DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device used for outdoor night work or the like.

[0002]

2. Description of the Related Art When night work is performed on an outdoor construction site, a lighting device such as a floodlight using a power supply device such as an engine generator is used to illuminate the work site brightly.

[0003] In this case, in order to improve the ease of handling by integrating the power supply device and the projector, the power supply device is mounted on a wheeled trolley, and a telescopic support is provided on the trolley.
By attaching a halogen lamp or the like to the tip,
For example, as disclosed in Japanese Patent Application Laid-Open No. 8-138406, a mobile illumination device having mobility has been constructed. In this type of mobile lighting device, a relatively heavy power supply device is mounted, so the trolley is also sturdy and heavy, and the weight of the mounted power supply is added, so the center of gravity is relatively low and the stable posture is stable. Easy to be maintained.

[0004] Nevertheless, if the position of the lamp is increased by extending the support for mounting the lamp, the center of gravity is also increased. For example, Japanese Patent Application Laid-Open No. 11-7827 discloses a method for securing stability during operation. As described above, a stabilizer that can be expanded and contracted in the lateral direction of the cart is provided, and the height of each tip and the ground is adjusted to keep the cart horizontal and improve stability.

[0005]

In recent years, a relatively lightweight power supply device, for example, a hand-held portable power supply device has been widely used. When such a power supply device is used, it is required to reduce the weight of the bogie and the like to increase the mobility.

[0006] However, since the support columns need to have a certain height, the position of the center of gravity tends to be high. Therefore, some measure is required to maintain stability, especially when the support is used with the support extended. However, it is not preferable to provide a robust stabilizer as disclosed in the above-mentioned publication because the mobility is impaired.

[0007]
