Patent ID: 7618148

Claim:
A projector apparatus comprising: an electrically conductive housing including a lower housing part and an upper housing part coupled to said lower housing part for covering said lower housing part; an internal projector module mounted in said housing; a first grounding component provided between said internal projector module and said upper housing part so as to establish a first grounding path between said internal projector module and said housing; and a second grounding component provided between said internal projector module and said lower housing part so as to establish a second grounding path between said internal projector module and said housing, wherein said lower housing part includes a bottom plate and said second grounding component is disposed between said bottom plate and said internal projector module, wherein said internal projector module includes an optical engine and a main support coupled to said optical engine at an underside of said optical engine and disposed proximate to said bottom plate of said lower housing part, wherein said main support is made from an electrical insulating material, said optical engine has an electrically conductive surface, and said projector apparatus further comprises a conducting member provided on said main support connected electrically to said electrically conductive surface of said optical engine and sandwiched between said main support and said second grounding component.
