Description

Technical Field

[0001] The present invention relates to the technical field of lamp components, in particular to a mounting bracket for an LED wall washer lamp. Background Art

[0002] A wall washer is a lamp specially designed to illuminate walls, columns or other vertical surfaces. It is commonly used in indoor and outdoor lighting design to create an atmosphere, highlight architectural features or enhance the visual effect of a space. Wall washers can use various types of light sources, including LED lamps, fluorescent lamps and halogen lamps. LED wall washers are becoming more and more popular due to their advantages such as energy saving, long life and low heat.

[0003] LED wall washers are fixed to the corresponding area through mounting brackets. However, the existing mounting brackets for LED wall washers still have room for improvement in functionality during use, including:

[0004] Existing physical or patented mounting brackets have limited adjustment capabilities for light source angles, making it difficult to adapt to different projection requirements and directly meet users' different installation requirements in the middle of the wall, on top of the wall, and in the corners.

[0005] Many existing lighting devices lack dynamic effects in the display of mapping patterns, resulting in insufficient visual impact. The adjustment of the angle and projection position of the lamps requires complex manual operations. During use, traditional LED wall washers are easily affected by waste dust particles deposited on the surface of the light-transmitting surface. The lighting effect is also affected by suspended objects in high altitude areas, such as insects and fallen leaves that block light. To prevent harassment from mosquitoes and dust, electric mosquito repellents and filters are usually installed, but they require frequent maintenance and cleaning, which is relatively inconvenient. Summary of the Invention

[0006] (1) Technical Problems Solved: In response to the above-mentioned shortcomings of the prior art, the present invention provides an LED wall washer lamp mounting bracket, which can effectively solve the problems of the prior art.

[0007] (II) Technical Solution: To achieve the above objectives, the present invention is implemented through the following technical solution:

[0009] The mounting frame serves as a detachable carrier for mounting LED light sources and various functional accessories;

[0010] The motion structure is used to manually or programmatically select high-speed or low-speed control of the displacement posture of the light source, and cyclically or specifically switch the light irradiation mode between upward, downward, or both. In addition, under high-speed control, airflows with non-intersecting suction and exhaust directions are generated on both sides of the projection direction of the glass lens, respectively, to collect deposited objects in the light-transmitting area and expel suspended objects;

[0011] The switching structure is used to carry a mapping pattern that can be used for projection, and to keep the mapping pattern in a continuous displacement state when projected by the light source.

An air groove 1 is opened on the inner wall of the light-transmitting groove, and the air groove 1 is arranged obliquely downward at the outlet of the light-transmitting groove. The upper and lower ends of the air suction sleeve are connected to the air groove 1. During the rotation of the wind hood, negative pressure is generated inside, causing suction to be generated at the glass lens.

[0013] Furthermore, the end of the connecting tube away from the wind hood is fixedly connected to a rotating rod, the surface of the rotating rod is sleeved with a fan, the right end of the rotating rod is inserted with a connecting rod, the right end of the connecting rod is sleeved with a sleeve block, and two mounting balls fixedly connected to each other are provided inside the mounting frame shell, the left end of the mounting ball on the left side is fixedly connected to the right end of the sleeve block, the mounting ball is in a three-way groove state, and the interior of the three-way groove supports the installation of the LED lamp.

[0014] Furthermore, the surface of the connecting rod is rotatably connected to a sleeve rod, the top end of the sleeve rod passes through the mounting frame shell and extends to the outside of the mounting frame shell, the sleeve rod is slidingly connected to the mounting frame shell, and the sleeve rod is used to control the orientation of the connecting rod inside the rotating rod and the sleeve block, and select the synchronization and disconnection of the rotation relationship between the rotating rod and the hood.

[0015] Furthermore, the left end of the connecting rod surface is a polygonal block, the left inner wall area inside the rotating rod is a polygonal area, and the right inner wall area inside the rotating rod is a circular area. When the polygonal block at the left end of the connecting rod is located in the polygonal area, the rotation relationship between the rotating rod and the connecting rod is synchronized. When the polygonal block at the left end of the connecting rod is located in the circular area, the rotation relationship between the rotating rod and the connecting rod is disconnected.

[0016] Furthermore, two air outlet slots are respectively provided on the inner wall of the mounting frame shell, and a second air slot is provided on the side of the mounting frame shell close to the light-transmitting slot, and the second air slot is arranged obliquely upward at the outlet of the mounting frame shell, and the second air slot is connected to the air outlet slot.

[0017] Furthermore, the switching structure includes a worm, which is located inside the mounting frame shell, and the surface of the worm is rotatably connected to a fixing frame, which is fixedly connected to the inside of the mounting frame shell, and the middle of the fixing frame is rotatably connected to worm gear 2, and the back of worm gear 2 is fixedly connected to bevel gear 2, and the surface of the connecting rod is sleeved with bevel gear 1, and bevel gear 1 is meshed with bevel gear 2. Conveyor belts are respectively provided on the upper and lower sides of the interior of the mounting frame shell, and transmission rollers are sleeved at both ends of the transmission belt. The front and rear ends of the transmission roller are respectively connected to the front and rear ends of the transmission belt, and the front sides of the transmission rollers on the left are fixedly connected to worm gear 1, and the worm is meshed with worm gear 1 and worm gear 2.

[0019] Furthermore, the fixed conveyor belt follows the control states of high speed, low speed and pause, corresponding to the circular flow, low speed switching and fixed delivery of the projection scheme. The basic attributes of the projection scheme include: the projection direction of the light source and the change speed of the pattern projection, among which:

[0020] Circular flow: The mapping pattern moves rapidly, receiving illumination from the upper or lower light source, forming a high-speed flashing display pattern;

[0021] Low-speed switching: The mapping pattern moves at a constant speed, receiving illumination from the upper or lower light source to form a constant-speed display pattern;

[0022] Fixed projection: The mapping pattern remains stationary, receiving illumination from upper or lower light sources to form a fixed display pattern.

[0024] (III) Beneficial effects: Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0025] 1. By providing a hood, a fan, a first wind trough and a second wind trough, when the device is equipped with a light source and is in operation, the hood can be used to generate an inlet airflow at one wind trough on the light-transmitting surface of the glass lens, and the fan can be used to generate an outlet airflow at the second wind trough. The inlet airflow and the outlet airflow are generated synchronously, and act on the low and high altitude areas of the light-transmitting surface of the glass lens respectively without interfering with each other, thereby absorbing the deposited waste particles in the low altitude area of ​​the light-transmitting part to prevent them from re-forming into dust. In the process, air replacement is performed to weaken the formation of condensed water droplets caused by temperature difference at the glass lens, and directly expel suspended objects in the high altitude area, such as light-loving mosquitoes. The fallen leaf covering deviates the falling direction from the light-transmitting surface to avoid direct contact between mosquitoes and debris such as fallen leaves, and prevent them from blocking and polluting the light-transmitting surface, thereby maintaining the light-transmitting effect and reducing the maintenance cost of the device.

[0026] 2. By providing a mounting ball, a connecting rod and a sleeve rod, when the user installs the light source to the mounting ball, the user can switch the disconnection and synchronization states of the connecting rod and the rotating rod according to the illumination needs, and control the illumination direction of the light source of the mounting ball in three directions in a way of focusing near the wall. Therefore, the device can adapt to positions such as the middle of the wall, the top of the wall and the foot of the wall, and switch between different positions and postures according to the rotation state of the hood, thereby providing users with multiple possibilities when designing projection plans.

[0027] 3. By setting up a switching structure, the conveyor belt fixes a certain mapping pattern. When the device is in operation, the light source passes through the mapping pattern and is projected onto the wall. The conveyor belt runs synchronously with the start of the hood, so that the mapping pattern can be continuously switched in this process. As the height, average speed and low speed of the hood movement are adjusted, the display state of the mapping pattern on the surface of the conveyor belt is synchronously adjusted from high-speed flashing, average speed and fixed display. The free switching between solid and dynamic light and shadow effects can better attract the audience's attention, enhance visual impact, and increase the audience's interest and participation.

[0043] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] The present invention will be further described below with reference to the embodiments.

[0045] Example 1: This embodiment is a LED wall washer lamp mounting bracket, such as Figures 1-10 As shown, it includes a mounting frame 101, and two light-transmitting grooves 102 are provided on the upper and lower sides of the mounting frame 101. Glass lenses 103 are installed inside the light-transmitting grooves 102. A motion structure and a switching structure are provided inside the mounting frame 101, wherein:

[0046] The mounting frame 101 serves as a detachable carrier for mounting the LED light source and various functional accessories. Two air outlet slots 210 are respectively provided on the inner wall of the mounting frame 101. A second air outlet slot 212 is provided on the side of the mounting frame 101 near the light-transmitting slot 102. The second air outlet slots 212 are both arranged obliquely upward at the outlet of the mounting frame 101 and are connected to the air outlet slot 210.

[0047] An ash groove 400 is provided at the bottom of the mounting frame housing 101 near the hood 202, and a cover plate 500 is slidably connected to the interior of the ash groove 400;

[0048] The motion structure is used to manually or programmatically select high-speed or low-speed control of the displacement posture of the light source, and cyclically or specifically switch the light irradiation mode upward, downward, or both upward and downward. In the high-speed control state, non-intersecting airflows are generated on both sides of the projection direction of the glass lens 103, respectively, to collect deposited objects in the light-transmitting area and expel suspended objects;

[0049] Specifically, it includes: a servo motor 201, which is installed inside the mounting frame 101 and can receive manual active triggering or automatic triggering according to the default program setting. A hood 202 is fixedly connected to the output end of the servo motor 201, and the right end of the hood 202 is fixedly connected to the connecting tube 203. The surface of the connecting tube 203 is rotatably connected to the air suction sleeve 205, and the air suction sleeve 205 is connected to the connecting tube 203. An air groove 211 is opened on the inner wall of the light-transmitting groove 102, and the air groove 211 is arranged obliquely downward at the outlet of the light-transmitting groove 102. The upper and lower ends of the air suction sleeve 205 are connected to the air groove 211. During the rotation of the hood 202, negative pressure is generated inside, so that suction is generated at the glass lens 103.

[0050] The end of the connecting tube 203 away from the hood 202 is fixedly connected to the rotating rod 204, and the surface of the rotating rod 204 is sleeved with a fan 206. The right end of the rotating rod 204 is inserted with a connecting rod 207, and the right end of the connecting rod 207 is sleeved with a sleeve block 208. Two mounting balls 209 fixedly connected to each other are provided inside the mounting frame shell 101. The left end of the left mounting ball 209 is fixedly connected to the right end of the sleeve block 208. The mounting ball 209 is in a three-way groove state. The LED lamp is installed inside the three-way groove of the mounting ball 209. The lamp is installed inside the three-way groove of the mounting ball 209, so that the light source can be evenly diverged through the mounting ball 209 groove. This can ensure that the light coverage area is wider and reduce the problem of uneven brightness caused by direct light source, thereby realizing the flexible adjustment of the illumination angle of the mounting ball 209. This design allows the light source to flexibly adjust the projection direction according to needs, thereby improving the convenience of use;

[0051] The surface of the connecting rod 207 is rotatably connected with a sleeve rod 213, and the top end of the sleeve rod 213 passes through the mounting frame shell 101 and extends to the outside of the mounting frame shell 101. The sleeve rod 213 is slidably connected to the mounting frame shell 101, and the sleeve rod 213 is used to control the orientation of the connecting rod 207 inside the rotating rod 204 and the sleeve block 208, and select the synchronization and disconnection of the rotation relationship between the rotating rod 204 and the wind hood 202. The left end of the surface of the connecting rod 207 is a polygonal block, the left inner wall area inside the rotating rod 204 is a polygonal area, and the right inner wall area inside the rotating rod 204 is a circular area. When the polygonal block at the left end of the connecting rod 207 is located in the polygonal area, the rotation relationship between the rotating rod 204 and the connecting rod 207 is synchronized. When the polygonal block at the left end of the connecting rod 207 is located in the circular area, the rotation relationship between the rotating rod 204 and the connecting rod 207 is disconnected.

[0052] Compared with the existing technology, in the normal projection state, the user activates the servo motor 201, which drives the wind cap 202, the connecting tube 203 and the rotating rod 204 to rotate, effectively sucking away the dust and moisture deposited on the surface of the glass lens 103. This not only reduces the maintenance workload, but also ensures the normal operation and long-term use of the light source. The designed airflow absorption mechanism can effectively absorb the debris on the surface of the glass lens 103. At the same time, the discharged airflow can block mosquitoes, fallen leaves and other substances at a certain height, thereby protecting the light source and extending the service life of the device.

[0053] It not only has basic lighting functions, but also has multiple functions such as dust collection, dehydration, barrier and insect prevention, which makes its application range more extensive and can meet the needs of various places such as homes and businesses.

[0054] Embodiment 2: In other aspects, this embodiment also provides a switching structure for carrying a mapping pattern that can be used for projection, and making the mapping pattern in a continuous displacement state when projected by the light source, such as Figure 2 and Figure 4As shown, it specifically includes: a worm 301, which is located inside the mounting frame housing 101, and the surface of the worm 301 is rotatably connected to a fixing frame 308, which is fixedly connected to the inside of the mounting frame housing 101, and a worm gear 2 307 is rotatably connected to the middle of the fixing frame 308, and the back of the worm gear 2 307 is fixedly connected to the bevel gear 2 303, and the surface of the connecting rod 207 is sleeved with a bevel gear 1 302, and the bevel gear 1 302 is meshed with the bevel gear 2 303, and a transmission fixed belt 305 is respectively provided on the upper and lower sides of the mounting frame housing 101, and both ends of the transmission fixed belt 305 are sleeved with transmission rollers 304, and the front and rear ends of the transmission roller 304 are respectively transmission-connected to the front and rear ends of the transmission fixed belt 305, and the front sides of the left transmission roller 304 are fixedly connected to the worm gear 1 306, and the worm 301 is meshed with the worm gear 1 306 and the worm gear 2 307;

[0055] The ends of the conveying and fixing belts 305 that are away from each other are in the shape of continuous slots, which are used to fix the mapping pattern. The ends of the conveying and fixing belts 305 that are close to each other are in the shape of complete slots, which are used to present the projected content twice during the process of the mapping pattern following the conveying and fixing belts 305 in a single cycle. The mapping pattern template fixed on the surface of the conveying and fixing belts 305 can be flexibly replaced according to user needs, so that the projected pattern shapes are diverse, different visual effects can be achieved in different occasions, and the decorativeness of the lamp is enhanced.

[0056] Compared with the existing technology, it allows free switching between high-speed flashing, uniform speed and fixed display states, which can meet the needs of different occasions and scenes and provide a richer and more diverse visual experience. This flexibility is often difficult to simply achieve in the existing technology. The switching of the mapping pattern display on the surface of the conveyor fixed belt 305 can be achieved through simple adjustment. The operation is intuitive and easy to understand. This has more advantages than traditional manual or complex electronic control, making the device more convenient to use. Traditional projection is mostly static, while this device realizes dynamic display of the mapping pattern through synchronous operation and adjustment.

[0057] According to the changes in motion status and display requirements, more targeted energy adjustment can be achieved, which helps to reduce electricity consumption and has more energy-saving advantages compared to some fixed-mode lighting equipment.

[0058] Example 3: In this example, an adjustment scheme for the fixed conveyor belt 305 is provided. Specifically, the fixed conveyor belt 305 follows the high-speed, low-speed, and paused rotation states of the output end of the servo motor 201, corresponding to the cyclic flow, low-speed switching, and fixed delivery of the projection scheme. The basic attributes of the projection scheme include: the projection direction of the light source and the change speed of the pattern projection, which are as follows:

[0059] Circular flow: The mapping pattern moves rapidly, receiving illumination from the upper or lower light source, forming a high-speed flashing display pattern;

[0060] Low-speed switching: The mapping pattern moves at a constant speed, receiving illumination from the upper or lower light source to form a constant-speed display pattern;

[0061] Fixed projection: The mapping pattern remains stationary, receiving illumination from upper or lower light sources to form a fixed display pattern.

[0062] Compared with the existing technology, the invention can flexibly follow the rotation state of the output end of the servo motor 201 and switch between high speed, low speed and pause states, so that the projection scheme can adapt to environmental changes and user needs in real time, improving the flexibility and applicability of the projection effect. Through three different projection modes of circular flow, low-speed switching and fixed projection, users can choose different display effects according to actual needs, thereby achieving a diverse visual experience. The direction of the light source projection and the speed of the pattern projection change can be precisely controlled to ensure that the projected pattern is completely consistent with the required display content, thereby improving the controllability and stability of the effect.

[0063] Especially in the circular flow mode, the interaction between the fast-moving mapping pattern and the flashing of the upper or lower light source helps to create a strong visual impact and attract the audience's attention. The projection method in different modes can be adjusted according to actual needs. The effect can be displayed in a short time when running at high speed, while low-speed switching and fixed delivery can reduce unnecessary energy consumption and achieve resource conservation.

[0064] Working Principle: When using the present invention, the mounting frame 101 is disassembled and opened, and the LED lamp is installed inside the three-way groove of the mounting ball 209, so that the light source can be evenly dispersed through the three-way groove of the mounting ball 209. An external power supply is provided for the lamp and the servo motor 201. The mapping pattern template to be projected is fixed to the surface of the conveyor fixed belt 305. Then, the mounting frame 101 is re-fixed and fixed to the wall surface, such as the middle area of ​​the wall surface, by fixing means such as screwing.

[0065] When the device is deployed in the middle area of ​​the wall, when the user needs to project a light pattern upwards, such as Figure 2 As shown, the lamp in the installation ball 209 is started, so that the light source passes through the installation ball 209 and sequentially through the mapping pattern template fixed on the surface of the conveyor fixed belt 305 and the glass lens 103 to be projected onto the upper wall;

[0066] In the normal projection state, if the user needs to deal with waste particles such as dust deposited on the surface of the glass lens 103, evaporate the water vapor on the surface of the glass lens 103, and block mosquitoes attracted by the light, the servo motor 201 can be started, so that the servo motor 201 synchronously drives the wind cap 202, the connecting tube 203 and the rotating rod 204 to rotate. During this process, the wind cap 202 generates negative pressure inside during the rotation, so that the connecting tube 203 rotates with the support of the suction sleeve 205, so that the light-transmitting groove 102 connected to the suction sleeve 205 generates a suction airflow, which absorbs the dust and water vapor on the surface of the glass lens 103, and the rotating rod 204 generates an exhaust airflow. Figure 8 and Figure 10 As shown, the exhaust airflow is discharged through the air outlet slot 210, blocking mosquitoes and fallen leaves in the high altitude area of ​​the glass lens 103 to prevent them from contacting the glass lens 103. The absorbed dust falls into the dust groove 400, and the user can clean it later by opening the cover 500;

[0067] If you need to switch the installation ball 209 to a different irradiation angle, such as Figure 3 、 Figure 6 and Figure 8 As shown, the user can push the sleeve rod 213 in advance to drive the connecting rod 207 to move between the rotating rod 204 and the sleeve block 208, so that the polygonal block at the left end of the connecting rod 207 is inserted into the polygonal groove of the rotating rod 204. At this time, when the rotating rod 204 is in a rotating state, the mounting ball 209 is adjusted to a specified position or rotates synchronously according to the rotation speed of the rotating rod 204;

[0068] Similarly, when the rotating rod 204 is in a rotating state, it drives the bevel gear 2 303 to rotate through the bevel gear 1 302, and the bevel gear 2 303 relies on the fixed frame 308 to drive the worm gear 2 307 to rotate, and the worm gear 2 307 drives the worm 301 to rotate, and the worm 301 drives the worm gear 1 306 located on its upper and lower sides to rotate, and the worm gear 1 306 drives the transmission roller 304 to rotate, thereby rotating the conveyor fixed belt 305. The user can adjust the movement state of the fixed mapping pattern template on the surface of the conveyor fixed belt 305 by controlling the start and stop state and speed of the servo motor 201 according to needs.

[0069] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
