AI Technical Summary
Existing LED tubes lack directional light constraint, resulting in high light scattering loss, high power consumption, and unconcentrated illumination area, which cannot meet the requirements of fixed-point lighting.
The high-efficiency lamp optical system, which adopts coaxial alignment assembly, includes a tubular shell, a central light source plate, a sawtooth refraction component, and a light-transmitting cover. The sawtooth refraction component corrects and focuses the angle of lateral light, realizing the full-area recovery and efficient utilization of light.
Achieving high-brightness lighting with low power consumption improves light utilization, allows for controllable light output angle, provides precise point lighting, reduces heat accumulation, and extends lamp life.
