DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.

[0025] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the utility model.

[0026] See also Figure 1 The present invention provides a lamp 10 having an illumination function. The lamp 10 can also project a specific pattern from its light spot. The lamp 10 includes a light source module 30 and a projection film 20. The light source module 30 is configured to generate output light. The projection film 20 is positioned in the optical path of the output light from the light source module 30, thereby allowing the light spot of the lamp 10 to display the pattern of the projection film 20.

[0027] There are many options for the light source module 30 . For example, the light source module 30 may be an LED lamp; for another example, the light source module 30 may be a laser; or for another example, the light source module 30 may be a fluorescent lamp.

[0028] The specific structure of the slide 20 can refer to the following embodiments. Since the lamp 10 adopts all technical solutions of all the following embodiments, it has at least all the beneficial effects brought by the technical solutions of the following embodiments, which will not be described in detail here.

[0029] See also Figure 2 and Figure 3 An embodiment of the present invention provides a projection film 20, which may include a film substrate 100, a coated glass substrate 200, and a projection pattern layer 260, wherein the coated glass substrate 200 may be stacked with the film substrate 100, and the projection pattern layer 260 includes an inorganic pigment coating 210 and an organic pigment coating 110, and the projection pattern layer 260 has a first projection area 261 and a second projection area 263, the organic pigment coating 110 is provided on the film substrate 100 and is located in the first projection area 261, and the inorganic pigment coating 210 is provided on the coated glass substrate 200 and is located in the second projection area 263. Thus, compared to the projection films in the related art, the second projection area 263 of the projection pattern layer 260 of the projection film 20 of the present application is formed by the inorganic pigment coating 210. The inorganic pigment coating 210 has good stability. Therefore, the inorganic pigment coating 210 of the projection pattern layer 260 is less affected by strong light and high temperature environments and is not easy to fade, thereby helping to extend the service life of the projection film 20.

[0030] In addition, since the first projection area 261 of the projection pattern layer 260 is formed by the organic pigment coating 110, the organic pigment coating 110 has the characteristic of rich colors, so that the projection film 20 can retain the characteristics of the film, which helps the projection film 20 have higher resolution and rich colors.

[0031] In some embodiments, the projection of the first projection area 261 and the projection of the second projection area 263 do not overlap on the projection plane (the projection plane may be the receiving surface of the light emitted by the lamp 10). In this way, the projection pattern layer 260 can be divided into the first projection area 261 and the second projection area 263, so that the projection sheet 20 can display patterns with different characteristics on the same projection plane.

[0032] Furthermore, the projection of the first projection area 261 and the projection of the second projection area 263 do not overlap on the projection plane. When the projection film 20 is projected, the pattern formed by the inorganic pigment coating 210 and the pattern formed by the organic pigment coating 110 do not overlap, ensuring the clarity and independence of the pattern on the projection film 20. Furthermore, the light emitted by the light source module 30 does not need to pass through both the inorganic pigment coating 210 and the organic pigment coating 110 simultaneously, thus avoiding the risk of color mixing caused by overlapping pigment layers in the projected pattern of the lamp 10.

[0033] In some embodiments, the organic pigment coating 110 has a first notch region 262, which is adjacent to the first projection region 261 and overlaps with the second projection region 263. The first notch region 262 may be an area that is shielded by a mask or the like during the manufacturing process of the organic pigment coating 110 and in which no organic pigment is formed. The first notch region 262 and the organic pigment coating 110 are located in the same plane. This helps ensure that the projection of the first projection region 261 and the projection of the second projection region 263 do not overlap on the projection plane, so that the emitted light from the light source module 30 does not need to pass through the first projection region 261 and the second projection region 263 simultaneously, thereby avoiding the risk of color mixing caused by the overlapping pigment layers in the projection pattern of the lamp 10.

[0034] In some embodiments, the film substrate 100 has a second notch region (not shown), which is adjacent to the first projection region 262 and overlaps with the second projection region 263. The second notch region can be formed by removing a portion of the film substrate 100, resulting in a notch in the film substrate 100. The second notch region and the organic pigment coating 110 are located in different planes, while the second notch region and the film substrate 100 are located in the same plane. This helps ensure that the projections of the first projection region 261 and the second projection region 263 do not overlap on the projection plane, so that the emitted light from the light source module 30 does not need to pass through the first projection region 261 and the second projection region 263 at the same time, thereby avoiding the risk of color mixing caused by the overlapping pigment layers in the projection pattern of the lamp 10.

[0035] In some embodiments, the film substrate 100 is further provided with an exposure coating (not shown), which is adjacent to the first projection area 261 and overlaps with the second projection area 263. The exposure coating can be in the same plane as the organic pigment coating 110. During the manufacturing process of the exposure coating, the exposure coating can be formed by irradiating the organic pigment coating 110 with white light, so that the exposure coating becomes a transparent coating. This helps to achieve that the projection of the first projection area 261 and the projection of the second projection area 263 do not overlap on the projection plane, so that the emitted light of the light source module 30 does not need to pass through the first projection area 261 and the second projection area 263 at the same time, avoiding the risk of color mixing caused by the superposition of pigment layers in the projection pattern of the lamp 10.

[0036] In some embodiments, the color of the organic pigment coating 110 is different from the color of the inorganic pigment plating layer 210. By placing the easily faded color of the organic pigment coating 110 on the inorganic pigment plating layer 210, the fading speed of the organic pigment coating 110 can be effectively reduced, thereby extending the life of the transparencies 20 in environments with strong light and high temperatures.

[0037] In addition, the slide film 20 has both the inorganic pigment coating 210 and the organic pigment coating 110 , so that the slide film 20 can have the rich color characteristics of the organic pigment coating 110 and the stability characteristics of the inorganic pigment coating 210 .

[0038] The yellow organic pigment coating 110 , the green organic pigment coating 110 and the cyan inorganic pigment coating 210 are easily faded under strong light and high temperature environments, thereby reducing the service life of the slide.

[0039] In view of this, in some embodiments, the color of the inorganic pigment coating 210 includes at least one of yellow, green, or cyan, and the color of the organic pigment coating 110 is different from the color of the inorganic pigment coating 210. For example, the color of the inorganic pigment coating 210 may include yellow; for another example, the color of the inorganic pigment coating 210 may include green; for another example, the color of the inorganic pigment coating 210 may include cyan; for another example, the color of the inorganic pigment coating 210 may include yellow and green; for another example, the color of the inorganic pigment coating 210 may include green and cyan; for another example, the color of the inorganic pigment coating 210 may include yellow and cyan; for another example, the color of the inorganic pigment coating 210 may include yellow, green, and cyan. Placing the easily faded color (e.g., yellow, green, or cyan) of the organic pigment coating 110 on the inorganic pigment coating 210 can effectively reduce the fading speed of the organic pigment coating 110, thereby extending the life of the projection film 20 under strong light and high temperature environments.

[0040] In some embodiments, the organic pigment coating 110 may be located on the side of the film substrate 100 facing the coated glass substrate 200. Thus, the organic pigment coating 110 is located between the film substrate 100 and the coated glass substrate 200, which helps reduce the risk of the organic pigment coating 110 of the projection film 20 being scratched or impacted during assembly and transportation, thereby helping to protect the organic pigment coating 110.

[0041] In addition, the film substrate 100 and the coated glass substrate 200 can jointly form a closed protective layer, which helps reduce the risk of the organic pigment coating 110 coming into contact with moisture or other corrosive substances in the environment, thereby helping to reduce the risk of the organic pigment coating 110 being affected by moisture or chemical corrosion, and further helping to extend the service life of the slide 20.

[0042] In some embodiments, the inorganic pigment coating 210 can be located on the side of the coated glass substrate 200 facing the film substrate 100, so that the inorganic pigment coating 210 is located between the film substrate 100 and the coated glass substrate 200, which helps to reduce the risk of the inorganic pigment coating 210 of the slide 20 being scratched or collided during assembly and transportation, thereby helping to protect the inorganic pigment coating 210.

[0043] In addition, the film substrate 100 and the coated glass substrate 200 can jointly form a closed protective layer, which helps reduce the risk of the inorganic pigment coating 210 coming into contact with moisture or other corrosive substances in the environment, thereby helping to reduce the risk of the inorganic pigment coating 210 being affected by moisture or chemical corrosion, and further helping to extend the service life of the slide 20.

[0044] In some embodiments, the coated glass substrate 200 can be made of transparent glass. The film substrate 100 and the coated glass substrate 200 can be arranged in a sheet form, and the coated glass substrate 200 can be stacked with the film substrate 100, thereby helping the coated glass substrate 200 support the film substrate 100. Furthermore, the film substrate 100 can be bonded to the coated glass substrate 200, thereby reducing the risk of bending of the film substrate 100 and blurring the projection pattern of the lamp 10.

[0045] In some embodiments, the slide 20 may further include a first adhesive layer 300 . The first adhesive layer 300 may be used to bond the film substrate 100 and the coated glass substrate 200 . The first adhesive layer 300 may be silicone thermal conductive adhesive or epoxy resin thermal conductive adhesive.

[0046] The film substrate 100, first adhesive layer 300, and coated glass substrate 200 are stacked in sequence, with the inorganic pigment coating 210 and organic pigment coating 110 located on opposite sides of the first adhesive layer 300. This helps prevent environmental substances (such as moisture and oxygen) from chemically reacting with the organic pigment coating 110 and inorganic pigment coating 210, thereby slowing the fading of the organic pigment coating 110 and protecting the inorganic pigment coating 210.

[0047] In addition, the first adhesive layer 300 can bond the film substrate 100 and the coated glass substrate 200 , which helps to improve the stability of the interlayer structure between the film substrate 100 and the coated glass substrate 200 .

[0048] In some embodiments, the thermal conductivity of the first adhesive layer 300 and the thermal conductivity of the coated glass substrate 200 can be greater than the thermal conductivity of the film substrate 100, so that the organic pigment coating 110 can quickly transfer heat to the first adhesive layer 300 and the coated glass substrate 200, thereby helping to reduce the impact of heat on the organic pigment coating 110.

[0049] See also Figure 4 and Figure 5 In some embodiments, the slide 20 further includes a protective glass substrate 400 and a second adhesive layer 500. The second adhesive layer 500 can be made of transparent glue, and the protective glass substrate 400 can be made of transparent glass. The protective glass substrate 400 can be bonded to the film substrate 100 via the second adhesive layer 500.

[0050] The coated glass substrate 200, film substrate 100, second adhesive layer 500, and protective glass substrate 400 are stacked in sequence. The film substrate 100 is sandwiched between the protective glass substrate 400 and the coated glass substrate 200, allowing the protective glass substrate 400 and the coated glass substrate 200 to protect the film substrate 100. This helps the protective glass substrate 400 and the coated glass substrate 200 protect the film substrate 100 from scratches, impacts, and other physical damage, thereby helping to protect the film substrate 100.

[0051] In addition, since the film substrate 100 is sandwiched between the protective glass substrate 400 and the coated glass substrate 200 , the protective glass substrate 400 and the coated glass substrate 200 have good strength, thereby helping to improve the mechanical strength of the projection film 20 .

[0052] In some embodiments, the thermal conductivity of the protective glass substrate 400 and the second adhesive layer 500 are both greater than that of the film substrate 100. The second adhesive layer 500 can be a silicone or epoxy thermally conductive adhesive, and the protective glass substrate 400 can be quartz glass. This allows the film substrate 100 to quickly transfer heat to the protective glass substrate 400 and the second adhesive layer 500, thereby reducing the impact of heat on the organic pigment coating 110.

[0053] In some embodiments, the inorganic pigment coating 210 can be disposed on the film substrate 100 using an electroplating process. The inorganic pigment coating 210 can be manufactured using materials such as metal sulfides (e.g., cadmium sulfides) or metal compounds (e.g., copper compounds). The organic pigment coating 110 can be disposed on the film substrate 100 using a process similar to that used for film manufacturing. The organic pigment coating 110 can be manufactured using materials such as azo pigments or phthalocyanine pigments.

[0054] In some embodiments, there are multiple options for the film substrate 100. For example, the film substrate 100 may be a PET substrate (polyethylene terephthalate); for another example, the film substrate 100 may be a PP substrate (polypropylene).
