Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp board structural accessories, in particular to a heat dissipation type LED lamp board structure. Background Art

[0002] The LED light board is a medium that supports the lamp beads and allows the LED lamp beads to be welded. The surface of the light board is not only connected to the lamp beads, but also has capacitors and other devices installed. The electronic equipment connected to the circuit board and the capacitors on the circuit board will generate heat when working, causing the internal temperature of the equipment to rise rapidly. The direct cause of the temperature rise of the circuit board is the existence of circuit power consumption devices. Electronic devices all have power consumption to varying degrees, and the heat intensity varies with the power consumption. In addition, because only about 30% of the electrical energy of the LED light source is converted into light energy, the rest of the energy will be converted into heat energy and must be transmitted by heat conduction. In this case, the LED light board and the electronic devices on the light board will naturally emit high temperatures. If these higher temperatures are not dissipated in time, the LED lamp equipment will continue to heat up, and the devices on the light board will fail due to overheating, reducing the reliability of the electronic equipment.

[0003] After searching, the announcement number CN218954828U is a new type of LED light board heat dissipation structure involving the technical field of LED light board structural accessories, including an LED light board and a sub-board. In the utility model, by aligning the bottom four corners of the LED light board with the top four corners of the sub-board, the cross-axis column on the bottom end of the first fixed column is inserted into the cross groove at the top end of the second fixed column, so that the LED light board can be installed and positioned using the sub-board, and the turbofan blades on the outer ring of the transmission shaft are rotated through the output end of the servo motor through the coupling, and the heat-conducting base conducts the heat generated by the right heating capacitor and the left heating capacitor to the hollow copper tube through itself, and reduces the heat through the coolant inside the liquid circulation hole, and conducts the uncompensated heat to the bottom of the cooling fins through the cooling fins, and the turbofan blades extract the heat and discharge it from the inside of the hollow sleeve through the dustproof net and the heat dissipation through the hole, so as to achieve efficient heat dissipation of the right heating capacitor and the left heating capacitor.

[0004] The above patent mentioned that "the LED light board can be installed and positioned using the sub-board, and the turbofan blades on the outer ring of the transmission shaft are rotated through the output end of the servo motor through the coupling, and the heat-conducting base conducts the heat generated by the right-side heating capacitor and the left-side heating capacitor to the hollow copper tube through itself, and reduces the heat through the coolant inside the liquid flow hole, and conducts the uncompensated heat to the bottom of the cooling fins through the cooling fins, and the turbofan blades extract the heat and discharge it through the dustproof net and the heat dissipation through-holes to the inside of the hollow sleeve, thereby achieving efficient heat dissipation of the right-side heating capacitor and the left-side heating capacitor". However, in the actual use process, after the LED light board is cooled for a long time, a lot of dust will accumulate on the dust shield, which will reduce the heat dissipation effect of the LED light board. Therefore, in response to the above problems, a heat dissipation type LED light board structure is proposed. Utility Model Content
