A cost effective, high throughput, and high yield method for the increase of street lamp potency was proposed in this paper. We integrated the imprinting technology and the reflective optical element to obtain a street lamp with high illumination efficiency and without glare effect. The imprinting technique can increase the light extraction efficiency and modulate the intensity distribution in the chip level. The non-Lambertian light source was achieved by using imprinting technique. The compact reflective optical element was added to efficiently suppress the emitting light intensity with small emitting angle for the uniform of illumination intensity and excluded the light with high emitting angle for the prevention of glare. Compared to the conventional street lamp, the novel design has 40% enhancement in illumination intensity, the uniform illumination and the glare effect elimination.
本文提出了一种经济高效、高通量且高产量的提高路灯效能的方法。我们将压印技术与反射光学元件相结合，以获得具有高照明效率且无眩光效应的路灯。压印技术可以提高光提取效率并在芯片层面调节光强分布。通过使用压印技术实现了非朗伯光源。添加紧凑的反射光学元件以有效抑制小发射角的发射光强度，从而实现照明强度均匀，并排除大发射角的光以防止眩光。与传统路灯相比，这种新颖的设计在照明强度、均匀照明和消除眩光方面提高了40%。
