Contamination Inside Headlamps

Increasing numbers of automotive parts are made of resin to reduce vehicle weight. Many resin parts are used also in headlamps. If resin parts are charged with static electricity and dust or other foreign particles adhere to them, the dust may enter inside the headlamp during assembly.
When entry of dust is discovered after assembly of the headlamp unit, the entire unit must be disposed of because it cannot be disassembled, resulting in a large loss.

Conventional countermeasures

Humidity control

  • The effect is uncertain.
  • Condensation may occur.

Countermeasures with static eliminators (ionizers)

An ionizer prevents the entry of foreign particles, which reduces the disposal cost of lamps.
