Problems solved by technology

This prior art can also be used for rail vehicles such as subways to have indoor lighting, but still has the following deficiencies: the LED illuminant is arranged on the regular polyhedron PCB circuit board column, and then is arranged on the two ends of the glass tube, and the fluorescent lamp is arranged on the glass tube. In the way of powder, the light output of the LED luminous body is not fully utilized, the light path in the glass tube is long, and the light attenuation is serious, resulting in a waste of energy; on the other hand, the regular polyhedron PCB circuit board structure is not conducive to heat dissipation
