Description

Technical Field

[0001] The present invention relates to a light-emitting device provided with a power cord.

Background Art

[0002] As a switch for adjusting the luminous intensity of a light-emitting device, a multi-stage switch or a continuous switch is known. When illuminating at night in a shelter where a large number of people stay, it is often the case that a certain lighting with reduced luminous intensity is kept lit at all times. With a multi-stage switch, even when the luminous intensity is set to the lowest level, it may be too bright and interfere with sleep. Also, with a continuous switch, when using a lighting device at an outdoor construction site, due to vibrations during work or contact with the light-emitting device by workers passing by, the knob for continuous adjustment of the switch may move and the luminous intensity of the lighting may change. Problems to be Solved by the Invention

[0003] The present invention has been made in view of such circumstances, and an object thereof is to provide a floodlight device that can be quickly adjusted to an appropriate illumination luminous intensity corresponding to use in various places. Means for Solving the Problems

[0004] The light-emitting device of the present invention is a floodlight device including a light-emitting body and a power cord for supplying power to the light-emitting body, and is characterized in that an intermediate portion of the power cord near the light-emitting body is provided with a first adjustment unit for performing multi-stage adjustment of the luminous intensity when the light-emitting body is lit and a second adjustment unit for performing continuous adjustment of the luminous intensity when the light-emitting body is lit. Effects of the Invention

[0005] While observing the luminous intensity when the light-emitting body 10 is lit, it is possible to quickly perform adjustment of an appropriate luminous intensity in various places at an intermediate portion of the power cord near the light-emitting body.

Best Mode for Carrying Out the Invention

[0007] Hereinafter, the light-emitting device of the present invention will be described based on embodiments with reference to the drawings. FIG. 1 shows each component of the light-emitting device according to the embodiment of the present invention. The light emitter 10 is supported by a tripod 11 so that it can be folded and miniaturized. The light emitter 10 is also provided with a power cord 12 for connecting to a power source such as a storage battery. In the middle of the power cord 12 near the light emitter 10, there are provided a multi-step dimming unit (first adjustment unit) 13 for adjusting the luminous intensity of the light emitter 10 at the time of lighting in multiple steps, and a continuous dimming unit (second adjustment unit) 14 for adjusting the luminous intensity of the light emitter 10 at the time of lighting steplessly, that is, continuously. FIG. 2 shows an electrical circuit diagram of the multi-step dimming unit 13 and the continuous dimming unit 14. By switching the switch of the multi-step dimming unit 13, multi-step dimming can be performed. If this switch is switched to the continuous dimming unit side, adjustment by the continuous dimming unit 14 becomes possible. Thereby, even when the power source is arranged at a position away from the light emitter 10, it is possible to quickly perform appropriate adjustment of the luminous intensity at various locations while observing the luminous intensity of the light emitter 10 at the time of lighting.
