Abstract: A light emitting module includes a reflector, a lens and a light source disposed in the reflector. The lens is disposed in front of the reflector to refract light forwards so that the illuminating area of the light emitting module is adjustable. The light emitting module is particularly suitable for head light of vehicles. The light emitting module has a high illuminating efficiency and prevent light from dazzling a driver's eyes.

Abstract: A multi-band broadband antenna with mal-position feed structure includes a signal line of high-frequency radiation path with a signal feed-in point, and a ground line of low-frequency radiation path with opposing ground feed-in point and top-loading portion. The design exhibits a mal-position feed structure so that a co-planar waveguide structure is formed in the multi-band broadband antenna to increase the antenna's operating bandwidth.

Abstract: The proposed antenna structure has first and second asymmetric radiated-strip structures developed by modifying the structure of a printed T-type monopole. Specifically, by combining the radiated-strip and the shorting-line, the proposed antenna structure is similar to modified Type III balun and dipole fed by microstrip-line structure. Hence, the proposed antenna structure can also be regarded as a “quasi-balanced” antenna structure.

Abstract: A lighting fixture includes a light source, a lamp case, a power supply device, a shaped reflector and a prism. The shaped reflector has inwardly curved front and back walls each consisting of multiple conical faces abutted against one another and sloping at different angles. The angle of inclination of one lower conical face is relatively closer toward the center of the shaped reflector than that of the adjacent upper conical face. Thus, the shaped reflector effectively and evenly reflects the light emitted by the light source onto a predetermined rectangular or particularly shaped illumination area. Therefore, the lighting fixture is practical for road illumination, lounge illumination, advertizing light box and streamline table light applications to effectively and evenly illuminate the desired area, saving much power consumption.
