  • Publication number: 20070001185
    Abstract: A LED backlight module including a diffusion plate, at least an optical devices, at least a light-emitting diode and a second reflection surface is provided. The optical device is provided underneath the diffusion plate and has a first reflection surface. The light-emitting diode is provided underneath the optical device, for emitting light to the first reflection surface where first reflection of the light is performed. The second reflection surface is provided underneath the light-emitting diode, for receiving the light of the first reflection and performing second reflection of the received light. By controlling light paths of LED with the optical devices, light emitted from LED may be leaded to a specific direction instead of directly emitting from a front surface of LED, so as to achieve the performance of color-mixing and uniform distribution.

  • Patent number: 7113690
    Abstract: An anti-counterfeit method and system by using a nano metal grating, wherein an object to be recognized is formed with the nano metal grating. During the recognition process, an incidental light is applied on the metal grating. In response to the incidental light, the metal grating has its specific optical incidence and reflection characteristics. The object is then identified whether it is genuine or fake by observing the refraction light passing through and reflection light reflected from the metal grating. Further, the incident light beam can be polarized to generate polarized light beams and then irradiated on the metal grating, whereafter the recognition of the object is performed by observing the reflection and refraction lights of the irradiated polarized light beam. The recognition further can be accomplished by rotating the metal grating, thus the intensity of the refraction and reflection lights will accordingly be changed, thereby identifying the object.

  • Patent number: 7023593
    Abstract: An apparatus for forming a nano grating device to film nano-scale interference fringes by holography in order to makes a nano-scale meshed structure is disclosed. A beam emitted form a light source passes subsequently through a beam splitter and two reflectors to reach at symmetrically mounted light emitting modules. The light emitting modules generate two beams passing along the same optical paths and then projecting on a photosensitive substrate that is attached on a hemi-sphere lens. Thus, a first set of interference fringes are formed. Then, the substrate rotates with an angle and then is subjected to exposure to form a second set of interference fringes crossing the first set of interference fringes. Thereby, a nano-scale meshed structure is obtained.

  • Patent number: 6919571
    Abstract: A micro fluorescent electrophoresis (EP) detection system for detecting fluorescent EP is disclosed. The size of the system is greatly minimized for carrying. The invention uses a laser diode with a cylindrical lens to perform light source detection. A probe is provided to receive excited light produced by the probed object and to convert it into an electronic signal for detection. This does not only lower the cost, but also largely reduce its size for the patient's convenience of carrying and self-testing.
