Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Existing LED circuit boards are integrated with LED light sources on their surfaces. The LED light sources emit heat when in use, which can easily damage components inside the LED circuit boards. In addition, most LED circuit boards are embedded, and when inspected or replaced, the surface of the LED circuit boards is smooth, making them inconvenient to remove. In addition, the internal space of the LED circuit boards is compact, and they can easily break and be damaged when impacted or vibrated. To solve the above problems, a heat conduction device for LED circuit boards is needed.

The coordinated use of the heat dissipating plate 201, the heat conducting pipe 202 and the heat dissipating fins 203 greatly increases the heat conduction effect of the device.

[0026] See also Figure 1-5A heat conduction device for an LED circuit board, wherein a pick-up mechanism 3 is installed on the inner wall of a circuit board body 1, and the pick-up mechanism 3 comprises a card board 301, a buckle groove 302 and a lifting block 303. A card board 301 is installed on the inner wall of the circuit board body 1, and a buckle groove 302 is opened on the inner wall of the circuit board body 1.

[0028] Working principle: When in use, first move the device to the desired position, and then when the LED light source on the surface of the circuit board body 1 lights up, heat is generated, which can easily damage the internal components of the circuit board body 1. The heat pipe 202 is hollow inside, and the air will conduct heat when passing through the inside of the heat pipe 202. The setting of the heat sink 203 increases the contact area between the heat pipe 202 and the air. The coordinated use of the heat sink 201, the heat pipe 202 and the heat sink 203 greatly increases the thermal conductivity of the device. In addition, since the internal space of the circuit board body 1 is limited when the circuit board body 1 is installed, when the circuit board body 1 is stationary, the lifting block 303 shrinks to the inside of the circuit board body 1 due to gravity, and the top of the lifting block 303 is aligned with the top of the circuit board body 1.

Finally, when the circuit board body 1 is easily impacted or violently vibrated during installation or use, causing damage to internal components, the setting of the limit block 403 can absorb the external force through the buffer spring 402, avoiding the circuit board body 1 from breaking or internal components from being damaged, and extending the service life of the device.
