Heat Dissipating Structure Of LED Circuit Board And LED Lamp Tube Comprised Thereof

An LED tube including a heat dissipating structure of an LED circuit board, comprising:

• an LED circuit board having a light radiating surface and a heat dissipating surface opposite to the light radiating surface, and the heat dissipating surface disposing a plurality of soldering points thereon and the light radiating surface disposing a plurality of LEDs thereon;
• a coating layer coating on the heat dissipating surface to cover the soldering points, wherein the coating layer is composed of Nanoparticles and a bonding agent, and is exposed to the environment;
• and
• a lamp tube for containing the LED circuit board, the lamp tube having a plurality of heat dissipation holes disposed on the left and right sides of the tube, the heat dissipation holes face toward the heat dissipating surface of the LED circuit board.
