摘要： The present invention provides a backlight module and an optical component thereof. The optical component comprises a substrate, a fluorescent layer, and a microstructure. The substrate has a first surface and a second surface. The fluorescent layer is applied on the first surface of the substrate, and the microstructure is formed on the second surface of the substrate. The fluorescent layer and the microstructure are set on two side of the substrate, respectively, so that at least one incident beam is optically refracted or scattered by the microstructure to uniformly penetrate through the microstructure and the substrate. Thus, a blue backlight which penetrate through the fluorescent layer and a yellow backlight which is excited from the fluorescent layer are mixed for ensuring the backlight module to provide a white backlight with uniform brightness and high brilliance.

摘要： The present invention provides a LED package assembly and a backlight module. The LED package assembly provides three adjacent individual LED package structures separated from each other, for generating red light, green light and blue light, respectively, all of which are mixed with each other to form white light. The foregoing design can ensure that each color light can not be absorbed or scattered by other color fluorescent powders, so that it is advantageous to individually control each color, enhance the luminous efficiency of each color light and expand the color gamut of white light.

摘要： A digital image capture and processing system capable of illuminating the entire field of view (FOV) of the system using a linear LED-based illumination array. The system includes a housing having an imaging window with a refractive-type illumination-focusing lens component integrated therewithin. The area-type image formation and detection subsystem, also disposed in the housing, has image formation optics for projecting a field of view (FOV) through the imaging window and onto an area-type image detection array, for forming and detecting 2D digital images of an object in the FOV, during object illumination and imaging operations. The linear LED-based illumination array is disposed immediately behind the refractive-type illumination-focusing lens component, for producing a field of wide-area illumination illuminating substantially the entire FOV over the working distance of the system. During object illumination and imaging operations, the illumination reflects off an object within the FOV and is transmitted back through the imaging window and onto the area-type image detection array to form one or more 2D digital images of the object.

The system includes image formation optics for projecting a field of view (FOV) through said imaging window and upon an object within the FOV, and forming an image of the object on an area-type image detection array having a plurality of rows of image detection elements, and detecting 2D digital images of the object while object illumination and imaging operations. The system also includes an LED-based illumination subsystem, with a LED illumination array, for producing a field of narrow-band illumination within the FOV, and illuminating the object detected in the FOV, so that the illumination reflects off the object and is transmitted back through the light transmission aperture and onto the image detection array to form the 2D digital image of the object. During the periodic snap shot mode of the operation, the image detection array supports periodic image acquisition cycles, and during each image acquisition cycle, substantially all image detection elements in the image detection array are exposed simultaneously to the illumination. In the illustrative embodiment, each image acquisition cycle has a predetermined time duration followed by a decode-processing cycle having a time duration approximately equal to the duration of the image acquisition cycle so that at least ten (10) image frames can be acquired per second.

摘要： A method of illuminating objects using adaptively controlled mixing of spectral illumination energy to form and detect digital images of objects at a POS. The method comprises providing, at a POS environment, a digital image capture and processing system having a system housing with an imaging window, and an area-type illumination and imaging station disposed within said system housing, for projecting a coextensive area-type illumination and imaging field (i.e. zone) through said imaging window into a 3D imaging volume during object illumination and imaging operations. As the object is moved through the 3D imaging volume, its motion is automatically detected, and signals indicative of said detected object motion are generated. In response to the generated signals, a first field of visible illumination is produced from an array of visible LEDs, simultaneously with a second field of invisible illumination from a array of infrared (IR) LEDs. These first and second fields of illumination spatially overlap and intermix with each other to produce a composite wide-area illumination beam that is at least substantially coextensive with the FOV. During object illumination and imaging operations, the relative power ratio (VIS/IR) of these fields of visible illumination and invisible illumination is adaptively controlled as one or more digital images of the illuminated object are formed and detected, captured and buffered, and ultimately processed so as to read one or more 1D and/or 2D code symbols graphically represented in the digital images.
