面向篮球场的新型LED照明光源的设计与研究
|
Abstract:
在篮球运动日益发展的今天，对篮球场馆室内设施提出了更高的要求，此类视觉状态对整体比赛状态影响重大。为了满足如今篮球场馆照明效果日趋提高的要求，针对室内篮球场馆传统灯具光学结构粗放、照明效果差等问题，结合篮球场馆的实际情况提出了一种新型的应用于室内篮球场馆的LED光源。在借鉴LED面光源的基础上，利用新型的复合型聚光器，将LED发出的光线汇聚并掠射在出光面板上，在理论分析结构参数对于照明效果影响的前提下，借助Tracepro软件进行模拟研究，首先模拟聚光器和LED组成的光源模块在不同掠射角度下获得的光斑面积和均匀度，发现0？掠射角下获得较大的光斑面积和光斑均匀度，并以此为基础进行整灯设计并模拟研究，获得了一个均匀度92.17%的高均匀度LED光源。
With the development of basketball today, higher requirements are put forward for indoor facilities of basketball stadiums. This kind of visual state has a great impact on the overall state of the game. In order to meet the requirements of improving the lighting effect of basketball stadiums, aiming at the problems of extensive optical structure and poor lighting effect of traditional lamps in indoor basketball stadiums, a new LED light source applied in indoor basketball stadiums was proposed in combination with the actual situation of basketball stadiums. Based on the LED surface light source, a new type of composite concentrator is used to concentrate and sweep the light emitted from LED onto the light emitting panel. Under the premise of theoretical analysis of the influence of structural parameters on the lighting effect, the simulation study is carried out with the help of Tracepro software. Firstly, the area and uniformity of the spot obtained by the light source module composed of the concentrator and the LED at different grazing angles are simulated. It is found that a larger area and uniformity of the spot are obtained at 0？ grazing angle. Based on this, a high uniformity LED light source with 92.17% uniformity is designed and simulated.
