Description

  Embodiments described herein relate generally to an illumination device used in a hall, a theater, and the like, and an illumination control system using the illumination device.

Conventionally, lighting control systems have been installed in indoor facilities of halls and theaters.
This type of lighting control system includes a plurality of lighting devices arranged in an indoor facility, and an operation unit for operating a lighting device to be dimmed among the plurality of lighting devices to a dimming state having an arbitrary brightness. And a dimming control device that controls dimming of the corresponding lighting device based on an operation by the operation unit.

  An illumination load used as the illumination device includes, for example, a flood type illumination device. In this flood type illumination device, a plurality of lamps are arranged on the front surface of the lamp body. For such a flood type illumination device, an LED flood light using an LED as a light source is effective and practical in terms of high output and energy saving (see, for example, Non-Patent Document 1).

  However, in the conventional flood type illumination device, since the LED unit using the lamp or LED as a light source is fixed to the front surface of the lamp body, the lamp or LED unit cannot be removed at the time of failure. In particular, a large illuminating device required a lot of labor.

  In addition, the conventional LED floodlight is effective in terms of high output and energy saving. However, since the brightness is simply changed by controlling the dimming state, the color necessary for producing a more effective presentation is required. There is a problem that the temperature cannot be changed and, of course, the LED unit cannot be formed in a desired arrangement.
