AI Technical Summary

Technical Problem

Conventional lighting devices with integrated wireless communication antennas increase in thickness due to the arrangement of the wireless module board along the mounting direction, leading to a bulky lighting fixture.

Method used

The lighting device is designed with a light source board, a wireless module board, and a power supply board arranged to overlap, where the wireless module board and power supply board are positioned opposite to the light source board, and the antenna portion protrudes from the light source board through an insertion portion, allowing for wireless communication while reducing the overall thickness.

Benefits of technology

This configuration enables wireless communication capabilities with a reduced thickness, facilitating easier installation and reducing the size of the lighting fixture, thereby expanding installation possibilities.

Abstract

To provide a lighting device and a lighting fixture capable of radio communication and having a smaller thickness.SOLUTION: A lighting device (100) includes a light source substrate (130) on which a light source (115) is disposed, a wireless module substrate (140) on which an antenna unit (145) capable of wireless communication is provided, a power supply substrate (125) on which a power supply device that supplies power to the light source (115) is provided, and a fixing pin (30) for fixing the lighting device to an attachment object (50). The wireless module substrate (140) and the power supply substrate (125) are disposed so as to overlap the light source substrate (130) on a side opposite to a surface of the light source substrate (130) on which the light source (115) is disposed, an insertion portion (150) through which the antenna portion (145) is inserted is formed in the light source substrate (130), and the antenna portion (145) is disposed so as to protrude from the wireless module substrate (140) through the insertion portion (150) beyond the surface of the light source substrate (130) on which the light source (115) is disposed.SELECTED DRAWING: Figure 4
