Description
本創作係關於一種LED(Light-Emitting Diode，發光二極體)燈之設計，特別是關於一種發光角度大於180度之LED燈泡。This creation is about the design of an LED (Light-Emitting Diode) lamp, especially for an LED bulb with an illumination angle greater than 180 degrees.
LED是一種半導體元件，剛開始發展時期，因其發光亮度以及顏色的問題，大多使用在非照明用之光源，如指示燈等。隨著技術進步，在白光LED開始量產後，也逐漸成為照明用的光源，例如LED燈泡。而且，因為LED有低能耗、使用壽命長、光源無閃爍、低汙染等優點，因此以LED燈泡取代傳統鎢絲燈泡已經是一種趨勢了。LED is a kind of semiconductor component. At the beginning of development, it is mostly used in non-illuminating light sources, such as indicator lights, due to its brightness and color. With the advancement of technology, after the white LED has begun mass production, it has gradually become a light source for illumination, such as LED bulbs. Moreover, because LEDs have the advantages of low energy consumption, long service life, no flicker of light source, and low pollution, it has become a trend to replace traditional tungsten filament bulbs with LED bulbs.
然而LED本身的特性與傳統鎢絲燈發光特性不同，須封裝成單顆的點光源，再將一顆以上的LED設置在電路板上，所以其發光角度無法像傳統燈泡以360度發光，只有以電路板為發光平面而向電路板上方發光，因此習知LED燈泡的發光角度最大只有接近180度。However, the characteristics of the LED itself are different from those of the conventional tungsten filament lamp. They must be packaged into a single point source, and then more than one LED is placed on the circuit board, so the illumination angle cannot be 360 degrees like a conventional bulb, only The circuit board is used as a light-emitting plane to emit light above the circuit board. Therefore, the illumination angle of the conventional LED bulb is only about 180 degrees.
緣此，本創作之目的即是提供一種具有較大發光角度的LED燈泡。Therefore, the purpose of this creation is to provide an LED bulb with a large illumination angle.
本創作之另一目的是提供散熱效果更好的LED燈泡。Another purpose of this creation is to provide LED bulbs with better heat dissipation.

The figure shows a cross-sectional view of the LED bulb of the first embodiment of the present invention, and FIG. 4 shows a schematic diagram of the light irradiation angle of the LED bulb of the first embodiment of the present invention. The LED bulb 100 of the first embodiment of the present invention comprises a lamp body 1, an LED module 2, a lamp cap 3, and a lamp cover 4.
燈體1在本實施例中為一圓塔柱形之中空殼體，且為導熱及散熱好之材質(例，金屬)一體成型製成，當然，本創作不限於此，燈體也可以是方柱殼體或其他各種形狀之柱體。燈體1具有一承載部11、一承接部12、一側延伸部13以及一散熱層14。燈體1之上段為承載部11，承載部11在本實施例中為圓柱形，並具有一上承載面111及一側承載面112。上承載面111為承載部11之上表面，且承載部11於承載面111向下內凹而形成一容置槽113以置設LED模組2，承載面111具有一通孔110，供連接於LED模組2及燈頭3之間的一電線L穿過。側承載面112自上承載面111之側面而一體向下延伸，且承載部11於側承載面112沿圓柱之徑向往內縮而在承載部1之側面形成一階梯狀之容置階部114以置設LED模組2。藉由容置槽113為內凹及容置階部 114為內縮的結構，而縮小承載部11之體積，使得LED燈泡100整體之體積隨之縮小。In this embodiment, the lamp body 1 is a circular column-shaped hollow casing, and is made of a material with good heat conduction and heat dissipation (for example, metal). Of course, the creation is not limited thereto, and the lamp body may also be Square column housing or other columns of various shapes. The lamp body 1 has a carrying portion 11, a receiving portion 12, a side extending portion 13, and a heat dissipation layer 14. The upper portion of the lamp body 1 is a carrier portion 11 which is cylindrical in this embodiment and has an upper bearing surface 111 and a side bearing surface 112. The upper bearing surface 111 is an upper surface of the bearing portion 11 , and the receiving portion 11 is recessed downwardly on the bearing surface 111 to form a receiving groove 113 for arranging the LED module 2 . The bearing surface 111 has a through hole 110 for connecting to the upper surface. A wire L between the LED module 2 and the lamp cap 3 passes through. The side bearing surface 112 extends integrally downward from the side surface of the upper bearing surface 111, and the bearing portion 11 is retracted in the radial direction of the cylinder at the side bearing surface 112 to form a stepped seating step 114 on the side of the bearing portion 1. To set the LED module 2. By accommodating the groove 113 as a concave and accommodating step 114 is a retracted structure, and the volume of the carrying portion 11 is reduced, so that the overall volume of the LED bulb 100 is reduced.
承接部12具有一自側承載面112而一體向下延伸漸擴的表面，形成燈體1的中段部分，在本實施例中，承接部12為錐瓶形狀。藉著承接部12向下延伸之漸擴表面，使得燈體1與空氣的接觸面積較大，而提升散熱效果。再者，因為承接部12上窄下闊，所以上方之承載部11做得比較小，而不會擋到設置於側承載面112之LED模組發出光線，然後其發出的光線順著漸擴之表面射出，而達到大角度發光的效果。The receiving portion 12 has a self-side bearing surface 112 and integrally extends downwardly and gradually expands to form a middle portion of the lamp body 1. In the present embodiment, the receiving portion 12 has a tapered bottle shape. By the downwardly extending surface of the receiving portion 12, the contact area of the lamp body 1 with the air is large, and the heat dissipation effect is improved. Moreover, since the receiving portion 12 is narrow and wide, the upper bearing portion 11 is made relatively small, and does not block the LED module disposed on the side bearing surface 112 to emit light, and then the light emitted by it is gradually expanded. The surface is shot to achieve a large angle of illumination.
側延伸部13自承接部12而一體向下延伸，形成為燈體1的下段部分。側延伸部13具有一套設件131及一連接部132。套設件131用來固定燈罩4，以及連接部132用來連接燈頭3。連接部132在本實施例中是一連接螺紋，燈頭3具有一對應連接螺紋之接合螺紋31，連接螺紋與接合螺紋31相互螺固而使得燈體1與燈頭3接合固定，當然，亦可藉由卡合、黏合等方式。The side extension portion 13 extends integrally downward from the receiving portion 12 to form a lower portion of the lamp body 1. The side extension 13 has a set of members 131 and a connecting portion 132. The sleeve member 131 is used to fix the lamp cover 4, and the connecting portion 132 is used to connect the lamp cap 3. The connecting portion 132 is a connecting thread in the embodiment, and the base 3 has an engaging thread 31 corresponding to the connecting thread. The connecting thread and the engaging thread 31 are screwed to each other so that the lamp body 1 and the base 3 are fixedly fixed. By means of snapping, bonding, etc.
散熱層14在本實施例中是一種散熱材料塗層，塗布於燈體1之表面，當然，亦可塗布於燈體1之中空內表面(圖未示)，以提高將燈體1之熱量散熱至空氣中的效率，而有效降低LED燈泡100的溫度。In this embodiment, the heat dissipation layer 14 is a heat dissipation material coating applied to the surface of the lamp body 1. Of course, it can also be applied to the hollow inner surface of the lamp body 1 (not shown) to improve the heat of the lamp body 1. The efficiency of heat dissipation into the air effectively reduces the temperature of the LED bulb 100.
LED模組2包括一上燈板21及一軟燈板22。上燈板21包括一個以上的LED 211，在本實施例中呈圓板狀且設置於上承載面111之容置槽113，使得上燈板21於上承載面111之發光角度θ1接近180度。軟燈板22在本實施例中成環狀而設置於側承載面112之容置階部114，且軟燈板22包括複數個環型排列之LED 221，使得發光的方位角角度φ達360度以及於側承載面112 之發光角度θ2接近180度。承上所述，藉著上燈板21及軟燈板22之發光角度的疊加，使得LED模組2總發光角度達到全周光330度以上。The LED module 2 includes an upper light board 21 and a soft light board 22. The upper light board 21 includes one or more LEDs 211, which are in the shape of a disk and are disposed in the receiving groove 113 of the upper bearing surface 111, so that the light-emitting angle θ1 of the upper light-emitting board 21 on the upper bearing surface 111 is close to 180 degrees. . In the present embodiment, the flexible lamp panel 22 is annularly disposed on the receiving step 114 of the side bearing surface 112, and the flexible panel 22 includes a plurality of annular arrays of LEDs 221 such that the azimuth angle φ of the illumination reaches 360. Degree and side bearing surface 112 The illumination angle θ2 is close to 180 degrees. As described above, by superimposing the illumination angles of the upper lamp board 21 and the soft lamp board 22, the total illumination angle of the LED module 2 is more than 330 degrees of full-circumference.
燈罩4在本實施例中是一球殼狀之透光燈罩，為高散射霧面玻璃製成，使LED模組光源照射到燈罩後擴散成更柔順的光線。當然，本創作不限於此，燈罩4也可以是非球狀，例如橄欖球形、圓錐形或是有鏤空孔之設計等，而材質也可以是透明玻璃等，只要能透光即可。燈罩4具有一個開口41，開口41套設固定於套設件131而使得燈罩4罩蓋到承載部11及承接部12，即令LED模組2位於燈罩4內。燈罩4之開口41之端緣至燈罩4之發光中心的最大夾角為30度，發光中心42定義為軟燈板22上之LED 221於朝下的發光邊界線P之上方延伸交會處，而發光中心42與開口41之相反二側端緣411所夾的角度θ3即為30度(如第4圖所示)。藉此，使得燈罩4的罩覆範圍達330度，以對應LED模組2的全周光330度發光。在本實施例中，套設件131與燈罩4是採用卡合的方式固定連接，當然，本創作不限於此，也可是螺固或黏合等方式。In the embodiment, the lampshade 4 is a spherical shell-shaped translucent lampshade, which is made of high-scattering matte glass, so that the LED module light source is irradiated to the lampshade and diffused into more compliant light. Of course, the present invention is not limited thereto, and the lampshade 4 may be non-spherical, such as a football shape, a conical shape, or a hollow hole design, and the material may be transparent glass or the like as long as it can transmit light. The lamp cover 4 has an opening 41. The opening 41 is sleeved and fixed to the sleeve member 131 so that the lamp cover 4 covers the bearing portion 11 and the receiving portion 12, that is, the LED module 2 is located in the lamp cover 4. The maximum angle between the edge of the opening 41 of the lampshade 4 and the center of illumination of the lampshade 4 is 30 degrees, and the center of illumination 42 is defined as the intersection of the LED 221 on the flexible panel 22 above the downwardly illuminated boundary line P, and the illumination The angle θ3 between the center 42 and the opposite side edge 411 of the opening 41 is 30 degrees (as shown in Fig. 4). Thereby, the cover range of the lamp cover 4 is made 330 degrees, and the light is emitted at 330 degrees corresponding to the full circumference of the LED module 2. In the present embodiment, the sleeve member 131 and the lamp cover 4 are fixedly connected by means of a snap fit. Of course, the present invention is not limited thereto, and may be screwed or bonded.
根據上述之技術手段，本實施例之LED燈泡100具有全周光330度發光的效果，而其照射範圍角更大，使得LED燈泡100能適用於更多種場合。再者，LED模組2的熱量藉由與承載面111及側承載面112平面熱接觸之方式傳導至燈體1，然後經由一體成型的燈體1迅速地導熱而將熱量平均傳導至整個燈體1，再藉著燈體1為中空殼體而有內部表面及承接部12漸擴之表面而增加與空氣接觸的表面積，並且燈體1表面具有的散熱層14將燈體1與空氣之間的熱交換速率加快，從而 將熱量迅速地散熱至空氣中。藉此，使得散熱效果更好，而有效降低LED模組之溫度，且延長其使用壽命。According to the above technical means, the LED bulb 100 of the present embodiment has the effect of 330 degrees of full-circumference illumination, and the illumination range angle is larger, so that the LED bulb 100 can be applied to more kinds of occasions. Furthermore, the heat of the LED module 2 is conducted to the lamp body 1 by being in thermal contact with the plane of the bearing surface 111 and the side bearing surface 112, and then the heat is quickly transmitted through the integrally formed lamp body 1 to conduct heat evenly to the entire lamp. The body 1 further increases the surface area in contact with the air by the inner surface of the lamp body 1 and the surface of the receiving portion 12, and the heat dissipation layer 14 on the surface of the lamp body 1 connects the lamp body 1 and the air. The rate of heat exchange between them is accelerated, thereby Heat the heat quickly into the air. Thereby, the heat dissipation effect is better, and the temperature of the LED module is effectively reduced, and the service life is prolonged.
參閱第5圖所示，其係顯示本創作之第二實施例之LED燈泡之***圖。本二實施例之LED燈泡100a與第一實施例之LED燈泡100之結構大致相同，其差別在於LED燈泡100a之燈體1a側面更具有複數個散熱鰭片15，散熱鰭片15具有自燈體1a之承接部12a之側面一體向外延伸之散熱片體151，增加燈體1a與空氣接觸之表面積，使得散熱效果更好。在本實施例中，每一片散熱鰭片15相間隔環排在承接部12a之側面，其形狀配合承接部12a之漸擴表面，為向外且由上至下傾斜而延展，如此一來，使得LED模組2發出的光照射到光罩4之最底部以達到全周光330度發光的效果。當然，本創作不限於此，散熱鰭片也可以設置在側延伸部，或是散熱鰭片更可以塗布一散熱層來幫助散熱。其他則與第一實施例相同，不再贅述。Referring to Fig. 5, it is an exploded view of the LED bulb of the second embodiment of the present invention. The LED bulb 100a of the second embodiment has substantially the same structure as the LED bulb 100 of the first embodiment, and the difference is that the side of the lamp body 1a of the LED bulb 100a further has a plurality of heat dissipation fins 15, and the heat dissipation fins 15 have self-lighting bodies. The heat sink body 151 integrally extending outward from the side of the receiving portion 12a of 1a increases the surface area of the lamp body 1a in contact with the air, so that the heat dissipation effect is better. In this embodiment, each of the fins 15 is arranged on the side of the receiving portion 12a, and the shape is matched with the diverging surface of the receiving portion 12a, and is outwardly and obliquely extended from top to bottom. The light emitted by the LED module 2 is irradiated to the bottom of the reticle 4 to achieve the effect of 330 degrees of full-circumference light. Of course, the present invention is not limited thereto, and the heat dissipation fins may be disposed on the side extensions, or the heat dissipation fins may be coated with a heat dissipation layer to help dissipate heat. Others are the same as the first embodiment and will not be described again.
以上之敘述僅為本創作之較佳實施例說明，凡精於此項技藝者當可依據上述之說明而作其它種種之改良，惟這些改變仍屬於本創作之創作精神及以下所界定之專利範圍中。The above description is only for the preferred embodiment of the present invention, and those skilled in the art can make other improvements according to the above description, but these changes still belong to the creative spirit of the creation and the patents defined below.
