Further, since the light source is provided with high illuminance, heat is generated in the light source portion together with the light. It may be provided with a heat dissipation structure for cooling this.
These electric energy and the generated thermal energy were not reused and were consumed as wasted energy.

Therefore, the present invention has been made in view of the above circumstances, and an object of the present invention is to convert the light energy and the thermal energy into electricity and provide them to each device.

In order to solve the above problems, the shadowless light power supply system according to the present invention is a power supply system having a power supply means detachable or incorporated in the shadowless light section, and is generated from the light source section of the shadowless light section. It has an energy conversion unit that converts at least one of thermal energy and optical energy into electricity, and the electricity converted from the energy conversion unit is supplied by the power feeding means.

According to the present invention, the wasted energy consumed can be converted into electricity, reused as a shadowless lamp power supply system, and provided to each device.

The shadowless lamp power supply system 2 is a system that converts wasteful energy of the shadowless lamp into electricity and supplies power to each device.

<Overall configuration>
The shadowless light power supply system 2 is, for example, as shown in FIGS. 1 and 2, a power supply system having a power supply means 5 detachable or incorporated in a shadowless light unit 3 provided in a dental clinic device 1. The surgical light unit 3 has an energy conversion unit 4 that converts at least one of the thermal energy and the optical energy generated from the light source 31 into electricity, and the electricity converted by the energy conversion unit 4 is the power feeding means. Power is supplied by 5.

<Shadowless light section>
As shown in FIG. 3, the shadowless lamp unit 3 includes, for example, a light source 31 that irradiates light, a light source mounting unit 32 that mounts the light source 31, a heat radiation fin 33 that dissipates heat generated from the light source 31, and a light source 31. It includes a reflection mirror 34 that reflects the light emitted from the light source in order to convert it into scattered light, and a slit plate 35 made of a material having a high thermal conductivity and having a slit of an arbitrary shape.

According to the shadowless lamp unit 3 according to the present embodiment having the above-described configuration, the light from the light source 31 passing through the slit plate 35 is transmitted to the reflection mirror 34 in a state where the luminous flux is limited by the slit 36 of the slit plate 35. By being irradiated and reflected, an irradiation pattern having a shape corresponding to the shape of the slit 36 is formed to irradiate the object.

In this embodiment, the light source 31 uses an LED, but the light source is not limited to this, and may be a light source other than the LED such as an incandescent lamp or a halogen lamp.

In this embodiment and the embodiments described later, the reflection mirror 34 has a substantially hemispherical shape as shown in FIG. 3, but the present invention is not limited to this, and a parabolic surface, a substantially parabolic surface, or the like. It is in a state of having a surface such as a spherical surface that makes light emitted from one point substantially parallel, and includes, for example, a curved surface in consideration of a combination of a radial curved surface and a wavy curved surface.

Next, the heat dissipation action of the shadowless lamp unit 3 according to this embodiment will be described. The light source mounting portion 32 and the slit plate 35 are formed of, for example, a material having high thermal conductivity such as aluminum or copper. Therefore, the shadowless lamp portion 3 is in close contact with the light source mounting portion 32 and the slit plate 35 to fix the light source 31, so that the heat generated from the light source 31 passes through the light source mounting portion 32 and the slit plate 35 and is radiated fins. It has a structure that is transmitted to 33 and dissipates.

Further, the radiant heat generated by irradiating the reflection mirror with the light source 31 is configured by applying a special coating that transmits or absorbs infrared rays on the front surface 34a or the back surface 34b of the reflection mirror. As a result, heat is released from the back surface 34b of the reflection mirror.

Regarding the above configuration, the shadowless light unit 3 illustrates the case where the reflection mirror 34 and the light source 31 are one, but the present invention is not limited to this, and the shadowless light unit has a plurality of reflection mirrors and light sources. It is also included if it is.

Further, the configuration of the shadowless lamp unit 3 is not limited to the above structure. For example, as shown in FIG. 4, the shadowless lamp unit 3 has a light source 31, and the irradiation light of the light source 31 enters the eyes of a patient or an operator. A shielding portion 37 may be provided on the front surface so that the light beam emitted behind the light source is reflected by the reflection mirror 34.

<Energy conversion unit>
The energy conversion unit 4 is composed of an element or the like capable of converting excess light energy or thermal energy generated from the light source 31 of the shadowless lamp unit 3 into electricity.

Can be done.

Further, as shown in FIG. 5, the thermal energy generating unit 43 shows the periphery of the light source 31, but the present invention is not limited to this, and the temperature difference is caused by the heat generated by the light emitted from the light source 31. It can also be attached to other places where it occurs. For example, as described above, the heat energy can be efficiently reused by attaching it to the back surface 34b of the reflection mirror or the like.

<Power supply means>
The power feeding means 5 may include a power supply terminal for connecting the electricity converted by the energy conversion unit 4 to the external device O. The connection terminal of the power cord of the external device O is plugged in and connected to supply power to the external device O.

Further, the power feeding means 5 is not limited to the one described above. For example, the power feeding means 5 may be wireless power feeding such as an electromagnetic induction method. This is because by making the power feeding means 5 wireless, it is not necessary to route the wiring of the external device.
