Problems solved by technology

[0004] However, since light-emitting devices such as LED billboards displaying store names are not mass-produced, and only one is produced in many cases, it is unrealistic to spend time and money to receive PSE suitability inspections every time.

Embodiment 1

[0025]

[0026] figure 1 (A) is a partial sectional front view of the state where the DC lighting system 201 for the pipeline guide rail is installed on the pipeline guide rail 100, figure 1 (B) is a perspective view showing how the duct rail power supply unit 1 is attached to an electrified duct rail 100 laid on or suspended from the ceiling. Hereinafter, in the state where the power supply unit 1 for duct rail 1 is attached to the duct rail 100, the side of the duct rail 100 (top surface side) is regarded as the upper side of the power supply unit 1 for duct rail 100, and the side opposite to the duct rail 100 (ground side) The lower side of the power supply unit 1 is used as a pipe guide.

[0027] Such as figure 1 As shown in (A), the DC lighting system 201 for the pipe guide rail has a DC lighting unit 202, a suspension arm 207 fixed on the DC lighting unit 202 and extending upward (top side), and connected to the upper end of the suspension arm 207. The DC lighting u...

Abstract

The objective of the invention is to provide a duct rail DC light-emitting system (201) which is readily mounted onto and suited for a duct rail (100) and does not require a PSE conformity inspectioneven if a DC light-emitting unit (202) has been modified in shape, design, or the like. The duct rail DC light-emitting system (201) comprises: a duct rail power source unit (1) to be mounted on the duct rail (100); a DC light-emitting unit (202) which acquires DC power to emit light; and a DC light-emitting unit mounting plug (220) for mounting the DC light-emitting unit (202) onto the duct rail(100). The DC light-emitting unit mounting plug (202) has a dismount-prevention body (221) to be inserted into an opening (104), and said dismount-prevention body (221) has a dismount-prevention protrusion (222) which has a width allowing for insertion from the opening (104), and, when rotated in a horizontal direction, abuts the inner side surface of a guide (102) to prevent dismounting. Through-holes (225, 235, 243) are provided in the DC light-emitting unit mounting plug (220) so that DC power source lines (215a, 215b) can pass therethrough.

Description

technical field [0001] The present invention relates to a power supply unit for a pipe guide which is mechanically supported by a pipe guide laid on a ceiling or the like and which is electrically connected to the pipe guide. Background technique [0002] The duct rail (wiring duct) is a long strip with a substantially U-shaped cross-section and opens downward. The guiding piece slightly protrudes along the length direction, and a hollow guide rail is provided between the two guiding pieces. The conductor wires are laid continuously along the length direction at positions opposite to the respective inner surfaces of the two side walls of the pipe guide rail. Furthermore, each conductor line is connected to indoor wiring. Thereby, lighting fixtures and the like can be installed at desired places on the duct rail by using the duct rail plug which is mechanically supported by the guide of the duct rail and electrically connectable to the conductor wire. [0003] Here, since ...
