LIGHT HEAD FOR USE IN PIPE LINING Russian patent published in 2020 - IPC F16L55/40 F16L55/162 F16L55/165 F16L55/18 B29C35/08 

FIELD: lining of pipes.

SUBSTANCE: invention relates to lining of pipes, such as pipes for kitchen and sewage, in particular to light head for use in pipe lining. Light head (200) for use in pipe lining has near-end cover (204) with an air inlet opening, a far end cover (208) and a housing between the near-end cover and the far-end cover. In the housing there is a longitudinal hole and an air channel. Longitudinal hole passes from the cover of the near end through the center of the housing to the far end cap. Air channel passes in radial direction from said longitudinal hole to radial outlet for air. Lengthwise hole is made with possibility to receive air from inlet hole for air so that when using air from the air inlet passes through the housing and enters the radial outlet for air. Light-emitting diode (240) is attached to the housing on its periphery for radiation of light in radial direction from light head (200) in direction of the pipe.

EFFECT: technical result consists in the possibility of using a light head in the lining of bent pipes or pipes with straight angles and avoiding overheating of the light head.
