摘要： A light guide lens includes a lens body having a light incidence surface and a light emission surface, a plurality of refraction structures formed on the light incidence surface, and a plurality of reflection structures formed on the light emission surface. The refraction structures send incoming light rays to the light emission surface by refraction. Each of the refraction structures turns incoming light rays coming in all directions into refracted parallel light rays. The refracted parallel light rays arriving from the refraction structures reflect off the corresponding reflection structures and then laterally exit the lens body. The refracted parallel light rays arriving from each of the refraction structures travel to a corresponding one of the reflection structures, such that eventually the incoming light rays exit laterally. The present invention further provides a light emitting diode package structure having the light guide lens.

摘要： A light guide plate is provided. The light guide plate has a transparent substrate having a first optical face and a second optical face, a first micro structure and a second micro structure respectively corresponding to the first optical face and the second optical face. The first micro structure has a tunable composite optical effect with light collection and diffusion functions so as to increase brightness and evenness of exit light. The second micro structure has a design of curved face to destroy total reflection of light, such that bright lines can be effectively prevented from occurrence by avoiding the light outputting from the direction over against the first optical face. A back light unit having the light guide plate is further provided in the present invention.

摘要： An apparatus for homogeneously distributing lights includes a light guide plate, an incidence microstructure and an emergence microstructure. The incidence microstructure is arranged on a surface of the light guide plate and opposite to a light source. The emergence microstructure is arranged on a surface of the light guide plate opposite to the incidence microstructure. The lights emitted by the light source pass through said apparatus thereby being homogenously distributed. Thus the manufacture costs are lowered, and the light source utilization ratio is increased.

摘要： The present invention discloses a dual-lens hybrid diffractive/refractive imaging system comprising: a first lens including a concave surface and a convex surface; and the second lens including a convex surface and a concave surface. The concave surface of the first lens is an objective surface facing the object. The convex surface faces the convex surface of the second lens, while the concave surface of the second lens faces the charge-coupled device (CCD) through a filter. Any surface of the first lens and the second lens is spheric or aspheric. Moreover, the imaging system comprises at least one diffractive surface, referred to as a hybrid diffractive/refractive surface, formed on any surface of the two lenses. Therefore, aberration is eliminated and image quality is improved without increasing the number of lenses.
