In addition, the lighting device 1 includes a connection unit 6, a display unit 7, and an input unit 8, as shown in FIG.

  Here, as shown in FIG. 1, the direction in which the optical axis 10 of the lens 4 extends is referred to as the optical axis direction. In the optical axis direction, a side facing the direction in which the light source 3 emits light is called a front side, and a side facing the opposite direction in which the light source 3 emits light is called a back side.

  As shown in FIGS. 1 and 2, the housing 2 is formed as a rectangular box by a metal plate. The housing 2 has an opening on the front side and a light emitting window 2A. The casing 2 is formed so as to be closed except for the front side, and a ventilation hole for cooling is formed as necessary, though not shown.

  As shown in FIG. 1, the light source 3 is fixed inside the housing 2 and at the center of the housing 2. The light source 3 includes an LED module (not shown). The LED module is arranged on a surface of the light source 3 facing the lens 4. The LED module is a chip-on-board (COB: Chip On Board) type module and includes a substrate and a light emitting diode (LED). The substrate is formed in a flat plate shape. The light emitting diode is arranged on one surface of the substrate and mounted on the substrate. A plurality of light emitting diodes may be provided. In this case, the light emitting diodes are arranged at a plurality of different positions on one surface of the substrate and mounted on the substrate. The light emitting diode emits light in a direction indicated by an arrow A in FIG. 1 in parallel with the optical axis direction when power is supplied from the substrate.

  As the lens 4, as shown in FIG. 1, a convex lens, a Fresnel lens, or the like is used. The lens 4 is formed in a circular shape around the optical axis 10. The lens 4 is arranged on the front side of the light source 3 so as to be illuminated by the light emitted from the light source 3, and is arranged so that the optical axis 10 becomes the center of the light emitted from the light source 3. The lens 4 is disposed such that the plane 4A is on the rear side and faces the light source 3, and the convex surface 4B is on the front side and faces the outside of the housing 2 from the light emitting window 2A. Therefore, the light emitted from the light source 3 is projected from the light projection window 2A to the outside of the housing 2 via the lens 4.

The support tube 5D is inserted through the rotary shaft 5A and is screwed to the male screw 5Aa of the rotary shaft 5A. The lens 4 is fixed to the support tube 5D. Accordingly, when the rotation shaft 5A is rotated in one direction by the operation handle 5C, the support tube 5D moves to the front side in the optical axis direction with the lens 4 by screwing with the male screw 5Aa of the rotation shaft 5A. When the rotation shaft 5A is rotated in the other direction by the operation handle 5C, the support tube 5D moves to the rear side in the optical axis direction with the lens 4 by screwing the rotation shaft 5A into the male screw 5Aa. The adjusting means 5 may move the light source 3 in the optical axis direction with the light source 3 fixed to the support tube 5D.

The communication unit 11 is for inputting and outputting such control signals.

  The detection unit 12 detects the relative position between the light source 3 and the movement position of the lens 4 adjusted by the adjustment unit 5. In this case, the detection unit 12 is realized by, for example, a sensor that detects the rotation angle of the rotation shaft 5A. Alternatively, the detection unit 12 is realized by, for example, a sensor that detects a distance of the lens 4 from a predetermined reference position. The detection unit 12 is realized by a sensor that detects whether or not power is supplied to the above-described power supply device, that is, whether or not power is being supplied.

  The storage unit 13 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk.

The storage unit 13 stores a program for changing or switching the display of the display unit 7 based on input information by pressing each of the keys 8A, 8B, and 8C of the input unit 8 in association with each other. Further, the storage unit 13 stores, for example, a program for displaying on the display unit 7 in association with the power supply state to the power supply device detected by the detection unit 12. Further, the storage unit 13 stores, for example, a program for displaying on the display unit 7 based on input information (DMX communication state) from the communication unit 11 in association with each other. The storage unit 13 also emits light (beam) emitted from the light source 3 and emitted by the lens 4 based on, for example, the rotation angle of the rotation axis 5A detected by the detection unit 12 and the distance of the lens 4 from the reference position.

The storage unit 13 stores the color of the light emitted from the light source 3 and emitted by the lens 4 based on, for example, the rotation angle of the rotation axis 5A detected by the detection unit 12 and the distance of the lens 4 from the reference position. The temperature is stored in association with the temperature.

  The control unit 21 is a controller that controls each unit of the lighting device 1.

The display unit 7 is controlled so as to change or determine the display of the display unit 7 based on the acquired information. For example, in FIG. 4, when input is possible, the last digit “3” is blinked. After that, the number is increased from “3” in the increasing direction based on the number of times or the pressing time of the cursor key 8C in the upward direction. The numerical value of “3” is changed in the decreasing direction based on the number of times or the pressing time of the cursor key 8C in the downward direction. Further, the blinking is changed in the direction of increasing or decreasing the digit based on the number of times or the pressing time of the cursor key 8C in the horizontal direction. Then, the blinking is ended so that the current display is determined based on the pressing of the enter key 8B.
