Description

  The present invention relates to a remote control lighting apparatus used in a production space such as a theater or a studio, and an illumination system configured using the remote control lighting apparatus.

  In this type of remote control lighting fixture in the past, as shown in FIGS. 6 and 7, for example, the horizontal rotation device 103 is mounted directly on the ceiling or holds a lighting fixture called a baton suspended from the ceiling. It is attached to the body. An arm 102 extending vertically downward is attached to the horizontal rotation device 103, and a lower end portion of the arm 102 is attached in the vicinity of the center of gravity of the instrument main body 101. In this remote control lighting apparatus, the arm 102 is horizontally rotated as indicated by an arrow H by the horizontal rotation device 103. In addition, a motor that drives the lower end of the arm 102 around the shaft is provided, and the instrument body 101 is rotated about the shaft 104 as indicated by an arrow R.

  However, in the remote control lighting fixture called the yoke type according to the above configuration, light control such as a zoom mechanism and a focus mechanism provided in the fixture main body 101 is performed in order to emit light with high projection image quality. If the part has high performance, the length of the instrument main body 101 (the length in the horizontal direction in FIG. 6) becomes long. When a plurality of remote control lighting apparatuses adopting this configuration are used side by side, the length of the instrument main body 101 is increased. A length obtained by adding a margin distance for avoiding contact to a length obtained by connecting a plurality of instrument main bodies 101 in the longitudinal direction is not practical. In addition, there is a problem that the countermeasure for heat is complicated because the tilt becomes various angles and the posture of the instrument body 101 changes. In particular, as shown in FIG. 7, when the light source unit 105 is located at the upper end, there is a concern that heat generated from the light source unit 105 may stay at the bottom of the horizontal rotation device 103, Heat measures are necessary.

  On the other hand, as shown in FIG. 8, a remote control lighting device of a type called a mirror type is attached to a ceiling by a suspension arm 202 or a baton suspended from the ceiling, as shown in FIG. It is attached. The instrument main body 201 is configured so as to reflect light by providing a 203 in the mirror housing 205 in front of the window 207. The mirror 203 is rotated horizontally as indicated by H by a motor about an axis extending in the vertical direction, and further, the mirror 203 is indicated by an arrow V about the axis 206 by another motor provided in the mirror storage unit 205. So that it is rotated. According to this configuration, the posture of the appliance main body 201 does not change, and is reduced in terms of the complexity of heat countermeasures compared to the yoke-type remote control lighting fixture shown in FIGS. 6 and 7. However, if light control units such as a zoom mechanism and a focus mechanism provided in the instrument main body 201 have high performance in order to emit light with high projection image quality, the length of the instrument main body 201 (the horizontal direction in FIG. The length) becomes longer, and there remains a problem that it is necessary to secure a wide installation place.

A remote control lighting apparatus using the mirror as described above is disclosed in Patent Document 1. This remote-control lighting device changes the irradiation range by changing the angle of the mirror, but when used by hanging downward, the irradiation range is limited because it cannot irradiate directly below. In addition, in order to emit light with high projection image quality, it is necessary to secure a wide installation place when the instrument body is long and hung horizontally.

  In the invention of claim 4, since the optical system and the optical control unit are continuously provided in the optical path for guiding the light emitted from the light source downward, the increase in size due to the addition of the configuration to the optical system is the length in the vertical direction. It can be absorbed by the change, and there is an effect that it is not necessary to expand the rotation range of the optical path changing unit without increasing the size of the optical path changing unit.

  According to the fifth aspect of the invention, the angle of the second mirror can be changed, and the light irradiation range, in particular, the non-irradiation range when the angle of the second mirror is fixed can be eliminated.

In addition to the second mirror 31, the optical control unit 30 is provided with a zoom mechanism unit 32 and a focus mechanism unit 33. The light reflected by the second mirror 31 passes through the focus mechanism unit 33 and the zoom mechanism unit 32 and is emitted to the outside from the light window 35 via the tip lens 34.

Further, in order to emit light with high projection image quality, even if the configuration in the optical system 13 is added, the size may be increased in the vertical direction and the length of the optical control unit 30 is not affected. For example, it is not necessary to secure a wide installation place in the lateral direction.

  In the present embodiment, the lamp 11 may be disposed at the position where the first mirror 21 is disposed. In this case, only a mechanism and a functional member that can be disposed in the optical control unit 30 such as the zoom mechanism unit 32 and the focus mechanism unit 33 can be provided.
