Description

Technical Field

[0002] LED lamp is a piece of electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire, and sealed with epoxy resin around to protect the internal core wire. The LED lamp power supply is a device that provides power to the LED lamp, also known as the LED power supply, which provides the power required by all components in the LED lamp. By placing the power box externally, the weight and heat of the LED lamp itself can be greatly reduced, making it easy to install and ensuring the heat dissipation effect of the lamp.

[0003] However, when the power supply of the LED lamp is external, it needs to dissipate heat, so a heat dissipation hole is opened on the power supply housing. However, after the LED lamp is used, the heat dissipation hole is still open, which makes it easy for dust to enter the heat dissipation hole, blocking the heat dissipation hole and affecting heat dissipation, and even enter the power supply housing and attach to the circuit board to affect the use of the power supply. After the LED lamp is used, dust is also easy to enter the power slot of the power supply housing used to connect the LED lamp, affecting the connection and use of the power supply. For this reason, we have designed an LED lamp power supply device to solve the above problems. Utility Model Content

[0021] The side wall of the power supply housing 1 is fixedly connected with a protective component that covers the outside of the power supply slot. The protective component includes an annular cover shell 5 that is fixedly connected to the side wall of the power supply housing 1 and covers the outside of the power supply slot. The side wall of the power supply housing 1 is fixedly connected with a support plate 6. Two slide bars 7 are slidably connected through the support plate 6. The bottoms of the two slide bars 7 are commonly fixedly connected with a baffle 8 that abuts against the side wall of the annular cover shell 5. When the baffle 8 is opposite to the annular cover shell 5, it can block the power supply slot to prevent dust from entering the power supply slot. The upper ends of the two slide bars 7 are commonly fixedly connected with a pull plate 9. A plurality of springs 10 are connected between the pull plate 9 and the upper end of the support plate 6. The spring 10 is a tension spring. In a natural state, the pull plate 9 can be pulled downward, so that the slide bar 7 drives the baffle 8 to move downward to block the annular cover shell 5.

[0022] The front and rear side walls of the power supply housing 1 are penetrated with a plurality of heat dissipation holes, and the front and rear side walls of the power supply housing 1 are provided with dust-proof heat dissipation components opposite to the heat dissipation holes, and the dust-proof heat dissipation components include two first plug shells 11 and two second plug shells 4 fixedly connected to the side walls of the power supply housing 1 and arranged on the left and right, and the two first plug shells 11 and the two second plug shells 4 are slidably connected with plug rods 12, and the side walls opposite to the plurality of plug rods 12 are commonly fixedly connected with a dustproof plate 13, and the dustproof plate 13 is fitted with the side wall of the power supply housing 1, and the dustproof plate 13 is penetrated with a plurality of through openings 14 opposite to the heat dissipation holes, and dustproof nets are installed in the plurality of through openings 14, and when the through openings 14 are opposite to the heat dissipation holes on the power supply housing 1, air can circulate between the inside of the power supply housing 1 and the outside world, and the inside of the power supply housing 1 is cooled, and the provision of the dustproof net can reduce the dust from entering the power supply housing 1;

[0023] The side walls of the first plug shell 11 and the second plug shell 4 are both provided with a socket, and the plug rod 12 is slidably connected in the socket.

At this time, the plug rod 12 in the first plug shell 11 is away from the inner wall of the first plug shell 11, and the second magnetic block on the plug rod 12 and the first magnetic block in the first plug shell 11 will not be attracted to each other. At this time, the through hole 14 on the dustproof plate 13 is opposite to the heat dissipation hole on the power supply housing 1, so that the air inside and outside the power supply housing 1 can circulate to dissipate the heat inside the power supply housing 1, and the setting of the dustproof net can reduce the dust from entering the power supply housing 1.

[0027] When the LED lamp is pulled out of the power slot after use, the spring 10 can pull the pull plate 9 downward, so that the baffle 8 is opposite to the annular cover 5, and the annular cover 5 is blocked to prevent dust from entering the power slot, thereby preventing the LED lamp from having poor contact with the power slot during subsequent use;

[0028] Pull the dustproof plate 13 to move it toward the first plug shell 11 until the second magnetic block on the plug rod 12 in the first plug shell 11 contacts the first magnetic block in the first plug shell 11 to fix the dustproof plate 13. At this time, the plug rod 12 in the second plug shell 4 is away from the inner wall of the second plug shell 4, and the second magnetic block on the plug rod 12 and the first magnetic block in the second plug shell 4 will not be attracted to each other. At this time, the through hole 14 on the dustproof plate 13 is misaligned with the heat dissipation hole on the power supply housing 1, and the dustproof plate 13 can block the heat dissipation hole to prevent dust from entering the heat dissipation hole and entering the power supply housing 1 through the heat dissipation hole.
