Description

Technical field [0001] The invention relates to the field of LED circuit boards, in particular to a new type of LED circuit board assembly. Background technique [0002] In the prior art LED circuit board, the main line of this prior art LED circuit board product is on the circuit board, that is, the main line sum located on both sides of the circuit board integrated with the circuit board, the main line and itself are the circuit A part of the conductive circuit layer of the board is generally copper foil, which is mainly used to guide the working current of the LED. [0003] In practical applications, for this kind of prior art LED circuit board, generally about 3 LED lights are connected in series to form a group, so that a number of LED lamp series groups are formed on the LED circuit board, and then the main lines on both sides of the circuit board These LED lights are connected in parallel in series. [0004] Typically, the head and end of the circuit board product have posit...

Problems solved by technology

[0005] However, since resistance is inevitable when the LED circuit board is too long, it should not be too long in series, otherwise it will cause excessive voltage attenuation

[0006] Moreover, if the LED circuit board is too long, and there are too many series groups of LED lamps connected in parallel, the main lines on both sides of the circuit board need to load too much current, resulting in excessive heat generation. This heat, together with the heat of the LED lamp itself, is not easy to dissipate quickly. , causing the LED lamp to work at too high a temperature, which in turn affects the luminous performance and reliability of the LED lamp and its service life

[0007] For this reason, circuit boards of the prior art often adopt wider and thicker copper foil circuit layers, because the cost of copper foil is high, this will inevitably lead to higher material costs, and its final heat dissipation performance and work reliability not ideal

For example, in the actual application of this prior art LED circuit board, the total length after connection is generally not more than 5 meters, otherwise the voltage decays too much, it is difficult to ensure the normal operating voltage of all LED lamps, and the heat generation is too large and the heat dissipation The effect is not good, and it is difficult to apply in high-demand applications
