[0002] LED panel lights are common indoor lighting fixtures in modern society. Their outer frames are made of aluminum alloy and other materials. They use LED as light sources and are usually installed by adsorbing them on the ceiling and flush with the ceiling. They can bring good lighting effects without affecting the appearance. As various harmful microorganisms exist in people's living environment, which will affect the health of residents, with the popularization of ultraviolet sterilization, some panel lights with ultraviolet sterilization function are gradually launched on the market.

[0003] In the prior art, UV LED lamp beads are usually added to some conventional lamps, combined with sensors and control systems to achieve human-machine coexistence of UV sterilization-lighting lamps. However, since this type of lighting fixture usually irradiates the UV sterilization module directly downward, if it is defined as a UV sterilizer, the general practice is to use sensors to identify organisms and control the lighting and UV sterilization to work separately, which cannot achieve the most efficient human-machine coexistence; if it is defined as a general lighting fixture, in order to pass the standard of "GBT 20145-2006 Photobiological Safety of Lamps and Lamp Systems", the radiation intensity of its UV sterilization module must be very small, so the effect is also minimal, and it is difficult to ensure that all products can meet the standards. Once the standard is exceeded, it will cause serious harm to the human body when used.

[0030] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] like Figure 1 As shown, an embodiment of the utility model provides a frame with a sterilization function, including a main frame 100 and a sterilization component; wherein, a mounting groove is provided on the inner side of the main frame 100, and a sterilization light output groove 110 is provided on the outer side, and the mounting groove and the sterilization light output groove 110 are connected through a light output channel 120, and the length direction of the light output channel 120 extends horizontally, and part of the main frame 100 around the light output channel 120 is made of non-light-transmitting material; the sterilization component is installed in the mounting groove, and the sterilization component is opposite to the sterilization light output groove 110.

[0032] In some embodiments of the present invention, the frame with sterilization function also includes an insulating layer 130, which is arranged on the side of the light output channel 120 close to the sterilization light output groove 110. The insulating layer 130 can be any one of quartz glass, sapphire, and magnesium-fluorine aluminum glass, preferably highly ultraviolet-transmittance quartz glass, which is used to isolate external dust and water vapor from entering through the light output channel 120, thereby affecting the sterilization effect of the sterilization component.

[0033] In some embodiments of the utility model, the sterilization component includes a UVC-LED lamp board 210 and a UVC-LED lamp bead 220; the UVC-LED lamp board 210 is fixed in the installation groove. Specifically, the UVC-LED lamp board 210 can be installed by high-temperature resistant glue or threaded connection or interference fit. It can be installed according to actual conditions and there is no special limitation on this.

[0034] The UVC-LED lamp bead 220 is electrically connected to the UVC-LED lamp board 210. Specifically, the UVC-LED lamp bead 220 is fixed on the UVC-LED lamp board 210, and the UVC-LED lamp bead 220 is directly opposite to the sterilizing light emitting groove 110, so as to emit sterilizing light to the indoor space through the light emitting channel 120 and the sterilizing light emitting groove 110.

[0035] In some embodiments of the present invention, a reflective coating is disposed on the inner wall of the light exit channel 120 , and the ratio of the width to the height of the light exit channel 120 is greater than or equal to 1.5.

[0036] When it is necessary to achieve higher light efficacy at lower power, that is, to achieve higher sterilization rate at low power, it is necessary to coat the inner wall of the light outlet channel 120 with a reflective coating or set with anti-ultraviolet light materials such as aluminum foil and Teflon. Since the light output of UVC-LED has a certain angle, such a setting can make the light from the upper and lower sides be reflected and emitted in the sterilization light outlet groove 110, thereby achieving higher light utilization. However, in this case, some light will leak downward, so it is preferred that the width:height of the light outlet channel 120 is greater than or equal to 1.5:1 and the intensity of the UVC-LED light source is 72μw / cm 2 To meet national standards.

[0037] In some embodiments of the present invention, a light absorbing material is disposed on the inner wall of the light exit channel 120 , and the ratio of the width to the height of the light exit channel 120 is greater than or equal to 1.5.

[0038] When there are higher safety standards and higher sterilization rate requirements, higher power UVC-LED lamp beads 220 need to be used, and it is necessary to ensure that the ultraviolet light emitted from the sterilization light output groove 110 is emitted straight. At this time, the inner wall of the light output channel 120 is coated with light-absorbing material so that the radial light is absorbed in the light output channel 120 without the risk of downward leakage.

[0039] In other embodiments of the present invention, a lamp is provided, which also includes a main frame 100, a lampshade, a lighting assembly 300 and a power supply 400, wherein the main frame 100 is the same as any of the above embodiments and will not be described in detail herein.

[0040] In other embodiments of the present invention, the lampshade is connected to the main frame 100; the lighting assembly 300 is connected to the main frame 100 and / or is arranged on the inside of the lampshade; the power supply 400 is electrically connected to the lighting assembly 300 and the sterilization assembly, and the lighting assembly 300 is preferably a lighting LED lamp board.

[0041] Specifically, when the lampshade is a front-emitting panel lamp, the lighting LED is arranged inside the lampshade, and when the lampshade is a side-emitting panel lamp, the lighting LED is arranged on the main frame 100, and a light guide plate and a reflector are required, which are all conventional arrangements.

[0042] In some other embodiments of the present invention, the lampshade includes a rear cover 500 and a light diffuser 600; wherein the rear cover 500 is connected to the main frame 100, and a flange 510 extends outward from the side of the rear cover 500, and the flange 510 abuts against the UVC-LED lamp board 210 and the light diffuser 600 respectively;

[0043] The light diffusion plate 600 is disposed on the light irradiation surface of the lighting assembly 300 , and the light diffusion plate 600 is fixed to the top of the main frame 100 through the rear cover 500 .

[0044] Specifically, the light diffuser plate 600 is arranged on the light irradiation surface of the lamp. When the back cover 500 is installed on the main frame 100, the bottom of the flange 510 abuts against the light diffuser plate 600 to fix the light diffuser plate 600 on the main frame 100; further, since the UVC-LED lamp board 210 is fixed with the mounting groove, the side of the flange 510 also abuts against the UVC-LED lamp board 210 to form an interference fit, so that the UVC-LED lamp board 210 can be further reinforced, and the heat of the UVC-LED lamp board 210 can be dissipated through the back cover 500.

[0045] The lamp structure of the utility model can facilitate the installation and disassembly of the UVC-LED lamp board 210, and the UVC-LED lamp board 210 has better heat dissipation performance.

[0046] In other embodiments of the utility model, the main frame 100 and the back cover 500 are aluminum profiles with a certain amount of deformation, so the wires of the UVC-LED light board 210 can directly pass through the connection between the flange 510 of the back cover 500 and the light diffuser plate 600, and are connected to the power supply 400 together with the lighting assembly 300, and are driven and controlled by the power supply 400; a wire outlet hole is provided on the back of the back cover 500, and the lighting LED light board and the UVC-LED light board 210 are both connected to the power supply 400 through the wire outlet hole.

[0047] In summary, the utility model includes a lamp with a sterilization function frame, which can efficiently achieve effective antibacterial effect on the air while humans and machines coexist without additional sensors, and is completely harmless to living organisms; the setting of two different coatings on the light output channel can meet different sterilization efficiency requirements, and the connection structure of the back cover, the light diffuser plate and the main frame makes the UVC-LED lamp board have good heat dissipation performance.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
