Three ways to improve brightness for led tube lights
LED tube lamp brightness is determined by the operating current, the current will be relatively large number of bright, but each LED are all with rated operating current, such as: ordinary white mini LED current is 25MA so, if the current LED beyond ratings will cause premature or damage. Therefore, in order to ensure the life of the LED, generally increase the number of LED, or using high-power LED to enhance the brightness.
1. Improve power conversion efficiency, power consumption can be reduced
2. Increase led lamp beads luminous efficiency, improve light efficiency of single led lamp beads, this effect is more obvious.
3. Improve PC lampshade light transmittance. Fog light shade loss is relatively large, some as high as 25%, but can’t increase too much, because too much will lead to visible light led effect.
These three approaches used simultaneously, pay attention to the coordination, then led lamp brightness will be greatly improved. Currently Greenough high brightness led light, luminous efficiency of 138lm / w, namely 18w led tube light brightness reach 2400lm, a led lamp brightness to peer 2 led lamp brightness.
