Abstract: A light-diffusing LED lens adopting an asymmetric free-form surface expression is provided to improve the uniformity ratio of illumination of the target region by controlling the light from the LED serving as a light source. The light-diffusing LED lens adopting an asymmetric free-form surface expression exhibits light control and illumination efficiency suitable for highway environment conditions and characteristics of traffic lanes. Both the light incident surface and the light emitting surface of the light-diffusing LED lens are formed into an aspherical surface, in which an asymmetrical free-form surface is optimally utilized to enable the free-form surface to be freely modified and changed by adjusting the coefficients of the aspherical surface or the like. The light-diffusing LED lens enables a numerical design and a mathematical design by means of the free-form surface, and enables a fine control to be performed by numerical control to thus improve accuracy of light control.

Abstract: An LED lighting source having a surface light source characteristic and an icicle type diffusion unit corresponding to the surface light source are integrally formed through coupling therebetween to provide a shield type structure having waterproof and dustproof functions. Also, the LED lighting engine may improve lighting efficiency and reduce manufacturing costs when compared to an existing lighting device, and may also be applied in various ways. Also, the LED lighting engine may satisfy quality and pricing standards for LED lighting which are the main variables visible to the eyes of a user. In addition, the LED lighting engine may be simply replaced with conventional LED lighting in a one-on-one ratio (size) which greatly influences market competitiveness. Also, the LED lighting engine may be simply and freely adjusted in terms of light uniformity and light diffusion angle.

Abstract: A reflector having a reflection pattern for compensating for a lighting characteristic of an LED package includes a body configured to be matched and coupled with the LED package having a discontinuous chip arrangement structure to improve the lighting characteristic of the LED package for divergent light. The body includes an inner wall having a diameter which is increased upwardly to form a narrow bottom and a wide top and including an opening formed at a lower end thereof so as to arrange the LED package therein. The inner wall of the body is formed with a trigonometric cross-wave pattern part which is patterned such that sine wave-type waves curved to form peaks and valleys are arranged to cross in a horizontal direction and a vertical direction at predetermined intervals over the whole area. The reflection pattern can compensates for an incomplete lighting characteristic of an LED package itself.
