prolong the service life; thereby solving the problem of damage to electronic components caused by conventional heat storage inside the lamp or local thermal superposition.
值得注意的是，為了使光學樹脂燈罩22之發光角度大於180度，係利用光學級的樹脂材料以及加入擴散粒子，並經拉絲處理以形成具高透光性及能將光源均勻擴散的功效，可讓光學樹脂燈罩22接近材料極限的94%透光率，擴散粒子的折射率為1.4~1.5，且光學樹脂燈罩22的內側壁具有複數個波浪型凹槽224，能夠降低整體平均厚度及重量，又可提高透光性之功效及維持原有的結構強度；再者，LED模組14是使用可適用此折射率的LED晶粒，其發光角度為120度。由於光學樹脂燈罩22的弧面面積遠大於散熱座24(例如光學樹脂燈罩22所佔用弧面面積為中空管體10總體積七成以上)；因此，當LED模組14投射光源時，波浪型凹槽224可引導光源之光行走路徑，且能減少內部的光線折射與繞射，並配合大角度光學樹脂燈罩22的結構特性，讓光源被引導至大於180的發光角度，並經光學樹脂燈罩22照射至外時，能夠產生最大程度的照度，近似於傳統日光燈管的全角度發光，且有效地將光源均勻分配至LED燈管裝置四周，同時解決習知LED燈管會有炫光及光源損失的問題；當然，本創作之散熱性亦更優於傳統同時日光燈管或LED燈管。 It should be noted that in order to make the optical resin lamp cover 22 have an illumination angle greater than 180 degrees, an optical grade resin material and a diffusion particle are added, and the wire is processed to form a high light transmittance and a uniform diffusion of the light source. The optical resin lamp cover 22 can be made close to the material limit of 94% transmittance, the diffusion particles have a refractive index of 1.4 to 1.5, and the inner side wall of the optical resin lamp cover 22 has a plurality of wave-shaped grooves 224, which can reduce the overall average thickness and weight. Moreover, the effect of light transmission can be improved and the original structural strength can be maintained; in addition, the LED module 14 is an LED die that can be applied to the refractive index, and has an illumination angle of 120 degrees. Since the arc surface area of the optical resin lamp cover 22 is much larger than the heat sink 24 (for example, the arc surface area occupied by the optical resin lamp cover 22 is 70% or more of the total volume of the hollow pipe body 10); therefore, when the LED module 14 projects the light source, the wave The groove 224 can guide the light traveling path of the light source, and can reduce the internal light refraction and diffraction, and cooperate with the structural characteristics of the large-angle optical resin lamp cover 22 to allow the light source to be guided to an illumination angle greater than 180, and through the optical resin. When the lamp cover 22 is irradiated to the outside, it can generate the maximum illumination, which is similar to the full-angle illumination of the conventional fluorescent tube, and effectively distributes the light source evenly around the LED tube device, and solves the problem that the conventional LED tube has glare and The problem of loss of light source; of course, the heat dissipation of this creation is also better than the traditional simultaneous fluorescent tube or LED tube.
綜上所述，本創作能夠將內部會產生高溫的元件均勻且快速地傳導至外，可有效提高散熱效果，並利用發光角度大於180度的光學樹脂燈罩來提高照度範圍及高透光率之功效。此外，散熱座設計為中空管體，而光學樹脂燈罩的內側壁設有複數個波浪型凹槽，此結構設計不僅能降低整體重量及製造成本，又 能達到高散熱性、照度範圍大，以及可解決內部光線折射、繞射所產生光源損失的問題，極具市場競爭優勢。 In summary, the present invention can uniformly and quickly conduct components that generate high temperature inside, can effectively improve the heat dissipation effect, and utilize an optical resin lampshade with an illumination angle greater than 180 degrees to improve the illumination range and high transmittance. efficacy. In addition, the heat sink is designed as a hollow tube body, and the inner side wall of the optical resin lamp cover is provided with a plurality of wave-shaped grooves, which can not only reduce the overall weight and manufacturing cost, but also reduce the overall weight and manufacturing cost. It can achieve high heat dissipation, large illumination range, and can solve the problem of internal light refraction and light source loss caused by diffraction, which is very competitive in the market.
