Description
本創作涉及LED照明技術，尤指涉及一種LED燈及其燈罩。The present invention relates to LED lighting technology, and more particularly to an LED lamp and a lampshade thereof.
現有的LED燈是由安裝在鋁材基板上的LED燈模塊、電源模組、PC(英文名為Polycarbonate，中文為聚碳酸酯)燈罩和堵頭構成。其中的燈罩是透明或半透明的塑料材質，並且兩面表面光滑，其存在有以下缺陷：其一，現有技術的PC燈罩兩面都是光滑的，無法對光線發生二次光學的作用，燈光通過PC燈罩時會形成直射光源，因此光線不柔和，不但會刺激眼睛，而且還容易使人產生疲憊的現象；其二，由於LED燈珠組照射在PC燈罩中間的光線較多，且現有技術的PC燈罩兩面都是光滑的，因而無法對光線產生二次光學的作用，所以PC燈罩的中間比較亮，兩側邊則比較暗，導致亮度不均勻。The existing LED lamp is composed of an LED lamp module mounted on an aluminum substrate, a power module, a PC (Polycarbonate in English, polycarbonate in Chinese), and a plug. The lampshade is made of transparent or translucent plastic material, and the surfaces on both sides are smooth, which has the following defects: First, the prior art PC lampshade is smooth on both sides, and cannot cause secondary optical effects on light, and the light passes through the PC. When the lampshade forms a direct light source, the light is not soft, which not only irritates the eyes, but also easily causes fatigue; secondly, because the LED lamp bead group illuminates more light in the middle of the PC lampshade, and the prior art PC Both sides of the lampshade are smooth, so they cannot produce secondary optics to the light. Therefore, the middle of the PC lampshade is brighter, and the sides are darker, resulting in uneven brightness.
有鑑於此，本創作之目的在於提供一種LED燈及其燈罩，可使光線柔和，並保持燈罩內之照度均勻。In view of this, the purpose of the present invention is to provide an LED lamp and a lampshade thereof, which can soften the light and maintain uniform illumination in the lampshade.
為解決以上技術問題，本創作提供的技術方案是：一種燈罩，包括透明或半透明之半弧形柱狀燈罩本體，該燈罩本體的內壁表面上設置光線反射結構。In order to solve the above technical problem, the technical solution provided by the present invention is: a lampshade comprising a transparent or translucent semi-arc cylindrical lampshade body, and a light reflecting structure is disposed on an inner wall surface of the lampshade body.

於較佳實施例中，該燈罩本體為PC(聚碳酸酯)燈罩本體。In a preferred embodiment, the lampshade body is a PC (polycarbonate) lampshade body.
在此基礎上，本創作提供一種LED燈，包括串並聯連接的LED燈珠組及電源模組，以及設置有如上述之燈罩。On this basis, the present invention provides an LED lamp comprising a LED lamp bead set and a power supply module connected in series and parallel, and a lamp cover provided as described above.
於較佳實施例中，該LED燈的燈管鋁蓋之橫截面積佔燈管橫截面積的三分之一，該燈罩的橫截面積佔燈管橫截面積的三分之二。In a preferred embodiment, the cross-sectional area of the aluminum cover of the LED lamp of the LED lamp accounts for one-third of the cross-sectional area of the lamp, and the cross-sectional area of the lamp cover accounts for two-thirds of the cross-sectional area of the lamp.
於較佳實施例中，該LED燈珠組安裝於一基板上。In a preferred embodiment, the LED bead set is mounted on a substrate.
與現有技術相比，本創作燈罩本體的內壁表面設置有光線反射結構，可使光線柔和，並保持燈罩內之照度均勻，具體而言，本創作包括但不僅限於以下優點：(1)本創作PC燈罩有二次光學的作用，燈光通過本創作PC燈罩會形成非直射光源，光線柔和，不會刺激眼睛，也不容易使人產生疲憊的現象；(2)PC燈罩亮度均勻，以改善PC燈罩的中間比較亮，而兩側邊比較暗的缺點。Compared with the prior art, the inner wall surface of the present lampshade body is provided with a light reflecting structure to soften the light and maintain uniform illumination within the lampshade. Specifically, the present invention includes but is not limited to the following advantages: (1) The creation of the PC lampshade has the function of secondary optics. The light will form a non-direct light source through the creation of the PC lampshade. The light is soft, it will not irritate the eyes, and it will not easily cause fatigue. (2) The brightness of the PC lampshade is uniform to improve The middle of the PC lampshade is brighter, and the sides are darker.
為了使本領域的技術人員更好地理解本創作的技術方案，下面結合圖式和具體實施例對本創作進一步的詳細說明。In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.
同時參閱第1及2圖，係表示本創作燈罩一較佳實施例的結構，該燈罩包括透明或半透明(優選為PC，中文為聚碳酸酯)之半弧形柱狀燈罩本體1，其開口處兩側分別向內延伸出橫折壁。該燈罩本體1長度L1為1172mm；外徑D為26.8mm；厚度Dr為0.8mm；開口處高度H1為21mm；寬度L2為16.8mm；開口處厚度H2為0.6mm。該燈罩本體1的內壁表面上設置有光線反射結構，具體是在燈罩本體1的內壁表面設置了多個大小一樣、間距一定的圓弧狀突起2，由此形成光線反射結構，最終產生二次光學作用。Referring also to Figures 1 and 2, there is shown a structure of a preferred embodiment of the present lampshade, the lampshade comprising a semi-arc cylindrical lampshade body 1 which is transparent or translucent (preferably PC, Chinese polycarbonate), A cross-shaped wall extends inwardly from both sides of the opening. The lampshade body 1 has a length L1 of 1172 mm; an outer diameter D of 26.8 mm; a thickness Dr of 0.8 mm; an opening height H1 of 21 mm; a width L2 of 16.8 mm; and an opening thickness H2 of 0.6 mm. The inner wall surface of the lampshade body 1 is provided with a light reflecting structure. Specifically, a plurality of arc-shaped protrusions 2 of the same size and a fixed pitch are disposed on the inner wall surface of the lampshade body 1, thereby forming a light reflecting structure, and finally generating Secondary optics.
請參閱第3圖，表示本創作的光路原理。當LED燈3光線照射在圓弧狀突起2上時，圓弧狀突起2會反射一定的光線，從而使PC燈罩本體1具有二次光學的作用，具體而言：一方面，燈光通過PC燈罩本體1時會形成非直射光源，光線柔和，不會刺激眼睛，且不容易使人產生疲憊的現象；另一方面，光線通過二次光學的作用，使光線均勻的通過PC燈罩本體1，因此PC燈罩的亮度均勻，改善PC燈罩的中間比較亮，而兩側邊則比較暗的缺點。Please refer to Figure 3 for the optical path principle of this creation. When the light of the LED lamp 3 is irradiated on the arc-shaped protrusion 2, the arc-shaped protrusion 2 reflects a certain light, so that the PC lamp body 1 has the function of secondary optics, specifically: on the one hand, the light passes through the PC lamp cover. When the body 1 is formed, a non-direct light source is formed, the light is soft, does not irritate the eyes, and is not easy to cause fatigue; on the other hand, the light passes through the secondary optics to make the light uniformly pass through the PC lamp cover body 1, thus The brightness of the PC lampshade is uniform, and the middle of the PC lampshade is brighter, while the sides are darker.
在此基礎上，本創作LED燈包括串並聯連接的LED燈珠組、電源模組以及上述燈罩，其中：LED燈珠組安裝於一基板上；LED燈的燈管鋁蓋之橫截面積佔燈管橫截面積的三分之一，燈罩的橫 截面積佔燈管橫截面積的三分之二，使得燈管的發光角度為270度。On the basis of this, the LED lamp of the present invention comprises an LED lamp bead group connected in series and parallel, a power module and the above lampshade, wherein: the LED lamp bead group is mounted on a substrate; the cross-sectional area of the aluminum lamp cover of the LED lamp is occupied. One-third of the cross-sectional area of the lamp, the cross-section of the lampshade The cross-sectional area accounts for two-thirds of the cross-sectional area of the tube, so that the angle of illumination of the tube is 270 degrees.
