For example, as shown in FIG. 3, the shadowless lamp unit 3 includes a light source 31 for emitting light, a light source attachment unit 32 for attaching the light source 31, a radiation fin 33 for radiating heat generated by the light source 31, and the light source 31. 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 of the present embodiment having the above-described configuration, the light from the light source 31 which has passed through the slit plate 35 is reflected by the slit 36 of the slit plate 35 in a state where the light flux is limited. By irradiating and reflecting, the irradiation pattern of the shape corresponding to the shape of the slit 36 is formed to irradiate the object.

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

Next, the heat radiation operation of the shadowless lamp unit 3 according to the present embodiment will be described. The light source attachment portion 32 and the slit plate 35 are formed of, for example, a material having a high thermal conductivity, such as aluminum or copper. Therefore, by fixing the light source 31 in close contact with the light source attachment portion 32 and the slit plate 35, heat from the light source 31 passes through the light source attachment portion 32 and the slit plate 35 and is a radiation fin. It has a structure that transmits to 33 and dissipates.

In addition, with respect to radiation heat generated by the light source 31 irradiating the reflection mirror, the reflection mirror surface 34a or the back surface 34b is configured by applying a special coating that transmits or absorbs infrared rays. Thereby, the heat is dissipated from the reflection mirror back surface 34b.

In the above configuration, the shadowless lamp 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 lamp unit has a plurality of reflection mirrors and light sources. Also included.
