LED读写作业台灯的设计建议

Design Suggestions of LED Table Lamps for Paper Task

照明质量不达标是导致近视的原因之一,本文对现行台灯性能标准GB/T 9473的光生物安全、遮光性、光度学、显色性等关键指标进行分析,提出光源选型及材料、电子、结构的设计建议。通过选择合理参数的光源,在台灯出光口增加有过滤蓝光功能的防护磨砂档板,添加使用时长智能提醒功能等措施,从而避免蓝光危害和用眼过度,达到保护视力的效果。

Substandard lighting quality is one of the causes of myopia.This paper conducts in-depth analysis and research on key indicators such as photobiological safety,shading,photometry and colour rendering in the performance standard GB/T 9473 of table lamps,and proposes suggestions about light source selection,materials,electronic and structural design of table lamps for paper task.By selecting a light source with reasonable parameters,adding a protective frosted baffle with a blue light filter function at the light outlet of the table lamp,and adding an intelligent reminder function for the duration of use,etc.,the blue light hazard and excessive use of eyes can be avoided,and the effect of protecting eyesight can be achieved.
