Description
本創作係關於一種光學裝置，特別是有關於一種非對稱蝠翼型配光曲線透鏡及具有該透鏡的燈具。 The present invention relates to an optical device, and more particularly to an asymmetric batwing type light distribution curve lens and a luminaire having the same.
目前，發光二極體(light-emitted diode,LED)燈具的技術朝向快速發展的階段，已經有逐漸取代傳統燈具的態勢。LED燈具與燈管類型的燈具最主要的差異在於，LED燈具所採用的LED光源，係為LED晶粒所發出，其為點光源的效果。由於LED的點光源特性，在LED燈具的設計上，如何將光源反射，以使得此一點光源可發散成為均勻的光線，成為LED燈具的設計重點之一。 At present, the technology of light-emitted diode (LED) lamps is facing a stage of rapid development, and has gradually replaced the situation of traditional lamps. The main difference between LED lamps and lamp type lamps is that the LED light source used in LED lamps is emitted by LED chips, which is the effect of point light source. Due to the point light source characteristics of the LED, how to reflect the light source in the design of the LED lamp, so that the light source can be diverged into uniform light, which becomes one of the design priorities of the LED lamp.
傳統的燈具係呈圓形發光照明區域之分布，並且照明區域位於燈具正下方的區域形成中間偏亮的不均勻狀態，導致光線無法入射至特定的照射區域，例如在桌面的檯燈，當檯燈設置於桌面的前方或是後方時，其照明區域並非位於前方與後方之間的桌面上，而無法便於坐在後方的讀者可在具有均勻的光線分布的桌面上進行閱讀，即，照射光線無法完全在桌面的範圍之內。再者，例如是路燈照明，其路燈不易由道路旁兩側朝向路面形成均勻照射，即，照射光線無法完全在路面的範圍之內。因此，需要發展一種新式的光學裝置，以解決上述光線不均勻分布的問題。 The traditional luminaires are distributed in a circular illuminating area, and the area of the illuminating area directly under the luminaire forms an uneven central state, which causes light to be intruded into a specific illuminating area, such as a table lamp on a tabletop, when the desk lamp is set. When it is in front of or behind the desktop, the illumination area is not on the table between the front and the back, and it is not convenient for the reader sitting behind to read on the desktop with uniform light distribution, that is, the illumination cannot be completely Within the scope of the desktop. Furthermore, for example, street lighting, the street lamp is not easily uniformly illuminated by the sides of the road toward the road surface, that is, the illumination light cannot be completely within the range of the road surface. Therefore, there is a need to develop a new type of optical device to solve the above problem of uneven distribution of light.

The luminaire 500 includes an asymmetric batwing type light distribution curve lens 100, a light source 200, and a hood 300. The asymmetric batwing type light distribution curve lens 100 includes a substrate 102, a body 104, a first stopper 106, and a second stopper 108. The body 104 is disposed on the substrate 102, and a concave space 112 is formed from the bottom portion 110 of the body 104. The concave space 112 defines a light incident surface 114 for a light L1, L2, L3 to enter through the concave space 112. The light incident surface 114, the outer surface of the body 104 forms a first light exiting surface 116a, and the incident light rays L1, L2, L3 exit the first light exiting surface 116a via the body 104. The first blocking member 106 is disposed on the substrate 102. The first blocking member 106 abuts a side surface 118a of the body 104. The first light emitting surface 116a abuts the first blocking member 106 on the side surface 118a of the body 104. The first sidewalls 120 form a reflecting surface 122. The reflecting surface 122 abuts the light incident surface 114 to reflect the incident light rays L4, L5, L6 to the first light emitting surface 116a. The second blocking body 108 is disposed on the base material 102, and the second blocking body 108 abuts the other side of the body 104 and is opposite to the first blocking body 106, wherein the first light emitting surface 116a is in the body 104 One side abuts the second side wall 124 of the second block 108. The light source 200 is disposed in the asymmetric batwing type light distribution curve lens 100, for example, disposed in the concave space 112. The light source 200 is used to provide the light. The light source 200 is, for example, a light-emitted diode (LED). The hood 300 surrounds the periphery of the asymmetric batwing type light distribution curve lens 100.
參考第6圖，其繪示依據本創作實施例中燈具均勻投射於桌面之示意圖。本創作的燈具透過非對稱蝠翼光形，例是應用於檯燈之燈具，將正後方的光收斂在所需要照明的桌面，再使光投射在面上呈現出矩形照明區域R，可使投射面整體達到均勻性，輝度與照度一致性，並且具有防 止直接眩光的功能，可提升閱讀與使用品質。 Referring to FIG. 6, a schematic diagram of a lamp uniformly projected on a table top according to the present embodiment is shown. The luminaire of the present invention passes through the asymmetric batwing light shape, for example, the luminaire used for the desk lamp, converges the light directly behind the tabletop to be illuminated, and then projects the light onto the surface to present a rectangular illumination area R, which can be projected. Uniformity of the surface as a whole, uniformity of luminance and illumination, and protection The function of direct glare can improve the quality of reading and use.
綜上所述，本創作之非對稱蝠翼型配光曲線透鏡及具有該非對稱蝠翼型配光曲線透鏡的燈具，藉由設置於非對稱蝠翼型配光曲線透鏡一側面的第一擋體，使入射光線投射於預定區域，例如形成矩形區域，並且使入射光線均勻分布。 In summary, the asymmetric batwing light distribution curve lens of the present invention and the luminaire having the asymmetric batwing light distribution curve lens are provided in the first block of one side of the asymmetric batwing type light distribution curve lens. The body projects the incident ray into a predetermined area, for example, forms a rectangular area, and uniformly distributes incident light.
