Description

Technical Field

[0001] This utility model relates to the field of wall washer light technology, and in particular to a 360-degree one-piece molded flexible IP68 waterproof lens wall washer light. Background Technology

[0002] The manufacturing process of waterproof wall washer lights in the existing technology is basically the same in terms of the electronic aspects of the lamp. First, the FPC is designed according to the product planning parameters, a suitable control method is selected, and the LEDs and electronic components are mounted on the front of the FPC to prepare the light strip. Then, the lens is centered and covers the LED with UV adhesive, silicone rubber or epoxy adhesive. The bottom of the FPC is then glued to the bottom of the TPU groove or silicone groove (the inner surface of the groove must be treated with silicone treatment agent), the two ends of the U groove are sealed, and then glue is dripped. After the glue dries, the finished product is tested and inspected to complete the production of the lamp.

[0003] Current waterproof wall washer lights typically consist of a light strip, adhesive tray, adhesive, and wiring. The light strip generally uses DC 5V / 12V / 24V power supply, and control schemes include resistor voltage divider current limiting, constant current element current limiting, and programmable ICs. Lighting effects include monochrome, white light, RGB seven-color, and RGB. The manufacturing process includes: surface mount technology (SMT) process (SMT equipment: solder paste printer, surface mount machine, reflow soldering), lens mounting, soldering of connecting boards, applying adhesive to the back of the light strip, attaching the light strip to the bottom of the TPU or silicone tray, and applying adhesive until it cures.

[0004] Current wall washer lights have the following drawbacks:

[0005] 1. If the wall washer light is bent, the lens and sealant will peel off, and the light fixture may lose its waterproof function;

[0006] 2. The silicone or TPU groove on the base plate has weak adhesion to the PU, and it is easy to delaminate during use, losing its waterproof function;

[0007] 3. The base material TPU is prone to hardening and yellowing, or the base material silicone will continuously volatilize silicone oil molecules, which will cause the adhesive joint to separate. Utility Model Content

[0032] The functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model proposes a one-piece molded waterproof wall washer light, specifically a 360-degree one-piece molded flexible IP68 waterproof lens wall washer light. This one-piece molded waterproof wall washer light is suitable for niche markets within the LED lighting industry, and is particularly well-suited for illuminating surfaces such as facades, outdoor walls, and eaves with high waterproofing requirements.

[0035] like Figures 1 to 4As shown, a preferred embodiment of the one-piece molded waterproof wall washer light of this utility model includes: an FPC circuit board 1, several LED lights 2, several resistors 3, several lenses 4, and wires 5; the LED lights 2 and the resistors 3 are attached to the FPC circuit board 1, the lenses 4 are disposed outside the LED lights 2, and the wires 5 are disposed at both ends of the FPC circuit board 1 for supplying power to the LED lights 2.

[0036] The FPC circuit board 1, several LED lights 2, several resistors 3, lens 4, and wires 5 are integrally encapsulated with waterproof PU glue 6.

[0037] This embodiment primarily upgrades the product's waterproof performance by integrally encapsulating the FPC circuit board 1, several LED lights 2, several resistors 3, lens 4, and wires 5 with waterproof PU adhesive 6. This embodiment improves the encapsulation and sealing process during manufacturing by using a new formula and sealing materials; a specially formulated PU adhesive 6 is used to address the requirement of strong adhesion between the sealant and the lens 4PC, preventing easy peeling; 360-degree one-time integral encapsulation molding is achieved, simultaneously encapsulating the wires and eliminating the need for end caps; the innovative tooling fixtures allow for extension, theoretically enabling longer products. Depending on production site and engineering product design requirements, a one-time molding length of up to 15 meters can be achieved.

[0038] In this embodiment, the lens 4 is a PC lens 4, and the waterproof PU adhesive 6 has good adhesion and fluidity to the PC lens 4, which can prevent the adhesive from peeling off from the lens 4.

[0039] This embodiment eliminates the existing TPU or silicone base plate for attaching light strips. The light strip is centered and fixed in the potting fixture. The dispensing machine mixes the PU glue 6 in the correct proportions and weight, calibrates the nozzle position, and injects PU glue 6 from the side seam of the dispensing tank. The glue penetrates from the bottom and emerges from the gap on the opposite side of the dispensing tank, filling the tank and self-leveling. After static inspection, the fixture is pushed off the dispensing machine's worktable and moved to a rack to dry. This embodiment innovates an integrated, one-time potting process, wrapping the light strip 360 degrees in the glue, achieving an IP68 waterproof effect. The fixture is long and narrow, typically 5 meters long. Depending on the production space, three 5-meter fixtures can be connected. Because long fixtures are difficult to move, a smooth conveyor belt is added to both ends of the machine's inlet and outlet, allowing a 15-meter fixture to be pushed back and forth in a straight line along the machine's work surface. This innovation allows a standard 5-meter wall washer light to be made 15 meters long.

[0040] Furthermore, in this embodiment, the FPC circuit board 1 is strip-shaped. The FPC circuit board 1 is provided with scissor positions 7.

[0041] In this embodiment, the waterproof PU adhesive 6 is a liquid two-component polyurethane (PU). The lens 4 is a PC lens 4.

[0042] In this embodiment, the one-piece molded waterproof wall washer light is powered by DC5V, DC12V, or 24V.

[0043] The control methods for the one-piece molded waterproof wall washer light include resistor voltage divider current limiting, constant current transistor / diode current limiting, constant current IC current limiting, or control IC current limiting.

[0044] The LED light 2 emits a single color, or white light, or seven colors, or a multi-colored light.

[0045] It should be noted that the LED light source model, product voltage, control method, light emission color, FPC width, finished product specifications, number of LEDs per group, number of segments per meter, and other parameters in this embodiment are based on design specifications and are not limited to the product design parameters of this application. This product description takes SMD2835 DC24V constant voltage 42 lamps / M 42 segments (one lamp / segment) FPC18mm, finished product size W20H06 15W / mw as an example.

[0046] The specific manufacturing process of this one-piece molded waterproof wall washer light is as follows:

[0047] A. First, embed the W20H06 silicone groove into the fixing aluminum profile;

[0048] B. Center the finished LED strip in the molding silicone (a 20cm fixing clip is used to center and fix the FPC in the silicone, ensuring a 1cm gap on the left / right / bottom of the FPC).

[0049] C. Calculate the amount of glue in 1M and the amount of glue dispensed by the dispensing machine in 5 seconds, the dispensing speed and running distance of the dispensing machine (equal to the product length), and adjust the position of the dispensing machine nozzle to be 4mm higher than the gap on the inner side of the molding groove.

[0050] D. First, turn off the "dispensing button" on the control panel, and let the dispensing nozzle travel along the edge of the silicone groove and the length of the product forward along the Y-axis. The setting is complete. Use the same method to set the start and end points of dispensing the other product. After all products are set, press the reset button and the dispensing nozzle will return to the machine origin.

[0051] E. Turn on the "Dispensing and Stirring" buttons on the device panel, press start, and begin dispensing the glue.

[0052] F. Remove from the mold after the adhesive has completely cured and dried.

[0053] The innovative features of this one-piece molded waterproof wall washer light are as follows:

[0054] In existing technologies, the process of potting wall washer lights involves attaching a light strip to a TPU or silicone base plate, applying adhesive, and then sealing the light strip with PU. The light strip and base plate are held together with 3M tape, without any glue. Furthermore, the TPU and silicone base plate are prone to peeling from the PU adhesive, easily losing their waterproof function. TPU is also hard and prone to yellowing. This innovative invention employs a one-piece, one-time potting process, encapsulating the light strip 360 degrees within the adhesive, achieving an IP68 waterproof effect. The finished product uses only one type of adhesive material. This invention's FPC outer coating structure uses a single material to create a unified structure, eliminating the need for a base plate and end caps.

[0055] The beneficial effects of this one-piece molded waterproof wall washer light are:

[0056] 1. The product has a waterproof rating of IP68, making it suitable for locations with high waterproofing requirements;

[0057] 2. The product is made in 15-meter sections, making installation convenient and saving on drive power.

[0058] 3. The product is transparent and clear, and the scissor position and electrical markings are visible, reducing the marking process;

[0059] 4. The product uses a single adhesive for 360-degree sealing, achieving IP68 waterproof rating.

[0060] 5. The plug for sealing the wires has been eliminated; the wires and lamp body are now encapsulated together with adhesive, resulting in better waterproofing and higher efficiency.

[0061] 6. The one-piece molded lens and adhesive are more firmly bonded and less prone to peeling, eliminating the risk of waterproofing failure due to lens and adhesive separation.

[0062] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
