<P>PROBLEM TO BE SOLVED: To provide a light-emitting diode light tube for illumination that can hardly reduce illumination intensity and attaining a uniform light source without having bright spots. <P>SOLUTION: The light-emitting diode light tube 100 for illumination includes a light-transmitting tube 110, a fluorescent powder layer 120, and a substrate 130. The fluorescent powder layer 120 is applied to the surface of the light-transmitting tube 110, and thickness of the fluorescent powder layer 120 is 10-100 μm. The substrate 130 is arranged inside the light-transmitting tube 110, and supports a plurality of light-emitting diodes 131. When a distance between the light-emitting diodes 131 and the light-transmitting tube 110 is set up to be H and a distance between installed positions of two light-emitting diodes 131 is set up to be P, H/P is≥ 0.134, and H is 9.5-38 mm. Thus, the light-emitting diode light tube 100 for illumination can improve its uniformity of the light source, and hardly spoils the illumination intensity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
