Description

  The present invention relates to an illumination device for illuminating a top plate surface of furniture with a top plate.

  Conventionally, various configurations have been known as modes for illuminating the top plate surface of furniture with a top plate. As an example, for example, a luminaire having a light source body having a light source and an arm that supports the luminaire body is prepared, and the base end of the arm of the luminaire is formed on a desktop panel above the top plate. What is made to attach via the lighting fixture attachment means which did is mentioned (for example, refer patent document 1).

  By the way, not only documents but also various instruments such as a personal computer are often arranged on the top surface, and the arrangement of the illumination apparatus can be changed so that the light from the illumination apparatus is not blocked by such an instrument. There is a demand to do. In the configuration described in Patent Document 1, the luminaire main body is moved by changing the posture of the arm. In such a configuration, the luminaire main body has a length of the arm from the luminaire mounting means. It can be moved only within a range of dimensions, and depending on the arrangement of the instrument on the top board, it may be impossible to illuminate a desired location on the top board.

Japanese Patent No. 3506060

  The present invention focuses on the above points and aims to solve such a problem, that is, to enable illumination of a desired location on the top board regardless of the arrangement of the appliances on the top board. To do.

  That is, the lighting device according to the present embodiment includes a power supply rail provided above the top plate of the furniture with the top plate, and a lighting device body having an electrode for receiving power supply from the power supply rail. The illuminating device main body can be attached to and detached from the power supply rail, and power can be supplied to the illuminating device main body regardless of where the illuminating device main body is attached to the power supply rail.

  If it is such, if a lighting apparatus main body is arranged in the position above the site | part which should be illuminated on a top-plate surface, and this lighting apparatus main body is mounted | worn with the said electric power feeding rail, it will illuminate which part of the said electric power feeding rail Since power can be supplied to the illuminating device main body even when the device main body is attached, a desired location on the top plate can be illuminated regardless of the arrangement of the appliances on the top plate.

  In order to more effectively illuminate a desired location near the use edge of the top plate, such as when the power supply rail is disposed above the counter use edge of the top plate, the lighting device main body is It is desirable to include a light source that emits light upon receiving power supplied from a power supply rail, and a reflector having a reflective surface that reflects light from the light source. This is because light from the light source can be reflected by the reflecting plate and guided to the vicinity of the use edge of the top plate.

  In particular, if the light source uses an LED element in the configuration of the previous stage, a light source using an LED element that consumes relatively little power is used, and light from the LED element that is highly straight traveling by the reflector is used. It is possible to reliably lead to the vicinity of the use edge of the top plate.

  In the case of adopting a usage mode in which one or a plurality of lighting device main bodies are attached to the same power supply rail when the lighting device main body is attached to and detached from the power supply rail as necessary, the lighting device main body includes a magnet unit. It is desirable to have further. If it is such, it is because the illuminating device main body which is not used can be made to adsorb | suck to the iron panel element etc. of the desktop panel provided above the top plate surface using this magnet part.

  In addition, a light source having a desired color temperature is provided according to the user's preference as long as a plurality of the illumination device main bodies each having a light source having a different color temperature can be used simultaneously or selectively. The lighting device body can be used by being mounted on a power supply rail, and a plurality of places on the top can be illuminated with light from light sources having different color temperatures.

  When placing a large device on the top plate surface, as a desirable mode when illuminating the use end side of the top plate than the large device, as a partition member provided between the top plate and the power supply rail An arm that can be attached and extends toward the use end side of the top plate, a power receiving unit that is attached to the tip of the arm, and that receives power supplied from the power supply rail, and the power received by the power receiving unit. What further includes an auxiliary power supply rail having a power supply unit for supplying to the main body is mentioned. If this is the case, the auxiliary power supply rail is disposed closer to the use end side of the top plate than the large-sized device, and the use end side of the top plate is attached to the auxiliary power supply rail by attaching the lighting device main body. This is because it can be illuminated.

  According to the configuration of the lighting device according to the present invention, it is possible to supply power to the lighting device body regardless of where the lighting device body is mounted on the power supply rail. A lighting device main body is arranged at a position, and the lighting device main body is mounted on the power supply rail to supply power to the lighting device main body, thereby illuminating a desired location on the top board regardless of the arrangement of the fixtures on the top board. You can
