摘要： PROBLEM TO BE SOLVED: To provide a luminaire with high degree of safety by forming a protecting shield with a primary flying fragment preventing hole and concurrent serving as a vent hole for glass fragments of a lamp broken and scattered. SOLUTION: A luminaire has a mainbody 1 with at least one face open and a reflecting mirror 4 arranged facing to the opening face of the mainbody 1 to reflect light emitted from a lamp 5 to specified direction. In this case, a protecting shield 8 is mounted thereof for the lamp 5 broken during lighting. The protecting shield which has a primary flying fragment preventing hole and concurrently serving as a vent hole 10 to prevent the scattering of primary flying fragments 9 of the lamp 5 when broken is provided on the opening face of the mainbody 1.

摘要： PURPOSE:To enable a recessed luminaire reflector not fully installed to be easily recognized from any directions on a circumference by tilting a single-base type fluorescent lamp inside the reflector so that the end of the lamp is in a low position. CONSTITUTION:In a recessed luminaire, a single-base type fluorescent lamp 9 inside a reflector 1 is positioned with its end tilted relative to the transverse center so that when the reflector 1 is disconnected the space between the decorating frame 3 of a luminaire main body 2 and the reflector 1 can be detected easily from the floor face. Therefore, imperfect installation of the reflector 1 can be recognized easily from any directions around the luminaire and be corrected early.

摘要： PURPOSE:To minimize dead spaces and reduce the size by putting semiconductors with tab-terminals in a printed board, and treating (radiating) heat generated in the semiconductor with a sheet metal (case). CONSTITUTION:Semiconductors 2 having connections in the shape of fast-on tab terminals are put in a printed board 7. Consequently, it becomes possible to miniaturize a sheet metal (product). Besides, connection with the semiconductor 2 can be made not only with lead wires but also with solder, and it also becomes possible to widen the possibility of a connecting method. Furthermore, it is not necessary to use a special radiating board even for the radiation of heat generated by the semiconductor 2, and it is possible to radiate heat by using the wide area of the sheet metal (case) 3. Accordingly, it becomes unnecessary to consider the temperature rise of the semiconductor 2.

摘要： PROBLEM TO BE SOLVED: To provide a drain hole structure with no light leak, in which water and insects hardly enter. SOLUTION: A luminaire mainbody 9 has the bottom formed in a double structure with an upper side bottom plate 91 and a lower side bottom plate 92 vertically neighboring and opposing each other. Plural drain holes 31, 32 are formed in the upper side bottom plate 91 and the lower side bottom plate 92, respectively. Arrangement is made for the drain holes 31 in the upper side bottom plate 91 not to be vertically aligned with the drain holes 32 in the lower side bottom plate 92. A line connecting any drain hole 31 on the upper side to any drain hole 32 on the lower side is not vertical.

摘要： PROBLEM TO BE SOLVED: To prevent occurrence of the undesirable deformation of a packaged item for its protection by relaxing a state in which unbalanced pressure is applied onto a packaged item via a sleeve cushioning body through the agency of impact load pressure during dropping of the package or the like. SOLUTION: There is provided with a rectangular packaged item. Then, a rectangular packaging case 10 is provided to accommodate the packaged item. A plurality of sleeve-like cushioning bodies 20 are prepared to be interposed between each corner portion of the packaging case 10 and each corner of the packaged item. Each sleeve-like cushioning body 20 is a rectangular sleeve-like body including a pair of longitudinal surface portions 22 being parallel to the vertical surface of the packaging case 10 and a pair of lateral surface portions 24 at right angles with these portions. Slits 29 extending in the direction along the plate surface of the longitudinal surface portion 22 are formed at the end portions along each sleeve axis and positions over the lateral surface portions 24 in the sleeve-like cushioning body 20. These slits 29 serve to weaken strength at the end portions of the sleeve-like cushioning body 20.

摘要： PROBLEM TO BE SOLVED: To prevent break of a lighting device and insulation caused by water drops drained by forming a drain hole in a lighting fixture part having a glass globe fitting to a pole part and forming a drain guide for guiding water in the drain hole so that penetrated water does not come in contact with the lighting device. SOLUTION: A luminaire consists of a pole part 20 and a lighting fixture 10, and a lighting device is arranged in the lighting fixture 10. A glass globe 1 in the lighting fixture 10 is fit to the pole part 20. A drain hole 13 for draining water penetrated in the lighting fixture 10 is formed. A drain guide 19 for guiding water so that water does not come in contact with the whole or part of the lighting device is formed in the drain hole 13. The drain hole 13 is formed in the bottom of a lighting fixture holder 9. The drain guide 19 is connected to part of the periphery of the drain hole 13 and hangs down from there. The drain guide 19 limits the dropping direction of water drops 11 so as not to reach a power source terminal board 5 which is part of the lighting device and a power source wire. Thereby, the luminaire is made electrically safer.
