Technical Field

The present invention relates to a power supply unit for a duct rail, which is mechanically supported by a duct rail laid on a ceiling surface or the like and is electrically connected to the duct rail.

Background

The duct rail (wiring duct) is elongated and has a substantially コ -shaped cross section and is open downward, and guides slightly protruding toward the other open end and extending in the longitudinal direction are provided to extend from the open ends of the two opposite side walls of the portion having a substantially コ -shaped cross section, respectively, and a hollow rail having an opening is provided between the guides. The conductor lines are laid continuously in the longitudinal direction at positions opposed to the respective inner side surfaces of the two side walls of the pipe guide rail. Each conductor line is connected to an indoor wiring. Thus, the lighting fixture and the like can be installed at a desired place on the duct rail using the duct rail plug which is mechanically supported by the guide of the duct rail and can be electrically connected to the conductor wire.

Here, since AC power is supplied to the duct rail and DC power is used for the attached lighting fixture, an AC/DC converter is incorporated in the lighting fixture for the duct rail (see patent document 1). Further, since the lighting fixture for the duct rail is a lighting fixture using such an AC/DC converter, it is necessary to receive a suitability check of the PSE.

However, since the light emitting devices such as LED billboards indicating the store names are not mass-produced, and are often produced only by 1, it is not practical to accept the suitability check by the PSE with a time and cost for each production. Therefore, in the present situation, when installing a lighting device such as an LED signboard which is customized and produced in a small number of 1 or less according to the needs of a user, even if it is not easy to install a duct rail, another power supply process is performed.
