Description

Embodiments of the present invention relate to lighting devices. Conventionally, in circular lighting fixtures, a circular light source for both normal and emergency use is positioned in the center of the fixture body. Power supplies, emergency units, and batteries are arranged around it, along with monitor lamps that display the battery charge status and light source status. These components are covered by a globe attached to the fixture body. In such lighting systems, the light from the monitor lamp may be difficult to see when the light source is constantly on. Japanese Patent Publication No. 2019-102369 This is a perspective view of a lighting device showing the first embodiment.This is a disassembled perspective view of the same lighting device.This is a bottom view of the same lighting device with the globe and light source cover removed.This is a perspective view of the same lighting device with the globe and light source cover removed.This is a bottom view of the fixture body of the same lighting device.This is a magnified perspective view of a portion of the fixture body of the same lighting device.This is a bottom view of the lighting device with the globe and light source cover removed, showing a second embodiment. The first embodiment will be described below with reference to Figures 1 to 6. Figures 1 and 2 show the lighting device 10. The lighting device 10 is a round bracket-type emergency lighting fixture. The lighting device 10 is installed on the ceiling or wall surface. The lighting device 10 comprises a housing 11, a light source unit 12, a terminal block 13, a power supply unit 14, an emergency unit 15, and a battery 16, all of which are arranged within the housing 11. The housing 11 comprises a device body 20 installed on the mounting surface and a globe 21 that is detachably attached to the device body 20. As shown in Figures 2 to 6, the device body 20 has a circular mounting surface 22 and a circumferential surface 23 that rises from the periphery of the mounting surface 22, and is formed in a cylindrical shape with the opposite side from the mounting surface 22 open. The mounting surface 22 has a wiring hole 24 in the center for inserting a power line, and a pair of mounting holes 25 and a pair of mounting holes 26 are provided radially around this wiring hole 24. The pair of mounting holes 25 located on the inner diameter side are for screw fastening to the mounting surface, and the pair of mounting holes 26 located on the outer diameter side are for suspension bolt mounting. On the inner surface of the mounting surface 22, a pair of cylindrical mounting portions 27 protrude diagonally opposite each other, flanking the central wiring hole 24, for mounting the light source unit 12. Additionally, support portions 28 and 29 protrude in directions intersecting the direction connecting the pair of mounting portions 27, supporting the back side of the light source unit 12. On the inner surface of the mounting surface 22, a wall portion (projection) 30 protrudes in a direction intersecting the direction in which the mounting holes 25 and 26 are aligned, at a position midway between the central wiring hole 24 and the circumferential surface 23. The wall portion 30 is provided in a wide wall shape along the direction in which the mounting holes 25 and 26 are aligned. One support portion 28 is provided on one end of the wall portion 30 in the width direction. The wall portion 30 is provided with a lower projection height from the inner surface of the mounting surface 22 than the one support portion 28. The emergency unit 15 is arranged on the inner diameter side of the wall portion 30, and the battery 16 is arranged on the outer diameter side. The wall portion 30 has the function of supporting the emergency unit 15 and the function of positioning the battery 16. On the outer diameter side of the wall portion 30, a battery positioning portion 31 is provided to position the four sides around the battery 16. The wall portion 30 also serves as a battery positioning projection 31 to position one side of the battery 16. A threaded portion 32, which is a spiral-shaped female thread for attaching and detaching the globe 21 by rotating it in the circumferential direction, is formed on the inner circumferential surface of the circumferential portion 23. The globe 21 is made of, for example, a milky white globe with light-transmitting and light-diffusing properties. The globe 21 has a circular front portion 33 and a circumferential portion 34 that rises from the periphery of the front portion 33, forming a cylindrical shape with the opposite side from the front portion 33 open. An insertion portion 35 is formed on the circumferential portion 34 of the globe 21, which is inserted into the inside of the device body 20. A threaded portion 36, which is a spiral male thread that screws onto the threaded portion 32 of the device body 20, is formed around this insertion portion 35. A disc-shaped packing 37 is
