The LED integrated chip circuit block is composed of a printed circuit board and a plurality of light-emitting diodes arranged on it. The LED integrated chip circuit block is arranged in the housing. The housing is composed of a base and a transparent cover. The LED integrated chip circuit block is arranged in a cavity formed by the base and the transparent cover, and the light emitting diode faces the transparent cover.

The other two sides on the bottom are openings. The two sides and the bottom form a space for accommodating the light guide component. The inner wall of the side part is correspondingly provided with a recess for accommodating the LED integrated chip circuit block and a ladder-like structure that is matched and fixed with the recess on the light guide assembly. The above-mentioned openings on both sides are used to install side covers and terminals, respectively. The LED integrated chip circuit block is electrically connected.

The LED integrated chip circuit block 2 is located on the side of the light guide assembly 3, and the front of the light guide assembly 3 serves as the light emitting surface of the lamp tube. The light emitted from the LED integrated chip circuit block 2 is incident from the side of the light guide component, and exits from the front after being guided by the light guide component 3. Since the light is not directly emitted, it can effectively solve the uneven light phenomenon and avoid glare or dark shadows.
具体地，该导光组件3包括透光层4、设于透光层4一面的增透层5及设于透光层4另一面的波浪状反射层6，该LED集成芯片电路块2位于透光层4侧面，由LED集成芯片电路块2发射的光进入透光层4，经波浪状结构层6反射后，通过透光层4由增透层5射出。Specifically, the light guide assembly 3 includes a light-transmitting layer 4, an anti-reflection layer 5 provided on one side of the light-transmitting layer 4, and a wavy reflective layer 6 provided on the other side of the light-transmitting layer 4.
