Abstract: Disclosed are a color converting element and a method for manufacturing the color converting element. The disclosed color converting element includes: first wavelength conversion cells spaced apart from one another; and second wavelength conversion cells arranged among the first wavelength conversion cells. The first and second wavelength conversion cells are made of a material containing glass. The color converting element of the disclosed technology is configured in that color converting cells having different color converting characteristics are periodically arranged, when the color converting element is applied to a color converting glass material which may improve thermal and chemical durability of white LEDs, thus minimizing the degradation of efficiency or luminance caused by an interaction between color converting phosphors or active ions and allowing for ease of adjustment of color rendering index.

Abstract: A light combined with a cable illuminates a cable-stayed bridge in which a deck slab is fixed by a cable, or a structure in which wires or cables are combined, so as to achieve improved visual landscaping effects. The light of the present invention comprises a frame (110), a lamp (120), a housing (130), and a switch (150). The frame (110) comprises: a through-hole (111) for the a cable (13) to pass therethrough; a plurality of lamp mounting grooves (112) formed along the circumference of the through-hole (111); and fastening holes (114) which are formed along the circumferential surface of the frame and communicate with the through-hole (111) in the horizontal direction, and each of which has an inner surface provided with a female screw thread. The lamp mounting grooves (112) are formed into steps such that lamp mounting grooves closer to the through-hole (111) are deeper than those farther away from the through-hole.

Abstract: A shock-absorbing device for passenger conveyors comprises shock-absorbing members, which are attached respectively to at least one side of each of an inner rail and an outer rail of a track and protrude from the inner and outer rails toward a step roller. Supporting members are attached to the shock-absorbing members for supporting the shock-absorbing members together with the inner rail and the outer rail.

Abstract: Provided is related to a redundancy IO fuse circuit of a semiconductor device. The redundancy IO fuse circuit is advantageous to enhancing an overall processing speed of a redundancy operation by preventing a voltage drop by a threshold voltage due to an NMOS transistor, by reducing back bias effects, preventing a decrease of noise margins at an inverter connected to an IO bus, and by improving time delay property involved in current reduction according to variation of operation mode.
