1 is a front sectional view of an air conditioning and lighting integrated luminaire unit according to an embodiment of the present invention, FIG. 2 is a perspective view of a housing used in the luminaire unit viewed from the indoor space, and FIG. It is a plan view, and FIG. 4 is a perspective view of the housing as viewed from the ceiling.

The air conditioning and lighting integrated luminaire unit according to the present invention is characterized in that the diffuser for ventilating the air of the indoor space and the lighting device for illuminating the indoor space are integrally formed.

1 to 4, the air conditioning and lighting integrated luminaire unit 100 according to the present invention includes a housing 10 corresponding to the outer body of the luminaire unit. In the housing 10, the lighting unit 10B and the air conditioning unit 10A are partitioned to accommodate the diffuser and the lighting device therein.

The shape of the housing 10 is implemented in a circular shape in the illustrated embodiment, but is not limited thereto, and may be formed in various shapes such as a rectangular shape, a rhombic shape, and the like. In this case, the material of the housing 10 is not limited thereto, but may be made of a metal material or a plastic material.

In the present invention, the housing 10 may be fixed to the lower surface of the ceiling covering material C with a bolt or the like by the fixing plate 12, and may be installed on the ceiling covering material C through a separate bracket. On the other hand, an internal accommodation space is formed between the ceiling finish material (C) and the side plate 11 by the side plate 11 extending downward from the ceiling finish material (C).

In addition, a porous planar distribution plate 20 may be provided at the lower end of the air conditioning unit 10A of the housing 10 . The porous planar distribution plate 20 shields the air conditioning unit 10A from the indoor space, supplies air supplied from the air conditioning system to the indoor space, sucks in air from the indoor space, and exhausts the air flow to the air conditioning system. It will act as a pathway.

In addition, the lighting unit 30 for illuminating the indoor space is coupled to the lighting unit 10B of the housing 10 . This will be described in more detail later.

In the present invention, the porous planar distribution plate 20 divides the inner space and the indoor space of the housing 10 so that the blowing pressure of the air supplied from the duct D is not directly transmitted to the indoor space, so that the air It plays a role of buffering the air supplied directly to the space.

Accordingly, according to the present invention, since the planar distribution plate 20 shields the inside of the housing 10, the inner space of the housing 10 has a static pressure higher than atmospheric pressure, which is the pressure of the indoor space when air is exhausted into the indoor space. It is maintained at (+), and on the other hand, when the air in the indoor space is sucked in, it is maintained at a negative pressure (-).

In this regard, the size and arrangement of the pores 21 perforated in the planar distribution plate 20 may vary according to the pressure of the air supplied from the air conditioning system. For example, when the pressure of the air supplied from the air conditioning system is high, it is necessary to reduce the size of the pores. On the contrary, when the pressure of the air supplied from the air conditioning system is small, it is necessary to increase the size of the pores.

Therefore, according to a preferred embodiment of the present invention, the pores 21 formed in the planar distribution plate 20 preferably have a diameter (a) of 6 to 10 μm. When the diameter of the pores 21 exceeds 10 μm, the blowing pressure supplied to the indoor space directly comes into contact with the user's skin, which is not preferable because the user may feel discomfort. In addition, when the diameter of the pores 21 exceeds 10 μm, fine dust, etc. contained in the air may be directly introduced into the indoor space without being filtered. In addition, if the diameter of the pores 21 is less than 6 μm, excessive pressure is applied inside the housing 10, which is not preferable. At this time, the separation distance (b) between the adjacent pores 21 and the pores 21 is 6 to 10 μm in a range similar to the diameter of the pores 21 in order to form a plurality of pores 21 in the planar distribution plate 20 .
