Description
本發明是有關於一種散熱燈殼及其製造方法與應用，且特別是有關於一種一體成型之散熱燈殼及其製造方法與應用。The invention relates to a heat-dissipating lamp housing, a manufacturing method and application thereof, and particularly to an integrally formed heat-dissipating lamp housing and a manufacturing method and application thereof.
習用鎢絲球泡燈具有一螺紋電性連接座，透過旋轉之動作便可將鎢絲球泡燈以螺接方式固定於一燈座內，並與該燈座產生電性連接，其結構簡單、安裝方便，而被廣泛應用於燈具照明。然而鎢絲需在高溫下方能發出白熾光芒，在運作期間除了光能，還會伴隨大量熱能的產生，造成能量的耗損，此外鎢絲本身易因溫度過高而燒毀，因此越來越多業者傾注心力於研發新的發光二極體球泡燈，其係保留鎢絲球泡燈的螺紋電性連接座，而以發光二極體取代鎢絲作為發光光源。發光二極體本身具有省電、高亮度、壽命長、顏色種類多等諸多優點，若再結合傳統鎢絲球泡燈之螺紋電性連接座，一方面具有安裝方便的優點，另一方面，對已有鎢絲球泡燈燈座之使用者而言，其僅須更換球泡燈之種類，不需安裝新的燈座，可減少許多花費。The conventional tungsten filament bulb lamp has a threaded electrical connection seat, and the tungsten filament bulb lamp can be screwed into a lamp holder through a rotating action, and is electrically connected with the lamp holder, and has a simple structure. It is easy to install and is widely used in luminaire lighting. However, tungsten wire needs to emit incandescent light under high temperature. In addition to light energy during operation, it will be accompanied by a large amount of heat energy, resulting in energy loss. In addition, the tungsten wire itself is easily burnt due to excessive temperature, so more and more operators Dedicated to the development of a new light-emitting diode bulb, which retains the threaded electrical connection of the tungsten filament bulb, and replaces the tungsten filament with the light-emitting diode as the light source. The light-emitting diode itself has many advantages such as power saving, high brightness, long life, and many kinds of colors. If combined with the threaded electrical connection seat of the conventional tungsten filament bulb, on the one hand, it has the advantage of convenient installation, on the other hand, For users of existing tungsten bulb lamp holders, it is only necessary to change the type of bulb lamp, and there is no need to install a new lamp holder, which can reduce the cost.
然而，發光二極體耐熱性差為眾所周知之缺失，若發光二極體的工作溫度偏高，可能造成發光亮度減弱，使用壽命衰減等問題。如何有效地將發光二極體所產生的熱量導離，一直是業者關注的焦點。為解決此缺失，通常於發光二極體燈具結構裝設一散熱燈殼，早期的散熱燈殼係將複數個散熱鰭片排列成環狀，並焊接在一金屬套筒的筒壁上，焊接的步驟不僅麻煩，且容易因空焊影響散熱效率，且焊接的製程會產生大量污染。為克服上述焊接所造成的問題，另有業者提供一種散熱燈殼，其係包含一散熱平面與複數個一體成型之散熱鰭片，再使二者以黏膠或嵌入方式結合。組裝燈具時，使散熱平面與裝設有發光二極體之光源組件接觸，發光二極體所產生之熱量先傳至散熱平面，再由散熱平面流向散熱鰭片，最後由空氣帶走。However, the poor heat resistance of the light-emitting diode is a well-known defect. If the operating temperature of the light-emitting diode is high, the brightness of the light-emitting diode may be weakened, and the service life may be attenuated. How to effectively divert the heat generated by the light-emitting diode has always been the focus of attention of the industry. In order to solve this deficiency, a heat-dissipating lamp housing is usually installed in the structure of the light-emitting diode lamp. The early heat-dissipating lamp shells are arranged in a ring shape and welded to the wall of a metal sleeve, and welded. The steps are not only cumbersome, but also easy to affect the heat dissipation efficiency due to the air welding, and the welding process generates a large amount of pollution. In order to overcome the problems caused by the above welding, another manufacturer provides a heat-dissipating lamp housing, which comprises a heat-dissipating surface and a plurality of integrally formed heat-dissipating fins, and then the two are combined in an adhesive or embedded manner. When assembling the luminaire, the heat dissipation plane is brought into contact with the light source assembly equipped with the illuminating diode, and the heat generated by the illuminating diode is first transmitted to the heat dissipating plane, and then flows from the heat dissipating plane to the heat dissipating fin, and finally taken away by the air.
然而，不論採用上述哪一種散熱燈殼，業者皆需先以不同的生產線製造散熱鰭片及散熱平面或金屬套筒，再將上述各個零件加以結合。一方面其製程繁複費工，而使生產成本居高不下，另一方面因各個零件非一體成型，各零件結合處將阻礙熱量之傳導，而造成散熱效率不彰。However, regardless of which of the above-mentioned heat-dissipating lamp envelopes is used, the manufacturer needs to first manufacture the heat-dissipating fins and the heat-dissipating planes or metal sleeves on different production lines, and then combine the above-mentioned various components. On the one hand, the process is complicated and labor-intensive, and the production cost is high. On the other hand, because the various parts are not integrally formed, the joints of the parts will hinder the conduction of heat, and the heat dissipation efficiency is not good.
因此，本發明之目的係提供一種新的散熱燈殼，有別於習用以散熱鰭片與其它零件結合之散熱燈殼，本發明之散熱燈殼係採用引伸工法製造而成，其為一體成型之結構，因其為一體成型，不需以多條生產線製造散熱燈殼之不同零件，亦無組裝不同零件之需求，因此可大幅精簡生產流程而降低生產成本，有利於燈具之大規模量產。且因其為一體成型，熱能在散熱燈殼中可暢行無阻，散熱效率佳。其在使用上，可滿足發光二極體燈具所需之散熱效率，但並不以此為限，其亦可應用於其他光源之燈具如水銀燈、鹵素燈等，具有應用多元之優點。Therefore, the object of the present invention is to provide a new heat-dissipating lamp housing, which is different from the heat-dissipating lamp housing which is conventionally used for combining heat-dissipating fins and other parts. The heat-dissipating lamp housing of the present invention is manufactured by an extension method, which is integrally formed. The structure is integrated, it does not need to manufacture different parts of the heat-dissipating lamp shell with multiple production lines, and there is no need to assemble different parts. Therefore, the production process can be greatly reduced, the production cost can be reduced, and the mass production of the lamps can be facilitated. . And because it is integrally formed, the heat energy can be unimpeded in the heat-dissipating lamp housing, and the heat dissipation efficiency is good. In use, it can meet the heat dissipation efficiency required for the light-emitting diode lamp, but it is not limited thereto. It can also be applied to lamps of other light sources such as mercury lamps, halogen lamps, etc., and has the advantages of multiple applications.

請參照第1A圖與第1B圖，第1A圖係繪示依照本發明第一態樣第一實施方式之散熱燈殼140立體圖。第1B圖係繪示第1A圖之剖面示意圖。此散熱燈殼140係採用引伸工法一體而成，包含傳導部141與筒壁142。傳導部141具有一周緣141a，傳導部係用以承載燈具之光源組件，使光源組件所產生之熱能先流向傳導部141，再由傳導部141流向筒壁142，最後由筒壁142之表面流向空氣。筒壁142具有第一端142a與第二端142b，第一端142a環繞傳導部141之周緣141a且與之完整相連，透過第一端142a完整相連之結構，使傳導部141與筒壁142之間具有優良的導熱效率，第二端142b完整相連環繞虛擬中心軸一周，透過第二端142b完整相連之結構，有利第二端142b與其他物件相結合。第二端142b之橫向截面積小於第一端142a之橫向截面積，而使散熱燈殼140形成一束縮開口之杯狀結構，此構造之用意在於當將此散熱燈殼140應用於具有電性連接座之燈具結構時，筒壁142之第二端142b鄰近電性連接座，其橫向截面積係配合電性連接座之尺寸，而第一端142a的橫向截面積越大，表示傳導部141之面積越大且筒壁142之表面積越大，越容易將光源組件所產生的熱量導離至空氣中。Referring to FIGS. 1A and 1B, FIG. 1A is a perspective view of a heat sink lamp housing 140 according to a first embodiment of the first aspect of the present invention. Fig. 1B is a schematic cross-sectional view showing Fig. 1A. The heat dissipation lamp housing 140 is integrally formed by an extension method, and includes a conductive portion 141 and a cylindrical wall 142. The conductive portion 141 has a peripheral edge 141a for carrying the light source assembly of the lamp, so that the thermal energy generated by the light source assembly first flows to the conductive portion 141, then flows from the conductive portion 141 to the cylindrical wall 142, and finally flows from the surface of the cylindrical wall 142. air. The cylindrical wall 142 has a first end 142a and a second end 142b. The first end 142a surrounds the peripheral edge 141a of the conductive portion 141 and is completely connected thereto. The first end 142a is completely connected to the structure, so that the conductive portion 141 and the cylindrical wall 142 are The second end 142b is completely connected to the virtual central axis and the second end 142b is completely connected to the second end 142b. The second end 142b is advantageously combined with other objects. The lateral cross-sectional area of the second end 142b is smaller than the lateral cross-sectional area of the first end 142a, and the heat-dissipating lamp housing 140 forms a cup-shaped structure with a bundle of openings. The purpose of this configuration is to apply the heat-dissipating lamp housing 140 to have electricity. The second end 142b of the tubular wall 142 is adjacent to the electrical connecting seat, and the transverse cross-sectional area thereof is matched with the size of the electrical connecting seat, and the transverse cross-sectional area of the first end 142a is larger, indicating the conducting portion. The larger the area of 141 and the larger the surface area of the wall 142, the easier it is to conduct heat from the light source assembly into the air.
在本實施例中，散熱燈殼140係採用鋁製成，因鋁具有良好導熱性與延展性，其導熱性可快速將光源組件之熱量導離，其延展性則有利於進行引伸工法，使其在引伸過程不易斷裂。舉凡具有良好導熱性與延展性之金屬或其他材質，皆適用於製造本發明之散熱燈殼140。在本實施例中，散熱燈殼140係呈錐狀，亦即此散熱燈殼140上與虛擬中心軸互相垂直之任一橫向截面皆為圓形，且傳導部141為一平面，此形狀較容易由引伸工法引伸而成，有利於降低製作此散熱燈殼140之時間成本。In the embodiment, the heat-dissipating lamp housing 140 is made of aluminum. Since the aluminum has good thermal conductivity and ductility, the thermal conductivity can quickly guide the heat of the light source component, and the ductility is favorable for the extension method. It is not easily broken during the extension process. Metals or other materials having good thermal conductivity and ductility are suitable for use in the manufacture of the heat sink housing 140 of the present invention. In this embodiment, the heat-dissipating lamp housing 140 is tapered, that is, any transverse cross-section of the heat-dissipating lamp housing 140 perpendicular to the virtual central axis is circular, and the conductive portion 141 is a flat surface. It is easy to be extended by the extension method, which is beneficial to reduce the time cost of manufacturing the heat dissipation lamp housing 140.
在第1B圖中，傳導部141之厚度L1大於筒壁142之厚度L2，在一實施方式中，傳導部141之厚度L1比筒壁142之厚度L2為2比1，且筒壁142之厚度L2之範圍為0.6公釐至3公釐。傳導部141係用以承載燈具之光源組件，其厚度L1越大，越容易吸收光源組件所產生之熱量，而達到良好的散熱效果，筒壁142則藉由與空氣接觸，使其熱量逸散到空氣中，因此筒壁142之散熱效果主要取決與其表面積大小，與其厚度L2較不相關，因此採用較小之厚度L2，以減輕散熱燈殼140之整體重量與材料成本。在依此實施方式之一實施例中，筒壁142之厚度L2為0.8公釐，在依此實施方式之另一實施例中，筒壁142之厚度L2為1.2公釐。In FIG. 1B, the thickness L1 of the conductive portion 141 is greater than the thickness L2 of the cylindrical wall 142. In one embodiment, the thickness L1 of the conductive portion 141 is 2 to 1 than the thickness L2 of the cylindrical wall 142, and the thickness of the cylindrical wall 142 The range of L2 is from 0.6 mm to 3 mm. The conductive portion 141 is used to carry the light source assembly of the luminaire. The larger the thickness L1 is, the easier it is to absorb the heat generated by the light source assembly, and the good heat dissipation effect is achieved, and the wall 142 is in contact with the air to dissipate the heat. In the air, the heat dissipation effect of the wall 142 is mainly determined by its surface area, and is not related to its thickness L2. Therefore, a smaller thickness L2 is used to reduce the overall weight and material cost of the heat sink casing 140. In one embodiment in accordance with this embodiment, the thickness L2 of the barrel wall 142 is 0.8 mm. In another embodiment in accordance with this embodiment, the thickness L2 of the barrel wall 142 is 1.2 mm.

A plurality of integrally connected fins 143 are stamped on the barrel wall 142 by stamping, and thus a plurality of holes 144 are formed. Care must be taken during stamping to not damage the integrity of the connection between the first end 142a and the second end 142b of the barrel wall 142. One end of the fin 143 is connected to the cylinder wall 142, and the other end may extend in the cylinder wall 142 or outside the cylinder wall 142 (not shown). If the fin 143 extends outside the cylinder wall 142, the air flowing outside the cylinder wall 142 flows. The performance is better, so that a better heat dissipation effect can be obtained, but the user may be accidentally scratched by the fin 143 when taking the cylinder wall 142. If the fin 143 is extended toward the cylinder wall 142, the user can be prevented from being The situation of scratching. In the present embodiment, the fins 143 extend into the barrel wall 142. For safety reasons, one end of the fins 143 not connected to the barrel wall 142 is designed to be curved. When the heat-dissipating lamp housing 140 is applied to the structure of the light-emitting diode lamp, the circuit control board of the structure of the light-emitting diode lamp can be installed in the heat-dissipating lamp housing 140, and a plurality of holes 144 are formed in the wall 142 of the tube. The heat generated by the circuit board is dissipated from the interior of the barrel wall 142 to the outside of the barrel wall 142.
請參照第3圖，其係繪示依照本發明第一態樣第三實施方式之散熱燈殼140局部剖面立體示意圖。利用衝孔方式於筒壁142上衝出複數個孔洞145，但需維持筒壁142第一端142a與第二端142b之相連完整性。此複數個孔洞145與第2圖中複數個孔洞144之效果相同，可使筒壁142內、外之空氣透過複數個孔洞145產生對流，有利於將筒壁142內部之熱量逸散至筒壁142外。Please refer to FIG. 3 , which is a partial cross-sectional perspective view of a heat dissipation lamp housing 140 according to a third embodiment of the first aspect of the present invention. A plurality of holes 145 are punched out of the wall 142 by punching, but the integrity of the connection between the first end 142a and the second end 142b of the wall 142 is maintained. The plurality of holes 145 have the same effect as the plurality of holes 144 in FIG. 2, and the air inside and outside the wall 142 can be convected through the plurality of holes 145, thereby facilitating the dissipation of heat inside the wall 142 to the wall. 142 outside.
請參照第4圖，其係繪示依照本發明第一態樣第四實施方式之散熱燈殼140局部剖面立體示意圖。可利用撞擊方式使筒壁142具有複數個一體相連之凸起處146，這些凸起處146之凸起方向可朝筒壁142內或朝筒壁142外(圖未示)。不論凸起處146之凸起方向為何，其目的皆用以增加筒壁142之表面積，而藉此提高散熱燈殼140導離熱量的效率。Referring to FIG. 4, a partial cross-sectional perspective view of a heat sink lamp housing 140 according to a fourth embodiment of the first aspect of the present invention is shown.
