技术领域technical field
本实用新型涉及景观照明灯具技术领域，更具体地说，涉及一种反射式防眩光LED洗墙灯。The utility model relates to the technical field of landscape lighting lamps, in particular to a reflective anti-glare LED wall washer.
背景技术Background technique
LED作为一种新型的绿色照明光源，由于其低碳、节能、环保等众多优势，越来越被社会各界所接受推广，洗墙灯作为一种景观亮化型的LED节能灯，多被应用于照亮建筑的墙面，勾勒出建筑轮廓，装饰河堤等，也可应用于广告牌的功能性照明，同时还可以做成护栏管灯，作为一种低位照明灯具。As a new type of green lighting source, LED is more and more accepted and promoted by all walks of life due to its many advantages such as low carbon, energy saving, and environmental protection. As a landscape lighting type LED energy-saving lamp, LED wall washer is mostly used It is used to illuminate the wall of the building, outline the outline of the building, decorate the embankment, etc. It can also be applied to the functional lighting of the billboard. At the same time, it can also be made into a guardrail tube light as a low-level lighting fixture.
洗墙灯的一个特点为灯具的主轴与被照明面基本平行，而大多数灯具的主轴与被照明面基本垂直。目前市场上的洗墙灯，通常采用对称配光的透镜或圆形反光杯作为光学器件，其光利用率理论上不超过50％，其实际利用率通常只有40％左右，导致光能大量损失；而透镜和反光杯的另一个主要问题是容易产生眩光。为了避免产生眩光，部分企业选择增加挡光板，但这样需要增加一个总部件，相应也会增加成本，而且会会影响外观。因此，如何解决洗墙灯的中心光强低和眩光问题，是本领域技术人员所面临的一大难题。One of the characteristics of the wall washer is that the main axis of the lamp is basically parallel to the illuminated surface, while the main axis of most lamps is basically perpendicular to the illuminated surface. At present, wall washers on the market usually use symmetrical light distribution lenses or circular reflectors as optical devices, and their light utilization rate does not exceed 50% in theory, and its actual utilization rate is usually only about 40%, resulting in a large loss of light energy. ; Another major problem with lenses and reflectors is that they are prone to glare. In order to avoid glare, some companies choose to add light baffles, but this requires adding a total part, which will increase the cost accordingly, and will affect the appearance. Therefore, how to solve the problem of low central light intensity and glare of the wall washer is a big problem faced by those skilled in the art.
根据检索，现有技术中已有相关的技术方案公开，如中国专利号：ZL201320110336.4，授权公告日：2013年7月17日，该申请案公开了一种反光杯配光的LED洗墙灯具光学结构，包括洗墙灯灯体，洗墙灯灯体包括底板和两个侧板，侧板分布于底板两侧，且侧板垂直于底板；所述洗墙灯灯体上方盖有出光玻璃；所述洗墙灯灯体内设有倾斜设置的铝基板，铝基板上设有LED；且所述洗墙灯灯体内还设有倾斜设置的反光杯。该方案增强了混光效果，但只在一个方向上能够将光线准直射出，中心光强低。According to the search, relevant technical solutions have been disclosed in the prior art, such as Chinese patent number: ZL201320110336.4, authorized announcement date: July 17, 2013, the application discloses an LED wall washer with reflective cup light distribution The optical structure of the lamp includes the lamp body of the wall washer. The lamp body of the wall washer includes a bottom plate and two side plates. The side plates are distributed on both sides of the bottom plate, and the side plates are perpendicular to the bottom plate; Glass; the lamp body of the wall washer is provided with an inclined aluminum substrate, and LEDs are arranged on the aluminum substrate; and the lamp body of the wall washer is also provided with an inclined reflective cup. This solution enhances the light mixing effect, but it can only collimate the light in one direction, and the central light intensity is low.
又如中国专利申请号：201180025418.2，申请日：2011年5月20日，该申请案公开了一种灯组件，包括线性发光阵列和反射表面，反射表面布置成用以限制直接光的角分布，同时用反射光补充被照亮的物体的平表面上的直接光的强度。反射表面可定形成用以引起在平表面的照亮部分上的总照明的分布均匀或线性地逐渐减小，或具有另一种所期望的曲线。反射表面可为散热反射器的一部分，散热反射器可包括安装表面、遮挡件、允许旋转调整的长方形安装孔、散热器安装孔和/或一个或多个出口孔，且可具有附接到其上的端件。该申请案难以有效汇聚光线，出光强度有待提高。Another example is the Chinese patent application number: 201180025418.2, application date: May 20, 2011, which discloses a lamp assembly, including a linear light emitting array and a reflective surface, the reflective surface is arranged to limit the angular distribution of direct light, Also supplements the intensity of direct light on flat surfaces of lit objects with reflected light. The reflective surface may be shaped to cause the distribution of the total illumination over the illuminated portion of the planar surface to be uniform or linearly tapered, or to have another desired curve. The reflective surface may be part of a heat dissipation reflector, which may include a mounting surface, a shield, a rectangular mounting hole allowing rotational adjustment, a heat sink mounting hole, and/or one or more exit holes, and may have on the end piece. In this application, it is difficult to effectively gather light, and the light intensity needs to be improved.

具体实施方式detailed description
为进一步了解本实用新型的内容，结合附图和实施例对本实用新型作详细描述。In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments.
实施例1Example 1
结合图1和图7，本实施例的一种反射式防眩光LED洗墙灯，主要由外壳1、出光板5、端盖6、LED光源3和反光杯4等组成，端盖设置在外壳1两端，LED光源3固定在光源板2上，光源板2和反光杯4固定在外壳1内，在外壳1顶部固定有出光板5，该出光板5为玻璃板，使光源板2和反光杯4被封装在外壳1内部。外壳1、端盖6和出光板5主要起到散热、支撑、保护的作用，防止外壳1内进水损坏电路元件。1 and 7, a reflective anti-glare LED wall washer of this embodiment is mainly composed of a housing 1, a light output plate 5, an end cover 6, an LED light source 3 and a reflective cup 4, etc., and the end cover is arranged on the housing 1 at both ends, the LED light source 3 is fixed on the light source board 2, the light source board 2 and the reflector cup 4 are fixed in the housing 1, and the light-emitting board 5 is fixed on the top of the housing 1, and the light-emitting board 5 is a glass plate, so that the light source board 2 and the The reflector 4 is packaged inside the shell 1 . The shell 1, the end cover 6 and the light-emitting plate 5 mainly play the roles of heat dissipation, support and protection, and prevent water from entering the shell 1 from damaging the circuit elements.
结合图1和图2，本实施例中的LED光源3的光轴x与反光杯4的中心轴y2垂直，LED洗墙灯的灯具光轴y1垂直外壳1底板，中心轴y2与灯具光轴y1平行。LED光源3位于光轴x与中心轴y2的交点O上，即把LED光源3设置在外壳1内部的侧壁上，且LED光源3位于中心轴y2上。本实施例中反光杯4内表面为反光弧面41，过中心轴y2的任一截面与反光弧面41的交线均为抛物线，使反光弧面41形成一个抛物面，众所周知，由抛物线焦点射出的光线经抛物面反射后都将准直射出，故使O点作为抛物线的焦点，如图5所示，则LED光源3投射到反光弧面41上的光线均被准直射出。此外，本实施例将LED光源3侧向设置，大部分光线经反光弧面41后准直射出，而不是直接出射，使更多的光线被平行汇聚，降低了眩光的产生，更有效的提高了洗墙灯的K值(灯具每千流明的中心光强值)，从而提高了洗墙灯的洗墙高度。1 and 2, the optical axis x of the LED light source 3 in this embodiment is perpendicular to the central axis y2 of the reflector 4, the optical axis y1 of the lamp of the LED wall washer is perpendicular to the bottom plate of the housing 1, and the central axis y2 is perpendicular to the optical axis of the lamp y1 parallel. The LED light source 3 is located at the intersection O of the optical axis x and the central axis y2, that is, the LED light source 3 is disposed on the inner side wall of the housing 1, and the LED light source 3 is located on the central axis y2. In this embodiment, the inner surface of the reflective cup 4 is a reflective arc surface 41, and the intersection line between any section passing through the central axis y2 and the reflective arc surface 41 is a parabola, so that the reflective arc surface 41 forms a paraboloid. All the rays of light will be collimated after being reflected by the parabola, so point O is used as the focus of the parabola, as shown in Figure 5, then the light projected by the LED light source 3 on the reflective arc surface 41 is collimated and emitted. In addition, in this embodiment, the LED light source 3 is arranged sideways, and most of the light is collimated and emitted directly after passing through the reflective arc surface 41, instead of being emitted directly, so that more light is converged in parallel, reducing the generation of glare, and more effectively improving The K value of the wall washer (the central light intensity value per thousand lumens of the lamp) is increased, thereby increasing the wall washer height of the wall washer.
为了优化设计，定义光轴x和中心轴y2所在面为中截面，使反光杯4关于中截面对称，则出光更均匀。在侧向设置LED光源3的情况下，将LED光源3下部全部设置成反光区域似乎能获得更强的亮度，但考虑到边缘区域的光线强度较弱，对洗墙灯的K值影响较小，而且多余的反光区会大大增加灯具的空间尺寸，故本实施例中反光杯4采用切除多余区域后的非完整抛物体结构。如图2、图3所示，反光弧面41的两侧边相平行，反光弧面41的顶边为顶部弧线412，该顶部弧线412所对应中心角为α，10°<α<170°，α越大，反光弧面41所围区域越大，所能汇聚光线越多，具体到本实施例中α为145°。In order to optimize the design, the plane where the optical axis x and the central axis y2 are located is defined as the middle section, and the reflector 4 is symmetrical about the middle section, so that the light output is more uniform. In the case of setting the LED light source 3 sideways, setting the lower part of the LED light source 3 as a reflective area seems to be able to obtain stronger brightness, but considering that the light intensity in the edge area is weak, it has little impact on the K value of the wall washer , and the redundant reflective area will greatly increase the space size of the lamp, so the reflective cup 4 in this embodiment adopts an incomplete paraboloid structure after cutting off the redundant area. As shown in Figure 2 and Figure 3, the two sides of the reflective arc surface 41 are parallel, the top edge of the reflective arc surface 41 is the top arc 412, and the central angle corresponding to the top arc 412 is α, 10°<α< 170°, the larger α is, the larger the area surrounded by the reflective arc surface 41 is, and the more light can be collected. Specifically, in this embodiment, α is 145°.
值得说明的是，在保证反射光线准直出射的前提下，LED光源3的直射光线是产生眩光的主要原因，因此要合理控制直射光线的截光角。结合图4，本实施例中顶部弧线412为出光边缘，使顶部弧线412上任一点到O点的线段与水平面夹角β在50～60°范围内，截光角变大，可有效控制眩光的产生，保证出光效果。It is worth noting that, on the premise of ensuring that the reflected light is collimated and outgoing, the direct light of the LED light source 3 is the main cause of glare, so the cut-off angle of the direct light should be reasonably controlled. 4, the top arc 412 in this embodiment is the edge of the light, so that the angle β between the line segment from any point on the top arc 412 to point O and the horizontal plane is in the range of 50-60°, and the cut-off angle becomes larger, which can effectively control The generation of glare ensures the light effect.
实施例2Example 2
本实施例的一种反射式防眩光LED洗墙灯，其基本机构与实施例1相同，其不同之处在于：本实施例中的中截面与反光弧面41的交线为中部弧线411，过中心轴y2的任一截面与反光弧面41的交线所在抛物线的开口均与中部弧线411所对应抛物线的开口相同，即反光弧面41为中部弧线411绕中心轴y2旋转所形成的抛物面。所选用β角为65°，α角为150°。本实施例中的反射光线分布更均匀，亮化效果更好。如图6所示的配光曲线图，曲线A为洗墙灯在剖面方向上的光型，角度约5度左右，略带偏光且偏向被照明面，曲线B为沿着洗墙灯照明方向上的光型，角度约30度左右。A reflective anti-glare LED wall washer of this embodiment has the same basic structure as that of Embodiment 1, the difference is that the intersection line of the middle section and the reflective arc surface 41 in this embodiment is the middle arc 411 The opening of the parabola where any section passing through the central axis y2 and the intersection line of the reflective arc 41 is the same as the opening of the parabola corresponding to the middle arc 411, that is, the reflective arc 41 is formed by the rotation of the middle arc 411 around the central axis y2. formed paraboloid. The selected β angle is 65°, and the α angle is 150°. In this embodiment, the distribution of reflected light is more uniform, and the lighting effect is better. As shown in the light distribution curve diagram in Figure 6, curve A is the light pattern of the wall washer in the cross-sectional direction, the angle is about 5 degrees, slightly polarized and biased towards the illuminated surface, and curve B is along the lighting direction of the wall washer The above light type, the angle is about 30 degrees.
以采用CREEXPE光源为例，采用普通透镜时其中心光强约15-20cd/lm，但如果采用本实施例中的反光杯4，在安装深度及β角相同时，其中心光强可提高到80-100cd/lm。因此在相同的灯具尺寸下可以有效提高灯具的K值，从而提高洗墙高度达到更优的亮化效果。Taking the CREEXPE light source as an example, the central light intensity is about 15-20cd/lm when a common lens is used, but if the reflector 4 in this embodiment is used, when the installation depth and β angle are the same, the central light intensity can be increased to 80-100cd/lm. Therefore, under the same lamp size, the K value of the lamp can be effectively increased, thereby increasing the height of the wall wash to achieve a better lighting effect.
实施例3Example 3

实施例4Example 4
本实施例的一种反射式防眩光LED洗墙灯，其基本机构与实施例2相同，其不同之处在于：本实施例中的α为80°，LED洗墙灯的灯具光轴y1垂直外壳1底板，所述中心轴y2与灯具光轴y1倾斜设置。该设置便于洗墙灯的安装，可调整洗墙灯的出光角度。A reflective anti-glare LED wall washer of this embodiment has the same basic mechanism as that of embodiment 2, the difference is that α in this embodiment is 80°, and the optical axis y1 of the LED wall washer is vertical The bottom plate of the casing 1, the central axis y2 is arranged obliquely to the optical axis y1 of the lamp. This setting is convenient for the installation of the wall washer, and the light output angle of the wall washer can be adjusted.
实施例5Example 5
结合图7，本实施例的一种反射式防眩光LED洗墙灯，其基本机构与实施例2相同，其不同之处在于：本实施例中β角为50°，α角为30°。所述外壳1内设置有13个LED光源3。根据照明范围选择LED光源3的个数，以获得适当的照明范围，优化洗墙效果，节省成本。Referring to Fig. 7, the basic mechanism of a reflective anti-glare LED wall washer of this embodiment is the same as that of Embodiment 2, the difference is that in this embodiment, the β angle is 50°, and the α angle is 30°. Thirteen LED light sources 3 are arranged in the housing 1 . The number of LED light sources 3 is selected according to the lighting range to obtain an appropriate lighting range, optimize the wall washing effect, and save costs.
