Interior light design system based on 3D laser holographic projection

针对当前室内光线系统抗干扰性能差、反应时间较长和运行能耗高的问题,设计了基于3D激光全息投影的室内光线系统。以3D激光全息投影单元作为主控单元,将光照强度采集单元、人体热释红外集取单元、窗帘控制单元、灯亮控制单元和3D激光全息投影相互连接,实现硬件部分的组建。软件部分设置为室内光线系统初始化后,对室内是否有人进行判断,并确定当前光照是否满足室内人员需求,根据实际情况通过灯光等级的调整和3D激光全息投影对室内光线的调整,完成室内光线的调节与控制。实验表明,该系统具有较强的抗干扰性,系统平均反应时长为0. 2 s,能耗平均值能够控制在70J左右。实验数据表明该系统运行时的稳定性较强,反应速度快,具有可实践性。

Aiming at the problems of poor anti-jamming performance such as long response time and high operation energy consumption of indoor light system,the indoor light system based on 3 D laser holographic projection is proposed and designed. The 3 D laser holographic projection unit is taken as the main control unit. The light intensity acquisition unit,the human pyroelectric infrared acquisition unit,the curtain control unit,the light-on control unit and the3 D laser holographic projection are connected with each other to realize the hardware part. After the initial installation of the system,the software part judges the exist of people and determines the current light needs. According to the actual situation,through the adjustment of light levels and 3 D laser holographic projection of indoor lighting adjustments to complete the indoor light regulation and control. Experiments show that the system has a strong anti-interference,the system average response time is 0.2 s,the average energy consumption can be controlled at around 70 J. Experimental data show that the stability of the system running is strong,with fast response and is practical.
