Abstract:
An ultraviolet (UV) light source is provided. The device uses a high-uniformity diode array. A lens unit of collimated illumination lenses is used. A light source of UV light-emitting diode (UVLED) array is formed and passes through the lens unit to uniformly distribute the light source and obtain a collimated light. The present invention comprises a light source of UVLED array; a collimated illumination lens unit; and a substrate. The construction is simple. The present invention can be applied in the lithography of a semiconductor. The lithography forms contact lines of widths not greater than 3 microns (μm); soft-contact lines of widths of 3˜30 μm; and short-spaced lines of widths of 30˜200 μm. The present invention avoids the mask from contact wear-out for multiple uses, and further reduces the replacement rate.

Abstract:
A system for online monitoring powder-based 3D printing processes and method thereof are disclosed. A uniform light source having a single wavelength provided by the system is irradiated onto the powder layer before and after applied with glue. Intensities of such reflected images are obtained and subtracted from each other in an image process procedure. A difference obtained through the subtraction is compared with an original 3D model in a computer. If any defect is found such as being larger than a threshold value, the powder-based 3D printing processes will be terminated. Therefore, the technical effects of online printing processes monitoring, time saving and printing resources saving will be achieved.
Abstract:
Disclosed are a method and system for eliminating yellow ring phenomenon occurring on the white light emitting diode (LED) based on a blue light chip exciting yellow phosphor powders and having a packaging surface enclosing thereon. Lightspot images are repeatedly acquired outside the white LED, and then each analyzed to see if the yellow ring still exists on a lightspot. If yes, a further atomization process is performed on the packaging surface of white LED, until the acquired and analyzed image shows no yellow ring exists. A lightspot-by-lightspot basis is used in the yellow ring elimination task. In the image analysis, a look up table may be provided in advanced or established at the same time simultaneously with the yellow ring elimination task. The atomization performed on the lightspot may also consider a width issue.
