Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a lighting fixture with an air purifier.

[Background technology]

Previously, for example, Utility Model No. 51-46383, Utility Model Number 52
There were lighting fixtures with air purifiers, such as No.-56544 and Utility Model Publication No. 186921/1983, in which lamps were arranged around the air purifying part.

However, when the air purifier has the suction port on the front surface of the device body, there is a drawback that the suction port becomes dark and the appearance is poor.

[Purpose of the invention]

An object of the present invention is to provide a lighting fixture with an air purifier that can brighten the suction port of an air purifier and has an excellent interior aesthetic appearance.

[Disclosure of the invention]

The lighting fixture with an air purifier of the present invention includes a main body, an air purifying section provided in the main body and having a suction port on the front side of the main body, and an air purifying section provided in the main body and having a suction port on the front side of the main body. Lamps arranged around the air purifier and an opening provided to cover the inlet of the air purifying section and communicating with the inlet, the periphery being an incident surface through which the light from the lamps enters, and the front surface being the front surface. It is equipped with a light-transmitting material serving as an output surface.

According to the configuration of the present invention, since the light-transmitting material having an opening is provided at the suction port of the air purifying section on the front surface of the device main body, the light from the lamp enters from the entrance surface around the light-transmitting material, and the light from the lamp enters from the front surface. Since the light is emitted from the output surface, the entire air purifier inlet becomes bright.
Therefore, the aesthetics of the room is improved and the working environment becomes better.

An embodiment of the present invention will be described based on FIGS. 1 to 4. In other words, 1 is the main body of the device, 2 is an air purifying section, 3 is a lamp of which an annular fluorescent lamp is an example, and 4 is a transparent cover having a discharge port 5 formed in the peripheral wall and a suction port 6 formed in the center of the lower surface. . The air purifier 2 has a motor 8 installed in the center of the device body 1,
A fan 10 is provided on the motor shaft 9, and its periphery is covered with a fan cover 12 having a communication port 11. Various filters 1 are attached to the lower end of the fan cover 12.
3 is provided, and a transparent cover 4 corresponding to the filter 13 is provided.
A translucent material 14, which is an example of a suction port grill plate, is provided at the suction port 6 so as to cover the suction port 6.
This light-transmitting material has an opening communicating with the suction port 6, and has a peripheral surface as an entrance surface and a front surface as an exit surface. For example, it may be formed of a transparent plate as shown in FIG. As shown in Figure b, a transparent plate with a roughened surface or a
It consists of a light scattering plate as shown in Figure c. 15 is a ballast, 16 is a lamp support spring, and 17 is a lamp socket.

When a switch (not shown) is turned on, the annular fluorescent lamp 3 lights up and at the same time the motor 8 operates. When the lamp 3 is turned on, light is distributed through the light-transmitting cover 4 , and the lamp light is also transmitted through the light-transmitting plate 14 . These rays are denoted by L. On the other hand, the fan 10 is rotated by the operation of the motor 8, and the air is discharged from the outlet 5 of the cover 4 while cooling the ballast 15, lamp 3, etc. inside the appliance body 1 from the communication port 11 of the fan cover 12, and the light is discharged from the outlet 5 of the cover 4. The dirty air from the room is sucked in, purified by a filter 13, sucked by a fan 10, and clean air is sent into the instrument body 1. Air flow is indicated by P.

Generally, the illuminance of a lighting fixture is high directly below it, and the illuminance decreases as it gets farther away. Therefore, it is normal to work directly under the lighting equipment. This is why it is preferable to install the purifier inside the lighting equipment in order to most efficiently clean it from contamination caused by work or smoking. Furthermore, by blowing purified air onto the surrounding lamps, the lamps are less contaminated and maintenance efficiency is improved. In addition, for lighting fixtures with air purifiers such as hanging types and ceiling-mounted types, the structure that sucks air from the center of the bottom, cleans it with various filters 13 such as activated carbon, and blows out from the four corners improves the purification efficiency of the entire room. Good. However, since the air intake grille is located in the center of the lighting, that area becomes dark, which not only makes the lighting as a whole inefficient, but also creates a sense of discomfort. Therefore, the light-transmitting material 14 is made of a transparent material, or a light-scattering material with a roughened surface.
By using a light-scattering material containing bubbles, scattering agents, etc., light entering from the side of the transparent material 14 is gently emitted from the front of the transparent material 14, and the illumination as a whole does not feel strange. Furthermore, suction from the bottom surface,
By blowing out from the periphery, the air flow is increased and the cleaning efficiency of the entire room is increased. Furthermore, the entire structure can be integrated into a thin structure.

FIG. 5 shows a modified example in which a straight tube type fluorescent lamp 3' is arranged around the air cleaning section 2 so as to surround it.

〔Effect of the invention〕

According to this invention, since the light-transmitting material having an opening is provided at the inlet of the air purifying section on the front surface of the device main body, the light from the lamp enters from the entrance surface that is the periphery of the light-transmitting material, and the light from the lamp enters from the entrance surface that is the front surface of the light-transmitting material. Because it emits more light,
The entire suction port of the air purifying section becomes brighter, which has the effect of improving the aesthetics of the room and improving the working environment.
