Through the housing. The light emitted from the red LED, blue LED, and green LED is polymerized in one place by the condenser lens to obtain light in which the colors of the red LED, blue LED, and green LED are mixed. It is done.

  The LED illuminator has a control unit, and the control unit controls the light intensity of the red LED, the blue LED, and the green LED, and changes the color and illuminance of the mixed light. The LED illuminator is incorporated in, for example, an image recognition mechanism portion of an electronic component mounting machine, and appropriately changes the light intensity of the red LED, blue LED, and green LED according to a signal from the image recognition mechanism portion. It is like that.

It is determined whether or not the positions corresponding to the selection buttons 59a, 59b, 59c, 59d, and 59e have been pressed for a long time. If it is determined that the positions corresponding to the memory selection buttons 59a, 59b, 59c, 59d, 59e of the operation unit 39 have been pressed for a long time, the process proceeds to step S31, and the memory selection buttons 59a, 59b, 59c, 59d. 59e, the RGB data corresponding to the operated button is overwritten with the editing RGB data and stored. If it is not determined that the positions corresponding to the memory selection buttons 59a, 59b, 59c, 59d, 59e of the operation unit 39 have been pressed for a long time, a normal tap operation has been performed. In this case, step S32 is performed. Migrate to In step S32, the data corresponding to the memory selection buttons 59a, 59b, 59c, 59d, and 59e out of the five RGB data stored in the memory 41 are read out, copied to the temporary work area of the memory 41, and edited. Let it be RGB data.

  When it is not determined in step S28 that there is an input at a position corresponding to the memory selection buttons 59a, 59b, 59c, 59d, 59e of the operation unit 39, or when the process of step S31 or step S32 is completed Shifts to Step S33.

  In step S33, it is determined whether or not the position corresponding to the data transmission / write button 61 of the operation unit 39 has been tapped. If it is determined that the position corresponding to the data transmission / write button 61 of the operation unit 39 has been tapped, the process proceeds to step S34, and “write communication” is performed on the lighting fixture 3 via the communication unit 54. "I do. That is, the five RGB data in the memory 41 are transmitted from the smartphone 5 to the lighting fixture 3 via the communication unit 54.

  When the process of step S34 is completed, or when it is not determined in step S33 that the position corresponding to the data transmission / write button 61 of the operation unit 39 has been tapped, the process proceeds to step S35.

  In step S35, it is determined whether or not the position corresponding to the data receiving / reading button 63 of the operation unit 39 has been tapped. If it is determined that the position corresponding to the data receiving / reading button 63 of the operation unit 39 has been tapped, the process proceeds to step S36 and "reading process" is performed. That is, “read communication” is performed on the lighting fixture 3 via the communication unit 54, and the RGB data received by the smartphone 5 from the lighting fixture 3 is stored in the memory 41.

  When the process of step S36 is completed, or when it is not determined in step S35 that the position corresponding to the data reception / read button 63 of the operation unit 39 has been tapped, the process proceeds to step S22. Repeat the process.

Next, the effect of this embodiment will be described.
First, the color and illuminance can be easily adjusted. That is, there is an operation unit 11 of the lighting device 3, and the color and illuminance of the light emitting unit 13 can be adjusted by the RGB data stored in the memory 17 by the operation unit 11, and the RGB data is edited by the smartphone 5 to edit the lighting device. 3 and the RGB data can be stored in the memory 17 of the luminaire 3, so that the color and illuminance of the light emitting unit 13 can be easily adjusted.
Further, in the smartphone 5, since an arbitrary color is set by performing a tap operation or a slide operation on a position corresponding to an arbitrary position on the color palette 53 of the operation unit 39, the color can be set by a simple operation. Can be more easily prepared.
Further, R data, G data, and B data can be individually adjusted by operating positions corresponding to the R fine adjustment button 55a, the G fine adjustment button 55b, and the B fine adjustment button 55c of the operation unit 39 of the smartphone 5. Therefore, fine color adjustment is easy.
Moreover, since the RGB data stored in the memory 17 of the lighting fixture 3 is selected and the light emitting unit 13 is caused to emit light based on the selected RGB data, the color of the light emitting unit 13 can be easily changed by a simple operation. Can be prepared.
In addition, since a plurality of RGB data is stored in the memory 17 of the lighting fixture 3, the color of the light emitting unit 13 can be adjusted by a simpler operation.
In addition, since a plurality of RGB data is also stored in the memory 41 of the smartphone 5, the color of the light emitting unit 13 can be prepared by a simple operation.
Further, since the illumination device 3 is provided with the illuminance decrease button 27a and the illuminance increase button 27b, the illuminance of the light emitting unit 13 can be easily adjusted on the illumination device 3 side.
In addition, since the illuminance can be adjusted by operating the positions corresponding to the illuminance decrease button 57a and the illuminance increase button 57b of the operation unit 39 of the smartphone 5, it is easy to adjust the illuminance of the light emitting unit 13 on the smartphone 5 side. .

The present invention is not limited to the one embodiment.
As the control unit, a dedicated controller or the like can be considered in addition to a smartphone.
As the operation unit, various cases such as a resistive touch panel are conceivable.
Various cases are conceivable for the operation interface screen.
Various cases can be considered for the color palette, such as a color swatch arranged on a lattice.
In addition, the combination of R data, G data, and B data of the editing RGB data is automatically changed over time, and when any color appears, the change of the editing RGB data is stopped. It is also possible to select a color.
In addition, the illustrated configuration is merely an example.

  The present invention relates to, for example, a visual inspection illumination device used for visual inspection of the surface of a product, and particularly relates to a device devised so that the color and illuminance can be easily adjusted, for example, suitable for inspection of the surface of a building material. It is.
