Description

[Detailed Description of the Invention] The present invention is directed to improving a lighting device equipped with a straight tube light source.
In particular, the present invention relates to a device configured such that the mounting position and mounting angle of a reflecting plate can be arbitrarily selected on the outer periphery of a straight tube light source in the longitudinal direction.

Conventionally, a lighting device equipped with a straight tube fluorescent lamp, for example, generally has a reflector T-fixed to the lighting device body, sockets are fixed near both ends of the lighting device body, and a fluorescent lamp is installed between the sockets. A lamp is attached.

However, according to the same structure, since the reflector is fixed to the lighting device body, the lighting characteristics are limited, and it is not possible to obtain many types of lighting devices with one lighting device.

Furthermore, in a conventional lighting device that illuminates the 011 plane.

Sockets for mounting a source are fixed on both sides of the lighting fixture body, and the reflector is configured to be able to rotate within a range of, for example, about 60 degrees with respect to the lighting fixture body.

For example, as shown in FIG. 1, a structure for rotating the reflector relative to the lighting fixture body includes a reflective lock latching body 2 having an angle adjustment scale on both sides of the lighting fixture body l, and the same reflecting mirror latching body. A reverberatory furnace 3 is mounted and supported on the reflector 2, and the reflector 31 is configured to move together within the range of an arcuate hole 4 formed in one wall of the reflector 3.

However, the illumination characteristics of the illumination device of the same structure are limited by the shape of the reflecting mirror, and the illumination direction can only be varied, making it suitable for wall illumination, but has the disadvantage that it cannot be used widely for other purposes.

Therefore, an object of the present invention is to provide a lighting device that has variable lighting characteristics and includes many types of lighting functions in one device.

Hereinafter) Figs. 2 to 13 of the present invention 1 will be explained.

FIG. 2 is a schematic diagram of a lighting device according to the present invention.
