Description

Technical Field

[0001] This utility model relates to the field of driving power supply technology, and in particular to an intelligent regulated LED driving power supply. Background Technology

[0002] With the popularization of LED lighting technology, its advantages such as energy saving, long life and environmental protection have been widely recognized. However, LED lamps have put forward higher requirements for the stability, efficiency and intelligent control of power supply. Intelligent regulated LED driver power supply is a power conversion device designed specifically for LED light source. Its core function is to convert the input power supply into the stable DC voltage or current required by LED.

[0003] However, existing intelligent regulated LED driver power supplies have the following drawbacks:

[0004] (1) When traditional LED driver power supplies work for a long time, the heat generated by the heating element is difficult to dissipate quickly, which affects the accuracy and stability of voltage regulation control. At the same time, electromagnetic interference will affect the signal processing accuracy of the main control chip.

[0005] (2) When traditional LED driver power supplies are subjected to external vibration or impact, the circuit board is easily damaged due to rigid connection, the solder joints loosen or even fall off, and humid air or liquid can easily enter the power supply, affecting the normal operation of the power supply.

[0006] Therefore, this utility model provides an intelligent regulated LED driver power supply. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The problem solved by this utility model is to provide a highly practical intelligent regulated LED driver power supply, which solves the problems mentioned in the background art, such as the difficulty in quickly dissipating the heat generated by the heating element and the easy damage to the circuit board due to rigid connection.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: an intelligent regulated LED driver power supply, comprising an upper housing, a lower housing, and a circuit board. An inverted T-shaped heat-conducting column is installed on the inner top wall of the upper housing. The bottom of the inverted T-shaped heat-conducting column is attached to the heating element on the top of the circuit board via thermally conductive silicone. An annular groove is formed on the inner side wall of the lower housing, and a moisture-proof sealing ring is installed on the inner side wall of the annular groove. An anti-vibration spring column is fixedly connected to the edge of the bottom of the circuit board, and the bottom of the anti-vibration spring column is fixedly connected to the top of the boss on the lower housing. The upper housing and the lower housing are connected on both sides by screws. Multiple countersunk holes adapted to the screws are formed on both sides of the lower housing. A washer is fitted onto the surface of the screw, and one side of the washer contacts the inner side wall of the countersunk hole. Multiple threaded holes adapted to the screws are formed on both sides of the upper housing.

[0011] Optionally, the top of the upper housing is arrayed with heat dissipation fins, which are fixedly connected to the top of the inverted T-shaped heat conduction pillars. The inverted T-shaped heat conduction pillars quickly conduct heat from the heat-generating components of the circuit board to the heat dissipation fins, and the heat is dissipated more quickly through air convection, which can effectively reduce the temperature of the internal components.

[0012] Optionally, an insulating partition is fixedly connected to the upper surface of the circuit board. The top of the insulating partition is in contact with the inner top wall of the upper housing. The insulating partition can effectively separate the high-voltage and low-voltage areas on the circuit board and reduce electromagnetic interference.

[0013] Optionally, mounting grooves are provided on both sides of the upper and lower housings. A waterproof sleeve is provided on the inner wall of the mounting groove. The inner wall of the waterproof sleeve is provided with a spiral anti-slip texture. When an external cable passes through, the waterproof sleeve can fit tightly against the surface of the cable, effectively preventing moisture, dust and other contaminants from entering the power supply.

[0014] Optionally, a mounting plate is fixedly connected to the bottom of the lower housing. The top of the mounting plate has multiple mounting holes, which facilitates the use of bolts and other connecting parts to install and fix the drive power supply in various locations such as walls and equipment brackets.

[0015] Optionally, an anti-slip pad is fixedly connected to the bottom of the mounting plate. The bottom of the anti-slip pad has anti-slip texture. The anti-slip pad can increase the friction between the pad and the contact surface and prevent the power supply from sliding.

[0016] (III) Beneficial Effects

[0017] This utility model provides an intelligent regulated LED driver power supply, which has the following beneficial effects:

[0018] 1. This intelligent voltage-regulated LED driver power supply uses a design where the heat-generating components on the circuit board are bonded to inverted T-shaped heat-conducting pillars via thermally conductive silicone, and the heat is conducted to the top heat sink fins. This design greatly improves heat dissipation efficiency, prevents component performance degradation due to high temperatures, ensures stable voltage regulation, and separates high-voltage and low-voltage areas with an insulating partition to reduce electromagnetic interference and improve the signal processing accuracy of the main control chip and the reliability of voltage regulation.

[0019] 2. This intelligent voltage-stabilized LED driver power supply features an elastic support system where the bottom edge of the circuit board is connected to the lower housing boss via anti-vibration spring columns. This system effectively absorbs external vibration or impact energy, protecting the circuit board.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4This utility model provides a technical solution: an intelligent regulated LED driver power supply, including an upper housing 1, a lower housing 2, and a circuit board 3. An inverted T-shaped heat-conducting column 4 is installed on the inner top wall of the upper housing 1. The bottom of the inverted T-shaped heat-conducting column 4 is bonded to the heating element on the top of the circuit board 3 via thermally conductive silicone 5. The inverted T-shaped heat-conducting column 4 directly connects the upper housing 1 and the heating element of the circuit board 3. The thermally conductive silicone 5 fills the tiny gaps between them, significantly reducing thermal resistance. An annular groove is formed on the inner side wall of the lower housing 2, and a moisture-proof sealing ring 6 is installed on the inner side wall of the annular groove to form a waterproof and dustproof barrier. The bottom of the circuit board 3... The edge of the part is fixedly connected with an anti-vibration spring column 7. The anti-vibration spring column 7 adopts a high-strength spring and rubber buffer structure, which absorbs vibration energy through compression or stretching deformation to avoid rigid collision between the circuit board 3 and the shell. The bottom of the anti-vibration spring column 7 is fixedly connected to the top of the boss of the lower shell 2. The upper shell 1 and the lower shell 2 are connected by screws 8 on both sides. Multiple countersunk holes adapted to screws 8 are opened on both sides of the lower shell 2. A washer 12 is fitted on the surface of the screw 8. One side of the washer 12 contacts the inner wall of the countersunk hole. Multiple threaded holes adapted to screws 8 are opened on both sides of the upper shell 1.

[0027] The top of the upper housing 1 is arrayed with heat dissipation fins 9, which are fixedly connected to the top of the inverted T-shaped heat conduction pillar 4. The inverted T-shaped heat conduction pillar 4 quickly conducts the heat of the heat-generating element of the circuit board 3 to the heat dissipation fins 9, and accelerates heat dissipation through air convection, which can effectively reduce the temperature of the internal components.

[0028] An insulating partition 10 is fixedly connected to the upper surface of the circuit board 3. The top of the insulating partition 10 is in contact with the inner top wall of the upper housing 1. The insulating partition 10 can effectively separate the high voltage and low voltage areas on the circuit board 3 and reduce electromagnetic interference.

[0029] Both sides of the upper housing 1 and the lower housing 2 are provided with mounting grooves. The inner side wall of the mounting groove is provided with a waterproof rubber sleeve 11. The inner side wall of the waterproof rubber sleeve 11 is provided with a spiral anti-slip texture. When the external cable passes through, the waterproof rubber sleeve 11 can fit tightly against the surface of the cable, effectively preventing moisture, dust and other substances from entering the power supply.

[0030] The bottom of the lower housing 2 is fixedly connected to a mounting plate 13. The top of the mounting plate 13 has multiple mounting holes. The mounting plate 13 facilitates the use of bolts and other connecting parts to install and fix the drive power supply in various locations such as walls and equipment brackets.

[0031] An anti-slip pad 14 is fixedly connected to the bottom of the mounting plate 13. The bottom of the anti-slip pad 14 has anti-slip texture. The anti-slip pad 14 can increase the friction between itself and the contact surface and prevent the power supply from sliding.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: The heat-generating components on the circuit board 3 are bonded to the inverted T-shaped heat-conducting pillars 4 through the thermally conductive silicone 5. The heat is conducted to the top heat dissipation fins 9 through the inverted T-shaped heat-conducting pillars 4 and dissipated quickly through air convection. This prevents the components from drifting due to high temperature and ensures the stability of voltage regulation control. The insulating partition 10 separates the high-voltage and low-voltage areas on the circuit board 3 to prevent electromagnetic interference from affecting the signal processing accuracy of the main control chip and further improve the reliability of voltage regulation control.

[0034] The second step: The bottom edge of the circuit board 3 is connected to the boss of the lower housing 2 through multiple sets of anti-vibration spring columns 7 to form an elastic support system. When the power supply is subjected to external vibration or impact, the anti-vibration spring columns 7 absorb energy through compression or stretching deformation, reducing the direct impact of vibration on the circuit board 3. The annular groove on the inner wall of the lower housing 2 is embedded with a moisture-proof sealing ring 6. When the upper housing 1 and the lower housing 2 are fastened by screws 8, the moisture-proof sealing ring 6 is squeezed to fill the gap between the housings, forming a physical sealing barrier to prevent humid air or liquid from entering the interior.
