<P>PROBLEM TO BE SOLVED: To eliminate a sense of incongruity on an outer appearance by preventing light-emitting diodes emitting red-color light from being directly seen and improve an appearance. <P>SOLUTION: The device is provided with a first substrate 3 mounting red LEDs (Light-Emitting Diodes) 1 and a second substrate 4 arranged in opposition to the first substrate along an emission direction (an upward direction in Fig. 1) of the red LEDs 1 and mounting white LEDs 2 on a face (a top face in Fig. 1) opposite to a face (a bottom face in Fig. 1) opposing the first substrate 3. The red LEDs 1 mounted on the first substrate 3 are covered with the second substrate 4 mounting the white LEDs 2, and that, a plurality of through-holes 4c and the red LEDs 1 are arranged not to overlap with each other as seen from an opposing direction of the first substrate 3 with the second substrate 4, so that the red-color light emitted by the red LEDs 1 is prevented from being directly seen from the front (an upward direction in Fig. 1) to eliminate a sense of incongruity on an outer appearance and improve an appearance. <P>COPYRIGHT: (C)2007,JPO&INPIT |
