摘要： A grease filter, which includes a first channel having an inlet portion through which oil particles flow in, and a first guide unit configured to guide the oil particles flowing in through the inlet portion, and a second channel having an outlet portion through which the oil particles and air current flowing in through the inlet portion is discharged into the outside, and at least one second guide unit configured to guide the oil particles and air current to be discharged through the outlet portion. Here, the first channel and the second channel are detachably provided. The grease filter can be easily repaired and maintained, and collection efficiency can be improved due to such a configuration.

摘要： A lighting apparatus includes first and second light emitting areas, a color temperature controller, and a balance circuit. The first light emitting area includes first light-emitting arrays connected in series and outputs light of a first color temperature. The second light emitting area includes second light-emitting arrays connected in series and connected to the first light emitting area in parallel. The second light-emitting arrays output light of a second color temperature different from the first color temperature. The color temperature controller is selectively connected to at least one of an input node of the first light emitting area and an input node of the second light emitting area. The color temperature controllers determines an on/off state of the first and second light emitting areas. The balance circuit is connected to at least one of the first and second light emitting areas in series.
