Description

Technical Field

[0001] The present invention relates to the technical field of advertising display, and in particular to a low-power outdoor advertising screen. Background Art

[0002] Outdoor advertising screens are displays installed in public outdoor spaces for displaying advertising content such as images, text, and videos. They utilize optoelectronic technology to transmit information to the public and are a core component of modern outdoor advertising. They serve key functions, including information dissemination and city lighting. Existing Chinese patent publication number CN117218972B discloses a low-power outdoor advertising screen for shopping malls to address the issue of excessive power consumption by LED displays. However, this patent also suffers from the following drawbacks: First, the aforementioned patent uses the photovoltaic effect of solar panels to power the auxiliary light module. Solar panels generate electricity only under sunlight conditions. The power generation drops significantly at night, on rainy days, or in foggy and smoggy conditions. As a result, the auxiliary light module may stop lighting due to insufficient power. Secondly, when installing outdoor advertising screens, there may be other obstructing structures above the screens, such as eaves or terraces, to reduce direct sunlight that would otherwise cause the screens to appear whitish and the patterns to be blurred. These obstructing structures will affect the photovoltaic efficiency of the solar panels, ultimately causing the auxiliary light modules to be unable to properly illuminate the screens at night. Third, the illumination range of the auxiliary light module is limited. In actual use, the auxiliary light module can only illuminate a local area of ​​the display screen, which will cause an abnormally bright spot in a local area of ​​the display screen at night, thereby affecting the normal information display of the display screen.

[0018] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] refer to Figures 1 to 12 A low-power outdoor advertising screen shown in the figure includes an advertising board 1, a accommodating component and an auxiliary lighting component. The accommodating component includes a rectangular shell 2 and a strip shell 3. The strip shell 3 is horizontal, and the rectangular shell 2 is vertically fixed to the top of the strip shell 3. The advertising board 1 is vertically arranged in the rectangular shell 2, and the auxiliary lighting component is arranged in the strip shell 3. The auxiliary lighting component includes a transverse movement mechanism, a lighting mechanism, a lens mechanism and a push-pull mechanism. The transverse movement mechanism includes a movable base frame 4 and a support plate 5. The movable base frame 4 is slidably connected to the strip shell 3, and the support plate 5 is horizontally mounted above the movable base frame 4. The lighting mechanism includes a number of self-heating lamp modules 6 equidistantly distributed on the support plate 5 in the horizontal direction. The several self-heating lamp modules 6 are divided into a group of two. The lens mechanism includes a number of concave lenses 7, each concave lens 7 is arranged between a corresponding group of self-heating lamp modules 6, and the push-pull mechanism includes a push-pull frame 8 slidably connected to the movable base frame 4, and each concave lens 7 is fixed to the push-pull frame 8.

[0020] During actual processing, a perspective window 44 is provided on one side of the rectangular shell 2 for passers-by to view the information in the billboard 1. A support frame 45 is provided under the strip shell 3 for supporting the strip shell 3. The billboard 1 used in this device can be a static graphic board or an LED display board. In areas with large traffic, LED display boards can be used to attract the attention of passers-by. In areas with small traffic, static graphic boards can be used to reduce the corresponding power consumption. Several self-heating lamp modules 6 in the lighting mechanism are used to provide auxiliary lighting for the billboard 1 from bottom to top. Each self-heating lamp module 6 uses an independent circuit for start and stop. The self-heating lamp module 6 is divided into two usage conditions according to day and night: First, during the day, if the advertising board 1 used is an LED display board, in order to reduce direct sunlight on the LED display board, which causes the LED display board screen to be white and the pattern to be blurred, several self-heating lamp modules 6 will be fully turned on at noon, thereby increasing the brightness within the rectangular screen and reducing the impact of sunlight on the LED display board. After noon, several self-heating lamp modules 6 will be completely turned off, thereby reducing the corresponding power consumption. If the advertising board 1 used is a static graphic board, several self-heating lamp modules 6 will be fully turned off during the day, and at this time, only sunlight is used to display information on the static graphic board, thereby reducing power consumption; Secondly, at night, if the advertising board 1 used is an LED display board, several natural heat dissipation lamp blocks will be turned off at night. At this time, only the brightness of the LED display board itself is used to display information, and the brightness of the LED display board itself can also be adjusted down to further reduce power consumption. If the advertising board 1 used is a static graphic board, before nightfall, the push-pull frame 8 will drive several concave lenses 7 to move horizontally, so that each concave lens 7 is mounted above the corresponding self-heating lamp module 6, and then the self-heating lamp module 6 with the concave lens 7 is turned on, so that the remaining self-heating lamp modules 6 is in the closed state. When some of the self-heating lamp modules 6 are turned on, the light emitted therefrom will be dispersed by the concave lens 7 to expand the irradiation range of the self-heating lamp module 6. After that, the mobile base frame 4 will drive all the self-heating lamp modules 6 to move horizontally to adjust the irradiation direction of the light, ensuring that the light emitted when some of the self-heating lamp modules 6 are turned on can still fully cover the static graphic board. When the concave lens 7 is used, the irradiation range of the corresponding self-heating lamp module 6 is expanded, thereby reducing the number of self-heating lamp modules 6 that are turned on, thereby reducing power consumption.

[0021] In order to show the specific structure of each self-heating lamp module 6, the following features are set: Each self-heating lamp module 6 includes a chip holder 9, an LED chip 10, a heat conducting plate 11, a heat dissipating fin group 12, a fan housing 13 and a heat dissipating fan 14. The fan housing 13 is circular, the heat dissipating fan 14 is arranged in the fan housing 13, the heat dissipating fin group 12 is fixed on the top of the fan housing 13, the chip holder 9 is horizontally fixed on the top of the heat dissipating fin group 12, the LED chip 10 is horizontally fixed in the chip holder 9, and the heat conducting plate 11 is arranged between the LED chip 10 and the heat dissipating fin group 12.

[0022] During actual processing, a number of heat dissipation holes 46 are provided at the bottom of the strip shell 3. The LED chip 10 is a light-emitting component of the heat dissipation lamp module 6. During actual use, each LED chip 10 is provided with an independent wire and control switch. When the LED chip 10 emits light, the heat released by the LED chip 10 will be transferred to the heat dissipation fin group 12 through the thermal conductive sheet 11 for heat dissipation. At the same time, the heat dissipation fan 14 is started, and the heat on the heat dissipation fins is discharged through the heat dissipation holes 46 by the heat dissipation fan 14.

[0023] In order to show how each self-heating lamp module 6 is installed, the following features are set: The fan housing 13 is fixedly connected to the bottom of the support plate 5. The fan housing 13 presses the LED chip 10 to the bottom of the support plate 5 through the heat dissipation fin group 12. The support plate 5 is provided with a plurality of perforations 15 corresponding to the self-heating lamp module 6. A conical condenser 16 is fixed in each perforation 15. The small-diameter end of the condenser 16 faces the LED chip 10, and the large-diameter end faces the advertising board 1.

[0024] When the LED chip 10 emits light, the light will pass through the focusing shield 16 in the perforation 15 and be emitted toward the billboard 1. The focusing shield 16 concentrates the light, thereby increasing the illumination intensity of the LED chip 10 and preventing the light from the LED chip 10 from being too dispersed and unable to cross the entire billboard 1. When the light is emitted upward through the focusing shield 16, part of the divergent light will act on the billboard 1, and part of the divergent light will increase the brightness inside the rectangular shell 2. In this way, the self-heating lamp module 6 of the device does not directly illuminate the billboard 1, but displays the billboard 1 by increasing the brightness inside the rectangular shell 2, thereby preventing the billboard 1 from being too bright and affecting the normal display of information.

[0025] In order to show how the concave lens 7 is installed, the following features are set: Two symmetrical support bars 17 are mounted above the support plate 5, each support bar 17 is horizontal, and the push-pull frame 8 is arranged between the two support bars 17. The push-pull frame 8 includes two symmetrical strip rods 18, and a number of lens brackets 19 corresponding to the concave lenses 7 are fixed between the two strip rods 18. Each lens bracket 19 is annular, and each concave lens 7 is horizontally fixed in the corresponding lens bracket 19, and the concave surface of each concave lens 7 is facing upward. Each strip rod 18 is provided with a number of protrusions 20 mounted on the top of the support bar 17, and two symmetrical strip limit grooves 21 are opened on the support plate 5, and each strip rod 18 is formed with a limit rod 22 that passes vertically downward through the corresponding strip limit groove 21.

[0026] Each concave lens 7 is fixed between the two strip rods 18 through a lens bracket 19, and the two strip rods 18 are integrated through the connection of the lens bracket 19, so that the two strip rods 18 can synchronously drive several concave lenses 7 to translate. Each strip rod 18 slides horizontally on the support bar 17 through the corresponding protrusion 20. When the strip rod 18 drives the concave lens 7 to translate toward the corresponding self-heating lamp module 6, each concave lens 7 will eventually slide to the top of the focus cover 16. When processing the concave lens 7, the diameter of the concave lens 7 is larger than the diameter of the upper end of the focus cover 16. At this time, the light emitted from the focus cover 16 will be dispersed by the concave lens 7, thereby improving the illumination range of the corresponding LED chip 10. Among them, the limit rod 22 passing through the strip limit groove 21 prevents the strip rod 18 from shifting left and right during translation.

[0027] In order to show how the push-pull frame 8 moves in translation, the following features are set: A number of inverted L-shaped rods 23 are fixed on each strip rod 18, and each L-shaped rod 23 spans the corresponding support bar 17. The push-pull mechanism also includes a No. 1 cylinder 24 and a number of strip sliders 25 corresponding to the L-shaped rod 23. Each strip slider 25 is slidably connected to the movable base frame 4. A connecting rod 26 is provided between adjacent strip sliders 25 on the same side. The No. 1 cylinder 24 is horizontally fixed to the movable base frame 4. A connecting frame 27 connected to two of the strip sliders 25 is provided on the output end of the No. 1 cylinder 24. A No. 1 magnet 28 is provided at one end of each strip slider 25, and a No. 2 magnet 29 is provided at the lower end of each L-shaped rod 23 to magnetically cooperate with the No. 1 magnet 28.

[0028] When the output end of the No. 1 cylinder 24 is retracted inward, the several strip sliders 25 will drive the L-shaped rod 23 to move together through the magnetic attraction of the No. 1 magnet 28 and the No. 2 magnet 29, so that each concave lens 7 will be driven by the strip slider 25 to move between the corresponding two focusing shields 16.

[0029] In order to prevent the concave lens 7 that moves horizontally between the two heat dissipation lamp modules 6 from affecting the light emitted from the heat dissipation lamp module 6, the following features are set: Each support bar 17 is provided with a plurality of vertical through slots 30 for corresponding protrusions 20 to pass downwardly through, and a vertical upward stopper 31 is formed on the top of each support bar 17 .

[0030] When the output end of the No. 1 cylinder 24 retracts inward, several strip sliders 25 will drive the L-shaped rod 23 to move together through the magnetic attraction of the No. 1 magnet 28 and the No. 2 magnet 29. During this process, each concave lens 7 will be driven by the strip rod 18 to move between the corresponding two focusing covers 16. When the concave lens 7 is between the corresponding two focusing covers 16, one end of each strip rod 18 conflicts with the stopper 31, and each protrusion 20 is located above the corresponding through groove 30. Thereafter, as the output end of the No. 1 cylinder 24 continues to retract, the L-shaped rod 23 and The strip slider 25 will overcome the magnetic force of the first magnet 28 and the second magnet 29 and begin to separate. When the L-shaped rod 23 separates from the strip slider 25, the two strip rods 18 will drive the several concave lenses 7 to descend by themselves due to gravity. At this time, each protrusion 20 will be inserted downward into the corresponding through groove 30, and the L-shaped rod 23 will be downwardly mounted on the corresponding support bar 17. The L-shaped rod 23 is used to limit the descending stroke of each strip rod 18. When the concave lens 7 descends, the light emitted by the focus cover 16 will completely avoid the concave lens 7, thereby preventing the concave lens 7 from affecting the light emitted from the heat dissipation lamp module 6.

[0031] In order to show how to push the push-pull frame 8 in the lowered state upward, the following features are set: A top pin 32 is provided in each through slot 30 for sliding in the vertical direction, and an oblique wedge block 33 is formed at the lower end of the top pin 32. A horizontal bar 34 located below the support plate 5 is fixed on the top of each strip-shaped slider 25, and an inclined surface end 35 is formed at one end of the horizontal bar 34 for oblique wedge cooperation with the oblique wedge block 33.

[0032] When the concave lens 7 is lowered, each protrusion 20 will drop into the through groove 30 and conflict with the ejector pin 32 downward. At this time, the inclined wedge block 33 provided at the lower end of the ejector pin 32 will conflict with the top of the strip slider 25 downward, and the ejector pin 32 is in a descending state. When the output end of the No. 1 cylinder 24 extends outward, the strip slider 25 will drive the horizontal bar 34 to move toward the inclined wedge block 33. During this process, the inclined surface end 35 on the horizontal bar 34 will first conflict with the inclined wedge block 33. Through the cooperation of the inclined wedge, the ejector pin 32 will be driven to rise and lift the protrusion 20 to the outside of the through groove 30. Thereafter, as the output end of the No. 1 cylinder 24 continues to extend outward, the strip slider 25 gradually approaches the corresponding L-shaped rod 23. The rising inclined wedge block 33 will slide on the top of the horizontal bar 34, and the horizontal bar 34 will enable the top pin 32 to remain in the jacking state. Thereafter, when the No. 1 magnet 28 on the strip slider 25 is attracted by the No. 2 magnet 29 on the L-shaped rod 23, the L-shaped rod 23 will be driven by the strip slider 25 to translate. Finally, the two strip rods 18 will drive several concave lenses 7 to move toward the corresponding focusing cover 16. When the output end of the No. 1 cylinder 24 retracts inward, the inclined wedge block 33 will gradually slide along the horizontal bar 34 and fall onto the strip slider 25. When the inclined wedge block 33 falls, the top pin 32 will immediately fall, thereby ensuring that the subsequent protrusion 20 can fall into the through groove 30.

[0033] In order to show the specific structure of the traverse mechanism, the following features are set: The transverse movement mechanism also includes a No. 2 cylinder 36, which is horizontally fixed in the strip shell 3. A vertical connecting plate 37 is provided between the movable base frame 4 and the support plate 5, and the output end of the No. 2 cylinder 36 is fixedly connected to the vertical connecting plate 37.

[0034] When the concave lens 7 covers the corresponding focus cover 16, the No. 2 cylinder 36 is started, and the output end of the No. 2 cylinder 36 will drive the movable base 4 to move laterally in the strip shell 3 through the vertical connecting plate 37, so as to adjust the irradiation direction of the light after being dispersed by the concave lens 7.

[0035] In order to improve the lighting effect of the self-heating lamp module 6 on the advertising board 1, the following features are set: Light blocking plates 38 are fixedly provided at the left and right ends of the advertising board 1 in the rectangular shell 2 , and each light blocking plate 38 is vertical. A light reflecting plate 39 is fixedly provided at the top of the advertising board 1 in the rectangular shell 2 , and the light reflecting plate 39 is horizontal.

[0036] Two light-blocking plates 38 are used to block the light emitted from the heat dissipation lamp module 6 to prevent the light from being dispersed from both ends of the billboard 1. A reflector 39 provided on the top of the billboard 1 is used to reflect the light emitted from the heat dissipation lamp module 6 downward, thereby improving the lighting effect of the heat dissipation lamp module 6 on the billboard 1.

[0037] In order to facilitate the installation of the auxiliary lighting assembly and the advertising board 1, the following features are provided: Each strip shell 3 has a strip installation opening 40 on one side, which is covered with a strip cover 41 . Each rectangular shell 2 has a rectangular installation opening 42 on one side, which is covered with a rectangular cover 43 .

[0038] When installing the auxiliary lighting assembly, the strip cover 41 can be removed first, and then the auxiliary lighting assembly can be installed into the strip shell 3 through the strip installation opening 40. When installing the advertising board 1, the rectangular cover 43 can be removed first, and then the advertising board 1 can be installed into the rectangular shell 2 through the rectangular installation opening 42.

[0039] Working principle: During actual processing, a perspective window 44 is provided on one side of the rectangular shell 2 for passers-by to view the information in the billboard 1. A support frame 45 is provided under the strip shell 3 for supporting the strip shell 3. The billboard 1 used in this device can be a static graphic board or an LED display board. In areas with large traffic, LED display boards can be used to attract the attention of passers-by. In areas with small traffic, static graphic boards can be used to reduce the corresponding power consumption. Several self-heating lamp modules 6 in the lighting mechanism are used to provide auxiliary lighting for the billboard 1 from bottom to top. Each self-heating lamp module 6 uses an independent circuit for start and stop. The self-heating lamp module 6 is divided into two usage conditions according to day and night: First, during the day, if the advertising board 1 used is an LED display board, in order to reduce direct sunlight on the LED display board, which causes the LED display board screen to be white and the pattern to be blurred, several self-heating lamp modules 6 will be fully turned on at noon, thereby increasing the brightness within the rectangular screen and reducing the impact of sunlight on the LED display board. After noon, several self-heating lamp modules 6 will be completely turned off, thereby reducing the corresponding power consumption. If the advertising board 1 used is a static graphic board, several self-heating lamp modules 6 will be fully turned off during the day, and at this time, only sunlight is used to display information on the static graphic board, thereby reducing power consumption; Secondly, at night, if the advertising board 1 used is an LED display board, several natural heat dissipation lamp blocks will be turned off at night. At this time, only the brightness of the LED display board itself is used to display information, and the brightness of the LED display board itself can also be adjusted down to further reduce power consumption. If the advertising board 1 used is a static graphic board, before nightfall, the push-pull frame 8 will drive several concave lenses 7 to move horizontally, so that each concave lens 7 is mounted above the corresponding self-heating lamp module 6, and then the self-heating lamp module 6 with the concave lens 7 is turned on, so that the remaining self-heating lamp modules 6 is in the closed state. When some of the self-heating lamp modules 6 are turned on, the light emitted therefrom will be dispersed by the concave lens 7 to expand the irradiation range of the self-heating lamp module 6. After that, the mobile base frame 4 will drive all the self-heating lamp modules 6 to move horizontally to adjust the irradiation direction of the light, ensuring that the light emitted when some of the self-heating lamp modules 6 are turned on can still fully cover the static graphic board. When the concave lens 7 is used, the irradiation range of the corresponding self-heating lamp module 6 is expanded, thereby reducing the number of self-heating lamp modules 6 that are turned on, thereby reducing power consumption.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
