[0002] An LED wall washing light is a lighting device using an LED chip as a light source. Its main feature is that by adjusting the bidirectional light-emitting angle of the LED light source, the light can evenly and softly illuminate the wall surface like water, forming a planar light effect, so as to achieve the purpose of decorating and beautifying the environment.

[0003] Referring to the LED wall washing light source module, LED wall washing light, and LED lamp disclosed in the patent application with the publication number CN204534301U, a male connector and a female connector that cooperate with each other are provided at both axial ends of the LED wall washing light source module. The LED wall washing light source modules are connected through the male connector and the female connector. The assembly is simple, the maintenance is convenient, the components have strong universality and high reliability, and there is no dark area at the connection.

[0004] After comprehensively analyzing the above patents, the following defects are obtained:

[0005] In the current design of LED wall washing lights, the lamp beads are soldered on an aluminum substrate to form a lamp board. Although this design helps with heat dissipation and the compactness of the overall structure, when one of the lamp beads is damaged due to aging, overheating, or external impact, etc., due to their close arrangement and interconnection, it is inconvenient to repair and replace them, resulting in a poor lighting effect in a local area of the lamp board, thus affecting the lighting effect of the entire lamp board;

[0006] Since the lamp beads are fixed on the aluminum substrate, and the aluminum substrate is usually encapsulated inside the housing of the lamp, when it is necessary to repair or replace the damaged lamp beads, it is often necessary to disassemble the entire housing of the lamp, and even to untie complex circuit connections, resulting in a time-consuming and laborious disassembly and repair process, and may also cause damage to other parts of the lamp.

[0007] Therefore, the present invention proposes an LED wall washing light and method that are convenient for maintenance to solve the above problems. Summary of the Invention

[0029] The present invention provides a convenient-to-maintain LED wall washer and method. Compared with the prior art, it has the following beneficial effects:

[0030] 1. An LED wall washer and method that are convenient for maintenance. By setting a lock head assembly and a lock sleeve assembly, the light-transmitting protection cover and the lamp housing can be quickly assembled and disassembled. There is no need to use fasteners such as bolts to fix the light-transmitting protection cover, thus speeding up the installation and disassembly time of the light-transmitting protection cover, facilitating the maintenance operation of the LED wall washer, and shortening the maintenance time. Secondly, by rotating the variable pitch module, the effect of simultaneously driving multiple LED lamp head modules to move away from each other or approach each other at equal distances can be achieved. And when the LED lamp head modules move away from each other or approach each other at equal distances, they can be driven by the arc-shaped top block to move outwards through the maintenance opening, so that the LED lamp head modules are exposed outside the lamp housing. The purpose of isolating the LED lamp head modules can be achieved without completely disassembling the lamp housing, which greatly facilitates the maintenance or replacement operation of the LED lamp head modules by the staff, simplifies the maintenance steps of the LED lamp head modules, and thus greatly shortens the maintenance or replacement time of the LED lamp head modules. Moreover, by rotating the variable pitch module in the reverse direction, the multiple LED lamp head modules can be reset, so that they can be quickly reset after the maintenance or replacement of the LED lamp head modules, shortening the overall maintenance time of the LED wall washer, and enabling the maintenance and operation of multiple LED wall washers to be carried out within the same time.

[0031] 2. An LED wall washer and method that are convenient for maintenance. By setting the LED lamp head module, the lifting component and the lamp head component inside it are designed as a split type, which can separately disassemble and separate the lamp head quick-release component and the driving power supply in the lamp head component. And after the lamp head component is exposed outside the maintenance opening by using the variable pitch module, the lamp head quick-release component and the driving power supply, which are vulnerable parts, can be separately disassembled and repaired without interfering with other components, thus avoiding damage to other components during repeated disassembly and assembly, and prolonging the service life of other components of the LED wall washer.

[0032] 3. An LED wall washer and method that are convenient for maintenance. By setting multiple LED lamp head modules, each LED lamp head module is an independent unit. During the maintenance process, the variable pitch module can be used to separate the interconnected LED lamp head modules from each other, which is convenient for the staff to repair or replace the damaged LED lamp head module without interfering with other intact LED lamp head modules, greatly improving the convenience of the maintenance process. At the same time, after a certain LED lamp head module is damaged, it can be directly replaced without affecting the overall lighting effect of the LED wall washer, ensuring that the LED wall washer is always in the best lighting state.

The position of each lock head assembly 8 is correspondingly arranged with the position of one of the lock sleeve assemblies 9. After the locking plate 81 is lifted to the corresponding height, the lock tongue 83 can slide into the locking through groove 92 along the through groove 82.

[0060] Embodiment 3: The main difference between this embodiment and the second technical solution lies in: a LED wall washer lamp convenient for maintenance. The LED lamp head module 12 includes a lamp head sliding seat assembly, a lifting assembly arranged above the lamp head sliding seat assembly, and a lamp head assembly.

[0061] The lamp head sliding seat assembly includes a mounting seat 121 slidably arranged on the opposite side walls of two guide rails 10. Two power connection contact pieces one 122 and a driving rod 124 are fixedly arranged at the bottom of the mounting seat 121. The two power connection contact pieces one 122 are symmetrically arranged on both sides of the driving rod 124. Circular jacks are formed on both sides of the top of the mounting seat 121, and metal elastic pieces three are fixedly arranged on the inner walls of the circular jacks. The two power connection contact pieces one 122 are slidably arranged in two corresponding conductive sleeves 11, and the two power connection contact pieces one 122 are electrically connected to the positive and negative poles of an external power supply through wires respectively.

[0062] The lifting assembly includes a lifting plate 123 arranged on the top of the mounting seat 121. One conductive metal column 1215 is fixedly arranged on both sides of the bottom of the lifting plate 123. The two conductive metal columns 1215 are respectively slidably arranged inside one of the circular jacks. Power connection slots one 126 and power connection slots two 127 are formed on the top of the lifting plate 123 and at positions opposite to the two conductive metal columns 1215. Metal elastic pieces one are fixedly arranged on the inner walls of the power connection slots one 126 and the power connection slots two 127. The two metal elastic pieces one are electrically connected to the two conductive metal columns 1215 through wires respectively. Convex blocks 125 used in cooperation with the arc-shaped top block 14 are fixedly arranged on the front and rear sides of the outer wall of the lifting plate 123.

[0063] The lamp head assembly includes a driving power supply 128 detachably arranged on the top of the lifting plate 123 through bolts. On both sides of the bottom of the driving power supply 128, there are fixed power connection contact pieces II 129. The two power connection contact pieces II 129 are respectively slidably arranged inside the power connection slot I 126 and the power connection slot II 127, and the two power connection contact pieces II 129 are electrically connected to the metal elastic pieces I at the corresponding positions; in the middle area of the top of the driving power supply 128, there are two power connection slots III 1210. On both sides of the top of the driving power supply 128, there are fixed locking sleeves 1211. A lamp head quick-release assembly is arranged between the opposite side walls of the two locking sleeves 1211. On the inner walls of the two power connection slots III 1210, there are fixed metal elastic pieces II for supplying electric energy to the lamp head quick-release assembly. After the power connection plug 1213 is inserted into the corresponding power connection slot III 1210, it is electrically connected to the metal elastic piece II inside the power connection slot III 1210.

[0064] The lamp head quick-release assembly includes an LED lamp head 1212. On both sides of the bottom of the LED lamp head 1212, there are fixed power connection plugs 1213 corresponding to the positions of the two power connection slots III 1210. A ring is rotatably sleeved on the outer wall of the LED lamp head 1212. On both sides of the outer wall of the ring, there are fixed limit plates 1214. The two limit plates 1214 are respectively slidably arranged inside the locking sleeves 1211. On the inner wall of the locking sleeve 1211, there is a fixed strong magnet piece I. On the opposite side walls of the limit plate 1214 and the locking sleeve 1211, there is a fixed strong magnet piece II. The strong magnet piece I and the strong magnet piece II are magnetically connected; the two power connection plugs 1213 are respectively slidably arranged inside the two power connection slots III 1210 and are electrically connected to the metal elastic pieces II.

[0065] The variable pitch module 13 includes a transmission shaft 131 that rotates through the lamp housing 1. On both sides of the outer wall of the transmission shaft 131, there are variable pitch modules 13 that simultaneously drive multiple LED lamp head modules 12 to move away from or close to each other at equal intervals. The variable pitch module 13 includes spiral grooves one 132, spiral grooves two 133, spiral grooves three 134, and spiral grooves four 135 that are evenly opened on the outer wall of the transmission shaft 131. The driving rod 124 in each LED lamp head module 12 is slidably arranged in the spiral groove one 132 or spiral groove two 133 or spiral groove three 134 or spiral groove four 135 at the corresponding position; one end of the transmission shaft 131 rotates through the lamp housing 1 and is fixedly provided with a knob for conveniently manually rotating the transmission shaft 131; the lengths of the spiral groove one 132, spiral groove two 133, spiral groove three 134, and spiral groove four 135 only allow the LED lamp head module 12 at the corresponding position to slide a fixed distance inside the lamp housing 1. This fixed distance just enables multiple LED lamp head modules 12 to slide to the inspection port area at the corresponding position. After that, the variable pitch module 13 cannot continue to rotate and can only be rotated back to the original position. Since the area of the inspection port is larger than the projection area of the LED lamp head module 12 from top to bottom, when the LED lamp head module 12 moves horizontally and vertically simultaneously, it will not interfere with the inspection port and can pass freely.

[0066] The present invention also provides a maintenance method for an LED wall washer that is convenient for maintenance. The method includes the following steps:

[0067] Step 1. During maintenance, first release the locking effect of the quick-release component on the lamp housing 1 and the light-transmitting protective cover 4, and then lift the light-transmitting protective cover 4 upward to separate it from the lamp housing 1; the specific process is as follows: Pull the lock tongue 83 in the direction away from the locking plate 81 so that the lock tongue 83 slides out of the inside of the locking through groove 92 until the side wall of the baffle 84 abuts against the outer wall of the through groove 82, that is, the lock tongue 83 moves to the limit position. At this time, under the elastic force of the spring 86, the locking plate 81 slides upward along the outer wall of the spring 86, and the end of the lock tongue 83 close to the through groove 82 abuts against the outer wall of the square block 91 and cannot enter the locking through groove 92, thereby releasing the locking state of one pair of lock head components 8 and lock sleeve components 9. Similarly, the unlocking method of other lock head components 8 and lock sleeve components 9 is the same as the above method. After all the lock head components 8 and lock sleeve components 9 are unlocked, pull the light-transmitting protective cover 4 upward, and the light-transmitting protective cover 4 will slide away from the outer wall of the lamp housing 1. Since the magnetic dust-proof net 5 and the inspection port are connected by magnetic force, at this time, the magnetic dust-proof net 5 can be pulled outward to separate it from the inspection port;

[0068] Step 2: Manually rotate the pitch-changing module 13 to the extreme position, driving multiple LED lamp head modules 12 to move away from each other at equal intervals along its outer wall. After the LED lamp head module 12 is separated from the conductive sleeve 11, the power-off operation is completed. After the LED lamp head module 12 meets the arc-shaped top block 14 at the corresponding position, it is gradually pushed upward by the arc-shaped top block 14. The upper part of the LED lamp head module 12 is completely exposed outside the lamp housing 1. At this time, the staff repairs multiple LED lamp head modules 12 in sequence and replaces the damaged LED lamp head modules 12 correspondingly. The specific process is as follows: Manually rotate counterclockwise the knob at the end of the transmission shaft 131 exposed outside the lamp housing 1 until the transmission shaft 131 rotates to the extreme position and cannot rotate anymore;

[0069] While the transmission shaft 131 rotates, the driving rod 124 at the bottom of each LED lamp head module 12 slides along the inner wall of the corresponding spiral groove 132 or spiral groove 133 or spiral groove 134 or spiral groove 135. Multiple LED lamp head modules 12 move away from each other at equal distances. When the LED lamp head module 12 moves and meets the arc-shaped top block 14, the convex blocks 125 on both sides of the bottom of the lifting plate 123 climb upward along the inclined surface at one end of the corresponding arc-shaped top block 14. When the LED lamp head module 12 starts to climb, it just reaches the inspection port position. The top of the LED lamp head 1212 gradually rises upward from the inspection port and is exposed outside the lamp housing 1. When the convex block 125 slides to the highest point position at the top of the arc-shaped top block 14, the part above the lifting plate 123 is exposed outside the inspection port. At this time, rotate the limit plate 1214 clockwise so that the two limit plates 1214 are separated from the locking sleeve 1211, and then lift the LED lamp head 1212 upward to remove the LED lamp head 1212 from the top of the driving power supply 128. At this time, the LED lamp head 1212 can be detected or replaced;

[0070] Then, remove the bolts fixing the driving power supply 128 and the lifting plate 123, and lift the driving power supply 128 upward. The power connection contact piece two 129 at the bottom of the driving power supply 128 is separated from the power connection slot one 126 and the power connection slot two 127 at the top of the power connection slot two 127. Then, repair the circuit inside the driving power supply 128. If it is damaged, directly replace it with a new driving power supply 128;

[0071] Step 3: After the inspection of the LED lamp head module 12 is completed, reverse-rotate the variable pitch module 13 to the extreme position again. The multiple LED lamp head modules 12 return to their original positions, and the LED lamp head module 12 and the conductive sleeve 11 at the corresponding position complete electrical connection. Then, lock the position of the variable pitch module 13. Next, cover the light-transmitting protective cover 4 on the outside of the lamp housing 1 again, and use the quick-release component to lock the light-transmitting protective cover 4 and the lamp housing 1. The specific process is as follows: Reverse-rotate the transmission shaft 131 to its extreme position where it cannot rotate. The driving rods 124 at the bottoms of the multiple LED lamp head modules 12 slide along the inner walls of the corresponding spiral groove one 132, spiral groove two 133, spiral groove three 134, or spiral groove four 135. The multiple LED lamp head modules 12 move equidistantly in the direction of approaching each other until the LED lamp head 1212 moves to face the adjacent lens 6, ensuring that the light emitted by the LED lamp head 1212 can pass through the lens 6 and shine out. Then, cover the light-transmitting protective cover 4 on the outside of the lamp housing 1 and ensure that the lock head assembly 8 and the lock sleeve assembly 9 at the corresponding position are opposite. Next, press down the locking plate 81 so that the lock tongue 83 is opposite to the locking through groove 92. The lock tongue 83 slides into the locking through groove 92 along the inner wall of the through groove 82. After releasing the pressing on the locking plate 81, the elastic force of the spring 86 pushes the locking plate 81 to have a tendency to move upward, making the lock tongue 83 close to the inner wall of the through groove 82 and unable to move freely, realizing the mutual locking of the light-transmitting protective cover 4 and the lamp housing 1.
