Abstract: An illumination system includes a first light source, a wavelength conversion device, a first light-splitting element, a light-filtering device, and a light-homogenizing element. The first light source provides a first light beam. The wavelength conversion device includes a single wavelength conversion material configured to convert the first light beam into a conversion light beam. The first light-splitting element is disposed on transmission paths of the first light beam and the conversion light beam. The light-filtering device is disposed on the transmission paths of the first light beam and the conversion light beam. The light-homogenizing element is disposed on the transmission paths of the first light beam and the conversion light beam. When the first light beam is transmitted to the light-homogenizing element, the first light beam is not incident on the wavelength conversion device. A projection apparatus including the illumination system is also provided.

Abstract: An illumination system includes an excitation light source module, a light splitting and combining module, a filter module, and a wavelength conversion module. The excitation light source module provides an excitation beam. The light splitting and combining module is disposed on a transmission path of the excitation beam. The excitation beam includes a first and a second excitation beam which are different from each other in polarization state or wavelength range. The filter module is disposed on the transmission path of the excitation beam. The filter module includes a light passing area configured to allow the excitation beam to pass there-through and a light filtering area. The wavelength conversion module is disposed on the transmission path of the excitation beam reflected by the light filtering area and configured to convert the reflected excitation beam into a conversion beam. A projection apparatus including the above illumination system is also provided.

Abstract: An apparatus for assembling cable to connector includes a jig holder and a cable jig. The jig holder has a basic board defining a mounting space capable of locating a connector in the front thereof. The cable jig located in the rear of the mounting space of the jig holder has an upper jig member and a lower jig member disposed beneath the upper jig member. One of the jig members protrudes to form first spaced-apart barriers. A first receiving passage is defined between each pair of adjacent first spaced-apart barriers. The other jig member defines second receiving passages for receiving the first spaced-apart barriers respectively. A second spaced-apart barrier is defined between every two adjacent second receiving passages to space the two adjacent second receiving passages apart. The second spaced-apart barriers are inserted in the first receiving passages respectively.

Abstract: A cable testing device of the present invention can test sheltering performance of a cable which has a central wire, a shelter wrapped around the central wire and an exterior cover wrapped around the shelter. One end of the central wire and two ends of the shelter are earthed. The cable testing device includes a network testing device and a metal tube. The network testing device has an input which is connected to the other end of the cable and an output. The metal tube incloses the cable to be tested, one end of the metal tube is connected to the output of the network testing device, the other end is earthed. As a result, an electromagnetic field is formed in the interior of metal tube, thereby, the sheltering performance of the shelter of the cable can be tested directly before the whole cable product being assembled.
