For example, when two light-emitting groups emit light in a first color, adjacent first light-emitting groups (A) and second light-emitting groups (B) may emit light in a first color together. When the three emission groups emit light in the first color, adjacent first emission groups (A), the second emission group (B), and the third emission group (C) may emit light in the first color together. As another example, for example, when three light-emitting groups emit light in a second color, the second light-emitting group B, the third light-emitting group C, and the fourth light-emitting group D are together in the second color. It can be emitted as.

For cleanliness, the cleanliness level detected by the cleanliness sensor 90 is the most comfortable range, and then the pleasant range is the second level. As the cleanliness level decreases, the third level, the fourth level, and the fifth level It can be divided into. Here, the fifth level may be the lowest correction level.

When the cleanliness level is the first level, the light-emitting mechanism 60 includes light-emitting sources 111-114 of the first light-emitting group A, light-emitting sources 115-118 of the second light-emitting group B, and The emission sources 119-122 of the third emission group C and the emission sources 123-126 of the fourth emission group D may emit light in a first color.

When the cleanliness level 60 is the second level, the light emitting sources 111-114 of the first light emitting group A, the light emitting sources 115-118 of the second light emitting group B, and The emission sources 119-122 of the 3 emission group C may emit light in the first color, and the emission sources 123-126 of the fourth emission group D may emit light in the second color. .

In the light emitting mechanism 60, when the cleanliness level is the third level, the light emitting sources 111-114 of the first light emitting group A and the light emitting sources 115-118 of the second light emitting group B are first. The light emission sources 119-122 of the third emission group C and the emission sources 123-126 of the fourth emission group D may emit light in a second color. .

In the light emitting device 60, when the cleanliness level is the fourth level, the light emitting sources 111-114 of the first light emitting group A may emit light in a first color, and the light emitting sources of the second light emitting group B Both the (115-118), the light emitting sources (119-122) of the third light emitting group (C), and the light emitting sources (123-126) of the fourth light emitting group (D) may emit light in a second color. have.

When the cleanliness of the light emitting device 60 is the fifth level, the light emitting sources 111-114 of the first light emitting group A, the light emitting sources 115-118 of the second light emitting group B, and The emission sources 119-122 of the third emission group C and the emission sources 123-126 of the fourth emission group D may emit light in a second color.

 When the cleanliness level sensed by the cleanliness sensor 90 is varied, the light emitting device 60 may change colors of at least some of the plurality of light emitting sources 111-126. Among the plurality of light emitting sources 111-126, the color changing color may be changed after the luminous intensity gradually decreases. Among the plurality of light emitting sources 111-126, the light source whose color is changed may gradually increase after the color is changed.

For example, when the cleanliness level is changed from 3 level to 2 level due to clean operation of the air conditioner or a change in the indoor environment, the light emission sources 119-122 of the third light emission group C emit a second color. After stopping, the first color is emitted. At this time, the light emission sources 119-122 of the third emission group C gradually lower the illuminance of the second color emission, and thereafter switch to emission of the first color. The illuminance of the second color light emission can be gradually increased. That is, when the level of cleanliness is changed, the first color and the second color may not be changed suddenly, but may be changed gradually, and the fatigue of the eyes that the user may feel may be minimized.
