LED黑板灯的设计建议

Design Suggestions for LED Blackboard Lights

黑板照明是影响课堂教学质量的关键因素之一,黑板照明产品光学设计是保证黑板照明质量的先决条件。本文从LED特性比较、整灯参数计算方面给出了LED黑板灯的光源选型建议,阐述根据LED光源出厂bin区控制整灯混光后光色参数的方法。提出一种黑板灯具的配光设计及安装位置,实现黑板照度满足国家标准的同时,降低教师的不舒适眩光感受。

Blackboard lighting is one of the key factors affecting the quality of classroom teaching.The optical design of blackboard lighting products is a prerequisite to ensure the quality of blackboard lighting.In this paper,the light source selection suggestion of LED blackboard light is given from the aspects of LED characteristics comparison and calculation of the whole lamp parameters.The method of controlling the light color parameter of the whole lamp after mixing light is described according to the bin area of the LED light source factory.The light distribution design and installation position of a kind of blackboard light are proposed,which can reduce the uncomfortable glare feeling of teachers while meeting the requirements for illuminance in national standards.
