In the following description, the configuration of the ultraviolet light encapsulation structure 105 will be described in detail.

FIG. 3 shows a cross-sectional view of the ultraviolet encapsulation structure 105 of FIG. 2 along the line 3-3. The ultraviolet encapsulation structure 105 includes a support base 110, an ultraviolet short-wave light emitting diode 120 (UVC LED), and a low-temperature deposition layer 130. The support base 110 has a top surface 111 and a bottom surface 115 opposite to each other, and the support base 110 has a groove 112 therein. The groove 112 is on the side of the support base 110 close to the top surface 111. The short-wave ultraviolet light emitting diode 120 is located in the groove 112 of the support base 110. In this embodiment, the short-wave ultraviolet light emitting diode 120 is a flip chip light emitting diode. In other embodiments, the ultraviolet encapsulation structure 105 can also be replaced by a short-wave ultraviolet light-emitting diode bonded by wire bonding, which is not intended to limit the present invention.

The low temperature deposition layer 130 covers the ultraviolet short-wave light emitting diode 120, and the low temperature deposition layer 130 is an inorganic layer. Generally speaking, ultraviolet light emitting diodes will accelerate the oxidation of organic materials due to ultraviolet light radiation, thus causing light attenuation problems. However, the low-temperature deposition layer 130 of the present invention is an inorganic layer, which can be formed by metal organic chemical vapor deposition (MOCVD) or atomic layer deposition (ALD) below 200°C. , Can effectively avoid the light attenuation caused by organic materials. In this embodiment, the low-temperature deposition layer 130 may be an aluminum nitride (AlN) layer or an aluminum oxide (Al ₂ O ₃ ) layer, but it is not limited to this. The top surface 132 of the low-temperature deposition layer 130 is flat. The low-temperature deposition layer 130 has light penetration, corrosion resistance, and optical properties, and can effectively block moisture and dust. The low-temperature deposition layer 130 can be used as a protective layer for the ultraviolet shortwave light-emitting diode 120, and the traditional glass cover plate surrounded by the support base 110 can be omitted, thereby reducing the height of the support base 110, avoiding shading, and benefiting the overall ultraviolet light packaging structure The miniaturized design of 105 can save material cost.

In addition, no additional gas (such as nitrogen or argon) needs to be filled between the low-temperature deposition layer 130 of the ultraviolet encapsulation structure 105 and the ultraviolet short-wave light emitting diode 120, which can save the process cost of assembling the ultraviolet encapsulation structure 105. When the low-temperature deposition layer 130 is formed by the MOCVD method, its thickness may be 150-1000 atoms in thickness; when the low-temperature deposition layer 130 is formed by the ALD method, its thickness may be 1-10 atoms in the thickness. In addition, in this embodiment, the groove 112 of the support base 110 has a groove bottom 113 and a side wall 114, and the side wall 114 surrounds the groove bottom 113. The ultraviolet short-wave light emitting diode 120 is located on the bottom 113 of the groove 112, and the low-temperature deposition layer 130 directly contacts the sidewall 114 of the groove 112.

The bottom surface 125 of the ultraviolet shortwave light emitting diode 120 has an electrode 126, the bottom surface 115 of the support base 110 has an electrode 116, and the electrode 126 of the ultraviolet shortwave light emitting diode 120 is electrically connected to the electrode 116 of the support base 110. For example, the electrode 126 of the ultraviolet short-wavelength light-emitting diode 120 can be electrically connected to the electrode 116 of the support base 110 via a conductor 117. In addition, the electrode 116 can be further electrically connected to a power source controlled by the controller 170 to turn on or off the ultraviolet short-wave light emitting diode 120.

It should be understood that the connection relationships, materials, and effects of the components that have been described will not be repeated, and will be described first. In the following description, other forms of UV light packaging structures will be described.

FIG. 4 is a cross-sectional view of an ultraviolet light encapsulation structure 105a according to another embodiment of the present invention. The ultraviolet light packaging structure 105a includes a support base 110, a short-wave ultraviolet light emitting diode 120, and a low temperature deposition layer 130. The difference from the embodiment in FIG. 3 is that the top surface 132a of the low-temperature deposition layer 130 protrudes away from the ultraviolet short-wavelength light-emitting diode 120. The method for forming the arc-shaped top surface 132a of the low-temperature deposition layer 130 may include depositing an inorganic layer in the groove 112 of the support base 110 and covering the ultraviolet short-wave light emitting diode 120, and then forming a grayscale mask on the inorganic layer. Then, the inorganic layer is etched by reactive ion etching (RIE) method and acid gas. Since the gray-scale photomask can have a depth gradient photosensitive ability, the shape of the underlying inorganic layer can be changed through the etching step, and the low-temperature deposition layer 130 with the curved top surface 132a in Figure 4 can be obtained. In other words, the forming method of the low-temperature deposition layer 130 is a lens structure that is chemically or physically etched to achieve the target shape after the deposition is completed.

In this embodiment, the thickness H1 of the low-temperature deposition layer 130 of the ultraviolet light encapsulation structure 105a may be at least 1.5 times the thickness H2 of the ultraviolet shortwave light emitting diode 120 to have sufficient protection and blocking effects, such as shortwave ultraviolet light. When the thickness H2 of the light emitting diode 120 is 250 μm, the thickness H1 of the low-temperature deposition layer 130 is greater than 375 μm. For example, the thickness H1 of the low-temperature deposition layer 130 may be in the range of about 1 mm to 4 mm.

In this embodiment, the vertex P of the top surface 132 of the low-temperature deposition layer 130 may be substantially flush with the top surface 111 of the support base 110, but it is not used to limit the present invention.

It should be understood that the connection relationships, materials, and effects of the components that have been described will not be repeated, and will be described first. In the following description, the operation state of the ultraviolet light disinfection assembly 100 shown in Figs. 1 and 2 will be described.

FIG. 5 shows a flow chart of the ultraviolet light disinfection assembly 100 in FIG. 1 during operation. Referring to Fig. 1, Fig. 2 and Fig. 5 at the same time, first, in step S1, the ultraviolet light disinfection assembly 100 is activated. Then in step S2, the controller 170 can determine whether someone has used the elevator 200 based on the detection information of the biosensor 160 in the past time. If it is determined that someone has used the elevator 200, the process proceeds to step S3, and the controller 170 can determine through the biosensor 160 whether someone is currently in the elevator 200. If it is determined that no one is currently in the elevator 200, then step S4 is entered, and the controller 170 can activate the moving part 150 and the ultraviolet light packaging structure 105. For example, the moving element 150 can move to the key area 210 (that is, move to the direction D1).

FIG. 6 is a perspective view of the moving part 150 of FIG. 1 when it passes in front of the key area 210. FIG. 7 is a perspective view of the moving member 150 of FIG. 6 after it continues to move downward and leaves the key area 210. Referring to Fig. 5, Fig. 6 and Fig. 7 at the same time, when the moving part 150 moves in the direction D1, the moving part 150 can pass in front of the key area 210. As a result, the ultraviolet light emitted by the ultraviolet light encapsulation structure 105 can be Scan the key area 210 to sterilize the entire key area 210, as shown in step S5 in FIG. 5. The part to be moved 150 will be located below the key area 210 after passing through the key area 210. Then, proceed to step S6, and the movable member 150 can move in the direction D2 to return to the origin (as shown in Figure 1). In this step, the ultraviolet light encapsulation structure 105 can be in the closed state without re-sterilization or in the open state, depending on the design requirements. Then enter step S7, after the moving part 150 returns to the position of FIG. 1, the ultraviolet light disinfection assembly 100 can be in a standby state. In step S8, the biosensor 160 can detect at a fixed time to determine whether someone has used the elevator 200, and then return to step S2.

In addition, in step S2, if the controller 170 determines that no one has used the elevator 200 through the detection information of the biosensor 160, the ultraviolet light disinfection assembly 100 can directly enter the standby state of step S7 to avoid contacting the unpressed The key area 210 is sterilized again, which can save power and prolong the service life of the ultraviolet disinfection assembly 100.

In addition, in step S3, if the controller 170 determines that someone is currently in the elevator 200 via the biosensor 160, the ultraviolet light disinfection assembly 100 can directly enter the standby state in step S7 to avoid harm to the human body in the elevator 200.
