A.1 [Reference] Measurement Environment for the Color Temperature
Data that was measured in the following environment is used for the color temperature sample file
(color_temperature_xxxxxK_) included with Applilet EZ for HCD Controller.
< Measurement environment >
 The whole measurement equipment is set up in a dark room where all outside light is cut off.
 A color sensor and lighting board are installed perpendicularly. A diffusion board is installed at the intersecting point,
tilted at 45.
 The distance L2 is set up so that the colors of the three LEDs are sufficiently mixed.
 The status of the mixed colors that is projected on the diffusion board is acquired by the color sensor.
 The lighting board is installed at a height so that the center of the LEDs and diffusion board are at the same height.
Caution The above measurement environment is intended for acquiring data to create a sample file and does
not guarantee the accuracy or reproducibility of colors.
Remark In the above measurement environment, the following multimedia display tester, made by Yokogawa Electric
Corporation, is used as the measuring equipment:
Multimedia display tester: 3298F (3298 02 (the main unit) + 3298 21 (the color sensor))
