FIELD OF THE DISCLOSURE
The present disclosure is related to a technical filed of air sterilization and disinfection, and more particularly to a UVC-integrated LED structure that is equipped with grilles used for air sterilization and disinfection.
BACKGROUND OF THE DISCLOSURE
An air purifier, which is also known as an air cleaner, an air purifier or a purifier, indicates a product that is able to absorb, decompose or transform various air pollutants can effectively improve air cleanliness. The air purifier includes different technologies and mediators that are used to provide clean and safe air for users. The general technologies used in the air purifier are such as technologies relating to adsorption, negative and positive ions, catalysis, photocatalyst, superstructured light mineralization, HEPA high-efficiency filtration, and/or electrostatic dust precipitation.
A UVC (ultraviolet ray in “C” spectrum) integrated LED module is one of the important and requisite components in the air purifier. The UVC-integrated LED module includes a PCB substrate, multiple wavy grilles and a COB (chip on board) light board. However, in the conventional technology, general COB light boards are engaged with troughs of the wavy grilles and resulting in bumped areas. When air passes between the wavy grilles, the dust may be accumulated on the COB light boards easily and the accumulated dust may affect energy output of ultraviolet ray.

In an aspect of the present disclosure, COB light boards are disposed inside placement grooves that are openly disposed on troughs of the wavy grilles. The COB light boards can therefore be hidden on the surfaces of the wavy grilles as much as possible. Therefore, the height of COB can be decreased. The structure can reduce air resistance when the ultraviolet ray irradiates on the passing air. Further, impact of dust being adhered to the COB light boards on energy output of the ultraviolet ray can be reduced.
For implementing the above technical purpose, a UVC-integrated LED structure adapted to air sterilization-and-disinfection grilles is provided. The UVC-integrated LED structure includes a housing, an opening openly disposed on a top of the housing, multiple wavy grilles engaged with two sides of inner wall of the opening, placement grooves openly disposed on one side of the wavy grilles, and multiple COB light boards disposed inside the placement grooves.
Further, the wavy grille can be in a tile shape.
Still further, a grille passage is openly disposed between every two adjacent wavy grilles.
Further, a plurality of grille passages are separated by the multiple wavy grilles and the multiple wavy grilles are arranged uniformly.
Still further, the both sides of inner wall of the opening are mounted with a PCB substrate, and the two ends of the COB light boards are engaged to the PCB substrate respectively.
Further, multiple lamp beads are disposed on one side of the COB light board.
These and other aspects of the present disclosure will become apparent from the following description of the embodiment taken in conjunction with the following drawings and their captions, although variations and modifications therein may be affected without departing from the spirit and scope of the novel concepts of the disclosure.

The UVC-integrated LED structure that is adapted to air sterilization-and-disinfection grilles. The UVC-integrated LED structure provides following beneficial effects.
The structure of the present disclosure provides following beneficial effects. COB light boards are mounted on placement grooves that are openly disposed on the troughs of wavy grilles. The structure allows the COB light boards to be hidden on the surfaces of the wavy grilles as much as possible. Since the height of COB can be decreased, the air resistance can be reduced when the ultraviolet ray irradiates on the passing air. The impact of dust being adhered to the COB light boards on energy output of the ultraviolet ray can be reduced.
Therefore, the air passing through the multiple wavy grilles can be sterilized and disinfected since the multiple wavy grilles are disposed at the opening of the housing.
Embodiments
References are made to FIGS. 1 to 6. A UVC-integrated LED structure that is adapted to air sterilization-and-disinfection grilles is provided. The UVC-integrated LED structure includes a housing 1, multiple wavy grilles 102 that are openly disposed on an opening 101 at the top of the housing 1, and the wavy grilles 102 engaged with both sides of inner wall of the opening 101 form multiple grille passages 3. The grille passages 3 allow the UVC-integrated LED structure to irradiate ultraviolet ray for air sterilization. A COB light board 2 can be mounted on placement grooves 103 that are openly disposed at one side of the wavy grilles 102. The COB light boards 2 disposed inside the placement grooves 103 irradiate ultraviolet ray for air disinfection.
Further, the wavy grille 102 can be in a tile shape that can be disposed in the placement groove 103 through the COB light board 2. Therefore, the COB light boards 2 disposed at troughs of the wavy grilles 102 can be hidden on the surface of the wavy grilles 102 as much as possible. Further, the height of the COB light boards 2 disposed inside the placement grooves 103 can be effectively reduced. The COB light boards 103 form parts of the surfaces of the wavy grilles 102, and air resistance can be reduced when the ultraviolet ray irradiates on the passing air. Since the air resistance is small, the impact of dust being adhered to the COB light boards 2 on energy output of the ultraviolet ray can be reduced. The output of the ultraviolet ray can therefore be guaranteed.
Further, a grille passage 3 is openly disposed between two adjacent wavy grilles 102. When a device having the UVC-integrated LED structure is in operation, the air can pass through the grille passage 3.
Further, the plurality of grille passages 3 are separated by the multiple wavy grilles 102, and the multiple wavy grilles 102 are arranged uniformly. The grille passages 3 with a uniform diameter allow the air flow passing the grille passages 3 to be consistent. The effect of air disinfection and sterilization can be guaranteed.
Still further, both sides of inner wall of the opening 101 are mounted with the PCB substrate 4, and the two ends of the COB light boards 2 are engaged with the PCB substrate 4. The PCB substrate 4 can supply power to the COB light boards 103 when the device is in operation.
Further, there are multiple lamp beads disposed on one side of the COB light board 2. When the COB light board 2 is in use, the lamp beads irradiate ultraviolet rays and the air passing the grille passages 3 can be disinfected and sterilized.
In the embodiments, the description with respect to each of the embodiments has its own emphasis, and parts of some of the embodiments that lack details can refer to the descriptions of other embodiments.
In conclusion, the above embodiments provide detailed descriptions relating to the UVC-integrated LED structure that is able to conduct air sterilization and disinfection. Through the UVC-integrated LED structure, the air passing through the multiple wavy grilles can be sterilized and disinfected.
