Problems solved by technology

[0004] 1. The heat dissipation area is small: the heat is dissipated by a piece of aluminum substrate under the circuit board, and the heat of the light-emitting diode is mainly generated by its negative terminal. The heat must first pass through the circuit board to be transmitted to the aluminum substrate, and the circuit board itself will block the flow of heat. Conduction, poor cooling effect
[0005] 2. Poor light concentrating effect: each light emitting diode can be regarded as a point light source, and the light emitted by it includes side light and scattered light, which cannot be converged, which reduces the brightness of the light stick, and must be compensated by increasing the number of light emitting diodes Lack of brightness
[0006] 3. Short length: relying only on the support of the sheet-shaped aluminum substrate, the structural strength is poor, and it
