Abstract

In the umbrella-type balloon-type lighting device, the operation for inflating the balloon is easy and does not impose a large burden on the operator. The lighting device has: a telescopic bone structure formed by arranging a plurality of flexible elongated stick parts (13) radially between the tip part (11) and the base part (12); Balloon part (31) outside the bone structure. The top part (11) and the base part (12) are connected to each other by telescopic telescopic struts composed of pipe parts (14) and rod parts (15). A locking member (44) that engages with the opening end to prevent the telescopic strut from moving in the direction of extension is provided at a position where the pipe member (14) penetrates downward and protrudes from the opening end thereof.

Description

technical field [0001] The present invention relates to a lighting device used at a construction site, an accident site, or an outdoor competition venue, and particularly relates to a so-called balloon-type lighting device. Background technique [0002] Conventionally, as a balloon-type lighting device, a gas-type device in which air is blown into a balloon by a blower or a fan to inflate it has been used. However, this type of device would not be usable in the event of a balloon rupture. In addition, since the blower or the fan must be constantly operated, it cannot be used in a place where the sound of its operation becomes disturbing, for example, during filming or the like. [0003] In response to this, various umbrella-type lighting devices have been proposed, in which a balloon is inflated by expanding a long and thin stick member such as an umbrella rib. For example, in the balloon-type lighting device disclosed in Patent Document 1, a plurality of bone members comp...
