Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures technology, and in particular to an AC wide-voltage waterproof lighting fixture. Background Technology

[0002] In power supply solutions for LEDs and related products, constant current power supply is undoubtedly an ideal choice. This power supply method can effectively avoid the current fluctuation problem caused by changes in the forward voltage of the LED, ensuring a constant current through the LED and thus achieving stable brightness output. Therefore, when designing existing LED driver circuits, in addition to meeting safety specifications, engineers will try their best to give the circuit constant current characteristics.

[0003] However, the mainstream LED constant current drive circuits on the market currently have some problems that urgently need to be solved. The main problem is that the physical components of the current LED constant current drive circuit cannot be waterproofed. During the operation of the LED constant current drive circuit, once water is immersed and interfered with, the entire circuit will be affected, making it difficult to truly achieve constant current output, resulting in a decrease in constant current output efficiency. At the same time, the installation and fixing of physical components is troublesome, requiring pre-prepared sheet metal at the installation location to facilitate the fixing of physical components. These factors, to some extent, limit the widespread application of LED technology in more fields. Utility Model Content

[0004] To address the technical problems of existing technologies where the physical components equipped with LED constant current drive circuits lack waterproofing and are difficult to install, this utility model provides a solution.

[0005] To achieve the above objectives, this utility model provides an AC wide-voltage waterproof lighting fixture, comprising:

[0006] The mounting base has a receiving groove on its first surface. The two sides of the receiving groove have inward folds, and a lamp panel is placed inside the groove. Multiple sets of LEDs are spaced apart on the lamp panel, and a covering layer is formed on the surface of the lamp panel to expose the LEDs. This covering layer fills the gap between the lamp panel and the inward folds, creating a seal. A circuit board is located at one end of the lamp panel and is electrically connected to it. The circuit board is covered by a protective cover, which snaps into the two inward folds. Plugs are located at both ends of the mounting base. The gap between the plugs and the mounting base is filled with a waterproof medium to form a first waterproof seal. The gap between the protective cover and the receiving groove is filled with a waterproof medium to form a second waterproof seal. The first and second waterproof seals are connected.

[0007] The locking block has a slot that matches the width of the mounting base. The locking block engages with the mounting base through the slot and is used to fix the mounting base to the wall.

[0009] As an improvement of this utility model, the bottom of the slot of the card block is provided with a through hole, and multiple first protrusions are arranged around the through hole. When the external stud passes through the through hole to fix the card block to the wall, a gap is left between the mounting base and the external stud.

[0010] As an improvement of this utility model, the bottom of the card block is provided with at least two rope holes, and the rope holes are located between the two first protrusions.

[0011] As an improvement of this utility model, the plug is provided with a mounting groove, and the two ends of the mounting base are embedded in the mounting groove to achieve connection with the plug.

[0012] As an improvement of this utility model, the mounting base is provided with heat dissipation through holes extending through both ends of the mounting base.

[0014] As an improvement of this utility model, the waterproof medium is a waterproof adhesive.

[0015] As an improvement of this utility model, the covering layer is made of glass glue.

[0016] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model provides an AC wide-voltage waterproof lamp, including a mounting base, a plug, and a locking block. The first side of the mounting base is provided with a receiving groove, and the two sides of the receiving groove form inward folds. A lamp plate is placed in the groove, and multiple sets of lamp beads are arranged at intervals on the lamp plate.

[0025] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0026] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0027] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0028] Please see Figures 1-5 This utility model discloses an AC-to-DC converter circuit, comprising AC power supply positive and negative terminals, a rectifier module, a main control chip, a filter module, a first resistor R1, a second resistor R2, and an inductor La. The AC power supply positive and negative terminals are coupled to the rectifier module, which converts AC current into DC current. The negative terminal of the rectifier module is grounded, and the positive terminal is connected to the filter module, the second pin of the main control chip, the second resistor R2, and the lamp board. Specifically, the lamp board is formed by combining a first lamp board L1, a second lamp board L2, and a third lamp board L3. The first pin of the main control chip is grounded. One end of the inductor La is coupled to the third pin of the main control chip, and the other end is coupled to the lamp board. One end of the first resistor R1 is coupled to the fourth pin of the main control chip, and the other end is grounded. Specifically, the main control chip is a KP1075X chip.

[0029] Unlike existing technologies, the positive terminal of the rectifier module is coupled to a filter module and a second resistor R2. This design, on the one hand, leverages the smoothing effect of the filter module on the current, combined with the synergistic regulation of the second resistor R2, to significantly improve the stability of the output current and effectively suppress the impact of current fluctuations on subsequent circuit components. On the other hand, it abandons the complex and redundant traditional connection structure, simplifying the circuit layout with a simple coupling method, reducing the number of components used, and reducing hardware costs and production assembly difficulty while ensuring circuit performance, thus achieving a dual optimization of performance improvement and cost control.

[0030] In this embodiment, the rectifier module is a rectifier bridge composed of four diodes. Its AC input terminal is connected to the positive and negative terminals of the AC power supply to convert AC power into pulsating DC power. The negative terminal of the rectifier bridge is directly grounded, and the positive terminal is connected to the positive terminal of the filter module, the second pin of the main control chip, the second resistor R2, and the lamp board, respectively.

[0031] In this embodiment, the filtering module is a polarized capacitor C, which is used as a filtering element. Its positive terminal is connected to the output of the rectifier bridge, and its negative terminal is grounded. It is used to smooth the voltage waveform after rectification and reduce the ripple coefficient.

[0032] This utility model also provides an AC wide-voltage waterproof lamp containing the above-mentioned AC to constant DC circuit, including a mounting base 1, a plug 4, and a locking block 6. The first surface of the mounting base 1 is provided with a receiving groove 2, and the two sides of the receiving groove 2 form inward folds 21. A lamp plate 7 is placed inside the groove. Multiple sets of lamp beads 71 ​​are also arranged at intervals on the lamp plate 7, and a covering layer 72 is formed on the surface of the lamp plate 7 to expose the lamp beads 71. The covering layer 72 fills the gap between the lamp plate 7 and the inward folds 21 to form a sealed state. A circuit board is provided at one end of the lamp plate 7, and the circuit board is electrically connected to the lamp plate 7. The circuit board is covered by a protective cover 5, which snaps into the inner folds 21 on both sides. Plugs 4 are located at both ends of the mounting base 1, and the gap between the plugs 4 and the mounting base 1 is filled with a waterproof medium to form a first waterproof seal. The gap between the protective cover 5 and the receiving groove 2 is filled with a waterproof medium to form a second waterproof seal, and the first and second waterproof seals are connected. A locking block 6 has a slot 61 adapted to the width of the mounting base 1, and the locking block 6 engages with the mounting base 1 through the slot 61, thus fixing the mounting base 1 to the wall. Specifically, the waterproof medium is waterproof adhesive, and the covering layer 72 is coated with silicone sealant. The locking block 6 has a slot 61 adapted to the width of the mounting base 1, and the locking block 6 engages with the mounting base 1 through the slot 61, thus fixing the mounting base 1 to the wall. Specifically, the protective cover 5 has a protrusion that engages with the inner fold 21 of the receiving groove 2. The plug 4 is provided with a mounting groove 41 that matches the shape and size of the end of the mounting base 1, and the mounting base 1 can be directly embedded into the mounting groove 41 to achieve connection.

[0033] Specifically, the protective cover 5 covers the circuit board, giving it dustproof and waterproof functions. The protective cover 5 has a notch near the plug 4 for wires to pass through. The plug 4 has a channel 42 near the side of the circuit board, through which the wires connected to the circuit board can extend smoothly to the outside. This effectively avoids damage to the wires caused by external friction or squeezing during the wire exit process, thus improving the service life and safety of the wires.

[0034] In practical use, the mounting base 1 is made of aluminum profile, a material that offers significant advantages in addressing the heat dissipation issue of the lamp panel 7. Aluminum profiles have excellent thermal conductivity, significantly higher than many common materials. When the lamp panel 7 generates heat during operation, the aluminum profile quickly absorbs the heat and conducts it rapidly to the surface through its structure. Due to the large surface area of ​​the aluminum profile, heat can come into contact with the surrounding air over a large area, thus forming natural convection. Hot air rises, and cool air replenishes, creating a continuous circulation that carries away and dissipates the heat generated by the lamp panel 7 into the surrounding environment, effectively reducing the operating temperature of the lamp panel 7, ensuring its stable operation, and extending its service life.

[0035] In this embodiment, the bottom of the slot of the locking block 6 is provided with multiple first protrusions 64, and the two opposite walls of the slot 61 are provided with second protrusions 65. The first protrusions 64 and second protrusions 65 abut against the mounting base 1. The bottom of the slot of the locking block 6 is provided with a through hole 62, and the multiple first protrusions 64 are arranged around the through hole 62. When the slot 61 is fixed to the wall by using an external stud through the through hole 62, the mounting base 1 does not contact the external stud. In practical applications, if it is necessary to fix the locking block 6 to the wall, the locking block 6 can be firmly fixed to the wall surface by using an external stud through the through hole 62. Since the mounting base 1 is made of conductive aluminum profile material, the first protrusions 64 and second protrusions 65 are provided to engage the mounting base 1, which can effectively avoid direct contact between the mounting base 1 and the stud, thereby reducing the risk of electrical conductivity. In practical applications, the locking block 6 may also be fixed to an outdoor post. In this case, a rope can be threaded through a pre-set rope hole 63, located between the two first protrusions 64, to securely bind it to the outdoor post for stable fixation. The second protrusion 65 has a protrusion located away from and parallel to the first protrusion 64, with a through hole 66. In practical applications, an external stud can also be used to fix the locking block 6 to the wall by threading it through the through hole 66.

[0036] The side of the second protrusion 65 away from the first protrusion 64 is a guide slope, and the two opposing guide slopes are used to guide the mounting base 1 into the slot 61. When the mounting base 1 is inserted into the slot 61, the second protrusion 65, which is inclined towards the slot 61, can effectively reduce the contact area with the mounting base 1, thereby preventing the mounting base 1 from being damaged.

[0037] In this embodiment, the mounting base 1 is provided with heat dissipation holes 3 extending through both ends of the mounting base 1. Specifically, when the lamp board 7 in the receiving groove 2 is working, it will generate heat, and the heat dissipation holes 3 can effectively help dissipate heat, ensuring that the lamp board 7 is always within a suitable operating temperature range, maintaining its normal operation, and effectively avoiding problems such as accelerated aging and damage of the lamp beads 71 ​​due to excessive temperature, or affecting the light-emitting performance of the lamp board 7.

[0038] The advantages of this utility model are:

[0039] 1. The fourth pin of the main control chip of this utility model is coupled to the first resistor to prevent the main control chip from being damaged by overcurrent. The positive terminal of the rectifier module is coupled to the second resistor, which can limit the branch current and keep the voltage and current of each part within a suitable range, ensuring the stable operation of the main control chip and avoiding damage to the device due to abnormal voltage and current.

[0040] 2. The AC wide-pressure waterproof lamp of this utility model provides waterproofing for the internal lamp panel and also has heat dissipation holes to effectively reduce the working temperature of the lamp panel, ensure stable operation of the lamp panel, and extend its service life.

[0041] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
