Freeform LED lens for uniform illumination.
Light flux from LED must be redistributed to meet the needs of lighting in most cases, a new method is proposed for its secondary optic design. Based on refractive equation and energy conservation, a set of first-order partial differential equations which represent the characters of LED source and desired illumination were presented. The freeform lens was constructed by solving these equations ...
متن کاملFreeform lens design for LED collimating illumination.
We present a simple freeform lens design method for an application to LED collimating illumination. The method is derived from a basic geometric-optics analysis and construction approach. By using this method, a highly collimating lens with LED chip size of 1.0 mm × 1.0 mm and optical simulation efficiency of 86.5% under a view angle of ± 5 deg is constructed. To verify the practical performanc...
متن کاملImage-like illumination with LED arrays: design.
An array of spatially distributed light-emitting diodes (LEDs) can produce an illumination pattern that approaches an image by individually modulating each LED. In this letter, I analyze the first-order design of such systems in order to achieve the best match between the illumination distribution and a desired image. In particular, simple formulas are given for the optimal number of LEDs, work...
متن کاملSecondary optical element design for intracorporeal LED illumination system.
In this Letter, we propose an intracorporeal illumination system for providing uniform and wide-field illumination during minimally invasive surgery. The illumination system is comprised of an Alexis wound retractor, a set of LEDs, and secondary optical elements (SOEs). The SOE was composed of a Fresnel lens and a total internal reflection lens, which was designed to improve the optical perform...
متن کاملA new method for oblique microscopical illumination.
THE purpose of the technique described in this paper is to provide the easiest possible means of controlling the direction and degree of obliquity of the light used to illuminate microscopical objects. The method is applicable when striations or other regularly-repeated markings on objects are situated so close together that, with axial illumination, the diffraction-spectrum they produce lies p...
