Abstract:
A projector apparatus equipped with a metal plate structure serving as a light shield against a light source and as a heat radiator is provided. The metal plate structure is arranged over the light source to hide the light source. The metal plate structure extends farther to a cooling fan and connects to the upper end of the air expiration face of the fan. The metal plate structure thus serves as the top plate of the baffle section of the exhaust duct of the fan for leading the air expired from the fan. The metal plate structure also serves as a shield plate, which can be connected to a grounded metal piece.
