[0003] However, when the current projector lamp is emitting light, the light output range is narrow and the display effect is single. Moreover, when the projector lamp is not emitting light, the overall color of the projector lamp will not match the overall color of the display housing, and the overall appearance is very abrupt, affecting the user experience.

[0004] Therefore, how to improve the display effect and overall adaptability of projection lamps has become an urgent problem to be solved in this field. Utility Model Content

Subsequently, the concentrated light is dispersed by a second optical component closely connected to the first optical component, making it appear to have a fog effect, effectively improving the viewing angle and increasing the softness of the light.

When the projection lamp is turned off, there is no light inside the projection lamp structure, and the first preset color layer can be matched with the color of the display shell, so that there is no visual difference between the area of ​​the projection lamp structure and other areas of the display shell. This not only improves the display effect of the projection lamp structure, but also effectively improves the overall adaptability of the projection lamp structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present application is described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that, under the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Figure 1 This is a disassembly diagram of the assembly of the projection lamp structure and the housing in the first embodiment of the projection lamp structure of the present application. Figure 2 This is a schematic diagram of the first embodiment of the projection lamp structure of the present application, as shown in FIG. Figure 1 and Figure 2 As shown, an embodiment of the present application discloses a projection lamp structure 100, which is used to be connected to the rear shell 200 of the display device 10, and includes a lamp board 110, a first optical element 120 and a second optical element 130. The first optical element 120 and the second optical element 130 are sequentially arranged on one side of the light-emitting surface of the lamp board 110, and the first optical element 120 is connected to the second optical element 130; the first optical element 120 is used to refract or reflect the light irradiated by the lamp board 110, and the second optical element 130 is used to diffuse the light transmitted by the first optical element 120; there is a preset distance between the first optical element 120 and the lamp board 110, and a first preset color layer 140 is provided on one side of the light-emitting surface of the second optical element 130, and the first preset color layer 140 is made of a translucent material.

[0028] The present application has made improvements to the projection lamp structure 100. When the projection lamp structure 100 is turned on, the light emitted by the lamp board 110 is first refracted and reflected by the first optical element 120, so that the light scattered toward the edge of the lamp board 110 is concentrated toward the front, so that the unused light outside the viewing angle is recycled through the reflection and refraction of the first optical element 120, thereby reducing light loss and improving the overall brightness and uniformity. Subsequently, the concentrated light is dispersed by the second optical element 130 closely connected to the first optical element 120, making it look like an atomized effect. The viewing angle is effectively improved and the light is softer. At the same time, the divergent light blurs the boundary of the animation, making the animation effect displayed by the projection lamp structure 100 more three-dimensional. When the projection lamp is turned off, there is no light inside the projection lamp structure 100. The first preset color layer 140 can be matched with the color of the display housing 150, so that there is no visual difference between the area of ​​the projection lamp structure 100 and other areas of the display housing 150. This not only improves the display effect of the projection lamp structure 100, but also effectively improves the overall adaptability of the viewing experience of the projection lamp structure 100.

[0029] In the present application, the first optical element 120 can be a brightness enhancement film for improving the light transmittance and brightness; the second optical element 130 can be a diffuser for atomizing and diffusing the light transmitted by the first optical element 120; through the combination of the brightness enhancement film and the diffuser, the light emitted by the lamp board 110 is processed to make the picture more realistic, delicate and vivid; the lamp board 110 can be a lamp bead panel, and the light emission can be controlled by mobile phone software or computer software. Since the technology of using mobile phone software or computer software to control the light emission of the lamp board 110 is relatively mature, this application will no longer elaborate on the control of the light emission of the lamp board 110.

[0030] In addition, the projection lamp structure 100 of the present application adopts a design in which the brightness enhancement film and the diffuser are tightly attached, which can effectively reduce the overall thickness of the projection lamp structure 100. For example, the thickness of the projection lamp structure 100 is less than 7 mm during actual production, and is reduced to less than 5 mm when no other fixing parts 300 are required. This compact structural design not only greatly reduces the occupied space, but also makes it almost free of any restrictions in the length and width directions. Therefore, it can be flexibly applied to various scenarios, such as the front frame area of ​​the display. Moreover, the projection lamp structure 100 of the present application no longer carries an expensive display screen, and there is no need to customize a display screen of a specific size, thereby effectively reducing production costs.

[0031] Furthermore, the first preset color layer 140 is a single color layer or a mixed color layer, and the mixed color layer has at least two colors.

[0032] In this embodiment, the first preset color layer 140 can be a colored translucent sheet. During the actual installation process, the first preset color layer 140 can be directly attached to the light-emitting surface of the second optical element 130, or the first preset color layer 140 can be locked to the rear shell 200 of the display device 10 by screwing, ensuring that it corresponds to the light-emitting surface of the second optical element 130; the first preset color layer 140 can also be directly set at the position of the rear shell 200 corresponding to the installation position of the projection lamp structure 100.

[0033] The color of the first preset color layer 140 can be the same as or different from the color of the rear shell 200 of the display device 10. When the first preset color layer 140 is the same as the color of the rear shell 200 of the display device 10, when the projection lamp structure 100 is not emitting light, the overall color difference between it and the rear shell 200 is small or no color difference, and the overall visual experience is better. When the user has different color matching requirements, the first preset color layer 140 can be replaced to form a different color combination from the rear shell 200 of the display device 10.

[0034] Furthermore, when the projection lamp structure 100 emits light, the actual color of the first preset color layer 140 can be matched according to the actual needs of the user, so as to project different display effects using the projection lamp structure 100 .

[0035] Specifically, the first preset color layer 140 includes a black color layer 160, and the transmittance of the black color layer 160 ranges from 25% to 35%. Since the color of the rear cover 200 of a typical display is generally black, the first preset color layer 140 of the projection lamp structure 100 is set to be the black color layer 160. When the projection lamp structure 100 is not emitting light, there is no visual difference from other areas of the rear cover 200 of the display device 10. This improves the overall light consistency and helps improve the user experience.

[0036] In addition, the black color layer 160 is a translucent structure. When the transmittance of the black color layer 160 is lower than 25%, the display brightness of the projection lamp structure 100 may be lower. When the transmittance of the black color layer 160 is greater than 35%, the fog display effect of the projection lamp structure 100 may be reduced. Therefore, this application sets the transmittance of the black color layer 160 between 25% and 35%. For example: when the transmittance of the black color layer 160 is 30%, when the projection lamp structure 100 emits light, the black color layer 160 can serve as a projection carrier to display the picture constructed by the light source, and the display effect is better.

[0037] Furthermore, the first optical element 120 includes a prism layer 121, the prism layer 121 includes a plurality of lens structures 122 arranged at intervals, and a plurality of light-emitting units 111 are arrayed on the light board 110, and the center position of each light-emitting unit 111 corresponds to the connection position of two adjacent lens structures 122; or the center position of each light-emitting unit 111 corresponds to the center position of each lens structure 122.

[0038] When the light emitted by the light board 110 hits the prism layer 121 of the first optical element 120, the light will be refracted and reflected through a plurality of spaced-apart lens structures 122. When the center position of each light-emitting unit 111 on the light board 110 corresponds to the connection position of two adjacent lens structures 122, the light emitted by the light-emitting unit 111 can pass more through the edge of the lens structure 122. The curvature formed by the edge of the lens structure 122 allows the light to be refracted and reflected from different directions, increasing the number of light adjustments and making it easier for the light to be reconverged, thereby increasing the brightness of the front lighting.

[0039] When the center position of each light-emitting unit 111 corresponds to the center position of each lens structure 122, each lens structure 122 can receive as much light as possible emitted by the corresponding light-emitting unit 111, and more light can pass directly through the front of the lens structure 122, thereby effectively reducing light loss.

[0040] Since the light emitted by the light board 110 is first processed by the first optical element 120, and the distance between the first optical element 120 and the light board 110 directly affects the effect of the first optical element 120 reflecting and refracting the light emitted by the light-emitting unit 111 on the light board 110, thereby converging the edge light to the front, the present application also designs the distance between the first optical element 120 and the light board 110, as follows:

[0041] The distance between the first optical element 120 and the light board 110 ranges from 2.4 mm to 2.6 mm.

[0042] Such a distance range can guarantee the best visual experience and ensure the best balance between the clarity and three-dimensional effect of the picture. After repeated tests, it was found that the best distance between the first optical element 120 and the light board 110 is 2.55 mm, which not only avoids the scattering blur caused by excessive distance, but also avoids the flat and layerless picture caused by too close distance.

[0043] Figure 3 This is a schematic diagram of a second embodiment of the projection lamp structure of the present application, as shown Figure 3 As shown, the projection lamp structure 100 also includes a shell 150, and the shell 150 has an opening 151 on the side corresponding to the light-emitting surface of the lamp board 110, and the first optical element 120, the second optical element 130 and the lamp board 110 are all arranged in the shell 150; the first preset color layer 140 is installed at the opening 151 and is detachably connected to the shell 150; fixing parts 152 are respectively provided on the two opposite side walls of the shell 150, and the fixing parts 152 have a preset height relative to the lamp board 110; the first optical element 120 is provided with a mounting part 123 at the position corresponding to the fixing part 152, and the mounting part 123 is connected to the fixing part 152.

[0044] This embodiment differs from the previous embodiment in that, in this embodiment, the projection lamp structure 100 is an independent structure with a housing 150. The entire projection lamp structure 100 can be disassembled or assembled with the housing 150 and the rear housing 200 of the display device 10, and the internal components of the projection lamp structure 100, such as the first optical element 120, the second optical element 130, and the first preset color layer 140, can be disassembled or assembled with the housing 150.

[0045] Among them, the fixing part 152 of the shell 150 can be a socket, and the mounting part 123 of the first optical element 120 can be a protrusion. The protrusion is inserted into the socket to realize the plug-in fixation between the first optical element 120 and the shell 150, or the fixing part 152 of the shell 150 and the mounting part 123 of the first optical element 120 are both screw holes, and the first optical element 120 and the shell 150 are locked together with screws; and the installation between the first preset color layer 140 and the shell 150 can also adopt the same method as above.

[0046] In this embodiment, the adaptability of the projection lamp structure 100 to the installation of the rear housing 200 of display devices 10 of different sizes and specifications can be improved through the flexible assembly of the entire projection lamp structure 100 and its interior.

[0047] When the projection lamp structure 100 is damaged or needs repair, the entire projection lamp structure 100 can be removed from the rear shell 200 of the display device 10. The projection lamp structure 100 can be replaced separately, or the first optical element 120, the second optical element 130 and the first preset color layer 140 inside the projection lamp can be replaced and repaired, which is simple and convenient.

[0048] When the user has different color display requirements, the first preset color layer 140 can be directly replaced by removing the first preset color layer 140 from the shell 150 and then replacing it with a first preset color layer 140 of a different color according to actual needs to achieve different color display effects.

[0049] Furthermore, since the rear housings 200 of different display devices 10 have different sizes and specifications, when the projection lamp structure 100 is installed on the housing 150, it is generally necessary to design the spacing between the first optical element 120 and the lamp board 110 according to the corresponding installation position of the rear housing 200 to ensure that the optimal balance between the clarity and three-dimensional effect of the picture is achieved in the rear housing 200 of the corresponding specifications. Therefore, in order to improve the adaptability of the projection lamp structure 100 to be installed in the rear housings 200 of display devices 10 of different sizes and specifications, the present application also improves the projection lamp structure 100. The specific improvements are as follows:

[0050] Figure 4 This is a schematic diagram of a third embodiment of the projection lamp structure of the present application, as shown in FIG. Figure 4 As shown, Figure 4 The embodiment shown is based on Figure 3 In the improvement, there are multiple fixing parts 152, the multiple fixing parts 152 are arranged at intervals, and the multiple fixing parts 152 are arranged from the first preset color layer 140 to the direction of the light board 110.

[0051] This embodiment is different from the previous embodiment in that, in this embodiment, a plurality of fixing portions 152 are respectively provided on both sides of the shell 150 of the projection lamp structure 100, so that the first optical element 120 can be installed on the fixing portions 152 at different heights of the shell 150, thereby adjusting the distance between the first optical element 120 and the lamp board 110.

[0052] In this way, when the projection lamp structure 100 is installed on a rear shell 200 of different sizes and specifications, the distance between the first optical element 120 and the lamp board 110 in the projection lamp structure 100 can be adjusted accordingly according to the depth of the corresponding installation area 210 of the rear shell 200. This avoids scattering blur due to excessive distance and also avoids a flat and layerless picture caused by a too close distance, thereby ensuring an optimal balance between the clarity and three-dimensional effect of the picture.

[0053] Figure 5 This is a schematic diagram of the back of the rear shell of the first embodiment of the display device of the present application, as shown in FIG. Figure 5As shown, the embodiment of the present application further discloses a display device 10, comprising a rear housing 200. The display device 10 also comprises the aforementioned projection lamp structure 100, and the projection lamp structure 100 is connected to the rear housing 200. The rear housing 200 is used to carry the projection lamp structure 100 and protect the projection lamp structure 100, preventing damage to the projection lamp structure 100 due to external forces during transportation or movement of the display device 10. At the same time, installing the projection lamp structure 100 in the rear housing 200 of the display device 10 can also, to a certain extent, prevent external moisture and dust from entering the interior of the projection lamp structure 100, thereby affecting the display effect and service life of the projection lamp structure 100.

[0054] The display device 10 of the present application can be a display device such as a computer, a television, a conference machine, etc. The present application does not impose any specific restrictions on the type of the display device 10, as long as a projection structure can be installed on its rear shell 200.

[0055] In the current display device 10, when the projection lamp structure 100 is turned on, the light output range is narrow and the display effect is simple. When turned off, the entire projection lamp will appear to be mismatched with the overall color of the display back cover 200, resulting in poor overall adaptability and affecting user experience.

[0056] Based on the above problems, the present application improves the projection lamp structure 100 in the display device 10. When the projection lamp structure 100 is turned on, the light emitted by the lamp board 110 is first refracted and reflected by the first optical element 120, so that the light scattered toward the edge of the lamp board 110 is concentrated toward the front, so that the unused light outside the viewing angle is recycled through the reflection and refraction of the first optical element 120, thereby reducing light loss and improving the overall brightness and uniformity; then, the concentrated light is dispersed by the second optical element 130 closely connected to the first optical element 120, making it look like a fog effect, effectively improving the At the same time, the divergent light blurs the boundary of the animation, making the animation effect displayed by the projection lamp structure 100 more three-dimensional; when the projection lamp is turned off, there is no light inside the projection lamp structure 100, and the first preset color layer 140 can be matched with the color of the rear shell 200 of the display device 10, so that there is no visual difference between the area of ​​the projection lamp structure 100 and other areas of the rear shell 200 of the display device 10. This can not only improve the display effect of the projection lamp structure 100, but also effectively improve the overall adaptability of the projection lamp structure 100, thereby further improving the quality of the display device 10.

[0057] Figure 6 This is a schematic diagram of the front side of the rear housing of the second embodiment of the display device of the present application. Figure 6 As shown, Figure 6 The embodiment shown is based on Figure 5In the improvement, a mounting area 210 is provided on the rear shell 200, and a second preset color layer 220 is provided in the mounting area 210. The second preset color layer 220 is a single color layer or a mixed color layer, and the second preset color layer 220 is made of a translucent material.

[0058] This embodiment is different from the previous embodiment in that, in this embodiment, a second preset color layer 220 is further provided on the rear shell 200 of the display device 10. The second preset color layer 220 is used to make the installation area 210 of the rear shell 200 corresponding to the projection lamp structure 100 also have a colored translucent effect, wherein the color of the second preset color layer 220 can also be only a single color, or a mixture of multiple colors. The second preset color layer 220 can be the same as the color of the first preset color layer 140 in the projection lamp structure 100, or it can be different from the color of the first preset color layer 140 in the projection lamp structure 100. The specific design can match the actual color of the second preset color layer 220 according to the actual needs of the user, so as to combine with the first preset color layer 140 on the projection lamp structure 100 to produce different display effects.

[0059] When the second preset color layer 220 on the rear shell 200 and the first preset color layer 140 of the projection lamp structure 100 have the same color, the transmittance of the second preset color layer 220 and the first preset color layer 140 can be changed to achieve different display effects on light. For example, when the first preset color layer 140 and the second preset color layer 220 are both black translucent color layers, the transmittance of the first preset color layer 140 can be 25%, and the transmittance of the second preset color layer 220 can be 50%. In this way, the display effect has a better sense of layering and is easy to produce a three-dimensional effect.

[0060] When the colors of the second preset color layer 220 on the rear shell 200 and the first preset color layer 140 of the projection lamp structure 100 are different, the actual required color display effect can be achieved through different color combinations. For example, the second preset color layer 220 on the rear shell 200 can be a blue translucent layer, and the first preset color layer 140 of the projection lamp structure 100 can be a red translucent layer. The red translucent layer and the blue translucent layer can be combined to form a purple display effect. Of course, other color combinations are also possible. This embodiment only takes the second preset color layer 220 as a blue translucent layer and the first preset color layer 140 as a red translucent layer as an example. The specific design can match the actual color of the second preset color layer 220 according to the actual needs of the user, so as to achieve different display effects in combination with the first preset color layer 140 on the projection lamp structure 100.

[0061] Of course, in order to maintain the consistency of the overall appearance of the display device 10, the color of the second preset color layer 220 on the rear cover 200 generally needs to be the same as or similar to the overall color of the rear cover 200, so that the overall appearance is better.

[0062] In addition, in order to achieve the second preset color layer 220 on the rear shell 200 being able to be combined with the first preset color layer 140 of the projection lamp structure 100, the second preset color layer 220 can be prepared with the same material as the rear shell 200, and the entire rear shell 200 is designed to be detachable. For example: the second preset color layer 220 is made into a plate shape with the same material as the rear shell 200, and is screwed to the rear shell 200 in the installation area 210 by screw fixation, so that the user can replace the second preset color layer 220 of different colors according to actual needs and combine it with the first preset color layer 140 in the projection lamp structure 100, thereby showing different display effects as a whole and enriching the user experience.

[0063] In order to prevent the projection lamp structure 100 from falling off the rear housing 200 of the display device 10 and to improve the stability of the projection lamp structure 100 when mounted on the rear housing 200, the present application further improves the fixation between the projection lamp structure 100 and the rear housing 200. The specific improvements are as follows:

[0064] Figure 7 This is a schematic diagram of the back side of the rear housing of the third embodiment of the display device of the present application. Figure 7 As shown, Figure 7 The embodiment shown is based on Figure 5 In an improvement, the display device 10 further includes a fixing member 300 , which is arranged at a position corresponding to the installation area 210 and is used to fix the projection lamp structure 100 .

[0065] In this embodiment, the projection lamp structure 100 is fixed by an additional fixing member 300. When the projection lamp structure 100 is installed in the rear shell 200 of the display device 10, the fixing member 300 can be used to install it from the back of the projection lamp structure 100 to the installation area 210 of the rear shell 200. The fixing member 300 and the rear shell 200 can be fixed by screw locking. In this way, the projection lamp structure 100 can be confined to the installation area 210 of the rear shell 200. Even if the display device 10 is subjected to external force during movement or transportation, the projection lamp structure 100 will not fall off the rear shell 200.
