Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting, and in particular to an injection-molded integrated waterproof light strip. Background Technology
[0002] Lighting is essential in both indoor and outdoor environments. LED light sources have seen widespread adoption in recent years due to their significant advantages such as energy saving, high efficiency, and environmental friendliness. However, LED light source boards are susceptible to leakage. Inadequate insulation design, scratches, or damage to the insulation layer can lead to current leakage. Over time, the insulation material may age and fail, causing leakage. Excessive current or voltage fluctuations can damage electronic components, resulting in leakage.
[0003] The LED light source board is installed inside the lamp housing. Because the LED light source board is installed directly against the lamp housing, and the lamp housing is mostly made of conductive metal, if the LED light source board leaks current, it will be conducted to the lamp housing. Since the lamp housing is exposed, people who touch the lamp housing will suffer electric shock. The LED light source board consists of LED chips and a substrate. The LED chips are attached to the substrate and are exposed without protection, making them easily damaged.
[0004] Therefore, how to protect light sources and improve their safety performance is a technical problem that urgently needs to be solved. Utility Model Content
[0005] The main purpose of this utility model is to provide an injection-molded integrated waterproof light strip, which aims to protect the light source and improve its safety performance.
[0006] This utility model proposes an injection-molded integrated waterproof light strip, including an LED light source board, an LED lens bonded to the LED light source board, and an insulating protective shell that adheres to and wraps the LED light source board. The LED lens is bonded to the LED light source board with insulating sealant, covering the LED beads inside. The insulating protective shell has a bead hole for the LED lens on the LED light source board to expose the bead.
[0007] Preferably, the bottom outer edge of the LED lens is surrounded by a skirt.
[0008] Preferably, the width of the skirt hem is 1.0 mm or more.
[0009] Preferably, a raised ring is provided on the insulating protective shell around the skirt edge, the ring enclosing the skirt edge.
[0010] Preferably, the insulating protective shell is made of plastic and is directly molded onto the LED light source board.
[0011] Preferably, the insulating protective shell is made of flame-retardant plastic.
[0012] Preferably, the outer diameter of the LED lens matches the diameter of the lamp bead hole, and the LED lens fills the lamp bead hole.
[0013] Preferably, the LED light source board has a driving circuit, and the insulating protective shell has component holes for exposing the components of the driving circuit.
[0014] Preferably, the insulating protective shell has a frame that surrounds the components of the driving circuit.
[0015] Preferably, the front and / or back of the insulating protective shell have perforations, and waterproof ink is sprayed onto the portion of the LED light source board exposed through the perforations.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This utility model proposes an integrated waterproof LED strip comprising an LED light source board and an insulating protective shell tightly encasing the LED light source board. An LED lens is bonded to the LED light source board with insulating sealant, housing the LED beads within it. The insulating protective shell has LED bead holes for exposing the LED beads and LED lens on the LED light source board. The insulating protective shell protects the LED light source board, and the LED lens protects the LED beads, preventing wear and tear on the LED light source board. This improves the lifespan and performance stability of the LED light source board.
[0018] The insulating protective shell and LED lens can effectively isolate current, ensuring that even if leakage occurs inside the LED light source board, the current will not escape to the outside, ensuring that it will not conduct electricity to the lamp housing and guaranteeing the safety of the operating environment.
[0019] The design of the LED lens prevents dust and moisture from interfering with the LED chips, further maintaining the electrical performance of the light source. It replaces potting compound in LED lenses, facilitating installation.
[0020] A raised ring is provided around the edge of the skirt, which wraps around the skirt of the LED lens 2 for a stronger seal. Attached Figure Description

[0027] Reference Figure 1 and Figure 2 This utility model embodiment provides an injection-molded integrated waterproof light strip:
[0028] An injection-molded integrated waterproof light strip includes an LED light source board and an insulating protective shell 1 that adheres to and wraps around the LED light source board. An LED lens 2 is installed on the LED beads. The LED lens 2 is bonded to the LED light source board with insulating sealant and covers the LED beads 20 inside. The steps for installing the LED lens 2 are as follows: apply adhesive around the LED beads 20 in a circular motion, and then bond the LED lens 2.
[0029] The insulating protective shell 1 has LED bead holes 11 for exposing the LED beads 20 and LED lens 2 on the LED light source board. The insulating protective shell 1 is made of flame-retardant plastic and is directly plasticized and molded on the LED light source board by hot melt plasticizing to form an insulating protective shell that tightly wraps the LED light source board inside.
[0030] The LED light source board has a driving circuit, and the insulating protective shell 1 has component holes 13 for exposing the components of the driving circuit. A frame is provided around the edge of the component holes 13; for components with a certain height, the frame protects the component. For thin components, such as surface-mount diodes, the frame is not required. The top of the frame is designed to be open to facilitate heat dissipation of the driving circuit. To further protect the driving circuit, thermally conductive potting compound can be filled into the component holes 13 to cover the driving circuit.
[0031] The LED light source board has a wire bonding section, and the insulating protective shell 1 has a wire bonding position for the wire bonding section to be exposed. The edge of the wire bonding position is surrounded by a frame. After the wire is bonded at the wire bonding position, waterproof glue is dripped in to further improve the safety performance.
[0032] The light emitted by the LED chip 20 is emitted through the LED lens 2. The insulating protective shell 1 protects the LED light source board, and the LED lens 2 protects the LED chip 20 from wear. This improves the lifespan and performance stability of the LED light source board. The insulating protective shell 1 and LED lens 2 effectively isolate current, ensuring that even if leakage occurs inside the LED light source board, the current will not escape to the outside, preventing conductivity to the lamp housing and ensuring the safety of the operating environment.
[0033] The bottom outer edge of the LED lens 2 is surrounded by a skirt 21 with a width of 1.0mm or more. This increases the bonding area of the part of the LED lens 2 surrounding the LED bead 20, preventing moisture from entering the inner cavity of the LED lens 2 and improving its waterproof performance.
[0034] The outer diameter of the LED lens 2 matches the diameter of the LED bead hole 11, and the LED lens 2 fills the LED bead hole 11. A raised retaining ring 12 is provided around the skirt 21 on the insulating protective shell 1, which not only protects the LED lens 2, but also wraps the skirt of the LED lens 2 with the retaining ring 12, so as to enhance the sealing performance.
[0035] The insulating protective shell 1 has connection holes for screw connection. Both ends of the insulating protective shell 1 are longer than the LED light source board. The connection holes are located at both ends of the insulating protective shell 1 and are outside the ends of the LED light source board. The connection holes are not related to the LED light source board. The LED light source structure is installed inside the lamp housing or other accessories that require installation through the connection holes.
[0036] In a preferred embodiment, the front and / or back of the insulating protective shell have perforations for heat dissipation of the LED light source board. These perforations are not located on the easily worn sides of the LED light source board. Even with perforations, when the LED light source structure is installed inside the lamp housing, the insulating protective shell still separates the LED light source board from the lamp housing, preventing leakage. The easily worn sides of the LED light source board are still protected.
[0037] Waterproof ink is sprayed onto the exposed parts of the LED light source board through the cutout holes to further improve electrical safety.
[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art can still combine, add, delete, or otherwise adjust the features of the various embodiments of this utility model according to the circumstances without conflict or creative effort, thereby obtaining different technical solutions that do not fundamentally depart from the concept of this utility model.
