發光二極體燈具Light-emitting diode lamp

本發明是有關於一種發光二極體(LED)燈具,特別是指一種可以增加出光角度的發光二極體燈具。The invention relates to a light-emitting diode (LED) lamp, in particular to a light-emitting diode lamp which can increase the light-emitting angle.

由於發光二極體具有省電、使用壽命長及環保的優點,已逐漸應用普及於一般的照明領域。Since the light-emitting diode has the advantages of power saving, long service life and environmental protection, it has been gradually applied to the general lighting field.

然而,在燈泡領域,目前仍以白熾燈為主流,這是因為現有用於燈泡的發光二極體之出光角度約為120度,使得其燈泡的出光角度也約為120度,而相較於一般白熾燈的出光角度則明顯較小。現有一種燈泡結構,其利用長柱形的導光體來增加照射角度。但是長柱形的導光體使得光線傳導距離很長,有可能造成光線損耗而降低出光效率,故仍有改進的空間。However, in the field of light bulbs, incandescent lamps are still the mainstream, because the light-emitting diodes used in light bulbs have an exit angle of about 120 degrees, so that the light-emitting angle of the bulb is also about 120 degrees, compared to Generally, the angle of light emitted by incandescent lamps is significantly smaller. There is a bulb structure that utilizes a long cylindrical light guide to increase the angle of illumination. However, the long cylindrical light guide body makes the light transmission distance long, which may cause light loss and reduce light extraction efficiency, so there is still room for improvement.

因此,如何增加發光二極體燈泡的出光角度,仍是目前需要克服的問題。Therefore, how to increase the light-emitting angle of the light-emitting diode bulb is still a problem that needs to be overcome at present.

因此,本發明之目的,即在提供一種可以增加出光角度之發光二極體燈具。Accordingly, it is an object of the present invention to provide a light-emitting diode lamp that can increase the angle of light exiting.

於是,依據本發明之一較佳實施例,本發明發光二極體燈具,包含一燈座、一透光燈罩、一發光模組及一導光件。燈座與透光燈罩結合,並共同界定一容置空間,燈座具有一凸伸於容置空間中的平台部。發光模組設於燈座的平台部上,包括一電路板及至少一設於電路板的發光二極體。導光件設於平台部上並覆蓋發光模組,且導光件的外徑大於平台部的外徑。Thus, in accordance with a preferred embodiment of the present invention, a light-emitting diode lamp of the present invention includes a lamp holder, a light-transmitting lamp cover, a light-emitting module, and a light guide member. The lamp holder is combined with the light-transmitting lamp cover and defines a receiving space. The lamp holder has a platform portion protruding in the accommodating space. The light emitting module is disposed on the platform portion of the lamp socket, and includes a circuit board and at least one light emitting diode disposed on the circuit board. The light guiding member is disposed on the platform portion and covers the light emitting module, and the outer diameter of the light guiding member is larger than the outer diameter of the platform portion.

依據本發明之較佳實施例具有以下之功效,發光模組設於平台部,藉由導光件增加發光模組射出光線的折射角度以使光線可由導光件的側面出光,進而射出透光燈罩,因而能提高發光二極體燈具整體的出光角度。According to a preferred embodiment of the present invention, the illumination module is disposed on the platform portion, and the light guide member increases the refraction angle of the light emitted by the illumination module to enable the light to be emitted from the side of the light guide member, thereby emitting light. The lampshade can thus improve the overall light-emitting angle of the light-emitting diode lamp.

有關本發明之前述及其他技術內容、特點與功效,在以下配合參考圖式之五個較佳實施例的詳細說明中,將可清楚的呈現。The foregoing and other technical aspects, features and advantages of the present invention will be apparent from the Detailed Description of the <RTIgt;

在本發明被詳細描述之前,要注意的是,在以下的說明內容中,類似的元件是以相同的編號來表示。Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

參閱圖1與圖2,本發明發光二極體燈具之第一較佳實施例,包含一燈座1、一透光燈罩2、一發光模組3及一導光件4。Referring to FIG. 1 and FIG. 2, a first preferred embodiment of a light-emitting diode lamp of the present invention comprises a lamp holder 1, a light-transmitting lamp cover 2, a light-emitting module 3 and a light-guiding member 4.

燈座1具有一基部11、一由基部11頂側111凸出一定高度的平台部12及一設於基部11底側112的連接部13。透光燈罩2與燈座1的基部11結合並共同界定出一容置空間21,而且透光燈罩2還具有一與燈座1相接的結合部22。燈座1內部可供設置驅動電路單元(未圖示)與發光模組3電性連接,且基部11具有環繞於外側的多數個散熱鰭片113,可增加發光模組3的散熱效能,此外,基部11與平台部12均可由金屬製成,可以達到良好的散熱效果。連接部13用以與外部電路電性連接。The socket 1 has a base portion 11, a platform portion 12 projecting from the top side 111 of the base portion 11 by a certain height, and a connecting portion 13 provided on the bottom side 112 of the base portion 11. The light-transmitting lamp cover 2 is combined with the base portion 11 of the lamp holder 1 and defines an accommodation space 21, and the light-transmitting lamp cover 2 further has a joint portion 22 which is in contact with the lamp holder 1. The lamp holder 1 can be provided with a driving circuit unit (not shown) electrically connected to the light-emitting module 3, and the base portion 11 has a plurality of heat-dissipating fins 113 surrounding the outer side, which can increase the heat-dissipating performance of the light-emitting module 3, The base 11 and the platform portion 12 can both be made of metal, and can achieve a good heat dissipation effect. The connecting portion 13 is for electrically connecting to an external circuit.

發光模組3設於燈座1的平台部12上並位於容置空間21內,包括一設置在平台部12的電路板31及多數個設於電路板31且可朝上發光的發光二極體32,發光二極體32呈環形排列間隔分佈於電路板31。藉由平台部12使發光模組3相較於基部11的頂側111高出一特定距離H,亦即,特定距離H由平台部12的高度加上電路板31的高度所構成,也就是電路板31表面與基部11的頂側111之間的距離。在本實施例中,透光燈罩2的結合部22與基部11的頂側111位於大致相同的水平位置,所以發光模組3的水平位置高於透光燈罩2的結合部22之水平位置(高出特定距離H),藉此避免燈座1遮擋由導光件4導出而朝斜下照射的光線,導光件4在下文中再詳細說明。較佳地,發光模組3位於透光燈罩2最大直徑所在的高度位置上而可達最佳之出光角度。特定距離H的實際尺寸可介於10至12mm,在本實施例,特定距離H為11.6mm。The light-emitting module 3 is disposed on the platform portion 12 of the socket 1 and located in the accommodating space 21, and includes a circuit board 31 disposed on the platform portion 12 and a plurality of light-emitting diodes disposed on the circuit board 31 and capable of emitting upward The body 32 and the light emitting diodes 32 are arranged on the circuit board 31 in a ring-shaped arrangement. The light-emitting module 3 is raised by the platform portion 12 by a specific distance H from the top side 111 of the base portion 11, that is, the specific distance H is formed by the height of the platform portion 12 plus the height of the circuit board 31, that is, The distance between the surface of the circuit board 31 and the top side 111 of the base 11. In this embodiment, the joint portion 22 of the light-transmitting lamp cover 2 is located at substantially the same horizontal position as the top side 111 of the base portion 11 , so that the horizontal position of the light-emitting module 3 is higher than the horizontal position of the joint portion 22 of the light-transmitting lamp cover 2 ( A certain distance H) is raised, thereby preventing the lamp holder 1 from blocking the light that is led downward by the light guide 4, and the light guide 4 will be described in detail below. Preferably, the light-emitting module 3 is located at a height position where the maximum diameter of the light-transmitting lamp cover 2 is located to achieve an optimum light-emitting angle. The actual size of the specific distance H may be between 10 and 12 mm, and in the present embodiment, the specific distance H is 11.6 mm.

導光件4設於燈座1的平台部12並位於容置空間21內且覆蓋發光模組3。導光件4具有一底面41、一相對底面41的頂面42、一連接底面41與頂面42的側面43,及多數個設於底面41以對應容置各發光二極體32的曲面凹穴44,曲面凹穴44較佳為半圓形,而可使發光二極體32所發出的光均可以法線方向垂直進入導光件4而不會造成折射,降低光損耗。在本實施例,導光件4以俯視觀之呈圓型輪廓。頂面42具有一平面區421,及位於平面區421周緣的一曲面區422,頂面42的平面區421與底面41平行且大小相等。側面43具有一由底面41往外漸往上斜向延伸的斜面區431,及一由斜面區431頂緣直立往上延伸連接曲面區422底緣的外環面區432。曲面區422、斜面區431及外環面區432皆呈環狀,外環面區432圍繞界定出導光件4的外徑D1。導光件4的底面41範圍涵蓋平台部12與電路板31,亦即,平台部12與電路板31的外圍不超出導光件4的底面41涵蓋的範圍,較佳地,導光件4的外徑D1可為平台部12外徑D2的1.1至5倍,使得發光二極體32發射的光線皆能先進入導光件4,使出光均勻,在本實施例,導光件4的外徑D1為50mm,平台部12外徑D2為35mm。並且利用曲面區422增加光線的折射角度,以及利用斜面區431破壞全反射,使光線可由斜面區431出光。以實際尺寸而言,曲面區422在一縱向截面上(如圖2所示)可為錐形常數(conic parameter)介於0.1至0.9的錐角,或者,可為曲率半徑介於1至5mm的圓角,在本實施例為錐形常數0.4的錐角。斜面區431的斜切部分相對於底面41所在平面的夾角A可介於20度至60度,在本實施例為28.1度。導光件4的厚度(底面41與頂面42的平面區421之間的距離)可介於5至20mm,在本實施例為8.5mm。The light guide 4 is disposed on the platform portion 12 of the socket 1 and located in the accommodating space 21 and covers the illuminating module 3 . The light guide member 4 has a bottom surface 41, a top surface 42 opposite to the bottom surface 41, a side surface 43 connecting the bottom surface 41 and the top surface 42, and a plurality of curved surfaces disposed on the bottom surface 41 for accommodating the respective LEDs 32. The cavity 44 and the curved cavity 44 are preferably semi-circular, so that the light emitted by the LED 32 can enter the light guide 4 perpendicularly in the normal direction without causing refraction and reducing optical loss. In the present embodiment, the light guiding member 4 has a circular contour in a plan view. The top surface 42 has a planar region 421 and a curved surface region 422 located at the periphery of the planar region 421. The planar region 421 of the top surface 42 is parallel and equal in size to the bottom surface 41. The side surface 43 has a sloped area 431 extending obliquely upward from the bottom surface 41, and an outer annular surface 432 extending upward from the top edge of the inclined surface area 431 to extend the bottom edge of the curved surface area 422. The curved surface region 422, the inclined surface region 431, and the outer annular surface region 432 are all annular, and the outer annular surface region 432 surrounds the outer diameter D1 of the light guiding member 4. The bottom surface 41 of the light guiding member 4 covers the platform portion 12 and the circuit board 31, that is, the periphery of the platform portion 12 and the circuit board 31 does not exceed the range covered by the bottom surface 41 of the light guiding member 4, preferably, the light guiding member 4 The outer diameter D1 can be 1.1 to 5 times the outer diameter D2 of the platform portion 12, so that the light emitted by the light-emitting diode 32 can first enter the light guiding member 4 to make the light uniform. In the embodiment, the light guiding member 4 The outer diameter D1 is 50 mm, and the outer diameter D2 of the platform portion 12 is 35 mm. And the curved area 422 is used to increase the refractive angle of the light, and the inclined area 431 is used to destroy the total reflection, so that the light can be emitted by the inclined area 431. In terms of actual size, the curved surface region 422 may have a cone angle of 0.1 to 0.9 in a longitudinal section (as shown in FIG. 2), or may have a radius of curvature of 1 to 5 mm. The rounded corner, in this embodiment, has a cone angle of 0.4. The angle A of the chamfered portion of the beveled region 431 with respect to the plane of the bottom surface 41 may be between 20 and 60 degrees, and is 28.1 degrees in this embodiment. The thickness of the light guiding member 4 (the distance between the bottom surface 41 and the planar region 421 of the top surface 42) may be 5 to 20 mm, which is 8.5 mm in this embodiment.

因此,由發光模組3射出的光線經由導光件4的曲面凹穴44射入導光件4內,射到頂面42的平面區421的光線可直接射出(少數光線可能有全反射,但傳導至斜面區431時仍可射出),射到頂面42的曲面區422的光線會因曲面區422的曲率而增加光線的折射角度,部分光線可直接射出(此時出光角度會因曲面區422的曲率而增大)而部分射到斜面區431,並利用斜面區431破壞全反射,使光線可由斜面區431出光,並配合燈座1的平台部12提高發光模組3以高於基部11的頂側111及透光燈罩2的結合部22,使由斜面區431射出的光線能夠射出透光燈罩2,而能提高發光二極體燈具整體的出光角度,參閱圖3,本實施例的出光角度較佳能達到160度(如圖3中曲線C1所示),相較於現有發光二極體燈泡僅能發出的120度(如圖3中曲線C2所示),明顯提供了較寬廣的出光角度而接近於白熾燈之出光角度。Therefore, the light emitted by the light-emitting module 3 is incident into the light guide 4 through the curved recess 44 of the light guide 4, and the light that hits the flat area 421 of the top surface 42 can be directly emitted (a small amount of light may have total reflection, but When the conduction to the bevel area 431 is still possible, the light hitting the curved surface area 422 of the top surface 42 increases the refraction angle of the light due to the curvature of the curved surface area 422, and some of the light can be directly emitted (the light exit angle is due to the curved surface area 422). The curvature is increased and partially incident on the slope area 431, and the total reflection is broken by the slope area 431, so that the light can be emitted by the slope area 431, and the light-emitting module 3 is raised above the base 11 in cooperation with the platform portion 12 of the socket 1. The combination of the top side 111 and the light-transmitting cover 2 allows the light emitted from the sloped area 431 to be emitted from the light-transmitting cover 2, thereby improving the light-emitting angle of the entire light-emitting diode lamp. Referring to FIG. 3, the embodiment of the present invention The light exit angle is preferably up to 160 degrees (as shown by curve C1 in Fig. 3), which is only 120 degrees higher than that of the existing light-emitting diode bulb (as shown by curve C2 in Fig. 3), which obviously provides a wider range. The light exit angle is close to the light exit angle of the incandescent lamp.
