Abstract
The invention relates to a light distribution method of a profiled microprism LED fluorescent lamp tube. The profiled microprism LED fluorescent lamp tube mainly comprises a PC (Polycarbonate) outer cover, a radiator, LED lamp beads, a power supply, an end cap and the like. The light distribution method comprises the following steps of: (1) arranging the LED lamp beads by a single row under the condition that the luminous intensity meets requirements, and arranging the LED lamp beads by multiple rows under the condition that the luminous intensity can not meet the requirements; and (2) carrying out concave lens structural design processing on the inner surface of the PC outer cover to make the radian of a concave lens not exceed the Brewster angle when light beams are stretched in the radial direction. The invention effectively eliminates the light spots and the glare of common LED lamp tubes by utilizing the profiled microprism design and meanwhile improves the LED luminous emissivity.
