Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an LED lighting apparatus.
[0002]
[Prior art]
Lighting fixtures using LEDs have been developed with a small size and long life. However, until now, the development of lighting devices mainly using auxiliary lighting (footlights, etc.) using orange LEDs and indicator lights using red LEDs have been mainly used.
[0003]
In recent years, blue LEDs have been developed, and then white LEDs have also been developed. White light can be obtained with LEDs, and it has been used for spot lighting and the like. However, the white LED currently being developed has a high temperature of the LED that is trying to obtain a high light output, and the resin covering the bare chip of the LED is rapidly deteriorated and the light output is lowered. For this reason, in lighting fixtures using white LEDs, it is difficult to say that there is no maintenance of the LED portion, but currently there are no products in which the LED portion can be exchanged for lighting fixtures that are currently commercialized.
[0004]
[Problems to be solved by the invention]
In the luminaire using white LEDs as described above, since the LED light emitting part is integrally incorporated in the luminaire, the replacement work of the LED cannot be performed alone, and the luminaire must be replaced for each luminaire or by a dedicated contractor. This is inconvenient for general users.
[0005]
Further, for example, there is an illumination device using LEDs disclosed in Japanese Patent Application Laid-Open No. 2001-52504. In this luminaire, the LED light-emitting portion can be exchanged. However, since this is an example that can be attached to a conventional socket for a general lamp, the socket needs to be incorporated in the luminaire, and the thickness of the luminaire is reduced. There is a drawback that increases.
[0006]
Accordingly, an object of the present invention is to provide an LED lighting fixture that can obtain a thin fixture structure by modularizing an LED portion used in the lighting fixture to have an exchange structure.

Moreover, the fitting state of a module and an instrument main body becomes good by making a LED module circular. Moreover, the deterioration of the contact state by one side of a module can be reduced, and shakiness becomes small.
[0010]
The LED lighting fixture according to claim 2 is the LED lighting fixture according to claim 1, wherein the power supply terminal portion is provided on the outer surface of the end portion of the LED module. As described above, since the power supply terminal portion is provided on the outer surface of the LED module end portion, it is difficult to come into contact when the LED module is tilted to the halfway end, and the abnormal mounting lighting state is difficult to be secured.

Moreover, even if there are a plurality of devices, one LED module can be used.
[0013]
The LED lighting fixture according to claim 5 is the LED lighting fixture according to claim 1, 2, 3 or 4, wherein the LED lighting fixture has a function of being electrically connected to the LED power supply unit via the connection terminal simultaneously with holding the LED module. The power supply terminal portion is connected to the outer shell member.

Thus, since the outer member is a lens provided on the front surface of the LED module, the energization is performed only after the lens is mounted. Further, it is not necessary to provide a separate outer member by using a lens.
[0015]
The LED lighting fixture according to claim 7 is the LED lighting fixture according to claim 1, 2, 3, 4, 5 or 6, wherein the feeding terminal portion is electrically connected by rotating the LED module around the central axis. Is done. As described above, since the power supply terminal portion is electrically connected by rotating the LED module around the central axis, the LED module can be easily and reliably operated.
