Description

LED LIGHTING DEVICE WITH STERILIZATION MODULE

The present invention relates to an LED lighting device equipped with a sterilizing module, and more specifically, to an LED lighting device capable of sterilizing the air within a space in which it is installed.

As infectious diseases caused by bacteria and viruses spread, interest in indoor air quality is also increasing. In places where people are crowded, there is a possibility of infection due to viruses remaining in the air even without direct contact, so quarantine authorities are guiding that quarantine work be performed at regular intervals or that the air be circulated through continuous ventilation. However, in seasons such as spring and fall when the air is stagnant and the concentration of air pollution is particularly high, news and research results are published that heavy metals in the air can cause respiratory diseases, so there is a trend to avoid ventilation.

Due to this, the demand for air purifiers that purify indoor air and other additional devices that sterilize viruses and bacteria has been rapidly increasing recently. For example, portable or air conditioner-integrated air purifiers that are installed in indoor spaces of buildings such as homes or offices to purify the air, and devices that are attached to entrances such as shoe racks and veranda window frames to sterilize bacteria and viruses are being developed and installed.

However, places where many people enter, such as buses, campers, and mobile buildings, have spatial constraints in installing the above devices, and many of the products are installed movably rather than fixedly due to their characteristics, which requires additional installation means. To solve these problems, many products that are currently being developed with air purification or sterilization functions in addition to existing products that are essential to be installed are being developed. In particular, in the case of LED lights attached to the ceiling, more efficient placement is possible even if the size of the device is somewhat larger, so the development of related technologies is actively underway recently.

As a related prior art, Korean Patent Publication No. 10-2342478 (Air sterilization device combined with lighting) is disclosed. Korean Patent Publication No. 10-2342478 (Air sterilization device combined with lighting) is a device that can sterilize indoor air while also functioning as lighting, and is composed of a main housing, an auxiliary housing, a substrate, a cover, and titanium oxide, and the purpose of the invention is to sterilize indoor air more quickly and extensively. However, the heat dissipation and guide plate, which is a component of the prior art, is fixedly installed in a zigzag shape on the upper side of the substrate to form a sterilization path in which sterilization is performed using UV LED. However, since sufficient time is required to remove viruses and bacteria in the air using UV LED, it is difficult to secure sufficient sterilization time, and there is a problem that the entire lighting must be removed in order to install a sterilization path inside the lighting or perform maintenance and repairs. Therefore, the development of a technology to improve this is urgent.

Figure 2 is a projection drawing of an LED lighting device equipped with a sterilizing module according to the present invention in a completed assembled state.
Figure 3 is a projection diagram showing in detail the sterilizing module configuration of an LED lighting device equipped with a sterilizing module according to the present invention.

As illustrated in Figures 1 to 3 below, the LED lighting device equipped with a sterilizing module according to the present invention is an LED lighting device that is directly mounted on a ceiling and provides brightness within an installation space, and has the purpose of providing a sterilizing function that removes bacteria and viruses in the air, and is largely composed of a base housing (100), a housing cover (200), a PCB panel (300), and a sterilizing module (400).

The base housing (100) is formed so that the lower part is open, and a space is provided on the inside.

At this time, it is preferable that the space provided inside the base housing (100) be formed with sufficient width and depth to allow the PCB panel (300) and sterilization module (400) to be introduced and placed.

In addition, the base housing (100) may include a direct-mounting frame or housing for installation by being directly attached to the ceiling, or the base housing (100) itself may be attached to the ceiling so that the present invention may be installed on the ceiling of the installation space.

In addition, the base housing (100) and the direct frame may be provided with a fastening means for being connected to the ceiling or each other, and a fastening hole and fastening end into which the fastening means is inserted may be provided in the base housing (100) and/or the direct frame.

The housing cover (200) is tightly coupled to the lower surface of the base housing (100).

At this time, a penetration portion is formed in the center of the housing cover (200) into which a blower fan (210) is introduced and installed.

Additionally, a fixing member for fixing and supporting a PCB panel (300) may be formed to protrude upward on the upper surface of the housing cover (200).

The PCB panel (300) is placed on the upper side of the housing cover (200), has an inlet formed in the center through which air sucked in from a blower fan (210) passes, and an LED light source is formed on the lower surface.

At this time, the PCB panel (300) is an electronic circuit board on which electronic components such as resistors, capacitors, and integrated circuits are fixed, and a power input section (not shown) and a wiring section for an LED light source to irradiate light can be installed.

In addition, the PCB panel (300) can be inserted and fixed into a fixed end formed in the housing cover (200), and is preferably positioned at a certain distance from the inner upper surface of the housing cover (200) by being placed at the middle part of the fixed end.

The sterilization module (400) is placed on the upper surface of the PCB panel (300) and sterilizes bacteria and viruses contained in the air sucked in by the blower fan (210).

At this time, the sterilization module (400) is composed of a chamber (410), a euro-forming panel (420), and a UV LED light source (430).

The chamber (410) is a rectangular cylindrical structure that is placed on the upper surface of the PCB panel (300) and inserted into the inside of the base housing (100) when combined, and has an inlet and outlet for air sucked in by the blower fan (210).

The euro-forming panel (420) is formed on the inner upper surface of the chamber (410) to form a path for air sucked in by the blower fan (210).

At this time, the euro-forming panel (420) is formed in a fishbone shape, so that n unit sterilization sections (n is a natural number) can be formed in the air flow path flowing along the periphery.

In addition, it is preferable to separately provide a fixing means for fixing the euro-forming panel (420) to the inner upper surface of the chamber (410), i.e., the ceiling surface.

And, this euro-forming panel (420) can be composed of a partition (421), a main partition (422), and a branch partition (423).

The partition (421) is arranged vertically in the front-back direction inside the chamber (410) to partition the internal space of the chamber (410) into left and right sides so that air sucked in by the blower fan (210) flows in to the left and right sides.

In addition, the partition (421) can be formed by dividing it into a horizontal portion attached to the inner upper surface of the chamber (410) and a vertical portion that partitions the inner space of the chamber (410).

At this time, as shown in FIGS. 1 and 2, the partition (421) may be formed with a gently curved surface in the horizontal and vertical portions so that the intake air is supplied to the interior.

And, the main unit (422) and the branch unit (423) are formed in a fishbone diagram shape.

The main unit (422) is a rectangular panel and is arranged vertically in the left and right directions so as to intersect with the partition unit (421).

The branches (423) are connected in a '<' shape with symmetry or staggered asymmetrical angles in the front and rear with the main branch (422) as the center, and are arranged vertically on the inner upper surface of the chamber (410).

At this time, the branch (423) is formed integrally with the main branch (422) or is formed detachably so that the air flow can be variably adjusted.

In addition, the branches (423) can each be equipped with a UV LED light source on the wall, and can provide ultraviolet light that can remove bacteria and viruses in the air when air sucked in through the blower fan (210) passes through the internal space of the chamber (410).

At this time, the UV LED light source equipped on the branch (423) has a deep ultraviolet wavelength range of 100 to 280 nm, so ultraviolet sterilization can be performed.

In addition, the air passing through the euro-forming panel (420) by the branch (423) forms a vortex, so that the air stays near the branch (423) for a certain period of time, and accordingly, the time for which the UV LED light source irradiates ultraviolet light to the air increases, enabling more effective sterilization.

Additionally, the branch (423) may be configured to include an auxiliary air passage (not shown).

An auxiliary air passage may be formed on the lower side of the branch (423) and may serve as a passage through which the intake air passes.

That is, when the auxiliary air passage (423) is placed on the main section (422), it can be formed by penetrating the inner bottom, and the main section (422) and the auxiliary air passage can form a bulkhead, thereby providing a passage through which the sucked air passes.

In addition, the sterilization module (400) may be configured to include a coupling means for coupling to a PCB panel (300) on the lower surface of the chamber (410).

At this time, the connecting means may be composed of a bolt fastening member and a bolt, and it is preferable that corresponding bolt connecting holes are formed on both sides of the chamber (410) and the PCB panel (300).

For example, a plurality of flat-shaped fastening protrusions may be formed in an outward direction on the lower surface of the chamber (410), and a bolt-joining hole may be provided in each fastening protrusion.

Looking at an example of an LED lighting device equipped with a sterilizing module according to the present invention through the above configuration, as shown in (a) and (b) of FIGS. 1 and 2, the assembly can be completed by sequentially combining a PCB panel (300) and a sterilizing module (400) on a housing cover (200) and combining them with a base housing (100) that is directly attached to the ceiling and fixed.

And, when power is supplied and the blower fan (210) is operated, air in the internal space where the LED lighting device equipped with the sterilization module of the present invention is installed is sucked in, passes through the housing cover (200) and the PCB panel (300), is supplied to the inlet of the chamber (410), and flows into the left and right spaces along the partition (421).

Air flowing into the chamber (410) passes through the vortex-forming panel (420), and passes through the unit sterilization section formed by the main unit (422) and the branch unit (423), where the UV LED light source removes bacteria and viruses in the moving air.

And, the sterilized air passing through the euro-forming panel (420) is discharged to the outside through the outlet of the chamber (410).

In addition, the sterilizing module (400) of the LED lighting device equipped with the sterilizing module of the present invention is configured to include a negative ion generating chip and can purify the air inside.

In addition, the LED lighting device equipped with the sterilizing module of the present invention can be configured to include a mesh filter (411) and an air exhaust fan (412).

A mesh filter (411) is placed at the outlet of the chamber (410) to filter dust in the air.

At this time, a filter fixing member for fixing the mesh filter (411) may be provided inside the chamber (410), and it is preferable that the mesh filter (411) be formed so as to be detachable from the filter fixing member.

The air exhaust fan (412) is placed adjacent to the mesh filter (411) and discharges the sterilized air to the outside while passing through the filtration panel (420).

At this time, a fan fixing member for fixing the air exhaust fan (412) may be provided inside the chamber (410), and it is preferable that the air exhaust fan (412) be formed so as to be detachable from the fan fixing member.
