一种驱蚊灯的光电性能研究

Study on Photoelectric Performance of a Mosquito-repelling Lamps with LED Light Source

对某一型号LED柔性灯丝灯制成的驱蚊灯进行部分光学性能研究,分析在不同输入电压驱动驱蚊灯的情况下,在稳态时表现出的光通量、光效、色温、电流等随输入电压的变化而产生的变化情况,以及不同电压下稳态变化情况的对比。根据实验数据,驱蚊灯的光通量、功率均随着输入电压的升高而逐渐升高,电压的升高导致光效的变化呈现先上升再逐渐下降的变化趋势,特别是在225~230 V这个区段,光效的下降速度最快,200~210 V光效增加了1.1%,从210~230 V下降了4.4%。驱蚊灯的光电性能受到输入电压的直接影响。

This experiment is to study the optical performance of mosquito repellent lamp made of a certain type of flexible LED filament lamp.The experimental variables are the changes of light flux,light efficiency,color temperature and current with the changes of input voltage when driving mosquito repellent lamp under different input voltage,and the comparison of steady-state changes with different voltage.According to the experimental data,the following conclusions can be drawn:the light flux and power of mosquito repellent lamp increase gradually with the increase of input voltage.The increase of voltage causes the change of light efficiency to increase first and then decrease gradually.Especially in the 225 V^230 V region,the decline rate of light efficiency reaches the fastest,which increases by 1.1%from 200 V to 210 V and decreases by 4.4%from 210 V to 230 V.The photoelectric performance of mosquito repellent lamp is directly affected by the input voltage.
