Description

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

The present invention relates to a lighting device having an air cleaner, and more particularly to a lighting device having an air cleaner to brighten the room and to clean and deodorize the indoor air.

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.

On the other hand, as the industry develops, in the aftermath of severe air pollution, inhabitants such as hospitals, laboratories, cooking rooms or offices, department stores, and restrooms where people come and go frequently live in various dusts, smoke, tobacco smoke and dust. Air is easily contaminated by bacteria, viruses, molds, etc. This can cause various respiratory diseases and odors, as well as secondary infections caused by pathogens through contaminated air, which can harm the user's health. There is a problem that you feel.

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

However, the above-described filtering and electrostatic precipitating methods have weak air sterilization and deodorization functions. Recently, air purification technologies using photocatalytic materials which are activated by light energy and 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 oxide have excellent adsorptive power with organic materials, and when exposed to light energy, they are excited to form various types of radicals, which sterilize microorganisms by strong oxidizing power, and at the same time, radicals cause odors. This is because it reacts with odorous substances and decomposes them.

As is well known, when ultraviolet light is irradiated onto a metal oxide semiconductor such as titanium oxide, electrons in a valence band are raised to a 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 oxidatively decomposes organic matter, 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 generate active oxygen such as OH radicals, H radicals, and superoxide ions (O 2-). And since these radicals have a strong binding force with other components, it destroys the binding of the odorous substance is deodorizing effect is made. That is, the OH radical breaks the bond of the organic substance causing the odor and binds directly, thus leaving water vapor and carbon dioxide, and thus removing the odor component.

In addition, OH radicals have a strong oxidizing power to sterilize microorganisms, so they will act as sterilization. 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. Thus allergens are broken down and microorganisms are sterilized.

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 to sterilize air and to 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. Odor is removed.

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

Fluorescent lamps can not be used permanently, so the lifetime of the fluorescent lamp must be replaced with a new fluorescent lamp coated with a photocatalyst, which has a disadvantage of high maintenance costs.

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. At this point, when the fluorescent lamp is turned on, the indoor air is already contaminated and odor is emitted. Therefore, even though the sterilization and odor removal effect is excellent by the photocatalytic reaction, it takes a long time to sterilize the contaminated air for a long time and remove the odor. In particular, when the room is not in and out for a long time because the turbidity and odor of the air is extremely severe it takes a long time to purify the air accordingly. Therefore, since the indoor air is sterilized and the odor is removed, contaminated air can only be sucked in, so that its effectiveness as an air cleaning means is poor. In addition, there is a drawback of drinking contaminated air because the user does not turn on the 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 reflected into the room, but the structure of such a reflector is difficult to illuminate the blind spot of the room, the disadvantage that can not brightly illuminate the room There is also.

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

Another object of the present invention is to maintain clean indoor air at all times.

Another object of the present invention is to provide a bright lighting room.

Another discharge port through which sterilized air is discharged may be provided on the upper surface of the lamp case.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, terms or words used in the present specification and claims are defined in the technical spirit of the present invention based on the principle that the inventor can appropriately define the concept of the term in order to best describe his or her own design. It must be interpreted to mean meanings and concepts.

<Example 1>

As shown in FIG. 1, the lighting device 1 having the air cleaner according to the present embodiment includes a main body 10, a lamp 20 installed in the main body 10, a lamp ON / OFF switch S, and a main body. It is installed on the (10) to diffuse the light irradiated from the lamp 20, and to react to the surface by the ultraviolet light irradiated from the lamp 20 to generate active species to remove the sterilization / odor of the surrounding air It comprises a three-dimensional reflecting means 30 is applied to the photocatalyst.

As the photocatalyst, all those reacted by ultraviolet light may be used, for example, titanium oxide may be used.

As shown in FIG. 1, the main body 10 includes a lamp case 11 on which a lamp 20 is installed, a support plate 12 mounted on a table, and the like, and is placed approximately perpendicular to the support plate 12. 11 may be coupled to include a support rod 13 for supporting the lamp case (11).

The upper surface of the lamp case 11 may be provided with at least one discharge port 11a through which air therein may be discharged to the outside.

As shown in Figure 1 and 2, the three-dimensional reflecting means 30 may be composed of a plurality of reflective pieces 31 arranged in a line along the longitudinal direction of the lamp 20. Reflective pieces 31 may be integrally formed in the lamp case 11 or integrally formed in a separate reflecting plate 32 may be installed in the lamp case (11). Reflective pieces 31 may be approximately perpendicular to the lamp 20, the angle of the reflecting pieces 31 is not limited to the right angle and can increase the illuminance, while at the same time increasing the reflection area for ultraviolet light It can be formed at an angle.

When the reflective pieces 31 are formed through the reflective plate 32, the opening 32a is formed in the reflective plate 32 to communicate with the discharge port 11a of the lamp case 11.

The three-dimensional reflecting means 30 is to illuminate the room brightly by the light irradiated from the lamp 20, the greater the reflection area of the three-dimensional reflecting means 30 for the light irradiated from the lamp 20, the greater the reflection efficiency and photocatalyst Since sterilization efficiency increases, it is desirable to secure the reflection area to the maximum.

For example, as shown in FIG. 2, the connecting portions of the reflective pieces 31 and the reflective plate 32 may be formed in a curved shape without bending at right angles. When the connection part is bent at right angles, light may not be irradiated to the right angle connection part, and the light irradiated at the right angle connection part is not widely spread to the outside, but when it is curved, most of the irradiated light is reflected to the outside and is indoors. It can illuminate more brightly.

As shown in FIG. 3, the reflective plate 32 is formed in a curved shape, while as shown in FIG. 4, the reflective pieces 31 may have a concave surface.

As shown in FIGS. 1 and 3, the lamp receiving groove 31a may be formed in the reflective piece 31 so that the lamp 20 and the three-dimensional reflecting means 30 are as close as possible.

As shown in Figures 1 to 3, in the present embodiment, the indoor air is circulated by natural convection instead of forced circulation, so that the heat around the lamp 20 is not lost, that is, the air flows smoothly. A transparent cover 14 may be installed in the opening of the lamp case 11 so as to be transparent. As shown in FIG. 2, the cover 14 closes the opening such that at least one air inlet 11b is formed in the opening of the lamp case 11 (shown as formed in one place in the drawing). The cover 14 may be detachably coupled to the lamp case 11 for replacement of the lamp 20, for example, by bolts or slides.

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

When the on / off switch S is pressed to turn on the lamp 20, light is emitted from the lamp 20.

This light is reflected by the three-dimensional reflecting means 30 to illuminate the room. The contact area between the light and the three-dimensional reflecting means 30 is larger than a single plate, and the reflective pieces 31 of the three-dimensional reflecting means 30 are concave, and the reflecting plate 32 is curved to irradiate them. The light spreads widely to brighten the room. In addition, since the connecting portions of the reflective pieces 31 and the reflecting plate 32 are curved, the light irradiated to the connecting portions is also reflected to illuminate the room, thereby brightening the room.

At the same time, ultraviolet rays contained in the light emitted from the lamp 20 are irradiated to the three-dimensional reflecting means 30, so that the photocatalyst applied to the three-dimensional reflecting means 30 undergoes a photocatalytic reaction (ie, around the three-dimensional reflecting means 30). Active species are generated in the lamp case 11), and the air inside the lamp case 11 is sterilized by the active species, and odors can be removed.

On the other hand, since the energy generated by the lamp 20 is made of light and heat, the heat of the high temperature is generated inside the lamp case 11 to increase the temperature of the internal air. As such, when the temperature of the air inside the lamp case 11 is increased, the molecular motion becomes active and the molecular density decreases, so that the hot air sterilized by the cold air having a high density is pushed upward. That is, the external cool air flows into the lamp case 11 through the air inlet 11b of the lamp case 11 and pushes the sterilizing air inside the lamp case 11 upwards to the room through the discharge hole 11a. Exhausted. The polluted air introduced into the lamp case 11 is sterilized by the above-described action, and after the odor is removed, the air is continuously circulated while being discharged. At this time, since the part of the lamp case 11 except for the air inlet 11b is blocked by the cover 14, the air flow rate is increased so that the indoor air can be sterilized and odor quickly enough without forcibly circulating the air. Can be removed.

In the present embodiment, as described above, the air is not limited to being circulated by natural convection, and as shown in FIG. 5, the air can be forcedly circulated by the circulation fan F. The circulation fan F may be turned on / off in conjunction with the point / light off of the lamp 20 by the operation of the lamp on / off switch S (shown in FIG. 1), and may be turned on / off by a separate switch. It may be off.

The lamp case 110 is opened by the cover 120 only a part of the bottom portion (a part for sucking air).

The lamp body 100 may be detachably installed on an indoor wall, a ceiling, or the like, such as a toilet, and may be attached through, for example, the suction plate 130, and the cover 120 may include an luminaire having an air cleaner according to the present invention. The top surface can be made flat so that it can serve as a shelf.

6 and 7, when the partition wall 140 is integrally formed along the longitudinal direction of the lamp case 110 and coupled to the cover 120, the machine room 150 and the sterilization chamber ( 160 (shown in FIG. 7) may be partitioned. A ballast of the lamp 200 may be installed in the machine room 150, and a first lamp 200 may be installed in the sterilization chamber 160.

The first lighting lamp 200 serves as both indoor lighting and air sterilization, and may be used to illuminate the room and irradiate ultraviolet rays, and preferably, a rod-shaped fluorescent lamp or a circle-type fluorescent lamp may be employed. .

In the present embodiment, a photocatalyst may be applied to the inner surface of the sterilization chamber 160 and / or the outer surface of the three-dimensional reflecting means 300 to generate active species that react with ultraviolet rays to sterilize / remove air. .

As shown in FIG. 6, since the three-dimensional reflecting means 300 is made of the reflective piece 310 and the reflecting plate 320 as described in the first embodiment, a detailed description thereof will be omitted.

At least one three-dimensional reflecting means 300 may be installed at the circumference of the first lighting lamp 200.

In the lighting device 1 having the air cleaner according to the present embodiment, air may be circulated by natural convection as in Embodiment 1, or the air may be forcedly circulated by a circulation fan. Hereinafter, a forced circulation method using a circulation fan will be described as an example.

As shown in FIG. The inlet 111 is formed, the partition wall 140 is provided with an air distribution hole 141 for communicating the machine room 150 and the sterilization chamber 160, the cover 120 is air sterilized in the sterilization chamber 160 Discharge port 121 for supplying the room may be provided.

The first lighting 200 may be turned on / off by an operation of a switch (not shown) to turn on / off the first lighting 200 when entering or leaving the room. That is, when the switch is turned on to enter the room, the first light 200 is turned on to illuminate the interior of the bathroom by the light emitted from the first light 200, and the indoor air is reacted by the photocatalyst by ultraviolet light. Sterilization, odors can be removed, and when the switch is turned off, the first lighting 200 is turned off so that the room lighting / purification is not performed.

On the other hand, according to the lighting apparatus having the air cleaner according to the present embodiment, 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. 8, the sterilization chamber 160 may be further provided with a second lamp 400 controlled to be turned on / off by a timer. Since the second lamp 400 is intended to be sterilized and deodorized, a general fluorescent lamp as well as an ultraviolet lamp may be used.

The timer can be used both mechanically and electronically.

Since the second lamp 400 is operated by a timer, the first lamp 200 may be operated at the same time even when the first lamp 200 is on. In this case, different power circuits may be used so that an error does not occur in power supply. Since the motor of the circulation fan (F) is converted into a direct current through the adapter, when connected in parallel with each lamp (200,400) can use the existing circulation fan (F).

Here, although it was described that the air can be sterilized periodically by using a separate second light 400, the power supply circuit so that the first light 200 that is turned on / off periodically by the operation of the switch By changing, the effect by the 2nd lamp 400 can be acquired.

In the discharge port 122, a toothbrush barrel 500 may be installed in fluid communication so as to sterilize a toothbrush or the like stored in the toothbrush barrel 500.

Here, although the toothbrush barrel 500 has been described as being coupled to the discharge port 122, this is not limited to the toothbrush barrel 50, all products requiring sterilization may be applied.

In addition, the interior of the main body 100 may be provided with a receiving portion for storing the toothpaste tube.

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

The luminaire 1 having an air cleaner according to the present embodiment can be operated by an on / off switch of room lighting or periodically by a timer.

First, the case of operating by the indoor on / off switch is as follows.

When the user turns on the switch in order to enter the room, power is applied to the first light 200 and the first light 200 is turned on so that the light irradiated from the first light 200 is three-dimensional reflecting means 300, the partition wall Reflected by the 140 and the cover 120 to illuminate the room.

On the other hand, ultraviolet rays included in the light irradiated from the first lighting lamp 200 is irradiated to the three-dimensional reflecting means 300. In this case, as described in the first embodiment, the active species is generated in the sterilization chamber 160, and at the same time, the circulation fan F is driven so that the indoor air passes through the air inlet 111 of the lamp case 110. Is introduced into the machine room 150 is supplied to the sterilization chamber 160 via the air distribution hole 141.

In addition, a part of the clean air is supplied to the toothbrush barrel 500 through another outlet 122 to dry and sterilize the bristles of the toothbrush stored in the toothbrush barrel 500.

By driving the circulation fan F, indoor air may be continuously passed through the luminaire 1 having the air cleaner according to the present embodiment, so that clean air may be supplied to the room.

When the user turns off the first light 200 point / light switch, the power applied to the first light 200 and the circulation fan F is cut off and the first light 200 is turned off, thereby disinfecting the air. No action is taken.

On the other hand, even if the indoor switch is not on / off operation, the reaction by the photocatalyst is periodically performed by the timer to keep the indoor air clean at all times, the operation is as follows.

When the rest period when the power is not applied to the second lamp 400 and the circulation fan F while the time is checked by the timer has elapsed for a predetermined time, power is supplied to the second lamp 400 and the circulation fan F. Air purification is achieved.

When power is applied to the second light 400 and the circulation fan F, the indoor air is introduced through the air inlet 111 of the lamp case 110 by the driving of the circulation fan F, thereby providing air distribution holes 141. It is supplied to the sterilization chamber 160 via).

The air introduced into the sterilization chamber 160 is sterilized as described above and then supplied to the room.

Therefore, when the life of the lamp 20,200 applied to the present embodiments is completed and need to be replaced, since the lamp 20,200 is a general fluorescent lamp, the cost of replacing the fluorescent lamp coated with a conventional photocatalyst is reduced, and the lamp 20,200 is a fluorescent lamp. 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 three-dimensional reflecting means 300, so that the 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.

In addition, since the reflection area of the three-dimensional reflecting means 30,300 with respect to the lamp 20,200 can be brighter the room more brightly.
