Can be solved.

  It should be noted that the present invention is not limited to the above-described configurations and the configurations described in the embodiments described below, and it goes without saying that various modifications can be made without departing from the technical idea of the present invention. Yes.

  According to the light source device of the present invention, it is possible to reuse the equipment of the currently installed light source device, so that it is possible to obtain an extremely excellent effect that the waste can be greatly reduced.

  Further, according to the present invention, since the light emitting efficiency of the light emitting diode element can be effectively utilized to the maximum extent, an extremely excellent effect that energy saving can be achieved can be obtained.

  In addition, according to the present invention, it is possible to obtain an extremely excellent effect that the construction period can be significantly shortened with the replacement of the current light source device.

  Further, according to the present invention, it is not necessary to consider the replacement of the wallpaper accompanying the replacement of the current light source device, the replacement accompanying the ceiling, etc., so that it is extremely excellent that it can greatly contribute to cost reduction. Effect.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings of the examples.

  FIG. 1 is a diagram for explaining the configuration of a light source device according to a first embodiment of the present invention. FIG. 1 (a) is a plan view of a main part viewed from the front side, and FIG. 1 (b) is a plan view of FIG. It is an internal schematic plan view. 1 (a) and 1 (b), 1 is a box-shaped instrument having an opening 1a on one side, 2 is a reflector mounted so as to close the opening 1a of the instrument 1, and 3 It is a ballast for current fluorescent lamps having an input power supply line 3a and output power supply lines 3b and 3c that are installed inside the appliance 1 and are connected to an AC power supply AC.

  In addition, 4 is installed inside the instrument 1 and connected to the AC power supply AC, and the power supply unit to which the input power supply line 4a and the output power supply lines 4b and 4c are connected. 5 is exposed on the surface of the reflector 2 and installed. A pair of sockets 6 connected to the front ends of the output power lines 4b and 4c are disposed so as to be exposed on the surface of the reflecting plate 2, and red, green, red, for example, are formed inside the tubes at both ends of the cylindrical glass tube 6a.
