Definitions

  • Figure 5 shows in perspective view the light module 1 in use.
  • Cold air Ac is supplied through channel 8 in the mounting beam 2 then through an opening 21 the air flows along the backside of the mounting plate 15 and the ribs 19 and after the air is heated it returns through the channel 9 as hot air Ah.
