Title:
LIGHTING APPARATUS
Document Type and Number:
Japanese Patent JP2017157384
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compact lighting apparatus while reducing the number of bolts used in assembling the apparatus and reducing assembling man-hours.SOLUTION: As a pressure-resisting explosion-proof container (for accommodating battery) is composed of an apparatus body 2 and a fixed frame 3 by fastening the apparatus body 2, the fixed frame 3 and a front frame 4 in a state of being jointly fastened, and a pressure-resisting explosion-proof container (for accommodating LED) is composed of the fixed frame 3 and the front frame 4, bolts used in assembling two pressure-resisting explosion-proof containers can be shared. Thus the number of bolts used in assembling the pressure-resisting explosion-proof containers, and the assembling man-hours can be reduced, and the apparatus can be miniaturized. Further by releasing the fastening of only a first bolt 11 for joining, the fastening of the apparatus body 2 and the fixed frame 3 can be released (container for accommodating battery can be opened) while keeping a state of fastening the front frame 4 to the fixed frame 3 by a second bolt 12. Thus a replacement work of the battery can be performed without opening the container for accommodating LED.SELECTED DRAWING: Figure 9
