| 20110210368 | MICRO-COMPOSITE PATTERN LENS, AND METHOD FOR MANUFACTURING SAME - The present invention relates to a micro-composite pattern lens and to a method for manufacturing same. The micro-composite pattern lens of the present invention has a micro-composite pattern with one or more protrusions formed on one side of the lens having a predetermined curvature, and optical polymer nanoparticles arranged in the lens. The micro-composite pattern of the lens may form a wider angle of light emission, thus enabling an LED source, which is a point light source, to be converted into a surface light source having superior luminous intensity uniformity. The lens of the present invention is advantageous in that a single lens may serve as a light guide plate, a prism plate, and a diffusion plate, this eliminating the necessity of stacking optical plates, which might otherwise be required for conventional backlight units. According to the present invention, the angle of emission of the LED source which is approximately 90 degrees can be widened to 160 degrees or higher, and the local change in the micro-pattern and the mixture of ultrafine particles may improve the luminous intensity uniformity and the angle of emission of the light source. Also, wafer levels can be manufactured using a microfluidic channel array based on three dimensional molding techniques and the mixture of ultrafine particles. In addition, the use of single lens having a wider angle of light emission reduces the number of LEDs, thus reducing manufacturing costs and heat generated by LEDs. Further, the micro-composite pattern lens of the present invention has a double curvature structure to achieve improved luminous intensity uniformity and an improved angle of light emission as compared to a single curvature structure. | 09-01-2011 |
