A light tower is a piece of mobile equipment which has one or more high-intensity electric lamps and a mast. Almost always, the lights are attached to the mast, which is attached to a trailer, with a generator set to power the lamps. Normally the lamps are metal halide bulbs and the generator is powered by a diesel engine. However, battery-powered, solar-powered and hydrogen-powered sets are available; light towers with electrodeless lamps or LED 〔(【引用サイトリンク】title=The AL4L LED Light Tower System from TEREX )〕 lighting are also sold. Modular kits sold by Multiquip, Winco and Kubota permit separation of the generator set, trailer, lights and mast from each other. Another variation is an inflatable mast. Particularly when an inflatable mast is used, the lights may be placed close to the ground, with a reflector attached to the mast.〔(【引用サイトリンク】title=оЮРЕМР US7621650 - Light tower, light tower support, method for operating a light tower and a ... - Google оЮРЕМРШ )〕 When soft lighting is wanted, an inflatable "balloon" diffuser may be used. An inflatable mast may serve as a diffuser. Light towers are used for construction. Some purveyors promote their use for other activities where strong, temporary, outdoor illumination may be wanted, such as mining, motion picture production, demolition, emergency services, oil refining, sport or agricultural sectors. ==Gallery== File:USMC-080708-M-MLG-9028.jpg |construction of military base File:COAL_SHOVEL_BEING_WORKED_AT_NIGHT_OFF_ROUTE_9,_MOST_OF_THE_MACHINES_ARE_USED_SEVEN_DAYS_A_WEEK,_24_HOURS_A_DAY_-_NARA_-_554771.jpg|light tower (far left) at open-pit coal mine File:Vehicle_Assembly_Building_damage_from_Hurricane_Frances_night_view.jpg |repairs to building File:2010-03-09_-_Airport_Link_-_01.jpg| construction of highway tunnel File:Hoover_Dam_Bypass_Bridge_Construction_11.jpg| light towers (upper left) used in construction of bridge File:US_Navy_060531-N-4267W-045_Utilitiesman_2nd_Class_Daniel_Dellamonica_assigned_to_Naval_Mobile_Construction_Battalion_Seven_(NMCB-7)_uses_a_Dumpy_level_to_make_sure_the_wooden_forms_are_evenly_placed_before_the_placement_of_conc.jpg|construction of military base File:US_Navy_081103-N-7367K-011_Seabees_assigned_to_Naval_Mobile_Construction_Battalion_(NMCB)_1_build_at_night_at_forward_operating_base_zero.jpg|military training for construction File:WKA_Ingersheim_25012012.JPG|construction of wind turbine 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Light tower (equipment)」の詳細全文を読む スポンサード リンク
