Technical Field

[0001] The utility model relates to the technical field of LED driving power supplies, in particular to an LED driving power supply with high efficiency in heat dissipation. Background Art

[0002] With the development and progress of science and technology, traditional lighting fixtures are also being upgraded and replaced. Lighting lamps are upgraded from incandescent lamps to fluorescent lamps, and then from fluorescent lamps to LED lamps, and from high-energy-consuming and low-brightness lamps to low-power and high-brightness cold light sources. With the continuous development of LED technology, the brightness and color of LEDs are also constantly improving. At the same time, since LEDs are cold light sources and do not generate heat, they are relatively safe, and their costs are constantly decreasing and their lifespan is constantly increasing. Now, LED lamps have become a widely used type of lamp, but LEDs need to convert the mains power when in use. The mains power is converted into the voltage required by the LED through conversion, but the LED driver power supply will generate a lot of heat when in use. If the LED driver power supply is not cooled, the life of the parts in the LED driver power supply will be greatly shortened. For this reason, the LED driver power supply needs to be cooled to increase the service life of the power supply. Utility Model Content

[0003] The utility model aims to provide an LED driving power supply with high efficiency in heat dissipation, so as to solve the problem in the above background technology that the LED driving power supply generates heat and shortens its life.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an LED driving power supply with high efficiency in heat dissipation, comprising an aluminum base plate, an outer surface of which is fixedly mounted with an oblique buckle, and an end of the oblique buckle away from the aluminum base plate is provided with a wedge-shaped block, and an outer surface of the oblique buckle is provided with a groove, side slots are provided on the outer surfaces of both sides of the aluminum base plate, and a protective shell is inserted into the inside of the side slot, through holes are provided at both ends of the aluminum base plate, and the outer surface of the aluminum base plate is fitted with the iron shell base inside the lampshade, and a heat dissipation mechanism is provided on the side surface of one end of the aluminum base plate close to the oblique buckle, and the temperature of the components is reduced by the heat dissipation mechanism to increase the service life of the LED driving power supply.

[0006] By adopting the above technical solution, the heat dissipation film is passed through the oblique buckle to make the side surface of the heat dissipation film fit with the outer surface of the aluminum base plate, and the outer surface of the heat dissipation film fits with the outer surface of the PCB substrate. The insulation of the heat dissipation film prevents the PCB substrate and the aluminum base plate from short-circuiting. At the same time, the heat dissipation film is used to introduce heat into the aluminum base plate, so that the lamp base in contact with the aluminum base plate absorbs heat, thereby increasing the heat dissipation area and improving the heat dissipation effect and speed of the PCB substrate.

[0007] Preferably, a heat sink is fixedly mounted on the outer surface of the PCB substrate, and the heat sink is in contact with the heat generating components on the outer surface of the PCB substrate, and input and output wires are welded and mounted on both sides of the PCB substrate, the heat sink is designed in a mountain shape, and the heat generating components of the PCB substrate are fixed inside the heat sink, and a cooling fan is fixedly mounted on one end of the PCB substrate close to the heat sink.

[0008] By adopting the above technical solution, external air can be drawn into the LED driver power supply through the cooling fan, so that the drawn air passes through the heat sink, and the heat generated by the heating parts is absorbed by the heat sink, thereby improving the heat dissipation effect of the PCB substrate and the service life of the LED driver power supply.

[0009] Preferably, a clamping mechanism is provided at one end of the aluminum base plate close to the heat sink, and the clamping mechanism facilitates air to pass through the PCB substrate, thereby protecting electronic components in the PCB substrate.

[0010] By adopting the above technical solution, the PCB substrate can be protected to prevent the electronic components in the PCB substrate from being damaged, and at the same time, the assembly of the LED driving power supply is convenient.

[0011] Preferably, the locking mechanism includes: a protective shell, both ends of which are inserted into the side slot, and a locking slot is provided on the outer surface of the side slot, buckles are fixedly provided on the inner surfaces of both sides of the protective shell close to the side slot, and the buckles are engaged with the slots, and strip grooves are evenly provided on the side surfaces of both ends of the protective shell.

[0012] By adopting the above technical solution, the protective shell can be fixed to the outer surface of the aluminum base plate through the side slots and the card slots, and the protective shell can be limited by the heat dissipation film and the PCB substrate, which makes it convenient to install the protective shell and to pry up the protective shell and take out the PCB substrate for maintenance.

[0013] Preferably, sliding suction structures are provided at both ends of the aluminum base plate, and the aluminum base plate can be adsorbed inside the lamp base through the sliding suction structures.

[0014] By adopting the above technical solution, the aluminum base plate can be fixed and adsorbed inside the lamp base through a strong magnet.

[0015] Preferably, the sliding suction structure includes: a downward pressing horizontal bar, which is slidably installed on both sides of the aluminum base plate, and a strong magnet is fixedly installed on one end of the downward pressing horizontal bar located inside the aluminum base plate, and side sliding columns are fixedly installed on the outer surfaces of both ends of the downward pressing horizontal bar close to the strong magnet, and a lifting platform is fixedly installed on the outer surfaces of both ends of the aluminum base plate, and circular grooves are evenly arranged on the outer surface of the lifting platform, a pulling block is rotatably installed on the outer surface of the aluminum base plate, and the outer surface of the pulling block is in contact with the outer surface of the side sliding column, the circular groove of the lifting platform is passed through by the input and output wires, and the outer surfaces of the input and output wires are respectively in contact with the outer surfaces of the lifting platform and the downward pressing horizontal bar.

[0016] By adopting the above technical scheme, a strong magnet can be adsorbed on the inside of the lamp base, and the strong magnet can drive the downward pressure bar to clamp the input and output wires with the lifting platform to prevent the input and output wires from moving and enhance the tensile strength of the input and output wires. At the same time, the side sliding column can be lifted up by the lever block so that the downward pressure bar uses the aluminum base plate as a fulcrum to pull up the strong magnet and separate it from the outer surface of the lamp base, thereby enhancing the tensile strength of the input and output wires and facilitating the separation of the strong magnet from the lamp base.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the LED driving power supply with high efficiency heat dissipation:

[0018] 1. Insert the heat dissipation film into the bevel buckle so that the side surface of the heat dissipation film is in close contact with the side surface of the aluminum base plate, and then insert the PCB substrate into the bevel buckle. Through the elastic contraction of the bevel buckle, the PCB substrate is fixed through the bevel buckle so that the PCB substrate is in close contact with the heat dissipation film. When the LED driving power source generates heat, the PCB substrate will transfer the heat to the aluminum base plate through the heat dissipation film, and the aluminum base plate fits with the iron base of the lamp, transferring the heat to the iron base of the lamp, thus expanding the heat dissipation area of ​​the PCB substrate and improving the heat dissipation efficiency.

[0019] 2. As the LED driver power is powered on, the cooling fan will be powered on and rotated, so that the seriously heated electronic parts on the PCB substrate can be cooled down through the heat absorption of the heat sink. As the cooling fan rotates, air is drawn in and discharged from the gaps in the protective shell, cooling down the parts on the PCB substrate as a whole and taking away the heat. The protective shell can also be pried off to disengage the card slot and the buckle, making it convenient to remove the PCB substrate for maintenance, thereby increasing the service life of the electronic components on the PCB substrate and extending the service life of the LED driver power supply.

[0020] 3. After the input and output wires of the LED driving power supply are connected to the mains and the lamp, the aluminum base plate can be attached to the metal lamp holder so that the strong magnet is adsorbed on the metal lamp holder through magnetic force, driving the downward pressure bar to move. The input and output wires are clamped by the lifting platform and the downward pressure bar to fix the input and output wires to prevent the input and output wires from moving and improve the tensile strength of the input and output wires. At the same time, the aluminum base plate can be close to the metal lamp holder. When the aluminum base plate needs to be removed, it is only necessary to rotate the lever block so that the lever block supports the side sliding column to separate the strong magnet from the metal lamp holder, which is convenient for fixing the input and output wires and improving the tensile strength, and the strong magnet can be easily separated from the metal lamp holder.
