[0039] The technical concept of the present utility model is further described below in conjunction with some specific implementation methods.

[0040] The utility model provides a color-changing lampshade and a lamp.

[0041] Reference Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the exploded structure of a color-changing lampshade in one embodiment of the utility model; Figure 2 It is a structural schematic diagram of the second side involved in an embodiment of the utility model.

[0042] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a color-changing lampshade includes an upper cover 100, a waterproof ring 200, a substrate 300 and a color-changing coating 400, wherein the upper cover 100 surrounds a light outlet 101; the waterproof ring 200 is arranged at intervals on one side of the upper cover 100, and the waterproof ring 200 extends along the periphery of the upper cover 100; the substrate 300 is a transparent component, and the substrate 300 has a first side surface 310 and a second side surface 320 arranged oppositely; the upper cover 100 extends along the periphery of the substrate 300, the upper cover 100 is arranged on the first side surface 310, and the upper cover 100 presses the substrate 300 on one side of the waterproof ring 200; the color-changing coating 400 is arranged corresponding to the position of the light outlet 101, and the color-changing coating 400 is coated on the second side surface 320.

[0043] It should be noted that the upper cover 100 presses the substrate 300 onto one side of the waterproof ring 200, and the color-changing coating 400 is coated on the second side 320, so that the color-changing coating 400 covers the side of the substrate 300 away from the upper cover 100, preventing the color-changing coating 400 from direct contact with the external environment, so as to ensure the service life of the color-changing coating 400; in order to ensure the light transmittance of the lampshade, the substrate 300 is a transparent PC board.

[0044] It should be understood that the color-changing coating 400 is used to present different colors, such as black, in different usage scenarios. It can be formed by an electrochromic film, thermosensitive paint or photosensitive paint in the prior art. It presents one color when there is a light source 600 and another color when there is no light source 600, so as to meet the needs of using different colors of lights for decoration or creating an environmental atmosphere in the same usage scenario.

[0045] It is worth noting that the color-changing lampshade can be applied to various lamps such as round lamps, long strip lamps, work lamps, etc.

[0046] The technical solution of the utility model is to coat a color-changing coating 400 on the substrate 300, thereby changing the light transmittance of the substrate 300 and enabling the substrate 300 to have the ability to change color. When multiple colors of lights are needed in the same usage scenario, there is no need to replace the lampshade, and the use of light sources 600 of different colors or light cups of different colors can meet the usage needs, thereby avoiding the problem of the lampshade being easily loose after assembly, and reducing the decoration cost generated by purchasing lampshades or light sources 600 of multiple colors to meet the needs of lights of different colors. When changing the color of the light, there is no need to replace the lampshades or light sources 600 of multiple colors, thereby reducing the operating process of changing the color of the light, reducing the color change time of the light, and improving the color change efficiency of the light.

[0047] In one embodiment, the color-changing coating 400 is an electrochromic film.

[0048] It should be noted that the electrochromic film is an electrochromic film in the prior art, which is a material with an electrochromic effect, and its characteristic is that it can change color under the action of an external electric field. This characteristic is caused by the rearrangement of charges inside the material, which changes the absorption spectrum of the material and thus presents different colors.

[0049] It should be understood that the electrochromic film can be formed on the substrate 300 by physical vapor deposition, sputtering, sol-gel method and other existing technologies to form the color-changing coating 400.

[0050] It is worth noting that when the color-changing coating 400 is an electrochromic film, the color-changing coating 400 is connected to an external power source through a positive lead and a negative lead.

[0051] As an optional implementation of this embodiment, when the color-changing coating 400 is not powered on, the color-changing lampshade is opaque, dark or matte, and when the color-changing coating 400 is powered on, the color-changing lampshade changes color.

[0052] Specifically, when the color-changing coating 400 is not powered, the color-changing lampshade appears black when viewed from the front. After the light is turned on and the color-changing coating 400 is powered on, the lampshade becomes transparent and the light can shine out normally. After the light is turned off and the color-changing coating 400 is powered off, the color-changing lampshade turns back to black, and the interior of the lamp body cannot be seen at a glance, so the light source 600 is "hidden" to meet the color change needs.

[0053] As another optional implementation of this embodiment, the degree of color change of the color-changing coating 400 is controlled by the size of the current: after the color-changing coating 400 is energized, the current passing into the color-changing coating 400 is adjusted to make the color of the color-changing lampshade change from dark to light or transparent.

[0054] As another optional implementation manner of this embodiment, the degree of color change of the color-changing coating 400 is controlled by the size of the current: after the color-changing coating 400 is energized, the current passed into the color-changing coating 400 is adjusted to make the color of the color-changing lampshade change from light color to dark color such as black, amber, brown and other opaque colors; after the color-changing coating 400 is powered off, the color-changing lampshade changes back to a dark color, i.e., opaque color.

[0055] As another optional implementation of this embodiment, when the color-changing coating 400 is powered on, the color-changing lampshade becomes colorless, that is, transparent; when the color-changing coating 400 is not powered on, the visual effect of the color-changing lampshade is atomized, that is, opaque.

[0056] When the color-changing coating 400 is not powered, the color-changing lampshade appears black when viewed from the front. When the light is turned on and the color-changing coating 400 is powered, the lampshade becomes transparent and the light can shine normally. When the light is turned off and the color-changing coating 400 is powered off, the color-changing lampshade turns back to black.

[0057] It is worth noting that the color of the color-changing coating 400 in the above-mentioned embodiments can be white, amber, brown or other colors or in an atomized state.

[0058] In this embodiment, an electrochromic film is used to form a color-changing coating 400. When the color-changing coating 400 is powered off, the electrochromic film presents a first color, such as opaque black; when the color-changing coating 400 is powered on, the electrochromic film presents a transparent color to meet the light color change requirements in the same usage scenario.

[0059] In one embodiment, the color-changing coating 400 is a thermosensitive color-changing layer.

[0060] It should be noted that the color-changing coating 400 is formed by spraying a thermochromic paint in the prior art. The thermochromic paint is a microcapsule pigment that repeatedly changes color as the temperature rises and falls.

[0061] It should be understood that when the color-changing coating 400 is in different temperature environments, the color-changing coating 400 can show different colors to meet the color-changing requirements of the light in the same usage scenario.

[0062] Specifically, a black material that changes color when heated is electroplated on the substrate 300 to achieve the color-changing effect.

[0063] In one embodiment, the color-changing coating 400 is a photosensitive color-changing layer.

[0064] It should be noted that the color-changing coating 400 is a photochromic dye such as ultraviolet sensitive paint in the prior art, so that the color-changing coating 400 can show different colors to meet the light color change requirements in the same usage scenario.

[0065] It should be understood that the color-changing coating 400 is formed by electroplating the photosensitive color-changing material on the substrate 300 .

[0066] Specifically, a black photosensitive color-changing material that does not absorb light is electroplated on the Lixin board, i.e., the substrate 300, so that the substrate 300 is one-way light-transmissive to achieve the color-changing effect. When the light is turned on, light can be transmitted from the substrate 300. Due to the change in the light transmission performance of the substrate 300, the PCBA is also adjusted accordingly to achieve the required performance; when the light is turned off, the substrate 300 is black, and the interior of the color-changing lampshade cannot be seen, so as to improve the decorativeness of the color-changing lampshade.

[0067] In addition, based on the same technical concept, the utility model also provides a lamp.

[0068] Continue to refer to Figure 1 and Figure 2 , and refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the exploded structure of a lamp in one embodiment of the utility model; Figure 4 It is a schematic structural diagram of the color-changing coating in one embodiment of the utility model.

[0071] It should be understood that when the color-changing coating 400 in the color-changing lampshade is the electrochromic film in the prior art, the main circuit structure of the lamp is: the circuit is composed of a control switch circuit, a signal recognition circuit, a drive circuit, a current control circuit, etc.
