Abstract

The invention relates to the field of LED (light emitting diode) pixel tubes, in particular to an LED pixel tube light distribution process and an LED pixel tube, wherein through the LED pixel tube light distribution process, the LED pixel tube has good light intensity angle distribution. The process comprises the following steps that an LED wafer is fixedly arranged in a wire leading support frame lamp cup; a wafer welding point is welded with a support frame welding wire region of the wire leading support frame lamp cup; light ray diffusion agents are filled in the wire leading support frame lamp cup subjected to wire welding; the lens encapsulation is carried out in a mold cavity; and lens materials subjected to the lens encapsulation are cured in the mold cavity. The LED pixel tube light distribution process and the LED pixel tube provided by the invention have the advantages that a proper number of light ray diffusion agents are filled in the support frame lamp cup subjected to wire welding, light emitted by the wafer is subjected to reflection of the lamp cup, diffuse reflection of the diffusion agents and refraction of an encapsulation lens, and then, the uniform light intensity angle distribution is formed. The LED pixel tube capable of realizing the advantages of the large viewing angle, mellow light distribution curve and high angle superposition degree is provided.

Description

technical field [0001] The invention relates to the field of LED pixel tubes, in particular to an LED pixel tube light distribution process and an LED pixel tube for making the LED pixel tubes have good light intensity angle distribution. Background technique [0002] As LEDs, as a new generation of light sources, are increasingly used in people's work and life, their applications are becoming more and more extensive. Among them, a large number of LED outdoor display screens are used, which drives the demand for LED pixel tubes. Due to the requirements of the outdoor display screen for display clarity and viewing angle, compared with ordinary LEDs, as the main components of LED display screens, LED pixel tubes need to have a large viewing angle, small angle deviation, and light distribution curve coincidence. high feature. [0003] The light distribution curve of the LED pixel tube manufactured by the general LED packaging process has a sharp peak, which is easy to cause t...
