Description

Technical Field

[0001] This invention relates to the field of LED wall washer technology, and more specifically, to a lamp holder for a multifunctional LED wall washer. Background Technology

[0002] In existing technologies, LED wall washer lights are widely used in building facade lighting, and being exposed to the outdoor environment for extended periods, they face multiple challenges in use and maintenance. Firstly, because they are typically installed high on walls, if the lights fall due to fixation failure or structural aging, it not only damages the equipment but also poses a serious risk to personal safety. Therefore, extremely high requirements are placed on installation reliability and fall protection. Secondly, during outdoor operation, the light-emitting surface of wall washer lights easily accumulates dust, rain stains, bird droppings, and other contaminants. Over time, this layer of dirt significantly reduces light transmittance, weakening the brightness and uniformity of the illumination. However, traditional wall washer lights generally lack self-cleaning functions, typically requiring manual cleaning periodically by climbing to a height, which is not only costly and inefficient but also poses safety hazards associated with working at height. Summary of the Invention

[0003] To overcome the drawback that wall washer lights are generally installed on the exterior of buildings, and if they fall, they will not only damage the equipment but may also endanger personal safety, this invention provides a multifunctional LED wall washer light holder.

[0004] The technical solution is as follows: A multifunctional LED wall washer light holder includes a light holder and a bracket mounted on the light holder; a wall washer light is fixedly connected to the inner side of the bracket; it also includes a fixing component; a fixing component for mounting the light holder is connected to the lower side of the light holder; a mounting groove is opened on the right side of the light holder; a servo motor is fixedly connected in the mounting groove, and the output shaft of the servo motor is fixedly connected to the bracket; a sealing plate is detachably connected to the right side of the light holder; a fall arrestor is fixedly connected to the inner left and inner right sides of the light holder, and a flexible cleaning sleeve is covered on the surface of the fall arrestor for cleaning the lamp surface of the wall washer light; two limiting rods are fixedly connected to the inner left and inner right sides of the light holder, and each fall arrestor is located between the two limiting rods on the same side; each fall arrestor is S-shaped and wound around the two limiting rods, and the two fall arrestors are centrally symmetrically distributed.

[0005] Furthermore, the fall arrestor is made of stainless steel, and the cleaning sleeve covering it is a flexible fleece sleeve.

[0006] The above settings achieve the effects of preventing light fixtures from falling and removing dust from the surface of the wall washer lights.

[0007] To further address uneven wall surfaces, the fixing assembly includes a base; a rectangular groove is provided on the lower side of the lamp holder, and two bases are slidably connected within the rectangular groove; a mounting plate is slidably connected to each base; two springs are fixedly connected to the upper side of each mounting plate and are also fixedly connected to the base; a wedge block I is fixedly connected to the upper side of each mounting plate and is located between the two springs; a sliding groove is provided on the inner side of each base; a wedge block II is slidably connected within each sliding groove and fits against the wedge block I; a screw is rotatably connected to each wedge block II and is screwed to the base.

[0008] Furthermore, the light surface of the wall washer light is arc-shaped, the anti-fall cable is located below the wall washer light, and the anti-fall cable is initially distributed in a planar manner.

[0009] Furthermore, each fall arrestor is equipped with an installation ring.

[0010] Furthermore, a rubber gasket is provided on the lower surface of each mounting plate.

[0011] The above settings achieve the effect of shock absorption.

[0012] To further improve the cleaning efficiency of the flexible fleece cover, it also includes fixing blocks; two fixing blocks are fixed to the rear of the outer ring surface of the lamp holder; a water supply pipe is fixed to both fixing blocks; a water inlet is provided on the water supply pipe; and several nozzles are provided on the water supply pipe in an equidistant manner, with all nozzles facing the fall arrestor.

[0013] Furthermore, it also includes scraper strips; a scraper strip is fixed to both the front and rear sides of the wall washer light.

[0014] Furthermore, the limiting rod consists of a telescopic rod and a limiting sleeve. The telescopic end of the telescopic rod is fixedly connected to the limiting sleeve, and the fall arrestor is wound around the groove of the limiting sleeve.

[0015] Furthermore, each scraper is made of silicone.

[0016] The above settings achieve the function of deformable scraper strip, preventing the scraper strip from covering the flexible pile and scraping it off.

[0017] The beneficial effects of this invention are as follows: the fall arrestor not only has an emergency fall arrest function, but can also clean the wall washer light regularly. Then, clean water is delivered through the water pipe to wet the flexible fleece cover, which improves the cleaning effect. After cleaning, water is sprayed onto the fall arrestor through the nozzle to wash away the dust attached to the flexible fleece cover.

[0018] The multifunctional LED wall washer light holder obtained by the above design of the present invention has the following advantages: before cleaning, the flexible velvet sleeve is squeezed by the scraper to expel excess water, so that no water escapes when it is attached to the wall washer light surface. The advantage of this design is that even if the wall washer light ages due to long-term use and the sealing performance deteriorates, water will not enter the interior, thus not affecting its service life.

Figures 1-6 As shown, it includes a lamp holder 1, a bracket 2, and a wall washer light 3; the bracket 2 is rotatably mounted on the lamp holder 1; the wall washer light 3 is fixedly connected to the inner side of the bracket 2; It also includes a fixing component, a servo motor 4, a sealing plate 5, a fall arrestor 6, and a limiting rod 7; the fixing component is connected to the lower side of the lamp holder 1; the lamp holder 1 has a mounting groove 1001 on the right side; the servo motor 4 is bolted into the mounting groove 1001, and the output shaft of the servo motor 4 is fixedly connected to the bracket 2; the sealing plate 5 is detachably connected to the right side of the lamp holder 1, which seals the mounting groove 1001 to prevent rainwater and dust from entering the mounting groove 1001 and affecting the normal operation of the servo motor 4; a fall arrestor 6 is fixedly connected to the inner left and inner right sides of the lamp holder 1, and a flexible cleaning sleeve is covered on the surface of the fall arrestor 6; two limiting rods 7 are fixedly connected to the inner left and inner right sides of the lamp holder 1, and each fall arrestor 6 is located between the two limiting rods 7 on the same side; each fall arrestor 6 is S-shaped and wound around the two limiting rods 7, and the two fall arrestors 6 are centrally symmetrically distributed.

[0023] The fall arrestor 6 is made of stainless steel, and the cleaning sleeve covering its exterior is a flexible fleece sleeve.

[0024] The fixing assembly includes a base 101, a mounting plate 102, a spring 103, a wedge block 104, a wedge block 105, and a screw 106; a rectangular groove 1002 is provided on the lower side of the lamp holder 1, and two bases 101 are connected in a damped sliding manner in the rectangular groove 1002; a mounting plate 102 is slidably connected to each base 101; two springs 103 are fixedly connected to the upper side of each mounting plate 102, and the two springs 103 are fixedly connected to the base 101. Each mounting plate 102 has a wedge block 104 fixedly attached to its upper side, and the wedge block 104 is located between two springs 103; each base 101 has a sliding groove 10101 on its inner side; each sliding groove 10101 has a wedge block 2 105 slidably connected in its sliding groove, and the wedge block 2 105 is in contact with the wedge block 104; each wedge block 2 105 has a screw 106 rotatably connected to it, and the screw 106 is screwed to the base 101.

[0025] The wall washer light 3 has an arc-shaped lamp surface. The anti-fall cable 6 is located below the wall washer light 3 and is initially flat. The wall washer light 3 can rotate and squeeze the anti-fall cable 6 to make it arc-shaped and fit into the lamp surface of the wall washer light 3, thereby enhancing the cleaning effect on the lamp surface.

[0026] Each fall arrestor 6 is equipped with an installation ring 6001.

[0027] Each mounting plate 102 has a rubber gasket 10201 on its lower surface.

[0028] It also includes a fixing block 201, a water supply pipe 202, and a nozzle 203; two fixing blocks 201 are fixedly connected to the rear of the outer ring surface of the lamp holder 1; a water supply pipe 202 is fixedly connected to both fixing blocks 201; a water inlet 20201 is provided on the water supply pipe 202; a number of nozzles 203 are provided on the water supply pipe 202 in an equidistant manner, and all nozzles 203 face the fall arrestor 6.

[0029] It also includes a scraper 204; a scraper 204 is fixedly attached to the front and rear sides of the wall washer light 3.

[0030] The limiting rod 7 consists of a telescopic rod 71 and a limiting sleeve 72. The telescopic end of the telescopic rod 71 is fixed to the limiting sleeve 72, and the fall arresting cable 6 is wound around the groove of the limiting sleeve 72.

[0031] Furthermore, each scraper is made of silicone material (204).

[0032] The further advantage of using the above method is that it prevents the scraper 204 from scraping off the lint on the flexible lint cover during operation, thus affecting the cleaning effect of the flexible lint cover.

[0033] The working steps of this embodiment are as follows: The following directions are Figure 1 Using the reference angle, the direction where the lamp holder 1 is located is to the left. The following rotations refer to the viewing angles from front to back, from top to bottom, and from right to left. When installing this multi-functional LED wall washer light fixture on an uneven exterior surface, the operator first places the base 101 and mounting plate 102 on one side of the exterior surface. Then, the operator manually rotates the screw 106 on the other side, moving the corresponding wedge block 105 into the slide groove 10101 towards the wedge block 104. This pushes the wedge block 104 downwards, causing the mounting plate 102 to gradually move downwards within the base 101. The two springs 103 are forced to stretch until the rubber pad 10201 on the underside of the mounting plate 102 is in contact with the uneven exterior surface. The light fixture 1 is then adjusted to a horizontal position. The multi-functional LED wall washer light fixture is fixed in place by expansion bolts. The height between the base 101 and the mounting plate 102 can be adjusted by manually rotating the screw 106, adapting to uneven exterior surfaces. Compared to traditional wall washer lights, this eliminates the need for shims during installation, improving stability and making installation easier for operators. Furthermore, the rubber gasket 10201 on the underside of the mounting plate 102 not only adapts to complex walls such as curved and sloping surfaces but also prevents loosening due to vibration or thermal expansion and contraction, enhancing the practicality of the multi-functional LED wall washer light fixture.

[0034] After the lamp holder for this multi-functional LED wall washer light is installed, the operator connects an external power source to all electrically driven components on the lamp holder, connects an external water supply pipe to the water inlet 20201, and then drives the servo motor 4 through an external controller. This causes the output shaft to rotate the bracket 2 and the wall washer light 3, turning the lamp face of the wall washer light 3 outwards. The rotation angle of the servo motor 4 can be preset according to the desired wall surface illumination. When the wall washer light 3 is powered on, the lamp face of the wall washer light 3 will automatically rotate. The light is directed to the desired angle and illuminates the wall, achieving multi-angle adjustable and precise lighting effects for the wall washer light 3. Furthermore, two anti-fall ropes 6 are installed on the inner side of the light fixture 1, and the mounting rings 6001 at the ends of the two anti-fall ropes 6 are also fixed to the exterior of the building. When the base 101 is corroded or the bolts are loose, causing the light fixture to fall, the two anti-fall ropes 6 will suspend the light fixture, bear the entire weight of the light fixture, and prevent it from falling. This not only prevents equipment damage but also avoids the light fixture falling and endangering the safety of people below.

[0035] Since the wall washer light 3 is installed on the exterior of the building, dust accumulates on its surface during operation. Over time, this dust buildup increases, affecting the light intensity. Traditional wall washer lights 3 lack automatic dust cleaning, requiring manual cleaning, which is time-consuming, labor-intensive, and inefficient. Therefore, after the wall washer light 3 has been operating for a period of time, external equipment is used to supply water to the water pipe 202, causing several nozzles 203 to spray water onto the two fall arresting cables 6. After wetting the flexible fleece sleeves on the fall arresting cables 6, water supply to the nozzles 203 is stopped. Then, the output shaft of the servo motor 4 is controlled to rotate the bracket 2, the wall washer light 3, and the scraper 204 together. During rotation, one side of the scraper 204 contacts the fall arresting cable 6, squeezing it to remove excess water from the flexible fleece sleeves. Then, the wall washer light 3... Rotating and pressing the two anti-fall cables 6 causes the limiting sleeve 72 to slide, compressing the telescopic rod 71, so that the anti-fall cables 6 change from a planar distribution to an arc distribution to adapt to the shape of the wall washer light 3. Then, the flexible fleece sleeves on the anti-fall cables 6 clean the arc-shaped lamp surface of the wall washer light 3. After the lamp surface of the wall washer light 3 rotates away from the anti-fall cables 6, water continues to be supplied into the water pipe 202, so that the nozzle 203 sprays water at the two anti-fall cables 6 to wash away the dust adhering to the flexible fleece sleeves. Then, the scraper 204 on the other side will contact the anti-fall cables 6 to scrape away the excess water contained in the flexible fleece sleeves on the anti-fall cables 6. Then, it rotates in the opposite direction to clean the arc-shaped lamp surface of the wall washer light 3 again. Repeat the above steps 3-5 times to clean the lamp surface of the wall washer light 3. Then, control the servo motor 4 to drive the wall washer light 3 to rotate back to the initial working angle. This not only eliminates the need for manual cleaning of the dust on the lamp surface of the wall washer light 3, but also saves time and effort.

[0036] With the above design, the fall arrestor 6 not only has an emergency fall arrest function, but can also regularly clean the wall washer light 3. During the cleaning process, the water pipe 202 delivers clean water to wet the flexible fleece sleeve, improving the cleaning effect. Before cleaning, the scraper 204 will squeeze the flexible fleece sleeve to expel excess water, so that no water will escape when it is attached to the light surface of the wall washer light 3. In this way, even if the wall washer light 3 ages due to long-term use and its sealing performance deteriorates, water will not enter the interior, thus not affecting its service life. After cleaning, the nozzle 203 sprays water onto the fall arrestor 6 to wash away the dust attached to the flexible fleece sleeve. At the same time, the scraper 204 scrapes off excess water. This process can prevent dust from clumping when the flexible fleece sleeve is naturally air-dried, maintaining its cleaning efficiency.

[0037] It should be noted that when the wall washer light 3 stops pressing the anti-fall cable 6, the telescopic rod 71 will cause the limit sleeve 72 to automatically return to its original upward position, and the anti-fall cable 6 will change from an arc-shaped distribution back to a flat distribution.

[0038] It should be noted that the dust on the wall washer light 3 will fall down from the rectangular groove 1002, just as the water sprayed by the nozzle 203 will also be discharged from the rectangular groove 1002.

[0039] It should be noted that when the holes opened by the operator on the facade are misaligned, the base 101 can be pushed to move within the rectangular groove 1002, moving the base 101 and the connected components to the designated hole, making it easier for the operator to fix the base 101.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
