  • Publication number: 20090279053
    Abstract: A method for continuously projecting images by enabling an apparatus including a light source, an image creation unit, and a projection unit includes receiving video signals from a predetermined source; creating a plurality of images from the video signals while being impinged by light emitted by the light source; receiving the images from the image creation unit; and activating the projection unit to project the images on a projection screen in a predetermined rapid succession so as to create a motion picture effect. As such, lighting adjustment and natural beauty simulations in a vivid way can be achieved.

  • Publication number: 20090275257
    Abstract: An LED chip encapsulation process includes the steps of (a) forming a fluorescent member by injection molding to encapsulate an LED chip; (b) hardening the fluorescent member; (c) forming a transparent dome to embed and encapsulate the LED chip and the fluorescent member; and (d) securing the dome and the substrate together to finish a packaging of the LED chip. Shape of the fluorescent member disposed on the LED chip can be controlled precisely, thereby increasing quality and color uniformity of the produced LED chip. Alternatively, the LED chip is a remote LED chip and step (a) is replaced by forming a plastic member to encapsulate the LED chip and forming a fluorescent member on the top of the plastic member by injection molding.

  • Publication number: 20090273289
    Abstract: A lamp unit includes a power cord having a mating plug at one end and a corresponding mating plug at the other end, a bulb seat, an LED holder, an LED, and a housing. The LED is mounted on the LED holder in a watertight fashion and the LED holder is mounted on the bulb seat in a watertight fashion so as to prevent water from getting in the bulb seat. The LED can be replaced with another LED capable of emitting light of different color. The housing can be replaced with another housing of different shape. The corresponding mating plug of one lamp unit is adapted to connect to the mating plug of another lamp unit so as to form an LED light string for decoration of any desired length. The invention is highly adaptable to be employed in different environments and events.

  • Publication number: 20090272990
    Abstract: A light mixing apparatus of a light emitting diode (LED) is installed on a light emitting surface of the LED. The light emitted from the LED is mixed by a light mixing module of the light mixing apparatus uniformly for adjusting the light output angle. After the angle increases, the light is scattered into a fixed base of the light mixing apparatus, reflected to a containing groove of the light mixing apparatus by a reflecting layer of the fixed base, and guided into the total internal reflection lens of the containing groove. After the total internal reflection lens gathers the light, the light is projected onto a projected surface. If the LED is made of a multi-chip package, the light mixing apparatus can be used for improving the luminance of a light emitted by the LED onto the projected surface and the uniform distribution of the luminance.

  • Publication number: 20090214126
    Abstract: A gray code encoding and decoding method applied to holographic storage devices is proposed. The encoding method uses gray levels of a 2D detector to encode a certain amount of original bits of the original data, and then sends them to a spatial light modulator (SLM) for encryption. The decoding method corrects the received gray levels to the original gray levels, and then compares the maximum gray level with the original gray levels to decode the original gray level into binary data. The proposed encoding and decoding method can better make use of storage locations of the 2D detector and get a code rate close to 1.

  • Publication number: 20090167788
    Abstract: A method of increasing color gamut of a color display includes grouping subpixels of R, G, and B primary colors of a pixel by grouping R, G, and B light sources of the color display with a corresponding light intensity adjustment mechanism based on an overlapping degree between two response spectrums of the light sources such that response spectrums of the light intensity adjustment mechanism of the same group have a least overlapping with that of other groups; and enabling groups of R, G, and B subpixels, activating R, G, and B light source and the corresponding light intensity adjustment mechanism, and disabling the remaining groups of subpixels all by turns for creating a vivid complete picture by time division color-mixing

  • Patent number: 7486354
    Abstract: A cut filter is used in a backlight module or a display device and positioned over the light source to filter off a part of the light comprising an overlap of at least two of the red light, the green light, and the blue light. By filtering off the overlapping part of light emitted from the light source to obtain a purer primary color light, the display device equipped with a conventional color filter can attain an improved color gamut.

  • Publication number: 20090025427
    Abstract: A manufacturing method for micro components includes the steps of manufacturing a large component by molding and shaping a thermally contractible material; heating and cooling the large component, such that the size of the large component can be reduced by the contraction of the material to form a reduced component; duplicating the reduced component to obtain a mold; and manufacturing a further reduced component by the molding and shaping process of the mold. The manufacturing method simply requires the processes of duplicating the component, contracting the material with an equal contraction ratio, and preparing the mold, and thus the manufacturing method is simple, easy and fast. The method can overcome the shortcomings of the prior art, of which the precision and the freedom for the external design of the micro components cannot be controlled easily.

  • Publication number: 20090015157
    Abstract: A phosphor package of light emitting diodes includes a lens made of a transparent optical material, and a side of the lens with at least one phosphor containing groove corresponding to a light emitting diode chip. The concentration of the phosphor is adjusted before a required quantity of phosphor is adhered into the phosphor containing groove. The phosphor is baked and solidified. A gel is filled into the gap between the wire-bonded light emitting chip and the phosphor for binding with each other to complete the manufacturing process of a phosphor package; and such manufacturing process can effectively and accurately control the phosphor to achieve high quality stability and color uniformity.

  • Publication number: 20080258040
    Abstract: A direct-light-type backlight module uses optical feedback to control point light sources for obtaining a default luminance. Each point light source drives a section in a cyclic time domain to em it a light. A photo detector detects a brightness and the brightness is thus control led by the optical feedback from the photo detector.
