7 is built in, and intake ports 10 and 11, a lower surface air filter 13 and a side air filter 12 are provided on the lower surface and the side surface of the main body 1 of the luminaire, and an exhaust port 19 is provided on the top of the luminaire.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lighting fixture having a ventilation function installed in an office such as an office or a building.

[0002]

[Prior Art]

 In the office of the office, office work is performed for a long time under a constant illuminance, and the office is required to have a proper ventilation volume. Conventionally, lighting equipment for securing illuminance and equipment for ventilation are installed separately.

[0003]

[Problems to be solved by the device]

 Conventionally, many lighting, ventilation, and other equipment are installed on the limited ceiling surface of the office, but due to the arrangement of equipment with priority on illuminance, there is not enough space on the ceiling surface to secure a high level ventilation function, and this is for ventilation purposes. It is not possible to efficiently discharge harmful substances, odors, and cigarette smoke.

Further, since the construction of the lighting and the ventilation device is performed separately, it takes a lot of man-hours, and it is necessary to separately handle the instruments of the above-mentioned devices. The present invention has been proposed in view of the above problems of the prior art, and an object of the present invention is to provide a lighting device having a ventilation function in which the ventilation device is activated at the same time as the lighting fixture blinks. There is a point to do.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a lighting device with a ventilation fan according to the present invention has a ventilation device built into the lighting device, and an intake port and an air filter are provided on the bottom surface and side surface of the lighting device, respectively, and It is constructed by providing a ventilation port on the top of the device.

[0006]

[Action]

 Since the present invention is configured as described above, at the same time when the lighting equipment blinks, the ventilation system including the air inlet and the air filter provided on the lower surface and the side surface of the lighting equipment operates to operate the human body in the office. The proper illuminance and ventilation volume are secured. In addition, since a ventilation port is provided at the top of the lighting device of the present invention, the backside of the ceiling becomes a negative pressure, and the ventilation air is vertically sucked toward the ceiling, so that cigarette smoke flows into the office. There is not, and ventilation efficiency goes up.

[0007]

【Example】

 The present invention will be described below with reference to the illustrated embodiments. Reference numeral 1 is a main body of a horizontal triangular tubular lighting fixture with a ventilation fan, and a horizontal top piece 2 of the main body 1 is attached to a ceiling surface 4 via a ceiling mounting bracket 3. Fluorescent lamps 5 are mounted on both reflecting surfaces of the main body 1 as lighting equipment. In the figure, 6 is a socket, 7 is a ballast, 8 is a switch, and 9 is a switch cord.

In addition, a slit-shaped intake port 10 is provided on the lower surface of the luminaire main body 1, and a punching metal type intake port 11 is provided on the side surface, and the intake port is provided on the lower surface and the side surface inside the main body 1. A side surface air filter 12 and a lower surface air filter 13 are attached so as to oppose to 10, 11 via slit-shaped air filter insertion openings 14, 15 for the lower surface and the side surface, which are provided in the main body, respectively. In the figure, 16 is a fixture mounting bolt.

A small-sized, light-weight, low-noise type direct-acting sirocco fan 17 is installed in the lighting fixture body 1. Reference numeral 18 in the drawing denotes a drive motor for the fan. Further, an upper exhaust port 19 is provided on the upper surface of the luminaire main body 1. By appropriately adopting the changeover switch, blinking of lighting and switching of ventilation are performed.

[0010]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is possible to improve the working environment in the office by effectively disposing a device having both functions of illuminance and ventilation in a fixed ceiling space. In addition, since the lighting equipment and the ventilation equipment are not separately installed, the construction and installation man-hours can be reduced, and the lighting and ventilation handling operations can be performed at the same time.

Further, since the ventilation opening is provided at the top of the lighting fixture, the ventilation airflow is sucked toward the ceiling, so that cigarette smoke or the like does not flow into the office.
