矩形复合抛物面空间双向照明节能多功能反光杯设计

Design of rectangular composite paraboloid three-dimensional two-way lighting and energy-saving reflective cup

  • 摘要: 提出了充分利用灯具空间,具有单体双向多功能的光学设计新理念。结合LED与CPC,根据光学扩展量守恒,借助光路可逆原理与边缘光线原理,构造矩形复合抛物面。根据我国最新的《读写作业台灯性能要求》GB/T 9473-2017,以出光口半宽、台灯辐照高度、截短后杯体长度比为3个因素,设计正交实验,确定台灯矩形复合抛物面最适合参数为:出光口半宽50 mm、最大进光半角47.73°、截取杯体长度36 mm。在照明方面,该矩形复合抛物面能够满足关于A、AA级的照度和照度均匀度要求;在弱光聚集方面,其太阳能芯片位置的照度是不经聚光情况的1.25倍;在聚光模式下,太阳能芯片的光伏转化效率是非聚光模式下的1.66倍。这是对当前市面上非聚光模式收集太阳能方式的补充。

     

    Abstract: A new concept of optical design with two-way multi-function for making full use of the lamp space was proposed.The rectangular composite paraboloid was constructed through combining the light emitting diode (LED) and the compound parabolic concentrator (CPC) based on the conservation of optical expansion and the principles of optical path reversibility and the edge ray.According to the latest performance requirements of reading and writing desk lamp in China, GB/T 9473-2017, the orthogonal experiment was designed based on three factors:the half width of light outlet, the irradiation height of desk lamp, and the length ratio of truncated cup body. It was determined that the most suitable rectangular compound parabolic parameters were as follows: the half width of light outlet of 50 mm, the max half angle of the inlet light of 47.73°, the truncated cup body length of 36 mm. Results show that in terms of illumination, the rectangular compound paraboloid satisfies the requirements for illumination and uniformity of national standard A and AA; in terms of low light collection, with the aid of the rectangular composite parabolic concentrator, the illumination of the solar chip position is 1.25 times higher than that without concentrator; in concentrating mode, the photovoltaic conversion efficiency of the solar chip is 1.66 times of that in non-concentrating mode. This is a complement to the current solar energy collection methods in the market, which are non-concentrated mode.
