摘要： PROBLEM TO BE SOLVED: To restrict the temperature rise of a lighting stand by providing a lamp guard cap having an inner space, which is communicated with a convection passage through an upper opening of a lamp guard, and having an air flow outlet opened downward. SOLUTION: A flow passage, in which the air flowed from an opening 13 of a base 2 flows so as to flow out from an air flow outlet 15 through a lower opening 12 of a bottom plate 10, an inner space of a lamp guard 7, an opening 11 of a top plate 9 and an inner space of a lamp guard cap 14, is formed. When a light source of a lighting stand 1 is turned on, a fluorescent lamp 6 generates the heat, and the air inside of the lamp guard 7 is heated, and an ascending air current is generated in the inner space of the lamp guard 7. Cold air of the outside is always sucked through the opening 13 of the base 2 by the force of the ascending air current, and the heated air is extruded outside from the air flow outlet 15 of the lamp guard cap 14. An airflow flowing around the fluorescent lamp 6 is generated by the ascending air current, and a luminaire such as a fluorescent lamp 6 is effectively cooled.

摘要： PROBLEM TO BE SOLVED: To prevent temporary wiring and receptacles from being exposed above the floor surface or below the ceiling by connecting wires at a wiring part buried in the concrete of floor, wall or column with a receptacle having a plug-in face exposed at the baseboard of wall or column. SOLUTION: Temporary electric wiring and receptacle 1 comprise a wiring part 2 buried under the floor surface, and a receptacle 4 having a plug-in face exposed at the baseboard of wall or column. Alternatively, temporary electric wiring and receptacle 20 comprise a wiring part 2 buried under the floor surface, a wiring part 2' taken out above the floor surface from a predetermined place, and a receptacle 4. According to these temporary electric wiring and receptacles 1, 20, cable of a motor drill 5, or the like, can be connected with a receptacle 4 ready to hand. These temporary electric wiring and receptacles 1 can be reused.

摘要： PROBLEM TO BE SOLVED: To project light to a ceiling and light up a specified floor surface at need by using a device such as a ball joint and an arm so as to incline a part of a luminaire. SOLUTION: This multifunction lighting stand has a ball joint 6 at the center in the height direction of a support 5 so that the lighting stand can be bent at a part of the ball joint 6. The bent support 5 is fixed at the angle of bend by a fixing screw 7. When an upper support 5b is inclined one side by the ball joint 6, a fluorescent lamp 8 of the upper support 5b obliquely projects the light upward and downward. Namely, the multifunction lighting stand 1 in this condition can light up the ceiling with the light obliquely projected upward, and it can light up a part of a floor surface with the light obliquely projected downward. With this lighting stand, construction of ceiling and construction of floor surface, which needs the fine accuracy, and a specified floor surface of an event place can be lighted bright.
