Description

Ceiling-type sterilization and lighting device {LED LIGHTING APPARATUS COMBINED WITH STERILIZING FUNCTION}

The present invention is an edge-type LED lighting device integrated with an ultraviolet sterilizer installed on the ceiling to achieve the air sterilization effect of purifying the air by removing germs and odors in the air as well as indoor lighting of houses, buildings, etc. This relates to, and more specifically, to an LED lighting device for sterilization using UVC that reduces the time and effort required for direct installation on the indoor ceiling surface and can be easily and safely installed by the operator alone.

Today, various types of lighting are used to provide light at night or in a dark room or to illuminate objects. In particular, LED lighting that uses a light emitting diode as a light source not only saves energy by consuming less power than incandescent bulbs or fluorescent lamps, but also, unlike existing light sources, is a solid point light source that is sturdy, has a long lifespan, and is environmentally friendly. Due to its nature, it has significant advantages in terms of maintenance, etc.

However, lighting in the form of a simple combination of light-emitting diodes emits optically clear monochromatic light, causing unpleasant glare and eye fatigue to users, so it is not suitable for use when used as direct lighting or indirect lighting to create an indoor atmosphere. It is important to combine an appropriate lens or light guide plate to achieve light distribution.

Recently, by maintaining an appropriate distance between the light emitting diode and the light guide plate that diffuses the light, the light from the point light source generated from the light emitting diode is changed into the light of a planar light source (a light source whose light emitting part diffuses in a planar shape) through the light guide plate. Flat lights have been developed in various forms and are replacing existing fluorescent lights.

These LED flat lights are generally classified into direct-lighting type and edge-lighting type depending on the way the light-emitting diodes are arranged and the direction in which they emit light.

The direct type has limitations in slimming down because the LED dots are visible on the light emitting surface when the thickness of the product is reduced, and a separate space is needed to use the power supply unit (PSU).

The side-emitting type places the light-emitting diode on the side, so it has a relatively thin thickness, which is advantageous for slimming and thinning the product, and maintains long-life characteristics, so it has recently become a trend in large-area flat-type flat panels.

Meanwhile, UVC, a type of short-wavelength ultraviolet rays, is known to be effective in strongly sterilizing viruses and bacteria. In relation to this, Spectrum magazine, published by the Institute of Electrical and Electronics Engineers (IEEE), published research results by researchers at Columbia University in the United States showing that ultraviolet rays with short wavelengths can effectively eliminate viruses such as COVID-19 in the air without harming the human body. There is a bar.

Recently, lighting devices that utilize UVC LEDs to achieve virus sterilization functions have been in the spotlight.

For example, Patent Document 1 discloses a lighting device that also has an indoor air sterilization function.

Referring to FIG. 1, there is a case 100 having an air inlet 112 and an air outlet 113, air is introduced into the case 100 through the air inlet 112, and the air outlet ( A fan 190 that discharges air to the outside of the case 100 through 113), a board 120 located inside the case 100, and mounted on the board 120 through the air inlet 112. An ultraviolet light-emitting diode 130 that radiates ultraviolet rays to the incoming air, a lighting light-emitting diode 140 mounted on the substrate 120 and irradiating illumination light into the room, a sensor module 150 that detects whether a person is present in the room, As a result of the detection by the sensor module 150, if there is no person indoors, the ultraviolet light-emitting diode 130 is controlled to allow ultraviolet rays of one or more wavelengths of UVB (280 to 320 nm) or UV-C (250 to 280 nm) to enter. irradiates the air, controls the lighting light-emitting diode 140 to stop irradiating the illumination light into the room, and when there are people indoors, controls the ultraviolet light-emitting diode 130 to emit UV-A (320-360 nm) wavelength. It is configured to include a control unit 160 that irradiates ultraviolet rays to the incoming air or stops irradiating ultraviolet rays, and controls the lighting light emitting diode 140 to radiate illumination light into the room.

However, Patent Document 1 refers to the operation noise of the fan 190, which causes air to flow from the outside to the inside of the case 100 and exhausts the air drawn inside to the outside, and the noise generated during the forced flow of air. There is a problem that it is uncomfortable to use due to noise and its use in quiet indoor spaces is inevitably limited.

In addition, in order to install the lighting device (100) directly on the ceiling, first, pull out the wire wired on the ceiling, cut it to an appropriate length, remove the covering, and then install one worker while holding the lighting device (100). The PSU (power supply unit consisting of a constant current circuit to convert high-voltage alternating current into low-voltage direct current and supply a constant current to the LED) is attached to the upper surface (the surface facing the ceiling). After connecting the wires, the case (110) must be held in close contact with the ceiling surface while fixing it to the ceiling by individually driving screws into the rim. Not only is installation quite inconvenient and difficult, but it also requires two or more workers. As a result, installation costs rise due to labor costs, and the convenience and efficiency of work are inevitably reduced when installing on the ceiling.

In particular, in the case of houses such as apartments, the ceiling surface is made of gypsum board, which has a weak bearing capacity, so first accurately determine the attachment position of the lighting device 100 on the ceiling in advance, drive a plaster anchor, and then attach the case (case) to the ceiling surface using screws, etc. 110) must be fixed, but at this time, it is very difficult and difficult to accurately position the plaster anchor on the wide ceiling surface while holding the heavy lighting device 100.

And in the case of general houses where the ceiling surface is usually finished with a single plywood, the installation process is not only very complicated and inconvenient, such as having to damage the intact ceiling surface, but also requires a lot of work time.

Moreover, when inspecting or maintaining the lighting device 100, there is a problem in that the screws must be loosened one by one and then tightened again, which is inconvenient and inconvenient.

The background or prior art described above is information possessed by the present inventor or acquired in the process of deriving the present invention, and is only intended to help understand the technical significance of the present invention, and is information to which this invention belongs before filing the application for the present invention. It should be noted that this does not refer to technology widely known in the field, and in addition, the reference numerals in the prior art are unrelated to the reference numerals in the present invention.

Accordingly, the present inventor comprehensively considered all of the above-mentioned matters and at the same time, with the idea of solving the technical limitations and problems inherent in the existing ceiling-type sterilization and lighting device technology, the present inventor reduced the time and effort required for direct installation on the ceiling, thereby improving the convenience of work. We put a lot of effort into developing a ceiling-type sterilization and lighting device with a new structure that not only improves efficiency, but can be installed easily and safely even by a single worker, and can prevent falls due to its own weight by maintaining a solid and stable installation on the ceiling. As a result of constant research and effort, the present invention was created.

Therefore, the technical problem and purpose to be solved by the present invention is to provide a ceiling-type sterilization and lighting device that can be installed easily, conveniently, and safely at the exact location of the ceiling by a single worker.

Here, the technical problems and objectives to be solved by the present invention are not limited to the technical problems and objectives mentioned above, and other technical problems and objectives not mentioned can be understood from the description below as a matter of common knowledge in the technical field to which the present invention pertains. Those who have it will be able to understand it clearly.

A specific means according to an aspect of the present invention for effectively achieving a specific technical purpose while concretizing a new idea for solving the technical problem of the present invention as described above is provided with a case whose lower surface is made of a magnetic material. , a sterilization module that irradiates short-wavelength ultraviolet rays when power is supplied to the inside of the case, and a sterilization unit having a plurality of ventilation holes on the side of the case that radiate light generated from the sterilization module to the outside and allow air to pass through; A bracket fixed to the ceiling surface to support the sterilizing unit and made of a magnetic material, a first magnet fixed with bolts in parallel on both sides of the upper surface of the case through a through hole drilled in the center, and a position corresponding to the first magnet of the bracket A guide hole drilled smaller than the outer diameter of the first magnet, a slider formed to protrude upward from the head of the bolt higher than the thickness of the guide hole, and a slider integrally formed on the top of the slider, smaller than the inner diameter of the guide hole and larger than the outer diameter of the slider. The formed latch is connected to one side of the guide hole, and moves away from the guide hole so that the slider slides and the sterilizing unit overcomes the magnetic force of the first magnet and causes the latch to be caught in the bracket when separated from the bracket. Equipped with a mount hole that gradually narrows in width in the direction, is selectively attachable and detachable to the lower side of the sterilization unit, has an edge frame coupled to the edge of the light panel, and is equipped with an LED module including an LED lamp that generates light when power is supplied. A ceiling-type sterilizing and lighting device is proposed, which includes a plurality of second magnets fixed on the edge frame of the upper surface of the lighting unit to attach the lighting unit to the lower surface of the case with magnetic force.

As a result, the present invention can be installed quickly, easily, conveniently, and safely at the exact attachment position on the ceiling even by a single worker, thereby reducing the time, manpower, and cost required for direct installation on the ceiling surface, and improving the convenience and efficiency of installation work. The installed state can be maintained firmly and stably, preventing falling due to gravity.

In addition, as a preferred aspect of the present invention, a catch is formed on the inner surface of the mount hole that causes a phenomenon in which the slider directly contacts or interferes with each other, thereby maintaining the state installed on the ceiling more firmly and stably, so that the slider is not subject to its own weight. It can reliably prevent falls.

In addition, in a preferred aspect of the present invention, the insertion protrusion is formed to protrude downward at the lower part of the sterilizing unit and is inserted into the upper inner space of the lighting unit, and the upper end is fixed to the lower surface of the case, and the lower end is fixed to the lighting unit. By further comprising a plurality of wires fixed to the upper surface of the sterilizing unit and the lighting unit, not only can the sterilizing unit and the lighting unit be joined without gaps or steps, but it is also possible to prevent the lighting unit from completely falling off from the sterilizing unit, thereby improving safety.

According to the technical idea and embodiment of the present invention, which is based on a unique solution to solve the above-described technical problem, the bracket is fixed by driving a screw in a state in close contact with the ceiling surface, and the sterilization unit is fixed. It can be installed directly on the ceiling by simply inserting the slider and latch mounted on the case into the guide hole of the bracket.

In other words, the sterilizing unit can be temporarily installed while hanging on the bracket due to the magnetic force of the first magnet mounted on the edge of the case, and the sterilizing unit can be maintained firmly fixed to the ceiling by sliding the slider along the mount hole. there is.

In addition, the lighting part can be quickly and easily attached to the bottom of the case using the magnetic force of the second magnet.

Therefore, a single worker can easily, easily, and safely install on the ceiling, reducing fatigue during installation work and improving convenience and efficiency. In addition, the time required for installation can be shortened, and installation manpower and costs (labor costs) can be significantly reduced. there is.

Moreover, the sterilizing unit installed on the ceiling is maintained by the magnetic force of the first magnet, and even if it overcomes the magnetic force (attractive force) between the first magnet and the bracket due to its own weight or external force and is separated from the bracket, the latch is secondarily caught on the bracket, so gravity is removed from the ceiling. It can prevent falling.

Furthermore, with the latch of the sterilizing unit passing through the guide hole of the bracket, the attractive force between the first magnet and the bracket acts, and the entire sterilizing unit is slidably moved by the guidance of the slider and mount hole, so the sterilizing unit can be installed on the ceiling. In the process, the positions of the guide holes and latches, which are hidden from view on the bottom of the case, can be adjusted easily and naturally, and this allows the operator alone to simply and easily install them at the exact location on the ceiling.

As shown in Figures 2 to 9, the main components constituting the ceiling-type sterilization and lighting device according to an embodiment of the present invention are a sterilization unit 10, a bracket 20, a guide hole 21, and a mount hole ( 22), it includes a first magnet 30, a slider 35, a latch 36, a lighting unit 40, and a second magnet 50.

The sterilizing unit 10 obtains a sterilizing function using short-wavelength ultraviolet rays, and is provided with a hexahedral case 11 with a lower surface made of a magnetic material and an empty interior, and the inside of this case 11 is supplied with power. It has a built-in sterilization module (12) that irradiates short-wavelength ultraviolet rays in the range of 100 to 290 nm into the air.

And on the side (side wall portion) of the case 11, a number of ventilation holes 13 are formed to radiate light generated from the internal sterilization module 12 to the outside and allow air to pass through.

That is, air enters and exits the internal space of the case 11 through the ventilation hole 13 due to natural convection, and at this time, bacteria and viruses contained in the air are sterilized by short-wavelength ultraviolet rays irradiated by the sterilization module 12. and odor removal function can be obtained.

And the case 11 is made of an opaque material or coated with an opaque material to prevent the short-wavelength ultraviolet rays emitted from the sterilizing module 12 from being exposed to the outside, and is formed to accommodate the sterilizing module 12 as if surrounding it. .

That is, the short-wavelength ultraviolet rays generated from the sterilizing module 12 are not exposed or irradiated in the direction directly below the case 11, thereby minimizing the effects and side effects on the human body.

In addition, since the light generated from the sterilization module 12 is radiated to the outside through the ventilation hole 13, an indirect lighting effect that creates a warm indoor atmosphere can be obtained because the light is soft and glare is reduced.

And, at the lower part of the case 11, an insertion jaw 14 that is inserted into the inner space of the skirt 44 of the lighting unit 40 is formed to protrude downward.

That is, when installing the lighting unit 40 on the lower side of the sterilizing unit 10, the insertion jaw 14 is inserted into the upper inner space of the lighting unit 40 created by the skirt 44 of the lighting unit 40, The connection parts can be maintained in a smooth and natural state without gaps or steps.

And the lower surface of the case 11 is made of a magnetic material such as iron so that the second magnet 50 sticks.

In addition, a leading edge 15 protrudes from the upper edge of the case 11.

In addition, there is a wire hole (unmarked) in the center of the upper and lower surfaces of the case 11 that allows wires wired on the ceiling to be drawn out and passed through and connected to the sterilizing module 12 and the LED module 43, respectively.

Here, the surface of the case 11 can be treated with zinc coating or antioxidant coating to prevent deformation due to heat from the light irradiated from the sterilization module 12 and corrosion due to moisture.

In addition, the sterilizing unit 10 may further include an air circulation unit that forcibly circulates the internal air and external air of the case 11.

That is, the air circulation unit can efficiently sterilize harmful bacteria floating in the indoor space by discharging internal air sterilized by short-wavelength ultraviolet rays generated from the sterilizing module 12 and sucking in and sterilizing new external air.

In addition, the air circulation unit can perform a heat dissipation function by dissipating heat generated inside the sterilizing unit 10.

In addition, the sterilization module 12 may include a board on which a number of UVC LED lamps are mounted, which emit deep ultraviolet rays (short wavelength in the range of 100 to 290 nm) that are harmless to the human body when power is supplied, or may include a mercury lamp that emits ultraviolet rays. .

For example, the sterilization module 12 may have a structure in which electrodes are installed at both ends of a transparent quartz tube, mercury, a metal halide additive, and an inert buffer gas are filled inside, and both ends are sealed.

At this time, if a high-purity quartz tube with a SiO2 content of about 99.97% or more is applied, ultraviolet rays in the 253.7nm wavelength band, which have excellent sterilizing power, can be effectively emitted.

Meanwhile, the sterilizing unit 10 has a separate shielding cover (not shown) that closes the lower surface of the case 11 to block short-wavelength ultraviolet rays of about 100 to 290 nm generated from the sterilizing module 12 from being irradiated in the direct direction. ) may further be included.

In other words, the shielding cover completely closes the lower surface of the case 11 and limits the radiation range of short-wavelength ultraviolet rays of about 100 to 290 nm generated from the sterilization module 12 to the side, so that harmful ultraviolet rays are irradiated directly toward the human body. Safety can be strengthened by blocking this.

Here, the shielding cover is preferably made of a material with a high UV blocking rate, such as opaque PC or PMAA, which cannot transmit short-wavelength UV rays and prevents discoloration or damage by UV rays.

The bracket 20 is installed directly on the ceiling surface of an indoor space, and is provided to support the sterilizing unit 10 while attached to the ceiling surface.

And the bracket 20 is made of a magnetic material such as iron so that the first magnet 30 sticks to it.

In addition, the height of the bracket 20 is slightly lower than the height of the leading edge 15 of the case 11 so that the sterilizing unit 10 is installed in close contact with the ceiling surface.

That is, in order to ensure that the bracket 20 is surrounded by the leading edge 15 of the case 11 when the sterilizing unit 10 is installed and is not visible from the outside, the height of the upper and lower thickness is equal to the leading edge 15 of the case 11. Lower than the height, the length and width are preferably formed shorter and narrower than the spacing between the leading edges 15 facing each other.

In addition, the sterilizing unit 10 is attached to both edges or all four corners of the bracket 20 with the magnetic force of the first magnet 30, and at the same time, when pushed in the forward and backward directions, the slider 35 and the latch 36 are inserted and locked. The guide hole 21 and the mount hole 22, which maintain the state, are formed to communicate with each other.

In addition, the bracket 20 is provided with a number of screw holes (not marked) and wire wiring holes (not marked) so that it can be easily fixed with screws to reinforcement wood on the ceiling.

This bracket 20 can be formed from a thin metal plate such as a steel plate using a plastic processing method such as press sheet metal processing.

In addition, the bracket 20 may be formed in a bent shape so that its cross section has a '└┘' shape in order to reinforce strength and rigidity.

Meanwhile, the guide hole 21 is drilled at a position corresponding to the first magnet 30 among both edges or all four corners of the bracket 20 and is smaller than the outer diameter of the first magnet 30.

That is, the inner diameter of the guide hole 21 is smaller than the outer diameter of the first magnet 30 so that the first magnet 30 sticks to the bracket 20 and the slider 35 and the latch 36 pass through. It is formed in the shape of a round hole that is larger than the outer diameter of.

In addition, the mount hole 22 is such that when the slider 35 slides and the sterilization unit 10 overcomes the magnetic force of the first magnet 30 by its own weight and is separated from the bracket 20, the latch 36 is attached to the bracket 20. ) It is connected to one side of the guide hole 21 in order to hang it on the hook.

That is, the mount hole 22 gradually narrows in width in a direction away from the center of the guide hole 21, and is formed in a shape that is larger than or equal to the outer diameter of the slider 35 and smaller than the outer diameter of the latch 36.

Meanwhile, as shown in FIG. 10, a catch 23 is formed on the inner surface of the mount hole 22 to maintain the locked state by directly contacting or interfering with the slider 35.

That is, the catches 23 are formed in the shape of a semicircular groove, with at least one of them facing each other on the inner surface of the mount hole 22, so that the sterilizing unit 10 is attached to the bracket ( The state of hanging on 20 is maintained more firmly and stably, and this prevents the sterilizing unit 10 from easily moving or separating from the bracket 20 due to external force.

The first magnet 30 is mounted side by side on both edges of the upper surface of the case 11 to fix the sterilizing unit 10 to the bracket 20.

That is, the first magnet 30 is formed in the shape of a disk, and is fixed to both edges of the upper surface of the case 11 with bolts 32 through a through hole 31 drilled in the center.

And a counter sink 34 is formed on the edge of the through hole 31 to bury the head 33 of the bolt 32 under the surface of the first magnet 30.

Here, the first magnets 30 are preferably provided in pairs at regular intervals on both sides of the upper surface of the case 11 for convenience and stable support when installing the sterilizing unit 10 on the bracket 20.

In addition, the first magnet 30 is preferably made of a permanent magnet such as a magnetic magnet or neodymium magnet with excellent heat resistance and corrosion resistance.

The slider 35 protrudes from the head 33 of the bolt 32 higher than the thickness of the guide hole 21.

That is, when the sterilizing unit 10 is installed on the bracket 20 using the magnetic force of the first magnet 30 and is pushed in the horizontal direction, the slider 35 guides a smooth sliding movement and is directly connected to the mount hole 22. It is formed integrally with the head 33 of the bolt 32 to maintain the sterilizing unit 10 locked to the bracket 20 by contacting or interfering with each other.

The latch 36 is used to ensure that the sterilizing unit 10 overcomes the magnetic force of the first magnet 30 due to its own weight or external force and does not fall even if it is separated from the bracket 20 and remains hanging on the bracket 20. It is formed integrally at the top of the slider (35).

That is, the outer diameter of the latch 36 is smaller than the inner diameter of the guide hole 21 and larger than the outer diameter of the slider 35.

In addition, a tool insertion groove 37 is formed on the upper surface of the latch 36 to allow various tools such as an electric screwdriver or a hex wrench to be inserted to quickly and easily turn the bolt 32.

The lighting unit 40 uses the light of a light emitting diode (LED) to brightly illuminate the room, and is formed by combining an edge frame 42 with the edge of the light panel 41 for selective attachment and detachment to the lower side of the sterilizing unit 10. It consists of:

And the edge frame 42 is equipped with an LED module 43 including a board on which a plurality of LED lamps that generate light when power is supplied are mounted.

That is, the lighting unit 40 includes a light panel 41 that induces the path, scattering, and diffusion of light, an edge frame 42 that surrounds and supports the four side edges of the light panel 41, and emits light when power is supplied. It is configured to include an LED module 43 that irradiates light toward the side of the light panel 41.

Here, the light panel 41 has the function of converting a point light source into a surface light source by inducing the path, scattering, and diffusion of light.

In other words, the light panel 41 has a light distribution characteristic that spreads the light of the point light source emitted from the LED module 43 built into the edge frame 42 evenly over the entire surface so that it is evenly and stably emitted as the light of the surface light source. is implemented to maximize lighting efficiency by minimizing the loss of light generated from the LED module 43.

This light panel 41 includes a light guide plate that transmits and evenly emits the light emitted from the LED module 43 to the entire surface, and is laminated or attached to the upper surface of this light guide plate to prevent light incident (leakage) through the light guide plate. A reflector that reflects light to the light guide plate, and is disposed below the light guide plate, scatters and diffuses the light incident through the light guide plate and converts the light from the point light source emitted from the LED module 43 into the light of the surface light source to illuminate the outside of the room, etc. It may be configured to include a diffusion plate that evenly emits light toward the target.

It may further include a back cover that is laminated or attached to the upper surface of the reflector to prevent light emitted through the light guide plate from being lost to the upper surface, and to provide a heat dissipation effect as well as protect the upper surface of the light guide plate.

That is, the light generated from the LED modules 43 located on both sides of the light guide plate flows into the interior of the light guide plate, is scattered and diffusely reflected as it hits the reflector stacked on the upper surface, and is converted into a surface light source through the diffusion plate on the lower side of the light guide plate. It is emitted to the front.

Here, the light guide plate can be formed of a transparent resin such as acrylic resin (PMMA), polycarbonate resin, or amorphous polyolefin resin, and can be formed into a certain pattern by processing a dot printing method or a "V"-shaped groove on the surface or back surface. may form.

In addition, the reflector and diffuser plate can be implemented in the form of a film. In particular, examples of the diffuser plate include a combination of transparent thermoplastic resin and low-molecular liquid crystal, or polyvinyl alcohol and low-molecular liquid crystal, and an acrylic diffuser or light-absorbing material can be added. It can be implemented by including it or by forming a fine pattern.

In addition, the back cover can be formed to function as a heat sink using an aluminum plate with excellent thermal conductivity in order to smoothly dissipate the heat generated by the LED module 43, and the edge portion of the back cover is formed along with the light guide plate to form an edge frame 12. Maintains the state of being stably inserted into.

The LED module 43 is built into the edge frame 42 and emits light when power is supplied to evenly radiate light toward the side of the light guide plate of the light panel 41.

That is, the LED module 43 is located within two edge frames 42 facing each other on at least one of the four edge frames 42 that surround and support the four side edges of the light panel 41 in the form of a square frame. Each is inserted and installed, so that light is evenly incident on the inside of the light guide plate when power is supplied.

The light incident from the LED module 43 is reflected and refracted by the reflector, diffused by the diffuser, and uniformly emitted toward the room.

Here, the LED module 43 may include an LED strip bar in which a plurality of light-emitting elements are mounted at regular intervals on a strip-shaped PCB circuit board, and the light-emitting elements include high-brightness white LED (Light Emitting Diode) chips. It is most preferable to use, but in addition, organic EL (Electroluminescence), etc. can also be employed.

The light-emitting elements of the LED module 43 are connected by circuit wiring on the PCB circuit board, and the ends are connected to the power supply unit by a connector (not shown) to receive power or exchange electrical signals. A separate heat dissipation member may be provided to dissipate heat generated from the light emitting device to the outside.

The edge frame 42 surrounds and supports the side edges of the light panel 41 on all sides and embeds the LED module 43 to protect it.

That is, the edge frame 42 is a combination of at least three or more pieces and is formed in the form of a polygonal frame with a lighting space in the center.

Also, on the side of the edge frame 42 opposite to the side of the light panel 41, a groove is formed for embedding the LED module 43, and a power supply device (SMPS) is installed at a certain height on the upper edge. A skirt 44 for enclosing the interior is formed integrally.

Meanwhile, in a preferred embodiment of the present invention, the edge frame 42 is shown and described as four straight pieces assembled in the form of a rectangular frame to surround and support the four side edges of the rectangular light panel 41, but it is limited to this. Of course, it can have various other shapes.

And the edge frame 44 not only has the LED strip bar of the LED module 43 built in, but is also formed so that light emitted from the light emitting element (LED lamp) of the LED module 43 can be incident on the side of the light guide plate.

In addition, some edges of the light panel 41 are inserted into the grooves of the edge frame 42 and come into close contact with the LED strip bar light emitting elements constituting the LED module 43, thereby ensuring the fixed state of the LED strip bar of the LED module 43. It can be maintained.

This edge frame 42 can be formed using a processing method such as extrusion in the form of an aluminum profile to stably embed the LED module 43 and protect it from the external environment.

Here, the edge frames 42 can be integrated by arranging both ends of each end in vertical contact with each other and then welding them using a method such as friction stir welding, but using a separate corner connector 45. It is desirable to vertically connect and fix the corner portions of the edge frames 42 that come into contact with each other.

In other words, the edge frames 42 can be firmly combined into a square frame-like shape using the corner connectors 45, and the corner connectors 45 are used to place the edge frames 42 at adjacent corners. When viewed on a plane, it can be shaped like an ‘ㄱ’ shape.

Here, the corner connector 45 can be injection molded from a synthetic resin material with excellent electrical insulation properties.

In addition, of course, the edge frame 42 can be integrally formed with heat dissipation fins (not shown) that increase the contact area with air so that the heat generated by the LED module 43 can be dissipated to the outside to increase the heat dissipation effect. .

In addition, on the upper surface of the edge frame 42, the bonding strength is reinforced and bending deformation or distortion is prevented, so that the fixed state between the edge frames 42 can be maintained more firmly. In addition, parts such as a power supply unit are built in. And a separate frame (unmarked) may be attached for protection.

Meanwhile, the lighting unit 40 is configured to include an LED converter, so that AC power applied from a commercial power source is converted into DC power by the LED converter and output, and the LED module 43 is driven accordingly to emit light.

At this time, the light emitted from the LED module 43 of the lighting unit 40 may be white light emitting with a color temperature of 2,700K band (warm white series) to 6,500K band (cool white series).

A plurality of second magnets 50 are fixed on the edge frame 42 of the upper surface of the lighting unit 40 in order to attach the lighting unit 40 to the lower surface of the case 11 with magnetic force.

Here, the second magnet 50 is provided in pairs at regular intervals along the longitudinal direction of both edge frames 42 to secure convenience and stably support the lighting unit 40 when installed in the sterilizing unit 10. It is desirable.

In addition, the second magnet 50 is preferably made of a permanent magnet such as a magnetic magnet or neodymium magnet with excellent heat resistance and corrosion resistance.

And the second magnet 50 can be fixed on the edge frame 42 by tightening it with bolts or bonded with adhesive.

Meanwhile, the ceiling-type sterilizing and lighting device according to an embodiment of the present invention receives power from a separate SMPS (switched mode power supply), and operates the sterilizing unit 10 and the lighting unit 40 according to the user's on/off operation signal input. ) may include a control unit that controls them to operate individually or together.

That is, the control unit receives a manipulation signal input through the user's operation of a switch or remote controller and controls at least one of the sterilizing unit 10 and the lighting unit 40 to operate.

At this time, the control unit counts the number of consecutive on/off operations within a preset time through a calculation unit such as an MCU (Main Controller Unit), and generates a control signal to control the intensity of light emission and wavelength according to the number of operations. It can be delivered to the sterilizing unit 10 and the lighting unit 40.

In the ceiling-type sterilization and lighting device according to an embodiment of the present invention configured as described above, first, the bracket 20 is firmly fixed by driving a screw in close contact with the ceiling surface (finish surface), and then wired to the ceiling. After pulling out the existing wire and connecting a separate power supply unit, as shown in FIG. 7, the slider 35 and latch 36 fixed to the upper edge of the case 11 are attached to the bracket ( When inserted in a straight line with the guide hole 21 of the case 11, the sterilizing unit 10 is suspended from the bracket 20 due to the magnetic force of the first magnet 30 fixed to the upper edge of the case 11. It can be temporarily installed.

That is, the inner diameter of the guide hole 21 is larger than the outer diameter of the latch 36 and smaller than the outer diameter of the first magnet 30, so that the sterilizing unit 10 can naturally stick to the bracket 20 fixed to the ceiling.

In addition, the latch 36 is positioned and formed at a certain distance from the first magnet 30 to pass through the guide hole 21, so that the first magnet 30 ) and the bracket 20, so it is easy to find the position of the guide hole 21, which is hidden from view by the sterilizing unit 10 during the installation process, and can be installed simply and easily at the exact location on the ceiling by the operator alone.

In this state, as shown in FIG. 8, when the sterilizing unit 10 is pushed in the direction of the mount hole 22 of the bracket 20, the slider 35 naturally and smoothly slides along the mount hole 22. It can be installed with the latch 36 placed on the mount hole 22.

That is, as shown in FIG. 6, since the head 33 of the bolt 32 is buried below the upper surface of the first magnet 30, contact and attachment around the first magnet 30 and the mount hole 22 The area is larger than the guide hole (21), allowing a natural and stable installation state to be maintained.

In this process, as shown in FIG. 10, the catch 23 is placed in a locked state due to direct contact with the slider 35 or interference with each other. That is, the catch 23 is locked when the slider 35 is pressed in. By holding it with the friction force generated, it is possible to prevent the slider 35 from moving or being separated from the mount hole 22 by being easily separated from the mount hole 22 toward the guide hole 21 by an external force. This causes the sterilizing unit 10 to be attached to the bracket 20. ) can be maintained more firmly and stably.

Afterwards, the lighting unit 40 can be quickly and easily attached to the lower surface of the case 11 using the magnetic force of the second magnet 50.

At this time, the area of the lower surface of the case 11 is narrower than the area of the inner space formed by the skirt 44 of the lighting unit 40, that is, the upper part of the lighting unit 40 is smaller than the lower part of the case 11 due to the insertion jaw 14. It is naturally combined as if covering the surface, so the connecting parts can achieve a smooth equilibrium state without gaps or steps.

As such, the ceiling-type sterilizing and lighting device according to an embodiment of the present invention can be easily, easily, conveniently, and safely installed on the ceiling surface by a single worker or user (consumer).

In addition, unless the worker artificially manipulates the sterilizing unit 10 and pushes it out of the range of the magnetic force of the first magnet 30 or removes it, not only does it not move freely, but the sterilizing unit 10 is controlled by its own weight or external force. 1 Even if it overcomes the magnetic force (attractive force) between the magnet 30 and the bracket 20 and is separated from the bracket 20, the latch 36 is secondarily caught on the bracket 20, preventing a fall from the ceiling due to gravity. .

Meanwhile, as shown in Figure 11, the ceiling-type sterilizing and lighting device according to another embodiment of the present invention includes a wire 60 to prevent the lighting unit 40 from falling from the sterilizing unit 10 while hanging from the ceiling. It may be configured to further include.

The wire 60 has a certain length, and one end (top) in the length direction is fixed to the lower surface of the case 11, and the other end (bottom) is fixed to the upper surface of the lighting unit 40. .

That is, at least one wire 60 is installed to connect between the sterilizing unit 10 and the lighting unit 40 to prevent a falling accident of the lighting unit 40.
