The so-called straight tube fluorescent lamp type arranged on the mounting board (printed circuit board), Sirkeline (trade name) fluorescent lamp type (circular tube type) using an annular mounting board, sealing using a disk-shaped mounting board Various types and sizes such as types have been put into practical use.

  The present invention is suitable for a type having a mountain-shaped mounting surface, a ceiling direct mounting type commonly referred to as “reverse Fuji type”, and a ceiling embedded type in which the main body is embedded in a ceiling plate. It does not exclude other types in which a plate-like LED mounting substrate on which an element is mounted is mounted on a flat surface such as a light reflecting surface of a lighting fixture.

  For example, a fluorescent lamp illuminator having an inverted Fuji type light reflecting surface (surface for attaching a fluorescent tube) has two triangular inclined surfaces along the longitudinal direction with the top portion on the lower side. A lower surface including the inclined surface in which straight fluorescent tubes are respectively installed along the longitudinal direction of the inclined surface of the surface, and a driving power source (a lighting circuit including a so-called ballast) is accommodated therein. Is generally a light reflecting surface. Some have a protective cover (or light diffusion cover) attached to cover the fluorescent tube. This type of fluorescent lamp illuminator includes those that are directly attached to the ceiling surface and those that are suspended by a chain or the like.

  The ceiling-embedded type has an opening so that a fluorescent tube mounting surface such as a reflector for installing a straight tube fluorescent tube is exposed, and most of the lighting fixture body is embedded in a recess (or opening) provided in the ceiling. Is. Some of these lighting fixtures also have a protective cover (or a light diffusion cover) attached to cover the fluorescent tube. Usually, the drive power supply is housed inside the main body of the lighting fixture. Patent documents 1, patent documents 2, patent documents 3, patent documents 4, etc. can be mentioned as what indicated the conventional technology about this kind of LED lighting fixture.

  Patent Document 1 has an LED mounting board and a luminaire main body to which the board is attached, and at least a part of the side portion on the long side of the LED mounting board is covered with a push plate to determine the fixing position of the LED mounting board. Above, the LED lighting fixture which was attached using the screw | thread so that the said LED mounting board might be pressed on a lighting fixture main body, and was made to radiate | emit the heat | fever from an LED board with a fixture main body is disclosed.

  The LED lighting fixture disclosed in Patent Document 2 includes a light source unit that is detachably attached to the lighting fixture body. The light source unit includes an attachment member for attaching an LED substrate on which a plurality of LEDs are mounted to a lighting fixture body, and a power supply device (power supply unit) that supplies lighting power (drive power) to the LEDs. The attachment member of the LED substrate has a pair of side portions protruding in a direction orthogonal to the bottom surface portion from both sides in the width direction of the bottom surface portion formed in a long and rectangular plate shape. The power supply device has a storage case for storing the power supply board, and the storage case is attached to at least one side surface portion and is disposed in a space surrounded by the bottom surface portion and the pair of side surface portions.

  When replacing fluorescent tube lighting with LED lighting, it is common practice to replace each LED lighting fixture, that is, to replace the entire lighting fixture. In addition, a fluorescent lamp-shaped lamp comprising an LED substrate with a large number of LEDs attached instead of a fluorescent lamp illuminator in which a power supply unit is built in a luminaire as disclosed in Patent Document 4 and only a fluorescent tube is detachable. When replacing the lamp with the fluorescent tube, as described above, the fluorescent tube driving power supply unit housed on the back side of the lamp body is disconnected from the commercial power supply and the fluorescent tube feed line.

  A printed circuit board (hereinafter simply referred to as an LED board) on which a large number of LED elements are mounted is installed on a fluorescent lamp mounting surface (usually a light reflecting surface), and a power supply unit prepared separately from the LED board is used as a lighting fixture. In addition to the above-described disconnection of the fluorescent lamp driving power supply unit, the LED driving power supply unit needs to be newly installed in the main body of the lighting fixture, and the replacement work becomes complicated. In order to avoid such complications, the lighting fixtures are completely replaced.

  As a result, the cost for replacing the ceiling-mounted or ceiling-embedded fluorescent lamp luminaire with an LED luminaire is considerably high. In addition, the removed fluorescent lamp luminaire is discarded, and resources are wasted.

  In fluorescent lamps that are directly mounted on the ceiling or embedded in the ceiling, the main body structural members such as the housing (main body), transparent cover, and light diffusion cover that are the main body of the lighting fixture are the light emitter (fluorescent tube) and the power supply unit. It is desirable to be able to use these members as they are because they can be reused except for. In general, this type of lighting fixture has a large proportion of the price of the casing constituting the fixture body. If existing parts that do not require replacement are used as much as possible, the number of parts required for replacement and the number of construction processes can be reduced, and the overall cost of replacement can be reduced.

  In addition, the attachment of the LED substrate to a flat part such as a reflecting surface of a lighting fixture requires a lot of time for the attachment work because screws such as bolts and nuts are often used as described in the prior art. In addition, the necessity of ancillary parts such as screws also causes a reduction in the effect of reducing the number of parts.

  An object of the present invention is to provide an LED lighting apparatus having a structure that can be converted to an LED at a low price by reducing the number of construction processes and the number of replacement parts when the fluorescent lamp illumination is replaced with the LED illumination.

  In order to achieve the above-mentioned object, the present invention uses most of the parts including the lighting fixture main body attached to the installation member such as the ceiling as it is, and replaces the LED lighting with a minimum part replacement.
