【摘要】：设计了一种防眩光LED工矿灯,在工矿灯中加入漏斗形自由曲面反光件,优化工件外表面的形状使灯杯内壁照度变均匀,大大降低工矿灯的眩光值。通过Solid Works建模、TracePro模拟计算分析,优化后的眩光值由52.8降为24,能够满足各类体育照明的要求。从人眼视觉角度分析设计结果,优化前人眼直接看到极亮的LED芯片且灯杯内壁均匀度只有0.383,优化后人眼看不到LED芯片只能看到灯杯内壁,其照度均匀度达0.824,平均照度值也大大降低,人眼可以直视灯具而不刺眼。与现有灯具比较,防眩光优势突出,市场前景广阔。
[Abstract]:A glare proof LED lamp is designed. A funnel-shaped free-form surface reflector is added to the lamp lamp. The shape of the outer surface of the workpiece is optimized to make the illumination of the inner wall of the lamp cup uniform. The glare value of mine lamp was greatly reduced. The optimized glare value was reduced from 52.8 to 24 by Solid Works modeling and TracePro simulation analysis. Can meet the requirements of various sports lighting. From the point of view of human visual analysis of the design results, optimize the previous human eyes directly see the extremely bright LED chip and lamp cup wall uniformity is only 0.383. After optimization, the LED chip can only see the inner wall of the lamp cup, its illumination uniformity is 0.824, the average illumination value is also greatly reduced, the human eye can directly look at the lamp without dazzling. Compared with the existing lamps. The glare-proof superiority is outstanding, the market prospect is broad.
