Description

發光二極體燈具 Light-emitting diode lamp

本發明涉及一種發光二極體燈具，特別涉及一種用於戶外照明之發光二極體燈具。 The invention relates to a light-emitting diode lamp, in particular to a light-emitting diode lamp for outdoor lighting.

發光二極體作為一種高效之發光源，具有環保、亮度高、省電、壽命長等諸多特點已經被廣泛地運用於各種領域。而且，目前由發光二極體組成之模組能產生大功率、高亮度之光源，因此將廣泛地、革命性地取代白熾燈等習知光源，進而成為符合節能環保主題之主要光源。 As a highly efficient light source, the light-emitting diode has been widely used in various fields due to its environmental protection, high brightness, power saving and long life. Moreover, the module composed of the light-emitting diode can generate a high-power, high-brightness light source, and thus will replace the conventional light source such as an incandescent lamp widely and revolutionarily, and thus become the main light source that meets the theme of energy conservation and environmental protection.

隨著發光二極體或其模組之功率、亮度之增大，其產生之熱量也越來越大，為妥善解決發光二極體之發熱問題，保障發光二極體燈具之工作壽命，通常都在發光二極體模組上安裝一散熱器對其進行散熱，該二極體模組則呈水平貼置於該散熱器底部而成為平面光源。由於平面光源之照射方向單一，使燈具之照射面積有限，且不能提供多個照明角度之光源，很多情況下都難以使用戶滿意。另外，受燈具之體積限制，發光二極體模組中之發光二極體數量不可能太多，從而整個發光二極體模組發出之亮度也難以達到要求。 As the power and brightness of the LED or its module increase, the amount of heat generated is also increased, so as to properly solve the heating problem of the LED, and ensure the working life of the LED lamp, usually A heat sink is mounted on the light emitting diode module to dissipate heat, and the diode module is horizontally placed on the bottom of the heat sink to become a planar light source. Due to the single illumination direction of the planar light source, the illumination area of the luminaire is limited, and the illumination source of multiple illumination angles cannot be provided, and in many cases, it is difficult to satisfy the user. In addition, due to the volume limitation of the lamp, the number of light-emitting diodes in the LED module cannot be too much, and the brightness emitted by the entire LED module is difficult to meet the requirements.

有鑒於此，有必要提供一種照射面積及亮度較大之發光二極體燈具。 In view of this, it is necessary to provide a light-emitting diode lamp having a large irradiation area and a large brightness.

一種發光二極體燈具，包括一散熱器及一安裝於散熱器底部之發光二極體模組，該發光二極體燈具還包括安裝於散熱器頂部之另一發光二極體模組 及與散熱器頂部連接之一定位柱，一反光板安裝於定位柱上且與散熱器相隔設置。 A light-emitting diode lamp includes a heat sink and a light-emitting diode module mounted on the bottom of the heat sink, the light-emitting diode lamp further comprising another light-emitting diode module mounted on the top of the heat sink And a positioning post connected to the top of the heat sink, a reflector is mounted on the positioning post and spaced apart from the heat sink.

與習知技術相比，本發明發光二極體燈具在散熱器之底部和頂部分別設置有發光二極體模組，在不增大發光二極體燈具之體積之前提下，可增多發光二極體模組之設置，從而增大該發光二極體燈具之亮度。同時設置反光板用於反射散熱器頂部之發光二極體模組發出之光，可增大該發光二極體燈具之照射面積。 Compared with the prior art, the light-emitting diode lamp of the present invention is provided with a light-emitting diode module at the bottom and the top of the heat sink, and can be added before the volume of the light-emitting diode lamp is increased. The setting of the polar body module increases the brightness of the light emitting diode lamp. At the same time, the reflector is arranged to reflect the light emitted by the LED module on the top of the heat sink, and the illumination area of the LED lamp can be increased.

上蓋板70與下蓋板60均由玻璃或其他透明材質製成。上蓋板70其中間部分向上拱起形成圓臺狀，而外周則為圓環狀，上蓋板70之外周部分開設有與散熱器10之導熱體12上之固定部120相對應之安裝孔72。上蓋板70之中間部分與散熱器10之凸柱16之頂端相接觸，外周部分則通過螺絲等緊固件與散熱器10上之固定部120固定連接。上蓋板70用於保護安裝在安裝面15上之發光二極體模組30。下蓋板60呈圓形，其上開設有與散熱器10之導熱體12上之固定部120相對應之安裝孔62。蓋板60之尺寸與散熱器10之導熱體12上之安裝面14之尺寸相當，從而使蓋板60可剛好蓋設在安裝面14上用於保護安裝在其內之發光二極體模組20。 The upper cover 70 and the lower cover 60 are both made of glass or other transparent material. The middle portion of the upper cover plate 70 is upwardly arched to form a truncated cone shape, and the outer periphery is annular, and the outer peripheral portion of the upper cover plate 70 is provided with a mounting hole corresponding to the fixing portion 120 of the heat conductor 12 of the heat sink 10. 72. The middle portion of the upper cover 70 is in contact with the top end of the boss 16 of the heat sink 10, and the outer peripheral portion is fixedly coupled to the fixing portion 120 on the heat sink 10 by fasteners such as screws. The upper cover 70 is used to protect the LED module 30 mounted on the mounting surface 15. The lower cover 60 has a circular shape, and a mounting hole 62 corresponding to the fixing portion 120 on the heat conductor 12 of the heat sink 10 is opened. The size of the cover plate 60 is equivalent to the size of the mounting surface 14 of the heat conductor 12 of the heat sink 10, so that the cover plate 60 can be just placed on the mounting surface 14 for protecting the LED module mounted therein. 20.

定位柱40包括一圓形基座41及由基座41之中央向上延伸形成之一圓筒狀之筒體42。筒體42之外周還設置有均勻分佈之複數加強筋43。該等加強筋43豎直延伸貫穿整個筒體42之外表面。筒體42之頂端於每一加強筋43之位置設置有安裝孔430。定位柱40之基座41置於上蓋板70之中間部分之上並與散熱器10上之凸柱16固定連接。 The positioning post 40 includes a circular base 41 and a cylindrical body 42 extending upward from the center of the base 41. A plurality of reinforcing ribs 43 are evenly distributed on the outer circumference of the cylinder 42. The ribs 43 extend vertically throughout the outer surface of the barrel 42. A mounting hole 430 is provided at a position of the top end of the cylinder 42 at each of the reinforcing ribs 43. The base 41 of the positioning post 40 is placed over the intermediate portion of the upper cover 70 and is fixedly coupled to the stud 16 on the heat sink 10.

反光板50大致呈一倒置之圓錐形，其頂端置於下方與定位柱40之筒體42頂端固定連接而與散熱器10相隔設置。反光板50之頂端上設有與定位柱40之 筒體42上之安裝孔430相對應之通孔500，以供緊固件通過將反光板50固定在筒體42上。反光板50之外表面可反射發光二極體模組30發出之光。 The reflector 50 is substantially in the shape of an inverted conical shape, and its top end is placed below and fixedly connected to the top end of the cylinder 42 of the positioning post 40 to be spaced apart from the heat sink 10. The top of the reflector 50 is provided with a positioning post 40 The mounting holes 430 on the barrel 42 correspond to the through holes 500 for the fasteners to be secured to the barrel 42 by the reflector 50. The outer surface of the reflector 50 can reflect the light emitted by the LED module 30.

如圖1所示，該發光二極體燈具組裝後，發光二極體模組20發出之光可直接穿過下蓋板60照射至燈具之下方。而發光二極體模組30由於安裝在散熱器10之頂端，其發出之光向上照射並穿過上蓋板70後，可經過反光板50之反射同樣照射至燈具之下方。散熱器10可起到冷卻兩個發光二極體模組20、30之作用。由於兩個發光二極體模組20、30分別貼置在散熱器10之底、頂兩面，因此在沒有增大發光二極體體積之前提下，將發光二極體模組之設置空間增大。另外，藉由反光板50之反光作用，使得朝向發光二極體燈具下方之光線亮度及照射面積都得到加強。 As shown in FIG. 1 , after the LED package is assembled, the light emitted by the LED module 20 can be directly irradiated through the lower cover 60 to the lower side of the lamp. The light-emitting diode module 30 is mounted on the top end of the heat sink 10, and the emitted light is irradiated upward and passes through the upper cover 70, and can be irradiated to the lower side of the lamp through the reflection of the reflector 50. The heat sink 10 functions to cool the two light emitting diode modules 20, 30. Since the two LED modules 20 and 30 are respectively placed on the bottom and the top of the heat sink 10, the space of the LED module is increased without increasing the volume of the LED. Big. In addition, by the reflective action of the reflector 50, the brightness and illumination area of the light below the illuminating diode lamp are enhanced.

惟，該發光二極體燈具中之反光板50之反光面與水平面間之夾角(也即反射角度)可應要求而予以變更。另外，反光板50也不僅限於圓錐形，也可以為多面體形或者與之類似之反射面，只要能達到將發光二極體模組30發出之光向下反射之功能即可。 However, the angle between the reflective surface of the reflector 50 in the light-emitting diode lamp and the horizontal plane (ie, the angle of reflection) can be changed as required. In addition, the reflector 50 is not limited to a conical shape, and may be a polyhedral shape or a reflection surface similar thereto, as long as the function of reflecting the light emitted from the LED module 30 downward can be achieved.

綜上所述，本發明符合發明專利要件，爰依法提出專利申請。惟，以上所述者僅為本發明之較佳實施例，舉凡熟悉本案技藝之人士，在爰依本發明精神所作之等效修飾或變化，皆應涵蓋於以下之申請專利範圍內。 In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
