In this paper, we design a single concentrator to homogenize and concentrate the solar energy. The proposed concentrator only consisted of an array of refraction prisms. In order to homogenize the irradiance, all pitches of the Fresnel concentrator focus on the different position of the receiver. Finally, the Fresnel lens that achieves the uniformity of U is 14.6. An acceptance angle of 0.305 degrees is achieved without using additional secondary optics. Full Width at Half Maximum (FWHM) of illumination distribution is 1.4 mm. (C) 2011 Elsevier B.V.

A cost effective, high throughput, and high yield method for street lamp was proposed in this paper. We integrated the imprinting technology and the reflective optical element to improve the conventional street lamp. The novel design has 40% enhancement in illumination intensity, the uniform illumination and the glare effect elimination.
