A gain structure of an LED tubular lamp for uniforming light and dissipating heat is disclosed. The gain structure allows the LED tubular lamp to give out even illuminance without eye-offending peak illuminance of LED chips. The LED tubular lamp has an illuminator, which includes a substrate equipped with spaced LED chips, wherein the LED chips are arranged in a density equal to or greater than 2 chips/cm2, so that the LED chips illuminate through the frosted housing jointly present pleasing, uniform illuminance. The substrate is provided with metal sheets serving to absorb heat generated by the LED chips that are illuminating, so as to accelerate heat dissipation and thereby prevent the LED chips from premature aging that degrade their brightness. |
