Description

Lighting fixture with air cleaner {LIGHTING APPARATUS HAVING AIR-CLEANER}

The present invention relates to a luminaire having an air purifier, and more particularly, to a luminaire having an air purifier configured to brighten a room and to clean indoor air and remove odors.

In general, the lighting fixture is installed on the ceiling, wall, etc. to illuminate the interior, and may be configured to adjust the illuminance according to the indoor atmosphere.

As the industry develops, bacteria, viruses, and bacteria that live in various dusts, fumes, tobacco smoke and dust in hospitals, laboratories, cooking rooms or offices, department stores, and toilets that require cleanliness in the aftermath of severe air pollution. , Air is easily contaminated by mold, etc. As a result, various infections of respiratory diseases and odors can occur, as well as secondary infections caused by pathogens through contaminated air, which can harm the user's health. have.

In order to solve this problem, conventionally, the air is sterilized and purified using filtering and electrostatic precipitating methods.

However, the above-described filtering and electrostatic precipitating methods have poor air sterilization and deodorization functions. Recently, air purification techniques using photocatalytic materials capable of being activated by light energy to sterilize and deodorize air have been developed and used.

As a representative example of the photocatalyst, titanium oxide is well known.

Photocatalysts such as titanium oxides have excellent adsorptive power with organic materials, and when exposed to light energy, they are excited to form various types of radicals, which can sterilize microorganisms by the strong oxidation power of radicals. While reacting, it can be decomposed to remove odors.

As is well known, when ultraviolet light is irradiated onto a metal oxide semiconductor such as titanium oxide, electrons in a valence band rise to the conduction band to generate holes, and oxidation Active species (radicals) are produced from oxygen or moisture in contact with the excited surfaces of metal semiconductors. The active species may oxidatively decompose organic substances, microorganisms, etc. attached to the surface.

The mechanism of photocatalytic reaction is as follows.

When light energy of a predetermined amount or more emitted from an ultraviolet lamp is irradiated to the photocatalyst, electrons are transferred to the conduction band to generate electrons and holes. Since these electrons and holes have very strong oxidation and reducing power, they react with water vapor (H ₂ O) or oxygen (O ₂ ) in the air to activate active oxygen such as OH-radicals, H-radicals, and superoxide enions (O2-). Occurs. And since these radicals have a strong binding force with other components, they can deodorize by breaking the bond of the odorous substance. In other words, OH-radicals break the binding of organic substances causing odors and directly bind, and finally only water vapor and carbon dioxide remain, and the odor component is removed.

In addition, OH-radicals have a strong oxidizing power and have a sterilizing function to sterilize microorganisms. That is, allergens and microorganisms are mainly composed of proteins in which amino acids are polypeptide-bound, and OH-radicals denature the proteins by breaking down the polypeptide bonds of these amino acids. Therefore, it can break down allergens and sterilize microorganisms.

In addition, the electrons or holes are directly bonded to the organic material to break the bond of the organic material, and eventually, water vapor and carbon dioxide are left to deodorize.

Eventually, the use of a photocatalyst enables sterilization, deodorization and allergen decomposition in the same principle as described above.

As described above, there is a technique of applying a photocatalyst to the surface of a general fluorescent lamp and one of the related arts to sterilize and remove odors by a photocatalytic reaction.

According to a fluorescent lamp coated with a conventional photocatalyst, the room can be illuminated by the light irradiated from the fluorescent lamp, while the photocatalyst reacts as described above by the ultraviolet rays contained in the light irradiated from the fluorescent lamp to sterilize the air around the fluorescent lamp. And odor is removed.

However, according to this prior art, there are the following problems.

Fluorescent lamps can not be used permanently, so when the life of the fluorescent lamp is over, it needs to be replaced with a new fluorescent lamp coated with a photocatalyst.

Since the photocatalyst reacts only by ultraviolet rays, the air can be sterilized and odors can be removed only when the fluorescent lamp is turned on. Since the lighting is turned on at the time when the fluorescent lamp is already contaminated and the odor is emitted, it takes a long time to sterilize the contaminated air for a long time and remove the odor even though it is excellent in sterilization and odor removal effect by the photocatalytic reaction. In particular, when the room is not in and out for a long time because the turbidity and odor of the air is severe, the air purification time accordingly takes longer. Therefore, contaminated air can only be sucked until the indoor air is sterilized and the odor is removed. Therefore, its effectiveness as an air cleaning means is poor. In addition, there is a drawback of drinking polluted air because the user does not turn on the fluorescent lamp during the day when it is not necessary to illuminate the room by the fluorescent lamp.

In addition, the conventional luminaire is a plate-shaped reflector is adopted so that the light emitted from the light can be widely reflected in the room, but the structure of such a reflector is difficult to illuminate the blind spot of the room, so do not illuminate the room brightly There are also disadvantages.

The present invention is to solve the problems as described above, the air purifier to sterilize the indoor air to remove the odor, and to reduce the maintenance cost by causing the photocatalytic reaction to occur by ultraviolet light irradiated from a common fluorescent lamp To provide a lighting fixture having its purpose.

In addition, another object of the present invention is to be able to brightly illuminate the room.

The machine room 14 may be provided with a ballast of the first lamp 20, etc., the first lamp 20 is installed in the sterilization chamber 15.

As the first lighting 20 serves as both indoor lighting and air sterilization, all lightings for illuminating the room and irradiating ultraviolet rays may be used, and preferably, a rod-shaped fluorescent lamp, a circular fluorescent lamp, and the like may be employed.

On the other hand, the inner surface of the sterilization chamber 15 and / or the louver-shaped reflector 30 of the luminaire having an air cleaner according to the present invention is active species capable of reacting by ultraviolet rays to sterilize the air / remove odors The resulting photocatalyst is applied. For example, if the application area of the photocatalyst is wide, the sterilization effect and the odor removal effect are further increased. Therefore, the louver type reflector 30 having the photocatalyst applied to the surface of the sterilization chamber 15 can be applied to the inside of the sterilization chamber 15. Can be formed.

As shown in FIG. 4, the louver type reflector 30 may be formed at a predetermined angle, for example, at a right angle with the first lighting lamp 20 so as to effectively perform the lighting function and the air cleaning function by the first lighting lamp 20. It may be composed of a plurality of reflecting plate members 31 arranged in a line at appropriate intervals along the longitudinal direction of the one lamp 20.

The first lighting unit 20 may be turned on / off by an operation of a switch for turning on / off the first lighting unit 20 when entering a room, such as a bathroom. That is, when the switch is turned on to enter a room such as a bathroom, the first light 20 is turned on to illuminate the inside of the bathroom by the light emitted from the first light 20, and the photocatalyst reacts by the ultraviolet light. The indoor air can be sterilized, odors can be removed, and when the switch is turned off, the first light 20 is turned off, and the indoor lighting / purification is not performed.

On the other hand, according to the lighting device having the air purifier according to the present invention, regardless of the lighting of the room lighting, the photocatalyst periodically reacts with ultraviolet rays to generate active species to sterilize the air and remove odors.

For example, as shown in FIG. 6, the sterilization chamber 15 may be provided with a second lamp 50 controlled to be turned on / off by a timer. Since the second lighting lamp 50 is intended for sterilization and deodorization, it is possible to use not only a general fluorescent lamp but also an ultraviolet lamp.

In addition, the inside of the case 10 may be provided with a storage unit for storing the toothpaste tube.

Although not shown in the drawings, a guide for guiding the flow of air may be further formed so that the sterilized air in the sterilization chamber 15 can be discharged quickly and smoothly.

The operation of the lighting device having an air cleaner according to the present invention configured as described above is as follows.

The luminaire 100 having an air cleaner according to the present invention may be operated by an on / off switch of indoor lighting or periodically by a timer. Hereinafter, the specific operation thereof will be described.

First, a case of operating by the indoor on / off switch will be described, for the convenience of the description will be described with an example that the lighting device having an air cleaner according to the present invention is installed in the toilet.

When the user turns on the switch to enter the toilet, power is applied to the first lighting unit 20 so that the first lighting unit 20 is turned on so that the light irradiated from the first lighting unit 20 is louvered reflector 30, a partition wall. Reflected by the 13 and the cover 12 to illuminate the interior of the toilet. Visible light emitted from the first lamp 20 is reflected by the louver reflector 30 to illuminate the room without blind spots.

On the other hand, ultraviolet rays included in the light irradiated from the first lighting lamp 20 is irradiated to the louver-shaped reflector plate 30 arranged side by side. In this case, the photocatalyst applied to the surface of the louver reflector 30 reacts with ultraviolet rays, and active species are produced in the sterilization chamber 15.

At the same time, the suction fan 40 is driven so that indoor air flows into the machine room 14 through the suction hole 11a of the main body 11 and is supplied to the sterilization chamber 15 through the air distribution hole 13a.

Since the active species are generated by the ultraviolet light of the first lighting lamp 20 inside the sterilization chamber 15, the microorganisms and bacteria contained in the air passing through the sterilization chamber 15 are removed by the active species to sterilize the air. , Odor is removed.

Clean air from which sterilization and odors have been removed from the sterilization chamber 15 is discharged into the toilet through the discharge hole 12a of the cover 12. In addition, a part of the clean air is supplied to the toothbrush barrel 60 through the discharge hole 12c of the toothbrush cylinder seating protrusion 12b and the suction hole 61 of the toothbrush barrel 60 to communicate with each other, the toothbrush barrel ( 60) the bristles of the toothbrush stored in the drying and sterilization.

By the driving of the suction fan 40, the air in the bathroom is continuously passed through the lighting fixture 100 having an air cleaner according to the present invention can be supplied with clean air.

After the user exits the toilet, when the first light 20 dot / off switch is turned off, the power applied to the first light 20 and the suction fan 40 is cut off and the first light 20 is turned off. Accordingly, air sterilization is not achieved.

On the other hand, even when not entering the toilet, the reaction by the photocatalyst is periodically performed by the timer to keep the air inside the toilet clean at all times, and its action is as follows.

When the rest period when the power is not applied to the second lamp 50 and the suction fan 40 while the time is checked by the timer has elapsed for a predetermined time, power is supplied to the second lamp 50 and the suction fan 40. Air cleaning is achieved.

When power is supplied to the second lighting lamp 50 and the suction fan 40, the indoor air is introduced through the suction hole 11a of the main body 11 by the driving of the suction fan 40, and the air distribution hole 13a is provided. It is supplied to the sterilization chamber 15 via.

At the same time, the light irradiated from the second illumination lamp 50 is reflected on the louver reflector 30 and the photocatalyst applied to the surface of the louver reflector 30 reacts with ultraviolet rays to generate active species. Microorganisms and bacteria contained in the air passing through the sterilization chamber 15 are removed to sterilize the air and odors are removed.

The clean air introduced into the sterilization chamber 15 and the sterilization and odor are removed is discharged into the toilet through the discharge hole 12a of the cover 12. In addition, a part of the clean air is supplied to the toothbrush barrel 60 as in the operation of the first lamp 20 to sterilize the bristles of the toothbrush housed in the toothbrush barrel 60.

Therefore, when the lifespan of the lamps 20 and 50 is completed and needs to be replaced, the lamps 20 and 50 are ordinary fluorescent lamps, thereby reducing the cost of replacing the fluorescent lamps to which the conventional photocatalyst is applied. Although the amount of ultraviolet light to be irradiated is smaller than that of the ultraviolet lamp, the contact area between the ultraviolet light and the photocatalyst is increased by the louver type reflector 30, so that indoor air can be sufficiently sterilized and odor can be removed.

In addition, since the air cleaning is performed periodically even when the lighting is not turned on / off for the indoor access, the indoor can be maintained as clean air.

As described above, according to the luminaire having an air cleaner according to the present invention, it is possible to maintain the device by replacing only the lamp, so that the cost of maintenance can be reduced, which is irradiated from the fluorescent lamp by the louver reflector The contact area between the ultraviolet light and the photocatalyst is increased, so a small amount of ultraviolet light can be used to sterilize the indoor air by using fluorescent lamps and remove odors.

In addition, since the indoor air is periodically purified to keep the indoor air clean even when not entering or leaving the room for a long time, reliability can be improved as an air cleaning means.

In addition, the light emitted from the lamp by the louver-shaped reflector is reflected without the blind spots, such that it is possible to illuminate the room more brightly.

While the invention has been described and illustrated in connection with a preferred embodiment for illustrating the principles of the invention, the invention is not limited to the configuration and operation as such is shown and described. Rather, it will be apparent to those skilled in the art that many changes and modifications to the present invention are possible without departing from the spirit and scope of the appended claims. Accordingly, all such suitable changes and modifications and equivalents should be considered to be within the scope of the present invention.
